How to use this page

Work in order and attempt each question before you open the reasoning — the first question of each domain is fully modelled, the second asks you for one decision, and the rest are hidden behind a toggle so you try first. When you finish a domain, read its “Check yourself” line, because it turns a wrong answer into a specific thing to drill rather than a vague feeling that reading is hard.

Craft and Structure — questions 1 to 8

Eight questions. Five ask for one missing word, two ask what a whole text is for, and one asks what two texts agree on.

Question 1, Module 1 — Craft and Structure: Words in Context (Easy)

I do — watch me work it

Module 1 opens with five vocabulary questions in a row. Watch how I do the first one, because the same four steps solve all five.

green, solid underline = the evidence that proves the answer

Which choice completes the text with the most logical and precise word or phrase?

1. A) widespread
2. B) careful
3. C) unintended
4. D) infrequent

Question 2, Module 1 — Craft and Structure: Words in Context (Easy)

We do — you make one call, then read on

Same question type, one item later. This time you make the prediction before I show you the highlights.

Which choice completes the text with the most logical and precise word or phrase?

1. A) delegate
2. B) compose
3. C) interpret
4. D) renounce

yellow, dotted = the words the question turns on · green, solid underline = the evidence that proves the answer

Question 3, Module 1 — Craft and Structure: Words in Context (Easy)

Your turn — try it before you open the reasoning

Third vocabulary item. From here on you attempt it cold.

Which choice completes the text with the most logical and precise word or phrase?

1. A) impartial
2. B) offhand
3. C) persistent
4. D) mandatory

Try it first — then open the reasoning

Beginning in the 1950s, Navajo Nation legislator Annie Dodge Wauneka continuously worked to promote public health; this   effort involved traveling throughout the vast Navajo homeland and writing a medical dictionary for speakers of Diné bizaad, the Navajo language.

green, solid underline = the evidence that proves the answer

Correct: C) persistent
The semicolon splits the sentence into two halves that say the same thing twice. The first half says Wauneka "continuously worked" from the 1950s onward. The second half describes the blank word as the label for that effort. "Persistent" means keeping at something over a long time — a direct echo of "continuously." The examples back it up: travelling across a vast homeland and writing a whole dictionary are not quick jobs.

A) impartial — scope shift. "Impartial" means not taking sides. Fairness is never at issue here. The passage is about how long and how hard Wauneka worked, not about whether she favoured anyone.

B) offhand — opposite. "Offhand" means casual and done without preparation. Writing a medical dictionary is the opposite of casual, and "continuously worked" rules it out directly.

D) mandatory — unsupported. "Mandatory" means required by a rule. Nothing says anyone ordered Wauneka to do this work. She was a legislator who chose the project.

The move — Find the Echo Word: When a sentence uses a semicolon or a colon, the two halves usually restate each other. Hunt the half you can read for the word that echoes the blank. It fires on any blank sitting near a semicolon, colon or dash. It saves about fifteen seconds per vocabulary item. Fill the Blank Yourself then turns that echo into your prediction.
Also firing on this question: Fill the Blank Yourself.

Question 4, Module 1 — Craft and Structure: Words in Context (Easy)

Your turn — try it before you open the reasoning

The passages in this run get longer, but the job does not change.

Which choice completes the text with the most logical and precise word or phrase?

1. A) tranquil
2. B) dangerous
3. C) imaginative
4. D) surprising

Try it first — then open the reasoning

Kelp forests grow underwater along the eastern Pacific Coast. These underwater forests are important to fish and other marine animals. Ocean currents can be powerful and rough, making it difficult for animals to find safe places to hide from predators. The underwater forests slow down the currents. This creates a more   environment with calmer waters where animals can take shelter.

green, solid underline = the evidence that proves the answer · red, dashed = what pulls you toward a wrong choice

Correct: A) tranquil
The words right after the blank hand you the definition: "calmer waters where animals can take shelter." "Tranquil" means calm and peaceful. The kelp slows the currents down, so the water it creates is calmer than the rough water outside. A is the same idea in one word.

B) dangerous — opposite. "Dangerous" describes the powerful, rough currents outside the kelp forest — the thing the forest protects animals from. Picking B reverses the sentence.

C) imaginative — scope shift. "Imaginative" describes creative thinking. Water cannot be imaginative, and nothing in this text is about creativity.

D) surprising — true-but-off-goal. Kelp forests may well surprise a reader, but "surprising" does not describe calm water, and the sentence supplies "calmer waters" as its own definition of the blank.

The move — Find the Echo Word: The echo can sit after the blank as easily as before it. Here "calmer waters" is the echo and it arrives four words later. It fires on any blank followed by a describing phrase. It saves you from grading four vocabulary words you never needed to weigh.
Also firing on this question: Fill the Blank Yourself · True About the Text Is Not the Same as Right.

⚠ Trap: Choice B is built out of real words from the passage — "powerful and rough" — but attached to the wrong noun. A choice can be true about the text and still be the wrong answer to the sentence.

Question 5, Module 1 — Craft and Structure: Words in Context (Medium)

Your turn — try it before you open the reasoning

The last vocabulary item in the run, and the first one with an abstract passage.

Which choice completes the text with the most logical and precise word or phrase?

1. A) indistinct
2. B) irrelevant
3. C) indisputable
4. D) implicit

Try it first — then open the reasoning

People sometimes dismiss a claim if it comes from a source they regard as self-interested, but from a strictly logical perspective, the source of a claim is  : it has no direct bearing on whether the claim is true.

green, solid underline = the evidence that proves the answer · red, dashed = what pulls you toward a wrong choice

Correct: B) irrelevant
The colon defines the blank for you: the source "has no direct bearing on whether the claim is true." Something with no bearing on the question is beside the point. "Irrelevant" means exactly that. The word "but" earlier also tells you the second half will push against the first: people do judge by source, yet logically the source does not matter.

A) indistinct — wrong-relationship. "Indistinct" means blurry or hard to make out. The source in this passage is perfectly clear — people can see it and judge it. The problem is that it does not matter, not that it is fuzzy.

C) indisputable — opposite. "Indisputable" means impossible to argue with. That would make the source matter enormously. The text says the source has no bearing at all, so C flips the meaning.

D) implicit — scope shift. "Implicit" means suggested but not stated. Whether the source is stated or hinted at is a different question from whether it affects the truth of a claim.

The move — Read Past the Blank: On an abstract passage, translate the definition after the colon into plain words before you touch the choices. "No direct bearing" becomes "does not matter" becomes "irrelevant." It fires whenever a colon follows the blank. It saves you from choosing on the sound of the word instead of its meaning.
Also firing on this question: Find the Echo Word · Fill the Blank Yourself · Colon Means Proof Follows.

Question 6, Module 1 — Craft and Structure: Text Structure and Purpose (Easy)

Your turn — try it before you open the reasoning

Vocabulary ends here. The next two questions ask what a whole text is for.

Which choice best states the main purpose of the text?

1. A) It explains why audiences prefer some kinds of music over others.
2. B) It discusses the development of a dance form.
3. C) It describes how to play a musical instrument.
4. D) It emphasizes the popularity of a famous dancer.

Try it first — then open the reasoning

Jazz tap is a dance form that was first developed in African American communities. Jazz tap was heavily influenced by jazz music, which became widely popular in the United States in the 1920s. Tap dancers were inspired by jazz music’s quick rhythms and by the way jazz musicians would make up melodies as they played. As jazz music continued to develop in the 1930s and 1940s, jazz tap evolved with it. Because of jazz music’s influence, jazz tap quickly developed into a dance form that was very different from earlier kinds of tap dance.

green, solid underline = the evidence that proves the answer · red, dashed = what pulls you toward a wrong choice

Correct: B) It discusses the development of a dance form.
Track what every sentence is about. Sentence one: jazz tap is a dance form. Sentence four: jazz tap evolved. Sentence five: jazz tap developed into something new. Every sentence lands on jazz tap growing and changing. "It discusses the development of a dance form" covers the whole text with no leftovers.

A) It explains why audiences prefer some kinds of music over others. — scope shift. Audience preference never appears. The text says jazz music was popular, but it never explains why people prefer one music over another.

C) It describes how to play a musical instrument. — unsupported. No instrument is ever taught or even described. The mention of musicians making up melodies is one clause, not the point of the passage.

D) It emphasizes the popularity of a famous dancer. — half-right. Popularity does appear — jazz music "became widely popular." But no dancer is named anywhere, so "a famous dancer" has nothing to attach to.

The move — Purpose Is the Whole Text: A purpose answer has to cover every sentence, not the most interesting one. Ask "does this choice describe sentence one and the last sentence?" It fires on every "main purpose" and "main idea" stem. It saves you from the choice built out of one vivid detail.

Question 7, Module 1 — Craft and Structure: Text Structure and Purpose (Hard)

Your turn — try it before you open the reasoning

The first literature passage of the module, and the first genuinely hard item. Read Tom’s speech twice before you look at the choices.

Which choice best states the main purpose of the text?

1. A) To offer Tom’s assurance that the play will be inoffensive and involve only a small number of people
2. B) To clarify that the play will not be performed in the manner Tom had originally intended
3. C) To elaborate on the idea that the people around Tom lack the skills to successfully stage a play
4. D) To assert that Tom believes the group performing the play will be able to successfully promote it

Try it first — then open the reasoning

The passage opens with an italic set-up line, then the speech itself. Both are part of the stimulus.

The following text is adapted from Jane Austen’s 1814 novel Mansfield Park. The speaker, Tom, is considering staging a play at home with a group of his friends and family.

We mean nothing but a little amusement among ourselves, just to vary the scene, and exercise our powers in something new. We want no audience, no publicity. We may be trusted, I think, in choosing some play most perfectly unexceptionable; and I can conceive no greater harm or danger to any of us in conversing in the elegant written language of some respectable author than in chattering in words of our own.

green, solid underline = the evidence that proves the answer · red, dashed = what pulls you toward a wrong choice

Correct: A) To offer Tom’s assurance that the play will be inoffensive and involve only a small number of people
Tom is calming somebody down. Two promises run through the speech. First, small: "a little amusement among ourselves," "We want no audience, no publicity." Second, harmless: the play will be "perfectly unexceptionable," and he can see "no greater harm or danger" in it than in ordinary chatting. "Unexceptionable" means nobody could object to it — that is what "inoffensive" means in choice A. A names both promises, and nothing else.

B) To clarify that the play will not be performed in the manner Tom had originally intended — unsupported. Nothing is being changed. Tom is describing the plan he wants, not correcting an earlier version of it. There is no "originally intended" anywhere in the speech.

C) To elaborate on the idea that the people around Tom lack the skills to successfully stage a play — opposite. Tom says "We may be trusted, I think." He is arguing that the group is capable, not that it lacks skill. C reverses his claim.

D) To assert that Tom believes the group performing the play will be able to successfully promote it — wrong-relationship. "Promote it" means advertise it. Tom explicitly rules that out: "We want no audience, no publicity." D takes the one thing Tom refuses and makes it his goal.

The move — Purpose Is the Whole Text: On an old literary passage, ignore the vocabulary you do not know and ask what the speaker is doing: arguing, refusing, promising, apologising. Tom is reassuring. Then find the choice that names that action. It fires on every literature purpose question. It saves you from having to translate every word of 1814 English.
Also firing on this question: Name What the Speaker Is Doing.

⚡ Shortcut: Two words carry this whole item. "Unexceptionable" = nobody can object. "No publicity" = small and private. Choice A says both. If you find the two words, you do not need the rest of the sentence.

Question 8, Module 1 — Craft and Structure: Cross-Text Connections (Medium)

Your turn — try it before you open the reasoning

The only two-text item in Module 1. You are looking for the one statement both authors would sign.

Based on the texts, both authors would most likely agree with which statement?

1. A) Gold frames were considered especially desirable by those who purchased works from Impressionist painters.
2. B) The colors in an Impressionist painting were often chosen to complement the colors of the frame it would be placed in.
3. C) Many Impressionist painters were intentional about the frames they selected for their works.
4. D) Degas’s preferred framing style was different from that of most Impressionist painters.

Try it first — then open the reasoning

Text 1
French Impressionist artist Edgar Degas insisted that his paintings be kept in their original frames after they were sold. Like many Impressionist painters, Degas used painted frames that stood in contrast to the gold frames frequently seen at the Paris Salon, a prestigious art exhibition that was sponsored by the French government and promoted traditional painting styles. Impressionist painters likely chose these colorful frames to distinguish themselves from what was considered conventional at the time.

Text 2
Impressionist painters often focused on the interplay of color and light in their works. As such, those Impressionists who placed their works in painted frames instead of the more traditional gold ones did so for aesthetic reasons: a frame’s color was likely chosen because it would harmonize with the colors or subjects in a painting. Gold, conversely, could distract from the subtleties in a painted scene.

green, solid underline = the evidence that proves the answer · red, dashed = what pulls you toward a wrong choice

Correct: C) Many Impressionist painters were intentional about the frames they selected for their works.
The two texts disagree about why Impressionists picked painted frames. Text 1 says they did it to stand apart from convention. Text 2 says they did it for how it looked next to the painting. But both say the painters chose on purpose. Text 1: "likely chose these colorful frames to distinguish themselves." Text 2: "did so for aesthetic reasons." C states only the part they share — the choosing was deliberate — and takes no side on the reason.

A) Gold frames were considered especially desirable by those who purchased works from Impressionist painters. — unsupported. Neither text says a word about what buyers wanted. Text 1 mentions the Paris Salon liking gold frames; that is an exhibition, not a group of purchasers.

B) The colors in an Impressionist painting were often chosen to complement the colors of the frame it would be placed in. — reversed. Text 2 says the frame’s colour was chosen to harmonise with the painting. B turns it around and says the painting’s colours were chosen to match the frame. Same two nouns, opposite direction.

D) Degas’s preferred framing style was different from that of most Impressionist painters. — half-right. Text 1 says the opposite: Degas used painted frames "like many Impressionist painters." He is presented as typical, not unusual. Text 2 never mentions Degas at all, so it cannot agree either.

The move — Agree Means Both Texts Say It: On a "both authors would agree" question, write one word for what each text claims, then pick the choice that is inside both circles. Anything only one text supports is out, even if it is true. It fires on every dual-text item. It saves you from the choice that quotes Text 1 beautifully and ignores Text 2.
Also firing on this question: True About the Text Is Not the Same as Right.

⚠ Trap: Two-text items reward the blandest-looking choice. "Many Impressionist painters were intentional about the frames" sounds weak next to the specific-sounding wrong answers. Vague is often what "both agree" looks like.

Information and Ideas — questions 9 to 15

Seven questions. Two central-idea items, two evidence items, one graph item, and two inference completions.

Question 9, Module 1 — Information and Ideas: Central Ideas and Details (Easy)

I do — watch me work it

New domain, new ladder. I work this one all the way through so you can see how a "central idea" answer gets built.

green, solid underline = the evidence that proves the answer · red, dashed = what pulls you toward a wrong choice

Which choice best describes Gibson’s approach to art, as presented in the text?

1. A) He draws from traditional Native art forms to create his original works.
2. B) He has been influenced by Native and non-Native artists equally.
3. C) He finds inspiration from boxing in designing the dresses he makes.
4. D) He rejects expectations about color and pattern when incorporating beadwork.

Question 10, Module 1 — Information and Ideas: Central Ideas and Details (Medium)

We do — you make one call, then read on

Same skill, one decision for you before I show the highlights.

Which choice best states the main idea of the text?

1. A) Although inhabiting a home surrounded by fanciful features such as those designed by Gins and Arakawa can be rejuvenating, it is unsustainable.
2. B) Designing disorienting spaces like those in the Gins and Arakawa building is the most effective way to create a physically stimulating environment.
3. C) As a filmmaker, Yamaoka has long supported the designs of conceptual artists such as Gins and Arakawa.
4. D) Although impractical, the design of the apartment building by Gins and Arakawa may improve the well-being of the building’s residents.

yellow, dotted = the words the question turns on · green, solid underline = the evidence that proves the answer

Question 11, Module 1 — Information and Ideas: Command of Evidence (Textual) (Medium)

Your turn — try it before you open the reasoning

A hypothesis is on the table and you have to find the result that would back it.

Which finding, if true, would most directly support the team’s idea?

1. A) On average, participants found most of the purple wings and blue wings and far fewer of the iridescent wings.
2. B) On average, participants found the iridescent wings faster than they found the purple wings or blue wings.
3. C) Some participants reported that the purple wings were easier to see than the blue wings.
4. D) Some participants successfully found all of the wings on the leaves.

Try it first — then open the reasoning

Many insects are iridescent, or have colors that appear to shimmer and change when seen from different angles. Scientists have assumed that this feature helps to attract mates but could also attract predators. But biologist Karin Kjernsmo and a team had the idea that the shifting appearance of colors might actually make it harder for other animals to see iridescent insects. To test this idea, the team put beetle forewings on leaves along a forest path and then asked human participants to look for them. Some of the wings were naturally iridescent. Others were painted with a nonchanging color from the iridescent spectrum, such as purple or blue.

yellow, dotted = the words the question turns on · green, solid underline = the evidence that proves the answer · red, dashed = what pulls you toward a wrong choice

Correct: A) On average, participants found most of the purple wings and blue wings and far fewer of the iridescent wings.
Write the team’s idea as a prediction before you read the choices: if iridescence hides an insect, people will spot iridescent wings less often than plain ones. Choice A is that prediction, stated as a result — participants found most of the purple and blue wings and far fewer of the iridescent ones. The two groups in the experiment are exactly the two groups A compares.

B) On average, participants found the iridescent wings faster than they found the purple wings or blue wings. — opposite. Finding the iridescent wings faster means iridescence made them easier to see. That is the reverse of the team’s idea, so B would weaken it, not support it.

C) Some participants reported that the purple wings were easier to see than the blue wings. — scope shift. Purple versus blue is a comparison between two plain colours. The team’s idea is about iridescent versus plain. C compares the wrong pair, so it says nothing either way.

D) Some participants successfully found all of the wings on the leaves. — irrelevant. If some participants found all the wings, the two groups came out equal for those people. That gives no comparison at all, and "some participants" is too small a claim to support anything.

The move — Support Means the Prediction Comes True: Turn the researcher’s idea into an "if…then" sentence in your own words, then find the choice that matches the "then" half. It fires on every "which finding would support / weaken" stem. It saves you from choices that are about the right topic but the wrong comparison.

⚠ Trap: Choice C is the classic wrong pair. The experiment had two conditions — iridescent and plain. Any choice comparing plain to plain is off the point no matter how scientific it sounds.

Question 12, Module 1 — Information and Ideas: Command of Evidence (Textual) (Medium)

Your turn — try it before you open the reasoning

A quotation-bank item. Four lines from a play, and only one of them does the job the claim describes.

Which quotation from The Post Office most effectively illustrates the claim?

1. A) “I see, you don’t wish to stop; I don’t care to stay on here either.”
2. B) “Oh, flower gathering? That is why your feet seem so glad and your anklets jingle so merrily as you walk.”
3. C) “I’ll pay when I grow up—before I leave to look for work out on the other side of that stream there.”
4. D) “Wish I could be out too. Then I would pick some flowers for you from the very topmost branches right out of sight.”

Try it first — then open the reasoning

Here is the same passage with the two halves of the claim marked. The quotation has to satisfy both halves at once.

The Post Office is a 1912 play by Rabindranath Tagore, originally written in Bengali. The character Amal is a young boy who imagines that the people he sees passing the window of his home are carefree even when engaged in work or chores, as is evident when he says to the daughter of a flower seller,  

yellow, dotted = the words the question turns on

Correct: B) “Oh, flower gathering? That is why your feet seem so glad and your anklets jingle so merrily as you walk.”
The claim has two parts. Amal must be talking to the flower seller’s daughter, and he must be imagining that her work looks joyful. Choice B does both. "Flower gathering" is her chore. "Your feet seem so glad and your anklets jingle so merrily" is Amal reading joy into that chore. That is the claim in one line.

A) “I see, you don’t wish to stop; I don’t care to stay on here either.” — unsupported. Nobody is described as carefree here, and no work is mentioned. It is a line about leaving, and it says nothing about how a passer-by looks.

C) “I’ll pay when I grow up—before I leave to look for work out on the other side of that stream there.” — wrong-relationship. This is about Amal’s own future work, not somebody else’s present chore. And it sounds resigned, not carefree.

D) “Wish I could be out too. Then I would pick some flowers for you from the very topmost branches right out of sight.” — half-right. Flowers appear, which makes D feel close. But Amal is describing what he would do if he could go out. The claim is about how he sees other people at work, not about his own wishes.

The move — A Quotation Must Show, Not Tell: Split the claim into its two or three requirements and test each quotation against all of them. A quotation that matches one requirement and misses another is out. It fires on every "which quotation illustrates the claim" item. It saves you from the choice that shares a keyword with the claim.

⚡ Shortcut: Keyword overlap is bait here. Choice D contains "flowers" and is wrong; choice B contains "flower gathering" and is right. Match the action described in the claim, not the noun.

Question 13, Module 1 — Information and Ideas: Command of Evidence (Quantitative) (Hard)

Your turn — try it before you open the reasoning

The one figure in Module 1, and the hardest question in this domain. You have to read a bar graph and then use it against a conclusion.

Which choice best describes data from the graph that weaken the student’s conclusion?

1. A) The spider population count was the same in both enclosures on day 1.
2. B) The spider population count also substantially declined by day 30 in the enclosure without lizards.
3. C) The largest decline in spider population count in the enclosure with lizards occurred from day 1 to day 10.
4. D) The spider population count on day 30 was lower in the enclosure with lizards than in the enclosure without lizards.

Try it first — then open the reasoning

Now the same figure with the decisive bars marked, on the chart and again in the table below it. Compare the light "no lizards" bar on day 1 with the light "no lizards" bar on day 30.

Rebuilt from page 13 — annotated (bar heights APPROXIMATE, read from the printed 0–90 axis)

The source graph prints this numbered vertical axis (0 to 90 in steps of 10) with a gridline at every tick, but it prints no value on any bar. Every bar height below is read against that printed scale, so each is approximate to about half a gridline step — about 5 spiders.

green, solid underline = the evidence that proves the answer · red, dashed = what pulls you toward a wrong choice

To investigate the effect of lizard predation on spider populations, a student in a biology class placed spiders in two enclosures, one with lizards and one without, and tracked the number of spiders in the enclosures for 30 days. The student concluded that the reduction in the spider population count in the enclosure with lizards by day 30 was entirely attributable to the presence of the lizards.

yellow, dotted = the words the question turns on

Correct: B) The spider population count also substantially declined by day 30 in the enclosure without lizards.
The student’s claim contains one very strong word: entirely. To weaken it you need evidence that something else also pushed the spider numbers down. The graph gives it. In the enclosure with no lizards at all, the count still fell from about 85 on day 1 to about 43 on day 30 — roughly a halving. If spiders decline that much with no lizards present, the lizards cannot be the whole cause. B says exactly that.

A) The spider population count was the same in both enclosures on day 1. — irrelevant. Equal starting counts is good experimental design. It tells you the two groups began the same, which if anything makes the comparison more trustworthy. It says nothing about what caused the later drop.

C) The largest decline in spider population count in the enclosure with lizards occurred from day 1 to day 10. — true-but-off-goal. Read against the axis, the with-lizards count falls from about 85 to about 32 between day 1 and day 10 — the biggest single drop. That is true, and it is about the lizard enclosure only, so it does nothing to challenge the word "entirely."

D) The spider population count on day 30 was lower in the enclosure with lizards than in the enclosure without lizards. — opposite. Day 30 shows about 23 with lizards against about 43 without. That gap is the student’s own evidence. D strengthens the conclusion instead of weakening it.

The move — Read the Axis First: Before you read a single choice, read the axis labels and the legend, then say what one bar means in a full sentence: "on day 30, the enclosure without lizards held about 43 spiders." It fires on every graph or table item. It saves you from choices that describe a bar that is not there. Weaken Means Find the Other Cause then does the reasoning: to break "entirely," show the same effect happening without the supposed cause.
Also firing on this question: Weaken Means Find the Other Cause · Check the Strongest Word.

⚡ Shortcut: Hunt the control group. When a conclusion blames one factor, the weakening evidence almost always lives in the column where that factor is absent — here, "no lizards."

⚠ Trap: "Entirely" is the whole question. Cross out the word and choice D looks fine. Leave it in and only B touches it. Extreme words in a conclusion are where weaken questions attack.

Question 14, Module 1 — Information and Ideas: Inferences (Hard)

Your turn — try it before you open the reasoning

An inference item. The passage stops mid-sentence and you finish the researchers’ own thought.

Which choice most logically completes the text?

1. A) identify molecular components similar to EBF that target the activation of Or31 receptors.
2. B) investigate alternative methods for extracting EBF molecules from chrysanthemums.
3. C) verify the precise locations of Or31 and other odor receptors on mosquitoes’ antennae.
4. D) determine the maximum number of different odor receptors that can be activated by a single molecule.

Many mosquito repellents contain natural components that work by activating multiple odor receptors on mosquitoes’ antennae. As the insects develop resistance, new repellents are needed. Ke Dong and her team found that EBF, a molecular component of a chrysanthemum-flower extract, can repel mosquitoes by activating just one odor receptor—and this receptor, Or31, is present in all mosquito species known to carry diseases. Therefore, the researchers suggest that in developing new repellents, it would be most useful to  

yellow, dotted = the words the question turns on · green, solid underline = the evidence that proves the answer · red, dashed = what pulls you toward a wrong choice

Correct: A) identify molecular components similar to EBF that target the activation of Or31 receptors.
Follow the chain the passage builds. New repellents are needed. EBF works by hitting one receptor, Or31. Or31 exists in every disease-carrying mosquito species. So a chemical that hits Or31 would work on all of them. The word "Therefore" tells you the ending must be the payoff of that chain: look for more molecules like EBF that target Or31. Choice A is that sentence.

B) investigate alternative methods for extracting EBF molecules from chrysanthemums. — scope shift. Extraction method is a manufacturing question. The passage’s chain is about which receptor to aim at, not about how to get EBF out of a flower more cheaply.

C) verify the precise locations of Or31 and other odor receptors on mosquitoes’ antennae. — true-but-off-goal. The passage already treats Or31’s presence as known — it says the receptor "is present in all mosquito species known to carry diseases." Re-verifying a fact the argument already relies on is not the useful next step.

D) determine the maximum number of different odor receptors that can be activated by a single molecule. — reversed. The point of EBF is that it activates just one receptor and that is enough. D chases the maximum number of receptors, which is the old approach the first sentence describes.

The move — Finish the Logic Chain: When a result word — "therefore," "thus," "so," "consequently" — sits anywhere in the blank’s clause, the missing ending is the conclusion of the facts stacked above it. List those facts in order, then pick the choice that uses all of them. It fires on every "most logically completes the text" item. It saves you from choices that restate one fact instead of finishing the argument.
Also firing on this question: Read Past the Blank.

⚠ Trap: Choice C is built from real words in the passage — Or31, odor receptors, antennae — arranged into a task nobody needs. Word overlap is not evidence.

Question 15, Module 1 — Information and Ideas: Inferences (Medium)

Your turn — try it before you open the reasoning

Same skill, cleaner logic. This is the easier of the two inference items, so use it to check the move.

Which choice most logically completes the text?

1. A) making individual E. esula plants more susceptible to existing chemical herbicides.
2. B) enhancing the ecological benefits of E. esula in North America.
3. C) enabling cattle to consume E. esula without becoming sick.
4. D) reducing invasive E. esula numbers without harming other organisms.

Try it first — then open the reasoning

Euphorbia esula (leafy spurge) is a Eurasian plant that has become invasive in North America, where it displaces native vegetation and sickens cattle. E. esula can be controlled with chemical herbicides, but that approach can also kill harmless plants nearby. Recent research on introducing engineered DNA into plant species to inhibit their reproduction may offer a path toward exclusively targeting E. esula, consequently  

yellow, dotted = the words the question turns on · green, solid underline = the evidence that proves the answer · red, dashed = what pulls you toward a wrong choice

Correct: D) reducing invasive E. esula numbers without harming other organisms.
The passage sets up a problem with exactly two halves. Leafy spurge is harmful, and the current fix — herbicide — also kills harmless plants nearby. The new research promises a method that targets E. esula "exclusively." The word "consequently" means the ending states what that buys you: fewer spurge plants, and no damage to anything else. D says both halves.

A) making individual E. esula plants more susceptible to existing chemical herbicides. — wrong-relationship. The engineered-DNA method is presented as an alternative to herbicides, not as a way of making herbicides work better. A keeps the very approach the passage criticises.

B) enhancing the ecological benefits of E. esula in North America. — opposite. E. esula is described as invasive, displacing native plants and sickening cattle. Enhancing its ecological benefits reverses the whole passage.

C) enabling cattle to consume E. esula without becoming sick. — half-right. Sick cattle are one of the two named harms, so C feels close. But the research targets the plant’s reproduction, not its toxicity, and C ignores the "exclusively targeting" promise that the ending is built on.

The move — Finish the Logic Chain: "Consequently" is the same signal as "therefore" in different clothing. Name the two problems in the passage, then pick the ending that solves both. It fires whenever a completion blank follows a cause word. It saves you from the choice that fixes half the problem.
Also firing on this question: Read Past the Blank.

⚡ Shortcut: Count the complaints. This passage lists two: spurge is harmful, and the cure harms bystanders. Only one choice answers both, and that is almost always the pattern on completion items.

Standard English Conventions — questions 16 to 20

Five grammar questions in a row. Four are boundaries between clauses; one is apostrophes.

Question 16, Module 1 — Standard English Conventions: Boundaries (Easy)

I do — watch me work it

Five grammar questions now run back to back, and four of them are about boundaries between clauses. I model the test that solves them.

yellow, dotted = the dependent half, which cannot stand alone · green, solid underline = the independent half, which can

Which choice completes the text so that it conforms to the conventions of Standard English?

1. A) lifelike but
2. B) lifelike
3. C) lifelike,
4. D) lifelike, but

Question 17, Module 1 — Standard English Conventions: Boundaries (Medium)

We do — you make one call, then read on

The most-repeated punctuation heuristic on r/Sat is the semicolon-versus-period test. This item is where it earns its keep.

Which choice completes the text so that it conforms to the conventions of Standard English?

1. A) added, whenever
2. B) added; whenever
3. C) added. Whenever
4. D) added whenever

yellow, dotted = the words the question turns on · green, solid underline = the evidence that proves the answer

Question 18, Module 1 — Standard English Conventions: Form, Structure, and Sense (Hard)

Your turn — try it before you open the reasoning

The apostrophe item, and the hardest grammar question in the module. Reddit has a thread on this exact question — it is linked at the bottom of the page.

Which choice completes the text so that it conforms to the conventions of Standard English?

1. A) playas sediment mark the rock’s
2. B) playa’s sediment mark the rocks
3. C) playa’s sediment mark the rocks’
4. D) playas’ sediment mark the rocks’

Try it first — then open the reasoning

In Death Valley National Park’s Racetrack Playa, a flat, dry lakebed, are 162 rocks—some weighing less than a pound but others almost 700 pounds—that move periodically from place to place, seemingly of their own volition. Racetrack-like trails in the   mysterious migration.

yellow, dotted = the words the question turns on · green, solid underline = the evidence that proves the answer

Correct: C) playa’s sediment mark the rocks’
Two apostrophes, two separate decisions. First, how many playas? One — the passage names "Racetrack Playa," singular. Singular possessive is "playa’s." That kills A and D. Second, how many rocks? The passage says 162. Plural possessive is "rocks’," with the apostrophe after the s. Choice B has no apostrophe on "rocks" at all, which would make the migration belong to nobody. C is the only option with singular playa and plural-possessive rocks.

A) playas sediment mark the rock’s — wrong number on both. "Playas" is a plain plural where a possessive is needed, and "the rock’s" makes it one single rock. The passage gives 162 rocks and one playa, so A is wrong twice.

B) playa’s sediment mark the rocks — missing possessive. "Playa’s" is right. But "mark the rocks mysterious migration" has no possessive on "rocks," so the migration has no owner. Read it aloud and the sentence simply stops making sense.

D) playas’ sediment mark the rocks’ — wrong number. "Playas’" makes it several playas. The passage names one: Racetrack Playa. The second half of D is right, which is exactly what makes it tempting.

The move — Apostrophe Answers Two Questions: For every apostrophe, ask two things in this order. How many? Then, does it own something? One owner takes ’s. More than one owner takes s’. No ownership takes no apostrophe. It fires on any item where the choices differ only in apostrophes. It saves you from choosing by which one "looks normal."

⚡ Shortcut: When two apostrophes vary, split the four choices into a two-by-two grid. Settle the easier apostrophe first — here "playa," because the passage names it — and half the choices disappear at once.

⚠ Trap: Choice D gets "rocks’" right and only misses on "playas’." Half-right apostrophe choices are the standard trap on this question type, so check both apostrophes every time even after one clearly matches.

Question 19, Module 1 — Standard English Conventions: Boundaries (Medium)

Your turn — try it before you open the reasoning

Back to boundaries, this time with a colon in the mix.

Which choice completes the text so that it conforms to the conventions of Standard English?

1. A) photosynthesis and
2. B) photosynthesis,
3. C) photosynthesis:
4. D) photosynthesis

Try it first — then open the reasoning

Along with carbon dioxide concentration and temperature, light intensity affects the chemical reaction rate of photosynthesis   as light intensity increases, so does the rate at which the reactants (water and carbon dioxide) are converted into their products (glucose and oxygen).

green, solid underline = the evidence that proves the answer

Correct: C) photosynthesis:
Both halves are complete sentences. "Light intensity affects the chemical reaction rate of photosynthesis" stands alone. So does "as light intensity increases, so does the rate at which the reactants are converted into their products." The second half explains the first — it spells out how light intensity affects the rate. A colon is the mark for "here is the explanation," and it needs a complete sentence in front of it. That is C.

A) photosynthesis and — missing punctuation. "And" can join two complete sentences, but only with a comma before it. "Photosynthesis and as light intensity increases" has no comma and reads as a run-on.

B) photosynthesis, — comma splice. A lone comma between two complete sentences is a comma splice. This is the single most common wrong answer in this domain, and it is wrong every time.

D) photosynthesis — run-on. No punctuation at all fuses the two sentences. The reader cannot see where the first idea ends.

The move — Two Sentences or One: A colon needs a complete sentence before it and an explanation, list or example after it. It does not need a complete sentence after it, which is what separates it from the semicolon. It fires whenever a colon appears among the choices. It saves you from treating the colon and the semicolon as the same tool.
Also firing on this question: Read Past the Blank · Colon Means Proof Follows.

⚠ Trap: A comma alone can never join two complete sentences. Whenever both sides could be sentences on their own, cross out the bare-comma choice before you read anything else.

Question 20, Module 1 — Standard English Conventions: Boundaries (Medium)

Your turn — try it before you open the reasoning

The last grammar item. It looks like punctuation but it is really about whether a name is essential.

Which choice completes the text so that it conforms to the conventions of Standard English?

1. A) artists: Thomas Hart Benton and Jackson Pollock,
2. B) artists Thomas Hart Benton and Jackson Pollock
3. C) artists Thomas Hart Benton, and Jackson Pollock,
4. D) artists, Thomas Hart Benton and Jackson Pollock

Try it first — then open the reasoning

Paintings by the renowned twentieth-century US   were featured in Artist to Artist, an exhibition at the Smithsonian Art Museum that paired the works of artists whose career trajectories intersected in meaningful ways.

yellow, dotted = the words the question turns on · green, solid underline = the evidence that proves the answer

Correct: B) artists Thomas Hart Benton and Jackson Pollock
The names tell you which artists, so they are essential and take no punctuation separating them from "artists." The subject of the sentence is "Paintings by the renowned twentieth-century US artists Thomas Hart Benton and Jackson Pollock," and the verb "were featured" follows straight after. Any punctuation dropped into the middle of that subject cuts it in half. B leaves it whole.

A) artists: Thomas Hart Benton and Jackson Pollock, — wrong boundary mark. A colon needs a complete sentence in front of it. "Paintings by the renowned twentieth-century US artists" is a noun phrase with no verb, so nothing can follow a colon here. The trailing comma also separates the subject from its verb.

C) artists Thomas Hart Benton, and Jackson Pollock, — unnecessary comma. "Thomas Hart Benton, and Jackson Pollock" puts a comma in a two-item list, which never takes one. The comma after "Pollock" then cuts the subject off from "were featured."

D) artists, Thomas Hart Benton and Jackson Pollock — unnecessary comma. The comma after "artists" would signal that the names are extra information you could delete. Delete them and the sentence loses the point — you would not know whose paintings were shown.

The move — Two Sentences or One: When a name follows a job title or category word, test whether removing the name still leaves the sentence meaning what it meant. If it does not, the name is essential and takes no comma. It fires on names, titles and short labels. It saves you from sprinkling commas around every proper noun.
Also firing on this question: Essential Names Take No Comma.

⚡ Shortcut: Read the sentence with the choice in place and no other words. If the subject and its verb end up on opposite sides of a comma, that choice is out. Here "were featured" is the verb, and A, C and D all fence it off.

Expression of Ideas — questions 21 to 27

Seven questions to close the module. Three transitions, then four note-taking items in a block.

Question 21, Module 1 — Expression of Ideas: Transitions (Medium)

I do — watch me work it

The last seven questions are Expression of Ideas: three transitions, then four note-taking items. I model the transition method here.

green, solid underline = the evidence that proves the answer

Which choice completes the text with the most logical transition?

1. A) Fittingly,
2. B) Similarly,
3. C) However,
4. D) In other words,

Question 22, Module 1 — Expression of Ideas: Transitions (Easy)

We do — you make one call, then read on

The clearest transition item in the module. Make the call, then check it.

Which choice completes the text with the most logical transition?

1. A) In other words,
2. B) Therefore,
3. C) Likewise,
4. D) Nevertheless,

green, solid underline = the evidence that proves the answer · red, dashed = what pulls you toward a wrong choice

Question 23, Module 1 — Expression of Ideas: Transitions (Medium)

Your turn — try it before you open the reasoning

The last transition. Two of the choices are very close, so the method matters more than instinct.

Which choice completes the text with the most logical transition?

1. A) Similarly,
2. B) Finally,
3. C) Therefore,
4. D) Specifically,

Try it first — then open the reasoning

In his 1925 book The Morphology of Landscape, US geographer Carl Sauer challenged prevailing views about how natural landscapes influence human cultures.   Sauer argued that instead of being shaped entirely by their natural surroundings, cultures play an active role in their own development by virtue of their interactions with the environment.

yellow, dotted = the words the question turns on · green, solid underline = the evidence that proves the answer

Correct: D) Specifically,
Sentence one is general: Sauer challenged the usual view. Sentence two is the detail: here is exactly what he argued instead. Going from a general statement to its specific content is what "Specifically" marks. Notice the second sentence adds no new event — it spells the first one out.

A) Similarly, — wrong-relationship. "Similarly" needs two comparable things. There is only one thing here, described twice at different zoom levels.

B) Finally, — wrong-relationship. "Finally" marks the last item in a sequence. No sequence has been started — sentence two is the first detail, not the last of several.

C) Therefore, — reversed cause. "Therefore" would make Sauer’s argument a consequence of his having challenged the prevailing view. His argument is the challenge, not its result.

The move — Name the Turn: Watch the zoom level. If sentence two is a close-up of sentence one, you want "Specifically" or "For example." If it is a new step, you want "Then" or "Next." If it is a consequence, you want "Therefore." It fires on any transition where two choices both feel possible. It saves you the coin flip.

⚠ Trap: "Therefore" is the default guess and it is wrong here. Before choosing it, check that the second sentence really is caused by the first, not just a fuller version of it.

Question 24, Module 1 — Expression of Ideas: Rhetorical Synthesis (Easy)

Your turn — try it before you open the reasoning

Four note-taking questions close the module. The notes are the stimulus, so they get annotated like any passage.

The student wants to indicate where the dicraeosaurid fossil was found. Which choice most effectively uses relevant information from the notes to accomplish this goal?

1. A) The dicraeosaurid fossil was found in western India’s Thar Desert.
2. B) Bajpai’s team recently found the oldest dicraeosaurid fossil ever recovered.
3. C) Dr. Sunil Bajpai, of the Indian Institute of Technology, is part of a research team.
4. D) The fossil, which is from the dicraeosaurid dinosaur group, is 167 million years old.

Try it first — then open the reasoning

While researching a topic, a student has taken the following notes:

• Dr. Sunil Bajpai studies dinosaurs at the Indian Institute of Technology.
• Bajpai’s research team recently found a 167-million-year-old dicraeosaurid fossil.
• It is the oldest fossil from the dicraeosaurid dinosaur group ever recovered.
• It was found in the Thar Desert in western India.

green, solid underline = the evidence that proves the answer

Correct: A) The dicraeosaurid fossil was found in western India’s Thar Desert.
The goal is one word long: where. Only one note answers a where question — the Thar Desert in western India — and only one choice uses it. A gives the place and nothing but the place. Every other choice is a true sentence built from the notes, which is exactly why they are dangerous.

B) Bajpai’s team recently found the oldest dicraeosaurid fossil ever recovered. — true-but-off-goal. True, and it uses the notes correctly. But "oldest ever recovered" answers how old, not where. Accuracy is not the test here; the goal is.

C) Dr. Sunil Bajpai, of the Indian Institute of Technology, is part of a research team. — true-but-off-goal. True again, and it names the institution. An institution is where the scientist works, not where the fossil was dug up.

D) The fossil, which is from the dicraeosaurid dinosaur group, is 167 million years old. — true-but-off-goal. Also true, and also about age. Three of the four choices are correct statements. That is the standard design of this question type.

The move — Answer the Goal, Not the Notes: Underline the goal in the stem before you read the notes, then cross out every choice that does not do that exact job — even the true ones. It fires on every "the student wants to…" item. It saves you from the three accurate distractors this question type always carries.
Also firing on this question: True About the Text Is Not the Same as Right.

⚡ Shortcut: Reduce the goal to one question word: where, why, how old, how many. Then scan the four choices for the one that answers it. On this item that takes about eight seconds.

Question 25, Module 1 — Expression of Ideas: Rhetorical Synthesis (Medium)

Your turn — try it before you open the reasoning

Same skill, sharper goal. The word "reason" is doing all the work in the stem.

The student wants to specify the reason the Pleiades’ appearance changed. Which choice most effectively uses relevant information from the notes to accomplish this goal?

1. A) Ancient Native American and Australian Aboriginal cultures described the Pleiades, which was referred to in Greek mythology as the Seven Sisters, as having seven stars.
2. B) Although once referred to as the Seven Sisters, the Pleiades appears to have only six stars today.
3. C) In the time since ancient cultures described the Pleiades as having seven stars, two of the cluster’s stars have moved so close together that they now appear as one.
4. D) The Pleiades has seven stars, but two are so close together that they appear to be a single star.

Try it first — then open the reasoning

While researching a topic, a student has taken the following notes:

• Ancient Native American and Australian Aboriginal cultures described the Pleiades star cluster as having seven stars.
• It was referred to as the Seven Sisters in the mythology of ancient Greece.
• Today, the cluster appears to have only six stars.
• Two of the stars have moved so close together that they now appear as one.

green, solid underline = the evidence that proves the answer

Correct: C) In the time since ancient cultures described the Pleiades as having seven stars, two of the cluster’s stars have moved so close together that they now appear as one.
The goal asks for the reason the look of the cluster changed. Only the fourth note gives a cause: two stars have drifted so close that they now read as one. C states that cause and anchors it in time — "in the time since ancient cultures described the Pleiades as having seven stars" — so the reader can see the change and its cause together.

A) Ancient Native American and Australian Aboriginal cultures described the Pleiades, which was referred to in Greek mythology as the Seven Sisters, as having seven stars. — true-but-off-goal. It packs three notes into one sentence and reports the old count and the Greek name. It never says why anything changed.

B) Although once referred to as the Seven Sisters, the Pleiades appears to have only six stars today. — half-right. It shows the change — seven then, six now — which is half the job. It gives no cause at all, and the goal asked for the reason.

D) The Pleiades has seven stars, but two are so close together that they appear to be a single star. — contradicts the notes. "The Pleiades has seven stars" states the present tense of a fact the notes place in the past. The notes say it appears to have six today. D also skips the change entirely.

The move — Answer the Goal, Not the Notes: When the goal contains the word "reason," "cause," "why" or "because," hunt the one note that explains something rather than reporting it. The other notes are facts; you want the mechanism. It fires on any goal asking for a cause. It saves you from the neat summary sentence that explains nothing.

⚠ Trap: Choice B reads well and uses "Although," which makes it feel analytical. Fluent writing is not the standard on these items. Only the goal is.

Question 26, Module 1 — Expression of Ideas: Rhetorical Synthesis (Medium)

Your turn — try it before you open the reasoning

A goal word that trips a lot of students: "emphasize the significance."

The student wants to emphasize the significance of Ochoa’s discovery. Which choice most effectively uses relevant information from the notes to accomplish this goal?

1. A) Ochoa’s 1955 discovery of PNPase proved critical to deciphering the human genetic code, leading to a better understanding of how genetic variations affect human health.
2. B) Ochoa first discovered PNPase, an enzyme that he hypothesized contained the genetic blueprints for mRNA, in 1955.
3. C) In 1955, Ochoa discovered the PNPase enzyme, which is involved in both the creation and degradation of mRNA.
4. D) Though his discovery of PNPase was critical to deciphering the human genetic code, Ochoa incorrectly hypothesized that the enzyme was the source of mRNA’s genetic blueprints.

Try it first — then open the reasoning

While researching a topic, a student has taken the following notes:

• Severo Ochoa discovered the enzyme PNPase in 1955.
• PNPase is involved in both the creation and degradation of mRNA.
• Ochoa incorrectly hypothesized that PNPase provides the genetic blueprints for mRNA.
• The discovery of PNPase proved critical to deciphering the human genetic code.
• Deciphering the genetic code has led to a better understanding of how genetic variations affect human health.

green, solid underline = the evidence that proves the answer · red, dashed = what pulls you toward a wrong choice

Correct: A) Ochoa’s 1955 discovery of PNPase proved critical to deciphering the human genetic code, leading to a better understanding of how genetic variations affect human health.
"Significance" means how much it mattered and how far it reached. The last two notes form a chain: the discovery was critical to cracking the genetic code, and cracking the code improved our understanding of human health. Choice A follows that chain all the way to the human-health payoff. It is the only choice that leaves the laboratory.

B) Ochoa first discovered PNPase, an enzyme that he hypothesized contained the genetic blueprints for mRNA, in 1955. — true-but-off-goal. It reports the discovery and the hypothesis. The hypothesis was wrong, so leading with it does the opposite of emphasising importance.

C) In 1955, Ochoa discovered the PNPase enzyme, which is involved in both the creation and degradation of mRNA. — true-but-off-goal. It gives the date and what the enzyme does. That is description, not significance. Nothing here tells the reader why anyone should care.

D) Though his discovery of PNPase was critical to deciphering the human genetic code, Ochoa incorrectly hypothesized that the enzyme was the source of mRNA’s genetic blueprints. — half-right. D contains the significance — "critical to deciphering the human genetic code" — but buries it in a "Though" clause and gives the main clause to Ochoa’s mistake. Sentence structure decides what gets emphasised, and D emphasises the error.

The move — Answer the Goal, Not the Notes: When the goal is to emphasise something, check which idea sits in the main clause of each choice. A "Though…" or "Although…" opener demotes whatever follows it. It fires on every "emphasize" goal. It saves you from a choice that contains the right fact in the wrong grammatical slot.

⚡ Shortcut: "Significance" usually means "follow the chain to the end." Find the note furthest downstream — here, human health — and pick the choice that reaches it.

Question 27, Module 1 — Expression of Ideas: Rhetorical Synthesis (Hard)

Your turn — try it before you open the reasoning

The last question of Module 1, and the only one on the page with two goals in one stem. That is what makes it hard.

The student wants to emphasize the decline in unique apple varieties in the US and specify why this decline occurred. Which choice most effectively uses relevant information from the notes to accomplish these goals?

1. A) The Lost Apple Project is dedicated to finding some of the apple varieties lost following a shift in agricultural practices in the mid-1900s.
2. B) While over 14,000 apple varieties were grown in the US in the late 1890s, only 15 unique varieties make up most of the apples sold today.
3. C) Since the rise of industrial agriculture, US farmers have mainly grown the same few unique apple varieties, resulting in the loss of thousands of varieties less suitable for commercial growth.
4. D) As industrial agriculture rose to prominence in the mid-1900s, the number of crops selected for cultivation decreased dramatically.

Try it first — then open the reasoning

While researching a topic, a student has taken the following notes:

• In the late 1890s, over 14,000 unique varieties of apples were grown in the US.
• The rise of industrial agriculture in the mid-1900s narrowed the range of commercially grown crops.
• Thousands of apple varieties considered less suitable for commercial growth were lost.
• Today, only 15 apple varieties dominate the market, making up 90% of apples purchased in the US.
• The Lost Apple Project, based in Washington State, attempts to find and grow lost apple varieties.

green, solid underline = the evidence that proves the answer · red, dashed = what pulls you toward a wrong choice

Correct: C) Since the rise of industrial agriculture, US farmers have mainly grown the same few unique apple varieties, resulting in the loss of thousands of varieties less suitable for commercial growth.
Two goals, joined by "and," so the right answer has to do both. Goal one: show the decline. Goal two: say why it happened. C does both in one sentence — industrial agriculture pushed farmers toward a few varieties (the cause), which resulted in thousands of varieties being lost (the decline). The word "resulting in" is the join that carries the second goal.

A) The Lost Apple Project is dedicated to finding some of the apple varieties lost following a shift in agricultural practices in the mid-1900s. — true-but-off-goal. It is about a rescue project, not about the decline itself. It gestures at a cause — "a shift in agricultural practices" — but the subject of the sentence is the Lost Apple Project.

B) While over 14,000 apple varieties were grown in the US in the late 1890s, only 15 unique varieties make up most of the apples sold today. — half-right. B nails goal one. Fourteen thousand down to fifteen is the decline in the clearest numbers on the page. But it never says why, so it fails goal two. This is the choice most students pick.

D) As industrial agriculture rose to prominence in the mid-1900s, the number of crops selected for cultivation decreased dramatically. — scope shift. D gives a cause and a decline, but the decline it describes is in "crops" generally, not in apple varieties. The stem asked about apples specifically.

The move — Answer the Goal, Not the Notes: Read the goal sentence and count the verbs joined by "and." Two goals means two boxes to tick, and a choice that ticks one beautifully still loses to a choice that ticks both. It fires on any stem with "and" in the goal. It saves you from the strongest-sounding half answer. Count the Goals is the habit: mark the number in the margin before you look at the choices.
Also firing on this question: Count the Goals.

⚠ Trap: Choice B is the trap the whole item is built around. It carries the most memorable numbers on the page, so it feels like the point. Numbers are not the goal; the goal is the goal.

Rules and shortcuts from this test

Ten rules earned by the questions above. Each one names when it fires, what you do, and what it saves you. The names are the same ones printed in the blue box on each question, so you can jump back to the item that taught it.

1. Fill the Blank Yourself — taught by Questions 1–5. It fires on any stem asking for the most logical and precise word. You cover the choices and say your own word first. It saves you from the choice that sounds academic but does not fit, which is how most vocabulary points get lost.
2. Find the Echo Word — taught by Questions 1, 3, 4 and 5. It fires when a semicolon, colon or dash sits near the blank. You read the other half of the sentence, because it restates the missing word in different language. It saves about fifteen seconds an item, and on question 4 the echo — “calmer waters” — is literally the definition of the answer.
3. Purpose Is the Whole Text — taught by Questions 6 and 7. It fires on any main-purpose or main-idea stem. You check each choice against the first sentence and the last sentence together. It saves you from the choice built out of one vivid detail, which is how question 6 catches people with “a famous dancer.”
4. Agree Means Both Texts Say It — taught by Question 8. It fires on a dual-text item. You summarise each text in one word and keep only what sits inside both. It saves you from a choice that quotes Text 1 perfectly and has nothing to do with Text 2.
5. The Main Idea Owns the Last Sentence — taught by Questions 9 and 10. It fires on central-idea stems. You read sentence one for the subject and the last sentence for the point. It saves you a full re-read, and on question 10 the last sentence is the only place the answer lives.
6. Read the Axis First — taught by Question 13. It fires the moment a graph or table appears. You read the axis numbers and the legend, then say one bar aloud as a full sentence. It saves you from choices describing a bar that is not there, and it is the only way to check a value against a printed scale.
7. Finish the Logic Chain — taught by Questions 14 and 15. It fires when a completion blank follows “therefore” or “consequently.” You list the facts stacked above the blank and pick the ending that uses all of them. It saves you from a choice that restates one fact instead of finishing the argument.
8. Two Sentences or One — taught by Questions 16, 17, 19 and 20. It fires on every punctuation item. You test whether each side of the blank could stand alone, then check whether a connector like “while” is already doing the joining. It saves you from picking by ear, which fails as soon as the sentence gets long.
9. Name the Turn — taught by Questions 21, 22 and 23. It fires on every transition item. You cover the blank, read the two sentences as bare facts, and name the link in one word before looking at the choices. It saves you from “Therefore,” which is the most-picked wrong transition on this test and is wrong on question 23.
10. Answer the Goal, Not the Notes — taught by Questions 24, 25, 26 and 27. It fires on every “the student wants to…” stem. You underline the goal and cross out every choice that does not do that exact job, including the accurate ones. It saves you the four hardest points on the page, because three of the four choices are always true.

Cheat sheet — screenshot this

Rule (and the questions that taught it)	When it fires	What you do
Fill the Blank Yourself (Q1, Q2, Q3, Q4, Q5)	Any stem asking for “the most logical and precise word or phrase.”	Cover the choices, say your own word in the blank, then pick the closest match.
Find the Echo Word (Q1, Q3, Q4, Q5)	The blank sits near a semicolon, colon or dash.	Read the other half of the sentence for the word that restates the blank.
Read Past the Blank (Q2, Q5, Q14, Q15, Q19, Q22)	The blank falls in the middle of a sentence.	Finish the sentence before you choose; the words after the blank are evidence.
Colon Means Proof Follows (Q1, Q5, Q19)	A colon appears in the passage or among the choices.	Read what comes after the colon first — it defines or proves what came before.
Purpose Is the Whole Text (Q6, Q7)	The stem says “main purpose” or “main idea.”	Check the choice against the first sentence and the last sentence, not the most vivid detail.
Name What the Speaker Is Doing (Q7)	A literature passage with an old or difficult vocabulary.	Say the speaker’s action in one verb — reassuring, refusing, boasting — then match a choice to it.
Agree Means Both Texts Say It (Q8)	A two-text item asking what both authors would agree with.	Summarise each text in one word and pick only what sits inside both.
The Main Idea Owns the Last Sentence (Q9, Q10)	A central-idea or “best describes” stem.	Read sentence one and the final sentence first; the point almost always lands at the end.
Check the Strongest Word (Q10, Q13)	A choice contains “entirely,” “most effective,” “only” or “unsustainable.”	Ask whether the passage earned that word. Usually it did not.
Support Means the Prediction Comes True (Q11)	The stem asks which finding would support or weaken an idea.	Write the idea as an if…then sentence, then match the “then” half.
A Quotation Must Show, Not Tell (Q12)	Four quotations under a claim.	Split the claim into its parts and test each quotation against all of them.
Read the Axis First (Q13)	The stimulus includes a graph or a table.	Read the axis labels and legend, then say one bar out loud as a full sentence before touching the choices.
Weaken Means Find the Other Cause (Q13)	A conclusion blames one cause for a result.	Look in the control group — the column where the blamed cause is absent.
Finish the Logic Chain (Q14, Q15)	A completes-the-text blank sits after a result word — therefore, thus, so, consequently — anywhere in its clause.	List the facts stacked above the blank and pick the ending that uses all of them.
Two Sentences or One (Q16, Q17, Q19, Q20)	The four choices differ only in punctuation.	Test whether each side of the blank could stand alone, then check for a connector already doing the joining.
Apostrophe Answers Two Questions (Q18)	The choices differ in apostrophes.	For each word ask how many, then ask whether it owns something. One owner takes ’s, several take s’.
Essential Names Take No Comma (Q20)	A name follows a job title or category word.	Delete the name. If the sentence loses its meaning, the name is essential and takes no comma.
Name the Turn (Q21, Q22, Q23)	Any transition question.	Cover the blank, read both sentences as facts, and name the link in one word: same, opposite, result, example, restatement.
Answer the Goal, Not the Notes (Q24, Q25, Q26, Q27)	The stem starts “The student wants to…”	Underline the goal and cross out every choice that does not do that exact job, including the true ones.
Count the Goals (Q27)	The goal sentence joins two aims with “and.”	Mark the number of goals in the margin; a choice must tick both boxes to win.
