How to use this page. Every passage, question and answer choice below is quoted from the test itself, and the explanations are ours. Read the clean passage, pick your answer, and only then open the reasoning. The answer-key recap sits near the bottom if you only came for the letters.

Part 1 — Boundaries (10 items)

A Boundaries question hands you four choices that differ only in punctuation. The test is not asking what sounds right. It is asking where one sentence ends and the next begins.

⚡ Shortcut: The Punctuation Ladder. Before you read a single choice for meaning, sort the four marks by strength. Period and semicolon are full stops. A colon is a half stop, a comma is a pause, and no mark is no boundary. Two choices on the same rung usually cancel each other out, because the test never gives you two right answers.

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

I do — watch me work this one

While many video game creators strive to make their graphics ever more others look to the past, developing titles with visuals inspired by the “8-bit” games of the 1980s and 1990s. (The term “8-bit” refers to a console whose processor could only handle eight bits of data at once.)

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

A) lifelike but
B) lifelike
C) lifelike,
D) lifelike, but

What actually changes. Only the punctuation and the connector move. Here is the whole difference, mark by mark.

Choice	Mark used	Connector word	Boundary strength
A	no mark	but	none
B	no mark	none	none
C	, comma	none	pause
D	, comma	but	pause

While many video game creators strive to make their graphics ever more lifelike, others look to the past, developing titles with visuals inspired by the “8-bit” games of the 1980s and 1990s. (The term “8-bit” refers to a console whose processor could only handle eight bits of data at once.)

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it

Note → “While” is a subordinating conjunction. It turns everything after it into a dependent clause, one that cannot stand alone as a sentence.

Correct: C) lifelike,
Apply The Two-Clause Test: cover the blank and read each side alone. The left side is not a sentence, because “While” leaves it hanging. The right side, “others look to the past”, is one. Dependent clause first, independent clause second, comma between them, which is the pause rung on The Punctuation Ladder.

A) lifelike but — double connector. “While” already signals the contrast. Adding “but” stacks a second connector on the same joint, and the sentence loses its main clause.

B) lifelike — no boundary at all. The dependent clause runs straight into “others look to the past” with nothing between them. A reader cannot tell where the setup ends.

D) lifelike, but — double connector again. The comma is right. The word “but” is the problem, for the same reason it sinks A.

The move: when a sentence opens with While, Although, Because, If, When, or Since, put the comma where that opening clause ends. No second connector is allowed.

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

We do — you make one call, then I show you

As British scientist Peter Whibberley has observed, “the Earth is not a very good timekeeper.” Earth’s slightly irregular rotation rate means that measurements of time must be periodically adjusted. Specifically, an extra “leap second” (the 86,401st second of the day) is time based on the planet’s rotation lags a full nine-tenths of a second behind time kept by precise atomic clocks.

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

A) added, whenever
B) added; whenever
C) added. Whenever
D) added whenever

Your call before you read on: read the words from “whenever” to the end of the passage. Can they stand alone as their own sentence? Decide yes or no now.

What actually changes. Four different rungs of the ladder, one connector word that never moves.

Choice	Mark used	Boundary strength
A	, comma	pause
B	; semicolon	full stop
C	. period	full stop
D	no mark	none

As British scientist Peter Whibberley has observed, “the Earth is not a very good timekeeper.” Earth’s slightly irregular rotation rate means that measurements of time must be periodically adjusted. Specifically, an extra “leap second” (the 86,401st second of the day) is added whenever time based on the planet’s rotation lags a full nine-tenths of a second behind time kept by precise atomic clocks.

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it · red, dashed = what pulls you to a wrong choice

Correct: D) added whenever
The red stretch looks like a sentence, and that is the pull. It is not one, because “whenever” is a glue word. Glue Words Take No Comma, so when a whenever, when, because, if or although clause comes second, no mark goes in front of it. Run The Two-Clause Test and only the green stretch stands alone.

A) added, whenever — unnecessary pause. The comma marks the timing clause as an extra aside. It is not extra. It states the one condition that triggers the leap second.

B) added; whenever — wrong strength. A semicolon demands a full sentence on both sides. What follows is a dependent clause, so the right side comes up short.

C) added. Whenever — fragment. The period is the same strength as the semicolon in B, so both fail together. It leaves “Whenever time…clocks.” standing alone as a fragment.

The move: when B and C are the same rung of the ladder, cross out both. The test cannot key two choices that punctuate identically, so the answer is always among the rest.

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

Your turn — try it before you open the reasoning

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

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

A) photosynthesis and
B) photosynthesis,
C) photosynthesis:
D) photosynthesis

Try it first — then open the reasoning

Both halves are complete sentences. Only one mark on The Punctuation Ladder can join two complete sentences and promise that the second one explains the first.

D	no mark	none

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).

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it

Note → The second half does not add a new fact. It spells out what “light intensity affects the reaction rate” means in practice. That is the job a colon advertises.

Correct: C) photosynthesis:
Run The Two-Clause Test: both green stretches stand alone. Now apply The Colon Needs a Full Sentence in Front. A colon is legal only when the words to its left already make a complete sentence, and it signals that what follows explains or lists. Both conditions hold here.

A) photosynthesis and — run-on. “And” can join two sentences, but only with a comma in front of it. Bare, it fuses them.

B) photosynthesis, — comma splice. A comma is a pause, not a stop. It cannot hold two complete sentences apart on its own.

D) photosynthesis — fused sentence. No mark, no connector, two sentences jammed together. This is the same failure as A minus the word “and”.

The move: check that the first half is already a sentence. If the second half explains it rather than adding to it, reach for the colon.

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

Your turn — try it before you 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.

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

A) artists: Thomas Hart Benton and Jackson Pollock,
B) artists Thomas Hart Benton and Jackson Pollock
C) artists Thomas Hart Benton, and Jackson Pollock,
D) artists, Thomas Hart Benton and Jackson Pollock

Try it first — then open the reasoning

Find the verb of the main sentence, then find its subject. Nothing is allowed to sit between them.

What actually changes. Two slots can take a mark here: right after “artists”, and right before “were”.

Choice	After “artists”	Before “were”
A	: colon	, comma
B	no mark	no mark
C	no mark, but a , before “and”	, comma
D	, comma	no mark

Paintings by the renowned twentieth-century US artists Thomas Hart Benton and Jackson Pollock 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 spot the question turns on · green, solid = the evidence that decides it · red, dashed = what pulls you to a wrong choice

Correct: B) artists Thomas Hart Benton and Jackson Pollock
The subject is “Paintings” and the verb is “were featured”. Everything between them is one describing phrase, and nothing may cut it off from the verb, so the trailing comma in A and C dies. Then apply Name Tags Get No Commas: a job title is often followed by the specific names it points to. When those names are needed to say which ones, no punctuation goes between them.

A) artists: Thomas Hart Benton and Jackson Pollock, — illegal colon. “Paintings by the renowned twentieth-century US artists” is not a sentence, so nothing earns a colon. The trailing comma then splits subject from verb.

C) artists Thomas Hart Benton, and Jackson Pollock, — false list. Two items joined by “and” take no comma. The second comma splits subject from verb, exactly as in A.

D) artists, Thomas Hart Benton and Jackson Pollock — half an aside. One comma opens an interruption that never closes. If the names were truly extra, they would need a comma on each side.

The move: locate the main verb first. If a choice puts a mark immediately before it, delete that choice without further thought.

Question 18, Module 2 (easier branch) — Standard English Conventions: Boundaries (Medium)

Your turn — try it before you open the reasoning

After the United Kingdom began rolling out taxes equivalent to a few cents on single-use plastic grocery bags in 2011, plastic-bag consumption decreased by up to ninety taxes are subject to what economists call the “rebound effect”: as the change became normalized, plastic-bag use started to creep back up.

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

A) percent, such
B) percent and such
C) percent. Such
D) percent such

Try it first — then open the reasoning

There is already a colon later in the sentence. That tells you the second half is doing its own work and does not need to be glued to the first.

What actually changes. Note that no choice offers a semicolon, which is unusual and worth seeing.

Choice	Mark used	Boundary strength
A	, comma	pause
B	no mark plus “and”	none
C	. period	full stop
D	no mark	none

After the United Kingdom began rolling out taxes equivalent to a few cents on single-use plastic grocery bags in 2011, plastic-bag consumption decreased by up to ninety percent. Such taxes are subject to what economists call the “rebound effect”: as the change became normalized, plastic-bag use started to creep back up.

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it · red, dashed = what pulls you to a wrong choice

Correct: C) percent. Such
Both green stretches are complete sentences, so The Two-Clause Test calls for a full stop, and only C supplies one. Here The Semicolon-Equals-Period Rule works in reverse. A semicolon would have been just as correct as this period, so the test could not offer one.

A) percent, such — comma splice. Two full sentences held apart by a pause. This is the single most common wrong answer on Boundaries items.

B) percent and such — run-on. “And” needs a comma in front when it joins two sentences. Bare, it fuses them.

D) percent such — fused sentence. Nothing marks the join at all, and “ninety percent such taxes” reads as one broken noun phrase.

The move: if the choice set contains a period but no semicolon, that is a tell. The test removed the twin so the full stop could be keyed.

Question 20, Module 2 (easier branch) — Standard English Conventions: Boundaries (Medium)

Your turn — try it before you open the reasoning

In February 1919, following the end of the First World War, women from ten countries around the world convened the Inter-Allied Women’s Conference in Paris. The conference’s goals were ensure women’s participation in the proceedings of the Paris Peace Conference, to secure the right of women to serve in the League of Nations, and to advocate for human rights.

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

A) threefold: to
B) threefold. To
C) threefold to
D) threefold; to

Try it first — then open the reasoning

Count the “to” phrases after the blank. The word “threefold” is a promise, and something has to deliver on it.

What actually changes. All four rungs appear once each.

Choice	Mark used	What that mark demands after it
A	: colon	an explanation or a list, sentence or not
B	. period	a complete sentence
C	no mark	nothing, so the list is never announced
D	; semicolon	a complete sentence

In February 1919, following the end of the First World War, women from ten countries around the world convened the Inter-Allied Women’s Conference in Paris. The conference’s goals were threefold: to ensure women’s participation in the proceedings of the Paris Peace Conference, to secure the right of women to serve in the League of Nations, and to advocate for human rights.

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it · red, dashed = what pulls you to a wrong choice

Note → The red stretch is three “to” phrases in a row. A string of phrases is not a sentence, however long it runs.

Correct: A) threefold: to
“The conference’s goals were threefold” is a complete sentence, which satisfies The Colon Needs a Full Sentence in Front. The word “threefold” announces a count, and the colon delivers the three items. On The Punctuation Ladder, the colon is the only rung that accepts a list rather than a sentence on its right.

B) threefold. To — fragment. A period demands a full sentence next. “To ensure…, to secure…, and to advocate for human rights.” has no subject and no main verb.

D) threefold; to — wrong strength. The semicolon makes the identical demand as the period in B, and the identical thing goes wrong. Two choices, one flaw.

C) threefold to — no boundary. Without a mark, “were threefold to ensure” reads as a purpose, so the promised count of three is never delivered.

The move: a counting word such as threefold, two, several, or the following is a colon flag. Look left, confirm a sentence, and take the colon.

Question 16, Module 2 (harder branch) — Standard English Conventions: Boundaries (Medium)

Your turn — try it before you open the reasoning

Stomata, tiny pore structures in a leaf that absorb gases needed for plant growth, open when guard cells surrounding each pore swell with water. In a pivotal 2007 article, plant cell showed that lipid molecules called phosphatidylinositol phosphates are responsible for signaling guard cells to open stomata.

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

A) biologist, Yuree Lee
B) biologist Yuree Lee,
C) biologist Yuree Lee
D) biologist, Yuree Lee,

Try it first — then open the reasoning

This is a four-way punctuation grid on a title-plus-name pair. Ask whether the name could be deleted without leaving the sentence vague.

What actually changes. The same two slots, filled four different ways.

Choice	After “biologist”	After “Lee”	What it claims
A	, comma	no mark	an aside that never closes
B	no mark	, comma	a pause between subject and verb
C	no mark	no mark	the name is needed, so nothing separates it
D	, comma	, comma	the name is removable extra

Stomata, tiny pore structures in a leaf that absorb gases needed for plant growth, open when guard cells surrounding each pore swell with water. In a pivotal 2007 article, plant cell biologist Yuree Lee showed that lipid molecules called phosphatidylinositol phosphates are responsible for signaling guard cells to open stomata.

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it

Correct: C) biologist Yuree Lee
Name Tags Get No Commas. “Plant cell biologist” is a job label, and “Yuree Lee” says which biologist. Delete the name and the sentence no longer identifies who did the work, so the name is essential, and essential means no commas. The Two-Clause Test confirms there is only one clause here, so no sentence boundary is in play.

A) biologist, Yuree Lee — half an aside. One comma opens an interruption and nothing closes it. Punctuation that comes in pairs must arrive in pairs.

B) biologist Yuree Lee, — subject cut from verb. The comma lands between “Yuree Lee” and “showed”. A subject is never separated from its verb by a single comma.

D) biologist, Yuree Lee, — false extra. The pair of commas is properly matched, so this one looks careful. It still claims the name is deletable, and it is not.

The move: delete the words between the commas and reread. If the sentence goes vague, the words are essential and the commas must come out.

Question 18, Module 2 (harder branch) — Standard English Conventions: Boundaries (Hard)

Your turn — try it before you open the reasoning

During the English neoclassical period (1660–1789), many writers imitated the epic poetry and satires of ancient Greece and Rome. They were not the first in England to adopt the literary modes of classical some of the most prominent figures of the earlier Renaissance period were also influenced by ancient Greek and Roman literature.

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

A) antiquity, however
B) antiquity, however,
C) antiquity, however;
D) antiquity; however,

Try it first — then open the reasoning

C and D use the same two marks in the opposite order. That swap decides which clause the word “however” belongs to, so work out which clause actually needs it.

What actually changes. The word “however” never moves. The marks around it do.

Choice	Before “however”	After “however”	Result
A	, comma	no mark	run-on
B	, comma	, comma	comma splice
C	, comma	; semicolon	“however” ends clause one
D	; semicolon	, comma	“however” starts clause two

During the English neoclassical period (1660–1789), many writers imitated the epic poetry and satires of ancient Greece and Rome. They were not the first in England to adopt the literary modes of classical antiquity, however; some of the most prominent figures of the earlier Renaissance period were also influenced by ancient Greek and Roman literature.

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it · red, dashed = what pulls you to a wrong choice

Note → The contrast is with the sentence before, which said writers imitated the classics. “They were not the first, however” pushes back on that. The red clause then supports the green one; it does not oppose it.

Correct: C) antiquity, however;
However Is Not a Glue Word. It cannot join two sentences, so a real boundary mark still has to appear somewhere. Here “however” points backward at the previous sentence, so it belongs to clause one. A comma tucks it in; a semicolon closes the clause. The Semicolon-Equals-Period Rule confirms the strength: swap in a period and the passage still reads correctly.

A) antiquity, however — run-on. Nothing separates the two sentences. The comma only fences off “however”.

B) antiquity, however, — comma splice. Two commas around “however” leave a pause where a stop is required.

D) antiquity; however, — right mark, wrong direction. The punctuation is legal, so this is the trap that catches strong students. It attaches “however” to the second clause, which does not contrast with the first; it agrees with it and adds “also”.

The move: when two choices use the same marks in swapped order, punctuation is no longer the question. Ask which clause the transition word is about.

Question 19, Module 2 (harder branch) — Standard English Conventions: Boundaries (Hard)

Your turn — try it before you open the reasoning

With the development of new technologies that use natural resources more efficiently, the overall consumption of those resources might be expected to decrease. Economists have observed that improvements in efficiency often correlate negatively with resource efficiency gains, lowering the cost of use, may increase demand to the extent that resource consumption ultimately rises.

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

A) conservation, though,
B) conservation; though
C) conservation, though;
D) conservation, though

Try it first — then open the reasoning

The word “though” has two jobs in English. It can act as a transition meaning “however”, or as a glue word meaning “although”. Which job is it doing here?

What actually changes. Same two slots as the last item, and the same swap trap.

Choice	Before “though”	After “though”	Result
A	, comma	, comma	comma splice
B	; semicolon	no mark	fragment after the semicolon
C	, comma	; semicolon	clean stop between two sentences
D	, comma	no mark	run-on

With the development of new technologies that use natural resources more efficiently, the overall consumption of those resources might be expected to decrease. Economists have observed that improvements in efficiency often correlate negatively with resource conservation, though; efficiency gains, lowering the cost of use, may increase demand to the extent that resource consumption ultimately rises.

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it · red, dashed = what pulls you to a wrong choice

Correct: C) conservation, though;
Both the green and the red stretch are full sentences, so The Two-Clause Test demands a stop. Here “though” means “however” and looks back at the expectation set in the first sentence, so it closes clause one. However Is Not a Glue Word covers “though” in this sense too. The Semicolon-Equals-Period Rule checks the work: put a period where the semicolon is and nothing breaks.

A) conservation, though, — comma splice. Commas on both sides of “though” leave two sentences joined by nothing but a pause.

B) conservation; though — fragment. Move “though” to the front of clause two and it becomes a glue word meaning “although”. Everything after the semicolon is then a dependent clause, and a semicolon cannot end there.

D) conservation, though — run-on. The comma handles “though” and nothing handles the sentence break.

The move: “though” at the end of a clause means however and needs a stop after it. “Though” at the start of a clause means although and makes that clause dependent.

No choice contains a punctuation mark, yet this is still a punctuation question. The comma before “its vehicles” is already printed in the passage and cannot be removed.

What actually changes. This is the one item on the page where the mark is fixed and the verb moves. Read the last column, not the middle one.

Choice	Mark inside the choice	Mark already in the passage	Does it create a second sentence?
A	no mark	, comma	yes, so it splices
B	no mark	, comma	yes, so it splices
C	no mark	, comma	no, it stays a phrase
D	no mark	, comma	yes, so it splices

In the late nineteenth and early twentieth centuries, automobiles were commonly referred to as horseless carriages after the older technology they still resembled. Known as the Brass Era, this period in automotive design is remembered for its grandeur and artistry, its vehicles highly prized by collectors for their ornate detailing and gleaming brass fittings.

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it · red, dashed = what pulls you to a wrong choice

Note → “Its vehicles highly prized by collectors” is a describing phrase hung off the main sentence. Grammar books call it an absolute phrase. It has a noun and a participle, but no working verb.

Correct: C) highly prized
The Comma-Plus-Verb Splice. A comma sits before “its vehicles” and you cannot delete it. Drop in a working verb and you have two sentences joined by a comma. Run The Two-Clause Test on choice C and the right side reads “its vehicles highly prized by collectors”, which cannot stand alone. That is what makes it legal.

A) are highly prized — comma splice. “Its vehicles are highly prized by collectors” is a complete sentence, and only a comma stands in front of it.

B) had been highly prized — comma splice plus a tense clash. It splices for the same reason as A, and the past perfect puts the collecting before a past event the passage never names.

D) were highly prized — comma splice. A and D differ only in tense, so they fail together. Two choices that fail for one shared reason can both be crossed out at once.

The move: when a comma is already printed and every choice is a verb form, the question is still Boundaries. Pick the form that refuses to make a second sentence.

⚠ Trap: students who study “punctuation questions” as a category miss this one, because the choices contain no punctuation. Judge the item by what the passage already prints, not by what the choices show you.

These seven ask a different question. Not where the sentence breaks, but which form of a word keeps the sentence working: which verb, which pronoun, which apostrophe.

Question 15, Module 2 (easier branch) — Standard English Conventions: Form, Structure, and Sense (Easy)

I do — watch me work this one

British scientists James Watson and Francis Crick won the Nobel Prize in part for their 1953 paper announcing the double helix structure of DNA, but it is misleading to say that Watson and Crick discovered the double helix. Their findings were based on a famous X-ray image of DNA fibers, “Photo 51,” developed by X-ray crystallographer Rosalind Franklin and her graduate student Raymond Gosling.

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it

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

A) They’re
B) It’s
C) Their
D) Its

What actually changes. The apostrophe is punctuation too, and here it flips a word from ownership into a hidden verb.

Choice	Mark used	What the word then means	Number
A	’ apostrophe	they are	plural
B	’ apostrophe	it is	singular
C	no mark	belonging to them	plural
D	no mark	belonging to it	singular

Correct: C) Their
Find the Real Subject of the new sentence: it is “findings”, and something has to own them. The owners are Watson and Crick, two people, so you need the plural possessive determiner. Match the Owner, Then the Thing: fix who owns it first, then fix the number. Two owners gives “Their”, and no apostrophe appears in any possessive pronoun.

A) They’re — contraction for a possessive. Expand it and you get “They are findings were based on…”, which has two verbs and no owner.

B) It’s — contraction, and singular. It breaks the sentence the same way A does. It also points at one thing when the passage names two scientists.

D) Its — right kind of word, wrong number. This is a genuine possessive with no apostrophe, so it survives the first filter. It refers to one owner, and there are two.

The move: read every apostrophe choice out loud as its full words. If “they are” or “it is” makes the sentence ungrammatical, that choice is gone before you think about meaning.

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

We do — you make one call, then I show you

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.

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

A) playas sediment mark the rock’s
B) playa’s sediment mark the rocks
C) playa’s sediment mark the rocks’
D) playas’ sediment mark the rocks’

Your call before you read on: the passage names how many playas, and how many rocks? Write both numbers down. Those two numbers decide the whole item.

What actually changes. Two apostrophe slots, each one carrying a count.

Choice	Playa slot	Rock slot	What it claims
A	no mark	’s	many playas own nothing, one rock owns the trails
B	’s	no mark	one playa owns the sediment, rocks own nothing
C	’s	s’	one playa, many rocks, both owning
D	s’	s’	many playas, many rocks

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it · red, dashed = what pulls you to a wrong choice

Note → The red word is the subject of “mark”. Trails is plural, so “mark” is right in all four choices. That is why the verb is not the deciding factor here.

Correct: C) playa’s sediment mark the rocks’
Match the Owner, Then the Thing. The passage names one playa, Racetrack Playa, so the sediment belongs to a single playa: apostrophe before the s. It names 162 rocks, and the migration belongs to all of them, so the apostrophe goes after the s. Both slots carry an owner, so both need a mark.

A) playas sediment mark the rock’s — both slots wrong. “Playas” is a bare plural that owns nothing, and “rock’s” drops 161 of the rocks.

B) playa’s sediment mark the rocks — half right. The first slot is correct and that is the pull. Without the second apostrophe the sentence reads “mark the rocks mysterious migration”, which owns nothing.

D) playas’ sediment mark the rocks’ — wrong count. The rock slot is right. The playa slot invents extra playas the passage never mentions.

The move: for each apostrophe slot, ask “how many owners does the passage actually name?” Before the s means one. After the s means more than one.

Question 17, Module 2 (easier branch) — Standard English Conventions: Form, Structure, and Sense (Medium)

Your turn — try it before you open the reasoning

In order to prevent nonnative fish species from moving freely between the Mediterranean and Red Seas, marine biologist Bella Galil has proposed that a saline lock system be installed along the Suez Canal in Egypt’s Great Bitter Lakes. The lock would increase the salinity of the lakes and a natural barrier of water most marine creatures would be unable to cross.

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

A) creates
B) create
C) creating
D) created

Try it first — then open the reasoning

No choice contains a punctuation mark, so there is nothing to diff. Look at the word “and” and at the verb on its left.

In order to prevent nonnative fish species from moving freely between the Mediterranean and Red Seas, marine biologist Bella Galil has proposed that a saline lock system be installed along the Suez Canal in Egypt’s Great Bitter Lakes. The lock would increase the salinity of the lakes and create a natural barrier of water most marine creatures would be unable to cross.

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it · red, dashed = what pulls you to a wrong choice

Correct: B) create
The Modal Carries Over. The lock “would increase” and “would create”. A modal such as would, will, can or might sits before the first verb. The second verb after “and” borrows it and stays in the base form. Say it with “would” repeated to hear it: would increase the salinity and would create a natural barrier.

A) creates — broken pairing. Adding the s makes it a present-tense verb of its own, which cannot share “would”. The sentence then says the lock would do one thing and does another.

C) creating — wrong form after “and”. An -ing word is not a verb that can pair with “would increase”. It turns the second half into a loose modifier hanging off nothing.

D) created — wrong time. The lock has not been built; the passage says it is proposed. A past-tense verb also cannot share “would”.

The move: when the blank sits after “and”, find the verb on the other side of the “and” and copy its shape, not its meaning.

Question 19, Module 2 (easier branch) — Standard English Conventions: Form, Structure, and Sense (Medium)

Your turn — try it before you open the reasoning

Food and the sensation of taste are central to Monique Truong’s novels. In The Book of Salt, for example, the exiled character of Bình connects to his native Saigon through the food he prepares, while in Bitter in the Mouth, the character of Linda a form of synesthesia whereby the words she hears evoke tastes.

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

A) experienced
B) had experienced
C) experiences
D) will be experiencing

Try it first — then open the reasoning

The sentence describes two novels side by side. Find the verb used for the first novel and match it.

Food and the sensation of taste are central to Monique Truong’s novels. In The Book of Salt, for example, the exiled character of Bình connects to his native Saigon through the food he prepares, while in Bitter in the Mouth, the character of Linda experiences a form of synesthesia whereby the words she hears evoke tastes.

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it · red, dashed = what pulls you to a wrong choice

Note → Writers describe what happens inside a book in the present tense, even for books written long ago. Three green verbs here are all present.

Correct: C) experiences
Tense Follows the Neighbours. Connects, prepares and hears are all present tense, and the blank does the same job in the same sentence, so it must be present too. Now Find the Real Subject: it is “the character”, not “Linda” and not “novels”. One character takes the singular verb “experiences”.

A) experienced — wrong tense. Past tense breaks the pairing with “connects” on the other side of “while”.

B) had experienced — wrong tense, extra claim. The past perfect says this happened before some other past moment. No such moment exists in the passage.

D) will be experiencing — wrong tense. The future turns a description of an existing novel into a prediction.

The move: circle every other verb in the same sentence first. On the Digital SAT the correct tense is almost always the one already on the page.

Question 20, Module 2 (harder branch) — Standard English Conventions: Form, Structure, and Sense (Medium)

Your turn — try it before you open the reasoning

The ghazal, a poetic form originating in seventh-century Arabic poetry, has an intricate structure. The twentieth-century Kashmiri American poet Agha Shahid Ali explains that each one of a ghazal’s couplets, while adhering to the patterns of rhyme (qafia) and refrain (radif) established in the poem’s opening lines (matla), thematically and logically autonomous, resulting in a poem with “a stringently formal disunity.”

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

A) is
B) were
C) have been
D) are

Try it first — then open the reasoning

Cross out everything between the two commas. Whatever is left in front of the blank is the subject.

The ghazal, a poetic form originating in seventh-century Arabic poetry, has an intricate structure. The twentieth-century Kashmiri American poet Agha Shahid Ali explains that each one of a ghazal’s couplets, while adhering to the patterns of rhyme (qafia) and refrain (radif) established in the poem’s opening lines (matla), is thematically and logically autonomous, resulting in a poem with “a stringently formal disunity.”

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it · red, dashed = what pulls you to a wrong choice

Correct: A) is
Find the Real Subject. Strip the aside between the commas and the subject is “each one”, which is always singular. “Couplets” is plural, but it sits inside “of”, and a noun inside an “of” phrase is never the subject. The neighbouring verb “explains” fixes the tense as present.

B) were — plural and past. It agrees with the red decoy “couplets” and it drops out of the present tense set by “explains”.

C) have been — plural. The present perfect also implies the state started earlier and may be over, which the passage never suggests.

D) are — plural. The tense is right, which is why this is the most tempting wrong answer. It still agrees with the decoy instead of with “each one”.

⚡ Shortcut: the words each, every, one, either and neither are singular no matter how many plural nouns follow them. Spot one and you can answer in five seconds.

Question 16, Module 2 (easier branch) — Standard English Conventions: Form, Structure, and Sense (Hard)

A member of the Cherokee Nation, Mary Golda Ross is renowned for her contributions to NASA’s Planetary Flight Handbook, which provided detailed mathematical guidance for missions to Mars and Venus.

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it · red, dashed = what pulls you to a wrong choice

Note → This is one of the two items on this form that sits on the line between the two sub-skills. The choice set is pure verb form, and no punctuation moves, so it is Form, Structure, and Sense, not Boundaries.

Correct: A) provided
Every Sentence Needs One Real Verb. “Which” is a relative pronoun acting as the subject of its own clause, and a subject needs a working verb. Only “provided” is one. The past tense is right because the Handbook was written and used in the past, while “is renowned” describes Ross's reputation now.

B) having provided — no working verb. “Having provided” is a participle phrase. It leaves “which” as a subject with nothing to do.

C) to provide — no working verb. An infinitive names an action without saying who does it or when. The clause stays unfinished.

D) providing — no working verb. B, C and D all fail for one shared reason. When three choices share a flaw, the fourth is your answer.

The move: after who, which, or that, the blank almost always wants a plain conjugated verb. Cross out every -ing and every “to” form on sight.

Question 15, Module 2 (harder branch) — Standard English Conventions: Form, Structure, and Sense (Hard)

Your turn — try it before you open the reasoning

In 1966, Emmett Ashford became the first African American to umpire a Major League Baseball game. His energetic gestures announcing when a player had struck out and his habit of barreling after a hit ball to see if it would land out of transform the traditionally solemn umpire role into a dynamic one.

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

A) bounds helped
B) bounds, helping
C) bounds that helped
D) bounds to help

Try it first — then open the reasoning

This sentence is 38 words long and has no verb yet. Find the subject, then ask which choice finally gives it one.

What actually changes. One choice carries a comma, and it is not the answer, so read the verb column.

Choice	Mark used	Word form supplied	Does the sentence get a main verb?
A	no mark	conjugated verb	yes
B	, comma	participle	no
C	no mark	relative clause	no
D	no mark	infinitive	no

In 1966, Emmett Ashford became the first African American to umpire a Major League Baseball game. His energetic gestures announcing when a player had struck out and his habit of barreling after a hit ball to see if it would land out of bounds helped transform the traditionally solemn umpire role into a dynamic one.

yellow, dotted = the spot the question turns on · green, solid = the evidence that decides it · red, dashed = what pulls you to a wrong choice

Note → The red verb belongs to the small clause “if it would land out of bounds”. Buried verbs like this one make a sentence feel finished when it is not.

Correct: A) bounds helped
Find the Real Subject first: it is the pair “His energetic gestures … and his habit …”. Then apply Every Sentence Needs One Real Verb. Everything printed so far is a modifier or a verb locked inside a smaller clause. The main verb must come from the blank, and “helped transform” supplies it. This is the second item on this form whose sub-skill is decided by verb form rather than by punctuation.

B) bounds, helping — fragment. The comma plus an -ing word makes a trailing description. The 38-word subject is left with nothing to do.

C) bounds that helped — fragment. “That helped transform…” describes the bounds. It buries the verb one level deeper instead of releasing it.

D) bounds to help — fragment. An infinitive states a purpose. B, C and D all leave the sentence without a main verb, so they fall together.

The move: on a long sentence, read the subject aloud and stop. If your voice is still waiting for something, the blank owes you a main verb.

Rules and shortcuts from this test

Ten rules, each earned from a question above. Each one says when it fires, what you do, and what it saves you.

1. The Two-Clause Test — from Module 1 questions 16, 17 and 19.
Fires when: the four choices differ in punctuation.
You do: cover the blank and read each side alone, asking whether it could be its own sentence.
Saves you: the entire comma-splice error class, which is the most common wrong answer on this form.

⚡ 2. The Punctuation Ladder — from Module 1 questions 16 and 19 and Module 2 easier-branch question 20.
Fires when: you first look at a Boundaries choice set.
You do: sort the marks by strength before reading for meaning.
Saves you: about 20 seconds an item, because two choices usually land on the same rung and cancel.

3. Glue Words Take No Comma — from Module 1 question 17.
Fires when: the blank sits in front of whenever, when, because, if, although, unless or since, and that clause comes second.
You do: take the choice with no mark.
Saves you: the habit of punctuating wherever you would pause when speaking.

4. The Colon Needs a Full Sentence in Front — from Module 1 question 19 and Module 2 easier-branch question 20.
Fires when: a colon appears among the choices.
You do: check only the words to the left; if they are not a sentence, the colon is dead.
Saves you: the trap in Module 1 question 20, where the colon looked plausible and was illegal.

5. Name Tags Get No Commas — from Module 1 question 20 and Module 2 harder-branch question 16.
Fires when: a job title or category label is followed by a specific name.
You do: delete the name and reread; if the sentence goes vague, use no commas.
Saves you: two items on this form and roughly one on every Digital SAT.

6. The Semicolon-Equals-Period Rule — from Module 2 easier-branch question 18 and Module 2 harder-branch questions 18 and 19.
Fires when: a semicolon and a period both appear in the choices.
You do: cross out both, because they do the same job and the test cannot key two right answers.
Saves you: half the choice set instantly. This is the elimination move students on r/Sat repeat most often.

7. However Is Not a Glue Word — from Module 2 harder-branch questions 18 and 19.
Fires when: however, though, therefore or in addition sits at the join.
You do: add a real stop anyway, then decide which clause the transition is about.
Saves you: the swapped-marks trap that makes these two the hardest Boundaries items on the form.

8. The Comma-Plus-Verb Splice — from Module 2 harder-branch question 17.
Fires when: a comma is already printed in the passage and every choice is a verb form.
You do: pick the form that will not build a second sentence.
Saves you: an item most students never even classify as punctuation.

9. Match the Owner, Then the Thing — from Module 2 easier-branch question 15 and Module 1 question 18.
Fires when: apostrophes move between choices.
You do: count the owners the passage names, then place the apostrophe before or after the s.
Saves you: the half-right trap, where one of the two apostrophe slots is correct and the other is not.

10. Every Sentence Needs One Real Verb — from Module 2 easier-branch question 16 and Module 2 harder-branch question 15.
Fires when: the choices are a conjugated verb plus an -ing form, a “to” form, and a “that” clause.
You do: read the subject aloud and stop; if your voice is still waiting, take the conjugated verb.
Saves you: the two hardest items on this page.

Questions students ask about this test

What grammar rules are tested on Bluebook test 10?

Ten of the 17 items are Boundaries: commas, semicolons, colons, periods and no-mark choices. The other seven are Form, Structure, and Sense: possessive apostrophes, subject-verb agreement, verb tense, and supplying a main verb. No item asks about spelling or word choice.

What are the answers to test 10 punctuation questions?

Module 1 runs C, D, C, C, B for questions 16 to 20. The easier Module 2 runs C, A, B, C, C, A for questions 15 to 20. The harder Module 2 runs A, C, C, C, C, A. The table above lays all 17 out side by side.

When do I use a colon versus a semicolon?

A semicolon needs a full sentence on both sides and joins two equal ideas. A colon needs a full sentence only on its left, and what follows explains or lists. Module 1 question 19 is the colon case; Module 2 harder-branch question 18 is the semicolon case.

What is a boundaries question on the Digital SAT?

It is an item whose four choices differ only in punctuation. The College Board groups it under Standard English Conventions. The skill being measured is whether you can tell a complete sentence from a fragment or a phrase.

Which grammar question on test 10 is hardest?

Module 2 harder-branch question 15, the Emmett Ashford item. The subject runs 38 words, and three of the four choices leave the sentence without a main verb. The buried verb “would land” makes it sound finished when it is not.

How many conventions questions are on the SAT?

On this form there are 17 across all three Reading and Writing modules, and that is the smallest of the four domains here. Module 1 carries five, and each Module 2 branch carries six. The count moves a little from form to form.

How do I catch modifier errors fast?

Test 10 does not include a classic dangling-modifier item, but it does include describing phrases that pretend to be clauses. Module 2 harder-branch question 17 is the one to study. Cover the phrase, check that a real sentence remains, and put it back.

Which grammar rules show up on every practice test?

The comma splice, the semicolon-equals-period elimination, the essential-versus-extra comma pair, and subject-verb agreement across a long phrase. All four appear on this form more than once. Learn those and you cover most of the domain.
