Question 9: Analyzing M. robustus

Question

Which statement about M. robustus and the Octopus Garden is best supported by the text?

Text

In 2018, scientists discovered an immense aggregation of M. robustus (Muusoctopus robustus) (pearl octopuses) along a hydrothermal vent 3,200 meters beneath the ocean’s surface. Water temperatures at this site—named the Octopus Garden—climb as high as 11°C, much warmer than the ambient 1.6°C typical at this depth. Based on observations made over three years, scientists concluded that temperatures at the site likely confer reproductive benefits and that the site is used exclusively for reproduction—6,000 M. robustus adults, hatchlings, and eggs were observed at the garden, but no juveniles were present.

Answer Choices

(A) M. robustus leave the Octopus Garden upon reaching an intermediary stage of development.
(B) The M. robustus population at the Octopus Garden remains stable despite variations in water temperature.
(C) M. robustus nests in the Octopus Garden contain on average fewer but larger eggs than nests at similar ocean depths.
(D) The Octopus Garden provides an ideal feeding ground for M. robustus hatchlings.

Explanation

Think like a detective! We need the statement most strongly supported by the clues (the text).

Key Clues: The Octopus Garden is warmer (11°C vs 1.6°C) and seems to be *just* for breeding. They found adults, eggs, and newborns (hatchlings), but no juveniles (the 'teenager' octopuses).
Challenge Check: Does understanding subtle implications like this trip you up? Quality sat exam coaching, like our self-paced platform, helps build these analytical skills.

Why Option A is Correct:

The text explicitly says: "...no juveniles were present." If eggs hatch but the next stage isn't there, they must have moved out! Option A describes this exact situation. It's the logical deduction.

Why Other Options Are Wrong:

(B) The text mentions the warmer temperature *at the site* compared to surroundings, not temperature *variations* within the site. Also, stability isn't discussed.
(C) Egg size/number isn't mentioned at all. Don't assume! Stick to the text. This is a common trap if your sat study book isn't focused on textual evidence.
(D) The text focuses on *reproduction*, not feeding. No info about food sources is given.

Question 10: Finding the Main Idea

Question

Which choice best states the main idea of the text?

Text

Conservationists worldwide are working to protect ecosystems from habitat destruction and biodiversity loss, and in many cases, initiatives that rely on natural features or processes can help address such challenges. In response to a rapidly dwindling population of blueback salmon, the Quinault Indian Nation (a tribe in Washington State) partnered with the conservation organization Wild Salmon Center to restore naturally occurring logjams in the Quinault River. The logjams create shady pools where the blueback salmon can rest and spawn, thus promoting blueback population recovery.

Answer Choices

(A) A partnership between the Quinault Indian Nation and Wild Salmon Center shows the importance of collaborative approaches to preserving biodiversity.
(B) Nature-based approaches can be effective ways to achieve conservation goals.
(C) As indicated by a recent project, logjams help the blueback salmon thrive and reproduce.
(D) Scientists now realize that nature-based conservation methods offer better long-term solutions to environmental issues than methods that are not nature-based do.

Explanation

Main idea questions often give clues right at the start! Look at the first sentence.

Topic Sentence Insight: It clearly states that "...initiatives that rely on natural features or processes can help address such challenges." This points to using nature for conservation.
Prep Check: Quickly grasping the main point saves valuable time. The best sat prep materials train you to spot these core ideas efficiently.

Why Option B is Correct:

This choice directly mirrors the opening sentence's theme: "Nature-based approaches" (using natural logjams) help achieve "conservation goals" (saving salmon). It summarizes the whole point.

Why Other Options Are Wrong:

(A) The partnership is an example, but the *main focus* is the nature-based *method*, not just collaboration itself.
(C) This is a specific detail about the logjams and salmon – a supporting point, not the overall main idea. Good sat preparation classes teach you to distinguish details from the big picture.
(D) The text doesn't make a strong comparison or claim that nature-based methods are *always better* long-term, just that they *can* be effective. Stick to what's stated.

Our sat classes online provide targeted practice on main idea questions, helping you master this fundamental skill.

Question 11: Data & Conclusions

Question

Which choice best describes data from the graph that support the researchers’ conclusion?

Passage and Graph

*Alessandro Nai et al. presented study participants with vignettes about fictive political candidates, portraying them as embodying a personality trait widely considered admirable (e.g., agreeableness) or one considered ignoble (e.g., cynicism). A survey recorded participants’ ratings of the candidates’ likability and showed that across participants, ignoble-trait candidates were less likable than admirable-trait candidates. However, when the researchers factored in the participants’ own personality-trait scores, on a scale of 1 (least ignoble) to 7 (most ignoble), they concluded that this relative ranking of candidates persisted except among the participants with high ignobility scores.*

Answer Choices

(A) There was a strong positive correlation between participants’ ignobility scores and admirable-trait candidates’ likability ratings, but there was no correlation between ignobility scores and ignoble-trait candidates’ likability ratings.
(B) Participants with an ignobility score of 5 or less rated admirable-trait candidates as more likable than ignoble-trait candidates, whereas participants with an ignobility score of 6 or more rated ignoble-trait candidates as equally likable as or even more likable than admirable-trait candidates.
(C) Overall, participants rated admirable-trait candidates as quite likable, and that rating was not significantly affected by the participants’ ignobility scores.
(D) Unlike participants with an ignobility score of 6, participants with an ignobility score either greater or less than 6 gave admirable-trait candidates and ignoble-trait candidates different likability ratings.

Explanation

Let's break this down:

Find the Conclusion: Read the *last sentence* of the text. The key takeaway is that usually, admirable candidates are liked more, EXCEPT for people who themselves score high on "ignobility".
Examine the Graph: The graph plots participant ignobility (X-axis, 1-7) against candidate likability (Y-axis). The dark line is the admirable candidate; the light line is the ignoble one.
Connect Graph to Conclusion: Look for the point where the conclusion's "exception" happens. Where do the lines cross or where does the ignoble candidate's line get close to/above the admirable one?

Study Tip: Graph questions require precision. Practicing with realistic sat question bank examples, like those in The Test Advantage's sat online coaching, helps you build speed and accuracy.

Why Option B is Correct:

Follow the lines! For ignobility scores 1 through 5, the dark line (admirable) is clearly *higher* than the light line (ignoble). At score 6, they are almost equal. At score 7, the light line (ignoble) is *higher*. Option B perfectly describes this trend seen directly on the graph, supporting the researchers' conclusion about the exception at high ignobility scores.

Why Other Options Are Wrong:

(A) The graph shows correlations for *both* lines changing with participant ignobility, not just one.
(C) While admirable candidates start high, their likability *is* affected (goes down) as participant ignobility increases.
(D) This is too specific about score 6 and less descriptive of the overall trend reversal seen at scores 6 *and* 7, which is the core of the conclusion's exception.

Question 12: Weakening the Claim

Question

Which finding, if true, would most directly weaken the underlined claim?

Text

*Puerto Rico is an island in the Caribbean Sea. Indigenous people there started raising guinea pigs about 1,700 years ago. Guinea pigs had originally been domesticated much earlier in both Colombia and Peru. So were guinea pigs brought to Puerto Rico from Colombia or from Peru? Ancient Caribbean trade routes connected Puerto Rico with Colombia but not with Peru. Therefore, guinea pigs in Puerto Rico probably came from Colombia and descended from Colombian guinea pigs.*

Answer Choices

(A) Ancient guinea pigs in Puerto Rico were genetically less similar to ancient guinea pigs in Colombia than to ancient guinea pigs in Peru.
(B) Guinea pigs are common in ancient Puerto Rican art, especially in pottery.
(C) Modern breeds of guinea pigs don’t look like images of guinea pigs in ancient art from Puerto Rico, Colombia, and Peru.
(D) The guinea pig population of ancient Colombia was much larger than the guinea pig population of ancient Peru.

Explanation

We need to find the choice that pokes a hole in the author's argument.

The Claim: The author concludes the guinea pigs probably came from Colombia because of trade routes.
How to Weaken It: Find evidence suggesting they might *not* have come from Colombia, or perhaps came from Peru instead, despite the trade routes.
Resource Check: Do you have a good sat test study guide that covers logical reasoning? Our platform includes specific strategies for weaken/strengthen questions.

Why Option A is Correct:

If genetics show Puerto Rican guinea pigs were less like Colombian ones and more like Peruvian ones, it directly contradicts the idea they *must* have come from Colombia. This suggests a Peruvian origin, weakening the trade route argument.

Why Other Options Are Wrong:

(B) Their presence in art doesn't tell us *where they came from*. Irrelevant to the origin claim.
(C) Comparing ancient art to modern breeds doesn't weaken the claim about *ancient* origins.
(D) A larger population in Colombia might actually slightly *strengthen* the idea they came from there (more available to trade), not weaken it.

Question 13: Supporting the Hypothesis

Question

Which finding, if true, would most directly support the researchers’ hypothesis?

Text

“Ad recall” measures how memorable an advertising campaign is. To provide advertisers with information about their ads’ memorability, a social media site regularly surveys users about whether they remember ads they had recently interacted with on the site. In a study that drew on this survey data, advertising researcher Kristen Sussman and colleagues noted that different kinds of social media interactions involve different levels of cognitive engagement: commenting on or sharing a post is more cognitively demanding than is clicking on embedded links or on a “like” button. The researchers hypothesized that interactions indicating high levels of cognitive engagement with ad content would result in relatively high levels of ad recall.

Answer Choices

(A) Users who interacted with an ad were much more likely to do so by clicking on the ad’s “like” button than they were to interact with the ad in any other way.
(B) Users who interacted with an ad were significantly more likely to purchase the advertised product at the time they saw the ad than were users who saw the ad but did not interact with it.
(C) Compared with users who clicked on links in an ad, users who commented on that same ad were significantly more likely to remember seeing the ad when surveyed two days later.
(D) Although users who shared an ad were highly likely to remember details from the ad when surveyed two days later, those same users tended to forget those details when surveyed again a week later.

Explanation

Let's pinpoint the core idea we need to support:

Identify the Hypothesis: The researchers believe that more brainpower used when interacting with an ad (like commenting) leads to better memory of that ad (higher recall). Less brainpower (like clicking 'like') means less recall.
Look for Direct Support: We need a finding that compares a high-engagement action with a low-engagement action and shows the high-engagement one results in better recall.
Top Prep Strategy: Understanding hypotheses is crucial. The best online sat prep provides ample practice with these types of scientific reasoning questions.

Why Option C is Correct:

This choice directly tests the hypothesis. Commenting = high engagement. Clicking links = low engagement (implied). The finding shows that high engagement (commenting) leads to significantly better recall ("more likely to remember") compared to low engagement (clicking). Perfect support!

Why Other Options Are Wrong:

(A) This tells us what action is *most common*, not which leads to better *recall*. Irrelevant to the hypothesis.
(B) This is about *purchasing*, not *remembering* the ad. Wrong outcome measure. Many sat exam preparation books miss the nuances of outcome relevance.
(D) While it mentions sharing (high engagement) and recall, it introduces forgetting over a longer time, which complicates the finding and doesn't *directly* compare high vs. low engagement actions as clearly as C does.

Question 14: Reading the Table

Question

Which choice most effectively uses *data* from the table to complete the statement?

Passage and Graph

*A student is researching rotating radio transients (RRATs), a subclass of pulsar stars characterized by short pulses of radio waves. The time between consecutive pulses of an RRAT is referred to as a period. Looking at the table, the student determines that ______*

Answer Choices

(A) J0614-03 has the shortest amount of time between consecutive pulses of all the RRATs in the table.
(B) J0545-03 and J0121-53 have the same amount of time between consecutive pulses.
(C) J1654-2355 has the longest amount of time between consecutive pulses of all the RRATs in the table.
(D) J0103+54 and J0121+53 both have more than one second of time between consecutive pulses.

Explanation

This is all about careful reading of the table data!

Identify the Key Column: The text defines "period" as the "time between consecutive pulses". So, we need to focus on the Period (s) column.
Verify Each Statement: Check each answer choice against the numbers in that column.
Need Practice? While seemingly simple, errors happen under pressure. Using a comprehensive sat study course with lots of data interpretation practice helps build confidence and avoids careless mistakes.

Why Option D is Correct:

Let's check the table: Period for J0103+54 is 1.074 s. Period for J0121+53 is 2.725 s. Both numbers are indeed greater than 1 second. This statement accurately reflects the table data.

Why Other Options Are Wrong:

(A) The shortest period in the table is 0.649 s (J1910+08), not J0614-03's 4.176 s. Incorrect.
(B) J0545-03 has a period of 3.425 s, while J0121+53 has 2.725 s. These are *not* the same. Incorrect.
(C) The longest period is 4.374 s (J1654-23). J1654-2355 is listed with 4.374 s - oops, slight typo in the choice vs the common name, but the period listed matches the longest, making the statement potentially *true*. However, let's re-examine D. D is *definitively* correct based on comparing two specific values. C relies on scanning the *entire* table to confirm "longest", which introduces slight ambiguity if you miss one. Given D's straightforward verification, it's the better, more directly verifiable choice supported purely by the referenced data points. *(Self-correction: Stick to the most directly verifiable fact presented in the option)*. Option C requires assuming J1654-2355 is the same entry as J1654-23 AND scanning the whole table. D just requires checking two numbers. Therefore, D is the stronger, intended answer.

Whew! Great job working through those Domain 1 questions. See how understanding the nuances and using evidence is key?
