- Which quotation from the novel most effectively illustrates Nand's claim?
Answer: "Felix, in instructing Safie, repeated the same words so often, that I was able to discover their meaning."
Nand argues that the Creature's language acquisition is portrayed as primarily shaped by eavesdropping, emphasizing passive observation over direct instruction. To illustrate this claim, we need a quotation showing the Creature learning language through observing others without being directly taught. Choice D perfectly illustrates this: "Felix, in instructing Safie, repeated the same words so often, that I was able to discover their meaning" shows the Creature learning by overhearing Felix teach someone else, exemplifying passive observation and eavesdropping. Choice A addresses self-perception, not language learning. Choice B describes recognizing that language exists but not the acquisition method. Choice C mentions the Creature improving in language but suggests active participation ("she and I"), which contradicts the passive observation claim. In literary evidence questions, ensure the quotation directly addresses the specific aspect of the claim—here, the method of language acquisition through eavesdropping.
- Which finding, if true, would most directly support Chen's hypothesis?
Answer: At 70 dB, participants show higher creativity scores and modestly slower response times than in silence.
Chen hypothesizes that moderate café noise (around 70 dB) improves creative problem solving because it slightly increases cognitive load, encouraging more abstract processing. To support this, we'd need evidence showing that 70 dB noise both increases creativity and creates the proposed mechanism (slight cognitive load increase). Choice B directly supports this hypothesis: participants show higher creativity scores at 70 dB (supporting the improved problem solving claim) and modestly slower response times (indicating the slight increase in cognitive load that Chen proposes as the mechanism). Choice C shows negative effects at higher noise levels, which doesn't test the specific 70 dB claim. Choice A addresses persistence rather than creativity. Choice D shows correlation in natural settings but doesn't test the causal mechanism. When evaluating experimental support for mechanistic hypotheses, look for evidence of both the outcome (improved creativity) and the proposed mechanism (increased cognitive load).
- Which observation would best support Okafor's argument?
Answer: Soils inside the circles show higher phosphate levels, compacted layers, and abundant herbivore dung spherulites relative to nearby control samples.
Archaeologist Leila Okafor proposes that stone circles on a Sahelian plateau served as seasonal livestock corrals from 900 to 1100 CE, based on expected microstratigraphic signatures like compacted soils and elevated phosphates from dung inside the circles compared to surroundings. To support this argument, an observation would need to reveal these distinctive soil markers inside the circles, differentiating them from ritual uses lacking animal evidence. Choice A best supports Okafor's argument by noting higher phosphates, compaction, and dung spherulites inside versus control samples, directly matching the predicted signatures of repeated animal penning. This provides probative evidence for functional rather than symbolic use in the proposed period. Choice B involves a distant artifact from a different era, lacking site connection, while Choice C addresses regional drought post-dating the period. Choice D dates external charcoal later, not addressing internal soil evidence. In archaeological claims, prioritize site-specific physical evidence like soil chemistry that tests functional hypotheses over indirect or temporally mismatched findings.
- Which finding, if true, would most directly support Iversen's argument?
Answer: Working-memory scores improve only when measured within an hour of exercise and correlate with post-exercise blood-flow increases.
Neuroscientist Dana Iversen argues that short aerobic exercise bouts improve adult working-memory performance mainly via increased cerebral blood flow in the immediate post-exercise hour, not through long-term brain structure changes. To support this, we'd need evidence tying memory gains to short-term blood flow without structural alterations. Choice B directly reinforces this by showing improvements only within an hour of exercise, correlating with blood-flow increases, emphasizing the temporary mechanism over enduring changes. Choice A describes hippocampal volume growth after months of training, which points to long-term structural effects rather than acute benefits. Choice C links mood to concentration anecdotally, not to memory or blood flow, while Choice D compares athletes to sedentary adults without isolating short-term exercise effects. For claims about temporal mechanisms, prioritize findings that align benefits with the proposed timeframe, like immediate post-exercise here, while excluding longer-term alternatives.
- Which sentence in the passage supplies the clearest evidence for long-distance transport of cacao by ancient peoples?
Answer: "Archaeologist Daniel Kim excavated a coastal settlement where he discovered pottery shards bearing traces of cacao residue."
This question tests your ability to identify textual evidence that directly supports a claim about ancient trade practices. When looking for evidence in reading passages, you need to distinguish between statements that directly demonstrate something versus those that merely suggest, analyze, or provide background context.
Choice D provides the clearest evidence because it presents the concrete archaeological discovery: pottery shards with cacao residue found at a coastal settlement. This physical evidence directly demonstrates that cacao was present in a location where it wouldn't naturally grow, which inherently proves long-distance transport occurred. The evidence speaks for itself without requiring interpretation.
Choice A is incorrect because it describes the scientific method used to analyze the pottery, not the evidence of transport itself. While mass spectrometry confirms what was found, it doesn't establish the significance of the location or distance traveled.
Choice B is wrong because it presents the archaeologist's interpretation or conclusion about the evidence rather than the evidence itself. The phrase "suggests that" indicates this is an inference drawn from the data, not the direct evidence.
Choice C is incorrect because local legends constitute oral tradition rather than concrete archaeological evidence. Legends may support the findings but aren't reliable historical evidence on their own.
Remember: when questions ask for "evidence" or "support," look for concrete facts, data, or observations rather than conclusions, interpretations, or background information. The strongest evidence usually consists of specific, measurable findings that directly relate to the claim being made.
- Which passage detail best supports the conclusion that the beetles' infrared glow functions as a defensive signal?
Answer: Predators retreated each time the glow appeared during Li's thermal camera observations.
When you encounter questions asking which detail "best supports" a conclusion, you're looking for direct evidence that proves the claim, not just related information.
The conclusion states that the infrared glow functions as a "defensive signal." To support this, you need evidence showing the glow actually defends the beetles from threats. Choice B provides exactly this proof: "Predators retreated each time the glow appeared during Li's thermal camera observations." This demonstrates a clear cause-and-effect relationship where the glow directly causes predators to back away, proving its defensive function.
Let's examine why the other choices fall short. Choice A tells us the beetles glow "when threatened," which shows the timing of the behavior but doesn't prove it actually works as defense—the glow could be coincidental or ineffective. Choice C describes the beetles' habitat conditions, explaining why they might use infrared instead of visible signals, but this context doesn't prove the signal successfully deters predators. Choice D simply states where the research was published, which has no bearing on whether the glow functions defensively.
The key distinction is between describing what happens versus proving it works. Only choice B shows the glow achieving its supposed purpose by actually making predators retreat.
Remember: when questions ask for supporting evidence, look for the choice that directly demonstrates the claimed outcome, not just circumstances surrounding it. Evidence must show results, not just describe conditions or timing.
- Which observation would best support Okoye's argument?
Answer: After catch shares begin, reported rule violations fall most in villages with the highest rates of inter-household visits.
Okoye contends that catch shares reduce overfishing mainly through increased peer monitoring (fishers observing and sanctioning each other), not through market price changes. To support this, we'd need evidence showing that peer monitoring mechanisms are active and effective after catch shares begin. Choice B directly supports this by showing that rule violations fall most in villages with the highest rates of inter-household visits—this suggests that communities with more social interaction (enabling peer monitoring) see the greatest compliance improvements. Choice A mentions price changes, which Okoye explicitly argues are not the main mechanism. Choice D addresses vessel size differences but doesn't connect to peer monitoring. Choice C is about a different region without catch shares, making it irrelevant to testing Okoye's claim. When evaluating support for social mechanism claims, look for evidence that the proposed social process (peer monitoring) correlates with the desired outcome (reduced violations).
- Which finding, if true, would most directly support Weber's claim?
Answer: Counties with larger manufacturing declines show higher overdose deaths only where long‑term unemployment rises, not where workers quickly reemploy.
The economist claims that manufacturing declines increased overdose deaths mainly through long-term unemployment (sustained income/structure loss), not short-term job transitions. To support this, we'd need evidence showing overdoses increase specifically where long-term unemployment rises, not where workers quickly find new jobs. Choice A directly supports this by showing counties with manufacturing declines have higher overdoses only where long-term unemployment rises, not where workers quickly reemploy—this isolates the long-term unemployment mechanism. Choice B shows overdoses in counties without manufacturing decline, which doesn't test the claim about manufacturing's effect. Choice C addresses prescription practices, not the unemployment mechanism. Choice D shows education responses to layoffs, not health outcomes. When evaluating mechanism claims, look for evidence that compares outcomes when the proposed mechanism is present versus absent.
- Which portion of the passage provides the best evidence that the tomato plants responded specifically to the audio stimulus?
Answer: "Within hours, the plants produced elevated levels of defensive chemicals, even though no insects were present on their leaves."
This question tests your ability to identify textual evidence that directly supports a specific claim. When you see "best evidence" questions, look for the answer choice that most directly proves the point being asked about.
The question asks which portion shows that tomato plants responded "specifically to the audio stimulus." This means you need evidence that rules out other possible causes for the plants' defensive response and confirms it was the sound recordings that triggered the reaction.
Choice B provides this evidence perfectly: "Within hours, the plants produced elevated levels of defensive chemicals, even though no insects were present on their leaves." The phrase "even though no insects were present" is crucial—it eliminates the most obvious alternative explanation for why plants would produce defensive chemicals. Since there were no actual insects physically attacking the plants, the defensive response must have been triggered by the audio recordings alone.
Choice A only describes the experimental setup (exposing plants to recordings) but doesn't show that the plants actually responded. Choice C gives irrelevant details about laboratory conditions that don't address whether plants responded to sound. Choice D mentions previous studies with real insect attacks, which actually suggests an alternative cause rather than proving the audio stimulus was responsible.
The key strategy for evidence questions is to look for text that directly eliminates alternative explanations or provides concrete proof of the claim. Watch for qualifying phrases like "even though," "despite," or "although"—these often signal important evidence by ruling out competing factors.
- Which sentence provides the primary evidence for Patel's claim regarding the urban 'albedo boost' effect on solar panels?
Answer: "In dense cities, this 'albedo boost' can increase total energy output by up to 12 percent."
When you encounter a question asking for "primary evidence" for a claim, you need to distinguish between statements that make a claim and statements that provide concrete support for that claim.
Patel's claim is that solar panels can benefit from an "albedo boost" effect in urban environments. The correct answer is B because it provides quantifiable evidence: "In dense cities, this 'albedo boost' can increase total energy output by up to 12 percent." This sentence gives us measurable data (12 percent increase) that directly supports the claim about the albedo boost's effectiveness.
Let's examine why the other choices don't serve as primary evidence. Choice A introduces Patel's observation about solar panels harvesting diffuse light, but this is more of a general statement about the phenomenon rather than evidence proving its significance. Choice C discusses what architects are doing with reflective materials, but this describes applications rather than providing evidence for the albedo boost's effectiveness. Choice D explains the etymology of "albedo," which is background information that doesn't support the claim about energy output increases.
The key distinction here is between explanation and evidence. Choices A, C, and D explain concepts, describe related activities, or provide background, while only choice B offers concrete, measurable proof of the albedo boost's impact.
When tackling evidence questions on the PSAT, look for statements containing specific data, statistics, or measurable outcomes rather than general descriptions or background information. Evidence answers typically include numbers, percentages, or quantifiable results that directly support the claim in question.
- Which finding, if true, would most directly support Patel's hypothesis?
Answer: When teams shifted from scattered to clustered meetings without changing total meeting time, code output and review speed increased most for complex projects.
Psychologist Amina Patel argues that in fully remote teams of knowledge workers in software and data roles, meeting overload reduces productivity primarily through task-switching costs from frequent, scattered meetings that fragment attention on complex tasks. To support this hypothesis, evidence would need to show improved productivity when meetings are clustered rather than scattered, without changes in total meeting time, especially for complex work. Choice C directly supports Patel's claim by demonstrating that shifting to clustered meetings increased code output and review speed, particularly for complex projects, while keeping total time constant, thus isolating the effect of reduced task-switching. This matches the hypothesis's focus on scattering as the key issue in remote settings. Choice A addresses total meeting hours and satisfaction but not the scattering versus clustering distinction, while Choice B discusses meeting formats like video calls, which are unrelated to timing. Choice D involves equipment like monitors, not meeting structure. In studies of workplace dynamics, evidence for causal claims about productivity requires controlling for confounders like total time to pinpoint mechanisms like task-switching.
- Which discovery would most strongly undermine Armand's theory?
Answer: Company leisure clubs expanded most rapidly after 1920, while fraternal lodge membership had already stabilized by 1910.
Armand's theory claims that employer-sponsored leisure clubs drove declining lodge membership between 1890-1910 by offering similar benefits with lower costs. To undermine this theory, we'd need evidence showing either that the timing doesn't match (clubs didn't expand when lodges declined) or that a different factor caused the decline. Choice A directly undermines the theory by showing that company leisure clubs expanded most rapidly after 1920, which is after the 1890-1910 period when lodge membership supposedly declined due to these clubs—if the clubs weren't prevalent during the decline, they couldn't have caused it. Choice C actually supports a competing explanation (rising fees) but doesn't directly contradict Armand's theory since both factors could contribute. Choice D shows coexistence of both memberships, which doesn't necessarily undermine the claim about declining lodge membership. In historical causation questions, pay close attention to chronology—causes must precede their supposed effects.
- Which finding, if true, would most directly support Patel's hypothesis?
Answer: Students using spaced recall quizzes remember more words after two weeks than peers with equal study time but massed review.
The psychologist claims that for ages 6-8, second language vocabulary learning improves specifically through spaced retrieval practice (repeated recall over days), not just more exposure time. To support this, we'd need evidence showing spaced retrieval outperforms equal-time massed practice for retention. Choice B directly supports this by showing students using spaced recall quizzes remember more words after two weeks than peers with equal study time but massed review—this isolates the spacing effect from total time. Choice A addresses total exposure through longer stories, not the spacing of practice. Choice C contradicts the claim by showing no difference, though for older students (14-16) not the target age group. Choice D addresses engagement, not learning outcomes. When evaluating educational interventions, pay attention to whether studies control for total time and measure the specific outcome of interest.
- Which finding, if true, would most directly undermine Iqbal's claim?
Answer: Exit polls show 18–24-year-olds prefer major parties at the same rate as older voters in high-turnout elections.
Iqbal claims that in proportional-representation elections, higher youth turnout increases small party vote share because young voters prefer niche platforms. To undermine this claim, we'd need evidence showing that young voters don't actually prefer small parties more than older voters when they turn out. Choice B directly undermines the claim by showing that 18-24-year-olds prefer major parties at the same rate as older voters in high-turnout elections—this contradicts the core assumption that young voters are more willing to support niche platforms. Choice A shows stable party shares but doesn't specifically address youth preferences. Choice C identifies a different factor affecting small parties. Choice D actually supports a version of Iqbal's claim but in a different electoral system. When evaluating claims about demographic voting patterns, direct evidence about that demographic's actual preferences most effectively confirms or undermines the argument.
- Which finding, if true, would most directly support Liu's hypothesis?
Answer: Across parks, native plantings maintain continuous bloom coverage for 18 weeks, and bee species richness tracks that coverage weekly.
Liu's hypothesis claims that native plants increase bee diversity specifically because they provide a longer, season-spanning sequence of blooms compared to nonnative plantings. To support this, we'd need evidence showing that native plants maintain continuous blooms across seasons AND that bee diversity directly tracks this extended bloom coverage. Choice B provides exactly this evidence: it shows native plantings maintain bloom coverage for 18 weeks (demonstrating the extended season-spanning sequence) and that bee species richness tracks this coverage weekly (demonstrating the causal link between extended blooms and bee diversity). Choice A contradicts the hypothesis by showing benefits only in spring rather than across seasons. Choice D addresses a different setting (rural meadows) and crucially doesn't measure bloom timing, which is central to Liu's mechanism. When evaluating evidence for causal claims, ensure the evidence tests both the proposed mechanism (extended bloom sequence) and its effect (increased bee diversity).
- Which observation would best support Nandakumar's argument?
Answer: Teams with stable reply latency show rising trust scores, even when total message counts remain low and unchanged.
The sociologist argues that remote team trust develops mainly through predictable response timing (reliable reply windows) rather than increased message volume. To support this, we'd need evidence showing trust increases with consistent timing even without high message volume. Choice B directly supports this by showing teams with stable reply latency have rising trust scores even when message counts remain low and unchanged—this isolates the timing predictability effect from volume. Choice A contradicts by showing trust correlates with message volume despite variable timing. Choice C compares in-person to remote teams, not testing the mechanism within remote teams. Choice D addresses platform preferences, not trust development. When evaluating competing explanations, look for evidence that holds one factor constant while varying the other.
- Which sentence best supports Saeed's argument that economic factors led to the city's downfall?
Answer: "He cites merchant records showing a 70 percent drop in grain imports during the decade preceding the siege."
When you encounter questions asking which sentence "best supports" an argument, you're being tested on your ability to distinguish between claims and evidence. You need to identify concrete proof rather than just restatements of the position.
Choice B provides the strongest support for Saeed's economic crisis argument because it presents specific, quantifiable evidence: merchant records documenting a 70% drop in grain imports during the decade before the siege. This data directly demonstrates economic decline and supports the theory that internal economic problems, rather than external military force, caused the city's vulnerability. The timing is crucial—this economic decline happened before the siege, suggesting it was a contributing cause rather than a consequence.
Choice A is incorrect because it simply restates Saeed's argument without providing any supporting evidence. It's the claim itself, not proof of the claim. Choice C contradicts Saeed's argument by emphasizing the city's military strength, which would actually support the idea that military factors weren't the primary cause of the fall. Choice D focuses on the aftermath of conquest and the conqueror's actions, but doesn't address the underlying causes that made the city vulnerable in the first place.
Remember this pattern: when questions ask what "supports" an argument, look for concrete evidence like statistics, data, examples, or documented facts rather than opinions or restatements of the claim. The best support will directly connect to the specific argument being made and provide measurable proof of the position.
- Which statement from the passage most directly evidences the connection between the bike-share launch and reduced car congestion?
Answer: "Car congestion during rush hour dropped by an average of eight minutes per mile, coinciding with a 25 percent uptick in bike usage on major corridors."
When you encounter questions asking for evidence of a connection or relationship, you need to identify which statement directly shows both elements working together, not just mentions them separately.
Choice B is correct because it provides the strongest evidence linking the bike-share system to reduced car congestion. The phrase "coinciding with" explicitly connects the timing of decreased car congestion (eight minutes per mile reduction) with increased bike usage (25% uptick). This temporal correlation directly supports the claim that the bike-share launch influenced traffic patterns.
Choice A is wrong because it only establishes that a study was conducted—it doesn't provide any actual evidence or results about the connection between bike-sharing and congestion. Choice C is incorrect because while it mentions a program feature (free first half-hour), it doesn't address traffic congestion at all, so it can't evidence a connection to reduced car traffic. Choice D is wrong because it describes promotional activities but provides no data about their impact on either bike usage or car congestion.
The key distinction is between statements that simply mention relevant topics versus statements that demonstrate a relationship. Only choice B shows measurable changes in both variables (car congestion and bike usage) occurring simultaneously.
Strategy tip: For evidence-based questions, look for statements that contain concrete data or explicit linking words like "coinciding with," "resulting in," or "caused by." Avoid choices that only describe background information or single variables without showing connections.
- Which finding, if true, would most directly support Salas's interpretation?
Answer: Storerooms contain many small, standardized sealings and few large bins, consistent with frequent packing and redistribution.
Salas argues the settlement was a seasonal trade outpost rather than year-round village because storage facilities were designed for short-term, high-volume goods turnover. To support this interpretation, we'd need evidence showing storage patterns consistent with frequent movement of trade goods rather than long-term residential storage. Choice D provides exactly this evidence: many small, standardized sealings (suggesting frequent packaging of goods) and few large bins (inconsistent with long-term bulk storage) directly support the interpretation of short-term, high-volume turnover typical of trade outposts. Choice B actually contradicts Salas by showing long-term maintenance suggesting year-round occupation. Choice A addresses fuel sources, not storage patterns. Choice C mentions imported vessels but doesn't analyze storage facilities or turnover patterns. In archaeological interpretation questions, ensure the evidence directly addresses the specific material pattern (storage design) that forms the basis of the argument.
- Which finding, if true, would most directly challenge Alvarez's claim?
Answer: Customs ledgers show trade tonnage doubled from 1610 to 1630 while naval payrolls stayed stable and desertion rates fell.
The historian claims that the 1610-1630 piracy rise was driven mainly by demobilized sailors after a conflict ended, not by increased trade volume. To challenge this, we'd need evidence showing either that demobilized sailors weren't the main cause or that increased trade was the main cause. Choice A directly challenges the claim by showing trade doubled while naval forces stayed stable with low desertion—this suggests increased trade targets drove piracy, not an influx of unemployed sailors. Choice B mentions new hideouts but doesn't address the cause of increased piracy. Choice C discusses moral explanations from 1650, outside the relevant timeframe. Choice D shows unchanged piracy in a different region (eastern Mediterranean), not the western Mediterranean in question. To challenge a causal claim about what drove an increase, look for evidence supporting an alternative cause or contradicting the proposed cause.
