Question 1Hard
Ecologist Judy Stamps has proposed that natal habitat preference induction (NHPI) may explain why some invasive species establish themselves rapidly while others fail. NHPI occurs when young animals develop a preference for habitat characteristics they experience early in life, later seeking similar environments for breeding. Stamps observed that European starlings introduced to North America in the 1890s initially nested in urban areas resembling their native European cities, but their offspring, having imprinted on American urban features, successfully colonized a broader range of habitats including agricultural areas. In contrast, crested mynas introduced to Vancouver in the same period remained restricted to urban cores for decades, and their population eventually declined. Given that both species are habitat generalists in their native ranges, Stamps concluded that _____
Which choice most logically completes the text?
Show the answer and explanation
Why A is right
The contrasting outcomes for starlings and mynas, despite both being habitat generalists, supports the conclusion that intergenerational habitat preference development affects invasion success. Starlings whose offspring imprinted on diverse habitats spread widely, while mynas whose offspring did not remained restricted, suggesting NHPI influences invasion outcomes through this mechanism.
Why the others are wrong
BThis restates the evidence about starling colonization patterns rather than inferring the general principle about invasive species success that Stamps derived from comparing the two cases.
CThis overgeneralizes by stating NHPI determines every invasion outcome when Stamps proposes it as one explanatory factor that may help explain differential success rates.
DThis addresses native-range adaptability, but the passage establishes both species are habitat generalists in native ranges, so the comparison concerns offspring imprinting in new environments, not native adaptability.
Question 2Hard
In a 2023 study, cognitive psychologist Elena Vargas examined how bilingual individuals process numerical information. Participants were presented with arithmetic problems in both their native language and their second language. Vargas found that response times were statistically indistinguishable between the two languages when problems involved addition or subtraction, but participants consistently solved multiplication problems faster in whichever language they had originally learned multiplication tables.
Based on the text, which statement must be true?
Show the answer and explanation
Why B is right
The passage explicitly states that participants solved multiplication problems faster in the language they originally learned multiplication tables in, directly supporting that the learning language affects solving speed.
Why the others are wrong
AThe passage discusses response times, not accuracy, and provides no information about native versus second language performance in terms of correctness.
CWhile response times for addition and subtraction were similar across languages, the passage does not compare the cognitive demands of different operations.
DThe passage describes participants as bilingual but does not specify they spoke exactly two languages rather than more than two.
Question 3Hard
Historian Sven Beckert has examined how nineteenth-century cotton production linked the American South, British factories, and Indian markets in a single economic system. Beckert shows that British manufacturers depended on cheap cotton from Southern plantations worked by enslaved laborers, while the textiles these factories produced were sold in colonial India, displacing local handloom weavers. When the American Civil War disrupted cotton supplies in the 1860s, British merchants rapidly expanded cotton cultivation in Egypt and India using coercive labor systems. This pivot occurred within months, suggesting that the entire network was structured to maintain production regardless of local political upheavals. Beckert's research therefore indicates that _____
Which choice most logically completes the text?
Show the answer and explanation
Why B is right
The evidence shows that when one source of coerced labor was disrupted, the system rapidly shifted to alternative sites also using coerced labor, and that the network was structured to maintain production despite upheavals. This pattern supports the inference that the capitalist cotton economy was systematically organized around exploiting forced labor wherever it could be accessed.
Why the others are wrong
AThis restates the evidence about trade connections that was established early in the passage rather than drawing a conclusion about the structural logic of the economic system.
CThis overgeneralizes by extending the claim to all economic systems throughout history when Beckert's research addresses specifically nineteenth-century capitalism.
DThis addresses the relative power of different actors within the system, but the passage's evidence points toward conclusions about the system's structural reliance on coerced labor, not about power hierarchies among capitalists.
Question 4Hard
Historian Michael Chen's analysis of colonial trade records from 1780 to 1820 reveals that while European merchants frequently documented the quantities and prices of goods exchanged, they rarely recorded the names or origins of the indigenous intermediaries who facilitated these transactions. Chen argues that this pattern of omission was not accidental but reflected a deliberate effort to minimize the documented role of indigenous agents in the colonial economy, thereby supporting narratives of European economic primacy.
Based on the text, which statement must be true?
Show the answer and explanation
Why B is right
The passage directly states that merchants frequently documented goods but rarely recorded information about indigenous intermediaries, establishing that records contain more information about goods.
Why the others are wrong
AThe passage indicates the information was rarely recorded, not that merchants were unable to obtain it.
CChen offers an interpretation, but the passage does not claim this is the only possible explanation for the pattern.
DWhile Chen's argument implies this, the passage does not provide evidence that directly establishes the significance of their role as a fact.
Question 5Hard
In studying the evolution of venom resistance in certain snake predators, biologist Lynne Hobday found that California ground squirrels possess a serum protein that neutralizes the toxins in rattlesnake venom. Hobday then examined populations of these squirrels living in regions with and without rattlesnakes. She discovered that squirrels from rattlesnake-inhabited areas exhibited significantly higher concentrations of the protective protein than squirrels from rattlesnake-free zones, even when both groups were raised under identical laboratory conditions. This pattern held across multiple generations, suggesting that _____
Which choice most logically completes the text?
Show the answer and explanation
Why A is right
The passage establishes that squirrels from rattlesnake-inhabited areas have higher concentrations of the protective protein even when raised in identical laboratory conditions across multiple generations. This persistence across generations in controlled environments indicates a heritable, genetically based difference shaped by evolutionary selection pressure from rattlesnake predation.
Why the others are wrong
BThis choice merely restates evidence already given in the passage (that squirrels possess the protein) rather than drawing the logical inference about differential selection pressure.
CThis overgeneralizes the specific finding about California ground squirrels and rattlesnakes to all ground squirrel species and all venomous snakes, a claim not supported by the evidence.
DThis addresses the evolution of rattlesnake venom rather than the evolution of squirrel resistance, swapping the question from prey adaptation to predator adaptation.
Question 6Hard
Ecologist David Matsumoto tracked the foraging behavior of black-capped chickadees across different forest environments over a two-year period. Matsumoto observed that in areas where food sources were distributed unpredictably, chickadees cached significantly more food items per day than in areas where food was reliably abundant. However, retrieval rates were similar across both environments. Matsumoto proposes that chickadees in unpredictable environments may be caching additional food as a precautionary measure, even though they retrieve food at the same rate.
Based on the text, which statement must be true?
Show the answer and explanation
Why B is right
The passage explicitly states that chickadees cached significantly more food per day in unpredictable environments than in reliably abundant ones, establishing that caching rate varies with food predictability.
Why the others are wrong
AThe passage discusses caching and retrieval rates but provides no information about actual consumption.
CMatsumoto proposes an explanation but the passage does not indicate this has been definitively proven.
DWhile likely true, this describes the study setup rather than a necessary inference from the findings about behavior.
Question 7Hard
Botanist Elena Vasquez investigated the relationship between mycorrhizal fungal networks and drought resistance in prairie ecosystems. In controlled experiments, Vasquez established plots where plant roots could access established fungal networks and comparable plots where fungal networks were chemically suppressed. During a simulated eight-week drought, plants with fungal network access maintained 73 percent of their pre-drought photosynthetic capacity, while isolated plants retained only 41 percent. Vasquez then analyzed carbon isotope ratios in plant tissues and discovered that networked plants showed evidence of receiving water redistributed from deeper-rooted neighboring species through the fungal connections. This finding implies that _____
Which choice most logically completes the text?
Show the answer and explanation
Why A is right
The passage establishes that networked plants maintained better photosynthetic capacity and received redistributed water from deeper-rooted neighbors through fungal connections. This evidence of resource transfer logically supports the inference that networks enable community-level resilience through resource sharing, going beyond individual adaptations.
Why the others are wrong
BThis restates the comparative performance data already presented (73 percent versus 41 percent photosynthetic capacity) without drawing the interpretive conclusion about resource-sharing mechanisms.
CThis overgeneralizes the specific finding about prairie plant communities during Vasquez's experiment to an absolute claim about all terrestrial plant communities and all water stress.
DThis addresses the water access capabilities of deeper-rooted species rather than the significance of fungal networks as resource-sharing conduits, swapping the question from network function to root architecture.
Question 8Hard
In the 1920s, the German architect Bruno Taut proposed that colors applied to building exteriors could transform urban environments by enhancing psychological well-being. Taut's color schemes for Berlin's housing estates employed vibrant hues—reds, blues, yellows—on facades that had traditionally been rendered in muted tones. Contemporary critics dismissed these interventions as frivolous, insisting that architectural merit resided in form and structure rather than surface decoration. However, recent studies by environmental psychologists have found that residents in Taut's color-enhanced estates reported significantly higher satisfaction with their neighborhoods than those in comparably designed but monochromatically painted developments, even when controlling for variables such as income and building age. This finding suggests that _____
Which choice most logically completes the text?
Show the answer and explanation
Why A is right
The passage establishes that Taut believed color could enhance well-being, that critics dismissed this idea, and that recent evidence shows residents in his color-enhanced estates had higher satisfaction. The logical inference is that Taut's color interventions may have produced the psychological benefits he proposed, contrary to his critics' views.
Why the others are wrong
BThis choice overgeneralizes by claiming surface treatments are invariably more influential than structure. The passage only supports that color contributed to satisfaction in these specific cases, not that surface is always more important than form.
CThis choice restates evidence already provided in the passage rather than drawing an inference from it. The passage explicitly states this finding; the blank requires a conclusion that follows from it.
DThis choice addresses a different question about whether the benefits extend to non-residential buildings. The passage only provides evidence about housing estates, so this conclusion about all building types is not supported.
Question 9Hard
Literary scholar Patricia Kimball has examined narrative voice in the fiction of Zora Neale Hurston, focusing on the relationship between dialogue and exposition. Kimball observes that in Hurston's novel Their Eyes Were Watching God, dialogue passages render characters' speech in rich vernacular dialect with nonstandard grammar and phonetic spellings, while expository passages describing characters' thoughts and the narrator's observations employ standard literary English with conventional syntax. Other Harlem Renaissance authors writing during the same period, Kimball notes, typically maintained consistent linguistic registers throughout their narratives, using either vernacular or standard English but rarely alternating between them within a single work. Kimball proposes that Hurston's technique _____
Which choice most logically completes the text?
Show the answer and explanation
Why A is right
The passage describes Hurston's systematic alternation between vernacular dialogue and standard expository prose, contrasting with contemporaries who maintained uniform registers. This deliberate switching logically supports Kimball's interpretive claim that Hurston created meaningful distinction between character voices and narrative perspective.
Why the others are wrong
BThis makes a comparative value judgment about Hurston's linguistic skill versus her peers rather than explaining the interpretive significance of her technique, swapping aesthetic analysis for qualitative ranking.
CThis restates the contrast between Hurston's alternating registers and her contemporaries' consistent registers already described in the passage without articulating Kimball's interpretation of Hurston's technique.
DThis overgeneralizes Hurston's individual technique into a universal standard for all subsequent African American novelists, an unsupported claim about literary influence.
Question 10Hard
Historian Amara Okonkwo has examined legal records from the Ottoman Empire during the seventeenth century, particularly cases involving commercial disputes in Mediterranean port cities. Okonkwo discovered that in cities with substantial European merchant populations, Ottoman judges frequently incorporated provisions from European commercial codes when adjudicating disputes between Ottoman and European traders, even when Ottoman law would have dictated different outcomes. However, in disputes exclusively between Ottoman subjects, judges applied traditional Ottoman commercial law without deviation. Okonkwo found no official legal directives authorizing judges to blend legal traditions in this manner. This pattern most strongly suggests that _____
Which choice most logically completes the text?
Show the answer and explanation
Why B is right
The passage shows that judges incorporated European legal provisions in cross-cultural cases despite no official authorization to do so, while maintaining traditional Ottoman law in purely Ottoman disputes. This selective adaptation, undertaken without formal directive, most logically reflects pragmatic judicial flexibility aimed at accommodating international commerce.
Why the others are wrong
AThis addresses European merchants' preferences rather than explaining why Ottoman judges chose to exercise flexibility, swapping the question from judicial motivation to merchant behavior.
CThis simply restates the pattern of judicial behavior already described in the passage without drawing an inference about the underlying motivation or significance of this pattern.
DThis extends the specific finding about Ottoman judges in certain port cities to a sweeping claim about all early modern judicial systems worldwide, an unsupported overgeneralization.
Question 11Hard
Astrophysicist Priyamvada Natarajan has proposed that supermassive black holes in the early universe may have formed through direct collapse of massive gas clouds rather than through gradual growth from stellar-mass black holes. Natarajan calculated that for stellar-mass black holes (formed from dying stars) to grow to the billion-solar-mass supermassive black holes observed in quasars just 800 million years after the Big Bang, they would need to accrete matter continuously at the maximum theoretical rate, a condition unlikely to persist for hundreds of millions of years. However, her models show that under specific conditions—gas clouds of at least 100,000 solar masses in metal-poor environments—gravitational collapse could produce black holes of 10,000 to 100,000 solar masses directly. Such "seed" black holes could reach supermassive scale within the observed timeframe through realistic accretion rates. This analysis suggests that _____
Which choice most logically completes the text?
Show the answer and explanation
Why A is right
Natarajan shows that gradual growth requires implausibly sustained maximum accretion, while direct collapse can produce seed black holes that reach supermassive scale through realistic accretion. This evidence supports the inference that direct collapse provides a more plausible explanation for early supermassive black holes than gradual growth.
Why the others are wrong
BThis restates the evidence about the implausible requirements for gradual growth rather than drawing the conclusion about which formation mechanism better explains observations.
CThis overgeneralizes by claiming all supermassive black holes formed through direct collapse when Natarajan's argument addresses specifically early-universe supermassive black holes where timing constraints are most severe.
DThis addresses whether quasar masses were miscalculated, but the passage concerns which formation mechanism can produce the observed masses in the observed timeframe, not whether the observations themselves are accurate.
Question 12Hard
Archaeologist Chen Wei has investigated fortification patterns in early Bronze Age settlements across the Yellow River valley in China. Chen documented that settlements positioned along major tributaries consistently featured defensive walls exceeding four meters in height with multiple gate systems, while settlements located more than five kilometers from navigable waterways typically had walls under two meters in height with single entry points. Analysis of artifacts recovered from these sites revealed that riverside settlements contained substantially higher proportions of non-local materials—including jade from distant sources and copper tools of foreign manufacture—compared to inland settlements. Chen concluded that _____
Which choice most logically completes the text?
Show the answer and explanation
Why D is right
The passage links riverside location with both more elaborate fortifications and greater presence of non-local trade goods. The logical inference connecting these patterns is that waterborne trade brought both wealth (evidenced by foreign materials) and threats (necessitating strong defenses), creating incentives for defensive investment.
Why the others are wrong
AThis extends the specific finding about Yellow River valley settlements to a sweeping claim about all Bronze Age East Asian settlements, an unsupported overgeneralization.
BThis addresses geographical suitability for fortification architecture rather than the relationship between trade participation and defensive investment, swapping the economic explanation for a topographical one.
CThis simply restates the correlation between riverside location, fortification elaboration, and non-local materials already described, without drawing Chen's interpretive conclusion linking trade and security.
Question 13Hard
Art historian Thomas Brennan has investigated the reception of Baroque painter Artemisia Gentileschi's work during her lifetime versus in contemporary scholarship. Brennan notes that seventeenth-century patrons and critics praised Gentileschi primarily for her technical skill in rendering fabrics and flesh tones, rarely commenting on her paintings' dramatic narratives or psychological intensity. In contrast, twentieth and twenty-first century scholars have focused extensively on Gentileschi's powerful depictions of female agency and her strategic reinterpretations of biblical and mythological scenes. Brennan found no evidence that Gentileschi's compositional choices or subject matter differed systematically from those of her male contemporaries who received less scholarly attention in modern times. These findings indicate that _____
Which choice most logically completes the text?
Show the answer and explanation
Why A is right
The passage establishes that seventeenth-century viewers praised technical skill while modern scholars emphasize themes of female agency and reinterpreted narratives. Since these themes exist in the paintings regardless of when they are viewed, the logical inference is that contemporary scholars perceive or emphasize elements that earlier viewers did not.
Why the others are wrong
BThis addresses Gentileschi's strategic motivations for her technical approach rather than what the shift in critical reception reveals about interpretive frameworks across time periods.
CThis restates the contrast between seventeenth-century and modern critical focus already described in the passage without drawing the inference about what this shift reveals.
DThis overgeneralizes the passage's note that Gentileschi's choices did not differ systematically from male contemporaries into a claim about all Baroque painters depicting female agency equally.
Question 14Hard
In the early twentieth century, many linguists believed that children acquired language primarily through imitation and reinforcement. However, linguist Noam Chomsky observed that children frequently produce grammatical constructions they have never heard before, such as novel past-tense forms following regular conjugation rules (e.g., "goed" instead of "went"). These errors occur across diverse linguistic communities and persist despite correction from adults. Furthermore, children master complex syntactic structures at ages when their general cognitive abilities remain limited. Based on these observations, Chomsky argued that _____
Which choice most logically completes the text?
Show the answer and explanation
Why B is right
The passage provides evidence that children produce novel grammatical forms, master complex syntax despite limited cognitive abilities, and resist adult correction. These observations led Chomsky to conclude that language acquisition cannot be explained by imitation and reinforcement alone, pointing instead to an innate biological capacity specialized for language.
Why the others are wrong
AThis choice merely restates evidence from the passage (that children produce novel constructions) rather than stating the conclusion Chomsky drew from that evidence.
CThis choice overgeneralizes by extending the claim to all cognitive domains, whereas Chomsky's argument based on the given evidence specifically concerns language acquisition.
DThis choice addresses teaching methods and grammar instruction, which is a different question from the one Chomsky was investigating about the fundamental nature of language acquisition.
Question 15Hard
Literary scholar Wai Chee Dimock argues that American literature should be understood not as bounded by national borders but as part of a planetary system of cultural exchange spanning millennia. She traces how Herman Melville's Moby-Dick incorporates elements from ancient Persian epic poetry, arguing that the novel's temporal reach extends far beyond nineteenth-century America. Similarly, Dimock demonstrates that contemporary Native American novelist Leslie Marmon Silko draws upon storytelling traditions predating European contact while simultaneously engaging with global postcolonial literature. For Dimock, these deep temporal and geographic connections reveal that _____
Which choice most logically completes the text?
Show the answer and explanation
Why B is right
Dimock's examples of American authors incorporating global and ancient influences support her broader argument that American literature should not be understood as nationally bounded. The logical inference is that isolating American literature from these planetary connections misrepresents how literature is actually produced.
Why the others are wrong
AThis restates the evidence about Melville and Silko incorporating diverse influences rather than drawing the methodological conclusion about how scholars should approach American literature.
CThis overgeneralizes Dimock's argument by suggesting no literary traditions can be distinguished at all, when she argues specifically against rigid national boundaries while still acknowledging traditions exist.
DThis addresses the relative importance of specific authors to different canons, but the passage concerns the theoretical framework for understanding all of American literature, not individual author significance.
Question 16Hard
Ecologist Maria Kovacs studied the foraging behavior of leaf-cutter ant colonies in response to simulated herbivore attacks on their fungus gardens. When Kovacs introduced a fungal pathogen that mimics damage from natural herbivores, colonies with more than 50,000 workers responded by expanding their foraging range by an average of 30 percent and targeting plant species with higher concentrations of antimicrobial compounds. Smaller colonies with fewer than 10,000 workers did not expand their foraging range but instead reduced fungus garden size by approximately 25 percent. Both response types successfully contained the pathogen spread, though larger colonies recovered their original garden size within three weeks while smaller colonies required eight weeks. This evidence suggests that _____
Which choice most logically completes the text?
Show the answer and explanation
Why A is right
The passage demonstrates that both large colonies (expansion strategy) and small colonies (reduction strategy) successfully contained the pathogen, indicating these are alternative effective approaches. The consistent correlation between colony size and strategy type logically supports the inference that colony size determines strategy deployment.
Why the others are wrong
BThis overgeneralizes the finding that larger colonies recovered in three weeks versus eight for smaller colonies into an absolute claim using 'invariably,' ignoring that both strategies were effective.
CThis merely summarizes the different responses of large versus small colonies already described in the passage without drawing the interpretive conclusion about multiple evolved strategies.
DThis addresses the foraging accuracy of workers in different colony sizes rather than the adaptive significance of having multiple pathogen-management strategies.
Question 17Hard
Musicologist David Rothstein has analyzed the compositional techniques Igor Stravinsky employed in his neoclassical period works of the 1920s and 1930s. Rothstein notes that Stravinsky frequently quoted melodic phrases from Baroque composers like Bach and Handel, but systematically displaced these phrases by several beats within the measure, disrupting their original metrical placement. Additionally, Stravinsky often reassigned these melodies to instrumental combinations foreign to Baroque practice—for instance, giving a phrase originally written for strings to a pair of bassoons. Rothstein argues that these techniques reveal that Stravinsky's engagement with earlier music was _____
Which choice most logically completes the text?
Show the answer and explanation
Why B is right
The passage describes systematic disruptions of original metrical placement and instrumental assignments, which are deliberate departures from the source material. These transformative techniques logically support Rothstein's argument that Stravinsky prioritized modern reinterpretation over faithful historical reproduction.
Why the others are wrong
AThis suggests faithfulness to historical practice, contradicting the evidence of systematic disruption and reassignment; it also addresses audience accessibility rather than compositional philosophy.
CThis restates the compositional techniques already detailed in the passage (quotation, metrical displacement, instrumental reassignment) without drawing Rothstein's interpretive conclusion about what these techniques reveal.
DThis extends the specific analysis of Stravinsky's techniques to a general claim about all neoclassical composers, an overgeneralization not supported by evidence focused on one composer.
Question 18Hard
Literary scholar Mei Chen has analyzed the narrative structure of Virginia Woolf's novel To the Lighthouse, noting that the central section, titled "Time Passes," compresses ten years into fewer than twenty pages while the sections before and after expand single days into over a hundred pages each. Chen observes that during this compressed middle section, major character deaths are mentioned only parenthetically, tucked into descriptions of the decaying house. In contrast, the expanded sections devote extensive passages to characters' moment-by-moment interior thoughts. Chen argues that this structural choice demonstrates that _____
Which choice most logically completes the text?
Show the answer and explanation
Why C is right
The passage establishes that Woolf expands moments of interior thought into extensive passages while compressing years of external events (including deaths) into brief, parenthetical mentions. This structural contrast logically supports Chen's argument that Woolf prioritized subjective psychological experience over external events.
Why the others are wrong
AThis merely describes the varying narrative pacing already detailed in the passage without drawing Chen's interpretive conclusion about what this structural choice reveals about Woolf's artistic priorities.
BThis extends the specific claim about Woolf's technique in one novel to a general claim about all modernist novelists, an overgeneralization not supported by the passage's evidence.
DThis addresses how characters experience time rather than what Woolf's narrative choices reveal about her artistic values, swapping the question from authorial technique to character psychology.
Question 19Hard
In the 1970s, paleontologist Stephen Jay Gould proposed that evolutionary change occurs in rapid bursts separated by long periods of stasis, a model he termed "punctuated equilibrium." Traditional Darwinian theory had emphasized gradual, continuous change. Recent examination of fossilized stickleback fish in a Nevada lake bed spanning 20,000 years reveals that body armor plates remained virtually unchanged for periods of 5,000 to 8,000 years, interrupted by intervals of only 100 to 200 years during which dramatic morphological shifts occurred. These brief transformation windows coincided with periods of documented volcanic activity that altered lake chemistry. The stickleback fossil record therefore suggests that _____
Which choice most logically completes the text?
Show the answer and explanation
Why B is right
The passage describes a pattern matching Gould's punctuated equilibrium model, where long stable periods were interrupted by rapid change coinciding with environmental disruption (volcanic activity). The logical completion connects this pattern to the broader principle that environmental changes can catalyze evolutionary shifts after stability.
Why the others are wrong
AThis overgeneralizes by claiming volcanic activity is the primary driver of all evolutionary change in aquatic species, when the evidence only shows correlation in one case of stickleback fish.
CThis merely restates the fossil evidence described in the passage rather than drawing the inference about what the pattern suggests regarding evolutionary mechanisms.
DThis addresses a different question about relative evolutionary rates between species, while the passage evidence supports a conclusion about the timing and triggers of change within one species.
Question 20Hard
In the early 20th century, physicist Marie Curie conducted pioneering research on radioactivity, isolating radium and polonium from uranium ore. Her work required processing tons of pitchblende, a labor-intensive undertaking that exposed her to high radiation levels for years. Modern analysis of Curie's laboratory notebooks reveals that the pages remain dangerously radioactive even today, over a century after she handled them. Furthermore, items from her personal effects—including her cookbooks and furniture—also emit detectable radiation. Given that Curie worked with radioactive materials daily and that common objects she touched retain radioactivity, scientists have inferred that _____
Which choice most logically completes the text?
Show the answer and explanation
Why D is right
The passage establishes that common objects Curie touched remain radioactive today, and that she worked with radioactive materials daily for years. The logical inference is that if her notebooks, cookbooks, and furniture absorbed and retained radioactive material, her body—in even more direct and prolonged contact with these materials—would have accumulated radiation as well.
Why the others are wrong
AThis restates evidence already provided (that her work involved handling radioactive materials that posed health risks) rather than drawing a new inference from it.
BThis overgeneralizes by extending the specific observation about Curie to all physicists studying radioactivity, which is not supported by the evidence given.
CThis addresses a different question (comparative quantity processed) rather than following the passage's logic about radiation accumulation in objects Curie contacted.
Question 21Hard
Art historian Linda Nochlin's essay "Why Have There Been No Great Women Artists?" challenged the assumption that biological or psychological differences explained women's underrepresentation in art history. Nochlin demonstrated that institutional barriers systematically excluded women from training: European art academies before 1900 prohibited women from life drawing classes, which were essential for mastering history painting, the most prestigious genre. Women were instead directed toward still life and portraiture, genres that required less institutional training but carried lower status. Nochlin noted that in regions where alternative training systems existed, such as seventeenth-century Bologna where women could study in family workshops, female artists like Elisabetta Sirani achieved recognition in history painting. This pattern indicates that _____
Which choice most logically completes the text?
Show the answer and explanation
Why A is right
Nochlin's evidence shows that where women gained institutional access through alternative systems, they succeeded in prestigious genres, while where they were excluded, they could not. This contrast supports the inference that institutional barriers, not ability differences, determined who could practice history painting.
Why the others are wrong
BThis restates the evidence about academy exclusions rather than drawing the broader conclusion about whether institutional access or innate factors determined artistic achievement.
CThis overgeneralizes Nochlin's argument by claiming biology has no influence whatsoever when she argues that institutional barriers were sufficient to explain the historical pattern, not that innate factors never matter.
DThis addresses Sirani's relative talent level compared to male peers, but Nochlin's argument concerns whether access rather than ability explains patterns, not individual talent rankings.
Question 22Hard
Art historian Linda Nochlin's 1971 essay "Why Have There Been No Great Women Artists?" challenged the premise of the question itself, arguing that institutional barriers rather than lack of talent explained women's historical absence from artistic canons. Nochlin detailed how women were barred from life-drawing classes essential to academic training and excluded from patronage networks. Her essay catalyzed the field of feminist art history. Recently, however, some scholars have argued that Nochlin's focus on access to institutions inadvertently reinforced the art world's existing hierarchies by accepting academic training and canonical recognition as measures of artistic merit. These scholars contend that many women artists worked outside institutional frameworks precisely to avoid restrictive conventions, and that their exclusion from canons reflected deliberate alternative practice rather than mere lack of access. This critique implies that _____
Which choice most logically completes the text?
Show the answer and explanation
Why A is right
The critique states that some women worked outside institutions deliberately and that their exclusion reflected alternative practice choices. The inference is that this choice to work outside institutional frameworks contributed to their marginalization in narratives organized around institutional measures of success.
Why the others are wrong
BThis misrepresents the critique, which doesn't deny institutional barriers existed but argues that focusing on them reinforced certain hierarchies. The inference concerns alternative practices, not the validity of Nochlin's barrier documentation.
CThis restates Nochlin's original argument rather than inferring what the recent critique implies about the relationship between institutional exclusion and deliberate alternative practice.
DThis overgeneralizes from 'some women artists' to 'all,' and assumes deliberate rejection rather than the multiple possible motivations the passage allows.
Question 23Hard
Paleobotanist Nan Crystal Arens analyzed fossilized leaves from the Cretaceous period to reconstruct ancient atmospheric carbon dioxide concentrations. Arens measured stomatal density—the number of pores per unit leaf area—in fossil specimens and compared these values to stomatal densities in living relatives of the fossilized species grown under controlled CO2 conditions. She found that leaves grown in high-CO2 environments consistently developed fewer stomata than genetically identical plants grown in low-CO2 conditions. When Arens applied this relationship to Cretaceous fossils dated to 100 million years ago, she calculated atmospheric CO2 levels substantially higher than previous models had estimated. This discrepancy suggests that _____
Which choice most logically completes the text?
Show the answer and explanation
Why B is right
Since Arens calculated CO2 levels substantially higher than previous models estimated, and since CO2 is a greenhouse gas, the logical inference is that climate models underestimated the warming effect during the Cretaceous. The passage provides evidence that challenges existing temperature reconstructions for that period.
Why the others are wrong
AThis restates the inverse relationship between stomatal density and CO₂ that was established earlier in the passage as evidence, not as the conclusion.
CThis overgeneralizes by claiming all previous methods were flawed when the passage only indicates a discrepancy with previous models, not that those models were fundamentally invalid.
DThis addresses what type of data leaves provide most accurately, but the passage concerns the implications of CO₂ findings for climate models, not for plant diversity research.
Question 24Hard
In the early 20th century, linguist Edward Sapir proposed that languages with grammatical gender systems (where nouns are classified as masculine, feminine, or neuter) might influence how speakers conceptualize objects. Recent experiments by cognitive scientist Lera Boroditsky tested this hypothesis by asking German and Spanish speakers to describe various objects. For items grammatically masculine in German but feminine in Spanish (such as "bridge"), German speakers tended to use adjectives like "strong" and "towering," while Spanish speakers preferred "elegant" and "slender." The pattern reversed for items with opposite gender assignments in the two languages, suggesting that _____
Which choice most logically completes the text?
Show the answer and explanation
Why B is right
Choice B is the best answer. The passage describes how German and Spanish speakers used different adjectives to describe the same objects based on the grammatical gender those objects have in their respective languages, with the pattern reversing when gender assignments reversed. This evidence supports the inference that grammatical gender influences object perception.
Why the others are wrong
AThis overgeneralizes the evidence by making a claim about all speakers of gendered versus non-gendered languages, when the passage only compares German and Spanish speakers.
CThis merely restates evidence already given in the passage rather than drawing a logical conclusion from it.
DThis addresses a related but different question about whether masculine gender always correlates with masculine qualities, rather than whether grammatical gender influences perception generally.
Question 25Hard
Art historian Linda Nochlin's influential 1971 essay "Why Have There Been No Great Women Artists?" argued that the absence of women from art history's canon resulted not from lack of talent but from institutional barriers. Nochlin noted that until the late 19th century, women were excluded from life-drawing classes—considered essential training—because propriety forbade their presence in rooms with nude models. Recent archival research by Germaine Greer has uncovered numerous accomplished paintings by 17th- and 18th-century women artists, but these works feature landscapes, still lifes, and portraits rather than the historical or mythological scenes with multiple figures that were most valued by academies and wealthy patrons. This finding suggests that _____
Which choice most logically completes the text?
Show the answer and explanation
Why B is right
Choice B is the best answer. The passage establishes that women were excluded from life-drawing training needed for figure work, and that discovered works by women artists feature genres not requiring such training rather than the figure-heavy historical scenes academies valued most, supporting the inference that the exclusion limited their work in valued genres.
Why the others are wrong
AThis addresses whether women preferred certain genres, which is a different question from whether institutional barriers prevented them from working in highly valued genres.
CThis merely restates the evidence about what genres women's discovered works represent rather than inferring why that pattern exists.
