Too narrow — captures one sentence, not the whole.
True of an adjacent entity in the passage, not the one asked about.
Plausibly true in reality, but unsupported by the text.
Question 1Hard
In José Saramago's 1995 novel "Blindness," an epidemic of white blindness strips characters of visual perception while leaving them conscious and mobile, creating a scenario in which social order rapidly disintegrates. Literary critic David Punter has interpreted this premise as an allegory for moral blindness, arguing that Saramago uses physical disability as a metaphor for ethical failure. However, disability studies scholar Rosemarie Garland-Thomson contends that such allegorical readings instrumentalize disability, treating it merely as a vehicle for meaning rather than engaging with the lived experience of disabled individuals. This critical tension highlights ongoing debates about whether metaphorical uses of disability in literature ultimately reinforce or challenge ableist assumptions.
Which choice best states the main idea of the text?
Show the answer and explanation
Why A is right
The passage presents two contrasting critical perspectives on Saramago's use of blindness—Punter's allegorical reading and Garland-Thomson's disability studies critique—and concludes by noting this tension reflects broader debates about whether metaphorical disability use reinforces or challenges ableist assumptions.
Why the others are wrong
BThis is too broad. The passage focuses specifically on conflicting interpretations of disability metaphor in Saramago's novel, not on contemporary literary criticism's treatment of marginalized groups generally.
CThis is too narrow. While Garland-Thomson's critique is mentioned, the main idea encompasses both critical perspectives and the broader debate about metaphorical uses of disability they represent.
DThis is plausible but not supported. The passage presents a debate about whether metaphorical uses reinforce or challenge ableist assumptions, but does not claim such works generally fail to represent disabled perspectives accurately.
Question 2Hard
In her 1962 novel The Golden Notebook, British author Doris Lessing employed a fragmented narrative structure that challenged conventional storytelling. The novel consists of four different-colored notebooks kept by the protagonist Anna Wulf, each recording a distinct aspect of her life: black for her experiences as a writer, red for political activities, yellow for fictionalized emotional experiences, and blue for a diary. These sections alternate with segments of a conventional novel titled Free Women. Through this structure, Lessing explored how individuals compartmentalize experience and the difficulty of achieving a unified sense of self in modern life.
According to the text, what is true about The Golden Notebook?
Show the answer and explanation
Why B is right
The passage explicitly describes four color-coded notebooks, each recording a distinct aspect of Anna Wulf's life, directly supporting the claim about color-designated sections corresponding to life domains.
Why the others are wrong
AWhile the passage mentions the structure challenged conventional storytelling, it does not claim the novel influenced all subsequent modernist fiction, making this too sweeping.
CThough the passage indicates Lessing explored psychological themes like compartmentalization, this describes the author generally rather than the novel specifically.
DThe passage does not suggest that fragmentation prevents understanding; rather, it states the structure explored compartmentalization of experience.
Question 3Hard
In the early twentieth century, Swedish geographer Sten De Geer proposed that urbanization patterns could be understood through the concept of "population potential," a measure combining population density with distance from major centers. While De Geer's framework gained some traction in Scandinavia, it was American geographer John Q. Stewart who transformed the idea into a rigorous quantitative model in the 1940s. Stewart's mathematical formulation, which treated population influence as analogous to gravitational force, became the foundation for spatial interaction theory and remains central to urban planning models today.
Which choice best states the main idea of the text?
Show the answer and explanation
Why B is right
The text traces how De Geer's concept gained limited traction until Stewart transformed it into a rigorous model that became foundational for urban planning, making this the unifying main idea across all sentences.
Why the others are wrong
AThe passage does not mention any criticism of Stewart's approach; it only describes his contribution positively.
CThis is too broad—the text specifically focuses on urbanization and urban planning, not 'various geographic phenomena.'
DThis captures only one detail about Stewart's model rather than the main idea about the concept's evolution from De Geer to Stewart.
Question 4Hard
Ecologist Maria Gonzalez's research on mycorrhizal networks has revealed that trees in temperate forests exchange carbon and nutrients through underground fungal connections. While earlier studies documented nutrient transfer between individual trees, Gonzalez demonstrated that these exchanges follow predictable patterns based on tree age and species. Older trees consistently allocate more carbon to younger saplings of the same species, particularly during periods of environmental stress. This finding has prompted forest management agencies to reconsider harvesting practices that remove mature trees, as doing so may compromise the survival of younger forest generations.
Which choice best states the main idea of the text?
Show the answer and explanation
Why B is right
The text describes how Gonzalez's research revealed predictable carbon allocation patterns from older to younger trees through mycorrhizal networks, and states that this discovery has led forest management agencies to reconsider their harvesting practices. Choice B captures both the research findings and their practical implications.
Why the others are wrong
AThis choice focuses only on one aspect mentioned in the text (networks facilitating exchanges) but misses the main point about the predictable patterns Gonzalez discovered and their management implications.
CThis statement is too broad, discussing ecosystems and sustainable forestry in general rather than the specific findings about mycorrhizal networks and their impact on policy.
DWhile the text discusses removing mature trees, it suggests this compromises younger tree survival rather than increasing carbon absorption capacity.
Question 5Hard
In her 1892 collection Iola Leroy, Frances Ellen Watkins Harper employed what literary historians now recognize as a deliberate narrative strategy: embedding overtly political speeches within the novel's dialogue. Unlike her contemporaries who favored subtle allegory, Harper allowed her characters to articulate explicitly abolitionist and pro-suffrage positions in extended monologues. Some early reviewers criticized this approach as didactic, yet Harper defended it in correspondence, arguing that the urgency of Reconstruction-era racial injustice demanded directness over artful indirection. Modern scholars note that this technique, while reducing certain aesthetic conventions of the period, created a documentary-like quality that preserved the intellectual discourse of African American activists in the 1890s.
According to the text, what is true about Harper's narrative approach in Iola Leroy?
Show the answer and explanation
Why A is right
The passage states Harper used 'overtly political speeches' and chose 'directness over artful indirection,' distinguishing her method from contemporaries who 'favored subtle allegory.'
Why the others are wrong
BThe text notes that 'some early reviewers criticized this approach as didactic,' indicating the reception was mixed, not universal praise.
CThe passage explicitly contrasts Harper's approach with that of 'contemporaries who favored subtle allegory,' stating she used direct political speeches instead.
DThe text indicates Harper's technique departed from 'certain aesthetic conventions of the period,' not that it reflected common practices among her peers.
Question 6Hard
Architectural historian Mabel O. Wilson has analyzed how the 1893 World's Columbian Exposition in Chicago used spatial organization to construct racial hierarchies. While the exposition's central White City showcased neoclassical architecture symbolizing progress and civilization, the midway featured ethnographic villages where non-European peoples were displayed as primitive spectacles. Wilson argues that this deliberate spatial segregation did not merely reflect existing racial ideologies but actively produced them, teaching millions of visitors to perceive cultural difference through an evolutionary framework. The exposition thus functioned as a pedagogical instrument, training observers in racialized ways of seeing that would persist long after the temporary structures were dismantled.
Which choice best states the main idea of the text?
Show the answer and explanation
Why C is right
The passage explains Wilson's argument that the exposition's spatial segregation between the White City and the midway did not just reflect but actively produced racial ideologies by training millions of visitors in racialized ways of perceiving cultural difference through an evolutionary framework.
Why the others are wrong
AThis is too narrow. While these architectural elements are mentioned, the main idea concerns Wilson's argument about how spatial organization actively constructed racial ideologies.
BThis is too broad. The passage focuses specifically on Wilson's analysis of how the 1893 exposition constructed racial hierarchies through spatial organization, not on exhibitions generally shaping attitudes.
DThis is plausible but not supported. The passage discusses how the ethnographic villages were part of a pedagogical system teaching racialized perspectives, but does not claim they provided first exposure to non-European practices.
Question 7Hard
Neuroscientist V.S. Ramachandran's research on phantom limb pain revealed that patients who had lost an arm or leg often experienced chronic pain in the missing limb due to conflicting sensory signals in the brain. To address this, Ramachandran developed mirror therapy, in which patients view a reflection of their intact limb positioned to appear in place of the missing one. When patients perform movements with the intact limb while watching its reflection, the visual feedback creates the illusion that the missing limb is moving without pain. This technique has been shown to reduce phantom limb pain in many patients by resolving the sensory conflict that the brain experiences.
According to the text, what is true about mirror therapy?
Show the answer and explanation
Why C is right
The passage states that mirror therapy creates the illusion that the missing limb is moving without pain, which matches the description of producing a visual perception of pain-free movement.
Why the others are wrong
AThe passage says the technique has reduced pain in many patients, not that it eliminated pain in all patients, making this claim too absolute.
BThough true that Ramachandran studied phantom limb pain, this describes the researcher's background rather than something about the therapy itself.
DThe passage describes using a mirror and watching movements, but does not mention neurofeedback training as a requirement.
Question 8Hard
The discovery of the Rosetta Stone in 1799 is often celebrated as the key that unlocked ancient Egyptian hieroglyphics. However, scholars now recognize that without Thomas Young's pioneering work identifying phonetic elements in the script and Jean-François Champollion's subsequent comprehensive decipherment, the stone would have remained merely a curious artifact. Champollion's mastery of Coptic proved essential in recognizing the linguistic connections between the ancient symbols and known languages, transforming what Young had begun into a complete system for reading hieroglyphics.
Which choice best states the main idea of the text?
Show the answer and explanation
Why C is right
Choice C is the best answer because the text explains that while the Rosetta Stone's discovery is celebrated, the scholarly work of both Young and Champollion was necessary to actually decipher hieroglyphics. The passage emphasizes that without their contributions, the stone would have been merely a curiosity.
Why the others are wrong
AThis choice misrepresents the passage's claim. The text doesn't diminish the stone's significance but rather emphasizes that additional scholarly work was required to realize its potential.
BThis choice focuses only on one aspect of Champollion's contribution mentioned in the final sentence, missing the broader point about both Young's and Champollion's combined contributions.
DThis choice is too broad, suggesting collaboration between Young and Champollion and extending beyond hieroglyphics to 'ancient languages' generally, neither of which the passage supports.
Question 9Hard
Linguist Deborah Tannen's analysis of conversational rituals reveals that speakers from different cultural backgrounds may interpret the same verbal behavior in contradictory ways. In her study of New York Jewish and California Christian communicative styles, Tannen found that overlapping speech, which New York participants understood as enthusiastic engagement, was perceived by California participants as aggressive interruption. This misalignment of interpretive frameworks, Tannen argues, can lead to negative judgments about interlocutors' character or intentions when the actual source of friction is divergent cultural expectations about conversational turn-taking. Her findings suggest that what appears to be interpersonal conflict may actually reflect systematic differences in discourse conventions.
Which choice best states the main idea of the text?
Show the answer and explanation
Why A is right
The text presents Tannen's finding that the same verbal behavior (overlapping speech) is interpreted differently by speakers from different cultural backgrounds, and argues that these divergent interpretations can be mistaken for interpersonal conflict. Choice A captures this main point about culturally specific interpretations leading to misunderstandings.
Why the others are wrong
BThis choice focuses only on the specific example used to illustrate Tannen's broader argument about cultural interpretation of conversational behavior.
CThe text discusses how cultural differences can be mistaken for interpersonal conflict but does not claim that cultural differences typically cause genuine conflicts.
DThis statement is too general and does not specifically address Tannen's argument about conversational rituals and interpretive frameworks.
Question 10Hard
Historian Patricia Lim has challenged conventional interpretations of the 1924 Immigration Act, which severely restricted immigration to the United States through national origin quotas. While most scholars emphasize the act's racial motivations and its devastating impact on Asian and Southern European immigration, Lim argues that economic anxieties following World War I played a more central role than previously acknowledged. She points to congressional testimony from labor unions and industrial organizations, both of which expressed concerns about wage depression and unemployment. Lim does not dismiss the racial prejudice evident in the act's design, but she contends that economic factors provided the political momentum that made such discriminatory legislation possible.
Which choice best states the main idea of the text?
Show the answer and explanation
Why D is right
Choice D is the best answer. The text presents Lim's argument that economic factors played a more central role than previously acknowledged in the passage of the 1924 Immigration Act, while not dismissing racial motivations. This accurately captures the main point of the passage.
Why the others are wrong
AThis is too broad. The text focuses specifically on Lim's particular argument about economic factors, not on the general scholarly debate about the act.
BThis is too narrow. The congressional testimony is presented as evidence supporting Lim's broader argument about economic anxieties, not as the main point itself.
CThis overstates Lim's position. The text says economic factors were 'more central' than previously acknowledged and provided 'political momentum,' but Lim explicitly does not dismiss racial prejudice. She argues for the importance of economic factors, not their dominance over racial ones.
Question 11Hard
Political scientist Erica Chenoweth's quantitative analysis of resistance movements from 1900 to 2006 revealed that nonviolent campaigns achieved their objectives 53 percent of the time, compared to 26 percent for violent insurgencies. Chenoweth attributes this disparity not to moral superiority but to tactical advantages: nonviolent movements can recruit more broadly across demographics, maintain internal cohesion more easily, and impose lower costs on potential defectors from the regime. These findings challenge the widespread assumption that violence is inherently more effective than nonviolence in asymmetric conflicts, suggesting instead that strategic considerations should guide movement tactics.
Which choice best states the main idea of the text?
Show the answer and explanation
Why C is right
The passage presents Chenoweth's findings that nonviolent campaigns succeed more often than violent ones, explains this difference through tactical advantages rather than morality, and notes these findings challenge assumptions about violence's effectiveness in asymmetric conflicts.
Why the others are wrong
AThis is too broad. The passage compares nonviolent versus violent approaches specifically, not diverse tactics versus single approaches generally.
BThis is too narrow. While this statistic is mentioned, the main idea includes the comparison to violent movements, the explanation through tactical advantages, and the challenge to assumptions about violence.
DThis is plausible but not supported. The passage explicitly states Chenoweth attributes the disparity to tactical advantages, not moral superiority, and does not claim moral principles contribute to participant recruitment.
Question 12Hard
Geophysicist Miaki Ishii has developed seismic imaging techniques that reveal previously undetected structures in Earth's inner core. By analyzing the travel times of seismic waves that pass through the planet's center, Ishii identified patterns suggesting the inner core contains a distinct innermost region with differently oriented iron crystals. Traditional models treated the inner core as relatively homogeneous, but Ishii's findings indicate it may have grown in stages, with each layer recording different conditions in Earth's thermal history. These results imply that the inner core functions not merely as a stable anchor for the geodynamo, but as an archive preserving information about planetary evolution across billions of years.
Which choice best states the main idea of the text?
Show the answer and explanation
Why B is right
The passage explains how Ishii's seismic imaging revealed a complex inner core structure with distinct layers recording Earth's thermal history, contrasting with traditional homogeneous models, and concludes the inner core functions as an archive of planetary evolution.
Why the others are wrong
AThis is too broad. The passage focuses specifically on Ishii's findings about inner core structure, not on seismic imaging as a method across geological disciplines generally.
CThis is too narrow. While this detail about methodology and findings is mentioned, the main idea includes the contrast with traditional models and the implication that the inner core archives Earth's thermal history.
DThis is plausible but not supported. The passage mentions the inner core functions not merely as a geodynamo anchor but as an archive, but does not argue its influence on the geodynamo itself is more complex than recognized.
Question 13Hard
In her analysis of nineteenth-century British literature, scholar Amelia Patterson challenges the conventional view that industrialization uniformly inspired pessimism among Victorian novelists. While canonical works by authors such as Charles Dickens and Elizabeth Gaskell certainly depicted the harsh conditions of factory life, Patterson identifies a parallel tradition of industrial optimism in lesser-known novels of the period. Writers like Harriet Martineau and Dinah Mulock Craik portrayed factories and railways as engines of social progress, emphasizing themes of technological innovation and economic opportunity. Patterson argues that literary historians have overlooked these optimistic narratives because they clash with the dominant critical framework that views Victorian literature primarily as social protest. By recovering these marginalized texts, Patterson suggests that the Victorian literary response to industrialization was more ideologically diverse than scholars have generally recognized.
Which choice best states the main idea of the text?
Show the answer and explanation
Why A is right
Choice A is the best answer. The text presents Patterson's argument that Victorian literary responses to industrialization included both critical and optimistic perspectives, and that scholars have overlooked this diversity by focusing primarily on protest literature.
Why the others are wrong
BThis is too narrow. The comparison between specific authors is mentioned as evidence for Patterson's broader argument about the diversity of Victorian literary responses, not as the main point itself.
CThis is too broad. The text focuses specifically on Patterson's argument about the diversity of responses to industrialization in Victorian literature, not on general patterns of how Victorian novelists responded to social changes.
DThis overstates the claim. Patterson suggests that historians have 'overlooked' these texts because they 'clash with the dominant critical framework,' but the text does not characterize this as systematic bias or as the main point of Patterson's work. Her main contribution is identifying the diversity of responses.
Question 14Hard
In 1889, astronomer E. E. Barnard discovered Jupiter's moon Amalthea using direct visual observation through a telescope, making it the last planetary satellite to be found without photographic aid. While this achievement demonstrated the potential of human vision in astronomical discovery, the subsequent century saw photography become the dominant method for celestial detection. Modern digital imaging has extended this trend further, with computer algorithms now identifying celestial objects that would be imperceptible to both photographic plates and human observers, effectively rendering Barnard's observational technique obsolete in contemporary astronomy.
Which choice best states the main idea of the text?
Show the answer and explanation
Why A is right
The passage traces how Barnard's 1889 visual discovery of Amalthea marked the end of an era, followed by photography's dominance and then digital imaging's ascendance, making his technique obsolete. This historical arc of changing detection methods unified by Barnard's discovery as a turning point is the main idea.
Why the others are wrong
BThis is too broad. The passage specifically discusses astronomical detection methods, not scientific methodology across multiple disciplines.
CThis is too narrow. While Amalthea's discovery is mentioned, the passage's focus is on the broader shift in detection methods that this discovery represented.
DThis is plausible but not supported. The passage notes that digital imaging identifies objects imperceptible to photography, but does not argue for the superiority of one method over another.
Question 15Hard
Astrophysicist Elena Vasquez has proposed a controversial explanation for the unexpected brightness of certain distant galaxies observed by the James Webb Space Telescope. These galaxies, which formed less than 500 million years after the Big Bang, appear far more luminous than theoretical models predict for such early cosmic structures. While some researchers have suggested that the models themselves require revision, Vasquez argues that the galaxies' brightness may result from an unusually high rate of supermassive black hole formation during this period. Her calculations indicate that if these early galaxies contained black holes with masses exceeding one million solar masses, the intense radiation from matter falling into these black holes could account for the excess luminosity. However, this explanation raises its own puzzle: current models cannot easily explain how black holes of such size could form so rapidly after the universe's beginning.
Which choice best states the main idea of the text?
Show the answer and explanation
Why B is right
Choice B is the best answer. The text presents Vasquez's explanation for the brightness of early galaxies—supermassive black holes—and notes that while this could account for the observations, it raises the question of how such black holes could form so quickly.
Why the others are wrong
AThis is too broad. While the text mentions that the galaxies challenge models, the main focus is on Vasquez's specific proposal about black holes and the complications this explanation introduces.
CThis is too narrow. This detail about radiation is part of Vasquez's explanation but does not capture the main point about her proposed solution and its attendant puzzle.
DThis is not supported by the text. The passage mentions that 'some researchers' have suggested model revision, but it does not claim that most astrophysicists agree on this point. The text focuses on Vasquez's alternative explanation.
Question 16Hard
The ancient city of Great Zimbabwe, which flourished between the 11th and 15th centuries, was long attributed by colonial scholars to foreign civilizations, reflecting a refusal to credit indigenous Africans with advanced architectural achievement. Archaeological evidence, however, has conclusively established that the Shona people built the massive stone structures using sophisticated dry-stone techniques requiring no mortar. Radiocarbon dating of artifacts and analysis of construction methods confirm continuous local development. This reattribution represents more than historical correction; it challenges persistent assumptions about technological innovation in precolonial Africa.
Which choice best states the main idea of the text?
Show the answer and explanation
Why C is right
Choice C is the best answer because the passage emphasizes both the archaeological correction of Great Zimbabwe's origins to the Shona people and the broader significance of this correction in challenging colonial assumptions about African technological capacity.
Why the others are wrong
AThis choice focuses too broadly on archaeological methods improving understanding of African civilizations generally, rather than the specific correction and its implications discussed in the passage.
BThis choice makes a comparative claim about the Shona techniques that the passage does not support. The text describes the techniques as sophisticated but does not compare them to contemporaneous methods elsewhere.
DThis choice captures only a specific detail about construction technique, missing the passage's emphasis on the correction of historical misattribution and its broader significance.
Question 17Hard
Soil microbiologist Joanne Emerson has investigated how microbial communities in wine-producing regions contribute distinct flavor profiles to wines, a phenomenon known as microbial terroir. While winemakers have long attributed regional wine characteristics to soil composition and climate, Emerson's research reveals that indigenous yeast populations harbor region-specific genetic variations affecting fermentation chemistry. These microbial differences persist across growing seasons despite vineyard management practices, suggesting that preserving native microbial diversity may be as essential to maintaining wine distinctiveness as preserving soil conditions or grape varietals.
Which choice best states the main idea of the text?
Show the answer and explanation
Why B is right
The passage discusses how Emerson's findings on microbial terroir reveal that region-specific yeast populations affect wine flavor through genetic variations, and concludes that preserving these microbial communities may be as important as other factors in maintaining wine distinctiveness.
Why the others are wrong
AThis is too broad. The passage focuses specifically on microbial contributions to wine characteristics, not on agricultural products generally or multiple environmental factors in combination.
CThis is too narrow. While this detail is mentioned, the main idea encompasses the broader significance of these findings for understanding and preserving wine distinctiveness.
DThis is plausible but not supported. The passage states winemakers attributed characteristics to soil and climate, but does not argue they overestimated soil's importance.
Question 18Hard
The Harlem Renaissance of the 1920s is widely recognized for its literary achievements, but the movement's impact on visual arts deserves equal attention. Painter Aaron Douglas pioneered a distinctive style that merged African artistic traditions with Art Deco modernism, creating powerful imagery that celebrated Black identity and culture. His murals and illustrations appeared in prominent publications and public spaces, making avant-garde aesthetics accessible to broader audiences. By demonstrating that African American artists could innovate within modernist frameworks while maintaining cultural specificity, Douglas challenged the period's artistic hierarchies and expanded the movement's cultural reach beyond literature.
Which choice best states the main idea of the text?
Show the answer and explanation
Why B is right
Choice B is the best answer because the passage argues that Douglas's work, through its innovative fusion and wide accessibility, challenged artistic hierarchies and expanded the Harlem Renaissance's impact beyond its literary reputation, which is the text's central claim.
Why the others are wrong
AThis choice is too broad, making a general claim about the Harlem Renaissance that misses the passage's specific focus on how Douglas's visual art contributions expanded and challenged the movement.
CThis choice makes a comparative claim about Douglas's prominence versus other visual artists that the passage does not support. The text mentions his work appeared prominently but does not compare him to others.
DThis choice describes only Douglas's style, omitting the passage's emphasis on how his work challenged hierarchies and expanded the movement's cultural reach.
Question 19Hard
Archaeologist Jennifer Chen's excavations at a Neolithic site in northern China have revealed an unexpected pattern in ceramic production. The site contains two distinct pottery workshops dating to approximately 3000 BCE, located only 200 meters apart. Chemical analysis of clay samples shows that one workshop used locally sourced materials while the other imported clay from a riverbed 15 kilometers away. Surprisingly, the imported clay offered no apparent technical advantages—both clay types yielded similarly durable vessels when fired. Chen proposes that the use of non-local clay may have served a social function, perhaps signaling elite status or ceremonial purpose. This interpretation challenges the assumption that Neolithic craft specialization was driven primarily by efficiency and resource optimization.
Which choice best states the main idea of the text?
Show the answer and explanation
Why A is right
Choice A is the best answer. The text presents Chen's findings about two workshops using different clay sources and her interpretation that non-local clay may have served social functions, challenging assumptions about resource optimization as the primary driver of material choice.
Why the others are wrong
BThis is too broad. The text focuses on Chen's specific site and her interpretation about material choice, not on comparing Neolithic Chinese craft specialization to other societies.
CThis is too narrow. While this fact is mentioned, it serves as evidence for the larger point about social versus technical motivations for material choice.
DThis overstates what the text supports. Chen 'proposes' that non-local clay 'may have' served social functions, but this is presented as an interpretation, not as an established fact about desirability or status.
Question 20Hard
Political theorist Adom Getachew has reinterpreted the mid-twentieth-century decolonization movement as an attempt to fundamentally reshape international order rather than simply achieve national sovereignty. While conventional accounts emphasize newly independent nations' desire for self-determination within existing international institutions, Getachew's analysis of anticolonial thinkers like Kwame Nkrumah and Julius Nyerere reveals a more ambitious vision. These leaders advocated for a postimperial world order built on principles of economic redistribution, collective self-reliance, and shared sovereignty. Their proposals for institutions like the New International Economic Order, Getachew argues, represented a coherent alternative to both Western liberal internationalism and Soviet-style socialism, though this worldmaking project ultimately foundered on resistance from former colonial powers.
Which choice best states the main idea of the text?
Show the answer and explanation
Why B is right
The text contrasts conventional accounts of decolonization with Getachew's reinterpretation, describes the ambitious vision of anticolonial thinkers she analyzes, and notes that this worldmaking project represented a coherent alternative to existing systems. Choice B accurately captures Getachew's main argument.
Why the others are wrong
AThis detail describes one element of the anticolonial vision Getachew analyzes but does not capture her broader argument about reinterpreting decolonization as worldmaking.
CWhile the text mentions that the project foundered, this is not presented as the main idea, which concerns Getachew's reinterpretation of anticolonial ambitions.
DThis statement is too general about methodology and does not specifically address Getachew's argument about the worldmaking dimension of decolonization.
Question 21Hard
Mycorrhizal networks, often called the "wood wide web," are fungal connections that link the root systems of multiple trees in a forest. Recent research by Suzanne Simard has revealed that these networks facilitate nutrient transfer between trees, with mature trees sometimes channeling resources to younger saplings. However, the extent to which this transfer represents intentional allocation versus passive overflow of excess nutrients remains contested. Simard argues that the patterns observed suggest active resource management, while critics maintain that the evidence is equally consistent with non-selective diffusion processes.
Which choice best states the main idea of the text?
Show the answer and explanation
Why A is right
Choice A is the best answer because it captures both the established fact that mycorrhizal networks transfer nutrients and the central debate about whether this transfer is intentional or passive, which the passage emphasizes through Simard's position and her critics' alternative interpretation.
Why the others are wrong
BThis choice is too broad, extending beyond the specific debate about mycorrhizal networks to ecological processes generally, which the passage does not address.
CThis choice overstates the passage's claim. The text indicates that Simard argues for active management but notes that critics contest this interpretation, so it has not been proven.
DThis choice mentions only the existence of mycorrhizal networks, omitting the passage's main focus on the debate about how nutrient transfer through these networks operates.
Question 22Hard
Ecologist Karen C. Abbott's mathematical models of predator-prey dynamics have revealed that environmental noise—random fluctuations in temperature, precipitation, or resource availability—can stabilize population cycles that would otherwise exhibit chaotic behavior. In deterministic models, certain parameter combinations produce population trajectories so sensitive to initial conditions that long-term prediction becomes impossible. However, Abbott's stochastic models demonstrate that moderate environmental variability can paradoxically reduce this sensitivity, constraining populations within predictable bounds. This finding complicates the conventional view that environmental stability promotes ecosystem predictability, suggesting instead that some degree of fluctuation may be necessary for reliable ecological forecasting.
Which choice best states the main idea of the text?
Show the answer and explanation
Why B is right
The passage explains Abbott's finding that environmental noise can stabilize otherwise chaotic population dynamics, and concludes this complicates the view that environmental stability promotes predictability, suggesting fluctuation may aid forecasting.
Why the others are wrong
AThis is plausible but not supported. The passage actually argues the opposite: that environmental fluctuations can reduce chaos and make populations more predictable by constraining them within bounds.
CThis is too broad. The passage focuses on Abbott's specific findings about environmental noise in predator-prey dynamics, not on mathematical modeling's importance in ecology generally.
DThis is too narrow. While this point is mentioned, the main idea encompasses Abbott's finding that environmental noise stabilizes these chaotic dynamics and the implication for views on environmental stability.
Question 23Hard
Art historian Rachel Okonkwo has reexamined the traditional interpretation of Jan van Eyck's 1434 painting The Arnolfini Portrait, which depicts a wealthy merchant and his wife in an ornate interior. For centuries, scholars viewed the work as a straightforward wedding portrait, citing symbolic elements such as the joined hands and the presence of a small dog, traditionally associated with marital fidelity. However, Okonkwo argues that the painting's purpose was primarily legal rather than ceremonial. She points to the elaborate signature van Eyck inscribed on the back wall—'Jan van Eyck was here'—along with the mirror reflecting two witnesses, as evidence that the painting functioned as a visual contract documenting a business agreement or property transfer. While Okonkwo acknowledges that the painting incorporates domestic and marital imagery, she maintains that these elements served to legitimize the legal transaction rather than celebrate a marriage.
Which choice best states the main idea of the text?
Show the answer and explanation
Why A is right
Choice A is the best answer. The text presents Okonkwo's argument that the painting's primary purpose was legal documentation rather than celebration of a marriage, which challenges the traditional interpretation. This captures the main point unifying all the details in the passage.
Why the others are wrong
BThis is too narrow. These specific details are presented as evidence supporting Okonkwo's broader argument about the painting's legal function, not as the main idea themselves.
CThis is too broad. The text focuses specifically on Okonkwo's reinterpretation of this particular painting, not on general trends in Renaissance art interpretation.
DThis is not supported by the text. The passage presents Okonkwo's view as a challenge to the traditional interpretation held 'for centuries,' not as a consensus view now accepted by most scholars.
Question 24Hard
Ecologist Marcus Thompson has been investigating the role of mycorrhizal networks—underground fungal connections between plant roots—in forest ecosystem resilience. His research in temperate forests has shown that these networks allow trees to transfer carbon, nutrients, and even chemical defense signals to one another. In one experiment, Thompson's team stressed Douglas fir seedlings by depriving them of light, then measured resource transfer from nearby established trees through the mycorrhizal network. The seedlings receiving resources through the network showed a 26 percent higher survival rate than isolated seedlings. However, Thompson notes that the benefits appear asymmetrical: mature trees transfer resources to seedlings more readily than to other mature trees, suggesting that mycorrhizal networks may function more as parental care systems than as generalized mutual aid networks.
Which choice best states the main idea of the text?
Show the answer and explanation
Why A is right
Choice A is the best answer. The text describes Thompson's research on mycorrhizal networks and emphasizes his finding that resource transfer is asymmetrical, flowing more from mature trees to seedlings, which suggests a parental care function rather than generalized mutual aid.
Why the others are wrong
BThis is too broad. The text focuses specifically on Thompson's findings about asymmetrical resource transfer, not on the general prominence of mycorrhizal research in ecology.
CThis is too narrow. The survival rate finding is presented as evidence for the broader point about how mycorrhizal networks function, particularly regarding asymmetrical resource transfer.
DThis is not supported by the text. The passage does not compare mycorrhizal transfer to direct root contact or make claims about which method accounts for 'most' resource transfer.
Question 25Hard
In Toni Morrison's novel "Beloved," the character of Sethe is haunted both literally, by the ghost of her deceased daughter, and figuratively, by memories of enslavement. Critics have interpreted this dual haunting as Morrison's exploration of how trauma persists across generations. The novel's fragmented narrative structure, which moves unpredictably between time periods, mirrors the intrusive nature of traumatic memory. By refusing linear chronology, Morrison suggests that the past is not simply behind us but continually resurfaces, demanding acknowledgment. This technique has influenced subsequent writers addressing historical trauma, establishing a literary vocabulary for representing experiences that resist conventional storytelling.

Show the answer and explanation
Why A is right
Choice A is the best answer because the passage emphasizes how Morrison's fragmented structure both represents traumatic memory's intrusive nature and has influenced subsequent writers, establishing this technique's significance beyond the novel itself.
Why the others are wrong
BThis choice focuses only on describing Sethe's haunting, which is merely the opening detail the passage uses to introduce its main point about narrative structure and influence.
CThis choice makes an evaluative claim about narrative effectiveness that the passage does not argue. The text describes what Morrison's structure achieves but does not claim it is more effective than linear chronology.
DThis choice is too broad and vague, referring generally to contemporary writers and new techniques rather than the passage's specific focus on Morrison's influence through her nonlinear approach.
