25 hard SAT Command of Evidence — Textual questions

Which quotation from a report on Inca agriculture most effectively illustrates Rodriguez's claim?

• A"The terraces, constructed with precisely fitted stones and advanced drainage systems, prevented soil erosion on steep mountain slopes and have remained structurally sound for over five centuries."
• B"Archaeological evidence indicates that terrace construction required enormous labor investment, with some estimates suggesting that building the terraces at Moray alone involved moving over 10000 cubic meters of earth."
• C"Recent studies show that terrace depth and orientation created temperature variations of up to 15 degrees Celsius between levels, allowing simultaneous cultivation of lowland maize and highland quinoa on the same mountainside—crops that naturally grow 2000 meters apart in elevation."
• D"Most Inca terraces were situated in valleys and on hillsides where rainfall and soil conditions were already favorable for agriculture, suggesting that the empire's food production remained constrained by natural environmental factors."

Which quotation from Okoro's research most effectively illustrates this claim?

• A"King Moshoeshoe I of the Basotho people successfully resisted Boer expansion through a series of military campaigns in the 1850s and 1860s, maintaining his kingdom's independence through armed conflict."
• B"Emperor Menelik II of Ethiopia imported European firearms and hired European military advisors to train his army, but simultaneously required all diplomatic communications to be conducted in Amharic and structured his imperial administration according to traditional Ethiopian principles, enabling him to defeat Italian invasion forces while maintaining indigenous governance systems."
• C"Many African societies in the nineteenth century possessed sophisticated political institutions and diplomatic traditions that predated European contact."
• D"Some African rulers in coastal regions established trade relationships with European merchants and allowed missionary activity within their territories during the nineteenth century."

Which quotation from Chen's research most effectively illustrates this claim?

• A"Fossil evidence shows that mosasaurs and plesiosaurs disappeared from the fossil record at precisely the same geological boundary as non-avian dinosaurs, supporting the hypothesis of a single catastrophic extinction event."
• B"Analysis of sediment cores reveals that volcanic emissions increased ocean acidity by 0.3 pH units over two million years preceding the impact, and during this same period, fossilized remains of large marine reptiles become progressively scarcer and exhibit signs of nutritional stress."
• C"The diversity of marine reptile species in the late Cretaceous was remarkable, with over forty distinct genera inhabiting oceans across the globe."
• D"Volcanic activity in the Deccan Traps region released substantial amounts of sulfur dioxide and carbon dioxide into the atmosphere during the final million years of the Cretaceous period."

Which quotation from Soledad's study most effectively illustrates her claim?

• A"The textiles produced by Quechua weavers demonstrate exceptional technical skill, with some pieces containing over fifty distinct colors derived from natural dyes."
• B"Elder weaver Rosa Condori explained that the zigzag pattern in blue and yellow on her textile indicates the timing of the potato harvest in a year of unusual rainfall, while the adjacent diamond shapes record the number of community members who participated."
• C"Many contemporary Quechua weavers have begun incorporating non-traditional patterns borrowed from commercial textile designs, leading some anthropologists to worry about the loss of cultural heritage."
• D"The geometric patterns found in Quechua textiles bear striking resemblance to those used by other Andean cultures, suggesting a shared aesthetic tradition across the region."

Which quotation from a study of pulsar rotation would be the most effective evidence for Tanaka to include in support of this claim?

• A"Theoretical models demonstrate that mass accretion from a companion star can spin up a neutron star to rotation rates approaching 700 revolutions per second, consistent with the speeds observed in the fastest known pulsars."
• B"Observations of PSR J1748-2446ad reveal that it is located in a globular cluster where the stellar density is high enough to make neutron star mergers statistically more likely than in typical galactic environments."
• C"Calculations indicate that accretion sufficient to spin PSR J1748-2446ad to 716 revolutions per second would require transferring 0.4 solar masses over 2 billion years, but spectroscopic analysis shows the companion star has lost only 0.2 solar masses, while neutron star merger simulations predict post-merger rotation rates of 400-500 revolutions per second from angular momentum transfer alone."
• D"PSR J1748-2446ad emits regular pulses of electromagnetic radiation as it rotates, a characteristic feature shared by all pulsars regardless of their formation history."

Which quotation from a legal analysis most effectively illustrates Brown's claim?

• A"Disability rights legislation has significantly improved accessibility in public spaces and workplaces over the past three decades."
• B"To qualify for workplace accommodations under disability law, employees must obtain medical documentation certifying their impairments and must continually assert their status as disabled persons, a process that reifies disability as an essential identity rather than addressing the social organization of work that produces disabling conditions."
• C"Many advocacy organizations have argued that disability rights protections remain inadequately enforced despite their formal legal recognition."
• D"Legal scholars have debated whether rights-based approaches or redistributive policies more effectively address social inequality."

Which quotation from a scientific paper most directly supports McElwain's hypothesis?

• A"Geological evidence indicates that volcanic activity during the late Triassic was widespread across multiple continents, though the precise timing of eruptions relative to the extinction remains difficult to establish."
• B"Analysis of sedimentary rock layers from the Triassic-Jurassic boundary reveals a sharp increase in carbon isotope ratios consistent with massive volcanic carbon dioxide release, coinciding with marine fossil records showing widespread species collapse and evidence of ocean acidification."
• C"While volcanic eruptions occurred during the late Triassic, the extinction pattern shows regional variation suggesting that local environmental factors, rather than a single global catastrophe, determined which species survived."
• D"Fossil plant remains from Triassic deposits show morphological changes in leaf structure that occurred over several million years, indicating gradual climate shifts during the period."

Which quotation from a research study would most effectively illustrate Okonkwo's claim?

• A"Deep-sea anglerfish use bioluminescent lures to attract prey in the lightless environment of the abyssal zone, demonstrating that light production serves a clear predatory function in these organisms."
• B"Observations of the hatchetfish Argyropelecus hemigymnus reveal that individuals produce species-specific bioluminescent flash patterns at regular intervals throughout the year, with frequency increasing threefold during spawning season, while energy expenditure measurements show light production accounts for 18 percent of the organism's total metabolic budget—an unsustainable cost if displays occurred only during infrequent predatory or defensive episodes."
• C"Bioluminescence has evolved independently in multiple deep-sea lineages, suggesting that light production confers significant adaptive advantages in lightless marine environments."
• D"Several deep-sea species display bioluminescent patterns during mating season, indicating that light production may play some role in reproductive behavior, though its primary functions likely remain predatory and defensive."

Which finding from developmental research would most directly support Gopnik's claim?

• A"Cross-cultural studies reveal that children in all human societies engage in pretend play and hypothesis-testing behaviors during early childhood, activities that have no immediate survival value but correlate strongly with later ability to learn complex cultural skills."
• B"Neurological research demonstrates that human brain development continues well into adolescence, with the prefrontal cortex reaching full maturation only in the early twenties."
• C"Comparative studies show that while young chimpanzees can learn tool use through observation, they typically master only the specific techniques they observe rather than generating novel variations or improvements."
• D"Research indicates that human children who assume adult responsibilities at early ages due to economic necessity often develop practical skills rapidly, suggesting that extended childhood is not essential for acquiring complex abilities."

Which quotation from a review of Passing most effectively illustrates McDowell's claim?

• A"Larsen's novel provides a nuanced examination of the psychological costs of racial passing, as protagonist Irene Redfield wrestles with her feelings about her childhood friend Clare Kendry's decision to pass as white."
• B"The novel's ambiguous ending, in which Clare falls from a window during a confrontation, has generated extensive critical debate about whether her death was accident, suicide, or murder."
• C"Throughout the novel, Irene's ostensible anxiety about Clare's racial passing is expressed through language of fascination and attraction; passages describing Clare's appearance and Irene's inability to resist her are structured as seduction scenes, while actual discussion of racial identity remains curiously superficial and abstract."
• D"Passing explores the complex social dynamics of the Harlem Renaissance, depicting both the vibrant cultural life of Black intellectuals and the rigid racial boundaries that constrained their opportunities."

Which quotation from a research study would most effectively illustrate Valdez's claim?

• A"Across fifteen study sites with identical climate conditions and pesticide exposure, bee populations in fragmented habitats showed 67% lower colony survival rates compared to populations in continuous habitat zones of equivalent total area."
• B"Temperature increases of 2 degrees Celsius correlated with a 34% reduction in bee populations, while pesticide exposure at current agricultural levels reduced populations by 41%, suggesting these factors work synergistically."
• C"Bee populations declined in both fragmented and continuous habitats over the study period, indicating that multiple environmental stressors affect these insects regardless of landscape configuration."
• D"Habitat fragmentation affects numerous pollinator species, including butterflies and hoverflies, which also require connected landscapes for successful reproduction and foraging activities."

Which quotation from a study of resource management most effectively illustrates Ostrom's claim?

• A"In the Swiss alpine meadows studied, villages have maintained communal grazing lands for over five centuries without degradation."
• B"Interviews revealed that community members universally understood the importance of sustainable harvesting practices and expressed commitment to preserving resources for future generations."
• C"Government intervention in 1985 to formalize grazing regulations disrupted traditional management systems, leading to conflicts and overgrazing that had not occurred under community self-governance."
• D"The irrigation system operates through elected water monitors who allocate rotation schedules, conduct monthly inspections, and impose escalating fines—starting at half a day's wages for first violations—on users who take water out of turn or damage infrastructure, with violators themselves participating in collective decisions about penalty modifications."

Which quotation from a research article would most directly support the claim that Bassler's findings reshape our understanding of bacterial behavior?

• A"Bassler's work has identified over twenty distinct chemical signals that different bacterial species use to communicate, expanding our catalog of known quorum sensing molecules."
• B"Before Bassler's research, scientists recognized that bacteria could respond to environmental changes, but they assumed these responses were triggered by individual detection rather than coordinated group sensing."
• C"While Bassler has shown that bacteria communicate chemically, most bacterial activities—including nutrient absorption and reproduction—continue to function independently of population density."
• D"Bassler's experiments demonstrate that bacterial communication occurs primarily in laboratory settings, with limited evidence that such coordination happens in natural environments where bacteria face different selective pressures."

Which quotation from an analysis of Villa-Lobos's music most effectively illustrates Vargas's claim?

• A"Villa-Lobos's Bachianas Brasileiras series successfully merges the contrapuntal techniques of Johann Sebastian Bach with melodies inspired by Brazilian folk songs, demonstrating the composer's mastery of both traditions."
• B"In his String Quartet No. 5, Villa-Lobos employs what initially appears to be sonata form, but detailed analysis reveals that the work's development section follows the call-and-response pattern of choro music, with thematic transformation governed by improvisational principles rather than Germanic motivic development."
• C"Villa-Lobos spent much of his youth traveling through rural Brazil, collecting folk songs and studying the musical practices of Indigenous communities."
• D"The composer's works frequently feature rhythmic complexity and syncopation characteristic of Brazilian popular music, setting them apart from the works of his European contemporaries."

Which quotation from a scholarly article would most directly support Long's claim?

• A"The printing press enabled scientific treatises to reach scholars across the continent within months rather than years, fundamentally transforming the pace of intellectual exchange."
• B"Early printed editions of Ptolemaic astronomical tables contained calculation errors that were mechanically reproduced in thousands of copies, and readers were less inclined to correct printed pages than they had been to annotate manuscripts."
• C"While manuscript copying introduced variation and occasional errors, the standardization achieved through print actually improved the reliability of scientific texts by ensuring consistency across copies."
• D"The printing press did reproduce some inaccuracies from earlier sources, but it also enabled the publication of new experimental findings that challenged classical authorities."

Which quotation from a review of Dreams of Trespass most effectively illustrates Hassan's claim?

• A"Mernissi's vivid descriptions of her childhood in Fez provide readers with an intimate portrait of daily life in a traditional Moroccan household during the 1940s."
• B"The memoir traces Mernissi's personal journey from a restricted childhood within the walls of her family's home to her eventual emergence as an internationally recognized sociologist and feminist writer."
• C"By narrating her grandmother's subversive storytelling sessions and her mother's quiet acts of resistance within the domestic sphere, Mernissi exposes how supposedly private spaces became sites where women challenged the colonial and patriarchal systems that sought to confine them."
• D"Dreams of Trespass has been celebrated primarily for its lyrical prose style and its contribution to the genre of childhood memoir rather than for its political content."

Which quotation from a forestry research article would most directly support Simard's claim?

• A"Simard's experiments demonstrate that mature trees consistently transfer more carbon to related seedlings than to unrelated ones, suggesting that resource allocation through mycorrhizal networks is selective rather than indiscriminate."
• B"When researchers severed mycorrhizal connections between mature trees and seedlings in experimental plots, seedling survival rates dropped by 40% compared to control plots with intact networks, demonstrating that young trees depend on resource transfers for survival."
• C"Carbon flow through mycorrhizal networks follows concentration gradients, moving from areas of high concentration to low concentration according to basic physical principles, without requiring any coordinated sharing behavior by the trees."
• D"Mycorrhizal fungi benefit from connecting to multiple trees, gaining carbohydrates from mature trees while providing minerals to seedlings, but this arrangement primarily serves the fungus's nutritional needs rather than facilitating cooperation among trees."

Which quotation from Taussig's fieldwork notes most effectively illustrates his claim?

• A"Village churches constructed between 1920 and 1950 feature architectural elements drawn from both Spanish colonial and indigenous traditions, creating hybrid sacred spaces."
• B"Community members explained that by prominently displaying images of Saint Sebastian, who survived arrows, they invoke his protection while secretly addressing prayers to the pre-Columbian deity of the hunt, whom they say 'wears the saint's face to confuse our enemies.'"
• C"Census records show that by 1935, over eighty percent of indigenous households in the region possessed at least one Catholic religious image or object."
• D"Younger community members reported attending Catholic mass regularly and expressed genuine devotion to saints, suggesting successful religious conversion over multiple generations."

Which finding, if true, would most directly support Kohler's claim?

• A"Archaeological evidence from the final decades of occupation shows a marked increase in defensive architectural features and traumatic skeletal injuries consistent with interpersonal violence, even during periods when tree-ring data indicate adequate rainfall for agriculture."
• B"Tree-ring analyses confirm that the Mesa Verde region experienced severe drought conditions lasting several decades around 1300 CE, coinciding precisely with the abandonment of cliff dwellings."
• C"Skeletal remains from multiple Mesa Verde sites dating to the abandonment period show evidence of malnutrition and stress markers, suggesting environmental rather than social pressures."
• D"Excavations reveal that defensive structures and weapons increased dramatically during the abandonment period, while the region remained depopulated for generations despite evidence of improving climate conditions in subsequent decades."

Which quotation from a historical text most directly supports Chen's argument?

• A"Merchants traveling the eastern segments of the trade routes rarely ventured beyond Central Asia, while those in the western segments seldom traveled east of Persia, resulting in goods changing hands multiple times across disconnected regional networks."
• B"The trade routes facilitated not only the exchange of silk and spices but also the transmission of technologies, religions, and artistic traditions across the vast expanse between China and the Mediterranean."
• C"Archaeological evidence reveals that caravanserais were strategically positioned at regular intervals along the routes, suggesting a deliberately planned and maintained infrastructure spanning the entire network."
• D"Trade along these routes fluctuated considerably depending on political conditions, with some periods seeing robust exchange while others experienced significant disruption."

Which quotation from a policy analysis would most effectively illustrate Chetty's claim?

• A"Chetty's findings have influenced urban planning initiatives in several metropolitan areas, where policymakers have sought to implement interventions aimed at improving mobility outcomes for low-income residents."
• B"Children born into the lowest income quintile in San Jose, California, and Charlotte, North Carolina, face vastly different prospects: those in San Jose exhibit mobility rates comparable to Denmark, while those in Charlotte have significantly lower chances of economic advancement."
• C"Analysis of metropolitan areas with similar median household incomes reveals that mobility outcomes diverge sharply based on residential segregation levels and high school graduation rates, with economically integrated communities showing mobility rates three times higher than demographically isolated ones."
• D"Regional economic growth and job availability remain the primary determinants of mobility outcomes, with Chetty's data showing that metropolitan areas experiencing wage growth consistently produce better advancement opportunities for children from all income backgrounds."

Which quotation from a review of Hurston's novel would most directly support Morrison's claim?

• A"The novel's opening pages establish a narrative voice that seamlessly moves between Janie's intimate thoughts and a surrounding community perspective, both rendered in vernacular forms that carry equal weight in shaping the reader's understanding of events."
• B"Hurston's decision to render Janie's interior consciousness in the same vernacular register used for dialogue inverts the conventional hierarchy where standard English narration frames and thus implicitly judges vernacular speech, positioning the vernacular itself as the authoritative lens through which the story is focalized."
• C"Throughout the novel, Hurston demonstrates remarkable skill in capturing the rhythms and idioms of African American vernacular speech, creating dialogue that many critics have praised for its authenticity and vitality."
• D"Some contemporary critics argued that Hurston's vernacular narration limited the novel's accessibility to white readers and thus hindered its potential to advance civil rights causes, a view that later scholars have challenged."

Which quotation from a research paper would most effectively illustrate Rodríguez's claim?

• A"Spectroscopic analysis reveals that outer-region stars contain heavy element abundances matching those found in the galactic core five billion years ago, but show kinematic properties indicating they formed in their current locations."
• B"The heavy element content of outer-region stars suggests that star formation in those areas has been more active than previously believed, challenging existing models of galactic evolution."
• C"Stars in the outer Milky Way exhibit a wide range of elemental compositions, reflecting the complex chemical evolution of our galaxy over billions of years."
• D"Outer-region stars do show elevated heavy element levels, though whether this results from material redistribution or enhanced local enrichment remains debated."

Which quotation from a historian most effectively illustrates Okonkwo's claim?

• A"The Declaration's Article 1 proclaims that 'men are born and remain free and equal in rights,' and this revolutionary assertion inspired subsequent human rights documents including the Universal Declaration of Human Rights adopted in 1948."
• B"The Declaration emerged from Enlightenment philosophy, particularly Rousseau's social contract theory and Montesquieu's writings on separation of powers, reflecting the intellectual currents of 18th-century European political thought."
• C"While the Declaration proclaimed universal rights, the Assembly's subsequent legislation restricted voting to 'active citizens'—property-owning men—and when Olympe de Gouges published her Declaration of the Rights of Woman in 1791 challenging this exclusion, the Assembly refused to debate it, with one deputy arguing that rights language applied only to those capable of rational participation in civic life, a capacity women and non-property holders allegedly lacked."
• D"The Declaration's language about natural rights represented a significant departure from previous political documents that grounded rights in divine authority or monarchical grant, instead locating rights in human nature itself."

Which quotation from a technology policy report would most directly support Mazzucato's claim?

• A"Government laboratories and military research programs developed the core technologies in the iPhone—including the Internet protocols, GPS satellites, touchscreen interfaces, and voice-recognition algorithms—decades before Apple integrated them into a consumer product."
• B"While government funding contributed to early-stage research in computing and communications, private companies invested far more capital in refining these technologies and transforming them into marketable products."
• C"Federal research grants to universities have grown substantially over the past fifty years, supporting scientific investigations across fields from materials science to artificial intelligence."
• D"Government agencies have played an important role in funding basic research, though the most commercially successful innovations typically emerge when this research is combined with entrepreneurial vision and private investment."
