Paleontologist Dr. Helena Rostova posits that the initial evolutionary driver of avian flight feathers was strictly thermoregulatory. Rostova argues that the filamentous structures on non-avian theropods served primarily to retain metabolic heat in high-latitude environments, and that their subsequent modification into asymmetric, aerodynamic shapes occurred only after these lineages occupied ecological niches requiring gliding. According to Rostova, any aerodynamic utility in early, symmetrical proto-feathers was purely incidental and insufficient to drive selection, as the physical force generated by such structures during cursorial movement would have been negligible for propulsion.

Text 2

Conversely, evolutionary biologist Dr. Julian Thorne contends that proto-feathers on theropod forelimbs were selected for their aerodynamic utility during cursorial (ground-running) locomotion long before gliding behavior emerged. Thorne points to biomechanical simulations indicating that even symmetric, proto-feathered forelimbs would have generated significant aerodynamic drag and lift during high-speed running, aiding in stabilization, braking, and steep-slope ascent. Consequently, Thorne asserts that thermoregulation was a secondary, co-opted benefit rather than the primary evolutionary catalyst, suggesting that the physiological demands of locomotion shaped proto-feather development from the outset.

Based on the texts, how would Dr. Julian Thorne (Text 2) most likely characterize the claim in Text 1 that symmetrical proto-feathers provided negligible aerodynamic utility during cursorial movement?

Many desert reptiles are active primarily during the early morning and late evening, when air temperatures are moderate. During the hottest hours of the day, these reptiles retreat into deep underground burrows, where temperatures remain significantly cooler than at the surface. Because these species cannot internally regulate their body temperature, they rely entirely on external environments to avoid overheating. If surface temperatures remain excessively high for an extended portion of the day, the reptiles must remain in their burrows to survive. Which choice most logically completes the text?

Text 1
Paleontologist Dr. Sarah Chen argues that the sudden disappearance of the Ediacaran biota—soft-bodied organisms that thrived prior to the Cambrian explosion—was primarily driven by "biotic replacement." Chen posits that the emergence of complex Cambrian animals with novel behaviors, such as active burrowing and predation, disrupted the stable Ediacaran mat-dominated ecosystems, rendering their survival impossible. According to Chen, the extinction was a direct consequence of ecological exclusion by more competitive, evolutionarily advanced species.

Text 2
Geochemist Dr. Marcus Vance maintains that the Ediacaran extinction is best explained by global environmental disruptions rather than biological competition. Vance points to a sharp negative carbon isotope excursion recorded in the geological strata of the late Ediacaran period, which indicates widespread marine anoxia (a severe depletion of oxygen in the oceans). Vance contends that these hostile ocean conditions decimated the Ediacaran organisms, which lacked the respiratory adaptations to survive in low-oxygen environments, thereby clearing the ecological stage for the Cambrian organisms that arose later.

Based on the texts, how would Vance (Text 2) most likely characterize Chen's claim (Text 1) regarding the role of Cambrian animals in the disappearance of the Ediacaran biota?

Many forest tree species form symbiotic relationships with mycorrhizal fungi, which supply the trees with nutrients and water in exchange for carbon. Ecologist Dr. Elena Ruiz hypothesized that during prolonged drought periods, this relationship shifts: rather than maintaining mutual benefit, certain mycorrhizal species become parasitic, consuming carbon from host trees without providing a corresponding increase in water uptake. To test this hypothesis, Ruiz monitored carbon allocation and water uptake in Douglas fir (*Pseudotsuga menziesii*) saplings inoculated with either fungus species A or fungus species B under simulated drought conditions.

Which finding, if true, would most directly support Ruiz's hypothesis?

Text 1
Archaeologist Elena Rossi argues that Roman dodecahedrons—twelve-sided bronze objects found across northern Europe—were highly specialized astronomical instruments used to determine the optimal planting dates for winter grain. Rossi points out that the varying sizes of the circular openings on the faces align precisely with the angles of sunlight during specific agricultural milestones in the northern latitudes. Because these objects are predominantly found in agricultural border provinces rather than urban centers, she concludes they served a practical, localized agrarian function.

Text 2
Historian Marcus Vance maintains that the regional distribution of Roman dodecahedrons is misleading when interpreting their primary utility. Vance notes that the high concentration of these objects in military camps along the Germanic frontier suggests a connection to soldier subcultures or local trade dynamics rather than farming cycles. He argues that if the dodecahedrons were essential agricultural tools, their presence would be documented in contemporary Roman farming manuals, which detail northern agricultural practices yet make no mention of such devices.

Based on the passages, how would Vance (Text 2) most likely characterize the geographical evidence cited by Rossi (Text 1)?

Text 1
Historians studying medieval agriculture often emphasize the role of the heavy plow. Dr. Elena Vance argues that the introduction of the heavy plow in northern Europe during the tenth century was the single most critical driver of population growth, as it allowed farmers to cultivate rich clay soils that were previously unworkable. According to Vance, this technological shift directly stimulated trade and led to the rise of new urban centers.

Text 2
Dr. Marcus Thorne agrees that the heavy plow significantly improved crop yields in northern Europe. However, he cautions that Vance oversimplifies medieval demographics. Thorne points out that regional population increases occurred even in areas where heavy plows were not adopted, suggesting that milder climate trends and the expansion of three-field crop rotation systems played equally vital roles in food security.

Text 1
Many archaeologists have long maintained that the ancient Maya engagement with their surrounding tropical rainforests was purely extractive and ultimately destructive, leading to widespread deforestation that contributed to the civilization's collapse. Proponents of this view point to sediment cores from the Late Classic period showing high rates of forest clearing and subsequent soil erosion.

Text 2
However, paleoecologist Elena Gomez and her team argue that this model overlooks evidence of intentional, long-term forest management. Analyzing macrobotanical remains from ancient Maya forest gardens, they identified high concentrations of economically useful tree species alongside evidence of controlled, low-intensity understory burning. Gomez contends that rather than merely destroying the forest, the Maya actively cultivated resilient, food-producing agroforestry systems.

Based on the passages, how would Gomez and her team (Text 2) most likely respond to the researchers' conclusion in Text 1?

The passage below is adapted from an art history text. Complete the passage by entering the punctuation mark that correctly joins the clauses.

Many botanists initially believed that the *Mimosa pudica* plant���s rapid leaf-folding behavior was a passive reaction to physical touch. However, subsequent studies have revealed that this response is a highly coordinated defense mechanism that requires significant metabolic energy. Thus, what appears to be a simple reflex is actually a ______ physiological process.

For decades, historians assumed that the ancient city of Great Zimbabwe was built solely as a defensive fortress. However, recent archaeological excavations of residential areas and trade goods suggest that the site’s primary function was economic and social, thereby ________ the traditional view that its design was motivated exclusively by military concerns.

Text 1
Traditional models of socio-cultural evolution assert that agricultural surpluses are a prerequisite for the organization of labor required to construct monumental architecture. However, archaeologist Dr. Aris Thorne argues that the temple complex at Göbekli Tepe, built by hunter-gatherers before the rise of farming, reverses this trajectory. Thorne proposes that the shared ritual activity of constructing massive stone pillars served as the primary catalyst for social cohesion, which subsequently drove the transition to agriculture to feed the congregating builders. Thus, monumental architecture was the cause, rather than the effect, of sedentism and agriculture.

Text 2
While acknowledging the impressive scale of Göbekli Tepe, sociologist Dr. Clara Vance contends that attributing its construction entirely to mobile hunter-gatherers overlooks the logistical realities of such an undertaking. Vance argues that a sustained workforce, even if motivated by shared ritual, requires a predictable food supply that transient hunting and gathering cannot reliably provide. She suggests that proto-agricultural practices—such as the intensive harvesting of wild grains, which did not yet constitute full-scale farming but created localized resource abundance—must have already been established in the region to support the builders during construction.

Based on the texts, how would Vance (Text 2) most likely characterize Thorne's claim in Text 1 regarding the relationship between the construction of Göbekli Tepe and the transition to agriculture?

The Venus flytrap (*Dionaea muscipula*) is a carnivorous plant native to subtropical wetlands on the East Coast of the United States. It captures its prey—chiefly insects and arachnids—using a specialized trapping structure formed by the terminal portion of each of the plant's leaves. Once the prey triggers the sensitive hairs on the inner surface of the lobes, the trap snaps shut in less than a second. This rapid movement allows the plant to survive in nutrient-poor soils where other plants struggle to grow.

Which choice best describes the function of the underlined sentence in the text as a whole?

The hydraulis, a precursor to the modern pipe organ invented by Ctesibius of Alexandria in the third century BCE, relied on a unique water-based system to regulate wind pressure. While earlier wind instruments depended entirely on the variable lung capacity of the performer, the hydraulis utilized a reservoir of water situated beneath a metal chamber. Air pumped into this chamber displaced the water, which in turn exerted a steady, upward hydrostatic pressure on the air. This pressurized air was then directed into the pipes when the keys were depressed. Although later Roman engineers replaced the water reservoir with weighted bellows to simplify the instrument’s transport, the original Greek design was highly praised by contemporaries specifically for its ability to maintain a remarkably consistent tone during extended performances.

According to the text, which statement is true about the original Greek hydraulis?

Text 1
Marine biologist Dr. Clara Thorne argues that the rise in anthropogenic ocean noise, particularly from commercial shipping vessels, poses a severe threat to baleen whale populations. Because these ships produce low-frequency sounds that overlap directly with the communication bands of whales, the animals' capacity to navigate, locate prey, and coordinate social behaviors is drastically impaired. Thorne insists that the only viable solution to protect these marine mammals is to implement strict restrictions on shipping lanes, forcing vessels to bypass critical whale habitats entirely.

Text 2
Economist Dr. Aris Mendoza maintains that while commercial shipping noise does intersect with the acoustic range of baleen whales, calls for route restrictions are premature. Mendoza points to recent bioacoustic studies showing that many whale populations exhibit significant behavioral plasticity, successfully modifying the pitch, volume, and timing of their calls to be heard over background noise. According to Mendoza, these adaptive responses suggest that whales can cope with current noise levels, making costly shipping diversions unnecessary.

Based on the texts, how would Mendoza (Text 2) most likely respond to Thorne's proposal to restrict shipping lanes?

For decades, historians assumed that the transition from foraging to farming in the Fertile Crescent was a sudden, localized event driven entirely by sudden climatic shifts at the end of the Younger Dryas period. However, recent archaeological findings at sites like Göbekli Tepe and Tell Qaramel suggest a more gradual, culturally driven transition. At these locations, hunter-gatherer communities constructed monumental stone structures and established semi-permanent settlements long before the widespread domestication of wild grains. These discoveries indicate that complex social organization and communal ritual activity preceded—and likely facilitated—the development of agriculture, rather than being mere consequences of it.

Which choice best states the main idea of the text?

In mid-twentieth-century urban planning, the dominant paradigm advocated by Robert Moses favored large-scale slum clearance and highway construction, assuming these interventions would revitalize declining cities. However, sociologist Jane Jacobs challenged this approach, arguing that vibrant, dense neighborhoods with mixed-use zoning naturally foster safety and economic stability. Jacobs's bottom-up theory posited that diverse street life encourages informal surveillance, which keeps communities secure. Today, many urban planners have abandoned Moses's top-down strategies in favor of Jacobs's community-centered model, demonstrating a paradigm shift in how city design is understood to affect social cohesion.

Which choice best describes the overall structure of the text?

For decades, Mesoamerican scholars believed that Mayan hieroglyphic writing was purely ideographic—representing abstract concepts rather than specific spoken language. This view, championed by prominent archaeologist J. Eric S. Thompson, led researchers to focus almost exclusively on the calendar glyphs, treating the rest of the script as mystical symbols. However, in the 1950s, Soviet linguist Yuri Knorozov proposed that Mayan writing was actually logographic and phonetic, with glyphs representing syllables. Although initially dismissed by mainstream Western scholars, Knorozov's phonetic approach was eventually vindicated, initiating a rapid decipherment of the glyphs that transformed our understanding of Mayan history from a timeless, peaceful aristocracy to a dynamic chronicle of historical rulers, warfare, and alliances.

Text 1
Archaeologist Denise Schmandt-Besserat posits that the small clay tokens recovered from Near Eastern Neolithic sites starting around 8000 BCE formed a standardized accounting system that directly evolved into cuneiform writing. According to her, the uniform shapes of these tokens across disparate regions demonstrate a centralized, shared cognitive framework for tracking goods, serving as the essential precursor that made formal writing systems possible.

Text 2
Piotr Michalowski argues that the token hypothesis oversimplifies the socio-economic variety of the ancient Near East. He points out that similar token shapes were often used for highly localized, unrelated purposes in different settlements, rather than representing a singular, region-wide accounting network. Thus, Michalowski contends that the emergence of cuneiform was driven by complex, localized administrative needs rather than the linear evolution of a unified token system.

Based on the passages, how would Michalowski (Text 2) most likely respond to Schmandt-Besserat's claim in Text 1 that the uniform shapes of clay tokens across disparate regions demonstrate a centralized, shared cognitive framework?

Marine biologist Dr. Sofia Rossi and her team investigated the resilience of two key Caribbean reef-building coral species, *Acropora cervicornis* and *Porites astreoides*, under elevated sea surface temperatures. Corals rely on calcification to build their calcium carbonate skeletons, a process that is often impaired by thermal stress. Rossi hypothesized that while both species would exhibit reduced calcification rates when exposed to heat stress, the structurally denser *Porites astreoides* would demonstrate greater thermal tolerance, maintaining a significantly higher calcification rate than *Acropora cervicornis* at elevated temperatures.

Mean Calcification Rates of Two Coral Species at Different Temperatures:

Which choice most effectively uses data from the table to support Dr. Rossi's hypothesis?

In the field of architectural conservation, nineteenth-century purists often sought to restore monuments to a single, idealized 'original' state, even if doing so required stripping away valuable subsequent additions. In contrast, modern preservationists argue that a building's identity is defined by all the historical periods it has weathered. Consequently, contemporary conservation guidelines advocate for a more ______ approach—one that actively integrates elements from various historical eras rather than enforcing structural uniformity.
