The widespread presence of the sweet potato (*Ipomoea batatas*), a crop native to the Americas, throughout Polynesia prior to European contact has long presented an anthropological puzzle. For decades, the dominant hypothesis, championed by Thor Heyerdahl, posited that prehistoric South American mariners drifted westward, introducing the tuber to the Pacific islands. However, modern linguistic and genetic analyses suggest a different, albeit equally complex, narrative. While the Polynesian word for sweet potato, *kumara*, bears a striking resemblance to the Quechua word *cumal*, radiocarbon dating of sweet potato remains in the Cook Islands predates the earliest evidence of large-scale Andean maritime navigation by several centuries.

Furthermore, recent genomic sequencing of both ancient and modern sweet potato lineages reveals that the Polynesian cultivars form a distinct genetic clade that diverged from South American ancestors roughly 100,000 years ago—long before human settlement of the Americas. Botanists argue that the sweet potato’s seeds, encapsulated in a hard, impermeable coat, are highly adapted for oceanic dispersal via ocean currents or migratory birds. Yet, this purely botanical explanation fails to account for the linguistic confluence.

To reconcile these findings, some anthropologists propose a bidirectional model. They infer that while the plant itself may have arrived in Polynesia via natural mechanisms millennia ago, subsequent, limited contact between Polynesian navigators—who were indisputably capable of traversing the vast expanse to the South American coast—and indigenous Andean populations likely occurred. During these localized encounters, the Polynesians may have adopted the Andean nomenclature for the plant they already possessed, while perhaps exchanging other cultural artifacts or techniques. This synthesis effectively decouples the biological dispersion of the sweet potato from the linguistic transmission of its name, satisfying both the genetic timeline and the linguistic evidence.

The final paragraph of the passage mentions a "genetic timeline" regarding the sweet potato. Based on the information provided in the passage, this timeline establishes which one of the following?

Analyze the passage below discussing late twentieth-century architectural theory. After reading, match each specific detail cited by the author to the primary rhetorical function it serves within the argument.

In late twentieth-century architectural discourse, a salient theoretical schism emerged between Structuralists, who pursued autonomous formal systems, and Phenomenologists, who advocated for the primacy of embodied experience. Structuralists, drawing heavily upon linguistic analogies, approached architecture as an abstract system of signs fundamentally independent of human perception. For instance, Peter Eisenman’s early residential projects, often pejoratively characterized as 'cardboard architecture,' were generated through rigorous geometric permutations that conspicuously subordinated material resonance and functional logic to syntactic complexity. Conversely, phenomenologists such as Juhani Pallasmaa diagnosed the prevailing architectural orthodoxy with an 'ocularcentric bias'—an entrenched over-reliance on visual composition at the expense of other sensory modalities. Pallasmaa championed an architecture that engages the entire human sensorium, citing Alvar Aalto’s meticulously sculpted leather doorknob at the Villa Mairea as a paradigm of design that prioritizes the haptic over the optic, thereby anchoring the discipline back into the phenomenological reality of the physical body.

In the early nineteenth century, American jurisprudence conceptualized the business corporation strictly through the lens of the "artificial entity" theory. Rooted in English common law, this doctrine held that a corporation was a mere creature of the state, existing only by virtue of a legislative charter. Because the corporation was an artificial construct, its rights were strictly limited to those explicitly granted by its charter. State legislatures wielded broad regulatory power over corporate activities, operating on the premise that what the state creates, it can comprehensively control and, if necessary, dissolve. This conceptual framework aligned perfectly with an agrarian economy where corporate charters were typically reserved for public works projects like turnpikes and canals.

By the late nineteenth century, however, the rapid industrialization of the American economy precipitated a crisis in corporate legal theory. The artificial entity doctrine proved overly restrictive for the massive, interstate railroad monopolies and industrial trusts that required unprecedented capitalization and operational flexibility. In response, courts began to embrace the "aggregate" theory of the corporation, which conceptualized the firm not as a state-created entity, but as a private association of individual shareholders. Under this framework, the corporation derived its rights not from a state charter, but from the pre-existing constitutional rights of the individuals who composed it, thereby affording corporations significant protections against state interference under the Fourteenth Amendment.

Mainstream legal historiography has traditionally characterized this doctrinal shift as a natural, almost inevitable intellectual evolution—a pragmatic judicial adaptation to the complex realities of modern capitalism. According to this view, the aggregate theory triumphed simply because the artificial entity doctrine was intellectually obsolete. However, revisionist legal scholars have compellingly challenged this benign narrative. They argue that the adoption of the aggregate theory was not merely an organic adaptation by impartial jurists, but rather the result of a coordinated, decades-long rhetorical campaign waged by elite corporate attorneys. These advocates intentionally deployed the language of individual constitutional rights to construct a judicial shield around corporate capital, deliberately stripping the state of its traditional regulatory oversight. In this revisionist reading, the doctrinal shift was fundamentally a political project, cloaked in the neutral language of legal theory, designed to elevate corporate power above legislative authority.

This critical reevaluation fundamentally alters our understanding of the subsequent emergence of the "real entity" theory in the early twentieth century. If the aggregate theory was a strategic stepping stone rather than an organic intellectual development, the later consensus that corporations are independent, natural entities possessing rights distinct from their shareholders can be seen not as a stabilization of corporate law, but as the final triumph of a systematic effort to emancipate corporate capital from democratic accountability.

Which of the following best describes the primary function of the third paragraph in relation to the passage as a whole?

Linguists use the term "euphemism treadmill" to describe the cyclical process by which words introduced to replace offensive or stigmatized terms eventually absorb the negative connotations of the underlying concepts they signify. Because society attempts to sanitize discourse through mere vocabulary replacement without altering the negative cultural attitudes toward the referent itself, the newly introduced term inevitably becomes tainted by the persistent underlying stigma. Consequently, speakers are forced to abandon the now-tainted euphemism and coin yet another novel term to restore politeness, rendering the linguistic intervention inherently self-defeating and perpetually cyclical.

Which of the following situations is most logically analogous to the phenomenon of the "euphemism treadmill" as described in the passage?

According to the latest meteorological frameworks, any atmospheric pressure system classified as a "hyper-cyclone" forms exclusively over ocean waters exceeding 28°C. A pressure system cannot form over such warm waters unless it is subject to severe Coriolis deflection. Furthermore, no weather system subject to severe Coriolis deflection maintains a perfectly symmetrical eyewall. Observations show that most hyper-cyclones cause significant coastal erosion upon landfall. Additionally, some pressure systems that maintain a perfectly symmetrical eyewall also cause significant coastal erosion upon landfall.

Which one of the following statements must be logically true based on the meteorological frameworks provided?

Read the following passage regarding the historiography of early musical notation. Then, match each specific detail cited from the text to its primary rhetorical function within the author's argument.

Traditional histories of Western music often characterize the advent of written musical notation in the ninth century as a sudden, liberating departure from the constraints of oral tradition. According to this conventional view, the invention of neumes—symbols placed above text to indicate melody—freed singers from the arduous task of memorization. However, modern musicologists argue that early notation was designed to supplement, rather than supplant, oral transmission. The earliest surviving manuscripts feature adiastematic neumes, which indicated the general contour of a melody but lacked specific pitch information, rendering them practically useless to anyone who had not already learned the chant by ear. Furthermore, the initial impetus for recording these melodies was not primarily artistic, but rather stemmed from the rigid standardization of melodies imposed by the Carolingian empire, which sought liturgical uniformity across its vast territories. The theory that notation immediately replaced memory is further undermined by the persistence of rote memorization in monastic choirs well into the twelfth century. It was not until the later invention of the staff by Guido d'Arezzo, which allowed for the exact specification of pitch, that musical notation became truly prescriptive, shifting the locus of musical authority from the singer's memory to the written page.

For decades, the strong version of the Sapir-Whorf hypothesis—the theory of linguistic determinism—enjoyed considerable influence in linguistic anthropology. This framework posited that the structural categories of a language dictate the cognitive boundaries of its speakers, effectively arguing that one cannot conceptualize what one lacks the vocabulary to name. However, the viability of this rigid determinism was fundamentally challenged by empirical investigations into color perception. In classic studies, researchers examined the Dani people of New Guinea, whose language possesses merely two basic color terms, roughly translating to "dark" and "light." Despite this stark lexical constraint, researchers discovered that Dani speakers could identify, match, and remember focal colors across the spectrum with the same cognitive ease as English speakers who utilize dozens of specific color words. By demonstrating that robust perceptual categories can operate independently of linguistic nomenclature, these findings forced a critical reevaluation of the deterministic model in favor of a weaker linguistic relativity.

Which of the following best describes the primary rhetorical function of the author's note that the Dani language "possesses merely two basic color terms"?

In recent years, the conservation strategy known as "Pleistocene rewilding" has transitioned from the fringes of ecological thought to mainstream academic discourse. Its most vocal proponent, evolutionary biologist Aris Thorne, argues that restoring proxies of extinct Pleistocene megafauna—such as introducing modern elephants, camels, and lions to North America to replace extinct mammoths, camelops, and American cheetahs—is essential for restoring true ecological balance. Thorne asserts that the current North American ecosystem is fundamentally incomplete, suffering from a drastic reduction in large herbivores and top predators that shaped the continent’s flora and fauna for millennia. By reintroducing these functional equivalents, Thorne posits, conservationists can revitalize stalled evolutionary processes, control encroaching invasive species, and restore biodiversity to a baseline predating human intervention.

Thorne’s theoretical framework is undeniably elegant, grounded in a rigorous and imaginative interpretation of evolutionary history. His premise that North American flora still bears the unmistakable evolutionary imprint of megafauna—evident in the formidable thorns of the Osage orange or the large, tough fruit of the honey locust, which were once dispersed by mammoths—is well-supported by current paleobotanical evidence. To read Thorne is to be compellingly reminded of the deep, interconnected history of ecosystems and the profound, landscape-altering impact of apex species. He successfully forces the reader to reconsider what constitutes a "natural" landscape.

However, the leap from elegant evolutionary theory to contemporary ecological management is fraught with complications that Thorne’s proposal largely glosses over. The North American landscape has not remained static since the Pleistocene epoch. Millennia of subsequent climatic shifts, extensive human development, and the introduction of countless exotic species have created a novel, highly complex biosphere. Introducing African or Asian megafauna into this delicately reconfigured environment carries enormous risks of unpredictable, cascading ecological disruptions, potentially endangering the fragile native species currently struggling to survive. Furthermore, Thorne noticeably sidesteps the staggering logistical and socioeconomic hurdles of his plan. The acquisition of vast tracts of land necessary to support herds of elephants or prides of lions, and the inevitable, potentially dangerous conflicts with agricultural interests and sprawling urban populations, are treated as mere implementation details rather than fundamental barriers.

Ultimately, while Thorne provides a compelling lens through which to view the evolutionary legacy of North American ecosystems, his prescriptive solution remains tethered more to a romanticized vision of the prehistoric past than to the sobering realities of present-day conservation. The lasting value of his work lies less in its viability as a practical blueprint for action and more in its capacity to force conservationists to think more expansively about ecological time and the critical functional roles of vanished species.

Based on the passage, which of the following phrases best captures the author's attitude toward Thorne's proposal?

The following passage discusses a theoretical framework in regulatory policy.

In the realm of global technological governance, standard-setting organizations (SSOs) often exhibit a subtle phenomenon known as 'epistemic capture.' Unlike traditional regulatory capture, where industry lobbyists directly influence government agencies through financial pressure or revolving-door employment, epistemic capture occurs when the sheer technical complexity of a field necessitates that regulators rely almost entirely on the expertise of the very corporations they are mandated to regulate. Under these conditions, corporations dominate SSOs not by buying votes, but by inundating working groups with proprietary research, thereby effectively defining the parameters of what is technologically feasible. Consequently, the resulting safety or interoperability standards overwhelmingly favor the incumbents' existing patented technologies. The public interest is marginalized not through explicit corruption, but through an asymmetrical distribution of technical knowledge that allows incumbents to frame alternative regulatory paths as technologically risky or theoretically unsound.

Consider the following analogous scenario:

In the field of environmental policy, a newly formed international commission is tasked with establishing global limits on deep-sea mineral extraction. Lacking independent submersibles and geological monitoring equipment, the commission forms an advisory panel staffed primarily by chief scientists from the three largest deep-sea mining conglomerates. These scientists present exhaustive peer-reviewed models suggesting that extraction techniques utilizing their companies' proprietary 'acoustic-damping' technology are the only methods capable of preserving marine biodiversity. Alternative extraction proposals submitted by independent marine biologists are subsequently dismissed by the panel as lacking sufficient empirical validation at extreme depths. Ultimately, the commission drafts extraction protocols that effectively mandate the use of acoustic-damping systems, solidifying the market dominance of the three conglomerates under the guise of environmental stewardship.

Based on the theoretical framework established in the passage, match the abstract conceptual elements of epistemic capture (Left) to their specific functional analogues in the deep-sea mining scenario (Right).

Passage:
During the Gilded Age and the ensuing Progressive Era, classical legal formalism dominated American jurisprudence, serving as the foundational philosophy for both legal education and judicial practice. Formalists viewed the law as a conceptually autonomous system of axioms, rules, and logical deductions, completely independent of the fluctuating social, political, or economic contexts in which it operated. Under this rigorous framework, a contract was perceived simply as a manifestation of mutual assent—a meeting of the minds that created binding obligations. Judges were tasked solely with applying objective, neutral principles to enforce the explicit terms of an agreement. Crucially, this meant that the relative bargaining power, economic desperation, or resource disparities of the contracting parties were considered legally irrelevant. The formalist judge functioned theoretically as a neutral arbiter, merely deducing the correct legal outcome from a closed system of self-contained precedents.

However, the emergence of the Legal Realism movement in the 1920s and 1930s fundamentally challenged this deeply entrenched paradigm. Realist scholars argued that the formalist portrayal of law as a politically neutral, deductive science was a dangerous illusion—one that served to mask the ways in which judicial decisions inherently favored entrenched economic interests. By strictly enforcing contracts between parties with vastly unequal power—such as a monolithic railroad corporation and an individual laborer—under the guise of 'freedom of contract,' the courts were not merely applying neutral rules in a vacuum. Instead, Realists contended, courts were actively intervening in the economy to uphold and legitimize existing market disparities.

According to the Realists, the very act of ignoring social context was a substantive policy choice. When a court refused to consider that a worker might have accepted draconian contractual terms merely to avoid starvation, the court was implicitly endorsing the economic coercion that compelled the agreement. Realists maintained that judges should abandon the pretense of mechanical jurisprudence and instead explicitly consider the social realities and power dynamics shaping any agreement. Consequently, for the Realists, law could not be evaluated in isolation from its practical consequences on human welfare; the true nature of law was to be found in its effects on society rather than in the internal logical consistency of its doctrines.

Statement to evaluate:
Based on the passage, the Legal Realists' critique of classical legal formalism strictly depends on the underlying assumption that formalist judges intentionally sought to oppress individual laborers in order to benefit large corporations.

Read the following passage.

In the mid-twentieth century, the advent of radiocarbon dating revolutionized archaeology by providing a method to determine the absolute age of organic materials. However, early radiocarbon dates often contained systematic errors because the initial method assumed that the concentration of carbon-14 in the atmosphere had remained constant over time. This assumption was later proven false. The breakthrough in correcting these errors came through the application of dendrochronology, or tree-ring dating, specifically utilizing the exceptionally long-lived bristlecone pines of the American Southwest.

Because bristlecone pines can live for several millennia, and their dead wood decays extremely slowly in the arid, high-altitude environment, researchers could construct a continuous tree-ring sequence stretching back nearly 10,000 years. Each tree ring represents a single year of growth, and the wood in that ring captures the carbon-14 ratio present in the atmosphere during that specific year. By radiocarbon dating wood samples whose exact age was already known from the tree-ring count, scientists could compare the radiocarbon age to the true calendar age. This comparison revealed that historical atmospheric carbon-14 levels had fluctuated significantly, primarily due to variations in solar activity and the Earth's magnetic field.

Consequently, archaeologists were forced to calibrate their previous radiocarbon dates, often pushing back the dates of significant prehistoric events, such as the construction of megalithic tombs in Western Europe, by many centuries. This calibration effectively severed the previously assumed diffusionist link between the ancient Near East and early European cultures, establishing that European megalithic architecture developed independently.

Based on the passage, match each explicit textual assertion to the specific inference that can be most logically drawn from it.

Read the following excerpt:

'In the mid-twentieth century, the introduction of the standardized shipping container revolutionized global commerce. Prior to its invention, break-bulk shipping—in which loose cargo was individually handled by longshoremen—was so labor-intensive that the transshipment costs often exceeded the ocean voyage itself. The container drastically reduced these transshipment costs. However, its most profound economic impact was not merely making existing trade cheaper, but making entirely new, hyper-fragmented supply chains viable. For instance, before containerization, the prohibitive cost of transporting raw cotton to Asia and shipping finished garments back to Western markets meant that clothing manufacturing remained highly localized. Once containerization eliminated freight costs as a decisive barrier, apparel brands could decouple production from consumption.'

Statement: The author uses the example of the apparel industry (transporting raw cotton to Asia and shipping finished garments back) primarily to illustrate how the labor-intensive nature of break-bulk shipping made the transshipment process more expensive than the ocean voyage itself.

Based on the text concerning common-pool resources, match each claim on the left with its treatment in the passage on the right. Note that three of the claims are explicitly supported by the text, while one claim is NOT supported and serves as a contradicted outlier.

The economic concept of the "tragedy of the commons," popularized in the late 1960s, suggests that individuals acting in self-interest will inevitably deplete shared resources. The original formulation of this theory insisted that environmental ruin could only be averted through one of two mechanisms: either the total privatization of the resource, or the imposition of coercive state regulation. This pessimistic view dominated public policy for decades, influencing international approaches to forestry and fisheries.

Decades later, political economist Elinor Ostrom dismantled this binary assumption through empirical field research. By studying irrigation systems in Nepal and forests in Switzerland, Ostrom proved that local communities frequently govern shared resources effectively without state intervention or private property rights. She observed that sustainable communal management typically depends on clearly defined geographic and social boundaries, which prevent external actors from exploiting the local commons.

Additionally, Ostrom identified several structural prerequisites for enduring communal institutions. Chief among these are collective-choice arenas, which ensure that the individuals most affected by resource rules maintain the authority to modify them over time. Effective systems also require localized monitoring; individuals auditing resource conditions must be accountable directly to the community rather than to a distant bureaucracy. Finally, infractions must be met with graduated sanctions—initial minor violations receive mere warnings, while repeated abuses trigger increasingly severe penalties.

In the study of early agrarian societies, traditional historians have long maintained that the transition from foraging to agriculture was primarily driven by climate change, which forced nomadic populations to settle near stable water sources. This "environmental determinism" view has recently been challenged by social archaeologists, who argue that the shift to agriculture was instead a byproduct of social competition and the desire of emerging elites to accumulate surplus wealth.

While social factors certainly played a major role in the subsequent expansion of established agricultural communities, the initial domestication of crops coincides too perfectly with the end of a major global cold period to dismiss environmental triggers. Thus, while the social archaeologists have usefully highlighted the political dynamics of early farming villages, their outright dismissal of climate as the primary initial catalyst is premature.

Which one of the following most accurately describes the author's stance toward the viewpoint of the social archaeologists?

City Planner: Every municipality that successfully transitions to a zero-emissions public transit fleet within five years must upgrade its local electrical substations to handle high-capacity charging. City Council recently approved a comprehensive modernization plan that will fully upgrade all municipal substations within the next two years. Therefore, provided the substation upgrades are completed on schedule, the city is certain to successfully transition to a zero-emissions public transit fleet within five years.

Which one of the following most accurately describes the flaw in the city planner's reasoning?

While standard legal histories often characterize the 1710 Statute of Anne as a sudden, principled triumph of authors' natural rights over the monopolistic control of the Stationers' Company, recent scholarship suggests a more pragmatic evolution. The Stationers' Company, which had lost its lucrative licensing monopoly in 1695, aggressively lobbied for the new statute not out of a sudden respect for authorial genius, but as a mechanism to regain regulatory control over the increasingly chaotic book trade. The statute's subsequent inclusion of the author as the initial copyright holder—a feature often heralded as a philosophical shift toward John Locke's labor theory of property—was primarily a politically palatable compromise. It allowed publishers to continue dominating the trade by merely requiring them to purchase these newly created authorial rights, thereby securing legally enforceable exclusivity without appearing to revive an unpopular monopoly.

Based on the passage, which of the following accurately describe the rhetorical function of the author's reference to the fact that the Stationers' Company 'had lost its lucrative licensing monopoly in 1695'? Select all that are correct.

In examining the trajectory of twentieth-century urban planning, one must navigate a landscape littered with utopian blueprints, many of which faltered upon encountering the friction of lived reality. Ebenezer Howard’s Garden City movement, emerging at the dawn of the century, sought to marry the economic vitality of the metropolis with the hygienic virtues of the countryside. Howard’s vision was fundamentally communitarian, aiming to emancipate the working classes from the squalor of industrial slums by creating self-contained communities surrounded by greenbelts. While one must acknowledge the inherent nobility of this socioeconomic aspiration, the physical realization of his models too often devolved into insular, low-density suburbs that merely reinforced the class stratification he originally sought to dismantle. His paradigm, though undeniably well-intentioned, ultimately lacked the robust flexibility required by dynamic, rapidly expanding urban populations.

Conversely, the High Modernist ethos championed by Le Corbusier in his *Ville Radieuse* sought to impose a radically different order upon the urban fabric. Driven by an obsession with hyper-rationalization, efficiency, and automobile-centric infrastructure, the High Modernists envisioned cities as "machines for living." Their proposed absolute segregation of functions—dividing the city into discrete, non-overlapping zones strictly designated for dwelling, working, and recreation—betrayed a profound hostility toward the organic complexity of traditional urban life. This architectural megalomania, characterized by towering concrete monoliths set amidst desolate, windswept plazas, effectively sought to engineer human behavior through rigid spatial dictation. The outcome was the creation of sterile environments that systematically extinguished civic vitality and alienated residents.

A necessary corrective to such top-down hubris emerged in the grassroots urbanism popularized by later theorists, most notably Jane Jacobs. By championing the "intricate sidewalk ballet" of dense, mixed-use neighborhoods, this perspective eschewed grand, abstract architectural theories in favor of granular, empirical observation of how citizens actually interact with their built environment on a daily basis. This paradigm rightly recognizes that a city's resilience is intrinsically linked to its diversity and emergent order, rather than to any imposed geometric symmetry. The triumph of this observational approach lies in its profound respect for the agency of the individual urban dweller. Ultimately, the history of twentieth-century urbanism suggests a clear lesson: successful cities cannot be unilaterally sculpted from above; rather, they must be allowed to organically cultivate themselves from the pavement up.

Based on the passage above, match each urban planning concept or outcome to the phrase that best describes the author's attitude toward it.

Historically, environmental regulation in many jurisdictions operated predominantly on a precautionary principle: if a novel chemical compound's physiological or ecological effects were unknown, its industrial application was generally restricted until developers could affirmatively prove its safety. However, the late twentieth century witnessed a profound regulatory paradigm shift with the widespread adoption of probabilistic risk assessment (PRA). PRA mandates that regulatory intervention be predicated upon quantifying the exact likelihood of specific harms, fundamentally shifting the epistemological focus of environmental law from hazard identification to risk management.

Proponents of this methodological shift argue that PRA rationalizes the regulatory landscape. They contend that, rather than relying on absolute prohibitions that invariably stifle industrial innovation and economic growth, PRA provides an ostensibly objective mathematical framework. By quantifying danger, it allows regulatory bodies to weigh the projected economic benefits of a substance against a calculated threshold of acceptable risk. Consequently, proponents maintain that PRA optimizes public welfare by directing finite oversight resources toward statistically significant threats rather than merely theoretical ones.

Despite these claims to administrative efficiency, the PRA paradigm is structurally problematic. By demanding that risk be mathematically quantified before protective action is initiated, PRA systematically advantages industrial stakeholders. In the case of emerging chemical contaminants, epidemiological and ecological data are frequently sparse or entirely absent. In such instances, calculating a precise probability of harm is a mathematical impossibility. Yet, within the rigid architecture of the PRA framework, this absence of quantifiable risk is functionally translated into a zero-risk scenario. Regulatory inaction is thereby justified not by empirical evidence demonstrating a chemical's safety, but by a methodological inability to measure its potential danger.

Therefore, the adoption of PRA fundamentally reconfigures the burden of proof in environmental regulation. By tethering regulatory intervention to a mathematical threshold that cannot be met without extensive longitudinal data, the framework inadvertently transforms scientific uncertainty from a justification for caution into an impermeable shield for potential polluters. In doing so, PRA routinely exposes populations to unquantifiable hazards under the guise of scientific and statistical rigor.

The author’s conclusion that the PRA framework systematically advantages industrial stakeholders by justifying regulatory inaction depends on which one of the following assumptions?

The Julian calendar, introduced by Julius Caesar in 45 BCE, represented a significant advancement in timekeeping by establishing a 365-day year with an additional day added to every fourth year. This system assumed a solar year of exactly 365.25 days. However, the actual solar year—the time it takes for the Earth to complete one revolution around the Sun—is approximately 365.2422 days. Although this annual difference of 11 minutes and 14 seconds seems minuscule, over the centuries, the Julian calendar's slight overestimation of the year's length caused its dates to drift out of alignment with the astronomical seasons. By the late sixteenth century, the vernal equinox, traditionally observed on March 21, was occurring around March 11 on the calendar. This drift presented a serious problem for the Catholic Church, as the calculation of the date of Easter was strictly tied to the vernal equinox. To rectify this discrepancy, Pope Gregory XIII introduced the Gregorian calendar in 1582. The Gregorian reform advanced the calendar by ten days to restore the equinox to March 21. Furthermore, it refined the existing leap year rule to prevent future drift: under the new system, century years would be counted as leap years only if they were divisible by 400. This modification reduced the average year length to 365.2425 days, bringing it much closer to the true solar year.

Based on the passage, which of the following can be inferred about century years under the Julian calendar?

Biologists have long debated the primary function of the zebra's stripes. Early researchers confidently asserted that the pattern served as camouflage against predators in the tall savanna grass. Modern field studies, however, present a compelling case for a different mechanism. The data strongly indicate that the striking black-and-white pattern functions primarily to deter biting flies, which are known to avoid landing on striped surfaces. While other secondary benefits cannot be entirely ruled out, the fly-deterrence hypothesis currently offers the most robust explanation for this evolutionary adaptation.

Which one of the following most accurately describes the author's degree of commitment to the fly-deterrence hypothesis?
