In an effort to reduce urban noise pollution, the city of Oakhaven replaced all of its traditional diesel buses with electric buses. Electric buses produce significantly less engine noise than diesel buses. However, electric buses are heavier and cause more tire-to-road friction noise at speeds above 40 km/h than diesel buses do. Most of the bus routes in Oakhaven's residential neighborhoods have speed limits of 30 km/h and are designed with frequent stops, preventing buses from exceeding these limits. Conversely, the bus routes connecting Oakhaven's commercial districts to the suburbs often require buses to travel at speeds up to 60 km/h for extended stretches.

Which one of the following is most strongly supported by the information above?

Urban planner: Establishing a comprehensive toll zone in the city center is a guaranteed method for achieving a substantial drop in the number of commuter vehicles. However, the city council recently voted to permanently reject the mayor's toll zone proposal. Therefore, it is certain that there will be no substantial drop in the number of commuter vehicles this year.

The urban planner's argument is most vulnerable to criticism on the grounds that it

In ancient Mediterranean societies, the widespread adoption of standardized silver coinage often occurred concurrently with an increase in long-distance maritime trade. However, historians note that the earliest standardized coins were minted almost exclusively in small denominations, which were highly impractical for large-scale maritime transactions but well-suited for daily wage labor and local retail markets. Furthermore, long-distance trade had flourished for centuries prior to the introduction of coinage, relying on weighed bullion and credit systems.

Which of the following statements is most strongly supported by the information above?

In the city of Oakhaven, the municipal recycling facility processes only plastics labeled type 1 and type 2. If a collected batch of recyclable materials contains any other types of plastic, the facility must either employ manual sorters to remove the unaccepted items or send the entire batch to the landfill. Due to severe municipal budget cuts this year, the facility currently has no manual sorters and has no means to acquire them. Nevertheless, recent audits indicate that more than half of the recycling batches collected from Oakhaven's residential bins contain plastics other than types 1 and 2.

Which one of the following statements is most strongly supported by the information above?

University Dean: We are faced with a stark choice. We must either completely abolish our classical liberal arts curriculum in favor of purely vocational training, or we must accept that our graduates will be entirely unemployable in the modern economy. Because it is unacceptable for our graduates to be unemployable, we have no choice but to immediately transition to a purely vocational curriculum.

Which one of the following most accurately describes a flaw in the dean's reasoning?

Philosopher: For a scientific theory to be universally accepted, it must not only withstand rigorous empirical testing but also align with the prevailing metaphysical assumptions of the era. The new theory of quantum gravity has successfully withstood the most rigorous empirical testing currently available. Therefore, provided that this new theory is shown to align with the prevailing metaphysical assumptions of our era, it will inevitably gain universal acceptance within the scientific community.

Which of the following most accurately describes a logical flaw in the philosopher's reasoning?

Linguists studying the Voro language family have observed that Voro languages that evolved in coastal environments possess a highly specialized vocabulary for distinct types of ocean currents. In contrast, Voro languages that evolved in inland, arid regions almost entirely lack such vocabulary. The modern language of Zani, which belongs to the Voro family and is spoken exclusively by a nomadic population in a landlocked desert, nonetheless contains an extensive array of archaic terms for ocean currents. Historical texts provide strong evidence that the Zani people have never traded or interacted with coastal populations.

Which one of the following is most strongly supported by the information above?

In classical jurisprudence, 'desuetude' refers to the doctrine whereby a statute or legal regulation lapses and becomes unenforceable due to a long history of non-enforcement by authorities. However, relying strictly on this institutional metric fails to capture the sociomoral dynamics at play in rapidly evolving societies. We must instead recognize the phenomenon of *normative desuetude*—a condition that arises not merely when agents of the state cease to prosecute a transgression, but when the transgression itself is systematically absorbed into the baseline of acceptable public conduct by the citizenry, thereby dissolving the underlying moral warrant for the law's existence, regardless of the state's enforcement posture.

Based on the passage, the author uses the phrase "normative desuetude" to refer to which of the following?

In analyzing the ratification of the United States Constitution, contemporary legal historians often rehearse the well-documented ideological clashes between the Federalists and Anti-Federalists regarding the centralization of federal power. However, by continually re-litigating these prominent theoretical disputes, such scholarship risks marginalizing the equally contentious, yet more pragmatic negotiations over interstate commerce and taxation that fundamentally dictated the document's operational mechanics.

Which one of the following most accurately expresses the meaning of the word "rehearse" as it is used in the passage?

Contemporary critiques of canonical sociological frameworks frequently emphasize the provincial nature of their foundational assumptions regarding human motivation. By anchoring their analytical models almost exclusively in the socioeconomic rhythms of industrializing Western European metropolises, these pioneering theorists inadvertently calcified paradigms that prove acutely inadequate when tasked with accommodating the relational fluidities indigenous to non-Western or agrarian societies.

Which of the following best captures the meaning of the word "provincial" as it is used in the passage?

A commercial air carrier recently terminated its contract with a software vendor that developed its automated flight-rescheduling algorithm. The airline took this action after discovering that, although the algorithm reduced total passenger delays across the network more effectively than human dispatchers, it achieved these efficiencies by disproportionately canceling flights on low-demand regional routes where passengers have no alternative transportation. The airline's executives maintained that passengers in isolated regions should not bear a disproportionate burden merely to optimize system-wide travel times. Which of the following principles, if valid, most helps to justify the airline executives' decision?

Ecologist: Every songbird species capable of vocal mimicry possesses a specialized syringeal muscle structure. However, certain avian species indigenous to the cloud forest lack this specialized syringeal muscle structure. Therefore, some avian species indigenous to the cloud forest are not songbird species capable of vocal mimicry.

Which of the following arguments is most similar in its logical reasoning to the argument above?

Agronomist: For decades, the persistently low crop yields in the Xanthus Valley were universally attributed to the high concentration of free aluminum ions in the soil, which are highly toxic to most commercial crops. To resolve this, farmers recently treated the valley's soil with a novel synthetic chelating agent that permanently neutralizes all free aluminum ions, rendering them completely biologically inert. However, subsequent harvests in the treated fields have shown no increase in crop yields. Therefore, it is evident that the high concentration of free aluminum ions was not the primary factor limiting crop yields in the valley.

Which one of the following is an assumption on which the agronomist's argument depends?

Passage A
Historically, anthropologists defined hominins largely by their unique ability to conceptualize, manufacture, and systematically use tools. This capability established a theoretical cognitive Rubicon that supposedly separated human ancestors from all other primates, reinforcing a narrative of human exceptionalism. However, decades of rigorous field research on wild chimpanzees have steadily dismantled this paradigm. Observations in natural habitats reveal that chimpanzees not only use found objects—such as employing carefully selected sticks to extract termites from mounds—but they also actively modify raw materials to suit specific functional tasks, demonstrating a clear mental representation of a desired outcome before action is taken. More significantly, the documented variations in tool-use behaviors across different, isolated chimpanzee populations strongly point to cultural transmission. For instance, a community residing in the Taï Forest may exclusively employ heavy stone hammers to crack hard-shelled nuts, whereas a group in Gombe relies entirely on wooden implements for the exact same purpose, despite the robust availability of similar natural resources in both ecological zones. These regional differences cannot be explained as genetically hardwired instincts; rather, they are complex, learned behaviors passed down through generations via prolonged social observation and imitation. Consequently, the study of chimpanzee tool use forces the scientific community to recognize that advanced cognitive abilities and the mechanisms of cultural inheritance are not strictly human traits, but are deeply rooted in our shared evolutionary history.

Passage B
For the better part of a century, cognitive science operated under the firm assumption that the avian brain, lacking the enlarged and highly folded neocortex characteristic of higher mammals, was fundamentally incapable of advanced problem-solving or abstract thought. This restrictive perspective has been radically revised in light of contemporary research on corvids, particularly focusing on the New Caledonian crow. In both controlled experimental settings and highly competitive natural environments, these birds exhibit an astonishing aptitude for targeted tool creation. They do not merely use objects; they routinely bend stiff twigs into precise hooks or fashion complex, stepped cut-outs from pandanus leaves to securely extract grubs from narrow, inaccessible crevices. What elevates this remarkable behavior from mere genetic instinct to evidence of advanced cognition is the cumulative nature of their technological refinement. Young crows spend extensive periods closely observing adult toolmakers, gradually acquiring the intricate motor skills and structural understanding required to manufacture these specific implements. Furthermore, field researchers have documented highly distinct regional variations in the design of pandanus tools across different geographic territories in New Caledonia, proving that these designs are socially transmitted. The indisputable fact that an avian species can sustain a resilient material culture, complete with regional tool dialects, profoundly challenges the longstanding mammalian bias in comparative cognitive studies. It powerfully demonstrates that the capacity for cultural transmission and sophisticated tool manufacture evolved entirely independently in birds.

Based on the provided texts, which of the following statements accurately express a central argument shared by the authors of both Passage A and Passage B? (Select all that apply)

Passage A
Art historians have long debated the sudden and overwhelming international triumph of Abstract Expressionism in the years following World War II. While the formal innovations of artists like Jackson Pollock and Mark Rothko are undeniably significant, the movement's meteoric rise to global prominence cannot be fully understood outside the context of Cold War politics. In the late 1940s and 1950s, influential American art critics and major cultural institutions, most notably the Museum of Modern Art, began to aggressively champion the movement. They actively framed the chaotic, completely nonrepresentational canvases as the ultimate manifestation of Western individualism, spontaneity, and unbridled creative liberty. The ability of artists to paint without recognizable subject matter was heralded as the absolute antithesis of totalitarian control. This critical framing was deliberately and explicitly positioned in stark contrast to the rigid, state-mandated aesthetic of Soviet Socialist Realism, which demanded strict ideological conformity and realistic depictions of proletarian life. Consequently, the American cultural establishment embraced Abstract Expressionism not merely for its aesthetic breakthroughs, but primarily because it served as a potent, highly visible emblem of the intellectual freedoms purportedly enjoyed under democratic capitalism. The movement's unprecedented dominance in the art world was, therefore, significantly propelled by its strategic alignment with the era's dominant geopolitical imperatives.

Passage B
The conventional narrative of American modern art frequently centers on the lone, rebellious genius striving for pure aesthetic expression, isolated from political concerns. However, the global ascendance of Abstract Expressionism was heavily aided by a remarkably coordinated, albeit covert, state apparatus. Extensive historical research has recently illuminated the surprising extent to which the United States government, particularly through its intelligence agencies, secretly funded, organized, and promoted international exhibitions of abstract art throughout the early Cold War period. This cultural Cold War was viewed by policymakers as being just as critical to national security as the military standoff. Front organizations, such as the Congress for Cultural Freedom, were strategically utilized to bypass conservative domestic political opposition, which frequently derided modern art as subversive or aesthetically nonsensical. By secretly sponsoring lavish European tours featuring the works of American abstract painters, the government sought to directly counteract pervasive Soviet propaganda that routinely depicted the United States as a culturally barren, fiercely materialistic wasteland devoid of intellectual sophistication. The overarching objective of this clandestine program was to demonstrate unequivocally that a free, democratic society could foster dynamic, avant-garde, and intellectually rigorous cultural production. Thus, the international prestige and rapid dissemination of Abstract Expressionism was not a purely organic artistic phenomenon resulting solely from aesthetic evolution. Rather, it functioned as a vital, subsidized component of a deliberate ideological strategy designed to win the cultural allegiance of the European intelligentsia.

Which one of the following most accurately expresses the main point shared by both passages?

Lichenometry is a dating technique based on the predictable, radially symmetrical growth rates of crustose lichen species, such as Rhizocarpon geographicum, colonizing freshly exposed rock surfaces. Because these organisms require direct exposure to sunlight and atmospheric moisture while remaining intolerant of rapid substrate erosion, successful colonization occurs almost exclusively on stable rock faces immediately following glacial retreat or landslide events. However, because lichen growth rates vary inversely with altitude and depend heavily on microclimatic humidity, researchers cannot establish universal growth curves; instead, calibration curves must be constructed independently for each specific geographic microregion using substrates of historically documented ages.

Which of the following can be most reasonably inferred from the passage regarding the application of lichenometry?

An independent investigative news syndicate recently made several contentious editorial determinations regarding pending investigative reports. Match each editorial determination to the general journalistic principle that most directly justifies it:

Analyze the logical structure of the argument provided below.

'Scientific theories are often praised for their predictive power, yet the ability of a theory to yield accurate predictions does not guarantee its fundamental truth. Consider that historically, many theories that produced highly accurate predictions were later found to be based on entirely false ontological premises. Because predictive success can be achieved through models that merely happen to align with observable data by coincidence, empirical adequacy is merely a pragmatic virtue. If empirical adequacy does not entail truth, we must reject the notion that a theory's predictive success provides conclusive evidence that it accurately describes the underlying reality of the universe. Therefore, scientific realism—the belief that our best scientific theories are true descriptions of nature—is fundamentally flawed.'

Arrange the following statements in the exact logical sequence that the author uses to build the argument, starting from the foundational empirical premise and culminating in the ultimate main conclusion.

Please read the following passage carefully.

For centuries, the Ptolemaic model of the universe dominated astronomical thought, relying on a complex system of deferents and epicycles to explain the seemingly erratic retrogradations of planetary motion. However, this system suffered from a significant physical implausibility: the equant. The equant was a mathematical point situated opposite the Earth from the center of the deferent, from which the planet's epicycle appeared to move at a uniform angular velocity. While computationally effective for predicting planetary positions, the equant violated the Aristotelian physical principle that all celestial motion must be uniform and circular around a central point.

In the thirteenth century, astronomers at the Maragha observatory, led by the Persian polymath Nasir al-Din al-Tusi, sought to resolve this contradiction. Their goal was not to overthrow the geocentric paradigm—which remained conceptually unquestioned—but rather to synthesize Aristotelian physics with Ptolemaic mathematical astronomy. To this end, al-Tusi developed a geometric theorem now known as the 'Tusi couple.' This mathematical device consists of a smaller circle rotating inside a larger circle twice its diameter. As the smaller circle rolls inside the larger one, a point on the circumference of the smaller circle oscillates back and forth along a straight line. By replacing the problematic equant with a combination of uniformly rotating circles, the Tusi couple successfully generated linear motion from circular motion.

Al-Tusi incorporated this device into his planetary models, most notably in his lunar model, to preserve uniform circular motion while closely matching the empirical accuracy of Ptolemy's equant-based predictions. Crucially, the Maragha astronomers did not employ the Tusi couple to alter the cosmological structure of the universe. Instead, they utilized it as a strictly kinematic mechanism to purge Ptolemaic models of physical absurdities.

Centuries later, Nicolaus Copernicus utilized an identical mathematical mechanism in his 'De revolutionibus orbium coelestium'. Copernicus employed the Tusi couple to model the oscillation of the planetary spheres and the variation in orbital speeds without relying on an equant. The striking geometric similarity between the Maragha models and those of Copernicus has led many historians of science to posit a direct transmission of Islamic astronomical knowledge to Renaissance Europe. Yet, regardless of the transmission debate, the functional application of the Tusi couple in both systems underscores a shared methodological commitment: the strict adherence to the principle of uniform circular motion, a constraint that both the Maragha astronomers and Copernicus viewed as non-negotiable for any true physical representation of the heavens.

Determine whether the following statement is TRUE or FALSE based exclusively on the explicit information provided in the passage:

Statement: The Tusi couple replaced the Ptolemaic equant by utilizing a large circle that oscillates along a straight line within a smaller, uniformly rotating circle, thereby successfully generating uniform circular motion from linear motion.

Political Theorist: For any grassroots insurgency to achieve systemic political reform, it must maintain ideological orthodoxy while simultaneously cultivating a broad electoral consensus. Cultivating such a consensus universally necessitates that the insurgency's leadership forge alliances with incumbent political factions. Yet, the very act of forging alliances with incumbent political factions inevitably compromises the foundational tenets of the insurgency's original manifesto. It therefore follows that no grassroots insurgency can achieve systemic political reform.

The conclusion of the political theorist's argument follows logically if which one of the following is assumed?
