Some of the bronze artifacts excavated at the ancient city of Oakhaven contain trace amounts of zinc. Furthermore, every bronze artifact containing trace amounts of zinc is highly susceptible to rapid oxidation when exposed to humid air. Therefore, some of the bronze artifacts excavated at Oakhaven are highly susceptible to rapid oxidation when exposed to humid air.

Which of the following arguments exhibit a pattern of reasoning logically parallel to that in the argument above? Select all that apply.

City Planner: According to city guidelines, a proposed commercial development can be approved only if it is demonstrated that the project will not compromise the residential character of the surrounding neighborhood. The developers of the proposed Apex Industrial Park have submitted a comprehensive study demonstrating that while their project will significantly increase daytime commercial traffic, it will enforce a strict operating curfew that guarantees nighttime noise levels will remain completely unchanged.

Therefore, the Apex project should be approved.

Which one of the following principles, if valid, most justifies the city planner's reasoning?

Urban Historian: The city's waterfront warehouse district features a distinctive cast-iron architectural style that is no longer utilized in modern construction. Because it employs this obsolete style, the district serves as a tangible link to our region's industrial heritage. Therefore, the city council is obligated to pass legislation protecting the warehouse district from demolition.

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

Legal Scholar: A legal framework is effective only if it continuously adapts to changing societal norms. Furthermore, a framework adapts to changing societal norms if and only if it grants judges broad interpretative discretion. Hence, any effective legal framework must grant judges broad interpretative discretion. Rigid statutory mandates, however, prevent a legal framework from granting judges broad interpretative discretion. Therefore, it is clear that any jurisdiction whose legal framework relies heavily on rigid statutory mandates will ultimately fail to sustain a prosperous economy.

Which one of the following, if assumed, allows the legal scholar's conclusion to be properly drawn?

Business Analyst: To increase productivity, TechCorp recently transitioned to a four-day workweek without reducing employee pay. Studies consistently show that employees who are well-rested make fewer errors and complete their assigned tasks significantly faster. Therefore, TechCorp's overall weekly output will certainly not decrease as a result of this schedule transition.

Which of the following statements must be assumed in order for the analyst's conclusion to be properly drawn? Select all that apply.

Chef: To bake a flawless soufflé, a baker must use room-temperature eggs and precisely fold the egg whites into the batter. Marcus precisely folded the egg whites into his batter. Therefore, if Marcus fails to bake a flawless soufflé, it must be because he did not use room-temperature eggs.

Which one of the following arguments exhibits a flawed pattern of reasoning most similar to that in the chef's argument?

The university's graduate committee has recently updated the financial aid regulations for all incoming and returning students. The new guidelines establish strict conditions for the most prestigious awards. According to the official policy, being awarded the Chancellor's Fellowship requires that a student receive a full tuition waiver and be granted a monthly research stipend.

Which one of the following logically follows from the statements above?

During a recent outbreak of the Z-virus, global health organizations compiled data for Region A and Region B, two regions with exactly the same total population size. The data revealed that the Z-virus mortality rate—defined strictly as the number of deaths per 100 confirmed infected individuals—was twice as high in Region A as it was in Region B. However, the total absolute number of people who died from the Z-virus was significantly lower in Region A than in Region B.

Which of the following statements, if true, provide a complete resolution to the apparent discrepancy described above by explaining both the proportional and the absolute statistics? (Select all that apply.)

For decades, art historians have debated the primary motivation behind the creation of the monumental moai statues of Easter Island. Early theorists argued that the statues were built primarily as territorial markers to intimidate rival clans. Later archaeologists emphasized their role in ancestor worship, suggesting they were erected to capture the mana, or spiritual power, of deceased chiefs. However, recent ecological studies combined with newly translated oral histories point to a different conclusion. The primary purpose of the moai was not militaristic or purely spiritual, but rather agricultural; their construction and strategic placement were intended to stimulate agricultural production by encouraging the fertilization of the island's fragile soil.

Which of the following most accurately states the main point of the passage?

If a startup company secures venture capital funding, it will rapidly expand its operations. The tech startup Zephyr Innovations did not secure venture capital funding. Therefore, Zephyr Innovations will not rapidly expand its operations.

Which of the following arguments exhibits a flawed pattern of reasoning most similar to the one exhibited in the argument above?

Agronomist: The newly developed "Crimson" tomato cultivar has a significantly thicker skin than traditional heirloom varieties. Because of its thicker skin, the Crimson cultivar is far less susceptible to puncturing by standard agricultural harvesting machinery. Therefore, adopting the Crimson cultivar will lead to a more visually appealing crop at the local markets.

The agronomist's argument depends on which one of the following assumptions?

Tech Entrepreneur: Critics argue that our new artificial intelligence program, Zenith, lacks genuine creativity because its output is generated merely by recombining pre-existing data from a vast training set. These critics are fundamentally misguided. It is a well-established psychological fact that human creativity invariably involves the recombination of prior knowledge and experiences; no human being creates in a vacuum. Because human artists are universally acknowledged to possess genuine creativity, it logically follows that Zenith, which also operates by recombining prior inputs, must possess genuine creativity as well.

Which of the following most accurately describes a flaw in the tech entrepreneur's reasoning?

Architectural preservationists often insist that historical buildings must be maintained using exclusively period-accurate materials. This dogmatic approach is ultimately detrimental to the structures it seeks to protect. Preservation boards must become willing to incorporate modern synthetic materials into their restoration projects. These modern materials are significantly more durable than historical counterparts, meaning that buildings restored with them require far less frequent structural intervention over time. Minimizing repeated physical intervention is the single most critical factor in extending a historic building's total lifespan.

Which one of the following most accurately expresses the main conclusion of the argument?

The following dual passages discuss the history and nature of early cinema.

Passage A
The conventional history of film often portrays the medium's first decade as a primitive, transitional era characterized by fumbling steps toward the classical narrative feature film. However, this inherently teleological approach fundamentally misrepresents the true nature and cultural function of early motion pictures. Before roughly 1907, cinema was fundamentally an exhibitionist medium—what scholars have aptly termed a "cinema of attractions." Its primary objective was almost never storytelling; rather, it was the presentation of visual shocks, novelties, and marvels. The camera directly confronted the audience, enthusiastically breaking the so-called "fourth wall" to display technological wonders, acrobatic feats, elaborate stage illusions, or exotic locales. When narratives did exist in these early reels, they were merely thin, disposable pretexts designed specifically to string together these moments of sheer spectacle. The relationship between the spectator and the screen was thus characterized by direct visual astonishment and physiological thrill rather than psychological immersion in a self-contained diegetic world. The subsequent historical shift toward the classical narrative style of the 1910s—with its invisible editing and character-driven plots—was not a natural, inevitable evolution of these early practices. Instead, it was a distinct rupture, a deliberate domestication of a wilder medium intended to court a more respectable, bourgeois audience by aligning film with the established traditions of the theatrical play and the novel. Critics who view early film solely through the lens of modern narrative conventions fail to appreciate the unique, visceral thrills it offered to its original patrons.

Passage B
Recent film scholarship has heavily popularized the concept of the "cinema of attractions," positing a strict, almost unbridgeable dichotomy between early film's emphasis on pure visual spectacle and the sophisticated narrative integration that dominated later eras. Yet, this rigid theoretical division significantly obscures the structural complexities and narrative ambitions of the very earliest motion pictures. Even the briefest, seemingly most spectacular actualities and trick films of the late 1890s possessed inherent, albeit rudimentary, narrative trajectories. The cinematic spectacle was rarely an isolated, plotless phenomenon; rather, it was typically woven into a nascent storytelling fabric from the outset. The famous visual shocks of the era—a locomotive rushing toward the camera, or a magician's sudden, smoke-filled transformation—functioned within a developing, coherent narrative logic that actively guided the viewer's attention from beginning to end. To claim that these early filmmakers were entirely indifferent to story is to ignore the historical evidence of their increasingly complex cinematic choices. Nevertheless, one must acknowledge that the dominant mode of engaging the spectator in these formative years relied overwhelmingly on overt visual stimulation and immediate sensory impact, differentiating it from the deep psychological character development and emotional absorption that would come to define the classical Hollywood era a decade later. Early filmmakers undoubtedly prioritized the immediate thrill of the moving image, even as they experimented with narrative frameworks.

Which one of the following expresses a view held by the authors of both passages?

Match each of the following complex regulatory rules from the International Synchrotron Safety Guidelines to its accurate formal logical diagram.

Let the variables represent the following conditions:
$A$: The accelerator is activated
$B$: The beam is focused
$C$: The cooling system is engaged
$D$: The diagnostic sensors are calibrated

Passage A

For generations, the transition from hunting and gathering to agriculture was depicted by historians as a remarkable triumph of human ingenuity—a so-called "Neolithic Revolution" in which humans deliberately discovered farming techniques and enthusiastically abandoned their ostensibly arduous foraging lifestyles for the security and comfort of settled life. However, modern archaeological and anthropological evidence flatly contradicts this triumphalist narrative. The transition to agriculture was in no way a voluntary step up the ladder of cultural progress, but rather a necessary, and perhaps inevitable, adaptation to relentless demographic pressures. As human populations expanded slowly but steadily during the early Holocene epoch, the natural carrying capacity of local environments for nomadic foragers was gradually stretched to its absolute limits. Faced with dwindling wild resources per capita, these groups were essentially forced to intensify their exploitation of specific plant species, a process that eventually and inadvertently led to full-scale domestication. Far from immediately improving the human condition, the adoption of early agriculture was a desperate measure. Bioarchaeological studies consistently reveal that early agriculturalists actually suffered from substantially narrower diets, more frequent periods of acute starvation, and significantly higher rates of infectious disease compared to their immediate foraging ancestors. Thus, farming was not a brilliant discovery to be universally celebrated, but rather a highly burdensome necessity driven primarily by the inexorable mathematics of population growth.

Passage B

The traditional historical view that agriculture was primarily an intellectual breakthrough—a sudden realization that planted seeds reliably grow into food-producing plants, thereby leading to an immediate and voluntary lifestyle upgrade—is simply no longer tenable in light of modern scientific research. Instead, the origins of agricultural domestication must be fundamentally understood through the complex lens of environmental constraint and climatic instability. During the Younger Dryas, a well-documented period of abrupt global cooling and drying, wild food resources became increasingly scarce and highly unpredictable in pivotal regions such as the Levant. Hunter-gatherer societies, who had previously enjoyed abundant stands of wild cereals in a relatively stable climate, were suddenly forced to cluster tightly around shrinking oases and a few reliable water sources. To merely maintain their baseline food supply in these geographically restricted territories, they had no choice but to begin actively cultivating and managing the wild grasses they had previously only gathered. The long-term consequences of this dramatic shift were biologically profound and largely detrimental. Skeletal remains dating from this specific transition period consistently show clear markers of severe physiological stress, including stunted skeletal growth, pervasive dental caries, and bone lesions indicative of severe nutritional deficiencies and the effects of dense crowding. Agriculture was therefore not a conscious choice for a demonstrably better life, but a reluctant, albeit necessary, coping mechanism deployed in response to profound ecological degradation. This climatic pressure, rather than any intrinsic desire for agrarian life, explains the simultaneous emergence of farming in multiple isolated regions.

Based on the passages, which of the following statements represent a perspective shared by both authors? Select all that apply.

The following dual passages discuss theories regarding the performance of historical musical repertoire.

Passage A
The movement toward historical performance practice (HPP) emerged in the twentieth century as a necessary corrective to the excessive romanticization of earlier music. By that time, Baroque and Classical repertoire had become smothered beneath heavy vibrato, massive orchestral forces, and highly subjective tempos that reflected the modern performer's ego rather than the original composer's design. HPP advocates argue that our primary ethical duty in performance is to the composer. To honor their vision accurately, performers must meticulously consult historical treatises, employ period-appropriate instruments, and strip away centuries of accumulated interpretive habits. It is true, as critics of the movement frequently point out, that standard musical notation from these eras is frustratingly imprecise. A manuscript from the eighteenth century routinely omits crucial details regarding articulation, ornamentation, and phrasing, leaving a considerable amount of information to be deduced. Nevertheless, this inherent ambiguity does not grant modern performers a license to invent or to substitute their own emotional inclinations for historical reality. Rather, it compels them to become musical archaeologists, relying on rigorous academic scholarship to fill the gaps left by the composer's incomplete manuscript. While achieving absolute historical fidelity may ultimately be a distant horizon we can approach but never fully cross, striving for it remains the only objective and defensible standard by which to judge the merit of a performance. Without this anchor, classical music risks devolving into a mere vehicle for contemporary vanity.

Passage B
The growing insistence on strict historical authenticity in musical performance rests upon a fundamental misunderstanding of what the art of music actually entails. A piece of music is not a fragile museum artifact meant to be preserved in a vacuum; it is a dynamic, living dialogue between the past and the present. Those who demand we play Mozart exactly as his contemporaries did willfully ignore the fact that modern audiences possess vastly different auditory expectations, having been shaped by centuries of subsequent musical evolution and acoustic innovation. More importantly, treating the written score as an inviolable sacred text ignores the very nature of musical notation itself. Master composers have always understood that a written score is merely an outline, a pragmatic shorthand that relies entirely upon the interpreting musician to breathe life into it. The composer provides the underlying structural architecture, but the performer must provide the visceral soul. Therefore, an interpreter's primary responsibility is not to subserviently execute a set of antique, skeletal instructions, but rather to translate the emotional core of the historical work for contemporary ears. If a performance fails to resonate emotionally with the modern listener, it has failed entirely in its artistic mission, regardless of how historically accurate the gut strings on the violins or the tuning of the harpsichord might be. The true essence of a composition survives not through sterile replication, but through continuous, imaginative reinvention.

Which one of the following most accurately expresses a principle regarding musical scores that is endorsed by the authors of both passages?

Passage A
The Classic Maya collapse, which occurred over the course of the 9th century CE, is best understood through the lens of environmental determinism and ecological overshoot. In recent decades, paleoclimatological records—specifically data extracted from lake sediment cores and stalagmites in the Yucatán Peninsula—have revealed a series of severe, multi-decadal droughts that precisely track the chronological timeline of urban abandonment. However, climate alone does not fully explain the collapse; rather, the extreme drought acted as the final catalyst that pushed an already deeply strained system over the precipice. By the late Classic period, the Maya had arguably reached the absolute carrying capacity of their fragile tropical environment. Extensive deforestation, conducted to clear land for agriculture and to harvest wood for the massive quantities of quicklime plaster used in their monumental architecture, had not only degraded soil quality but also inadvertently exacerbated local drying trends by reducing evapotranspiration. The tragedy of the Maya was that their brilliant adaptations for managing a challenging rainforest environment ultimately allowed their population to grow so large that they became hyper-dependent on uninterrupted rainfall. When the seasonal rains ultimately failed, the rigid, elite-dominated sociopolitical structure could not effectively pivot. The legitimacy of Maya kings relied heavily on their perceived ability to ensure agricultural fertility through complex rituals. When crops failed repeatedly, rulers lost their divine mandate, leading to a catastrophic breakdown of social order and the depopulation of major urban centers.

Passage B
While it is increasingly popular to point to the weather as the primary culprit for the Classic Maya collapse, attributing the fall of a complex civilization primarily to climate oversimplifies the archaeological record. A closer reading of Maya hieroglyphic texts, alongside physical evidence of rapidly constructed defensive fortifications, suggests that the fatal blow was largely self-inflicted through endemic, escalating warfare. In the centuries preceding the collapse, the fundamental nature of Maya conflict shifted drastically—from highly ritualized skirmishes aimed at capturing high-status hostages, to devastating wars of territorial conquest. This political fragmentation and relentless, violent competition drained crucial resources and manpower. It is demonstrably true that this volatile period coincided with environmental perturbations, and there is little doubt that diminished agricultural yields inflamed existing geopolitical tensions among rival city-states. Moreover, the historically dense populations of the era meant there was virtually no margin for error regarding food security. Yet, the inability to manage these cascading stresses was fundamentally a political failure. This failure was rooted in an inflexible elite class that obstinately prioritized monumental construction and inter-polity warfare over practical infrastructural adaptation, even as their resource base dwindled. Rather than viewing the collapse as a simple story of ecological suicide, we must recognize it as a geopolitical implosion fueled by a competitive arms race for prestige.

Despite their differing primary emphases, the authors share several foundational assumptions about the conditions that led to the Classic Maya collapse. Which assertion from Passage B correctly corresponds to each assertion from Passage A to demonstrate a point of mutual agreement between the two authors?

Passage A
The integration of algorithmic risk assessment tools into criminal sentencing marks a crucial step toward fairer judicial outcomes. For centuries, human judges have operated as legal "black boxes," issuing decisions without providing a truly transparent account of their internal reasoning. A judge's sentencing rationale is inherently subjective, vulnerable to implicit biases, cognitive fatigue, and arbitrary personal heuristics that can lead to wildly disparate sentences for similar crimes. While critics correctly point out that current algorithmic models often reproduce historical biases embedded in their training data, this flaw is a temporary engineering challenge rather than an insurmountable fundamental defect. Unlike the opaque cognitive processes of a human judge, an algorithm's underlying code and data inputs can be mathematically audited, explicitly identified, and eventually corrected by developers. By transitioning to machine-assisted sentencing, the justice system can establish a baseline of quantifiable consistency. Furthermore, algorithms possess the capability to process vast, complex datasets regarding recidivism factors that no human mind could meaningfully synthesize during a trial. As these predictive tools are continually refined, tested, and stripped of their legacy biases, they will inevitably provide a more objective, uniform standard for determining sentences. Doing so will mitigate the capricious nature of purely discretionary human judgment and move the legal system closer to the ideal of blind, impartial justice.

Passage B
The contemporary rush to adopt algorithmic risk assessments in criminal sentencing represents a fundamental misunderstanding of what constitutes justice. Proponents of these systems often argue that computational tools will successfully eliminate the well-documented subjective biases and cognitive opacity that frequently plague human judicial decision-making. Indeed, no serious legal scholar can claim that human judges are perfectly objective; their vulnerabilities to prejudice and inconsistency are a matter of public record. However, replacing the human element with statistical algorithms merely trades the pursuit of individual justice for the cold mechanics of group probability. Algorithmic tools evaluate a defendant not as a unique, autonomous individual, but as a composite of demographic and socioeconomic data points, effectively punishing people based on the statistical behavior of others who happen to share their traits. Moreover, because these machine-learning tools are trained on historically biased arrest and conviction records, they inevitably launder deeply rooted systemic prejudices into a false veneer of mathematical objectivity. Even if these data biases could be perfectly scrubbed by programmers—a highly dubious proposition given the structural realities of the legal system—the core philosophical problem remains unresolved. A human judge, despite their inherent flaws and lack of absolute transparency, uniquely possesses the capacity for moral reasoning. Only a human has the ability to weigh the qualitative, highly specific, and often tragic circumstances of a defendant's life. Algorithms optimize entirely for systemic efficiency and risk management, but true justice requires an individualized moral assessment that no machine can provide.

Both authors would be most likely to agree with which one of the following statements regarding algorithmic risk assessments in criminal sentencing?

Read the following argument carefully. Match each excerpt from the argument (on the left) to the correct description of its structural role in the reasoning (on the right).

Argument:
Despite the assertions of some legal scholars, the recent proliferation of decentralized autonomous organizations (DAOs) does not necessitate a fundamental rewrite of current corporate liability laws. It must be conceded that DAOs lack traditional centralized management, a characteristic those scholars claim renders them immune to statutes requiring an identifiable corporate officer for liability purposes. However, the foundational smart contracts of any DAO establish immutable, predetermined rules for capital allocation, making them functionally analogous to a traditional corporate charter. Because entities governed primarily by rigid corporate charters have historically been successfully regulated under existing legal precedents, the supposedly unprecedented management structure of DAOs actually presents only a superficial jurisdictional challenge.
