Consider the following passage concerning international legal theory.

Traditional accounts of customary international law (CIL) posit a dual requirement for the crystallisation of a binding norm: consistent, widespread state practice combined with opinio juris—the conviction that such practice is legally mandated. Historically, this evolution was notoriously glacial, reliant upon the slow accretion of diplomatic correspondence and state actions. However, the proliferation of United Nations General Assembly (UNGA) resolutions has prompted some contemporary legal scholars to advocate for the concept of "instant custom." These scholars argue that overwhelmingly supported resolutions can bypass the temporal requirement of state practice, effectively serving as legislative acts that bind the international community.

This modern proposition, while attractive in its capacity to rapidly address emerging global crises, fundamentally misapprehends the structural limitations of the UN system. The UN Charter explicitly restricts the General Assembly to a recommendatory role. Therefore, while near-unanimous resolutions can certainly accelerate the articulation of emerging norms, they cannot independently substitute for material state practice. Rather than acting as binding legislation, these resolutions are best understood as highly persuasive, yet subsidiary, evidence of nascent opinio juris. A resolution may reflect what states believe the law ought to be, but absent congruent state behavior, it cannot dictate what the law is.

This distinction was vividly illustrated in the recent Texaco v. Libya arbitration, where the tribunal confronted a UNGA resolution purporting to establish absolute sovereignty over natural resources. Despite the resolution's broad support among developing nations, the sole arbitrator rejected its status as binding CIL, noting that the vigorous objections and contrary practices of capital-exporting states fatally undermined any claim of universal custom. The tribunal correctly recognized that a resolution's text, no matter how emphatic, collapses as a source of law when contradicted by the empirical reality of state conduct.

Analyze the structural components of the author's argument. Pair each of the following textual excerpts with its correct rhetorical function within the passage as a whole.

In recent years, the rapid proliferation of algorithmic pricing models has fundamentally challenged traditional antitrust frameworks. Historically, prosecuting antitrust violations has required evidence of an explicit agreement—a "meeting of the minds"—to fix prices or restrict output. However, modern algorithms can autonomously learn to collude and maintain supracompetitive prices without any explicit human communication or programmatic directives to do so. This phenomenon, often termed "tacit algorithmic collusion," renders conventional definitions of price-fixing legally inadequate and leaves a significant regulatory void.

Legal scholar Aris Thorne, in his latest comprehensive treatise, proposes a novel solution to this modern dilemma: shifting the focus of antitrust scrutiny entirely from the subjective intent of human operators to the predictable structural effects of the algorithmic architecture itself. Thorne argues that if a pricing algorithm is designed and deployed in a way that predictably stabilizes prices across a sector—for example, by utilizing reinforcement learning models that optimize for long-term market stability rather than short-term volume—its deployment should be considered a per se violation of the Sherman Antitrust Act. He contends this should hold true regardless of whether traditional evidence of collusion exists, effectively proposing a regime of strict liability for anti-competitive algorithmic outcomes.

Thorne’s framework is undeniably elegant and offers a much-needed modernization of antitrust jurisprudence. By attempting to bypass the often-insurmountable evidentiary hurdle of proving intent within a black-box algorithmic environment, Thorne provides regulators with a conceptually pragmatic tool to address the stark realities of modern digital markets. His rigorous analysis of how machine learning models can organically arrive at collusive strategies is particularly illuminating, successfully demystifying a highly technical and opaque phenomenon for legal practitioners and judges who often lack computer science backgrounds.

However, when translating this theoretical model into a practical regulatory framework, Thorne’s proposal ultimately stumbles. His core recommendation relies heavily on the underlying assumption that regulatory bodies possess both the advanced technical expertise and the real-time access necessary to audit complex, proprietary algorithms effectively. This optimistic view completely overlooks the entrenched informational asymmetry and resource disparity between multinational tech conglomerates and chronically underfunded regulatory agencies. Furthermore, Thorne’s strict liability approach threatens to chill legitimate, pro-competitive algorithmic innovations, such as dynamic pricing models that efficiently match supply and demand during sudden market fluctuations. While his theoretical diagnosis of the algorithmic collusion problem is exceptionally astute, the blunt regulatory instrument he offers as a cure fails to account for the delicate, precise balance required in governing dynamic digital economies.

Which of the following best describes the author's attitude toward Thorne's proposed regulatory framework?

Read the argument and evaluate the statement that follows.

City Planner: Any city that successfully revitalizes its downtown commercial district must offer extensive public parking. The municipality of Riverbend recently constructed several large public parking facilities in its downtown area. Therefore, Riverbend's downtown commercial district will undoubtedly be successfully revitalized.

Statement: The city planner's argument is vulnerable to criticism on the grounds that it treats a condition that is necessary to bring about a particular outcome as a condition that is sufficient to guarantee that outcome.

Passage A

In the late nineteenth and early twentieth centuries, colonial administrators in Africa faced the daunting task of governing vast territories with diverse indigenous populations. To establish a semblance of legal order that was both manageable and minimally disruptive, European powers often adopted a policy of "indirect rule," relying on pre-existing indigenous legal systems, loosely termed "customary law." The prevailing anthropological and administrative paradigm of the era viewed these customary laws as static, ancient traditions that had been passed down unaltered through generations. Driven by a desire for bureaucratic uniformity, predictability, and legal certainty, colonial officials undertook extensive projects to codify these unwritten rules. They convened panels of local elders, whom they presumed to be the authentic repositories of uncorrupted tribal tradition, to articulate the specific rules governing property rights, marriage customs, and dispute resolution. Once recorded, these rules were formalized into written codes and rigorously applied in newly established colonial courts. For administrators, codification was viewed as a progressive, modernizing endeavor: it supposedly rescued indigenous law from the vagaries of human memory and provided a stable, predictable framework deemed essential for economic development and social administration. The resulting legal texts were treated as definitive, objective reflections of the societies' historical norms, providing the foundational justification for the colonial legal apparatus.

Passage B

Recent scholarship in legal history and anthropology has radically reassessed the nature of "customary law" as it was codified during the colonial era. Modern historians argue that the colonial understanding of indigenous legal systems rested on a fundamental misconception: the naive assumption that these systems were rigid, timeless, and unchanging. In reality, pre-colonial African legal systems were highly fluid, characterized by ongoing negotiation, contextual flexibility, and continuous adaptation to changing social and economic circumstances. When colonial administrators set out to codify these laws, they were not merely passively recording existing traditions; they were actively transforming them into something entirely new. By consulting a deliberately narrow demographic of older men—who often had a vested interest in consolidating patriarchal and gerontocratic authority over younger men and women—administrators formalized a version of "custom" that was far more rigid and authoritarian than the actual lived practices of the past. The very process of reducing dynamic, negotiated norms to fixed, written rules stripped customary law of its inherent flexibility and capacity for nuance. Consequently, the so-called "customary law" applied in colonial courts was less an authentic reflection of ancient tradition than a novel, hybridized legal framework co-created through the collaboration of European officials and local elites, primarily functioning to serve the systemic needs of colonial governance and social control.

Which one of the following best expresses the joint primary purpose of the two passages?

Read the short passage below regarding the history of musical notation. Based on the logical structure of the author's argument, arrange the following claims from the most foundational premise (the underlying factual cause) to the overarching main point (the final synthesis of the argument).

In the sixteenth century, the adaptation of musical notation for the newly invented printing press profoundly altered European musical culture. Traditional musicology has often viewed this transition merely as a technological acceleration of existing scribal practices, pointing out that early printed scores meticulously imitated manuscript styles. However, this perspective ignores the subtle, standardizing effects that the mechanical constraints of movable type imposed on composers. Because printers required standardized sets of musical symbols, the fluid, highly localized notations used by regional scribes were gradually replaced by a uniform system. This standardization, while initially appearing as a mere aesthetic homogenization, ultimately constrained the rhythmic complexities that composers could reliably communicate, thereby fostering a more uniform, less improvisational pan-European musical style.

Recently, the national retail chain BargainMart drastically reduced the variety of products it stocks, cutting its inventory from roughly 50,000 unique items to just 20,000. Surprisingly, despite offering far fewer choices to its customers, BargainMart's total revenue from sales increased by 15% over the exact same period, even though overall retail spending in the country remained flat.

Which one of the following, if true, most helps to resolve the apparent discrepancy described above?

Read the following passage.

In recent years, architectural historians have increasingly challenged the popular characterization of Brutalism as a fundamentally oppressive and dystopian design movement. Critics of Brutalism often point to its imposing concrete facades and association with bureaucratic state power as evidence of an anti-humanist agenda. However, this aesthetic critique fundamentally misinterprets the movement’s origins. As a close examination of post-war architectural manifestos reveals, Brutalism was conceived as an intrinsically utopian and egalitarian project. By utilizing inexpensive, unadorned materials, its pioneers sought to democratize architecture and construct accessible, functional civic spaces that rejected the elitist ornamentation of earlier eras. While many Brutalist structures ultimately suffered from chronic underfunding and neglect, their original intent was not to alienate the public, but rather to foster an inclusive, communal urban environment.

Which one of the following most accurately expresses the main point of the passage?

Read the following argument:

Mayor: To boost local tourism, we should allocate municipal funding to restore the historic Riverton Mill. Our neighboring town, Greendale, restored their historic train station last year, and they saw a 25 percent increase in tourist visits this summer. Therefore, restoring our mill will similarly increase Riverton's tourist visits.

Evaluate the following statement: The mayor's argument is actively weakened by the fact that Riverton's historic mill is structurally compromised and will require significantly more funding to restore than Greendale's train station did.

Passage A
For decades, researchers studying the placebo effect—the remarkable phenomenon where patients experience genuine clinical improvements after receiving completely inert treatments—have primarily relied on psychological frameworks to explain its mechanisms. According to the dominant psychological model, placebo responses are driven by two interrelated cognitive factors: conscious expectancy and classical conditioning. Expectancy theory posits that a patient's conscious belief in a treatment's efficacy directly influences their subjective experience of symptoms. If a patient is explicitly told that an inert sugar pill is a powerful analgesic, the anticipation of relief reduces the cognitive distress and anxiety associated with pain, thereby diminishing the perceived intensity of the pain itself. Classical conditioning complements this conscious expectation by suggesting that patients unconsciously associate the ritualistic elements of medical treatment—such as white coats, clinical environments, or the physical act of swallowing a pill—with healing, based on their past experiences with actual medications. In this view, the placebo effect is fundamentally a psychological mechanism, an intriguing product of the mind's ability to shape bodily experience through belief and learned mental associations. Therefore, any comprehensive analysis of alternative or placebo-based treatments must evaluate how effectively they harness these underlying cognitive and behavioral dynamics.

Passage B
The traditional view of the placebo effect as a predominantly psychological phenomenon—a subjective trick of the mind where patients simply convince themselves that they are feeling better—has been profoundly challenged by recent advances in neuroimaging and biochemistry. While psychological factors such as expectation undoubtedly play a role in initially triggering the response, the actual mechanism of action is distinctly and observably neurobiological. Functional magnetic resonance imaging (fMRI) studies have conclusively demonstrated that administering a placebo analgesic actively stimulates the brain's descending pain modulatory system, triggering the localized release of endogenous opioids, commonly known as endorphins. This neurochemical cascade is physiologically identical to the response produced by active pharmacological painkillers like morphine. Furthermore, clinical trials have shown that administering an opioid receptor antagonist such as naloxone completely blocks placebo-induced analgesia. This proves that the pain relief is not merely a subjective shift in the patient's attitude or a reduction in anxiety, but a quantifiable, receptor-mediated biochemical event. By demonstrating that placebos initiate specific, observable neurochemical changes in brain chemistry, researchers have established that the placebo effect is a hardwired physiological response. This biological validation shifts the focus of placebo research from the clinic's psychological environment to the laboratory's molecular mapping.

In the 1830s, the invention of the daguerreotype revolutionized visual documentation. Before its advent, portraits were exclusively the domain of wealthy patrons who could afford to commission oil paintings. The daguerreotype democratized portraiture by significantly reducing both the cost and the time required to produce a likeness. Photographers set up studios in major cities, attracting middle-class citizens eager to preserve their family heritage. Furthermore, the daguerreotype process yielded images of remarkable clarity and detail, surpassing the capabilities of earlier experimental photographic methods. Despite its popularity, the process had notable limitations: it required harsh chemicals, the images were fragile and had to be kept under glass, and each daguerreotype was a unique image that could not be easily reproduced.

According to the passage, all of the following were characteristics or consequences of the daguerreotype EXCEPT:

Prior to the widespread adoption of standardized coinage, economic exchange relied almost exclusively on the barter system, a mechanism fundamentally constrained by what economists term the "double coincidence of wants." In such a system, an individual possessing surplus grain and desiring cloth must locate not merely someone with surplus cloth, but specifically someone with surplus cloth who simultaneously desires grain. This structural inefficiency imposed severe transaction costs, limiting the scale of economic networks to localized communities where mutual needs could be more readily identified and fulfilled.

The introduction of minted currency in the first millennium BCE represented a profound conceptual leap. By establishing a universally accepted medium of exchange, societies decoupled the act of selling from the act of buying. A farmer could exchange grain for silver coins with one merchant, and subsequently use those coins to purchase cloth from another at a later date. This temporal and spatial flexibility drastically reduced the friction inherent in daily transactions. Furthermore, because standardized coins carried an intrinsic, verifiable value, merchants no longer needed to meticulously assess the quality of disparate goods offered in trade.

However, the implications of this monetary revolution extended far beyond the convenience of local marketplaces. As currency became widely recognized across varying political jurisdictions, the geographical constraints that had previously bound economic activity began to dissolve. Merchants, previously deterred by the logistical nightmare of transporting bulky surplus goods to distant regions in the mere hope of finding a willing barter partner, found their operations fundamentally transformed. Because wealth could now be condensed into portable, universally desirable units, __________________.

In examining the perturbation of high-alpine lentic ecosystems in the Sierra Nevada, biologists have elucidated a definitive trophic cascade triggered by the anthropogenic introduction of non-native salmonids. The primary mechanism of this disruption stems from the salmonids' selective predation on large cladoceran zooplankton, notably *Daphnia*. The extirpation of these robust grazers effectively abolishes the competitive suppression they typically exert on smaller, less efficient herbivorous zooplankton. Released from this constraint, the smaller zooplankton proliferate but fail to adequately control phytoplankton biomass. The subsequent exponential proliferation of phytoplankton engenders intense algal blooms that profoundly attenuate the penetration of solar radiation through the water column. This induced turbidity fundamentally alters the benthic habitat by inhibiting the photosynthesis of epilithic algae, thereby depleting the foundational nutritional resource upon which indigenous macroinvertebrate assemblages depend.

Based on the passage, arrange the following phenomena in the chronological order in which they occur as part of the causal chain initiated by the introduction of non-native salmonids.

Recent ecological research has fundamentally altered the traditional view of forests as arenas of strict competition, highlighting instead the profound cooperativity facilitated by mycorrhizal networks. These underground fungal networks colonize the roots of most tree species, creating a symbiotic web that pervades the forest floor. In this symbiosis, trees, which possess the photosynthetic capacity to produce carbohydrates, supply the fungi with essential carbon. In return, the extensive mycelial webs forage for water and soil nutrients—such as phosphorus and nitrogen—and deliver them to the host trees.

Crucially, these networks do not merely connect a single tree to its fungal partner; they link multiple trees, often of different species, into a complex system of resource exchange. Isotope tracing has demonstrated, for instance, that Douglas firs and paper birches transfer carbon back and forth depending on seasonal variations in sunlight. Furthermore, these networks serve as conduits for biochemical communication. When a tree is subjected to environmental stress, such as a drought or an aphid infestation, it can release defense-inducing chemical signals through the network, prompting neighboring trees to upregulate their own defensive enzyme production before the threat directly reaches them. Older, established trees, often termed 'hub trees,' play a particularly vital role by subsidizing shaded seedlings with surplus nutrients, thereby significantly enhancing the survival rates of the next generation.

According to the passage, the functions or benefits of mycorrhizal networks include all of the following EXCEPT which one?

Recent discoveries of early agricultural tools in the Andean highlands have prompted some anthropologists to argue that complex societies emerged there far earlier than previously believed. Proponents of this revised timeline point to carbon-dating of soil layers and distinctive wear patterns on the stone implements. However, these artifacts were found in an area known for severe geological uplifting, which routinely mixes soil layers and makes precise dating nearly impossible. Furthermore, similar wear patterns can easily be produced by natural erosion in harsh mountain environments. Because of these fundamental evidentiary issues, the claim that these tools represent an early complex society remains entirely speculative.

Which of the following best describes the author's attitude toward the claim that complex societies emerged earlier than previously believed in the Andean highlands?

In trust law, the doctrine of *cy pres* (Law French for "as near as possible") is invoked when a charitable trust's original purpose becomes impossible, impracticable, or illegal to execute. Historically, if a trust failed, the assets would revert to the donor's heirs via a resulting trust. However, courts developed *cy pres* to preserve charitable gifts by redirecting the funds to a purpose that closely approximates the donor's original intent. For a court to apply *cy pres*, it must determine that the donor had a "general charitable intent" rather than an intent exclusively tied to the specific, now-failed mechanism.

A classic application occurred when a 19th-century testator left a fund to combat diseases caused by "miasma" (bad air). When the miasma theory of disease was debunked and replaced by germ theory, fulfilling the exact terms of the trust became scientifically impossible. Rather than returning the endowment to the testator's distant relatives, the court applied *cy pres*. It reasoned that the donor's overarching goal was the improvement of public health through disease prevention. Consequently, the court authorized the redirection of the funds to a modern epidemiological research institute. Crucially, the court did not simply give the money to any worthy charity, such as an orphanage or an art museum, but strictly bound the new application to the closest modern equivalent of the original specific intent: fighting infectious diseases. Thus, *cy pres* functions as a conservative legal mechanism; it adapts to changing realities not by rewriting the donor's will to maximize social utility, but by interpreting the donor's original specific intent through the lens of modern circumstances.

Which of the following situations is most analogous to the application of the *cy pres* doctrine as described in the passage?

In contemporary jurisprudence, the debate between originalist and non-originalist interpretations of constitutional text often hinges on the concept of "original public meaning." Proponents of the new originalism argue that judges are bound not by the subjective intentions of the framers—a metric fraught with historical and psychological ambiguity—but rather by the objective meaning the constitutional text would have conveyed to a reasonable, informed citizen at the time of its ratification. This shift, its advocates claim, grounds constitutional interpretation in an empirical historical reality, thereby constraining judicial fiat and preserving the democratic legitimacy of the foundational document.

However, the pursuit of a singular "original public meaning" confronts a formidable historiographical hurdle: the semantic multiplicity inherent in any politically charged epoch. As legal historians point out, late eighteenth-century political discourse was rarely characterized by semantic consensus, particularly regarding the contested abstract concepts—such as "liberty," "due process," or "equal protection"—that form the bedrock of constitutional litigation. If a term possessed competing definitions among different factions of the ratifying public, elevating one specific historical understanding over others requires a normative choice by the modern interpreter, not merely a descriptive historical exercise.

Consequently, when confronting provisions where the historical record reveals deep conceptual divisions among the ratifying public, the new originalist methodology reaches an impasse. If the purported objective is to apply the text strictly according to its public meaning at ratification, yet the public at ratification was fundamentally fractured over that very meaning, the judge cannot simply "discover" the law through historical linguistics. In such instances, to resolve the interpretive dilemma without abandoning the originalist framework entirely, the adjudicator is logically forced to...

Carefully evaluate the following historical analysis regarding the transition from oral traditions to written records in early agrarian societies. Based on the author's line of reasoning, deduce the most appropriate verb to logically complete the final sentence of the passage.

During the transition from the Pleistocene to the Holocene epoch, the sudden return to glacial conditions known as the Younger Dryas was triggered by a complex interplay of hydro-glacial and oceanic mechanisms. As the Laurentide Ice Sheet rapidly retreated due to increasing global temperatures, vast quantities of fresh meltwater accumulated in proglacial Lake Agassiz. The catastrophic breaching of the lake's eastern ice dam redirected this massive freshwater pulse from the Mississippi River drainage system into the North Atlantic Ocean. Because freshwater is significantly less dense than saltwater, this influx stratified the surface waters of the North Atlantic, fundamentally disrupting the thermohaline circulation—the 'global ocean conveyor belt' driven by the sinking of cold, highly saline water. The resultant weakening of the Atlantic meridional overturning circulation drastically reduced the northward transport of equatorial heat. Consequently, despite the broader planetary warming trend, atmospheric temperatures in the Northern Hemisphere plummeted, initiating the millennium-long cooling phase of the Younger Dryas.

According to the passage, which one of the following explicitly caused the stratification of the surface waters in the North Atlantic?

In recent years, a growing chorus of legal historians has championed the "minimalist thesis" regarding the framing of the early constitutional amendments. Proponents of this thesis, most notably Elena Rostova, argue that the amendments were not intended to establish broad, universal principles of human rights, but rather were narrowly tailored political compromises designed to address specific, immediate grievances against the colonial power. Rostova points to the explicit omission of generalized language in the drafting debates as evidence that the framers sought to limit the scope of these provisions to very particular, historically contingent scenarios, essentially codifying the resolution of contemporary disputes rather than philosophizing for the ages.

There is a compelling elegance to this interpretation, and it offers significant interpretive utility. By anchoring the text strictly to the immediate historical context, the minimalist thesis provides a robust bulwark against the kind of unmoored judicial activism that often results from reading modern philosophical concerns into eighteenth-century documents. It forces courts and scholars alike to grapple with the actual historical record rather than abstract theoretical constructs. In doing so, it undeniably grounds constitutional jurisprudence in a more empirical, historically verifiable reality, acting as a necessary corrective to decades of overly romanticized scholarship.

However, one must be careful not to mistake a methodological corrective for a complete and exhaustive historical account. While Rostova is highly persuasive in demonstrating that the framers were pragmatic politicians addressing concrete problems, her framework struggles to account for the undeniable presence of expansive, natural-law rhetoric in the private correspondence and public speeches of several key framers, most prominently Madison and Jefferson. Furthermore, the sheer breadth of the language ultimately adopted in several of the amendments—such as the prohibition on "unreasonable" searches or the guarantee of "due process"—suggests at least some aspiration beyond the immediate redress of colonial-era grievances. If the framers' intent was as strictly and exclusively constrained as the minimalists claim, they chose singularly capacious language to express those constraints. Ultimately, while the minimalist thesis serves as an invaluable counterweight to overly expansive, anachronistic readings of the text, adopting it as the sole interpretive lens risks replacing one form of historical distortion with another, flattening the genuine philosophical complexity of the founding era into mere transactional politics.

Which of the following best describes the author's attitude toward the minimalist thesis championed by Elena Rostova?
