Biodegradable plastics have been promoted as a promising solution to plastic waste, since they ①are designed to decompose into natural substances rather than persist for centuries. Manufacturers derive these materials from renewable resources such as corn starch, blending them with additives that ②accelerates microbial breakdown once discarded. However, their environmental benefits are often exaggerated, largely because decomposition depends on specific conditions rarely ③found outside industrial composting facilities. For example, a bag labeled biodegradable may take years, not the weeks advertised, to break down in a landfill or ocean, where temperature and microbial activity remain low. In addition, when mixed with conventional plastics in recycling streams, they can contaminate the process, ④weakening the quality of materials produced afterward. Some engineers therefore compare biodegradable plastics to a bridge that leads nowhere unless paired with infrastructure that completes the journey. Ultimately, realizing their genuine potential requires not only technological refinement but also facilities capable of ⑤providing the precise conditions decomposition demands.

Over the past two decades, insights drawn from behavioral economics have moved beyond academic journals and into the machinery of government itself, reshaping how numerous public programs are designed and implemented. Tax authorities in several countries, for example, discovered that simply informing citizens how many of their neighbors had already paid overdue taxes on time substantially ①increased subsequent compliance rates, outperforming letters that merely threatened legal penalties for continued nonpayment. Public health agencies have applied similar principles to encourage preventive care, finding that appointment reminders phrased to emphasize the personal cost of a missed visit proved more ②ineffective than neutral reminders listing only the date and time. Employment offices redesigned job-seeking assistance programs around specific, actionable steps rather than general encouragement, discovering that participants who were asked to write down a concrete plan for the following week were considerably more likely to follow through than those who received only ③general advice. What unites these disparate interventions is a shared recognition that small, carefully tested adjustments to how choices are presented can produce measurable improvements in outcomes, often at a fraction of the cost required by traditional programs involving substantial financial incentives or extensive ④enforcement. This accumulated evidence has encouraged many governments to establish dedicated units tasked with applying behavioral insights ⑤systematically to policy problems across an increasingly broad range of domains.

As buildings account for a substantial share of global energy consumption, architects have increasingly turned to a design philosophy known as the passive house standard, which ①minimizes energy demand through the building's own structure rather than through mechanical systems. Central to this approach is airtight construction, in which continuous insulation and sealed joints prevent conditioned air from leaking outward, thereby ②reducing the heating and cooling loads conventional buildings require. Triple-glazed windows, oriented to capture sunlight in winter while shading interiors in summer, further ③destabilize indoor temperatures without relying heavily on furnaces or air conditioners. Ventilation systems equipped with heat exchangers also recover warmth from outgoing air, transferring it to incoming air so that comfort is maintained without ④excessive energy use. For example, some passive houses built in cold climates have reduced heating costs by more than ninety percent. Consequently, many architects regard passive house design not as a luxury for wealthy homeowners but as a practical model ⑤capable of reshaping mainstream construction.

The immune system produces an almost limitless variety of antibodies, each shaped to latch onto one particular molecular target with remarkable ①specificity. Monoclonal antibody drugs harness this natural precision by cloning a single antibody-producing cell in the laboratory, generating an army of identical antibodies built to recognize one target, such as a protein on a cancer cell or a molecule driving an autoimmune disease. Because the antibody binds only to its intended target, these drugs tend to spare healthy tissue far more ②effectively than traditional chemotherapy, which attacks any rapidly dividing cell regardless of whether it is cancerous. Manufacturing monoclonal antibodies remains far more ③complicated than producing a conventional small-molecule pill, since living cells must be cultivated in carefully controlled bioreactors for weeks before the antibody can be purified and prepared for use. This complexity keeps monoclonal antibody treatments considerably more ④expensive than most conventional drugs, a cost that continues to ⑤resolve debates over pricing and access.

Working memory refers to the mental workspace in which information is temporarily held and manipulated while a person performs a cognitive task. Such tasks include solving an arithmetic problem, following a rapid conversation, or holding a phone number in mind before dialing it. In the mid-twentieth century, the psychologist George Miller proposed that this workspace could accommodate roughly seven discrete items. His claim proved so influential that it became widely known as the magic number seven. Subsequent research, however, revealed that Miller's estimate was somewhat generous, since it failed to account for the complexity of the material being remembered. Nelson Cowan later argued that when rehearsal strategies are prevented and attention is tightly controlled, _______________. This discrepancy suggests that what earlier studies had measured was not raw storage capacity itself but a hybrid quantity inflated by clever strategies. Contemporary psychologists therefore distinguish between the fixed limit of working memory and the flexible techniques that allow individuals to transcend that limit.

As private companies develop the technology to mine asteroids for rare metals and water, a legal question has become urgent: who owns the resources of outer space? Existing international treaties state that no nation may claim sovereignty over celestial bodies, but they say remarkably little about whether a private company may extract and sell what it finds there. Some governments have already passed domestic laws granting their own companies rights to material mined in space, a move that other nations view as _______________.

Generative AI systems learn to write, draw, and compose by studying enormous collections of existing human work, much of which was created without the artists' knowledge or consent. (A) Critics respond that the comparison breaks down at scale, since a single AI model can absorb millions of works in days and compete with the very artists who trained it. (B) Supporters of the technology argue that this process resembles how a human student learns by studying the masters. (C) Courts around the world are now being asked to decide whether training an algorithm on copyrighted material counts as fair use or as infringement.

Cities are frequently several degrees warmer than the surrounding countryside, a phenomenon known as the urban heat island effect, which intensifies in summer and threatens public health. (A) This disparity arises largely because asphalt and concrete absorb solar radiation during the day and slowly release it as heat throughout the night, preventing urban areas from cooling down. Furthermore, the scarcity of vegetation in densely built areas removes a natural cooling mechanism, since plants lower temperatures by evaporating water from their leaves. (B) Another strategy, green infrastructure, incorporates rooftop gardens and tree-lined streets that provide shade while releasing moisture. In contrast, some cities have pursued permeable pavements that let water seep through and evaporate, cooling nearby surfaces. Collectively, these strategies show that reducing urban heat depends on combining approaches suited to a city's geography. (C) To address this problem, urban planners have begun implementing mitigation strategies designed to lower surface and air temperatures. One widely used solution involves reflective "cool" roofing engineered to reflect more sunlight than dark rooftops absorb.

This arrangement becomes especially troubling when health data influences decisions far beyond fitness, such as insurance premiums or employment screening. Millions of people now wear devices that continuously track their heart rate, sleep patterns, and daily activity, generating an intimate stream of health data. ( ① ) Users generally assume this information belongs to them, since it is drawn directly from their own bodies. ( ② ) In practice, however, the terms of service that few people read often grant the manufacturer broad rights to store, analyze, and even sell anonymized versions of that data to insurers or advertisers. ( ③ ) Advocates for reform argue that biological data deserves a category of protection stronger than ordinary consumer information. ( ④ ) This is precisely because it can never truly be replaced or reset once it has been exposed. ( ⑤ )

Robert Merton refined this framework by distinguishing manifest functions, the intended and openly recognized consequences of a social practice, from latent functions, unintended consequences that nonetheless help sustain the system, such as schools serving not only to educate but also to provide childcare that allows parents to work. Structural functionalism approaches society as a complex system of interdependent parts, each contributing to the overall stability and smooth operation of the whole, much as organs contribute to the survival of a biological body. ( ① ) Sociologist Talcott Parsons argued that institutions such as the family, education, religion, and government each perform necessary functions, socializing new members and transmitting values. ( ② ) Removing or weakening any one institution, in his view, threatens the equilibrium of the entire system. ( ③ ) Critics have long charged that functionalism, by emphasizing stability and equilibrium, struggles to explain social conflict and rapid change. ( ④ ) It tends to interpret persistent inequality as somehow functional for society rather than as a problem requiring correction. ( ⑤ )
