When a resource is shared among many users, none of ①whom bears the full cost of its depletion, each individual is tempted to extract as much value as possible before others do the same. This dynamic, famously ②labeled the tragedy of the commons, describes how shared pastures and fisheries can be degraded even when every participant privately understands the danger of overuse. A single herder who adds one more animal to a communal pasture gains the entire benefit of that addition, whereas the resulting damage to the grass ③is shared among other herders who depend on the land. Because self-interest offers no incentive to restrain consumption unilaterally, the resource tends ④to exhausted long before any user intends such an outcome. For decades, economists assumed that only two remedies existed: strict regulation or the conversion of shared resources into private property. Elinor Ostrom challenged this assumption, however, by ⑤documenting communities that had sustainably managed fisheries and forests for generations through locally devised rules and mutual monitoring rather than external control.

The human gut hosts trillions of microorganisms ①whose combined genetic material outnumbers that of the human genome itself many times over. Once dismissed as passive hitchhikers, these bacteria are now understood ②to actively shape digestion, regulate immune responses, and even influence the production of chemicals that affect mood and behavior. A microbiome disrupted by antibiotics, poor diet, or chronic stress can leave the gut lining more permeable than it should be, ③allowing substances to leak into the bloodstream that would normally stay contained. Researchers studying this connection have found that transplanting gut bacteria from a healthy donor into a patient can, in some cases, relieve symptoms of certain digestive disorders that conventional medication ④had failed to treat. Still, scientists caution that the microbiome varies enormously between individuals, which means a treatment that restores balance in one person's gut may ⑤does little for someone else's.

Consider a large heap containing ten thousand grains of sand. Nearly everyone agrees that removing a single grain from such a heap leaves another heap behind; surely one grain could never make the difference between a heap and a non-heap. Yet if this principle is applied repeatedly, grain by grain, the heap eventually shrinks to a single lonely grain, or even to no grains at all, and logic alone seems to force us to accept that this final result still counts as a heap. Something has clearly gone wrong along the way, since no reasonable person would call one grain of sand a heap, but pinpointing exactly which single removal transformed a heap into a non-heap seems impossible. The puzzle exposes a deep discomfort with vague terms like "heap," "tall," or "bald," concepts that seem to admit no sharp boundary yet are used confidently in everyday language. Some philosophers conclude that _______________.

Sociologist Mark Granovetter challenged a common assumption when he found that job seekers were more likely to hear about new opportunities from casual acquaintances than from close friends and family. This finding, published as the strength of weak ties, rests on a structural insight: close friends tend to belong to the same tight social circle and therefore already share most of the same information, whereas casual acquaintances typically move in different circles and can act as bridges to information a person would otherwise never encounter. Weak ties, precisely because they connect otherwise separate networks, _______________. Granovetter's insight has since been applied well beyond job searches, informing research on how innovations spread and how epidemics travel through a population.

The eventual collapse of a speculative bubble often unfolds with surprising speed compared with the gradual climb that preceded it. (A) As prices begin to fall, investors who bought near the peak, motivated largely by fear of missing further gains, are often the first to sell, since they have the least conviction in the asset's underlying value. (B) Their selling triggers further price declines, which in turn prompt additional investors to sell out of a newly urgent fear of continued loss rather than a fear of missing out. (C) This reversal illustrates that the same herd psychology driving prices upward can just as easily reverse direction, converting collective optimism into collective panic within a remarkably short period.

Dual coding theory, first proposed to explain why certain kinds of information are remembered more readily than others, holds that the mind processes verbal and visual material through two partially independent channels rather than a single unified system. (A) Consequently, dual coding theory has profound implications for instructional design, suggesting that combining carefully chosen visuals with concise verbal explanations can strengthen students' long-term retention of complex material. (B) According to this account, words and other linguistic symbols are encoded primarily through a verbal channel that represents meaning in an abstract, sequential form, while pictures and concrete objects are encoded through an imagery channel that preserves spatial and perceptual detail. (C) When information engages both channels simultaneously, as when a textbook pairs a written explanation with an accompanying diagram, the resulting memory trace benefits from two separate, mutually reinforcing pathways of retrieval rather than just one. This redundancy explains the well-documented picture superiority effect, whereby concrete, easily visualized words tend to be recalled more accurately than abstract terms that resist mental imagery.

In other words, people want the safest outcome for society in theory, but the safest outcome for themselves in practice. When engineers design the software that controls a self-driving car, they inevitably face a question that philosophers have debated for decades. ( ① ) If a crash becomes unavoidable, should the vehicle protect its own passenger at all costs, or should it be programmed to minimize total harm, even if that means steering toward the person inside? ( ② ) Surveys reveal an uncomfortable contradiction: most people say a car should be programmed to save the greater number of lives. ( ③ ) Yet the same people admit they would never buy a vehicle designed to sacrifice its own owner. ( ④ ) This gap between the ideal and the personal choice suggests that ethical programming cannot be settled by public opinion alone. ( ⑤ ) Manufacturers, regulators, and philosophers must instead agree on transparent rules before autonomous vehicles are allowed to make such decisions.

주어진 문장: Taken together, these shortcomings suggest that biodegradability alone cannot guarantee a meaningful reduction in plastic pollution. Biodegradable plastics have been promoted as a promising solution to plastic waste, since they are designed to decompose into natural substances rather than persist for centuries. ① Manufacturers derive these materials from renewable resources such as corn starch, blending them with additives that accelerate microbial breakdown once discarded. ② However, their environmental benefits are often exaggerated, largely because decomposition depends on specific conditions rarely found outside industrial composting facilities. ③ 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. ④ In addition, when mixed with conventional plastics in recycling streams, they can contaminate the process, weakening the quality of materials produced afterward. ⑤ 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 providing the precise conditions decomposition demands. ① ② ③ ④ ⑤

주어진 문장: In other words, no phase of a product's existence is excluded from consideration, from the extraction of raw materials to its final disposal. When consumers compare two products and assume that the one labeled "eco-friendly" is automatically the more sustainable choice, they often overlook the complexity involved in verifying such a claim. ① Life cycle assessment, commonly abbreviated as LCA, is a systematic method developed to evaluate the environmental impact of a product across every stage of its existence. ② This method examines raw material extraction, manufacturing, transportation, use, and disposal, compiling data on energy consumption and emissions generated at each stage. By tracing a product from its origin to its disposal, this approach reveals impacts that might otherwise remain hidden from consumers who see only the finished item on a shelf. ③ For example, an electric vehicle may produce no emissions while being driven, yet the mining of metals for its battery can generate substantial environmental costs elsewhere. ④ Without accounting for these earlier stages, a superficial comparison could mistakenly present the vehicle as entirely emission-free. ⑤ Therefore, researchers increasingly rely on life cycle assessment to make informed decisions rather than trusting labels alone. ① ② ③ ④ ⑤

주어진 문장: This selective compression of memory is not random, however; it follows a strikingly predictable psychological pattern. When people look back on a multi-day journey, they rarely recall every hour with equal clarity; instead, memory tends to compress the entire experience into just a few representative moments. ( ① ) Psychologists have found that two points carry disproportionate weight in this process: the single moment when emotion, whether joy or discomfort, reached its highest intensity, and whatever happened right before the experience concluded. ( ② ) Consider two hikers who complete an identical five-day trek. ( ③ ) The first finishes with a grueling, rain-soaked final climb, while the second enjoys a calm, scenic descent on the last afternoon despite having endured an equally difficult ascent earlier in the trip. ( ④ ) Even though both hikers faced comparable hardship overall, the second is far more likely to remember the journey fondly, simply because the trip ended pleasantly. ( ⑤ ) This pattern reveals that overall satisfaction is not calculated as an average of every experienced moment; rather, it is shaped disproportionately by whichever moments felt most intense and by however the experience happened to end.
