Time travel to the past has long fascinated physicists and philosophers alike, but it also ①generates a famously troubling contradiction. Suppose a traveler journeyed backward in time and, through some combination of accident and intention, ②prevented their own grandfather from ever meeting their grandmother. If the grandfather never had children, the traveler themselves would never have been born, which means the traveler could never ③existed to make the trip in the first place. Yet if the traveler never made the trip, the grandfather would have survived to meet the grandmother after all, ④allowing the traveler to be born and eventually travel back in time. The story therefore loops endlessly, undermining itself at every turn rather than ⑤settling into any stable outcome.

German sociologist Georg Simmel argued that the psychological experience of city life ①differ fundamentally from life in small towns, primarily because urban residents are bombarded with a much greater volume of stimuli than the human nervous system evolved ②to process. To cope with this constant sensory overload, Simmel proposed, city dwellers develop what he called a blasé attitude, a protective indifference in which individuals mentally blunt their emotional reaction to the surrounding crowd, ③treating most encounters with calculated detachment rather than genuine engagement. This detachment, while sometimes criticized as cold or impersonal, also grants urban residents a distinctive freedom, since so few people know or judge them ④personally. Simmel therefore viewed anonymity as a double-edged feature of modern life, one that isolates individuals from deep communal bonds while simultaneously ⑤liberating them from the constant surveillance of small-town social life.

Conventional economic wisdom holds that more options are always preferable to fewer, since a larger set of alternatives increases the likelihood that any individual will find one that precisely ①matches their preferences. Empirical research on consumer behavior, however, complicates this assumption considerably. When shoppers are presented with an extensive array of choices, they frequently experience heightened anxiety about making the wrong selection and, paradoxically, ②become less likely to make any purchase or decision at all. This phenomenon, commonly ③called choice overload, arises because evaluating numerous alternatives demands considerable cognitive effort, and the fear of forgoing a superior but unexamined option can overwhelm the pleasure of selecting from a limited set. Furthermore, individuals who do eventually choose from an overwhelming array often ④reports lower satisfaction with their selection than those who chose from a modest handful of options. Businesses that recognize this dynamic have begun deliberately ⑤curating smaller, carefully selected assortments.

A plastic bag that fully decomposes within months rather than lingering for centuries sounds almost too convenient to be real, yet certain bioplastics on the market ①do exactly that under the right conditions. Unlike conventional plastic, derived almost entirely from petroleum, many bioplastics are ②synthesized from renewable feedstocks such as corn starch or sugarcane, sometimes with the help of bacteria engineered to produce plastic-like polymers as a byproduct of their metabolism. Not every bioplastic biodegrades quickly, however, and some marketed as eco-friendly break down only in industrial composting facilities ③that reach conditions rarely found in a backyard compost heap or the open ocean. Critics point out that growing crops for bioplastic production can compete with food crops for farmland and water, ④complicating the assumption that a biological origin automatically makes a material more sustainable. Researchers are now exploring bioplastics made from agricultural waste and algae instead of dedicated crops, hoping to ⑤sidestepping this competition for land while preserving the benefits that first made bioplastics appealing.

Long before humans learned to drill for oil, microorganisms had already ①mastered the art of converting sunlight and carbon dioxide into stored chemical energy. Modern biofuel research borrows this ability, cultivating algae or engineered bacteria in large tanks where they can be coaxed into producing oils and sugars that can be ②refined into fuel usable in existing engines. Unlike crops grown for corn-based ethanol, which ③compete directly with food production for arable land, many algae strains can thrive in shallow ponds, wastewater, or even coastal seawater unsuitable for conventional agriculture. Engineers have also learned to tinker with the metabolic pathways of these organisms, boosting oil yield far beyond what any wild strain would naturally produce on its own. Despite this progress, producing biofuel at a cost competitive with fossil fuel remains ④difficult, since harvesting and processing the organisms ⑤conserves a substantial share of the energy the fuel itself will eventually provide.

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. Life cycle assessment, commonly abbreviated as LCA, _______________. 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. 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. Without accounting for these earlier stages, a superficial comparison could mistakenly present the vehicle as entirely emission-free. Therefore, researchers increasingly rely on life cycle assessment to make informed decisions rather than trusting labels alone.

Students are frequently told that where they study makes little difference, provided that they put in enough hours. Cognitive research on memory retrieval, however, suggests that this advice oversimplifies an important process. According to the encoding specificity principle, information becomes intertwined with the context in which it was originally learned. Cues present during encoding therefore facilitate retrieval far more effectively than cues encountered elsewhere. A striking demonstration involved divers who memorized word lists either underwater or on dry land. When tested later, _______________. This held true regardless of which environment that happened to be. This finding implies that reviewing material exclusively in a quiet bedroom may not adequately prepare a student for the noisy atmosphere of an actual examination hall. Rather than assuming that memorization is a context-free process, students ought to consider deliberately varying study locations and conditions. Doing so would ensure that retrieval cues remain available regardless of how a future test is administered.

For this reason, many economists argue that the real challenge is not the robots themselves, but the speed at which society is expected to adapt to them. Factories that once employed hundreds of workers on an assembly line now run with a fraction of that staff, as robotic arms handle tasks that used to require human hands. ( ① ) Economists have long debated whether this shift destroys jobs or simply transforms them. ( ② ) Historical evidence offers some comfort: previous waves of automation eventually created new categories of work that no one had predicted. ( ③ ) However, critics point out that earlier transitions unfolded over generations, giving workers time to retrain, whereas today's robots are being deployed at a pace that leaves little room for adjustment. ( ④ ) A factory worker displaced this year cannot simply wait for a new industry to emerge decades from now. ( ⑤ )

Because the donkey is assumed to be a perfectly rational creature that always chooses the option supported by the strongest reason, it finds itself, in this case, with no rational basis for choosing either pile. Medieval philosophers told the story of a hungry donkey placed exactly midway between two identical, equally fragrant piles of hay, with no factor whatsoever tipping the balance toward either option. ( ① ) Neither pile offers any advantage over the other. ( ② ) Paralyzed by this perfect symmetry, the donkey starves to death precisely because it can find no reason to move in either direction. ( ③ ) Critics of the story point out that real animals, and real humans, rarely face situations of such flawless symmetry. ( ④ ) Even a tiny, arbitrary preference, they note, is usually enough to break the tie in practice. ( ⑤ ) The paradox nevertheless raises a serious question about whether purely rational deliberation can ever generate action on its own.

주어진 문장: This effect was first demonstrated systematically through a series of controlled laboratory experiments conducted in the 1970s. Eyewitness testimony has long carried weight in courtrooms, yet decades of research reveal that memories of witnessed events are more malleable than most people assume. ( ① ) When individuals who observe an event are later exposed to misleading information about what they saw, whether through a leading question or a conversation with another witness, their recollections frequently incorporate details that never occurred, a phenomenon known as the misinformation effect. ( ② ) In one classic paradigm, participants who watched a video of a traffic accident and were then asked how fast the cars were going when they smashed into each other reported higher speed estimates and were more likely to falsely recall broken glass than participants asked the identical question using the milder verb hit. ( ③ ) Crucially, these distorted memories often feel genuine to the person experiencing them, since the original memory trace becomes blended with the newly introduced information rather than existing as a separate, contradictory record. ( ④ ) Such findings have prompted legal systems to adopt cautious interviewing protocols designed to minimize suggestive questioning during investigations. ( ⑤ )
