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.

Facing a shortage of caregivers and a rapidly aging population, several countries have begun deploying robots designed to remind elderly residents to take medication, monitor for falls, and even offer simple conversation throughout the day. Early trials show that many residents report ①reduced loneliness, particularly when a robot's presence allows an overworked human staff member to spend a few extra minutes with each patient rather than rushing between rooms. Critics, however, worry that this framing quietly ②shifts the goal of care: instead of asking how technology can support human connection, institutions may come to treat a robot's companionship as an ③unacceptable substitute for it. Advocates for the elderly argue that robots should be evaluated strictly as tools that free up human time for human contact, ④never as a lower-cost replacement for the contact itself, since human presence remains ⑤irreplaceable.

As more schools shift toward digital textbooks and online assignments, a student without reliable internet access at home faces a disadvantage that has little to do with talent or effort. During recent years, this gap became ①impossible to ignore, as families in rural areas or low-income neighborhoods struggled to complete schoolwork that assumed a stable connection and a personal device. Some policymakers initially treated internet access as a ②convenience, comparable to cable television, rather than as infrastructure essential to modern life. That assumption is increasingly being reconsidered, particularly as more essential services move online by default. Closing this divide will require ③far less than simply distributing devices; it will demand ④sustained investment in the physical networks that carry information into every home, ⑤regardless of income or location.

Many large companies now rely on artificial intelligence to screen job applications before a human ever sees them. These systems promise efficiency, scanning thousands of resumes in seconds and ranking candidates according to patterns drawn from previous hiring decisions. However, this reliance on historical data creates a troubling risk. If a company's past hiring favored a particular group, the algorithm may learn to treat that pattern as a marker of success and quietly reproduce it, even when no one intended discrimination. Unlike a human interviewer, the system offers no explanation for its choices, which means that _______________. Some researchers argue that fairness cannot be added afterward; it must be built into the system's design from the very beginning.

Philosophers often pair the classic trolley problem with a companion case designed to test whether our moral intuitions are actually consistent. Imagine a brilliant surgeon who has five patients, each dying from the failure of a different organ, and one healthy visitor in the waiting room whose organs happen to be a perfect match for all five. If the surgeon secretly killed the healthy visitor and transplanted the organs, five lives would be saved at the cost of one, exactly the same arithmetic used to justify diverting a runaway trolley onto a track with a single worker. Yet almost everyone who accepts the trolley diversion recoils immediately at the idea of the surgeon cutting up an unwilling patient, even though the numbers are identical in both cases. Philosophers use this contrast to argue that _______________.

The role of emotion in decision-making carries important implications for how financial advice should be delivered. (A) An advisor who presents only statistical projections and probability distributions, however accurate, may fail to help a client translate that information into a decision that feels manageable rather than overwhelming. (B) Effective financial communication, therefore, often pairs quantitative analysis with reassurance calibrated to the client's emotional state, particularly during periods of market turbulence. (C) Clients facing significant financial decisions are rarely persuaded by numbers alone, since anxiety about an uncertain outcome can override even a clear rational case for a particular course of action.

A few years ago, spotting a manipulated video required a trained eye and specialized software. (A) Perhaps more troubling than any single fake video is the broader effect on public trust, sometimes called the liar's dividend, in which genuine footage can be dismissed as fabricated simply because deepfakes exist. (B) Today, freely available applications allow almost anyone to swap a face or fabricate a voice convincingly enough to fool casual viewers within minutes. (C) This shift has quietly undermined one of the oldest assumptions in human communication: that seeing and hearing something is a reliable way to confirm it happened.

It would be comforting to believe that anything sufficiently large or obvious appearing within our field of vision will automatically capture our attention, yet decades of research into inattentional blindness suggest otherwise. (A) This failure does not stem from a defect in the eyes, which register the stimulus perfectly well, but from the fact that conscious perception depends heavily on where attention has been directed. (B) When people are absorbed in a demanding task, such as counting how many times a ball is passed between players, they frequently fail to notice an unexpected and conspicuous event unfolding in plain sight, even something as unlikely as a person in a costume walking through the scene. (C) Policymakers ought to take this finding more seriously than they currently do, because it implies that simply placing a warning sign within someone's visual range offers no guarantee that it will be consciously registered. Designing safer environments, therefore, requires accounting for the limits of attention itself, not merely assuming that visibility alone ensures awareness.

Every time a smartphone connects to a cell tower or a Wi-Fi network, it quietly records a data point that can later be pieced together into a detailed map of where its owner has been. (A) Companies often argue that anonymized data cannot be traced back to individuals, yet researchers have repeatedly shown that a handful of location points is enough to identify a specific person. (B) Most users agree to this tracking without reading the fine print, assuming that a single company's database poses little threat. (C) The real danger, however, emerges when location data from multiple sources is combined, revealing a person's home, workplace, and daily route.

주어진 문장: Such admiration is common, for instance, toward chess grandmasters, medical diagnosticians, or professional musicians who seem to recall vast bodies of specialized knowledge without visible strain. When people encounter an individual who appears to memorize enormous quantities of specialized information effortlessly, they often assume that person possesses an innate gift. ( ① ) Cognitive psychologists, however, contend that such feats rarely stem from raw talent alone. Instead, such feats arise from a learned skill known as chunking, whereby scattered pieces of information are consolidated into larger, meaningful units. ( ② ) A landmark study of chess players demonstrated this principle. When shown a board arranged according to plausible game positions, grandmasters reproduced the layout perfectly. ( ③ ) Yet when the same pieces were scattered randomly, their performance collapsed to the level of novices. This pattern reveals that expert memory is not larger in raw capacity but is instead organized around patterns accumulated through years of deliberate practice. ( ④ ) If chunking, rather than innate aptitude, underlies expert performance, then educators should stop treating talent as fixed and destiny-bound. ( ⑤ ) Curricula ought to be redesigned to cultivate pattern recognition explicitly, since doing so would grant far more students access to expertise once presumed reserved for the naturally gifted.
