문제 1

The immune system produces an almost limitless variety of antibodies, each ①shaped to latch onto one particular molecular target with remarkable specificity. Monoclonal antibody drugs harness this natural precision by cloning a single antibody-producing cell in the laboratory, ②generating 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 effectively than traditional chemotherapy, ③which attacks any rapidly dividing cell regardless of whether it is cancerous. Manufacturing monoclonal antibodies remains far more complicated than producing a conventional small-molecule pill, since living cells must ④cultivating in carefully controlled bioreactors for weeks before the antibody can be purified and prepared for use. This complexity keeps monoclonal antibody treatments considerably more expensive than most conventional drugs, a cost that continues ⑤to shape debates over pricing and access.

문제 2

Suppose you meet a quiet, ①gentle man who speaks softly, tends a small garden, and organizes his bookshelf with meticulous care. Asked whether he is more likely a florist or a truck driver, most people ②instinctively choose florist, since his personality matches the stereotype so neatly. This judgment, however, ignores a crucial fact: truck drivers vastly ③trail florists in almost every country, which means that, statistically, he is far more likely to belong to the larger group regardless of how well he fits the flower-shop image. Relying on resemblance to a familiar category rather than on underlying numerical proportions, known among researchers as representativeness, leads people to overlook these base rates almost ④automatically. Even trained professionals, who should know better, often fall into the same trap when a vivid description feels more ⑤convincing than plain statistics.

문제 3

People routinely seek out information that confirms what they already believe while ①overlooking or dismissing evidence that contradicts those beliefs, a pattern known as confirmation bias. This tendency operates not because individuals are deliberately dishonest, but because the mind finds it cognitively less ②taxing to absorb information that fits an existing framework than to reconstruct that framework from scratch. Investors who believe a particular company will succeed, for instance, tend to interpret ambiguous news about that company ③unfavorably, while investors who are skeptical of the same company interpret identical news unfavorably, even though both groups are examining the same underlying facts. Social media platforms can ④intensify this effect by algorithmically presenting users with content similar to what they have previously engaged with. Over time, such selective exposure can harden initial impressions into convictions that feel objectively verified, even though they rest on a systematically ⑤filtered sample of evidence.

문제 4

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.

문제 5

Generative AI systems learn to write, draw, and compose by studying ①enormous collections of existing human work, much of which was created without the artists' knowledge or consent. Supporters of the technology argue that this process resembles how a human student learns by studying the masters, ②absorbing style and technique rather than copying specific pieces. Critics respond that the comparison ③holds up perfectly at scale, since a single AI model can absorb millions of works in days. Courts around the world are now being asked to decide whether training an algorithm on copyrighted material counts as fair use or as ④infringement. Until clearer rules emerge, artists, developers, and publishers remain locked in a legal ⑤gray zone that satisfies almost no one.

문제 6

Every time an antibiotic kills off a population of bacteria, a handful of cells carrying a random mutation that resists the drug are left behind to ①multiply without competition. Repeated over decades, across hospitals, farms, and households worldwide, this simple process of natural selection has produced strains of bacteria that survive treatments once considered reliably ②effective. The pharmaceutical industry, meanwhile, has slowed the pace at which new antibiotics reach the market, since a drug meant to be taken for only a week or two rarely earns back the ③enormous cost of developing it. Researchers are therefore searching in ④unconventional places, screening soil microbes, ocean sediment, and even genetic databases for molecules that kill bacteria through mechanisms resistant strains have not yet learned to evade. Some scientists have also revived an older approach, using viruses that infect only bacteria to hunt down resistant strains with a ⑤carelessness no broad-spectrum drug could ever match.

문제 7

When a resource is shared among many users, none of whom bears the full cost of its depletion, each individual is tempted to extract as much value as possible before others do the same. (A) This dynamic, famously labeled the tragedy of the commons, describes how shared pastures and fisheries can be degraded even when every participant privately understands the danger of overuse. (B) 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 is shared among other herders who depend on the land. Because self-interest offers no incentive to restrain consumption unilaterally, the resource tends to be exhausted long before any user intends such an outcome. (C) 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 documenting communities that had sustainably managed fisheries and forests for generations through locally devised rules and mutual monitoring rather than external control.

문제 8

Devices that translate brain activity directly into digital commands have moved from laboratory experiments to real medical use, allowing paralyzed patients to control a robotic arm using thought alone. (A) This prospect raises a philosophical question that medicine alone cannot answer: at what point does the assistance stop being a tool and start reshaping the identity of the person using it? (B) As the technology improves, some developers envision a future in which these interfaces extend beyond restoring lost function toward enhancing healthy minds. (C) Neuroethicists argue that mental privacy may need to be recognized as a fundamental right before this technology becomes widespread.

문제 9

A struggling artist may judge success not against neighbors but against celebrated painters in art history, a comparison that can inspire ambition or, just as easily, breed persistent dissatisfaction. Individuals rarely evaluate their own lives in isolation; instead, they measure their achievements, possessions, and status against a reference group, a set of people they use as a standard for comparison. ( ① ) This group need not be one to which a person actually belongs. ( ② ) Sociologists distinguish between normative reference groups, which shape a person's values and behavior, and comparative reference groups, which merely provide a benchmark for self-assessment. ( ③ ) Robert Merton showed that soldiers who compared their promotion chances to peers within their own slow-moving unit often felt more satisfied than soldiers in units with faster promotion rates. ( ④ ) This counterintuitive finding demonstrates that satisfaction depends less on objective circumstances than on the group against which those circumstances are measured. ( ⑤ )

문제 10

주어진 문장: As a result, no single boundary can be evaluated in isolation from the others. Scientists have long searched for a way to describe, in a single coherent framework, the outer limits within which human activity can safely continue without destabilizing the planet's fundamental systems. ① The concept of planetary boundaries, introduced by earth-system researchers, identifies nine interconnected processes, including climate change, biodiversity loss, and nitrogen pollution, each possessing a threshold beyond which abrupt and irreversible change becomes likely. ② Unlike conventional environmental limits, often defined locally, these boundaries are framed at a planetary scale, reflecting the idea that the Earth functions as a single interdependent system rather than a collection of isolated regions. ③ Crossing one boundary, proponents argue, does not merely damage the system involved but can also destabilize others, since climate, oceans, and land are bound together by feedback loops that transmit disturbance across the system. ④ Some philosophers have likened this framework to a ship's safe operating margin, within which passengers may move freely without risking the vessel's stability. ⑤ Critics, however, contend that the boundaries are drawn with more confidence than the data can support. ① ② ③ ④ ⑤
