For decades, most vaccines worked by ①injecting a weakened or inactivated version of a pathogen, coaxing the immune system into recognizing an enemy it had never truly fought. mRNA vaccines take a fundamentally different route, ②delivering only a short genetic instruction wrapped in a protective lipid capsule, one that tells the body's own cells how to manufacture a single harmless piece of a virus's outer surface protein. Once those cells display the fragment, the immune system learns to recognize it as foreign and ③builds a defense, without ever having encountered the actual pathogen. Because the vaccine contains no live virus and cannot alter a cell's own DNA, developers can redesign the genetic instructions within weeks whenever a pathogen ④mutating, rather than starting the years-long process required for traditional vaccines. This speed, first proven on a global scale during a recent pandemic, has convinced many researchers that the same platform could eventually ⑤be adapted to fight diseases far beyond infectious illness, including certain cancers.

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. This group ①need not be one to which a person actually belongs. A struggling artist may judge success not against neighbors but against celebrated painters in art history, a comparison ②that can inspire ambition or, just as easily, breed persistent dissatisfaction. Sociologists distinguish between normative reference groups, which shape a person's values and behavior, and comparative reference groups, ③which merely provide a benchmark for self-assessment. 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, because the latter could see colleagues ④advance while they themselves ⑤lagging behind.

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.

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.

A small bakery once sold a basic loaf for three dollars and a premium loaf for six dollars, and most customers simply bought the cheaper one. The owner then introduced a third option: a slightly larger premium loaf priced at seven dollars, one that was clearly inferior to the six-dollar loaf in terms of value for money. Almost nobody chose the new seven-dollar loaf, yet sales of the six-dollar loaf rose sharply, because _______________. This pattern demonstrates that people rarely judge options in isolation; instead, they evaluate choices relative to whatever alternatives happen to be nearby.

Symbolic interactionism approaches society not as a fixed structure imposed from above but as something continuously constructed through everyday face-to-face interaction, in which individuals interpret and respond to the symbolic meanings that objects, actions, and other people hold for them. Sociologist George Herbert Mead argued that the self itself emerges through this interactive process, as individuals learn to see themselves from the perspective of others. Erving Goffman extended this framework with his dramaturgical approach, comparing social life to a theatrical performance in which individuals manage impressions and present different faces in different settings. Unlike structural theories that emphasize large institutions, symbolic interactionism focuses on the small, repeated exchanges through which shared meaning is negotiated, arguing that _______________.

City governments increasingly market dense networks of surveillance cameras as a safety upgrade. Yet the same infrastructure that catches criminals also creates a permanent record of where ordinary citizens go about their daily lives. Once a camera network exists, its purpose can quietly expand, often without new public debate. Civil liberties groups argue that _______________.

John Rawls proposed an unusual thought experiment to determine what principles of justice a society ought to adopt. (A) Imagine a group of rational people gathered to design the basic rules of their future society, but placed behind what he called a veil of ignorance, unaware of their own race, gender, wealth, or social position. (B) Since no one can predict whether they will be born into privilege or poverty, each person has a strong incentive to choose rules that protect the worst-off members of society. (C) Rawls argued that rational people placed in this position would favor arrangements that guarantee basic liberties for everyone and permit unequal outcomes only when they benefit the least advantaged.

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

Critics note a further irony: when something goes wrong, such as a hacked exchange or a lost password, there is often no institution left to appeal to. Blockchain technology was originally promoted as a way to remove the need for trusted middlemen, allowing strangers to exchange value directly and verify transactions through a shared, tamper-resistant ledger. ( ① ) In theory, this design distributes power away from any single institution and toward the network as a whole. ( ② ) In practice, however, a small number of large players have come to dominate many blockchain networks. ( ③ ) They control enough computing power or currency to influence outcomes that were supposed to be decided collectively. ( ④ ) Whether decentralization can survive this concentration of power remains one of the technology's most unresolved questions. ( ⑤ )
