문제 1

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.

문제 2

As efforts to curb greenhouse gas emissions intensify, industries unable to eliminate carbon dioxide from their processes have turned to a technology ①known as carbon capture and storage. This technology involves ②separating carbon dioxide from the exhaust of power plants before it is released into the atmosphere, then transporting the captured gas for underground injection. Once injected into porous rock formations, the gas is trapped beneath layers of impermeable rock that ③prevents it from escaping into the air. Proponents argue that carbon capture and storage functions as a bridge technology, allowing heavy industries to keep operating while more sustainable alternatives are developed. For instance, cement and steel production, both of which ④release carbon dioxide as an unavoidable byproduct of chemical reactions, are considered prime candidates for this approach. However, critics contend that the technology remains prohibitively expensive and that building pipelines requires investments few companies make voluntarily. Despite such concerns, many governments continue ⑤funding pilot projects, convinced that this technology will play an indispensable role in reaching emission targets.

문제 3

Millions of people now wear devices that continuously track their heart rate, sleep patterns, and daily activity, ①generating an intimate stream of health data that would have been unthinkable to collect just two decades ago. Users generally assume this information belongs to them, since it ②is drawn directly from their own bodies. In practice, however, the terms of service that few people read often ③grants the manufacturer broad rights to store, analyze, and even sell anonymized versions of that data to insurers or advertisers. This arrangement becomes especially troubling when health data influences decisions far beyond fitness, such as insurance premiums or employment screening. Advocates for reform argue that biological data deserves a category of protection ④stronger than ordinary consumer information, precisely because it can never truly ⑤be replaced or reset once it has been exposed.

문제 4

A small bakery once sold a basic loaf of bread for three dollars and a premium loaf for six dollars, and most customers, ①uncertain about the added value of the pricier option, simply bought the cheaper one. The owner then introduced a third option: a slightly larger premium loaf priced at seven dollars, one that ②were 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 it now ③appeared to be an obvious bargain when placed beside the inferior newcomer. This pattern, ④confirmed across countless pricing experiments in other markets, demonstrates that people rarely judge options in isolation; instead, they evaluate choices relative to whatever alternatives happen to be nearby. Businesses have since learned ⑤to design such decoys deliberately, not expecting them to be purchased at all, but hoping they will make a specific target option look far more attractive by comparison.

문제 5

A printer that once produced only plastic prototypes can now ①deposit living cells layer by layer to build a structure that begins to resemble actual tissue. Bioprinting adapts the logic of conventional 3D printing, ②replacing plastic filament with a specialized ink made of living cells suspended in a gel that supports their survival while the shape sets. Printing a flat patch of skin or a simple blood vessel has already moved from laboratory curiosity to early clinical testing, since these tissues ③is thin enough for nutrients to reach every cell by diffusion. Printing a solid organ such as a kidney remains a far greater challenge, because internal cells starve without their own blood supply, and no printer yet exists that can build a network of vessels fast enough ④to keep them alive. Researchers are therefore focusing on hybrid strategies, printing a rough scaffold and then ⑤allowing the tissue to mature and grow its own vasculature over time.

문제 6

Classical economic theory long assumed that decision makers gather all relevant information, calculate every possible outcome, and select the single option that maximizes their benefit. (A) Herbert Simon, however, questioned this assumption, arguing that human beings operate under real constraints of time, knowledge, and mental capacity that make such exhaustive calculation practically impossible. (B) Instead of searching endlessly for the theoretically perfect choice, people typically stop once they find an option that seems good enough to meet their immediate needs, a strategy Simon termed satisficing. (C) A shopper comparing refrigerators, for example, rarely examines every model available; she instead sets a few practical criteria, such as price and size, and selects the first appliance that satisfies them adequately. This approach is not a failure of reasoning but rather a sensible adaptation to a world where information is costly and time is genuinely limited. Consequently, models assuming unlimited rationality often fail to predict actual behavior, while frameworks acknowledging these cognitive boundaries offer a far more realistic account of how ordinary decisions are actually made.

문제 7

The discovery of CRISPR gene-editing technology gave scientists a tool precise enough to correct a single mistaken letter in the human genome, raising hope for curing inherited diseases. (A) Scientific organizations around the world have therefore drawn a careful line, permitting gene editing to treat disease in existing patients while banning any edit that would be inherited by their descendants. (B) Yet editing a gene in a sperm, egg, or early embryo does not simply change one patient; it alters the genetic code passed down to every future generation. (C) Critics worry, however, that as the technology becomes cheaper and more widely available, this line will become harder to enforce than it is to draw.

문제 8

Suppose a mad scientist removed a living brain from its body and placed it in a vat of nutrient fluid, connecting its neurons to a supercomputer capable of generating perfectly realistic sensations. (A) This scenario, unsettling as it sounds, raises a genuinely difficult question for anyone confident in their own perception: how could a person ever prove that they are not that very brain right now? (B) The brain would experience a full and convincing world, complete with a sky, a body, and other people, without ever suspecting that none of it existed outside the simulation. (C) Ordinary evidence cannot help, since any proof gathered through the senses would itself be generated by the same simulation being tested.

문제 9

For patients born with a single faulty gene, the disease has traditionally been treated indirectly, managing symptoms for a lifetime rather than addressing the genetic error itself. (A) Early trials were haunted by serious setbacks, including cases in which the delivery virus triggered a dangerous immune reaction, but refined delivery methods have since made the treatment considerably safer, leading regulators in several countries to approve gene therapies for a small but growing number of rare inherited disorders. (B) Gene therapy attempts something more ambitious: delivering a corrected copy of the gene directly into a patient's cells, often using a disabled virus stripped of its ability to cause illness as a delivery vehicle. (C) Once inside the nucleus, the corrected gene can begin producing the protein the patient's body had always lacked, in some cases reversing symptoms that medication alone had never been able to touch.

문제 10

Bourdieu argued that habitus allows privilege to reproduce itself across generations without any explicit coercion, since children raised in advantaged households absorb the tastes and manners that institutions such as elite schools implicitly reward, while children from other backgrounds may find the same institutions subtly unfamiliar. French sociologist Pierre Bourdieu introduced the concept of habitus to describe the deeply ingrained dispositions, tastes, and ways of perceiving the world that individuals absorb through years of socialization within a particular social class. ( ① ) Habitus operates below conscious awareness, shaping everything from posture and accent to preferences in food, art, and leisure. ( ② ) A person's habitus feels entirely natural even though it was produced by specific social conditions. ( ③ ) Because habitus feels like personal identity rather than social conditioning, individuals rarely recognize how thoroughly their preferences have been shaped by class position. ( ④ ) This helps explain why social mobility, though officially open to all, remains statistically far more common in theory than in lived practice. ( ⑤ )
