Every July, our school library ①launches a summer reading challenge that invites students to read at least five books before classes begin again in September. Students who ②complete the challenge receive a small prize, but many say the real reward is something else entirely. Without daily homework and tests to worry about, summer gives students rare freedom ③to choose books purely because they sound interesting, not because a teacher assigned them. Librarians notice that students often pick more unusual genres during the challenge, ④including graphic novels, poetry, and nonfiction about hobbies they enjoy. This freedom seems to matter more than the prize itself, since students who only cared about winning tend to quit once the reading feels difficult, while curious readers ⑤keeps going.

Stairs seem too ①ordinary to be dangerous, which is why many people treat them carelessly, texting, carrying an armful of books, or skipping two steps at a time. Emergency room records tell a ②different story: falls on stairways send more people to the hospital each year than almost any other household accident. Familiarity ③discourages a kind of autopilot mode, in which a person stops looking at each step and instead relies on memory of where the stairs should be, a habit that fails the moment something ④unexpected occurs, such as a missing step or a loose railing. Safety officials recommend a few ⑤unglamorous habits: keep one hand free, use the handrail, and turn on the light before stepping onto a dark staircase.

Riding a bicycle is one of the most ①popular ways for teenagers to get around, yet many students still skip the one piece of equipment that could save their life: the helmet. Some argue that a short trip to a nearby store does not require any special protection, since the risk of a serious accident feels ②distant and unlikely. However, most bicycle accidents happen close to home, on familiar streets where riders feel too comfortable to expect danger. A sudden pothole, a car door opening without warning, or a patch of gravel can throw even an experienced cyclist off balance in an ③instant. Wearing a helmet does not prevent a fall, but it dramatically ④increases the chance of a serious head injury when one occurs. For this reason, safety experts insist that a helmet should be treated not as an optional accessory, but as a ⑤basic requirement every time wheels touch the pavement.

Last Saturday, the temperature outside reached almost thirty-eight degrees, so my family decided to stay indoors for the entire day. At first, I worried that staying inside would be boring, but we found several fun activities to enjoy together, which proved that ___________. By the time we got home, I realized that indoor activities could be just as exciting as outdoor ones, especially during a heatwave.

Physical education class often feels like the one period of the day when students can finally move freely, which sometimes leads them to skip the warm-up routine that teachers insist on before any real activity begins. Cold muscles, however, are noticeably less flexible than warmed ones, and _______________. Coaches often compare an unwarmed muscle to a cold rubber band that snaps rather than stretches under sudden pressure.

Sleep debt refers to the cumulative gap between the amount of sleep a person needs and the amount they actually get. (A) Unlike a financial debt, however, this deficit cannot simply be repaid with a single long weekend of rest. (B) When someone loses two hours of sleep every night for a week, the body does not treat the shortage as fourteen separate small losses; instead, it accumulates the deficit, and the resulting impairment in attention and mood can resemble that of a person who has been awake for an entire night. (C) Researchers have found that even modest, chronic sleep restriction gradually impairs reaction time and decision-making, often without the affected person noticing the decline. This is because subjective feelings of tiredness tend to plateau after a few days, even as objective performance keeps deteriorating. Consequently, people frequently underestimate how much sleep debt they are carrying until a demanding task suddenly exposes the accumulated cost.

When people are asked to judge how risky or beneficial a particular technology is, they rarely conduct anything resembling a careful cost-benefit analysis. (A) This mental shortcut, known as the affect heuristic, produces a curious pattern that traditional risk theory struggles to explain: activities people like tend to be judged as both safer and more beneficial, while activities they dislike are judged as both riskier and less beneficial, even when no logical relationship between risk and benefit exists. (B) Instead, they consult a quick emotional impression, an instinctive sense of whether the technology feels good or feels bad, and let that impression guide their entire judgment. (C) For example, when researchers presented a fictional industrial chemical alongside a brief description emphasizing its convenience, participants rated it not only as more useful but also, illogically, as less dangerous. Because emotional impressions form so rapidly and feel so trustworthy, correcting for this heuristic requires deliberate effort; simply presenting more accurate statistics to already anxious or enthusiastic audiences rarely changes their underlying judgment.

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.

When people face a difficult decision, they often weigh not only the expected outcome of each option but also how painful it would feel to discover later that a different choice had been better. (A) Researchers have found that people feel sharper regret over losses that resulted from taking action than over identical losses that resulted from doing nothing. (B) Investors, for example, sometimes continue holding a declining stock rather than selling it, because selling would force them to confront the possibility of having made a clear mistake. (C) This helps explain why so many individuals default to inaction whenever a decision feels uncertain, even when remaining passive is not actually the safer choice.

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
