Students who read many books across many different subjects often develop a habit ① that quieter learners sometimes lack: the habit of comparing new information with what they already know. A student who has read about ancient wars, ocean ecosystems, and modern economics can more easily notice when two different subjects ② share a similar pattern. This kind of connection-making is closely related to what psychologists call critical thinking, since seeing a familiar pattern in an unfamiliar topic ③ allows a person to ask sharper questions instead of accepting new information at face value. Extensive reading also builds a large mental library of examples, which makes it easier ④ to evaluate whether a new claim sounds reasonable or exaggerated. Teachers often notice that widely read students argue more carefully, ⑤ support their opinions with specific examples rather than vague generalizations.

For most of the twentieth century, a library was simply a quiet room full of books, and visitors were expected ① to stay silent while they searched the shelves. Today, many public libraries look completely different. Alongside the usual shelves, you might find group study rooms, comfortable sofas for reading, computer labs, and even small recording studios for podcasts. Librarians say this change ② did not happen by accident. As more information moved online, fewer people ③ needing a library simply to find facts, so librarians began asking what their communities actually needed instead. The answer, in many neighborhoods, turned out ④ to be space itself: a warm, free place where students could study together, job seekers could print a resume, and children could attend a story hour. Librarians respond that reading and gathering have always belonged together, and that a library survives only by ⑤ changing with its readers.

Cities are frequently several degrees warmer than the surrounding countryside, a phenomenon ①known as the urban heat island effect, which intensifies in summer and threatens public health. This disparity arises largely because asphalt and concrete absorb solar radiation during the day and slowly release it as heat throughout the night, ②preventing urban areas from cooling down. To address this problem, urban planners have begun implementing mitigation strategies ③designed to lower surface and air temperatures. One widely used solution involves reflective "cool" roofing ④engineered to reflect more sunlight than dark rooftops absorb. Another strategy, green infrastructure, incorporates rooftop gardens and tree-lined streets that ⑤provides shade while releasing moisture.

Modern sports wearables, from wrist-worn fitness trackers to smart insoles embedded in running shoes, continuously collect data that would once have required a laboratory to measure. Heart rate, sleep quality, running cadence, and even subtle changes in gait can now be ① monitored during ordinary daily activity rather than only in a controlled clinical setting. Coaches use this constant stream of information to detect early warning signs of overtraining, sometimes noticing a decline in performance ② after the athlete consciously feels tired. However, the flood of data has created a new challenge: distinguishing a meaningful pattern from ordinary daily fluctuation requires expertise that many amateur athletes simply ③ do not have. Some researchers worry that casual users may misinterpret a single unusual reading as a serious problem, leading to ④ needless anxiety rather than useful insight. For this reason, most experts recommend treating wearable data as a general trend to observe over time, not as a precise ⑤ diagnostic tool.

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. Herbert Simon, however, questioned this assumption, arguing that human beings operate under real constraints of time, knowledge, and mental capacity that make such ① exhaustive calculation practically impossible. Instead of searching ② 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. 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 ③ adequately. This approach is not a failure of reasoning but rather a sensible adaptation to a world where information is ④ 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 ⑤ unrealistic account of how ordinary decisions are actually made.

Desalination, the process of removing dissolved salts from seawater to produce fresh water, has increasingly been adopted by coastal regions facing chronic water ①scarcity. Most modern facilities rely on reverse osmosis, a technique in which seawater is forced through membranes whose microscopic pores block salt while letting water molecules pass. Because this method ②consumes far less energy than the thermal distillation once dominant in the industry, it has become the preferred choice for large-scale plants. Nevertheless, desalination remains an inherently costly and environmentally burdensome solution, a fact often overlooked amid enthusiasm for ending water shortages. For instance, the process generates a ③concentrated byproduct called brine, which, when discharged without adequate dilution, can raise local salinity to levels that harm marine life. Pumping seawater through membranes at high pressure also demands substantial electricity, so plants powered by fossil fuels can ④alleviate the emissions that intensify drought. Therefore, engineers increasingly argue that desalination should be treated not as a stand-alone remedy but as one component of a ⑤broader conservation strategy.

Choice architecture refers to how decisions are designed. It determines which option is automatically selected unless a person chooses otherwise, known as the default option. Research consistently shows that ___________, even when changing it takes only seconds. Organ donation is a well-known example. Countries where citizens are automatically registered as donors unless they opt out show much higher donation rates than opt-in countries. Retirement savings programs show a similar pattern, since employees automatically enrolled in a pension plan rarely cancel it. Voluntary sign-ups, in contrast, often delay indefinitely. Critics argue that default options can be manipulated to benefit companies rather than individuals, so transparency about how defaults are chosen becomes essential. Still, supporters insist that because some default must always exist, it should support people's own long-term interests rather than mere institutional convenience.

Role-playing these scenarios in advance helps children respond quickly under pressure, rather than freezing because the situation feels unfamiliar and confusing. Experts also emphasize that _______________, since hesitation caused by politeness can cost precious seconds in a genuine emergency.

Stairs seem too ordinary to be dangerous, which is why many people treat them carelessly, texting, carrying an armful of books, or skipping two steps at a time. (A) Familiarity encourages 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. (B) Safety officials recommend a few unglamorous habits: keep one hand free, use the handrail, and turn on the light before stepping onto a dark staircase. (C) Emergency room records tell a different story: falls on stairways send more people to the hospital each year than almost any other household accident.

**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
