Choice architecture refers to how decisions are ①designed. It determines which option is automatically selected unless a person chooses otherwise, ②known as the default option. Research consistently shows that people tend to stick with whatever is already set, even when changing it takes only seconds. Organ donation is a well-known example. Countries ③which 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 ④automatically 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, so transparency about how defaults are chosen becomes essential, and supporters insist it should be designed ⑤to support people's long-term interests.

Internet activist Eli Pariser introduced the term filter bubble to describe a phenomenon created by online algorithms. Social media platforms and search engines ①constantly track which links users click and how long they linger on certain posts. Based on this data, algorithms ②predict what each individual is most likely to enjoy and quietly prioritize similar content in future results. As a result, two people who type the same search query can receive strikingly different results, each tailored to personal history. This automatic filtering happens ③silently, without users ever deciding to limit what they see. Consequently, many people gradually ④gain access to viewpoints that challenge their existing beliefs, even though they never intended to avoid them. Pariser warned that this invisible curation could weaken democratic debate by narrowing public discussion. Therefore, some experts argue that platforms should reveal how content is filtered, letting users ⑤knowingly escape their own bubbles.

Social psychologists describe a phenomenon called the bystander effect, in which individuals become less likely to help a victim as the number of witnesses ①increases. Each observer assumes someone else will step in, and this diffusion of responsibility leaves no one willing to act. Cyberbullying ②minimizes this problem, since a single humiliating post can be witnessed by thousands of people scattered across the internet rather than a few standing nearby. Anonymity ③intensifies the effect further, allowing silent observers to scroll past cruel comments without feeling accountable for their inaction. Some bystanders even worry that intervening publicly might make them the bully's next target, so they choose to remain ④silent instead. However, silence signals approval to both the bully and the audience watching the exchange unfold. Experts insist that even a single supportive comment can ⑤disrupt this harmful pattern.

When people discuss climate change, they often focus only on rising temperatures or melting ice, treating it as a purely scientific issue. However, the concept of climate justice reminds us that the causes and consequences of climate change are distributed ①**evenly** across the globe. Wealthy, industrialized nations have historically released the ②**largest** share of greenhouse gases while building their economies, yet developing nations, which contributed comparatively little, frequently suffer the most ③**severe** droughts and floods. This gap between responsibility and suffering raises a serious ④**ethical** question that science alone cannot answer. For example, a farming community in a low-income country may lose its entire harvest to an unusual flood, even though its members have never owned a car or flown on a plane. Therefore, tackling climate change requires more than new technology; it demands ⑤**fair** policies supporting the very communities least responsible for causing the crisis.

Behavioral economists use the term status quo bias to describe a tendency to prefer the present situation over a new alternative, even when the alternative would bring greater benefits. This bias helps explain why many households hesitate to switch to renewable energy, such as installing solar panels on their roofs. Although solar panels can lower electricity bills over time, homeowners often stick with their current power source because it feels safe and requires no immediate effort. In contrast, switching demands research, upfront cost, and trust in unfamiliar technology, all of which can seem risky compared with doing nothing. For example, a neighborhood association might repeatedly postpone a vote on shared solar panels, not because the plan is flawed, but because members are reluctant to leave their routine. Therefore, boosting renewable adoption may depend less on proving its advantages and more on _______________.

Across many countries, high schools begin classes early in the morning, often before eight o'clock. (A) Researchers who study this mismatch argue that the underlying problem is not laziness or poor discipline among students, but a scheduling system built around adult rhythms rather than adolescent ones. (B) This schedule assumes that teenagers can simply go to bed earlier to compensate, but biology tells a different story, because the body's internal clock shifts later during adolescence, delaying the release of melatonin until well after ten at night. (C) As a result, most teenagers are not physiologically ready to fall asleep until much later than adults, and when early start times force them to wake before completing a full sleep cycle, the mismatch accumulates into a chronic sleep debt.

Not all parts of a city experience the same temperature, even when they are located close to one another. (A) Tall buildings packed closely together also block wind, trapping warm air within narrow streets. In contrast, areas with abundant trees and open water naturally stay cooler, since plants release moisture that helps lower surrounding temperatures. (B) To reduce this effect, many cities have begun installing rooftop gardens and expanding public parks, hoping that additional greenery will absorb less heat than pavement does. (C) On a summer evening, downtown streets often feel noticeably hotter than nearby parks or suburban neighborhoods, even after the sun has set. This phenomenon, known as the urban heat island effect, occurs when cities retain more heat than surrounding rural areas because of their dense concentration of asphalt, concrete, and buildings. Unlike soil or vegetation, which absorb and release heat gradually, these man-made surfaces absorb sunlight during the day and slowly radiate it back at night, preventing temperatures from cooling.

Sleep hygiene refers to a set of simple daily habits that help the body prepare for consistent, restorative rest. (A) They also advise reserving the bedroom for sleep alone, since using the bed to study, scroll through a phone, or watch videos teaches the brain to associate that space with wakeful activity rather than rest. (B) Physical environment matters as well: a cool, dark, and quiet room tends to produce deeper sleep than one that is warm, bright, or noisy. None of these individual habits guarantees a good night's sleep on its own, but together they form a routine that gradually trains the body to expect and enter sleep more easily, much the way a consistent set of cues trains an athlete's body to perform at a certain time each day. (C) Experts commonly recommend going to bed and waking up at the same time every day, even on weekends, because an irregular schedule confuses the body's internal clock and makes it harder to fall asleep on demand.

A request as ordinary as asking for tomorrow's weather, for instance, triggers a surprisingly long chain of computation behind the scenes. Smart speakers have quietly become a fixture in many households, responding to spoken requests for weather updates, music, or kitchen timers. ( ① ) Behind this simple exchange lies a complex process: the device converts sound waves into text, interprets the meaning using language models, and then generates a spoken reply, all within a second or two. ( ② ) Because these assistants improve by learning from millions of interactions, they gradually become better at recognizing regional accents and casual phrasing that once confused them. ( ③ ) Still, the technology remains far from perfect. ( ④ ) Background noise, overlapping voices, or an unusual sentence structure can cause the assistant to misunderstand a simple request, sometimes with amusing results. ( ⑤ ) Engineers continue to refine these systems, but many admit that truly natural conversation remains one of the hardest goals in the entire field of artificial intelligence.

주어진 문장: She walked into the interview room feeling confident, certain that her past online activity had nothing to do with her qualifications. When Minji was in ninth grade, she posted a joking comment mocking a classmate's photo, never imagining anyone would remember it later. ( ① ) Three years passed, and she nearly forgot the comment existed, buried among hundreds of old posts. ( ② ) Last spring, she applied to join her school's student council, hoping her leadership experience would impress the selection committee. ( ③ ) During the interview, however, one teacher mentioned having seen an old, unkind comment under Minji's name while reviewing applicants' profiles. ( ④ ) Startled, Minji realized that everything she had ever posted online had quietly accumulated into what is called a digital footprint, a lasting trail of personal data left behind by online activity. ( ⑤ ) Although she deleted the comment immediately, the damage to her reputation had already been done. She understood that digital footprints rarely disappear completely, even when the original posts are removed, because screenshots and memories often outlast the content itself.
