Imagine a cafeteria where a healthy salad ①sits at eye level while fried snacks rest on a low shelf. Nobody is ②forbidden from choosing the snacks, yet most people quietly pick the salad instead. This simple technique illustrates a nudge, a concept from behavioral economics that gently ③guides people toward better choices without restricting their freedom. Companies and governments increasingly apply nudges to encourage sustainable consumption. For example, some hotels print reminders on towels stating that most guests reuse them, which ④persuade new guests to do the same and save water. Similarly, energy bills that compare a household's usage with that of efficient neighbors often lead people to reduce electricity use. Unlike strict regulations or heavy taxes, nudges ⑤rely on subtle changes in design rather than force. Critics argue nudges alone cannot solve large environmental problems, but combined with stronger policies, they can meaningfully shift everyday habits toward sustainability.

A navigation app calculating a route rarely relies on distance alone; instead, it constantly weighs real-time traffic reports, past congestion patterns for that time of day, and even data from other drivers' phones ① currently on the road. This flood of information allows the app ② to reroute a driver away from a sudden accident within seconds, often before the driver has any idea the accident ③ occurring at all. The convenience comes at a cost that few passengers consider, however. When thousands of drivers are simultaneously ④ redirected onto the same shortcut, that quiet side street can quickly become as congested as the highway it was meant to help travelers avoid. Residents of these once-quiet neighborhoods have increasingly complained about the sudden surge of unfamiliar traffic, ⑤ arguing that an algorithm optimizing for individual convenience can end up creating a new problem.

Turning on automatic captions used to mean settling for garbled text full of obvious errors, but recent speech-recognition models have made same-language captions ① accurate enough that many viewers now leave them on by default, even when watching content in their native language. The technology listens to audio, breaks it into individual sounds, and matches those sounds against a massive library of words and phrases to predict what was actually said. For viewers who are deaf or hard of hearing, this improvement has quietly ② transformed everyday access to video content that once required a human transcriber and a considerable amount of time to caption properly. The system still ③ excels at overlapping speakers, strong accents, and specialized vocabulary such as medical or technical terms, occasionally producing captions that are unintentionally funny. Even with these ④ flaws, most users agree that imperfect captions are far more ⑤ useful than no captions at all.

In recent years, mental health experts have identified a distinct emotional response to environmental crisis, commonly called eco-anxiety. Eco-anxiety describes persistent worry, grief, or fear triggered by awareness of climate change and its consequences for the future. Although people of all ages can experience it, teenagers and young adults seem especially vulnerable, since they anticipate living through decades of worsening conditions. Common symptoms include difficulty sleeping, a sense of hopelessness, and guilt over ordinary choices such as travel or diet. For example, some students report feeling paralyzed whenever they read alarming climate news, unable to focus on schoolwork or hobbies. However, experts emphasize that eco-anxiety is not a disorder to be eliminated but a natural reaction that can be channeled productively. Rather than avoiding the topic, young people are _______________.

Across the world, teenagers are chronically short on sleep, often getting two or three hours less than the eight to ten hours experts recommend for their age. Part of the problem lies in biology: as puberty begins, _______________. Yet school start times rarely adjust to this shift, forcing students to wake before their bodies are ready. The consequences extend well beyond simple tiredness. Chronic sleep loss during adolescence has been linked to impaired concentration, weakened memory, and a higher risk of anxiety and depression. It can also disrupt the hormones that regulate appetite, contributing to unhealthy weight gain over time. Some school districts have experimented with delaying start times by even thirty minutes, and early results suggest that students who gain that extra rest show improved grades, better mood, and fewer tardy arrivals. Despite this evidence, changing entrenched school schedules remains a slow and contentious process.

Sleep is not a single, uniform state but a cycle that alternates between two very different modes: REM (rapid eye movement) sleep and non-REM sleep. During non-REM sleep, especially its deepest stage, the brain waves slow down dramatically, the body temperature drops, and tissue repair and growth hormone release reach their peak. This is the period most closely associated with physical restoration. REM sleep, by contrast, brings rapid eye movements, near-total muscle paralysis, and brain activity that closely resembles wakefulness. Most vivid dreaming occurs during this stage, and researchers believe _______________. A healthy night typically cycles through both stages four or five times, with non-REM dominating the early hours and REM periods lengthening toward morning. Disrupting either stage, through frequent awakenings or alcohol use, can leave a person feeling unrested even after a full night in bed.

Highlighting an awkward sentence and instantly seeing three smoother alternatives has become a routine part of writing for many students, thanks to AI writing assistants built into word processors and browsers. (A) Concerns grow, however, around the tone and phrasing suggestions, which can gradually nudge every student's writing toward a similar, polished style. (B) Teachers generally welcome the grammar and spelling support, since it frees up class time to focus on argument and structure rather than comma placement. (C) These tools check grammar and spelling, of course, but the more advanced versions go further, suggesting clearer phrasing, flagging repetitive words, and even adjusting tone depending on the purpose.

Only a decade ago, translation apps produced sentences so awkward that users often laughed at the results rather than trusting them. (A) Frequent travelers now point their phone cameras at street signs and receive an instant translation overlaid on the screen, thanks to this leap in accuracy. (B) Even so, the technology still struggles with humor, sarcasm, and cultural nuance, areas where a single wrong word can completely change the intended meaning. (C) Today, many of these apps rely on neural networks that analyze entire sentences at once, capturing context instead of translating word by word.

주어진 문장: After all, ignoring proven facts might seem like an irrational thing to do. When people encounter solid scientific evidence about climate change, we might expect them to accept it without hesitation. ( ① ) However, many individuals still dismiss or downplay such evidence, and psychologists explain this pattern through a concept called motivated reasoning. ( ② ) Motivated reasoning refers to the tendency to process information in a way that protects one's existing beliefs, identity, or lifestyle rather than to pursue objective truth. ( ③ ) For example, a person whose livelihood depends on the fossil fuel industry may unconsciously search for reasons to doubt climate data, even while claiming to value scientific accuracy. ( ④ ) This happens because accepting uncomfortable facts can threaten a person's sense of self or demand costly lifestyle changes. ( ⑤ ) Therefore, simply presenting more data rarely persuades a committed skeptic. Instead, experts suggest connecting climate information to values the person already holds, such as family safety or economic stability, so that acceptance feels natural rather than threatening.

This built-in schedule does not simply respond to the clock on the wall; it is shaped directly by light itself. Every cell in the human body follows an internal timer known as the circadian rhythm, a roughly twenty-four-hour cycle that governs when we feel alert and when we feel drowsy. ( ① ) This clock is regulated primarily by a tiny cluster of neurons in the brain that responds to light entering through the eyes. ( ② ) When morning sunlight strikes the retina, the cluster signals the body to suppress sleep hormones and raise body temperature, preparing us for activity. ( ③ ) As evening approaches and light fades, the same mechanism triggers the release of melatonin, a hormone that promotes drowsiness. ( ④ ) Because this rhythm evolved around the natural cycle of day and night, modern habits such as staying indoors under artificial light or working night shifts can push the internal clock out of sync with the external environment. ( ⑤ ) Such misalignment does not simply cause tiredness; it has also been associated with digestive problems and reduced concentration, suggesting that timing matters as much as total sleep hours.
