Many people struggling to fall asleep in noisy environments turn to white noise machines, devices that ①emit a steady, uniform sound covering a broad range of frequencies. The appeal lies in a phenomenon called auditory masking, in which a constant background sound makes sudden noises ②less noticeable to the sleeping brain. Without this masking effect, an abrupt change in sound is far more likely ③to trigger a brief awakening, even if the sleeper does not consciously remember it the next morning. Studies comparing sleep in quiet rooms with sleep alongside white noise have found that participants using white noise ④experienced fewer of these brief awakenings. However, researchers caution that the benefit depends heavily on volume and consistency, since noise that is too loud or that ⑤varying unpredictably can itself become a source of disruption rather than a remedy.

A flexitarian is someone who mainly ①eating plant-based meals but occasionally includes meat or fish, unlike a strict vegetarian who avoids animal products entirely. This flexible diet has recently gained attention as a practical way to fight climate change, since raising livestock ②produces a significant portion of global greenhouse gas emissions. Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at ③trapping heat in the atmosphere. By replacing just a few meat-based meals each week with vegetables, grains, or legumes, individuals can noticeably shrink their carbon footprint without giving up meat completely. Nutritionists also emphasize that flexitarian eating is easier to maintain than full vegetarianism, because it ④allows flexibility rather than demanding absolute discipline. Therefore, many environmental groups now promote flexitarianism as a realistic first step, ⑤believing that gradual change, rather than sudden restriction, is more likely to spread widely across society.

Only a decade ago, translation apps produced sentences so ①awkward that users often laughed at the results rather than trusting them. Today, many of these apps rely on neural networks that analyze entire sentences at once, capturing context instead of translating word by word. This shift has made everyday tasks such as reading a foreign menu or chatting with an overseas friend remarkably ②chaotic. Frequent travelers now point their phone cameras at street signs and receive an ③instant translation overlaid on the screen. Even so, the technology still struggles with humor, sarcasm, and cultural nuance, areas where a single wrong word can ④completely change the intended meaning. For this reason, professional translators argue that these apps are best treated as a helpful ⑤starting point rather than a final, polished result.

Planning a multi-city trip once meant hours spent comparing flight schedules, reading hotel reviews, and mapping out which sights were close enough to visit in a single day. AI travel planners now ①compress much of that work into a short conversation, asking about a budget, a travel style, and a handful of preferences before generating a full day-by-day itinerary within minutes. The tool draws on enormous amounts of data to suggest a route that avoids obvious ②scheduling conflicts. Many travelers appreciate having a solid starting point rather than a ③blank page. Still, seasoned travelers warn that these itineraries can feel oddly ④unique, often steering users toward the same popular landmarks that every other AI-generated plan recommends, while ⑤overlooking smaller, lesser-known places that a knowledgeable local guide might have suggested instead.

Skipping a proper warm-up before intense exercise might seem like a harmless way to save a few minutes, but the practice carries real physiological costs. A cold muscle is ①more flexible and less elastic than a warm one, making it considerably more prone to strains and tears when suddenly asked to contract forcefully. Gradually raising body temperature through light activity ②increases blood flow to the muscles, allowing oxygen to reach tissue more efficiently and enabling nerve signals to travel faster between the brain and the muscle fibers. A proper warm-up also raises heart rate gradually, ③easing the cardiovascular system into strenuous work rather than shocking it with a sudden demand. Athletes who warm up thoroughly tend to report ④better performance in the early minutes of competition, since their bodies are already ⑤primed rather than adjusting on the fly.

Choice architecture refers to how decisions are designed. It determines which option is automatically selected unless a person ①actively chooses otherwise, known 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 where citizens are automatically registered as donors unless they opt out show ②much higher donation rates than opt-in countries. Retirement savings programs show a similar pattern, since employees automatically enrolled in a pension plan ③rarely 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 ④unnecessary. Still, supporters insist that because some default must always exist, it should support people's own long-term interests rather than mere ⑤institutional convenience.

Minji spent nearly every evening watching Jimin, an online creator who streamed cooking videos and chatted casually with her viewers. Over several months, Minji began to feel as though she truly knew Jimin, laughing at her jokes and worrying whenever she mentioned having a difficult week. Whenever Jimin responded to a comment, even a simple one, Minji felt a small thrill of connection, as if they were becoming closer friends. One day, Minji excitedly waited outside a fan event, hoping that Jimin would recognize her from the countless messages she had sent. However, Jimin greeted her the same way she greeted every other stranger in line, without any hint of personal recognition. Standing there, Minji slowly realized that ___________.

Time perception can also shift according to age, not only according to attention or emotion. (A) This may occur because each year represents a smaller fraction of a person's total life as they grow older. (B) Many older adults report that entire years seem to pass more quickly than they did during childhood. (C) Psychologists studying this phenomenon have proposed that our sense of time speed is partly relative rather than fixed.

주어진 문장: This heightened sensitivity can manifest in a variety of noticeable ways. In recent years, mental health experts have identified a distinct emotional response to environmental crisis, commonly called eco-anxiety. ( ① ) Eco-anxiety describes persistent worry, grief, or fear triggered by awareness of climate change and its consequences for the future. ( ② ) Although people of all ages can experience it, teenagers and young adults seem especially vulnerable, since they anticipate living through decades of worsening conditions. ( ③ ) Common symptoms include difficulty sleeping, a sense of hopelessness, and guilt over ordinary choices such as travel or diet. ( ④ ) For example, some students report feeling paralyzed whenever they read alarming climate news, unable to focus on schoolwork or hobbies. ( ⑤ ) 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 encouraged to join community projects, since taking constructive action tends to restore a sense of control and ease overwhelming distress.

주어진 문장: This is why many people find it especially difficult to maintain healthy eating habits after a long, stressful day at work. Psychologist Roy Baumeister proposed a concept called ego depletion theory, which suggests that willpower functions like a muscle that gradually tires after repeated use. ( ① ) According to this theory, every act of self-control, from resisting a snack to concentrating on difficult homework, draws from the same limited mental resource. ( ② ) As this resource becomes depleted throughout the day, later decisions require more effort and are more likely to fail. ( ③ ) For instance, someone who exercises discipline avoiding distractions all morning may struggle to resist checking a phone by evening. Likewise, dieters report that self-control weakens sharply at night, after hours of resisting food. ( ④ ) Some researchers argue that short breaks, adequate sleep, and blood sugar levels can help restore this depleted resource. ( ⑤ ) Although later studies have questioned how strong this effect is, the theory still offers a useful framework for understanding why willpower seems to fade throughout a long day.
