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.

Fast fashion refers to ①cheap, trendy clothing produced quickly and replaced almost as fast as it is bought. Because these garments are designed to be worn only a few times, huge amounts of fabric end up in landfills every year, and the dyeing process ②pollutes rivers near factories. In contrast, a ③growing number of brands are turning toward the circular economy, an economic model in which materials are reused, repaired, or recycled instead of being thrown away after a single use. For example, some companies ④collect old clothes, break down the fibers, and weave them into new fabric, while others let customers rent outfits for special occasions rather than buying garments they will barely wear. These approaches keep resources circulating within the system longer, ⑤increasing demand for raw materials. Therefore, shifting from a throwaway habit toward a circular one may be essential for making the fashion industry sustainable.

Many students ①assume that perfectionists work harder than everyone else, but psychologists describe a puzzling pattern called the perfectionism-procrastination cycle. Because perfectionists set impossibly high standards, they often feel ②anxious before they even begin, and the task feels overwhelming. They then ③accelerate the work to avoid facing their own unrealistic expectations, even though delay only increases their stress later. Likewise, an employee facing an important report may check emails repeatedly rather than begin drafting, fearing an early attempt will seem ④inadequate. Ironically, this avoidance guarantees the very failure that perfectionists dread, since ⑤rushed, last-minute work rarely meets their own high standards.

Until last spring, Minji ①rarely thought twice about tossing a paper cup into the trash after finishing her coffee. Environmental issues seemed ②distant, something scientists and politicians should handle rather than an ordinary student like her. That changed when her class was assigned a documentary about plastic waste drifting through the ocean, footage she initially expected to find boring. Instead, watching seabirds mistake plastic fragments for food left her strangely ③comforted, and she found herself thinking about the assignment long after class ended. The next morning, almost without deciding to, she slipped her old tumbler into her backpack instead of buying a disposable cup on the way to school. It felt like a small, ④meaningless gesture at first. However, as weeks passed, she realized that consistently choosing the tumbler, declining a plastic straw, and reusing a shopping bag were quietly ⑤adding up. Small choices, she discovered, become meaningful once repeated.

Soyeon joined an online study group chat where dozens of students planned a class project together every evening. When one member suggested skipping a required survey step to save time, several others quickly agreed, and no one raised any objections. Soyeon privately worried that skipping the survey might weaken their project, but seeing everyone else nodding along, she stayed silent rather than risk sounding difficult. The group proceeded confidently, convinced their shortcut was harmless, until their teacher pointed out serious gaps once the project was submitted. Afterward, Soyeon learned about groupthink, a concept introduced by psychologist Irving Janis, describing how tightly connected groups often suppress doubts in order to maintain harmony and reach quick agreement. She realized that ___________.

Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. This theory explains that every habit begins with a cue, a signal that tells the brain to start an automatic behavior. The brain then performs a routine, which is the action itself, whether physical or mental. Finally, the brain receives a reward, a positive feeling that makes it want to repeat the same behavior. For example, a notification sound can act as a cue that leads a student to check a phone, and the relief from boredom becomes the reward. Similarly, opening a refrigerator out of habit rather than hunger shows how a routine can run without conscious thought. Because this loop operates automatically, breaking a bad habit requires ___________. Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.

Not all environmental changes happen at the same steady pace. (A) A well-known example involves melting Arctic ice, which exposes darker ocean water that absorbs more sunlight and speeds up further melting in a self-reinforcing cycle. (B) Once this kind of threshold is crossed, reversing the damage becomes extremely difficult, which is why scientists consider identifying these points an urgent priority. (C) Some changes accumulate slowly and predictably, while others can suddenly accelerate once a critical threshold, known as a tipping point, is crossed.

Critics counter that this framing can understate the risk, since even a first draft ultimately shapes everything that follows it. Rather than replacing human creativity outright, many artists, writers, and filmmakers have begun treating AI tools as an unusual kind of collaborator, one that generates dozens of rough options in the time it would take a person to sketch just one. ( ① ) A novelist might ask an AI model for ten possible opening lines and then discard nine, keeping only the phrase that sparks an idea worth developing further. ( ② ) A film composer might use an AI system to generate a rough melody, then rework it entirely by hand until it fits the emotional tone of a specific scene. ( ③ ) What makes this collaboration work, according to many creators, is that the human remains firmly in charge of judgment and taste. ( ④ ) The AI's output, in this view, is treated as raw material rather than a finished product. ( ⑤ )

주어진 문장: This explains why progress often feels rapid and motivating during the earliest days of learning something new. The twenty-hour rule proposes that years of practice are not needed to become skilled at a new activity. ( ① ) Only about twenty hours of effort are needed to reach a useful level. Unlike theories claiming true mastery requires ten thousand hours, this rule targets a more modest goal. That goal is simple competence for everyday use. ( ② ) According to supporters, practicing any new skill produces the fastest visible improvement, since a beginner has room to grow. ( ③ ) Someone learning guitar can typically strum simple chords and follow a basic song within twenty hours of daily practice. ( ④ ) Likewise, a language learner may soon order food or ask directions without years of formal study. ( ⑤ ) Advocates emphasize that the twenty hours must be deliberate and focused, broken into short daily sessions rather than one long stretch. The hours should be aimed at fixing weaknesses rather than repeating what one already knows.

Skipping this final stage, even when an athlete feels fully recovered, dramatically increases the risk of re-injury, because general strength does not automatically translate into the specific coordination that a particular sport demands. Recovering from a serious sports injury involves far more than simply waiting for torn tissue to heal; it requires a carefully structured program that gradually reintroduces stress to the affected area. ( ① ) Immediately after an injury, rest and gentle range-of-motion exercises help prevent stiffness without disturbing the healing tissue. ( ② ) As pain subsides, therapists introduce light resistance training, slowly rebuilding strength in muscles that have weakened from disuse. ( ③ ) Progressing too quickly at this stage is a common mistake, since tissue that appears healed on the surface may still be structurally fragile beneath it. ( ④ ) Only after strength and flexibility approach pre-injury levels do specialists introduce sport-specific drills that mimic the exact movements an athlete will face in competition. ( ⑤ )
