Last spring, a small cosmetics brand opened a pop-up store in a busy shopping district for just two weeks. Rather than displaying products in the usual manner, the team ①designed the space to resemble a colorful garden, inviting visitors to explore and take photographs. Word spread quickly through social media as customers ②shared images of the unusual setting with their friends and followers. Curious about this success, a marketing researcher later interviewed several visitors, ③who explained that the temporary nature of the event made the experience feel special. Many admitted they had never previously purchased from the brand but ④decided to buy something simply to remember the visit. When the two weeks ended, the brand reported a significant increase in both sales and social media ⑤follower.

For decades, athletes were taught to stretch a muscle and hold the position before any competition, ① believing that this practice alone would prevent injury. Recent research, however, has complicated that assumption considerably. Static stretching, in which a muscle ② is held at its longest length for an extended period, can actually reduce the muscle's ability to generate explosive force immediately afterward. Dynamic stretching, which involves controlled, repeated movement through a joint's full range of motion, ③ appears to prepare muscles for activity without this temporary weakening effect. As a result, many coaches now recommend ④ to save static stretching for after a workout, when it may help restore muscle length and reduce soreness, while ⑤ reserving dynamic movements for the warm-up period before intense effort begins.

A short nap taken in the early afternoon, often called a power nap, can noticeably sharpen attention and mood without ① leaving a person groggy afterward. The key lies in timing: naps limited to roughly twenty minutes allow the brain ② to pass through the lightest stages of sleep while avoiding the deeper stages associated with slow-wave activity. If a nap extends much beyond that window, the sleeper risks ③ waking during deep sleep, which produces a foggy, disoriented feeling known as sleep inertia that can persist for thirty minutes or more. Laboratory studies ④ comparing napping and non-napping groups have repeatedly shown that a brief nap improves reaction time and short-term memory almost as effectively as a full night of extra rest. Interestingly, the benefit appears strongest when the nap occurs several hours after waking, since this is when the body's natural dip in alertness makes rest most ⑤ effectively.

Psychologist Roy Baumeister proposed a concept called ego depletion theory, which suggests that ___________. 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. As this resource becomes depleted throughout the day, later decisions require more effort and are more likely to fail. 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. Some researchers argue that short breaks, adequate sleep, and blood sugar levels can help restore this depleted resource. 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.

Time blocking is a time-management technique in which a person divides the day into fixed blocks. ___________. Instead of relying on a loose to-do list, the person decides exactly when each task will start and end. This approach lowers the mental effort of deciding what to do next, since the schedule already provides the answer. It also limits multitasking, because each block is reserved for only one activity at a time. For instance, a student may block ninety minutes for math practice, leaving no room for messages or web browsing. Another student may reserve an evening block solely for vocabulary review, treating that time like a fixed appointment. Because each block has a clear boundary, unfinished work is less likely to quietly spread into the next task. Many people who adopt time blocking feel more organized throughout the day.

Melatonin is a hormone produced by a small gland deep within the brain, and its release follows a remarkably predictable daily pattern. Levels stay low throughout the bright hours of the day, begin rising in the evening as darkness falls, peak in the middle of the night, and then decline again as morning approaches. This rhythm is controlled primarily by light: specialized cells in the eye detect brightness and send signals that either permit or suppress melatonin production, which is why exposure to bright screens late at night can delay its release and make falling asleep more difficult. Unlike some hormones that directly cause the body to perform a task, _______________, preparing various systems to shift into a lower-energy state. Because of this signaling role, taking melatonin supplements at the wrong time can shift a person's internal clock in the opposite direction from what was intended.

Smartphones, tablets, and computer screens all emit a significant amount of blue light, a short-wavelength light that our eyes are especially sensitive to. During the day, exposure to blue light from the sun helps keep us alert and mentally sharp, which is generally beneficial. At night, however, the same wavelength can interfere with the body's natural preparation for sleep. Specialized cells in the retina detect blue light and send signals to the brain's internal clock, which results in _______________. Studies have found that people who scroll through their phones in bed before sleeping take longer to fall asleep and experience lighter, more easily disrupted sleep than those who avoid screens. Some devices now offer a night mode that shifts the display toward warmer tones, reducing blue light output in the evening. While this feature may help slightly, sleep researchers generally recommend limiting screen use altogether in the hour before bedtime for the best results.

As artificial intelligence grows more capable of performing tasks once considered exclusively human, many people wonder which skills will remain valuable in the future. However, most researchers argue that AI still struggles with tasks requiring genuine empathy, ethical judgment, and creative problem-solving in unfamiliar situations. Similarly, AI can generate countless design variations, yet it lacks the lived experience that allows humans to judge which idea truly resonates with people. For this reason, educators increasingly emphasize skills such as collaboration, critical thinking, and emotional intelligence, arguing that ___________.

Sleep debt refers to the cumulative gap between the amount of sleep a person needs and the amount they actually get. (A) Unlike a financial debt, however, this deficit cannot simply be repaid with a single long weekend of rest. (B) When someone loses two hours of sleep every night for a week, the body does not treat the shortage as fourteen separate small losses; instead, it accumulates the deficit, and the resulting impairment in attention and mood can resemble that of a person who has been awake for an entire night. (C) Researchers have found that even modest, chronic sleep restriction gradually impairs reaction time and decision-making, often without the affected person noticing the decline. This is because subjective feelings of tiredness tend to plateau after a few days, even as objective performance keeps deteriorating. Consequently, people frequently underestimate how much sleep debt they are carrying until a demanding task suddenly exposes the accumulated cost.

주어진 문장: The sudden attention was overwhelming, but it also opened doors she had never imagined. Soojin started posting short cooking videos on her phone during her last year of high school, never imagining it could become a career. ( ① ) At first, only a handful of friends watched her clips, and she nearly quit after several months without noticeable growth. ( ② ) She kept experimenting, however, adjusting her editing style and posting more consistently despite the discouraging numbers. Everything changed when one video demonstrating a simple recipe unexpectedly reached millions of viewers overnight. ( ③ ) Brands began contacting her, offering payment in exchange for featuring their products in future videos. ( ④ ) Within a year, Soojin was earning more from her online content than most entry-level jobs would have paid her. ( ⑤ ) Still, she quickly learned that being a creator demanded constant work, since algorithms rewarded frequent uploads and audiences expected fresh content daily.
