For centuries, dreams have fascinated scientists and philosophers alike, yet no single theory fully ①explains why the sleeping brain generates such vivid and often bizarre experiences. One prominent idea suggests that dreaming helps the brain process emotional experiences, ②replays difficult events in a safe, low-stakes environment so that their emotional intensity gradually fades. Another theory proposes that dreams serve a more practical function, ③allowing the brain to rehearse responses to threats without any real danger. Still other researchers argue that dreaming is simply a byproduct of the brain organizing memories, with vivid imagery ④arising as the mind sorts through the day's information rather than serving any independent purpose of its own. Because these theories rest on indirect evidence, none has ⑤been conclusively proven.

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.

Coaches have traditionally focused athlete preparation on training volume and nutrition, but a growing body of research suggests that sleep deserves ①equal attention. During deep sleep, the body releases growth hormone, a substance essential for repairing muscle tissue damaged during intense training, while the brain ②consolidates motor skills practiced earlier that day into more stable, efficient patterns. Athletes who sleep fewer than seven hours a night have been shown to suffer ③more injuries, slower reaction times, and reduced accuracy compared to well-rested peers performing the identical drills. Frequent travel across time zones ④simplifies this challenge considerably, since jet lag can disrupt an athlete's natural sleep-wake cycle for several days after a long flight, sometimes right before an important competition. In response, many professional teams now employ sleep specialists who design travel schedules, control bedroom lighting and temperature, treating sleep as an ⑤active and measurable component of overall athletic training.

Years ago, a small shoe company struggled to compete with larger, well-funded rivals in the market. Its products were ①solid, but customers rarely ②remembered the brand after a single purchase. Sales slowly ③decreased as people felt they were supporting something meaningful rather than simply buying a product. Other companies noticed this shift and began crafting their own narratives, hoping to create similar ④emotional connections. Eventually, the founder realized that a compelling story, told honestly, could turn ordinary customers into ⑤loyal supporters.

For decades, productivity advice has focused almost entirely on managing time efficiently, yet many experts now argue this approach overlooks something important. This alternative approach, known as energy management, suggests that ___________. Unlike time, which flows at a constant rate, human energy naturally rises and falls in cycles shaped by sleep, food, and mental fatigue. A person who tackles difficult tasks during a low-energy period, for instance, may need two hours to finish what takes thirty minutes at peak energy.

After a strenuous workout, muscle fibers experience thousands of microscopic tears, and the body immediately begins a repair process that depends heavily on amino acids, the building blocks that protein supplies. This is why sports scientists recommend consuming protein within a couple of hours after training, since _______________. Many athletes assume that eating an enormous quantity of protein in a single sitting will speed up this process, but the body can only use a limited amount at once; the rest is simply burned for energy or stored as fat.

FOMO refers to the anxious feeling that arises when people believe they are missing out on rewarding experiences that others are having. (A) For instance, a student who sees photos of a gathering she missed may feel sudden regret, even though the event is already over. (B) This feeling often leads people to check their phones compulsively, which makes it hard to focus on tasks at hand. (C) Such experiences are common among heavy social media users, who constantly compare their lives with the curated posts of others.

주어진 문장: Because the number of likes a post will receive is never guaranteed, every notification carries a small element of suspense. Psychologists have long studied a mechanism called the variable reward schedule, in which rewards arrive unpredictably rather than after every single action. ( ① ) Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. ( ② ) When someone posts a photo, they cannot predict exactly when likes will appear, nor how many they will eventually receive. ( ③ ) This uncertainty triggers a small burst of dopamine each time the phone is checked, regardless of whether the result is disappointing or thrilling. ( ④ ) Consequently, users often refresh their feeds compulsively, hoping the next check will finally bring a satisfying reward. ( ⑤ ) What makes this troubling is that technology companies deliberately designed notification systems using insights borrowed from gambling research, rather than stumbling upon them by accident. Such practices raise serious ethical questions about manipulating users' brains for profit. Therefore, people must consciously recognize this hidden mechanism and set firm limits on their checking habits.

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

주어진 문장: This is a significant shift from earlier generations, who often stuck with a single trusted brand for years. Generation Z, typically defined as those born between the late 1990s and early 2010s, approaches shopping quite differently from previous generations. ( ① ) Having grown up with smartphones and social media, they research products extensively online before making even small purchases. ( ② ) Unlike older generations, who often valued brand loyalty above all else, many members of Generation Z prioritize a company's values, switching brands easily if one no longer matches their beliefs. ( ③ ) They also tend to favor secondhand and resale platforms, viewing sustainability as an important factor rather than an afterthought. ( ④ ) Peer recommendations shared through short videos frequently carry more weight than traditional celebrity endorsements. ( ⑤ ) Businesses that fail to adapt to these preferences risk losing an entire generation of potential customers.
