When Mina was a freshman, she often ①spent her allowance within a few days. Her older cousin told her about the marshmallow experiment, a famous study ②in which children could eat one marshmallow immediately or wait for two. Researchers found that children who waited longer ③shown better academic performance and self-control years later. Inspired by the study, Mina began ④saving half of her allowance each week instead of spending it all on snacks. After three months, however, she had saved enough to buy a bicycle she had ⑤wanted for over a year.

Mira had lived in a coastal village since birth, watching the tide creep closer to her family's doorstep every year. When the sea finally ①swallowed the rice paddies that had fed her village for generations, her parents decided that staying was no longer possible. Together with many neighbors, they packed what little they could carry and moved inland, becoming what experts now call climate migrants, people forced to ②abandon their homes because of rising seas, droughts, or other disasters. This term, rarely used a decade ago, has become increasingly ③common as extreme weather displaces communities worldwide. Mira missed her old house terribly, yet she slowly began to build a new life in the crowded city, learning to adapt just as her ancestors once had. International organizations, however, still ④manage to agree on how to protect people like her, since climate migrants are not officially ⑤recognized as refugees under current law.

After an especially demanding training session, the instinct to collapse onto a couch and remain motionless is understandable, yet exercise physiologists increasingly recommend the opposite approach. Active recovery involves performing low-intensity movement, such as a light jog, an easy swim, or a gentle bike ride, on days following intense exertion rather than resting completely, since _______________. Some athletes worry that any movement at all will interfere with the repair process, but research suggests that truly light activity does not meaningfully slow healing and may even reduce the perceived soreness that follows a hard session.

Sociologist Mark Granovetter introduced an idea that seems contradictory at first glance, known as the strength of weak ties. According to this theory, people who see each other only occasionally, called weak ties, often provide more valuable information than close friends or family members, who are considered strong ties. This happens because strong ties tend to share the same social circles and, therefore, already possess similar knowledge. Weak ties, in contrast, move within different networks, which allows them to introduce ideas or opportunities that would otherwise remain unknown. For example, a former classmate rarely contacted might mention a job opening unavailable through one's immediate circle. Social media platforms have made maintaining such connections remarkably easier, letting users keep hundreds of loose acquaintances active without frequent face-to-face meetings. Consequently, these platforms _______________.

Coaches have traditionally focused athlete preparation on training volume and nutrition, but a growing body of research suggests that sleep deserves equal attention. During deep sleep, the body releases growth hormone, a substance essential for repairing muscle tissue damaged during intense training, while the brain consolidates motor skills practiced earlier that day into more stable, efficient patterns. As a result, _______________. Frequent travel across time zones compounds 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.

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.

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.

Melatonin is a hormone produced by a small gland deep within the brain, and its release follows a remarkably predictable daily pattern. (A) 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. (B) 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. (C) Unlike some hormones that directly cause the body to perform a task, melatonin does not force sleep to occur; instead, it signals to the rest of the body that night has arrived, 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.

Jihun wanted to start stretching every day but kept forgetting no matter how many notes he left himself. (A) After a month, he no longer needed to think about it, because the smell of coffee alone reminded him to stretch. (B) He decided to try habit stacking by connecting the new habit to something he already did without fail each morning. (C) Since he never skipped making coffee before school, he began stretching for five minutes while the coffee machine ran.

주어진 문장: Without such structure, even highly motivated students may unconsciously postpone tasks that feel too far removed from the present moment. Behavioral economists use the term temporal discounting to describe how people undervalue future rewards simply because those rewards are not immediate. ( ① ) This tendency explains why a student might choose to watch videos tonight rather than study for an exam that remains several weeks away, even though studying offers a greater long-term benefit. ( ② ) A distant reward, no matter how valuable, feels psychologically smaller than a small reward available right now. This bias contributes to procrastination, since future consequences rarely feel urgent enough to motivate immediate action. ( ③ ) To counter this tendency, students should convert distant goals into smaller, near-term milestones that feel more emotionally real. ( ④ ) Setting weekly checkpoints rather than a final deadline can make future benefits feel closer and more concrete. Teachers and parents should provide immediate, meaningful feedback, since prompt recognition helps bridge the gap between present effort and delayed reward, ultimately reducing the urge to postpone tasks. ( ⑤ )
