Sleep debt refers to the cumulative gap between the amount of sleep a person needs and the amount they actually get. Unlike a financial debt, however, this deficit cannot simply ①be repaid with a single long weekend of rest. 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 ②who has been awake for an entire night. Researchers have found that even modest, chronic sleep restriction gradually impairs reaction time and decision-making, often without the affected person ③noticing the decline. This is because subjective feelings of tiredness tend to plateau after a few days, even as objective performance keeps ④deteriorate. Consequently, people frequently underestimate how much sleep debt they are carrying until a demanding task suddenly ⑤exposes the accumulated cost.

Jiho had always assumed he would join a large corporation after graduation, just as his parents expected. During his final year of university, however, he joined a small student team ①building an app that connected local farmers directly with restaurants. What started as a class project gradually ②turned into something more serious, as several restaurants began placing regular orders through their prototype. Jiho and his teammates decided ③to delay job applications and instead spend a year developing the idea, despite warnings from relatives ④who considered the plan too risky. After nearly failing twice, the team secured a small investment that allowed them ⑤hire their first employee.

When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers ①belonged only to a handful of government scientists. By the time he entered university, however, the space industry had changed dramatically, as private companies began ②launching satellites and building reusable rockets. Daniel studied aerospace engineering, ③drawing to the idea that space exploration was no longer limited to a few national agencies. During an internship, he helped design a small satellite ④intended to monitor crop health from orbit. He realized that the space industry now needed not only pilots and engineers but also data analysts and technicians ⑤familiar with international space regulations.

Building brand loyalty has traditionally been considered one of the most valuable goals in marketing, since loyal customers ①tend to spend more and recommend products to others. Companies invest significant resources in loyalty programs, ②offering points, discounts, and exclusive access to encourage repeat purchases. Genuine loyalty, critics contend, should be earned through consistent quality and honest treatment of customers, not through artificial incentives that merely ③delays a customer's departure. Furthermore, excessive focus on retaining existing customers can cause companies ④to neglect innovation, since they assume loyal buyers will continue purchasing regardless of improvements. Relying solely on loyalty programs without addressing underlying product quality may ultimately ⑤backfire.

When the body fights off an infection, the immune system relies heavily on adequate sleep to function ①effectively. During deep sleep, the body produces and releases cytokines, proteins that help ②regulate immune responses and coordinate the fight against harmful invaders. People who consistently sleep fewer than six hours a night show measurably ③weaker antibody responses after vaccination compared with those who sleep seven or eight hours. Chronic sleep deprivation also appears to ④reduce low-grade inflammation throughout the body, a state that has been linked to a higher risk of heart disease. Rather than being a passive state, sleep functions as an active period during which the immune system repairs itself and ⑤prepares for future threats.

Caffeine is the most widely consumed stimulant in the world, prized for its ability to sharpen focus and fight off fatigue within minutes of consumption. It works by blocking adenosine, a chemical that gradually builds up in the brain throughout the day and makes us feel increasingly sleepy the longer we stay awake. By occupying the receptors that adenosine would normally bind to, caffeine tricks the brain into feeling alert even when the body has accumulated significant sleep pressure. The effects, however, last far longer than most people realize. Because caffeine can remain active in the bloodstream for five to six hours, a cup of coffee consumed in the late afternoon may still be interfering with the ability to fall asleep at midnight. Even when people do not consciously notice difficulty falling asleep, _______________. For this reason, many sleep specialists advise avoiding caffeine after early afternoon.

A short nap taken in the early afternoon, often called a power nap, can noticeably sharpen attention and mood without leaving a person groggy afterward. The key lies in timing: naps limited to roughly twenty minutes allow the brain 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, _______________. Laboratory studies 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 effective. For this reason, many workplaces now designate quiet rooms where employees can recharge briefly during the day.

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 swallowed 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, _______________. This term, rarely used a decade ago, has become increasingly common 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 struggle to agree on how to protect people like her, since climate migrants are not officially recognized as refugees under current law.

주어진 문장: Yet this strategy of delay backfires, since it leaves no time to revise or correct errors before the deadline. Many students assume that perfectionists work harder than everyone else, but psychologists describe a puzzling pattern called the perfectionism-procrastination cycle. ( ① ) This term describes how an intense fear of imperfect work causes people to delay starting a task rather than begin it. ( ② ) Because perfectionists set impossibly high standards, they often feel anxious before they even begin, and the task feels overwhelming. ( ③ ) They then postpone the work to avoid facing their own unrealistic expectations, even though delay only increases their stress later. ( ④ ) For example, a student writing a research paper might spend hours reorganizing notes instead of composing a single sentence that feels good enough. Likewise, an employee facing an important report may check emails repeatedly rather than begin drafting, fearing an early attempt will seem inadequate. ( ⑤ ) Ironically, this avoidance guarantees the very failure that perfectionists dread, since rushed, last-minute work rarely meets their own high standards.

주어진 문장: Still, the risk of falling behind outweighs the discomfort of constant adjustment, most experts say. As technology continues to reshape nearly every profession, the idea of finishing education after graduation has become outdated. ( ① ) Workers who once expected their initial training to last an entire career now find that skills can become obsolete within just a few years. ( ② ) Lifelong learning, therefore, has shifted from being an optional pursuit to a practical necessity for staying competitive in the job market. ( ③ ) Many professionals now take short online courses, attend workshops, or earn new certifications while continuing to work full-time. ( ④ ) Critics argue that constant learning can be exhausting and difficult to balance with personal responsibilities. ( ⑤ ) In a rapidly changing economy, the ability to learn continuously may matter more than any single degree.
