Sleep is not a single, uniform state but a cycle that alternates between two very different modes: REM (rapid eye movement) sleep and non-REM sleep. During non-REM sleep, especially its deepest stage, the brain waves slow down dramatically, the body temperature drops, and tissue repair and growth hormone release reach their peak. This is the period ① most closely associated with physical restoration. REM sleep, by contrast, brings rapid eye movements, near-total muscle paralysis, and brain activity that closely ② resemble wakefulness. Most vivid dreaming occurs during this stage, and researchers believe it ③ plays a central role in consolidating memories and processing emotional experiences. A healthy night typically cycles through both stages four or five times, with non-REM ④ dominating the early hours and REM periods lengthening toward morning. Disrupting either stage, through frequent awakenings or alcohol use, can leave a person ⑤ feeling unrested even after a full night in bed.

The gig economy has grown ①rapidly over the past decade, as digital platforms connect customers directly with independent workers. This model offers clear advantages: workers can choose when and how much they work, providing valuable ②rigidity that traditional employment rarely allows. However, gig workers often ③lack benefits such as health insurance and paid leave, which full-time employees typically receive. Because their income can ④fluctuate sharply from month to month, many gig workers struggle to plan their finances confidently. Governments therefore face growing pressure to ⑤protect independent workers through new policies.

Many teenagers check their social media accounts dozens of times a day, worried that they might miss something important happening among their friends. This anxiety, known as FOMO, or the fear of missing out, arises when people believe that others are enjoying experiences from which they themselves are excluded. For example, a student scrolling through photos of a party she was not invited to may suddenly feel a wave of loneliness and regret, even though the event has already ended. Constantly refreshing feeds to avoid missing such updates, however, makes it difficult to concentrate on schoolwork or conversations happening in the present moment. Moreover, this endless comparison with curated highlights of other people's lives tends to deepen feelings of anxiety rather than relieve them. Therefore, students should learn to ___________.

Remote work has moved from a rare privilege to a common practice for millions of employees worldwide. Supporters argue that remote work increases productivity, since employees avoid long commutes and distracting office environments. It also allows companies to hire talented people regardless of where they live, widening the pool of candidates. Critics, however, worry that remote work weakens teamwork and makes it harder for new employees to learn from experienced colleagues. Without regular face-to-face interaction, some workers feel isolated and struggle to build strong professional relationships. For these reasons, many experts suggest that the future of work will likely be ___________, combining flexibility with occasional in-person collaboration.

When the body fights off an infection, the immune system relies heavily on adequate sleep to function effectively. (A) Rather than being a passive state in which the body simply rests, sleep functions as an active period during which the immune system repairs itself and prepares for future threats, which is why doctors often recommend extra sleep when someone is fighting an illness. (B) Chronic sleep deprivation also appears to promote low-grade inflammation throughout the body, a state that has been linked to a higher risk of heart disease and other chronic conditions. (C) During deep sleep, the body produces and releases cytokines, proteins that help regulate immune responses, and people who consistently sleep fewer than six hours a night show measurably weaker antibody responses after vaccination.

For years, a small riverside village had suffered from flooding that grew worse with each passing summer. (A) In addition, several families whose houses stood in the most vulnerable areas relocated to higher ground, and the village installed an early warning system that sent alerts to residents' phones whenever river levels rose dangerously fast. (B) When a powerful storm struck three years later, the new measures proved effective, and the village suffered only minor damage instead of the devastating losses it had previously faced, becoming a model for neighboring communities. (C) Frustrated residents eventually decided to pursue climate adaptation, adjusting their infrastructure and habits to reduce the damage caused by increasingly unpredictable weather, and engineers began by widening the drainage canals surrounding the village so that excess rainwater could flow away more efficiently.

Parkinson's Law appears frequently in everyday workplaces, often without employees even realizing it. (A) As a result, the meeting naturally stretches to fill the entire hour, even though very little new information is actually discussed. (B) This situation illustrates the law's central claim that the amount of time allotted for a task directly shapes how long the task actually takes. (C) Consider a manager who schedules an hour-long meeting to discuss a minor issue that could realistically be resolved in only a few minutes.

주어진 문장: This difference in regulation can create an uneven playing field between the two factories, since one operates under far tighter restrictions than the other. Imagine two factories making the same product: one in a country with strict carbon rules, and one in a country with almost none. ( ① ) The factory facing stricter rules often spends more, which can make its goods pricier than those made elsewhere. ( ② ) To fix this imbalance, some governments have introduced the carbon border adjustment mechanism, a policy charging imported goods a fee based on how much carbon was released while producing them. ( ③ ) Supporters argue that the system protects domestic industries and pushes foreign manufacturers toward cleaner methods. ( ④ ) However, critics claim it unfairly burdens developing countries, which often lack money to modernize factories quickly. ( ⑤ ) For example, a small exporter in a poorer nation might struggle to pay the added charge, though it contributes little to global emissions. Still, if wealthier nations pair the policy with technical support, it could become a genuinely fair tool for cutting emissions worldwide.

주어진 문장: This gap between expectation and reality is not caused by laziness, but by a predictable pattern in how people think about the future. The planning fallacy describes the tendency to underestimate how long a task will take, even when experience suggests otherwise. ( ① ) Psychologists who studied this bias found that people focus mainly on an idealized, best-case version of a project. They focus less on how similar projects actually unfolded before. ( ② ) A student who insists an essay takes two hours, despite needing five hours for every previous essay, shows a clear instance of the fallacy. ( ③ ) Large construction projects offer another example. Officials frequently predict completion dates that later prove far too optimistic once delays appear. ( ④ ) One reason this bias persists is that people rarely review their history of missed deadlines, relying instead on hopeful imagination. ( ⑤ ) Some researchers recommend a technique called reference class forecasting, comparing a new task to similar completed tasks. By anchoring predictions to real outcomes, planners can produce estimates that are considerably more accurate.

Shoppers use it to find where an item seen on the street can be purchased, while students use it to identify plants, insects, or historical artworks in seconds. Instead of typing keywords into a search bar, a growing number of people now simply upload a photo and let an algorithm figure out what it contains. ( ① ) This process, known as reverse image search, compares the visual patterns in a picture against a massive database, identifying everything from a landmark in the background to the exact model of a pair of sneakers. ( ② ) The system works by breaking an image down into countless small features, such as edges, colors, and shapes, then matching that pattern against millions of stored examples. ( ③ ) It is not flawless, however. ( ④ ) A blurry photo, an unusual camera angle, or an object partly hidden behind another can easily confuse the algorithm, leading to search results that have nothing to do with the original picture at all. ( ⑤ )
