Mira had lived in a coastal village since birth, ①watching the tide creep closer to her family's doorstep every year. When the sea finally swallowed the rice paddies that ②had 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 ③calls climate migrants, people forced to abandon their homes because of rising seas, droughts, or other disasters. This term, rarely used a decade ago, has become increasingly common as extreme weather ④displaces 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 ⑤to protect people like her, since climate migrants are not officially recognized as refugees under current law.

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.

After a viewer finishes an episode, a streaming service rarely leaves the choice of what to watch next entirely up to chance. Instead, a recommendation algorithm ①compares that viewer's habits with patterns drawn from millions of other users who watched similar content, then ranks thousands of titles in order of predicted interest. This approach keeps viewers ②disengaged far longer than a simple list of new releases ever could, which is precisely why streaming companies invest so heavily in refining it. The system is not without drawbacks, however. Because the algorithm favors titles similar to what a viewer already enjoys, it can quietly ③narrow someone's exposure to unfamiliar genres, directors, or cultures, creating a comfortable but repetitive bubble. Some platforms have begun inserting occasional wildcard suggestions, deliberately unrelated to past viewing habits, in an attempt to ④counteract this narrowing effect and keep recommendations from becoming too ⑤predictable.

Time-management researchers frequently mention a principle known as Parkinson's Law, which states that ___________. According to this idea, a task that could be finished in one hour will often stretch to fill an entire afternoon if that much time is scheduled for it. Students who set vague deadlines frequently experience this effect, spending extra hours refining a report that was already complete. Employees given a full week for a simple project may also delay meaningful progress until the final days, even though the actual work requires far less effort. This pattern happens partly because people unconsciously adjust their pace to match perceived urgency. Setting shorter, more specific deadlines can counter this tendency, forcing tasks to fit within a tighter and more realistic window. By recognizing how flexible time encourages unnecessary delay, individuals can complete assignments more efficiently without sacrificing quality.

Scarcity has long been recognized as one of the most effective psychological triggers in marketing. (A) For this reason, limited releases often create long lines and instant sellouts, even when the product itself is not extraordinary. (B) Consumers, fearing that they might miss a rare opportunity, tend to make quick decisions without much thought. (C) Yet this excitement can fade quickly once the item is finally obtained, leaving buyers with regret rather than satisfaction.

A growing number of health apps now track steps, sleep, and heart rate throughout the day, quietly building a detailed picture of a user's physical condition without requiring a single visit to a doctor's office. (A) Doctors caution, however, that these apps are designed to detect patterns, not to diagnose illness, and that a worried user should always confirm any alarming reading with a professional. (B) For people living far from specialists or unable to afford frequent checkups, this kind of constant monitoring can feel like a genuine safety net. (C) By comparing this stream of data against patterns drawn from millions of other users, the app's algorithm can flag early warning signs, such as an irregular heartbeat, long before the person notices anything unusual.

This is precisely the kind of disruption that white noise is designed to prevent. Many people struggling to fall asleep in noisy environments turn to white noise machines, devices that emit a steady, uniform sound covering a broad range of frequencies. ( ① ) The appeal lies in a phenomenon called auditory masking, in which a constant background sound makes sudden noises, such as a slamming door, less noticeable to the sleeping brain. ( ② ) Without this masking effect, an abrupt change in sound is far more likely to trigger a brief awakening, even if the sleeper does not consciously remember it the next morning. ( ③ ) Studies comparing sleep in quiet rooms with sleep alongside white noise have found that participants using white noise experienced fewer of these brief awakenings and reported feeling more rested. ( ④ ) However, researchers caution that the benefit depends heavily on volume and consistency, since noise that is too loud or that varies unpredictably can itself become a source of disruption rather than a remedy. ( ⑤ ) Such backfiring effects remind us that more sound is not always better for a restless sleeper.

Because this feedback loop relies entirely on light rather than on the clock on the wall, melatonin release can shift dramatically when a person travels across time zones or works through the night. Melatonin is a hormone produced by a small gland deep within the brain, and its release follows a remarkably predictable daily pattern. ( ① ) 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. ( ② ) 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. ( ③ ) 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. ( ④ ) 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. ( ⑤ )

주어진 문장: Unlike a rigid vegan diet, this approach does not require anyone to give up their favorite dishes completely. A flexitarian is someone who mainly eats plant-based meals but occasionally includes meat or fish, unlike a strict vegetarian who avoids animal products entirely. ( ① ) This flexible diet has recently gained attention as a practical way to fight climate change, since raising livestock produces a significant portion of global greenhouse gas emissions. ( ② ) Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at trapping heat in the atmosphere. ( ③ ) By replacing just a few meat-based meals each week with vegetables, grains, or legumes, individuals can noticeably shrink their carbon footprint without giving up meat completely. ( ④ ) Nutritionists also emphasize that flexitarian eating is easier to maintain than full vegetarianism, because it allows flexibility rather than demanding absolute discipline. ( ⑤ ) Therefore, many environmental groups now promote flexitarianism as a realistic first step, believing that gradual change, rather than sudden restriction, is more likely to spread widely across society.

주어진 문장: In fields ranging from medicine to law, these tools now perform tasks that once required years of human training. As artificial intelligence grows more capable of performing tasks once considered exclusively human, many people wonder which skills will remain valuable in the future. ( ① ) AI can now analyze data, generate text, and even diagnose certain medical conditions with impressive accuracy. ( ② ) However, most researchers argue that AI still struggles with tasks requiring genuine empathy, ethical judgment, and creative problem-solving in unfamiliar situations. ( ③ ) A machine can recommend a treatment plan based on statistics, for instance, but it cannot comfort a frightened patient the way a compassionate nurse can. ( ④ ) Similarly, AI can generate countless design variations, yet it lacks the lived experience that allows humans to judge which idea truly resonates with people. ( ⑤ ) For this reason, educators increasingly emphasize skills such as collaboration, critical thinking, and emotional intelligence.
