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.

Wearable devices ① that track sleep have become enormously popular, promising a detailed breakdown of light, deep, and REM sleep each night. These gadgets typically rely on movement sensors and heart rate monitors ② to estimate sleep stages, since directly measuring brain activity would require equipment found only in a sleep laboratory. Independent studies ③ compares wearable data with polysomnography, the gold-standard method used in clinical sleep labs, have found that consumer devices are reasonably accurate at distinguishing sleep from wakefulness but considerably less reliable at identifying specific sleep stages. Some trackers overestimate deep sleep, while others ④ underestimate the amount of time spent in REM sleep, and the margin of error can vary widely between brands. Despite these limitations, many users have come ⑤ to treat the nightly score generated by their device as an objective medical verdict, sometimes experiencing anxiety when the number falls below what they expect, a phenomenon researchers have begun calling orthosomnia.

Automation is transforming labor markets more ①quickly than economists predicted a decade ago. Factories once staffed by hundreds of workers now rely on robotic arms that assemble products with remarkable ②precision. This shift does not simply eliminate jobs; it also creates roles that never existed before, so technicians who maintain robotic equipment are now in high ③demand. Companies that invested early in automation often report steady increases in productivity, since machines handle repetitive tasks while employees focus on ④creative problem-solving. Without proper retraining support, the benefits of automation may not be shared fairly, ⑤narrowing inequality between skilled and unskilled labor.

Artificial intelligence has begun to play a surprising role in creative industries once thought to be uniquely human. Some artists ①welcome this technology, using AI tools to explore new styles or overcome creative blocks that once took weeks to resolve. Others, however, argue that AI-generated art ②lacks the emotional depth that comes from genuine human experience. Despite this debate, most experts agree that AI is unlikely to fully ③replace artists anytime soon. Instead, it functions best as a collaborative tool, helping creators experiment ④faster while leaving final artistic decisions to humans. Therefore, artists who learn to work alongside AI may find themselves with a distinct ⑤disadvantage in this rapidly changing industry.

Many people feel a ①sudden wave of anxiety when their smartphone battery is nearly dead or they have left it at home. This ②intense discomfort, known as nomophobia, is short for "no-mobile-phone phobia." Researchers explain that this fear develops because smartphones have become ③tightly linked to social belonging; missing a notification can feel like being cut off from friends. Therefore, experts suggest gradually reducing phone checks to ④strengthen this anxious dependence. Recognizing nomophobia as a real psychological pattern is the first step toward a ⑤healthier relationship with technology.

Many teenagers check their social media accounts dozens of times a day, worried that they might miss something ①important 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 ②loneliness 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 ③deepen feelings of anxiety rather than ④worsen them. Therefore, students should learn to ⑤limit their social media use and focus more attention on the relationships and activities directly in front of them.

Every cell in the human body follows an internal timer known as the circadian rhythm, a roughly twenty-four-hour cycle that governs when we feel alert and when we feel drowsy. This clock is regulated primarily by a tiny cluster of neurons in the brain that responds to light entering through the eyes. When morning sunlight strikes the retina, the cluster signals the body to suppress sleep hormones and raise body temperature, preparing us for activity. As evening approaches and light fades, _______________. Because this rhythm evolved around the natural cycle of day and night, modern habits such as staying indoors under artificial light or working night shifts can push the internal clock out of sync with the external environment. Such misalignment does not simply cause tiredness; it has also been associated with digestive problems and reduced concentration, suggesting that timing matters as much as total sleep hours.

In the days leading up to an endurance event, many athletes deliberately increase their carbohydrate intake while reducing training volume, a practice known as carbohydrate loading. (A) Because glycogen serves as the primary fuel source during prolonged, intense exercise, entering an event with fuller stores can delay the point of exhaustion that runners often call hitting the wall. (B) Sports nutritionists caution, however, that the timing and composition of meals matter as much as the total quantity of carbohydrate consumed. (C) The strategy is designed to maximize the amount of glycogen, the storage form of carbohydrate, packed into muscle tissue before competition begins.

Companies have discovered that ordinary advertisements no longer capture the attention of young consumers as effectively as they once did. (A) As a result, many brands now spend a large portion of their advertising budgets on influencer partnerships rather than television commercials. (B) This is because influencers build long-term relationships with their audiences, which makes recommendations feel personal rather than commercial. (C) However, brands must choose their partners carefully, since an influencer's reputation can directly affect how a product is perceived.

Even small adjustments, such as dimming the lights an hour before bedtime, can make this environment noticeably more sleep-friendly. Sleep hygiene refers to a set of simple daily habits that help the body prepare for consistent, restorative rest. ( ① ) Experts commonly recommend going to bed and waking up at the same time every day, even on weekends, because an irregular schedule confuses the body's internal clock and makes it harder to fall asleep on demand. ( ② ) They also advise reserving the bedroom for sleep alone, since using the bed to study, scroll through a phone, or watch videos teaches the brain to associate that space with wakeful activity rather than rest. ( ③ ) Physical environment matters as well: a cool, dark, and quiet room tends to produce deeper sleep than one that is warm, bright, or noisy. ( ④ ) None of these individual habits guarantees a good night's sleep on its own, but together they form a routine that gradually trains the body to expect and enter sleep more easily, much the way a consistent set of cues trains an athlete's body to perform at a certain time each day.
