For most of last year, Junho ①refresh his social media feed constantly, terrified of missing a party, a trending meme, or gossip among his friends. This restless anxiety, ②often called FOMO, or the fear of missing out, left him exhausted and strangely unsatisfied even after hours of scrolling. One weekend, his phone battery died during a hiking trip, and, to his surprise, he actually ③enjoyed the quiet afternoon without notifications interrupting his thoughts. Curious about this unexpected calm, Junho began ④deleting social apps for a few hours each day, gradually extending the breaks as weeks passed. Instead of dreading what he might be missing, he started noticing small pleasures, such as finishing a book or ⑤having an uninterrupted conversation with his family.

Ambitious young athletes and the parents who support them sometimes ①assumes that more training automatically produces better results, a belief that occasionally leads to a condition known as overtraining syndrome. Unlike ordinary fatigue that resolves after a few days of rest, overtraining syndrome develops gradually over weeks or months of insufficient recovery relative to training load, eventually ②producing persistent exhaustion, declining performance despite continued hard work, and increased susceptibility to illness and injury. Adolescents may be especially vulnerable, since their bodies are simultaneously ③coping with the physical demands of growth and the added stress of intensive training schedules. Warning signs are often subtle at first, including disrupted sleep, irritability, and a loss of enthusiasm for a sport the athlete once genuinely enjoyed, which adults often ④mistake for ordinary moodiness. Recovery from full-blown overtraining syndrome can take months rather than days, which is why sports medicine specialists now emphasize ⑤monitoring early warning signs and scheduling rest before symptoms worsen.

One common method, known as social proof, shows images of many people using or enjoying a product, suggesting that its ①popularity guarantees quality. Another technique appeals to authority, featuring experts or professionals endorsing a product to make it seem more ②credible and trustworthy. Repetition also plays a significant role, since seeing the same advertisement multiple times ③decreases familiarity, which people often mistake for reliability. Researchers studying consumer behavior have found that viewers who understand these techniques are less easily ④influenced by them, since awareness disrupts the automatic psychological response advertisers depend on. For this reason, media literacy programs increasingly teach students to ⑤recognize persuasive techniques hidden within everyday advertisements.

When Minji was in ninth grade, she posted a joking comment ①praising a classmate's photo, never imagining anyone would remember it later. During the interview, however, one teacher mentioned having seen an old, ②unkind comment under Minji's name while reviewing applicants' profiles. ③Startled, Minji realized that everything she had ever posted online had quietly accumulated into what is called a digital footprint. Although she ④deleted the comment immediately, the damage to her reputation had already been done. She understood that digital footprints rarely disappear completely, because screenshots and memories often ⑤outlast the content itself.

When people discuss climate change, they often focus only on rising temperatures or melting ice, treating it as a purely scientific issue. However, the concept of climate justice reminds us that _______________. Wealthy, industrialized nations have historically released the largest share of greenhouse gases while building their economies, yet developing nations, which contributed comparatively little, frequently suffer the most severe droughts and floods. This gap between responsibility and suffering raises a serious ethical question that science alone cannot answer. For example, a farming community in a low-income country may lose its entire harvest to an unusual flood, even though its members have never owned a car or flown on a plane. Therefore, tackling climate change requires more than new technology; it demands fair policies supporting the very communities least responsible for causing the crisis.

Travelers who cross several time zones in a single flight often arrive feeling exhausted, foggy, and strangely out of sync with the local clock, a condition widely known as jet lag. The discomfort arises because the body's internal clock continues to run on the schedule of the departure city even after landing. Realigning this internal clock to a new time zone is not instantaneous; researchers estimate that the body typically needs about one day to adjust for every time zone crossed. Flying eastward tends to produce more severe symptoms than flying westward, because _______________. Exposure to natural light at the right moments after arrival can help speed up the adjustment, since light is the strongest external cue the internal clock uses to reset itself.

An echo chamber refers to an online environment where people are mainly exposed to opinions that already match their own beliefs. This phenomenon occurs because social media algorithms tend to recommend content similar to what users have previously liked or shared, gradually narrowing the range of perspectives they encounter. As a result, individuals inside an echo chamber rarely engage with viewpoints that challenge their existing assumptions, which allows their original beliefs to grow increasingly extreme over time. For example, someone who frequently reads articles supporting one political party may begin to see the opposing party as entirely unreasonable, having never seriously considered its arguments. Political polarization, a significant issue in many countries today, is often linked to this pattern of selective exposure. Breaking out of an echo chamber requires ___________.

Soojin started posting short cooking videos on her phone during her last year of high school, never imagining it could become a career. At first, only a handful of friends watched her clips, and she nearly quit after several months without noticeable growth. Still, she quickly learned that being a creator demanded constant work, since algorithms rewarded frequent uploads and audiences expected fresh content daily. Looking back, Soojin realizes that ___________.

That two- or three-hour gap may look modest on paper, but its effects accumulate quickly, touching everything from mood to memory. Across the world, teenagers are chronically short on sleep, often getting two or three hours less than the eight to ten hours experts recommend for their age. ( ① ) Part of the problem lies in biology: as puberty begins, the body's internal clock naturally shifts later, making it difficult for teenagers to fall asleep before eleven at night. ( ② ) Yet school start times rarely adjust to this shift, forcing students to wake before their bodies are ready. ( ③ ) The consequences extend well beyond simple tiredness. Chronic sleep loss during adolescence has been linked to impaired concentration, weakened memory, and a higher risk of anxiety and depression. ( ④ ) It can also disrupt the hormones that regulate appetite, contributing to unhealthy weight gain over time. Some school districts have experimented with delaying start times by even thirty minutes, and early results suggest that students who gain that extra rest show improved grades, better mood, and fewer tardy arrivals. ( ⑤ ) Despite this evidence, changing entrenched school schedules remains a slow and contentious process.

Whenever a user marks a message as spam or rescues a message mistakenly filtered out, that action becomes new training data, sharpening the filter's future decisions. Every day, email providers quietly block billions of unwanted messages before they ever reach a user's inbox, a task that would be impossible without an AI filtering system running constantly in the background. ( ① ) The filter examines each incoming message for suspicious patterns, including certain keywords, unusual sender addresses, and formatting tricks that scammers commonly rely on to slip past detection. ( ② ) What makes the system effective is that it keeps learning after launch. ( ③ ) This creates a constant back-and-forth, since spammers study which messages get blocked and then adjust their wording to slip through again. ( ④ ) As a result, spam filtering is less like a fixed wall and more like an ongoing contest, with each side continuously adapting to outsmart the other. ( ⑤ )
