In the days leading up to an endurance event, many athletes deliberately increase their carbohydrate intake while reducing training volume, a practice ①known as carbohydrate loading. The strategy ②is design to maximize the amount of glycogen, the storage form of carbohydrate, packed into muscle tissue before competition begins. 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 ③call hitting the wall. Sports nutritionists caution, however, that the timing and composition of meals ④matter as much as the total quantity of carbohydrate consumed, since eating unfamiliar foods immediately before competition can cause digestive discomfort. Athletes are therefore advised ⑤to practice their nutrition strategy during training rather than experimenting with it for the first time on race day.

An echo chamber refers to an online environment where people are mainly exposed to opinions that already ①match their own beliefs. This phenomenon occurs because social media algorithms tend to recommend content similar to what users have previously liked or shared, gradually ②narrowing the range of perspectives they encounter. As a result, individuals inside an echo chamber ③frequently 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 ④unreasonable, having never seriously considered its arguments. Political polarization, a significant issue in many countries today, is often linked to this pattern of ⑤selective exposure.

Last spring, Mina joined the school environmental club because she wanted to make a difference. At first, she felt ①nervous about speaking in front of the other members. However, the club leader, who had been recycling for years, welcomed her ②warmly. Every Friday, the members walked around the school picking up trash near the playground. Mina soon realized that this weekly habit was like watering a small plant every day. For example, a single plastic bottle left outside could take hundreds of years to ③disappear. Therefore, the club decided to place clear recycling bins in every classroom. In contrast to her early doubts, Mina began to feel ④proud of the changes she noticed. Her classmates ⑤stopped separating cans and paper without being reminded by teachers. By the end of the semester, Mina had become an active member.

Sorting your trash correctly is _______________. When you separate paper, plastic, glass, and cans, recycling centers can process each material more efficiently. For example, plastic bottles should be rinsed and have their caps removed before being thrown away. Paper soaked with food or oil, however, cannot be recycled and must go into general waste. Sorting garbage is similar to organizing a closet, where each type of clothing has its own shelf. If items are mixed together carelessly, finding what you need later becomes difficult. Likewise, mixing recyclables with ordinary trash makes the whole recycling process complicated. Many students believe that sorting trash takes too much time, but it actually requires only a few extra seconds. Therefore, learning these basic rules now helps you build a habit that benefits your entire community.

For most of last year, Junho refreshed his social media feed constantly, terrified of missing a party, a trending meme, or gossip among his friends. This restless anxiety, often 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 enjoyed the quiet afternoon without notifications interrupting his thoughts. Curious about this unexpected calm, Junho began deleting 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 having an uninterrupted conversation with his family. This shift in attitude reflects ___________.

Every time a smartphone connects to a network, it records a data point that can later map where its owner has been. The real danger emerges when location data from multiple sources is combined. Companies often argue that anonymized data cannot be traced back to individuals, yet researchers have repeatedly shown that _______________. As a result, privacy experts increasingly insist that location data deserves the same legal protection as medical records.

Scientists have identified certain gene variants that appear more frequently among elite endurance athletes than among the general population, along with a separate set that seems to favor explosive, power-based sports such as sprinting. (A) However, researchers caution strongly against interpreting these findings as evidence that athletic greatness is simply inherited. (B) One frequently studied variant, for instance, influences the proportion of slow-twitch versus fast-twitch muscle fibers a person naturally develops, a ratio that shapes whether a body leans toward endurance or explosive power. (C) Genetics may set a rough ceiling on an individual's ultimate potential, but where any particular athlete lands within that range depends overwhelmingly on training quality, nutrition, coaching, and sheer determination.

The tool draws on enormous amounts of data, including flight prices, seasonal weather patterns, and reviews left by previous travelers, to suggest a route that avoids obvious scheduling conflicts. Planning a multi-city trip once meant hours spent comparing flight schedules, reading hotel reviews, and mapping out which sights were close enough to visit in a single day. ( ① ) AI travel planners now compress much of that work into a short conversation, asking about a budget, a travel style, and a handful of preferences before generating a full day-by-day itinerary within minutes. ( ② ) Many travelers appreciate having a solid starting point rather than a blank page. ( ③ ) Still, seasoned travelers warn that these itineraries can feel oddly generic. ( ④ ) They often steer users toward the same popular landmarks that every other AI-generated plan recommends, while overlooking smaller, lesser-known places that a knowledgeable local guide might have suggested instead. ( ⑤ )

Convenience installed today, in other words, can quietly become control tomorrow. City governments increasingly market dense networks of surveillance cameras as a straightforward safety upgrade, promising faster emergency response and lower crime rates. ( ① ) In many cases, the technology delivers exactly what it promises, helping investigators identify suspects within hours rather than weeks. ( ② ) Yet the same infrastructure that catches criminals also creates a permanent record of where ordinary, law-abiding citizens go about their daily lives. ( ③ ) Once a camera network exists, its purpose can quietly expand, often without new public debate or explicit approval. ( ④ ) Civil liberties groups argue that a city should decide how much surveillance it wants before the cameras go up, not years afterward when the infrastructure is already impossible to remove. ( ⑤ )

At the time, I had no particular career goal in mind. Two years ago, I began volunteering at an animal shelter near my neighborhood on weekends. ( ① ) My tasks included feeding animals, cleaning cages, and helping visitors choose a pet to adopt. ( ② ) Over time, I noticed how much I enjoyed calming nervous or injured animals. ( ③ ) One rainy afternoon, a frightened puppy refused to eat, and I sat quietly beside it for over an hour until it finally relaxed. ( ④ ) I began researching careers in veterinary medicine and animal behavior, subjects I had never seriously considered before. ( ⑤ ) My volunteer work, which started as a simple hobby, slowly turned into the clearest career direction I had ever found.
