Last Saturday, Jimin visited the recycling center near her apartment with her science class. She ①had expected the place to be dirty and unpleasant, but the center looked clean and well organized. A worker named Mr. Park guided the students through each area, ②explaining how bottles, cans, and paper were sorted. He showed them a machine ③that crushed plastic bottles into small pieces before they were sent to factories. Jimin was surprised to learn that mixed trash, ④thrown into the wrong bin, often ruined an entire batch of recyclables. For example, one greasy pizza box could contaminate a whole pile of clean paper. However, when items were sorted correctly, they could be reused many times, almost like ingredients in a favorite recipe. ⑤Walked home, Jimin realized that her small effort at home truly mattered.

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

Many teachers and parents worry that today's teenagers are losing the ability ①to read long, complex texts. National test scores show a slow decline in reading comprehension over the past ten years, and some experts blame smartphones and short videos for ②shortening students' attention spans. Other researchers disagree with this simple explanation. They point out that teenagers today ③read constantly, just in different forms, such as text messages, captions, and online articles. According to this view, the real problem is not that students read less overall, but that they rarely practice reading long passages without any interruption. A team of researchers recently found that students ④who read at least one full book every month scored noticeably higher on comprehension tests than students who mainly read short online posts. This result suggests that the format of reading, rather than simple screen time, may ⑤being the more important factor behind the changing scores.

Anyone designing a presentation, a curriculum, or a grocery list should attend to a well-documented pattern in human memory known as the serial position effect. When people ①are asking to recall items from a list right after studying it, they consistently remember the items presented at the beginning and end far better than those buried in the middle. The advantage for early items, called the primacy effect, ②arises because those items receive more rehearsal and are more likely to be transferred into long-term storage before subsequent items compete for attention. The advantage for final items, known as the recency effect, ③occurs because those items remain accessible in short-term memory at the moment of recall. Middle items suffer because they must compete for limited rehearsal opportunities while lacking the stability afforded by extended processing. Communicators who ④ignore this pattern risk burying their most important point where it will predictably be forgotten. A more effective strategy, therefore, ⑤places the crucial message at the beginning or end, precisely where memory proves most reliable.

When people have no specific goal, they usually feel ①confused about where to start, and their interest fades within days. For example, a student who simply decides to study harder this year often loses direction because the plan is too ②vague. In contrast, a student who sets a ③clear goal knows exactly what to do every day. A clear goal also makes progress easy to measure, and noticing small improvements keeps people ④encouraged. Setting a specific goal is one of the most ⑤ineffective ways to build lasting motivation.

The human gut hosts trillions of microorganisms whose combined genetic material outnumbers that of the human genome itself many times over. Once dismissed as passive hitchhikers, these bacteria are now understood to actively shape digestion, regulate immune responses, and even influence the production of chemicals that affect mood and behavior. A microbiome disrupted by antibiotics, poor diet, or chronic stress can leave the gut lining more permeable than it should be, allowing substances to leak into the bloodstream that would normally stay contained. _______________. Still, scientists caution that the microbiome varies enormously between individuals, which means a treatment that restores balance in one person's gut may do little for someone else's.

Every spring, the art club at Sejong High School creates one large mural together instead of individual paintings. The process begins with a session where members suggest themes and vote on their favorite idea. (A) Therefore, members regularly step back to compare their section with the rest of the mural. After several weekends, the teams combine their sections into a single image, and the finished mural is displayed near the entrance. (B) Once a theme is chosen, the club divides into small teams, each responsible for one section of the wall. One team sketches the outline while another mixes colors to match the design. (C) Communication becomes essential at this stage, since each section must connect smoothly with the ones beside it. If one team paints too dark a shade, the whole picture can look unbalanced.

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.

A short nap taken in the early afternoon, often called a power nap, can noticeably sharpen attention and mood without leaving a person groggy afterward. (A) If a nap extends much beyond that window, the sleeper risks waking during deep sleep, which produces a foggy, disoriented feeling known as sleep inertia that can persist for thirty minutes or more. (B) The key lies in timing: naps limited to roughly twenty minutes allow the brain to pass through the lightest stages of sleep while avoiding the deeper stages associated with slow-wave activity. (C) Laboratory studies comparing napping and non-napping groups have repeatedly shown that a brief nap improves reaction time and short-term memory almost as effectively as a full night of extra rest. Interestingly, the benefit appears strongest when the nap occurs several hours after waking, since this is when the body's natural dip in alertness makes rest most effective. For this reason, many workplaces now designate quiet rooms where employees can recharge briefly during the day.

Some schools have begun asking students to submit an early draft alongside the final version, specifically to preserve evidence of a student's own original voice. Highlighting an awkward sentence and instantly seeing three smoother alternatives has become a routine part of writing for many students, thanks to AI writing assistants built into word processors and browsers. ( ① ) These tools check grammar and spelling, of course, but the more advanced versions go further, suggesting clearer phrasing, flagging repetitive words, and even adjusting tone to sound more formal or more casual depending on the purpose. ( ② ) Teachers generally welcome the grammar and spelling support, since it frees up class time to focus on argument and structure rather than comma placement. ( ③ ) Concerns grow, however, around the tone and phrasing suggestions, which can gradually nudge every student's writing toward a similar, polished style. ( ④ ) This makes it harder to tell an individual voice from a suggestion generated by the same underlying model. ( ⑤ )
