Good morning, residents of Green Apartment! We would like to introduce a simple way to protect our environment. Used batteries, ①what contain harmful chemicals, should never be ②thrown away with regular trash. If these chemicals leak into the soil, they can pollute water and harm plants. Therefore, our building has installed a special collection box for used batteries near the main entrance. Please place your old batteries inside this box instead of the trash can. The box, ③which is emptied every month, is easy for anyone ④to use. For example, small button batteries from watches and toys can also be dropped in the box. However, batteries ⑤that are still working should not be thrown away at all. We appreciate your effort to keep our neighborhood clean and safe. Thank you for your cooperation and kindness.

Communication scholar Elisabeth Noelle-Neumann proposed the spiral of silence theory to explain why certain opinions ①dominate public discussion while others fade into invisibility. According to this theory, individuals constantly observe their surrounding environment to judge which opinions are widely accepted and which are not. When people sense that their own view belongs to a minority, they often choose to stay ②vocal rather than risk social isolation or criticism. This silence, however, creates a distorted impression that the minority opinion is even ③rarer than it actually is, discouraging additional supporters from speaking up. Over time, this cycle spirals downward, allowing the dominant opinion to appear increasingly ④unanimous while dissenting voices disappear from visible conversation. Social media platforms can intensify this spiral, since visibility metrics make popular opinions instantly ⑤noticeable while unpopular ones remain hidden.

The planning fallacy describes the tendency to ①underestimate how long a task will take, even when experience suggests otherwise. Psychologists who studied this bias found that people focus mainly on an ②idealized, best-case version of a project. They focus less on how similar projects actually unfolded before. Large construction projects offer another example. Officials frequently predict completion dates that later prove far too ③optimistic once delays appear. One reason this bias persists is that people ④rarely review their history of missed deadlines, relying instead on hopeful imagination. By anchoring predictions to real outcomes, planners can produce estimates that are considerably more ⑤inaccurate.

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. 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. Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at trapping heat in the atmosphere. 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. Nutritionists also emphasize that flexitarian eating is easier to maintain than full vegetarianism, because it allows flexibility rather than demanding absolute discipline. Therefore, many environmental groups now promote flexitarianism as a realistic first step, believing that _______________.

Our school's book club, Page Turners, meets every Wednesday to discuss a book the members chose. At the start of each month, students suggest titles and vote to pick one. This way, everyone feels some ownership over what the club reads next. Before each meeting, members read several chapters and prepare a few questions. During the meeting, the leader opens discussion by asking a question about the story's main idea. Then members take turns sharing their opinions, even when they disagree with each other. For example, students once argued for a long time about a character's difficult choice. Such debates, though sometimes loud, help members understand different points of view. At the end of the semester, the club holds an event to recommend favorite books. Through this process, reading becomes _______________.

Setting up and using this goal-tracking app only takes a few simple steps. (A) After that, choose how often you want to practice the goal, and the app will send a gentle reminder at the chosen time. (B) First, create an account using your email address, and then tap the plus button to add a new goal. (C) Finally, tap the checkmark whenever you complete a task, and the app will record your streak automatically.

This mismatch between internal time and local time is the true source of the problem, not the flight itself. 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. ( ① ) The discomfort arises because the body's internal clock, which governs sleep, hunger, and alertness, continues to run on the schedule of the departure city even after landing. ( ② ) 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. ( ③ ) Flying eastward tends to produce more severe symptoms than flying westward, because advancing the internal clock forward is generally harder for the body than delaying it. ( ④ ) 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. ( ⑤ ) Without such adjustments, travelers may continue to experience disrupted sleep and reduced concentration for several days after a long international flight.

주어진 문장: At first glance, this seems to suggest that Dunbar's theory no longer applies in the digital age. Anthropologist Robin Dunbar proposed a concept now known as Dunbar's number, suggesting that human beings can only maintain about one hundred fifty stable social relationships at any given time. ( ① ) This limit, he argued, comes from the size of the human brain, which restricts how many meaningful connections a person can cognitively manage. ( ② ) In contrast, many social media users today have hundreds or even thousands of online friends and followers, a number far exceeding what Dunbar's research predicts. ( ③ ) However, having numerous digital contacts does not necessarily mean that all of these relationships are close or emotionally supportive. ( ④ ) Most users, when asked, admit that they interact regularly with only a small fraction of their total followers, while the rest remain largely unnoticed. ( ⑤ ) Therefore, Dunbar's number reminds us that genuine, lasting relationships require consistent effort and attention, something that a large online network alone cannot provide.

주어진 문장: It was a small decision, but it suddenly felt like the beginning of something new. On the first day of the club fair, the gym was filled with noise and color. ① Every table had a banner, and members called out to new first-graders like me. My friend Somin dragged me toward the robotics club, insisting it would suit me. ② However, the long list of coding projects looked too complicated for a beginner. Just then, I noticed a quiet table where students were sketching posters together. ③ A calm senior named Jian explained that the art club welcomed complete beginners. She showed me a sketchbook filled with simple drawings by first-year members. ④ Her gentle voice made me feel relaxed for the first time that day. Without much thought, I wrote my name on the sign-up sheet before leaving. ⑤ Walking out of the gym, I finally felt that I belonged in this new school.

주어진 문장: In short, mistakes become valuable only when a person chooses to learn from them. When people fail to reach a goal, they often feel embarrassed and want to give up. ( ① ) However, the way a person thinks about failure can change what happens next. ( ② ) Some people believe failing means they simply lack ability, so they stop trying. Others see failure differently: they treat it as useful information that shows what needs to change. ( ③ ) For example, a student who fails a math test might later ask the teacher which questions were weak points and study those areas more carefully. ( ④ ) Over time, people who view failure as a lesson rather than a final judgment tend to keep working toward their goals, even after several setbacks. ( ⑤ )
