Insomnia is rarely caused by a single factor; it usually emerges from an interaction between psychological stress and physiological arousal that ①keeps the body from settling into sleep. A common trigger is what researchers call cognitive hyperarousal, in which the mind continues ②to racing with worries about work, relationships, or even the inability to sleep itself, creating a frustrating cycle where anxiety about insomnia becomes a cause of insomnia. At the same time, the body's stress response system can become chronically activated, ③releasing hormones such as cortisol that keep heart rate and body temperature elevated at night, both of which interfere with the natural drop in arousal needed to fall asleep. Poor sleep habits, including irregular bedtimes and excessive screen use before bed, can further ④weaken the body's internal signals for sleep onset. Because these psychological and physiological factors reinforce one another, effective treatment for chronic insomnia addresses both the racing mind and the underlying pattern of physical tension, rather than ⑤relying on medication alone.

Social media researchers use the term context collapse ①to describe what happens when a single online post ②reach audiences that would normally remain separate in offline life. In daily interactions, people naturally adjust their tone and content depending on whether they are ③speaking with family, close friends, or professional colleagues. However, a typical social media feed merges these distinct audiences into one undivided crowd, since a single post can simultaneously reach parents, employers, and casual acquaintances. Consequently, users often struggle to decide which version of themselves ④to present, knowing that a joke suitable for close friends might seem unprofessional to a supervisor. This tension forces many users to either self-censor heavily or maintain multiple separate accounts ⑤tailored to different audiences.

Online advertising algorithms analyze enormous amounts of user data ①to determine which products a person is most likely to purchase. Every click, search, and pause while scrolling provides information that these systems use ②to refine future advertisements. Supporters argue that this level of precision benefits consumers by ③reducing exposure to irrelevant advertisements and highlighting products they genuinely need. Critics, however, worry that constant exposure to tailored ads can encourage unnecessary spending, since algorithms ④is specifically designed to identify and exploit individual weaknesses. Greater transparency, many experts argue, would allow consumers ⑤to make more informed decisions about their own online behavior.

Every spring, the art club at Sejong High School creates one large mural ①together instead of individual paintings. The process begins with a session where members suggest themes and vote on their favorite idea. 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. Communication becomes ②unnecessary 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 ③unbalanced. Therefore, members ④regularly step back to compare their section with the rest of the mural. After several weekends, the teams combine their sections into a single image. The finished mural is displayed near the entrance, reminding everyone what ⑤cooperation can achieve.

As companies collect enormous amounts of personal data to improve their products and target advertisements, serious ethical questions have emerged about how that information should be handled. Employees who work with big data now face ①minimal responsibilities that previous generations rarely encountered, since a single careless decision can expose millions of people's private information. Some argue that strict regulations should govern data collection, even if such rules ②slow innovation and increase costs for businesses. Others insist that self-regulation within companies, guided by clear ethical training, can protect consumers just as ③effectively without stifling progress. Most experts agree that professionals handling sensitive data must be trained not only in technical skills but also in ethical ④decision-making. Universities have begun adding data ethics courses, recognizing that future employees will need to ⑤balance innovation with responsibility.

Dear members of the Debate Club, I am writing to let you know that our regular meeting time has been changed. We usually meet in Room 304 every Wednesday after school, but _______________. Instead, our meeting will be held in the library on Thursday at the same time. Please bring the debate topic that you prepared last week, since we will practice our arguments together. If you cannot attend the new meeting time, please reply to this email by Tuesday evening. We also need two volunteers to arrange the chairs and tables before the meeting begins. Mr. Park, our club advisor, will join us this time to give feedback on our speaking skills. Thank you for your understanding, and I look forward to seeing everyone on Thursday.

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 _______________.

주어진 문장: Creating a convincing avatar, in other words, is far more complex than simply choosing a picture. The metaverse, a network of interconnected virtual worlds, has begun to generate job opportunities that did not exist just a few years ago. ( ① ) Companies now hire virtual world designers who build digital environments where users can socialize, shop, or attend events. Avatar designers create digital identities that represent users within these spaces, blending artistic skill with technical programming knowledge. ( ② ) Meanwhile, virtual event planners organize concerts, conferences, and product launches entirely within online platforms, reaching audiences that would be impossible to gather in person. ( ③ ) Some analysts remain skeptical, pointing out that the metaverse has not yet attracted the massive user base that early predictions promised. ( ④ ) Nevertheless, major companies continue investing heavily in this technology. ( ⑤ ) For students considering future careers, gaining skills in three-dimensional design and coding may prove valuable.

주어진 문장: These various booths give every member a chance to show what they have practiced throughout the year. Every October, Greenfield High School holds a festival that gives every club a chance to shine. ① This year's festival will take place on October 15th, running from nine in the morning until four in the afternoon. ② Clubs that want to run a booth must apply to the student council by October 1st, since space in the gym is limited. ③ The science club will present simple experiments that are both safe and exciting to watch. The art club, meanwhile, will display paintings that members have created throughout the semester. ④ The cooking club plans to sell snacks prepared by its own members, and all the profits will be donated to a local shelter. ⑤ Because many visitors are expected, teachers will supervise each booth carefully to keep students safe. Anyone curious about club life is warmly encouraged to visit and enjoy the festival.

However, even confident swimmers can get into trouble in open water. Summer is the best time to enjoy swimming pools, rivers, and beaches with family and friends. ( ① ) First, always swim in areas that are supervised by a lifeguard, and never swim alone, even if you are a strong swimmer. ( ② ) It is also important to check the weather and water conditions before entering the water, since strong currents and sudden storms can appear without warning. ( ③ ) Wearing a life jacket in open water is essential, especially for children and beginners. ( ④ ) Taking regular breaks during long swims helps prevent exhaustion. ( ⑤ ) Learning basic rescue skills is another good habit that could help you save a life someday.
