The science club at Hanul High School is running a project ①called "Grow Light." It tests how different colors of light affect plant growth. Each week, members place identical bean sprouts under red, blue, and white light and ②record their height. At first, many students expected the white light ③to produce the tallest plants. However, the results showed that plants under red light grew noticeably ④fast than the others. The club's advisor explained this by comparing light to food. Just as people need certain nutrients to grow strong, plants absorb certain colors of light more efficiently than others. To make the data reliable, students repeat each trial three times and calculate the average. They also keep a shared notebook, ⑤recording sunlight, watering time, and temperature.

Every cell in the human body follows an internal timer known as the circadian rhythm, a roughly twenty-four-hour cycle that ①governs when we feel alert and when we feel drowsy. This clock is regulated primarily by a tiny cluster of neurons in the brain that responds to light entering through the eyes. When morning sunlight strikes the retina, the cluster signals the body to ②suppress sleep hormones and raise body temperature, preparing us for activity. As evening approaches and light fades, the same mechanism triggers the release of melatonin, a hormone that ③promotes drowsiness. Because this rhythm evolved around the natural cycle of day and night, modern habits such as staying indoors under artificial light or working night shifts can push the internal clock ④out of sync with the external environment. Such misalignment does not simply cause tiredness; it has also been associated with digestive problems and ⑤heightened concentration, suggesting that timing matters as much as total sleep hours.

Attention all club leaders: applications for the club budget are now ①closed. If your club wants support for materials, events, or competitions, please follow the steps below. First, download the budget request form from the school website and fill in your club's name, purpose, and requested amount. Second, attach a short plan explaining how the money will be used, since forms without a clear plan will not be reviewed. Third, submit the ②completed form to the teacher in charge of student activities by August 14th. Applications received after the deadline will not be ③accepted. Once submitted, each request will be reviewed by the budget committee, which meets every Friday. ④Approved clubs will receive their funds within two weeks, and results will be posted on the club bulletin board. Please contact Mr. Han in the activities office if you have any ⑤questions.

Internet activist Eli Pariser introduced the term filter bubble to describe a phenomenon created by online algorithms. Social media platforms and search engines ①constantly track which links users click and how long they linger on certain posts. Based on this data, algorithms ②predict what each individual is most likely to enjoy and quietly prioritize similar content in future results. As a result, two people who type the same search query can receive strikingly different results, each tailored to personal history. This automatic filtering happens ③silently, without users ever deciding to limit what they see. Consequently, many people gradually ④gain access to viewpoints that challenge their existing beliefs, even though they never intended to avoid them. Pariser warned that this invisible curation could weaken democratic debate by narrowing public discussion. Therefore, some experts argue that platforms should reveal how content is filtered, letting users ⑤knowingly escape their own bubbles.

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.

Many students confuse the student council with school clubs. In fact, _______________________. The student council is an official body that represents the whole school. It manages shared issues such as rules, events, and communication with teachers. For example, council members often organize the school festival. They also collect opinions from each class before making decisions. A club, in contrast, is a small group formed around one shared interest, such as music or art. While the council must consider the needs of every student, a club can focus narrowly on what its own members enjoy. Therefore, joining the council usually requires an election, whereas joining a club simply requires genuine interest. Some students eventually do both, using the council to build leadership skills and a club to develop a personal passion.

Jimin joined the school band club in March, but she had never performed before an audience. The club's first concert was only two weeks away, and everyone felt nervous. During practice, her hands shook whenever the song reached the chorus, and she kept missing the same chord. Instead of laughing at her mistakes, the other members waited patiently and played the section again with her. The drummer, Suho, suggested that she focus on just one part at a time. Slowly, her fingers grew more confident, and the chord that once felt impossible began to feel natural. The club practiced until the melody sounded smooth the night before the concert. When Jimin walked onto the stage, she thought of her friends' patience instead of her fear. The audience clapped warmly, and she realized _______________________.

For decades, productivity advice has focused almost entirely on managing time efficiently, yet many experts now argue this approach overlooks something important. This alternative approach, known as energy management, suggests that ___________. Unlike time, which flows at a constant rate, human energy naturally rises and falls in cycles shaped by sleep, food, and mental fatigue. A person who tackles difficult tasks during a low-energy period, for instance, may need two hours to finish what takes thirty minutes at peak energy.

A documentary director named Mira set out on her first trip to a remote Arctic glacier, eager to film its towering cliffs of blue ice. (A) Comparing the two sets of footage side by side, she realized that a transformation she had expected to take centuries was actually happening within a single decade, which convinced her that climate change was an urgent process reshaping landscapes before her eyes. (B) Five years later, however, she returned to the very same coordinates, only to discover that the glacier had retreated so dramatically that the ice cliffs had nearly disappeared, leaving bare rock and meltwater behind. (C) Standing before the massive wall of ice on that first trip, she assumed that such an enormous structure could hardly change within a lifetime.

주어진 문장: This misconception, sometimes called the twenty-one-day myth, has been repeated so often that many people accept it without question. Many people believe that a new habit becomes automatic after only twenty-one days, but researchers who examined real behavior found a different number. ( ① ) This project, called the 66-day habit formation study, tracked volunteers who tried to adopt a new daily habit, like drinking water with lunch. ( ② ) Researchers measured how automatic each action felt over time and found that habits needed an average of sixty-six days to become effortless. ( ③ ) Yet the actual time varied widely, ranging from about eighteen days for simple habits to over two hundred days for difficult ones. ( ④ ) This wide range explains why the popular twenty-one-day claim, though easy to remember, rarely matches real experience. ( ⑤ ) For instance, flossing might feel automatic within a few weeks, while jogging every morning may take months to feel natural. The study's central lesson is that patience matters more than speed when building lasting habits.
