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.

Consider a student who ① genuinely intends to study for tomorrow's exam yet, when the evening actually arrives, chooses to watch another episode of a favorite show instead, promising herself she will surely study harder next week. This pattern, in which the pull of an immediate pleasure ② overwhelms the value of a distant benefit, appears again and again across ordinary life, from postponed exercise to delayed savings. People do not necessarily fail to understand that the future reward matters more; rather, whatever happens right now simply feels disproportionately more urgent and vivid than anything scheduled for later. Behavioral economists note that this preference ③ weakens considerably once both options are pushed into the future, which is why planning a diet starting next month feels ④ impossible compared with skipping dessert tonight. Such inconsistency helps explain why gym memberships go unused and retirement accounts remain ⑤ underfunded, despite people's stated intentions.

For decades, productivity advice has focused almost entirely on managing time efficiently, yet many experts now argue this approach ①emphasizes something important. Unlike time, which flows at a ②constant 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 ③peak energy. Similarly, someone who forces themselves to keep working without rest often produces careless mistakes that require additional time to ④correct later. Advocates of energy management recommend identifying one's peak hours and reserving them for demanding work, while saving low-energy periods for ⑤routine tasks.

The science club at Hanul High School is running a project called "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 record their height. At first, many students expected the white light to produce the tallest plants. However, _______________________. 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, recording sunlight, watering time, and temperature. Next month, the club plans to present these findings at the school science fair.

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.

Social psychologists describe a phenomenon called the bystander effect, in which individuals become less likely to help a victim as the number of witnesses increases. Each observer assumes someone else will step in, and this diffusion of responsibility leaves no one willing to act. Cyberbullying magnifies this problem, since a single humiliating post can be witnessed by thousands of people scattered across the internet rather than a few standing nearby. Anonymity intensifies the effect further, allowing silent observers to scroll past cruel comments without feeling accountable for their inaction. Some bystanders even worry that intervening publicly might make them the bully's next target, so they choose to remain silent instead. However, silence signals approval to both the bully and the audience watching the exchange unfold. Experts insist that even a single supportive comment can disrupt this harmful pattern. Therefore, witnesses online must _______________.

The gap between popular belief and scientific evidence about habit formation has surprised many researchers. (A) This finding suggests that people who quit a new habit after only three weeks may simply be giving up too early, not failing at the habit itself. (B) Their results showed that habits took an average of sixty-six days to become automatic, far longer than the widely repeated twenty-one-day figure. (C) To test how long habit formation truly takes, scientists asked volunteers to track a new daily behavior for several months.

주어진 문장: Because the number of likes a post will receive is never guaranteed, every notification carries a small element of suspense. Psychologists have long studied a mechanism called the variable reward schedule, in which rewards arrive unpredictably rather than after every single action. ( ① ) Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. ( ② ) When someone posts a photo, they cannot predict exactly when likes will appear, nor how many they will eventually receive. ( ③ ) This uncertainty triggers a small burst of dopamine each time the phone is checked, regardless of whether the result is disappointing or thrilling. ( ④ ) Consequently, users often refresh their feeds compulsively, hoping the next check will finally bring a satisfying reward. ( ⑤ ) What makes this troubling is that technology companies deliberately designed notification systems using insights borrowed from gambling research, rather than stumbling upon them by accident. Such practices raise serious ethical questions about manipulating users' brains for profit. Therefore, people must consciously recognize this hidden mechanism and set firm limits on their checking habits.

주어진 문장: In other words, the promised environmental benefit is far less certain than it first appears. To compensate for their carbon emissions, many individuals and companies now purchase carbon offsets, financial credits that fund projects such as planting trees or building renewable energy plants. ( ① ) The idea is appealing: paying for an equivalent amount of carbon to be absorbed elsewhere should cancel out the harm caused by activities like flying. ( ② ) However, critics argue that this system often functions as a convenient excuse for postponing genuine emission cuts rather than achieving them. ( ③ ) For example, a newly planted forest may take decades to absorb the promised carbon, and it could later burn down or be cut, erasing any benefit. ( ④ ) Moreover, some offset projects would have happened anyway, meaning the credits fund nothing truly additional. ( ⑤ ) Therefore, relying heavily on offsets allows businesses to maintain harmful practices while appearing responsible. Experts insist that offsetting should complement, not replace, direct reductions in fossil fuel use if the strategy is to remain credible.

주어진 문장: Fortunately, this cycle is not impossible to reverse. An echo chamber refers to an online environment where people are mainly exposed to opinions that already match their own beliefs. ( ① ) This phenomenon occurs because social media algorithms tend to recommend content similar to what users have previously liked or shared, gradually narrowing the range of perspectives they encounter. ( ② ) As a result, individuals inside an echo chamber rarely engage with viewpoints that challenge their existing assumptions, which allows their original beliefs to grow increasingly extreme over time. ( ③ ) For example, someone who frequently reads articles supporting one political party may begin to see the opposing party as entirely unreasonable, having never seriously considered its arguments. ( ④ ) Political polarization, a significant issue in many countries today, is often linked to this pattern of selective exposure. ( ⑤ ) Breaking out of an echo chamber requires deliberately seeking information from diverse sources, even when those sources present uncomfortable or unfamiliar ideas.
