During sleep, the brain does not simply rest; it actively reorganizes the day's experiences into lasting memories through a process called consolidation. Newly formed memories are initially fragile and ①store primarily in a brain region called the hippocampus, ②which has limited long-term capacity. While a person sleeps, particularly during the deep stages of non-REM sleep, neural activity replays these fresh memory traces in rapid, compressed sequences, gradually ③transferring the information to the cortex for more durable, long-term storage. This replay strengthens the connections between neurons that encoded the original experience, ④making the memory more resistant to interference from unrelated events the following day. Sleep researchers have demonstrated this effect experimentally: participants who slept after ⑤learning a list of word pairs recalled more items the next day than participants who remained awake instead.

When Suji transferred to a new school in March, she ①knew no one in her class and felt lonely during lunch and breaks. Her homeroom teacher suggested ②joining a club to make friends more easily. Suji signed up for the photography club, though she had never taken photography seriously before. At the first meeting, older members taught her how ③to adjusting a camera and find a good angle. Because everyone shared photos and gave friendly feedback each week, Suji gradually felt more comfortable with the other members. One rainy afternoon, a fellow member, Hana, ④invited her to photograph the flooded schoolyard together. They laughed while trying to keep their cameras dry, and that moment grew into a real friendship. By the end of the semester, Suji had a small group of friends ⑤who understood her sense of humor.

Marketers have long recognized that perceived scarcity, the sense that a product or opportunity ①are available only in limited quantity or for a limited time, can dramatically increase its desirability, even when the item's intrinsic qualities remain entirely unchanged. This phenomenon, known as the scarcity effect, operates on a simple psychological principle: when something appears difficult to obtain, people tend ②to infer that it must be valuable, since truly worthless items rarely generate genuine competition for possession. A retailer who labels a product as "limited edition" or displays a countdown timer beside a discounted offer exploits this inference, ③prompting customers to make hurried purchase decisions they might otherwise postpone or reconsider. Experimental studies confirm that identical products ④are rated as more desirable and often command higher prices when framed as scarce than when the same products are presented as widely and continuously available. The effect intensifies further when scarcity is attributed to high demand rather than to limited supply alone, since competition from other buyers ⑤introduces an additional layer of urgency absent from mere supply constraints.

Until last spring, Minji rarely thought twice about ①tossing a paper cup into the trash after finishing her coffee. Environmental issues seemed distant, something scientists and politicians should handle rather than an ordinary student like her. That changed when her class was assigned a documentary about plastic waste drifting through the ocean, footage she initially ②expected finding boring. Instead, watching seabirds mistake plastic fragments for food ③left her strangely unsettled, and she found herself thinking about the assignment long after class ended. The next morning, almost without deciding to, she ④slipped her old tumbler into her backpack instead of buying a disposable cup on the way to school. It felt like a small, meaningless gesture at first. However, as weeks passed, she realized that consistently choosing the tumbler, ⑤declining a plastic straw, and reusing a shopping bag were quietly adding up. Small choices, she discovered, become meaningful once repeated.

Dear residents, this notice explains how to use our apartment recycling area ①correctly. The recycling area, located behind the main entrance, is open every day from six to ten in the evening. First, sort your items into the ②labeled sections for paper, plastic, glass, and cans before dropping them off. Boxes should be flattened, and bottles should be emptied, because dirty items are ③hard to recycle. However, please do not leave ④small furniture or electronics in this area at any time. Instead, contact the management office to arrange a separate pickup for those bulky items. For example, broken chairs and old refrigerators require a special sticker before collection. In contrast to ordinary trash, recyclable materials must never be mixed together in one bag. Following these simple rules keeps our shared space ⑤tidy for every family.

A few years ago, spotting a manipulated video required a trained eye and ①specialized software. Today, freely available applications allow almost anyone to swap a face or fabricate a voice ②convincingly enough to fool casual viewers within minutes. This shift has quietly ③reinforced one of the oldest assumptions in human communication: that seeing and hearing something is a reasonably reliable way to confirm it happened. Journalists now face the burden of verifying footage that once would have been accepted as ④self-evident proof. Perhaps more troubling than any single fake video is the broader effect on public trust, in which genuine footage can be ⑤dismissed as fabricated simply because deepfakes exist.

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.

Psychologist Roy Baumeister proposed a concept called ego depletion theory, which suggests that ___________. According to this theory, every act of self-control, from resisting a snack to concentrating on difficult homework, draws from the same limited mental resource. As this resource becomes depleted throughout the day, later decisions require more effort and are more likely to fail. For instance, someone who exercises discipline avoiding distractions all morning may struggle to resist checking a phone by evening. Likewise, dieters report that self-control weakens sharply at night, after hours of resisting food. Some researchers argue that short breaks, adequate sleep, and blood sugar levels can help restore this depleted resource. Although later studies have questioned how strong this effect is, the theory still offers a useful framework for understanding why willpower seems to fade throughout a long day.

One Saturday morning, Jiho carried a heavy bag of old clothes to the donation box near his apartment. He had grown taller over the winter, so many shirts no longer fit him. At first, he almost threw the clothes into the regular trash without thinking twice. However, his older sister reminded him that clean clothes could still help someone else. She explained that donating clothes was like giving a plant a second chance to grow. For example, a jacket he had outgrown might keep another child warm this winter. Therefore, Jiho folded each shirt neatly and placed them gently inside the box. In contrast to his first careless idea, he now felt genuinely happy about his choice. Walking home, Jiho realized that _______________.

Many students confuse the student council with school clubs. In fact, the two groups serve very different purposes. (A) 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. (B) 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 and collect opinions from each class before making decisions. (C) 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.
