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 ① store primarily in a brain region called the hippocampus, ② which 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 ③ transferring the information to the cortex for more durable, long-term storage. This replay strengthens the connections between neurons that encoded the original experience, ④ making the memory more resistant to interference from unrelated events the following day. Sleep researchers have demonstrated this effect experimentally: participants who slept after ⑤ learning a list of word pairs recalled more items the next day than participants who remained awake instead.

A smartwatch strapped to a runner's wrist can now do far more than simply count steps; it monitors heart rate variability, running form, and recovery time, then uses that data to suggest a training plan ① tailored to the individual rather than a generic weekly schedule. When the device detects signs of overtraining, such as an unusually high resting heart rate several mornings in a row, it may recommend a ② lighter workout or an extra rest day before fatigue turns into an actual injury. Amateur athletes often credit this kind of guidance with helping them train more ③ consistently without pushing their bodies too hard. Sports scientists note an important caveat, however: a wrist-based sensor cannot fully capture the same physiological detail available in a professional lab, so its suggestions should be treated as an ④ infallible medical judgment rather than a helpful guideline, particularly for anyone ⑤ managing a chronic health condition.

Behavioral economists use the term status quo bias to describe a tendency to prefer the present situation over a new alternative, even when the alternative would bring greater benefits. This bias helps explain why many households hesitate to switch to renewable energy, such as installing solar panels on their roofs. Although solar panels can lower electricity bills over time, homeowners often stick with their current power source because it feels safe and requires no immediate effort. In contrast, switching demands research, upfront cost, and trust in unfamiliar technology, all of which can seem risky compared with doing nothing. For example, a neighborhood association might repeatedly postpone a vote on shared solar panels, not because the plan is flawed, but because members are reluctant to leave their routine. Therefore, boosting renewable adoption may depend less on proving its advantages and more on _______________.

Team sports place athletes in a uniquely social form of competition, one where individual skill alone rarely determines the outcome of a match. Sports psychologists have long studied why some groups of talented individual players fail to perform as a cohesive unit while other, less individually skilled teams consistently exceed expectations. Trust among teammates appears to be a decisive factor, since _______________. Clear and consistent communication during high-pressure moments further reduces the hesitation and confusion that can unravel a team's coordination in front of a crowd.

Many teenagers check their social media accounts dozens of times a day, worried that they might miss something important happening among their friends. This anxiety, known as FOMO, or the fear of missing out, arises when people believe that others are enjoying experiences from which they themselves are excluded. For example, a student scrolling through photos of a party she was not invited to may suddenly feel a wave of loneliness and regret, even though the event has already ended. Constantly refreshing feeds to avoid missing such updates, however, makes it difficult to concentrate on schoolwork or conversations happening in the present moment. Moreover, this endless comparison with curated highlights of other people's lives tends to deepen feelings of anxiety rather than relieve them. Therefore, students should learn to ___________.

An echo chamber refers to an online environment where people are mainly exposed to opinions that already match their own beliefs. 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. 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. 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. Political polarization, a significant issue in many countries today, is often linked to this pattern of selective exposure. Breaking out of an echo chamber requires ___________.

Psychologist Leon Festinger introduced social comparison theory, which explains that people evaluate their own abilities and opinions by comparing themselves with others. According to this theory, individuals engage in upward comparison when they measure themselves against someone who appears more successful, attractive, or accomplished. Social media platforms, filled with carefully edited photos and exaggerated achievements, provide endless opportunities for this kind of comparison. For instance, a teenager browsing vacation pictures posted by classmates may begin to feel that her own ordinary life is somehow inadequate. Unlike comparing oneself with someone in a similar position, which can sometimes boost confidence, upward comparison frequently triggers envy, dissatisfaction, and lower self-esteem. Researchers have found that frequent upward comparison online is linked to higher depression and anxiety. Consequently, this theory helps explain why ___________.

The two-minute rule offers a simple but powerful strategy for anyone who struggles to begin a new habit. (A) Once the habit of showing up regularly is established, the duration or intensity of the activity can gradually increase without much resistance. (B) The idea behind this rule is that most people quit a new habit not because the activity itself is difficult, but because starting feels intimidating. (C) By reducing a habit to something as simple as reading one page or doing one push-up, the initial hesitation to begin nearly disappears.

In response, some platforms have begun inserting occasional wildcard suggestions that are deliberately unrelated to past viewing habits. After a viewer finishes an episode, a streaming service rarely leaves the choice of what to watch next entirely up to chance. ( ① ) Instead, a recommendation algorithm compares that viewer's habits with patterns drawn from millions of other users who watched similar content, then ranks thousands of titles in order of predicted interest. ( ② ) This approach keeps viewers engaged far longer than a simple list of new releases ever could, which is precisely why streaming companies invest so heavily in refining it. ( ③ ) The system is not without drawbacks, however. Because the algorithm favors titles similar to what a viewer already enjoys, it can quietly narrow someone's exposure to unfamiliar genres, directors, or cultures, creating a comfortable but repetitive bubble. ( ④ ) These wildcard picks are meant to counteract this narrowing effect and keep recommendations from becoming too predictable. ( ⑤ )

주어진 문장: Yet this same tendency also carries a hidden drawback. Sociologists use the term homophily to describe the tendency of people to form connections with others who share similar backgrounds, opinions, or interests. ( ① ) This principle explains why classmates from the same major often become close friends, while coworkers with shared hobbies naturally gravitate toward one another. ( ② ) Because similarity reduces the effort required to understand another person's perspective, relationships built on shared traits tend to feel comfortable and require less negotiation. ( ③ ) However, this same comfort can narrow the range of viewpoints someone encounters, since surrounding oneself with similar people limits exposure to different ideas. ( ④ ) Social media platforms intensify this pattern through recommendation algorithms that suggest new friends based on shared interests or similar browsing history. ( ⑤ ) As a result, users often find their online circles becoming increasingly homogeneous, filled with people who think and behave much like themselves.
