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, ①arises when people believe that others are enjoying experiences from which they themselves are excluded. For example, a student ②scrolling 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 ③refreshed 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 ④deepen feelings of anxiety rather than relieve them. Therefore, students should learn ⑤to limit their social media use and focus more attention on the relationships and activities directly in front of them.

Parents and coaches sometimes worry that heavy resistance training might damage the growth plates in a young athlete's bones, cartilage regions near the ends of long bones that are ① responsible for lengthening as a child develops. This concern kept strength training out of many youth programs for decades. However, extensive research over the past twenty years has found ② little evidence that properly supervised resistance training harms growth plates in healthy children. The actual risk arises not from lifting weights itself but from ③ poor technique, excessive load, and inadequate supervision. Major pediatric and sports medicine organizations now generally agree that structured strength programs, when taught with correct form and appropriate weight, can safely ④ improve bone density, coordination, and injury resistance in young athletes. The key variable, in other words, is not whether children lift weights but how carefully that training is ⑤ ignored.

Sleep apnea is a disorder in which breathing repeatedly stops and restarts during sleep, often because the muscles at the back of the throat ① relax too much and block the airway. Each pause can last from a few seconds to over a minute, and it may occur dozens of times in a single night without the sleeper ever ② waking up fully. Because these interruptions rarely produce a clear memory the next morning, many people remain ③ unaware that anything is wrong, even as chronic fatigue, headaches, and irritability build up over months. Doctors therefore rely less on a patient's own account of the night and more on ④ subjective measurements, such as overnight oxygen levels and airflow patterns recorded in a sleep laboratory. Left untreated, the disorder has been linked to serious long-term risks, including high blood pressure and heart disease, which makes an accurate diagnosis far more ⑤ urgent than its subtle nighttime symptoms might suggest.

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 ___________.

Every day, email providers quietly block billions of unwanted messages before they ever reach a user's inbox, a task that would be impossible without an AI filtering system running constantly in the background. (A) This creates a constant back-and-forth, since spammers study which messages get blocked and then adjust their wording to slip through again. (B) The filter examines each incoming message for suspicious patterns, including certain keywords, unusual sender addresses, and formatting tricks that scammers commonly rely on to slip past detection. (C) What makes the system effective is that it keeps learning after launch, since a user's action of marking or rescuing a message becomes new training data.

Many self-help books emphasize the cue-routine-reward loop as a tool for building better habits. (A) For example, athletes who want to build a stretching habit often rely on a specific cue, such as arriving at the gym, to trigger the same short routine every time. (B) Over time, this consistent pairing strengthens the neural pathway connecting the cue to the routine, making the behavior feel almost automatic. (C) According to this model, every habit consists of three connected parts: a cue that triggers behavior, a routine that follows, and a reward that reinforces it.

Skipping a proper warm-up before intense exercise might seem like a harmless way to save a few minutes, but the practice carries real physiological costs. (A) Gradually raising body temperature through light activity, however, increases blood flow to the muscles and helps nerve signals travel faster between the brain and the muscle fibers. (B) A cold muscle, after all, is stiffer and less elastic than a warm one, making it considerably more prone to strains and tears when suddenly asked to contract forcefully. (C) For this reason, coaches treat warm-up routines not as optional preparation but as an essential part of training itself.

Researchers have long debated why people often behave so differently once they log onto the internet. (A) On the other hand, this same freedom can turn destructive when users hide behind anonymity to attack others without fear of being identified. (B) One explanation lies in the reduced sense of accountability that anonymity and physical distance create, allowing hidden emotions to surface more easily. (C) For instance, someone who feels lonely might open up honestly in an online forum, sharing feelings they would never mention to coworkers.

주어진 문장: This constant awareness of human presence is what distinguishes cobots from older industrial machines. Modern factories increasingly rely on collaborative robots, often called cobots, which are designed to work safely alongside human employees. ( ① ) Unlike traditional industrial robots that operate behind safety cages, cobots use sensors to detect nearby workers and adjust their movements accordingly. ( ② ) This technology allows humans and machines to share the same workspace without the risk of dangerous accidents. ( ③ ) In practice, cobots typically handle repetitive or physically demanding tasks, while human workers focus on tasks that require judgment and fine motor skills. ( ④ ) This division of labor increases overall efficiency, since each side contributes what it does best. ( ⑤ ) Manufacturers who have introduced cobots report fewer workplace injuries and higher worker satisfaction.

The convenience comes at a cost that few passengers consider, however. A navigation app calculating a route rarely relies on distance alone; instead, it constantly weighs real-time traffic reports, past congestion patterns for that time of day, and even data from other drivers' phones currently on the road. ( ① ) This flood of information allows the app to reroute a driver away from a sudden accident within seconds, often before the driver has any idea the accident occurred at all. ( ② ) When thousands of drivers are simultaneously redirected onto the same shortcut, that quiet side street can quickly become as congested as the highway it was meant to help travelers avoid. ( ③ ) Residents of these once-quiet neighborhoods have increasingly complained about the sudden surge of unfamiliar traffic. ( ④ ) They argue that an algorithm optimizing for individual convenience can end up creating a new, entirely different problem for the wider community. ( ⑤ )
