Recovering from a serious sports injury involves far more than simply ① waiting for torn tissue to heal; it requires a carefully structured program that gradually reintroduces stress to the affected area. Immediately after an injury, rest and gentle range-of-motion exercises help ② preventing stiffness without disturbing the healing tissue. As pain subsides, therapists introduce light resistance training, ③ slowly rebuilding strength in muscles that have weakened from disuse. Only after strength and flexibility approach pre-injury levels ④ do specialists introduce sport-specific drills that mimic the exact movements an athlete will face in competition. Skipping this final stage, even when an athlete feels fully recovered, dramatically increases the risk of re-injury, because general strength does not automatically ⑤ translate into the specific coordination that a particular sport demands.

Psychologists who study daily behavior describe habits through a model ①called the cue-routine-reward loop. This theory explains that every habit begins with a cue, a signal that ②tell the brain to start an automatic behavior. The brain then performs a routine, ③which is the action itself, whether physical or mental. Finally, the brain receives a reward, a positive feeling that makes it want ④to repeat the same behavior. For example, a notification sound can act as a cue that leads a student to check a phone, and the relief from boredom becomes the reward. Similarly, opening a refrigerator out of habit rather than hunger shows how a routine can run without conscious thought. Because this loop operates automatically, breaking a bad habit requires changing the routine while keeping the same cue and reward. Understanding this structure helps people redesign daily patterns more effectively than ⑤relying on willpower alone.

Anthropologist Robin Dunbar ①proposed a concept now known as Dunbar's number, suggesting that human beings can only maintain about one hundred fifty stable social relationships at any given time. This limit, he argued, comes from the size of the human brain, ②which restricts how many meaningful connections a person can cognitively manage. In contrast, many social media users today have hundreds or even thousands of online friends and followers, a number far ③exceeding what Dunbar's research predicts. However, having numerous digital contacts does not necessarily mean that all of these relationships ④are close or emotionally supportive. Most users, when asked, admit that they interact regularly with only a small fraction of their total followers, while the rest remain ⑤largely unnoticing.

Imagine a cafeteria where a healthy salad sits at eye level while fried snacks rest on a low shelf. Nobody is ①forbidden from choosing the snacks, yet most people quietly pick the salad instead. This simple technique illustrates a nudge, a concept from behavioral economics that ②gently guides people toward better choices without restricting their freedom. Companies and governments ③increasingly apply nudges to encourage sustainable consumption. For example, some hotels print reminders on towels stating that most guests reuse them, which ④persuades new guests to do the same and save water. Similarly, energy bills that compare a household's usage with that of efficient neighbors often lead people to reduce electricity use. Unlike strict regulations or heavy taxes, nudges rely on ⑤obvious changes in design rather than force. Critics argue nudges alone cannot solve large environmental problems, but combined with stronger policies, they can meaningfully shift everyday habits toward sustainability.

Insomnia is ① rarely caused by a single factor; it usually emerges from an interaction between psychological stress and physiological arousal that keeps the body from settling into sleep. A common trigger is what researchers call cognitive hyperarousal, in which the mind continues to race with worries about work, relationships, or even the inability to sleep itself, creating a frustrating cycle where anxiety about insomnia becomes a cause of insomnia. At the same time, the body's stress response system can become ② chronically activated, releasing hormones such as cortisol that keep heart rate and body temperature ③ depressed at night, both of which interfere with the natural drop in arousal needed to fall asleep. Poor sleep habits, including irregular bedtimes and excessive screen use before bed, can further ④ weaken the body's internal signals for sleep onset. Because these psychological and physiological factors ⑤ reinforce one another, effective treatment for chronic insomnia addresses both the racing mind and the underlying pattern of physical tension, rather than relying on medication alone.

Jina used to fill her apartment with items she rarely used, believing that owning more things would make her ①happier. After moving twice within a single year, she grew ②energized from packing boxes filled with clothes she had never worn and gadgets she had forgotten she owned. Gradually, however, she noticed that her small apartment felt ③calmer and easier to manage. She also realized that she spent significantly ④less money once she stopped buying things impulsively to fill emotional gaps. Jina's story reflects a broader trend among young adults who increasingly value experiences and simplicity over ⑤accumulating possessions.

Soojin started posting short cooking videos on her phone during her last year of high school, never imagining it could become a career. At first, only a handful of friends watched her clips, and she nearly ①quit after several months without noticeable growth. She kept experimenting, however, adjusting her editing style and posting more ②consistently despite the discouraging numbers. Everything changed when one video demonstrating a simple recipe unexpectedly reached millions of viewers overnight. Within a year, Soojin was earning ③more from her online content than most entry-level jobs would have paid her. Still, she quickly learned that being a creator demanded ④minimal work, since algorithms rewarded frequent uploads and audiences expected fresh content daily. Looking back, Soojin realizes that persistence, rather than luck alone, transformed her hobby into a ⑤demanding profession.

Across many countries, high schools begin classes early in the morning, often before eight o'clock. This schedule assumes that teenagers can simply go to bed earlier to compensate, but biology tells a different story. During adolescence, the body's internal clock shifts later, delaying the release of melatonin until well after ten at night. As a result, most teenagers are not physiologically ready to fall asleep until much later than younger children or adults. When early start times force them to wake before their bodies have completed a full sleep cycle, the mismatch accumulates into a chronic sleep debt that affects concentration and mood throughout the school day. Researchers who study this mismatch argue that _______________. Some school districts that delayed their start times by thirty minutes reported improvements in attendance, suggesting that the timing of the school day matters more than commonly assumed.

주어진 문장: This limitation means the technology has not yet fully replaced conventional factories. Three-dimensional printing technology is changing how products are designed and manufactured across many industries. ( ① ) Unlike traditional manufacturing, which often requires expensive molds and long production times, 3D printers can create complex objects directly from digital files within hours. ( ② ) This flexibility allows companies to produce small batches of customized products without the massive costs typically associated with mass production. ( ③ ) Hospitals now use 3D printing to create prosthetic limbs tailored precisely to individual patients, while automakers use it to build lightweight parts. ( ④ ) However, experts caution that 3D printing still struggles to match the speed of mass production for extremely large orders. ( ⑤ ) As printing materials improve and machines become faster, the technology is expected to play an increasingly central role in future manufacturing.

주어진 문장: She had rehearsed exactly what she would say the moment their eyes finally met. Minji spent nearly every evening watching Jimin, an online creator who streamed cooking videos and chatted casually with her viewers. ( ① ) Over several months, Minji began to feel as though she truly knew Jimin, laughing at her jokes and worrying whenever she mentioned having a difficult week. ( ② ) Whenever Jimin responded to a comment, even a simple one, Minji felt a small thrill of connection, as if they were becoming closer friends. ( ③ ) One day, Minji excitedly waited outside a fan event, hoping that Jimin would recognize her from the countless messages she had sent. ( ④ ) However, Jimin greeted her the same way she greeted every other stranger in line, without any hint of personal recognition. ( ⑤ ) Standing there, Minji slowly realized that the bond she had imagined was entirely one-sided, existing only in her own mind. This type of connection, known as a parasocial relationship, can feel remarkably real despite never being mutual.
