Skipping a proper warm-up before intense exercise might seem like a harmless way to save a few minutes, but the practice ①carries real physiological costs. A cold muscle is stiffer and less elastic than a warm one, making it considerably more prone to strains and tears when suddenly ②asked to contract forcefully. Gradually raising body temperature through light activity increases blood flow to the muscles, ③allowing oxygen to reach tissue more efficiently and enabling nerve signals to travel faster between the brain and the muscle fibers. A proper warm-up also raises heart rate gradually, ④easing the cardiovascular system into strenuous work rather than shocking it with a sudden demand. Athletes who warm up thoroughly tend to report better performance in the early minutes of competition, since their bodies are already primed rather than ⑤adjust on the fly.

Many companies now advertise themselves as environmentally responsible, yet a growing number of these claims turn out to be ①misleading. This practice, known as greenwashing, occurs when a business spends more effort marketing its products as eco-friendly than actually reducing environmental harm. A company might launch a recycled-packaging line while continuing to pollute rivers through its main factories, creating a false impression of genuine change. Such tactics ②deceive well-intentioned consumers who wish to shop responsibly but lack the tools to ③verify corporate claims. In contrast, truly sustainable businesses publish detailed, independently verified data about their emissions and supply chains, allowing outsiders to check their progress. Therefore, shoppers should look beyond vague labels like green or natural and instead search for ④recognized certifications, transparent reports, and measurable targets. Without such scrutiny, greenwashing will keep ⑤declining, undermining public trust and slowing the broader shift toward an economy that truly protects the planet.

The term green premium describes the ①reduced cost that consumers must pay when they choose an environmentally friendly product or energy source over a conventional, cheaper alternative. For example, an electric vehicle or solar-powered appliance often carries a higher price tag than its gasoline-powered or coal-based counterpart, even though it produces fewer emissions over time. This price gap frequently ②discourages shoppers who support sustainability in principle but cannot justify the additional expense within a limited household budget. In contrast, wealthier consumers can ③absorb the premium more easily, which creates unequal participation in green markets. To ④narrow this gap, governments have introduced subsidies and tax credits that lower upfront costs, while companies invest in research to make clean technologies cheaper to manufacture. As production scales up and innovation continues, many economists expect the green premium to ⑤shrink steadily, eventually making sustainable choices the more affordable option for most consumers.

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

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 ___________.

Ethical consumption has placed new pressure on companies to justify their practices publicly. (A) Yet critics point out that such reports are sometimes little more than carefully worded public relations documents. (B) In response, many corporations now publish detailed reports describing their environmental and labor practices. (C) For this reason, many experts insist that independent audits are necessary to confirm whether ethical claims are genuine.

The rise of autonomous vehicles has created both excitement and anxiety within the transportation industry. (A) In particular, long-distance trucking jobs are expected to shrink significantly as autonomous trucks become more common on highways. (B) At the same time, entirely new positions are emerging, such as remote operators who monitor fleets of self-driving vehicles from control centers. (C) On one hand, many professional drivers fear that automation will eliminate the jobs they currently depend on.

주어진 문장: This explains why progress often feels rapid and motivating during the earliest days of learning something new. The twenty-hour rule proposes that years of practice are not needed to become skilled at a new activity. ( ① ) Only about twenty hours of effort are needed to reach a useful level. Unlike theories claiming true mastery requires ten thousand hours, this rule targets a more modest goal. That goal is simple competence for everyday use. ( ② ) According to supporters, practicing any new skill produces the fastest visible improvement, since a beginner has room to grow. ( ③ ) Someone learning guitar can typically strum simple chords and follow a basic song within twenty hours of daily practice. ( ④ ) Likewise, a language learner may soon order food or ask directions without years of formal study. ( ⑤ ) Advocates emphasize that the twenty hours must be deliberate and focused, broken into short daily sessions rather than one long stretch. The hours should be aimed at fixing weaknesses rather than repeating what one already knows.

This process, though it may sound simple, triggers a remarkable series of adaptations throughout the cardiovascular system. Aerobic exercise, such as jogging, swimming, or cycling at a steady pace, strengthens the heart by forcing it to pump larger volumes of blood with each beat. ( ① ) Over weeks of consistent training, the heart gradually enlarges and becomes more efficient, meaning it can deliver the same amount of oxygen to working muscles while beating fewer times per minute. ( ② ) This adaptation explains why trained athletes often have a much lower resting heart rate than sedentary individuals of the same age. ( ③ ) Beyond the heart itself, aerobic activity encourages the body to build new capillaries within muscle tissue, improving the delivery of oxygen and nutrients at a cellular level. ( ④ ) Researchers have also found that regular aerobic exercise reduces inflammation throughout the body and improves the way cells respond to insulin. ( ⑤ )

Because the keyboard nudges people toward its own suggestions, some linguists worry that autocomplete may be quietly narrowing everyday vocabulary. Long before a user finishes typing a sentence, the keyboard on most smartphones has already begun guessing what word comes next. ( ① ) This feature relies on a language model trained to notice which words commonly follow one another, so it can offer a shortlist of likely candidates above the keyboard, saving users countless keystrokes over the course of a day. ( ② ) The system also adapts to each individual, gradually learning a person's favorite phrases, slang, and even the names of friends that no generic dictionary would recognize. ( ③ ) This constant personalization, however, creates a subtle side effect that few users notice. ( ④ ) This small habit, choosing a convenient suggestion rather than searching for the more precise or original word one might otherwise have chosen, can add up over years of daily use. ( ⑤ )
