Researchers who ①study teenagers have found a strong link between how well students sleep and how well they perform in school. Students who sleep fewer than seven hours a night tend to score lower on tests of memory and attention than those who ②sleep eight or nine hours, even when the two groups study for the same number of hours. One explanation is that sleep plays an active role in learning: during certain stages of sleep, the brain replays and strengthens information ③encountered during the day, converting fragile short-term memories into more durable long-term ones. When sleep is cut short, this consolidation process is interrupted before it can finish, so material that seemed well understood the night before often ④feel unfamiliar the next morning. For this reason, some schools have begun rethinking early start times, reasoning that an extra hour of sleep might do more for test scores than an extra hour of studying ever ⑤could.

Secondhand trading platforms, once considered a niche market for used goods, have grown into a mainstream part of consumer culture. Rising prices for new products, combined with growing awareness of environmental waste, have encouraged many shoppers to consider used items before purchasing something brand new. These platforms allow individuals to sell clothing, electronics, and furniture directly to other consumers, cutting out traditional retail markups entirely. For younger buyers especially, purchasing secondhand items has become associated with resourcefulness rather than financial necessity, ①change how such purchases are perceived socially. To ②address this problem, many platforms now ③offer buyer protection programs and detailed rating systems for sellers. As trust in these systems continues to grow, secondhand trading is ④expected to ⑤expand even further in the coming years.

As companies collect enormous amounts of personal data to improve their products and target advertisements, serious ethical questions have emerged about how that information should be handled. Employees who work with big data now face ①minimal responsibilities that previous generations rarely encountered, since a single careless decision can expose millions of people's private information. Some argue that strict regulations should govern data collection, even if such rules ②slow innovation and increase costs for businesses. Others insist that self-regulation within companies, guided by clear ethical training, can protect consumers just as ③effectively without stifling progress. Most experts agree that professionals handling sensitive data must be trained not only in technical skills but also in ethical ④decision-making. Universities have begun adding data ethics courses, recognizing that future employees will need to ⑤balance innovation with responsibility.

In the days leading up to an endurance event, many athletes deliberately increase their carbohydrate intake while reducing training volume, a practice known as carbohydrate loading. The strategy is designed to maximize the amount of glycogen, the storage form of carbohydrate, packed into muscle tissue before competition begins. Because glycogen serves as the primary fuel source during prolonged, intense exercise, _______________. Sports nutritionists caution, however, that the timing and composition of meals matter as much as the total quantity of carbohydrate consumed, since eating unfamiliar foods immediately before competition can cause digestive discomfort.

A growing number of people are practicing what is now called digital detox, the deliberate decision to stop using smartphones for a set period. Rather than checking notifications every few minutes, participants unplug for a weekend, a week, or sometimes even longer. Numerous studies suggest that this temporary withdrawal produces real benefits for both the mind and the body. First, attention spans fragmented by constant notifications gradually recover, allowing people to concentrate on single tasks for longer stretches. Second, avoiding screens before bedtime improves sleep quality, since blue light emitted by devices is known to disrupt natural sleep cycles. Third, people freed from their phones often rediscover the pleasure of face-to-face conversations that had been replaced by texting. Critics argue that complete disconnection is impractical in a hyperconnected society, yet even brief, regular breaks appear to restore balance. Therefore, _______________.

(C) Other companies later tried to copy the idea, but most failed to capture the same spontaneous energy.

The pace of technological change has forced professionals to rethink how they approach their careers. (A) As a result, many now treat learning as an ongoing part of their careers rather than something that ends at graduation. (B) A skill considered valuable just five years ago may already be outdated today, forcing workers to update their knowledge constantly. (C) Naturally, some professionals find this constant demand for new skills stressful and difficult to manage alongside other responsibilities.

Colors carry different psychological associations that marketers use strategically when designing logos. (A) Red, for example, often appears in logos related to food and sales, since it tends to stimulate energy and urgency. (B) Blue, on the other hand, frequently appears in logos for banks and technology companies because it suggests trust and stability. (C) These associations, however, are not universal, since the same color can carry very different meanings across cultures.

주어진 문장: Creating a convincing avatar, in other words, is far more complex than simply choosing a picture. The metaverse, a network of interconnected virtual worlds, has begun to generate job opportunities that did not exist just a few years ago. ( ① ) Companies now hire virtual world designers who build digital environments where users can socialize, shop, or attend events. Avatar designers create digital identities that represent users within these spaces, blending artistic skill with technical programming knowledge. ( ② ) Meanwhile, virtual event planners organize concerts, conferences, and product launches entirely within online platforms, reaching audiences that would be impossible to gather in person. ( ③ ) Some analysts remain skeptical, pointing out that the metaverse has not yet attracted the massive user base that early predictions promised. ( ④ ) Nevertheless, major companies continue investing heavily in this technology. ( ⑤ ) For students considering future careers, gaining skills in three-dimensional design and coding may prove valuable.

주어진 문장: Without such outside checks, companies could easily present exaggerated or even false claims as genuine achievements. As consumers become more aware of global social and environmental issues, many now expect companies to take responsibility beyond simply selling products. ( ① ) This expectation has given rise to ethical consumption, in which shoppers consider factors such as fair wages, humane treatment of animals, and environmental sustainability before making purchases. ( ② ) Companies that ignore these concerns risk public backlash, especially when unethical practices are exposed through investigative journalism or social media. ( ③ ) Some corporations have responded by publishing detailed sustainability reports, though critics question whether these documents reflect genuine change or merely serve as public relations tools. ( ④ ) Real accountability, according to many experts, requires independent verification rather than self-reported claims that cannot be easily checked. ( ⑤ ) Consumers, for their part, must also remain vigilant, since a company's marketing language does not always match its actual practices.
