Across the world, teenagers are chronically short on sleep, often getting two or three hours less than the eight to ten hours experts recommend for their age. Part of the problem lies in biology: as puberty begins, the body's internal clock naturally shifts later, ①making it difficult for teenagers to fall asleep before eleven at night. Yet school start times rarely adjust to this shift, ②forcing students to wake before their bodies are ready. The consequences extend well beyond simple tiredness. Chronic sleep loss during adolescence has been linked to impaired concentration, weakened memory, and a higher risk of anxiety and depression. It can also disrupt the hormones ③that regulating appetite, contributing to unhealthy weight gain over time. Some school districts have experimented with ④delaying start times by even thirty minutes, and early results suggest that students who gain that extra rest show improved grades, better mood, and fewer tardy arrivals. Despite this evidence, changing entrenched school schedules ⑤remains a slow and contentious process.

Limited-edition products are goods that ①are released in small quantities for a short period of time. Many companies use this strategy because scarcity naturally ②increases how much people desire an item. For instance, a sneaker company that releases only a few thousand pairs of a special design can generate long lines outside stores overnight, ③drawing attention from collectors worldwide. However, this psychological pressure can lead to purchases that ④are driven by fear rather than genuine need. Marketers, aware of this pattern, ⑤continues to design new limited releases because urgency reliably drives sales.

Sociologist Mark Granovetter introduced an idea that seems ①contradictory at first glance, known as the strength of weak ties. According to this theory, people who see each other only ②occasionally, called weak ties, often provide more valuable information than close friends or family members, who are considered strong ties. This happens because strong ties tend to share the same social circles and, therefore, already possess ③similar knowledge. Weak ties, in contrast, move within different networks, which allows them to introduce ideas or opportunities that would otherwise remain unknown. For example, a former classmate rarely contacted might mention a job opening unavailable through one's immediate circle. Social media platforms have made maintaining such connections remarkably ④harder, letting users keep hundreds of loose acquaintances active without frequent face-to-face meetings. Consequently, these platforms function as efficient channels through which weak ties continue delivering ⑤fresh opportunities that close relationships simply cannot offer.

Only a decade ago, translation apps produced sentences so awkward that users often laughed at the results. Today, many of these apps rely on neural networks that analyze entire sentences at once, capturing context instead of translating word by word. This shift has made everyday tasks such as reading a foreign menu or chatting with an overseas friend remarkably smooth. Even so, the technology still struggles with humor, sarcasm, and cultural nuance, so that _______________. For this reason, professional translators argue that these apps are best treated as a helpful starting point rather than a final, polished result.

Opening most camera apps today reveals a row of filters that can smooth skin, brighten eyes, and reshape a jawline before a photo is even taken. What began as a playful novelty has become a default setting for many users, subtly adjusting nearly every selfie posted online. Psychologists have grown concerned about a specific consequence of this shift: _______________. Some social media platforms have responded by labeling heavily edited photos or banning certain filters that alter body shape.

A smart thermostat that learns a family's daily rhythm can lower the temperature automatically before everyone wakes up cold, while smart lights that follow a resident's schedule no longer need to be switched on and off by hand. Sensors collect data about temperature, motion, and light throughout the home, and an algorithm gradually learns which settings match each household's actual habits. Yet convenience comes with a trade-off that many households overlook: _______________.

Adaptive learning apps promise something no traditional classroom can easily offer: a lesson plan that adjusts itself to each individual student in real time. (A) As a student answers practice questions, the app tracks which concepts are mastered and which remain shaky, then quietly reshuffles the next set of problems to target the weaker areas. (B) Early studies suggest that this personalized pacing can help struggling students catch up faster than a one-size-fits-all worksheet ever could. (C) However, critics caution that an app cannot replace the encouragement, humor, and flexibility a human teacher brings to a lesson.

Retailers rarely leave the shopping environment to chance. (A) For instance, cheerful background music and pleasant lighting are chosen specifically to keep shoppers relaxed and unhurried. (B) Every detail, from store layout to background music, is carefully designed to influence customer behavior. (C) As a result, customers often spend more time browsing and end up buying items they never intended to purchase.

주어진 문장: This is a significant shift from earlier generations, who often stuck with a single trusted brand for years. Generation Z, typically defined as those born between the late 1990s and early 2010s, approaches shopping quite differently from previous generations. ( ① ) Having grown up with smartphones and social media, they research products extensively online before making even small purchases. ( ② ) Unlike older generations, who often valued brand loyalty above all else, many members of Generation Z prioritize a company's values, switching brands easily if one no longer matches their beliefs. ( ③ ) They also tend to favor secondhand and resale platforms, viewing sustainability as an important factor rather than an afterthought. ( ④ ) Peer recommendations shared through short videos frequently carry more weight than traditional celebrity endorsements. ( ⑤ ) Businesses that fail to adapt to these preferences risk losing an entire generation of potential customers.

주어진 문장: Unlike a rigid vegan diet, this approach does not require anyone to give up their favorite dishes completely. A flexitarian is someone who mainly eats plant-based meals but occasionally includes meat or fish, unlike a strict vegetarian who avoids animal products entirely. ( ① ) This flexible diet has recently gained attention as a practical way to fight climate change, since raising livestock produces a significant portion of global greenhouse gas emissions. ( ② ) Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at trapping heat in the atmosphere. ( ③ ) By replacing just a few meat-based meals each week with vegetables, grains, or legumes, individuals can noticeably shrink their carbon footprint without giving up meat completely. ( ④ ) Nutritionists also emphasize that flexitarian eating is easier to maintain than full vegetarianism, because it allows flexibility rather than demanding absolute discipline. ( ⑤ ) Therefore, many environmental groups now promote flexitarianism as a realistic first step, believing that gradual change, rather than sudden restriction, is more likely to spread widely across society.
