As millions of people now earn income through delivery apps and ride-hailing platforms, questions about their legal status ①have become increasingly urgent. Most platform workers are classified as independent contractors rather than employees, ②which means they are not entitled to minimum wage guarantees or paid sick leave. Companies favor this arrangement because it allows them ③to avoid the costs associated with hiring full employees. Worker advocates, however, argue that many platform workers ④depend on these jobs as their primary source of income. Several countries have recently begun reconsidering their labor laws, ⑤proposed new categories that would grant workers some protections.

Online advertising algorithms analyze enormous amounts of user data ①to determine which products a person is most likely to purchase. Every click, search, and pause while scrolling provides information that these systems use ②to refine future advertisements. Supporters argue that this level of precision benefits consumers by ③reducing exposure to irrelevant advertisements and highlighting products they genuinely need. Critics, however, worry that constant exposure to tailored ads can encourage unnecessary spending, since algorithms ④is specifically designed to identify and exploit individual weaknesses. Greater transparency, many experts argue, would allow consumers ⑤to make more informed decisions about their own online behavior.

Value-based consumption refers to the practice of spending money on products or experiences ①that align with a person's personal beliefs, even if cheaper alternatives exist. Some critics dismiss this approach as impractical, ②arguing that most people cannot afford to prioritize ethics over affordability in daily life. However, supporters point out that value-based spending does not require constant sacrifice; it often means ③buying fewer, higher-quality items rather than accumulating cheap goods that wear out quickly. This shift also encourages companies ④improve their practices, since consumer demand increasingly rewards transparency and responsibility. For example, a clothing brand that openly shares its supply chain information may attract loyal customers ⑤willing to pay slightly more.

Before making a purchase, most online shoppers now read reviews written by previous customers rather than relying solely on advertisements. These reviews, posted by people who have no financial connection to the seller, often seem more ①trustworthy than promotional claims. Research shows that products with a large number of positive reviews sell significantly ②more than those with few or no reviews at all. However, fake reviews written by paid writers or even automated programs have become a serious problem, ③undermining consumer trust. Platforms that fail to detect these fraudulent posts risk ④gaining credibility with their users, who expect authentic opinions when making decisions. Ultimately, the power of online reviews depends entirely on their perceived ⑤honesty.

In recent years, mental health experts have identified a distinct emotional response to environmental crisis, commonly called eco-anxiety. Eco-anxiety describes persistent worry, grief, or fear triggered by awareness of climate change and its consequences for the future. Although people of all ages can experience it, teenagers and young adults seem especially ①immune, since they anticipate living through decades of worsening conditions. Common symptoms include difficulty sleeping, a sense of ②hopelessness, and guilt over ordinary choices such as travel or diet. For example, some students report feeling ③paralyzed whenever they read alarming climate news, unable to focus on schoolwork or hobbies. However, experts emphasize that eco-anxiety is not a disorder to be eliminated but a ④natural reaction that can be channeled productively. Rather than avoiding the topic, young people are encouraged to join community projects, since taking constructive action tends to ⑤restore a sense of control and ease overwhelming distress.

Limited-edition products are goods that are released in small quantities for a short period of time. Many companies use this strategy because ___________. When consumers believe that a product will disappear soon, they often feel pressured to buy it immediately rather than wait. For instance, a sneaker company that releases only a few thousand pairs of a special design can generate long lines outside stores overnight. This excitement is intensified by social media, where people proudly share photos of items that others could not obtain. However, this psychological pressure can lead to purchases that are driven by fear rather than genuine need. As a result, some shoppers later regret spending money on products they rarely use afterward.

To compensate for their carbon emissions, many individuals and companies now purchase carbon offsets, financial credits that fund projects such as planting trees or building renewable energy plants. The idea is appealing: paying for an equivalent amount of carbon to be absorbed elsewhere should cancel out the harm caused by activities like flying. However, critics argue that this system often functions as _______________. For example, a newly planted forest may take decades to absorb the promised carbon, and it could later burn down or be cut, erasing any benefit. Moreover, some offset projects would have happened anyway, meaning the credits fund nothing truly additional. Therefore, relying heavily on offsets allows businesses to maintain harmful practices while appearing responsible. Experts insist that offsetting should complement, not replace, direct reductions in fossil fuel use if the strategy is to remain credible.

Years ago, a small shoe company struggled to compete with larger, well-funded rivals in the market. Its products were solid, but customers rarely remembered the brand after a single purchase. One day, the founder decided to share the story behind the company: how her grandfather had once repaired shoes for factory workers who could not afford new pairs. She began printing this story on every shoebox and posting it across social media. Surprisingly, customers started responding not just to the shoes themselves but to the values the story represented. Sales slowly increased as people felt they were supporting something meaningful rather than simply buying a product. Other companies noticed this shift and began crafting their own narratives, hoping to create similar emotional connections. Eventually, the founder realized that ___________.

Even a modest level of dehydration, as little as two percent of body weight lost through sweat, can measurably reduce an athlete's endurance and cognitive sharpness during competition. (A) Dehydration also impairs the body's ability to regulate its own temperature, since sweating is the primary mechanism for releasing excess heat during intense exercise. (B) As fluid levels drop, blood volume decreases, forcing the heart to work harder to deliver the same amount of oxygen to working muscles, which accelerates fatigue. (C) Athletes competing in hot, humid conditions therefore face a particularly difficult balance, since sweating heavily to stay cool simultaneously depletes the very fluids needed to sustain performance.

This connection is not merely correlational; sleep appears to directly supply the raw materials the immune system needs. When the body fights off an infection, the immune system relies heavily on adequate sleep to function effectively. ( ① ) During deep sleep, the body produces and releases cytokines, proteins that help regulate immune responses and coordinate the fight against harmful invaders such as viruses and bacteria. ( ② ) People who consistently sleep fewer than six hours a night show measurably weaker antibody responses after vaccination compared with those who sleep seven or eight hours, suggesting that sleep loss can blunt the immune system's ability to build lasting protection. ( ③ ) Chronic sleep deprivation also appears to promote low-grade inflammation throughout the body, a state that, over time, has been linked to a higher risk of heart disease and other chronic conditions. ( ④ ) Rather than being a passive state in which the body simply rests, sleep functions as an active period during which the immune system repairs itself and prepares for future threats. ( ⑤ ) This is why doctors often recommend extra sleep, not just medication, when someone is fighting an illness.
