After an especially demanding training session, the instinct to collapse onto a couch and remain motionless is understandable, yet exercise physiologists increasingly ①recommend the opposite approach. Active recovery involves ②to perform low-intensity movement, such as a light jog, an easy swim, or a gentle bike ride, on days following intense exertion rather than resting completely. This gentle activity keeps blood circulating through tired muscles, which ③appears to help clear metabolic byproducts that accumulate during hard exercise more efficiently than complete stillness does. Some athletes worry that any movement at all will interfere with the repair process, but research suggests that truly light activity ④does not meaningfully slow healing and may even reduce the perceived soreness that follows a hard session. The key distinction lies entirely in intensity: active recovery is not a second workout in disguise but a deliberately gentle session ⑤designed to support, rather than compete with, the body's underlying repair mechanisms.

Sociologist Mark Granovetter introduced an idea that seems contradictory at first glance, known as the strength of weak ties. According to this theory, people who see each other only occasionally, called weak ties, often ①provide 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 similar knowledge. Weak ties, in contrast, move within different networks, which ②allows 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 easier, letting users ③keeping hundreds of loose acquaintances active without frequent face-to-face meetings. Consequently, these platforms function as efficient channels through which weak ties continue ④delivering fresh opportunities that close relationships simply cannot ⑤offer.

Smartphones, tablets, and computer screens all emit a significant amount of blue light, a short-wavelength light that our eyes are especially sensitive to. During the day, exposure to blue light from the sun helps keep us ①drowsy and mentally sharp, which is generally beneficial. At night, however, the same wavelength can interfere with the body's natural preparation for sleep. Specialized cells in the retina detect blue light and send signals to the brain's internal clock, ②suppressing the release of melatonin, the hormone that signals it is time to rest. Studies have found that people who scroll through their phones in bed before sleeping take longer to fall asleep and experience ③lighter, more easily disrupted sleep than those who avoid screens. Some devices now offer a night mode that shifts the display toward ④warmer tones, reducing blue light output in the evening. While this feature may help slightly, sleep researchers generally recommend limiting screen use altogether in the hour before bedtime for the best ⑤results.

Many companies today advertise their products as environmentally friendly, yet not all of these claims are ①accurate. Consumers, who are increasingly ②concerned about climate change, often trust such claims without questioning them closely. As a result, they may pay ③higher prices for products that are no more sustainable than ordinary alternatives. Genuine environmental efforts, which usually require significant investment and long-term planning, are far more ④costly than simply changing a label. Therefore, governments should establish clear standards that require companies to prove their environmental claims with ⑤unverifiable data.

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.

FOMO refers to the anxious feeling that arises when people believe they are missing out on rewarding experiences that others are having. (A) For instance, a student who sees photos of a gathering she missed may feel sudden regret, even though the event is already over. (B) This feeling often leads people to check their phones compulsively, which makes it hard to focus on tasks at hand. (C) Such experiences are common among heavy social media users, who constantly compare their lives with the curated posts of others.

Consumers today increasingly consider more than just price when deciding what to buy. (A) For example, many shoppers now research a company's labor practices before purchasing its products. (B) This growing awareness reflects a shift toward what is often called value-based consumption. (C) As a result, companies face increasing pressure to operate more responsibly and transparently.

Melatonin is a hormone produced by a small gland deep within the brain, and its release follows a remarkably predictable daily pattern. (A) This rhythm is controlled primarily by light: specialized cells in the eye detect brightness and send signals that either permit or suppress melatonin production, which is why exposure to bright screens late at night can delay its release and make falling asleep more difficult. (B) Levels stay low throughout the bright hours of the day, begin rising in the evening as darkness falls, peak in the middle of the night, and then decline again as morning approaches. (C) Unlike some hormones that directly cause the body to perform a task, melatonin does not force sleep to occur; instead, it signals to the rest of the body that night has arrived, preparing various systems to shift into a lower-energy state. Because of this signaling role, taking melatonin supplements at the wrong time can shift a person's internal clock in the opposite direction from what was intended.

The filter bubble does not stay limited to search results; it gradually shapes nearly every aspect of a person's online experience. (A) For instance, a user who frequently watches cooking videos may find that recommended content across multiple platforms becomes overwhelmingly food-related within just a few days. (B) As this pattern continues, the same user may rarely encounter unrelated topics, such as political news or scientific discoveries, unless algorithms judge them relevant. (C) Streaming services, shopping websites, and news aggregators all rely on similar algorithms that learn from previous clicks and viewing habits.

Sleep debt refers to the cumulative gap between the amount of sleep a person needs and the amount they actually get. (A) Unlike a financial debt, however, this deficit cannot simply be repaid with a single long weekend of rest. (B) When someone loses two hours of sleep every night for a week, the body does not treat the shortage as fourteen separate small losses; instead, it accumulates the deficit, and the resulting impairment in attention and mood can resemble that of a person who has been awake for an entire night. (C) Researchers have found that even modest, chronic sleep restriction gradually impairs reaction time and decision-making, often without the affected person noticing the decline. This is because subjective feelings of tiredness tend to plateau after a few days, even as objective performance keeps deteriorating. Consequently, people frequently underestimate how much sleep debt they are carrying until a demanding task suddenly exposes the accumulated cost.
