As technology continues to reshape nearly every profession, the idea of finishing education after graduation ①has become outdated. Workers who once expected their initial training to last an entire career now find that skills can become obsolete within just a few years. Many professionals now take short online courses, attend workshops, or ②earn new certifications while continuing to work full-time. Companies that support this kind of continuous education often benefit as well, since employees ③bring fresh knowledge back into their daily tasks. Critics argue that constant learning can be exhausting and ④difficultly to balance with personal responsibilities. Nevertheless, most career experts insist that those who resist ongoing education risk ⑤falling behind their peers.

Self-driving technology is advancing rapidly, and its impact on the transportation industry ①is becoming increasingly visible. Companies are testing autonomous trucks ②that can travel long distances without human drivers, potentially transforming how goods move across countries. Millions of professional drivers worry about ③lose their jobs as automation spreads through the industry. Experts predict that certain driving jobs, particularly long-distance trucking, may ④shrink significantly within the next two decades. New roles are also emerging, including remote vehicle operators who monitor fleets of autonomous trucks and technicians ⑤who maintain the complex sensors these vehicles depend on.

Have you ever felt a ①boring class lasted forever while an exciting weekend disappeared in an instant? This common experience reflects what psychologists call the distortion of time perception: subjective time can differ from actual clock time. Researchers explain that people who focus intensely on an enjoyable activity process fewer separate moments, so time seems to pass ②slowly. In contrast, bored or anxious people pay ③closer attention to each moment, making time feel as though it is dragging. When people become deeply ④engaged in a task, they often lose track of time, unaware of how many minutes have passed. For example, athletes and musicians often say that hours felt like minutes while they were fully ⑤absorbed in performance.

Parents and coaches sometimes worry that heavy resistance training might damage the growth plates in a young athlete's bones, cartilage regions near the ends of long bones responsible for lengthening as a child develops. This concern kept strength training out of many youth programs for decades. However, extensive research over the past twenty years has found little evidence that properly supervised resistance training harms growth plates in healthy children, since _______________. Major pediatric and sports medicine organizations now generally agree that structured strength programs, when taught with correct form and appropriate weight, can safely improve bone density, coordination, and injury resistance in young athletes.

When Mina was a freshman, she often spent her allowance within a few days. Her older cousin told her about the marshmallow experiment, a famous study in which children could eat one marshmallow immediately or wait for two. Researchers found that children who waited longer showed better academic performance and self-control years later. This ___________ is known as delayed gratification. Inspired by the study, Mina began saving half of her allowance each week instead of spending it all on snacks.

Travelers who cross several time zones in a single flight often arrive feeling exhausted, foggy, and strangely out of sync with the local clock, a condition widely known as jet lag. The discomfort arises because the body's internal clock continues to run on the schedule of the departure city even after landing. Realigning this internal clock to a new time zone is not instantaneous; researchers estimate that the body typically needs about one day to adjust for every time zone crossed. Flying eastward tends to produce more severe symptoms than flying westward, because _______________. Exposure to natural light at the right moments after arrival can help speed up the adjustment, since light is the strongest external cue the internal clock uses to reset itself.

The clothing industry has become one of the largest contributors to environmental pollution worldwide. (A) Fast fashion refers to cheap, trendy clothing produced quickly and replaced almost as fast as it is bought. Because these garments are designed to be worn only a few times, huge amounts of fabric end up in landfills every year, and the dyeing process pollutes rivers near factories. (B) For example, some companies collect old clothes, break down the fibers, and weave them into new fabric, while others let customers rent outfits for special occasions rather than buying garments they will barely wear. These approaches keep resources circulating within the system longer, reducing demand for raw materials. Therefore, shifting from a throwaway habit toward a circular one may be essential for making the fashion industry sustainable. (C) In contrast, a growing number of brands are turning toward the circular economy, an economic model in which materials are reused, repaired, or recycled instead of being thrown away after a single use.

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.

The key distinction lies entirely in intensity: active recovery is not a second workout in disguise but a deliberately gentle session designed to support, rather than compete with, the body's underlying repair mechanisms. After an especially demanding training session, the instinct to collapse onto a couch and remain motionless is understandable, yet exercise physiologists increasingly recommend the opposite approach. ( ① ) Active recovery involves performing 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. ( ② ) This gentle activity keeps blood circulating through tired muscles, which appears to help clear metabolic byproducts that accumulate during hard exercise more efficiently than complete stillness does. ( ③ ) Some athletes worry that any movement at all will interfere with the repair process. ( ④ ) Research suggests, however, that truly light activity, kept well below the intensity of the original workout, does not meaningfully slow healing and may even reduce the perceived soreness that follows a hard session. ( ⑤ )

Its influence, in fact, can persist quietly long after any feeling of alertness has faded. Caffeine is the most widely consumed stimulant in the world, prized for its ability to sharpen focus and fight off fatigue within minutes of consumption. ( ① ) It works by blocking adenosine, a chemical that gradually builds up in the brain throughout the day and makes us feel increasingly sleepy the longer we stay awake. ( ② ) By occupying the receptors that adenosine would normally bind to, caffeine tricks the brain into feeling alert even when the body has accumulated significant sleep pressure. ( ③ ) The effects, however, last far longer than most people realize. Because caffeine can remain active in the bloodstream for five to six hours, a cup of coffee consumed in the late afternoon may still be interfering with the ability to fall asleep at midnight. ( ④ ) Even when people do not consciously notice difficulty falling asleep, caffeine has been shown to reduce the amount of deep, restorative sleep obtained later in the night. ( ⑤ ) For this reason, many sleep specialists advise avoiding caffeine after early afternoon.
