Elite athletes often perform in front of enormous crowds with championships, contracts, and years of training riding on a single moment, and the psychological weight of that pressure can ①undermine skills that feel automatic in practice. Sports psychologists explain that intense anxiety narrows attention and disrupts the smooth, unconscious execution of well-learned movements, a phenomenon sometimes ②called choking under pressure. Rather than trying to eliminate nervousness entirely, which research suggests ③are nearly impossible, many trainers now teach athletes ④to reinterpret the physical symptoms of anxiety, such as a racing heart, as signs of readiness rather than danger. Over time, repeated exposure to high-pressure situations in practice, deliberately ⑤simulated to resemble real competition, allows athletes to build tolerance the same way their muscles adapt to physical training.

When people consistently sleep too little, the body's hormonal balance shifts in ways that can ①quietly encourage weight gain. Two hormones in particular play ②opposing roles in regulating appetite: leptin signals fullness to the brain, while ghrelin stimulates the sensation of hunger. Studies show that sleep deprivation lowers leptin levels while raising ghrelin levels, so a tired body ends up feeling ③fuller than it actually needs to be, even after a normal-sized meal. At the same time, insufficient sleep interferes with how efficiently the body processes glucose, making cells less ④responsive to insulin and leaving more sugar circulating in the bloodstream than usual. Over months or years, this combination of increased appetite and reduced insulin sensitivity can contribute to steady weight gain and raise the risk of developing type 2 diabetes. Because these effects build up so ⑤gradually, many people never connect their shifting eating habits or worsening blood sugar to something as ordinary as a few lost hours of sleep each night.

For decades, athletes were taught to stretch a muscle and hold the position before any competition, believing that this practice alone would ①prevent injury. Recent research, however, has complicated that assumption considerably. Static stretching, in which a muscle is held at its longest length for an extended period, can actually ②reduce the muscle's ability to generate explosive force immediately afterward, which is troubling for sprinters or jumpers who need maximum power right away. Dynamic stretching, which involves controlled, repeated movement through a joint's full range of motion, appears to ③prepare muscles for activity without this temporary weakening effect. As a result, many coaches now recommend ④saving static stretching for after a workout, when it may help restore muscle length and reduce soreness, while reserving dynamic movements for the warm-up period before intense effort begins. The right technique, in other words, depends heavily on ⑤chance.

Some critics ①dismiss this approach as impractical, arguing 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 ②sacrifice; it often means buying fewer, higher-quality items rather than accumulating cheap goods that wear out quickly. This shift also encourages companies to improve their practices, since consumer demand increasingly rewards ③transparency and responsibility. For example, a clothing brand that openly shares its supply chain information may attract ④disloyal customers willing to pay slightly more. Ultimately, value-based consumption suggests that spending money is not merely an economic act but also a ⑤reflection of personal values.

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 alert 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, which results in _______________. Studies have found that people who scroll through their phones in bed before sleeping take longer to fall asleep and experience lighter, more easily disrupted sleep than those who avoid screens. Some devices now offer a night mode that shifts the display toward warmer 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 results.

A short nap taken in the early afternoon, often called a power nap, can noticeably sharpen attention and mood without leaving a person groggy afterward. The key lies in timing: naps limited to roughly twenty minutes allow the brain to pass through the lightest stages of sleep while avoiding the deeper stages associated with slow-wave activity. If a nap extends much beyond that window, _______________. Laboratory studies comparing napping and non-napping groups have repeatedly shown that a brief nap improves reaction time and short-term memory almost as effectively as a full night of extra rest. Interestingly, the benefit appears strongest when the nap occurs several hours after waking, since this is when the body's natural dip in alertness makes rest most effective. For this reason, many workplaces now designate quiet rooms where employees can recharge briefly during the day.

The rapid rise of the gig economy has led researchers to examine both its opportunities and its risks. (A) In addition, because their income depends heavily on the number of tasks completed, many gig workers find it difficult to save money consistently. (B) On the positive side, gig platforms allow workers to set their own schedules and take on projects that match their skills. (C) Yet this freedom comes at a price, since most gig workers are not entitled to employer-provided benefits like health insurance.

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.

Climate change is not only a scientific and political issue but also an emotional one for many people today. (A) Teenagers and young adults tend to feel it most intensely, since they expect to live through many more decades of a changing climate than older generations do. (B) This emotional dimension, known as eco-anxiety, refers to persistent worry, grief, or fear that stems from awareness of climate change and its future consequences. (C) Fortunately, channeling this anxiety into constructive action, such as joining community environmental projects, can help restore a sense of control rather than deepen despair.

Every brand has a history, but not every brand knows how to tell it well. (A) For example, a small shoe company once shared the story of its founder's grandfather, who had repaired shoes for workers in need. (B) Consequently, other companies began investing in storytelling as a core part of their marketing strategy. (C) Stories like this create emotional connections that plain advertisements rarely achieve on their own.
