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 quietly ①encourage weight gain. Two hormones in particular play opposing roles in regulating appetite: leptin signals fullness to the brain, while ghrelin ②stimulate the sensation of hunger. Studies show that sleep deprivation lowers leptin levels while raising ghrelin levels, so a tired body ends up ③feeling hungrier 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 responsive to insulin and ④leaving 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 ⑤raise the risk of developing type 2 diabetes.

The gig economy, in which people take on short-term or freelance jobs instead of full-time positions, has grown rapidly over the past decade. This model offers clear advantages: workers can choose when and how much they work, and businesses can hire help only when they actually need it. For many young people entering the job market, gig work provides valuable flexibility that traditional employment rarely allows. However, gig workers often ___________, which full-time employees typically receive. Because their income can fluctuate sharply from month to month, many gig workers struggle to plan their finances confidently.

Internet activist Eli Pariser introduced the term filter bubble to describe a phenomenon created by online algorithms. Social media platforms and search engines constantly track which links users click and how long they linger on certain posts. Based on this data, algorithms predict what each individual is most likely to enjoy and quietly prioritize similar content in future results. As a result, two people who type the same search query can receive strikingly different results, each tailored to personal history. This automatic filtering happens silently, without users ever deciding to limit what they see. Consequently, many people gradually lose access to viewpoints that challenge their existing beliefs, even though they never intended to avoid them. Pariser warned that this invisible curation could weaken democratic debate by narrowing public discussion. Therefore, some experts argue that platforms should reveal how content is filtered, _______________.

Feed an AI music program a mood, a tempo, and a rough genre, and within seconds it can generate a complete instrumental track. The software has studied thousands of existing songs, learning which chord progressions and rhythms tend to sound pleasant together, and it recombines these patterns into something new. For independent creators who cannot afford a composer, this has been a genuine breakthrough. Professional musicians, however, remain divided. Some welcome the tool as a quick way to sketch ideas before refining them by hand, while others worry that _______________.

Many people struggling to fall asleep in noisy environments turn to white noise machines, devices that emit a steady, uniform sound covering a broad range of frequencies. (A) Without this masking effect, an abrupt change in sound is far more likely to trigger a brief awakening, even if the sleeper does not consciously remember it the next morning. (B) The appeal lies in a phenomenon called auditory masking, in which a constant background sound makes sudden noises, such as a slamming door, less noticeable to the sleeping brain. (C) However, researchers caution that the benefit depends heavily on volume and consistency, since noise that is too loud or unpredictable can itself become a source of disruption rather than a remedy.

Sleep hygiene refers to a set of simple daily habits that help the body prepare for consistent, restorative rest. (A) They also advise reserving the bedroom for sleep alone, since using the bed to study, scroll through a phone, or watch videos teaches the brain to associate that space with wakeful activity rather than rest. (B) Physical environment matters as well: a cool, dark, and quiet room tends to produce deeper sleep than one that is warm, bright, or noisy. None of these individual habits guarantees a good night's sleep on its own, but together they form a routine that gradually trains the body to expect and enter sleep more easily, much the way a consistent set of cues trains an athlete's body to perform at a certain time each day. (C) Experts commonly recommend going to bed and waking up at the same time every day, even on weekends, because an irregular schedule confuses the body's internal clock and makes it harder to fall asleep on demand.

Imagine two factories making the same product: one in a country with strict carbon rules, and one in a country with almost none. (A) However, critics claim it unfairly burdens developing countries, which often lack money to modernize factories quickly. For example, a small exporter in a poorer nation might struggle to pay the added charge, though it contributes little to global emissions. Still, if wealthier nations pair the policy with technical support, it could become a genuinely fair tool for cutting emissions worldwide. (B) Supporters argue that the system protects domestic industries and pushes foreign manufacturers toward cleaner methods. (C) The factory facing stricter rules often spends more, which can make its goods pricier than those made elsewhere. To fix this imbalance, some governments have introduced the carbon border adjustment mechanism, a policy charging imported goods a fee based on how much carbon was released while producing them.

주어진 문장: Once audiences discover that a recommendation was insincere, they rarely trust that influencer again. Influencer marketing has become one of the most powerful tools that companies use to reach young consumers. ( ① ) Unlike traditional advertisements, which often feel distant and impersonal, posts created by influencers seem more like advice from a trusted friend. ( ② ) This sense of closeness, built through years of sharing daily life online, makes followers more willing to trust product recommendations than ordinary commercials. ( ③ ) However, this trust can be exploited when influencers promote products they have never actually tried. ( ④ ) As a result, several countries now require influencers to clearly disclose paid partnerships before posting sponsored content. ( ⑤ ) In the end, influencer marketing works best when it stays grounded in authenticity rather than mere popularity.

Because the airway narrows gradually rather than closing all at once, the severity of each episode can vary widely. Sleep apnea is a disorder in which breathing repeatedly stops and restarts during sleep, often because the muscles at the back of the throat relax too much and block the airway. ( ① ) Each pause can last from a few seconds to over a minute, and it may occur dozens of times in a single night without the sleeper ever waking up fully. ( ② ) Because these interruptions rarely produce a clear memory the next morning, many people remain unaware that anything is wrong, even as chronic fatigue, headaches, and irritability build up over months. ( ③ ) Doctors therefore rely less on a patient's own account of the night and more on objective measurements, such as overnight oxygen levels and airflow patterns recorded in a sleep laboratory. ( ④ ) Left untreated, the disorder has been linked to serious long-term risks, including high blood pressure and heart disease, which makes an accurate diagnosis far more urgent than its subtle nighttime symptoms might suggest. ( ⑤ )
