After a strenuous workout, muscle fibers experience thousands of microscopic tears, and the body immediately begins a repair process ①that ultimately makes the muscle stronger than it was before. This repair depends heavily on amino acids, the building blocks that protein ②supplying, which is why sports scientists recommend consuming protein within a couple of hours after training. Waiting too long to eat can slow recovery, since a muscle's sensitivity to amino acids gradually ③declines once that window closes. Many athletes assume that eating an enormous quantity of protein in a single sitting will speed up this process, but the body can only use a limited amount at once; the rest is simply ④burned for energy or stored as fat. For this reason, nutritionists generally advise ⑤spreading moderate portions of protein evenly across several meals throughout the day rather than saving it all for one large post-workout meal.

As a result, the ads that appear on a person's screen often feel remarkably ①specific, sometimes referencing items browsed only minutes earlier. Supporters argue that this level of precision benefits consumers by ②reducing exposure to irrelevant advertisements and highlighting products they genuinely need. Some researchers have found that people who see highly personalized advertisements make impulsive purchases ③less frequently than those who see generic ones. Because these algorithms operate largely without public oversight, few consumers fully understand how their personal data shapes what they eventually buy. Greater ④transparency, many experts argue, would allow consumers to make more ⑤informed decisions about their own online behavior.

Many students assume that perfectionists work harder than everyone else, but psychologists describe a puzzling pattern called the perfectionism-procrastination cycle. This term describes how an intense fear of imperfect work causes people to ___________. Because perfectionists set impossibly high standards, they often feel anxious before they even begin, and the task feels overwhelming. They then postpone the work to avoid facing their own unrealistic expectations, even though delay only increases their stress later. For example, a student writing a research paper might spend hours reorganizing notes instead of composing a single sentence that feels good enough. Likewise, an employee facing an important report may check emails repeatedly rather than begin drafting, fearing an early attempt will seem inadequate. Ironically, this avoidance guarantees the very failure that perfectionists dread, since rushed, last-minute work rarely meets their own high standards.

Job seekers often assume that their closest friends will be the most helpful source of career advice. (A) In fact, studies show that a surprising number of job offers come through acquaintances met only briefly at conferences or previous workplaces. (B) However, close friends usually work in the same field or social circle, so their knowledge of new openings tends to overlap with what the job seeker already knows. (C) This is because such acquaintances belong to different professional circles, giving them access to information that never reaches close friends.

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. (A) 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. (B) 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. (C) 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.

주어진 문장: This flexibility, however, comes with a hidden cost that many workers overlook. Remote work has moved from a rare privilege to a common practice for millions of employees worldwide. ( ① ) Many companies that once required workers to commute daily now allow them to complete tasks from home. ( ② ) Supporters argue that remote work increases productivity, since employees avoid long commutes and distracting office environments. ( ③ ) It also allows companies to hire talented people regardless of where they live, widening the pool of candidates. ( ④ ) Critics, however, worry that remote work weakens teamwork and makes it harder for new employees to learn from experienced colleagues. ( ⑤ ) Without regular face-to-face interaction, some workers feel isolated and struggle to build strong professional relationships.

Some welcome the tool as a quick way to sketch ideas before refining them by hand. Feed an AI music program a mood, a tempo, and a rough genre, and within seconds it can generate a complete instrumental track, ready to be dropped under a video or used as background music for a small business. ( ① ) 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 rather than copying any single source directly. ( ② ) For independent creators who cannot afford a composer or expensive licensing fees, this has been a genuine breakthrough. ( ③ ) Professional musicians, however, remain divided. ( ④ ) Others worry that a flood of AI-generated background music could quietly push human composers out of smaller, lower-budget projects, the very jobs many musicians once relied on to build a career. ( 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.

Skipping this final stage, even when an athlete feels fully recovered, dramatically increases the risk of re-injury, because general strength does not automatically translate into the specific coordination that a particular sport demands. Recovering from a serious sports injury involves far more than simply waiting for torn tissue to heal; it requires a carefully structured program that gradually reintroduces stress to the affected area. ( ① ) Immediately after an injury, rest and gentle range-of-motion exercises help prevent stiffness without disturbing the healing tissue. ( ② ) As pain subsides, therapists introduce light resistance training, slowly rebuilding strength in muscles that have weakened from disuse. ( ③ ) Progressing too quickly at this stage is a common mistake, since tissue that appears healed on the surface may still be structurally fragile beneath it. ( ④ ) Only after strength and flexibility approach pre-injury levels do specialists introduce sport-specific drills that mimic the exact movements an athlete will face in competition. ( ⑤ )

주어진 문장: This difference in regulation can create an uneven playing field between the two factories, since one operates under far tighter restrictions than the other. Imagine two factories making the same product: one in a country with strict carbon rules, and one in a country with almost none. ( ① ) The factory facing stricter rules often spends more, which can make its goods pricier than those made elsewhere. ( ② ) 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. ( ③ ) Supporters argue that the system protects domestic industries and pushes foreign manufacturers toward cleaner methods. ( ④ ) However, critics claim it unfairly burdens developing countries, which often lack money to modernize factories quickly. ( ⑤ ) 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.
