After a strenuous workout, muscle fibers experience thousands of microscopic tears, and the body immediately begins a repair process ① that ultimately makes the muscle stronger than it was before. This repair depends heavily on amino acids, the building blocks that protein ② supplying, 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 ③ declines 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 ④ burned for energy or stored as fat. For this reason, nutritionists generally advise ⑤ spreading moderate portions of protein evenly across several meals throughout the day rather than saving it all for one large post-workout meal.

Have you ever ①feel a boring 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 ②differ from actual clock time. Researchers explain that people who focus intensely on an enjoyable activity ③process fewer separate moments, so time seems to pass quickly. In contrast, bored or anxious people pay closer attention to each moment, ④making time feel as though it is dragging. When people become deeply engaged in a task, they often lose track of time, ⑤unaware of how many minutes have passed.

Imagine two factories making the same product: one in a country with ①**strict** carbon rules, and one in a country with almost none. The factory facing stricter rules often spends more, which can make its goods ②**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. Supporters argue that the system ③**protects** domestic industries and pushes foreign manufacturers toward cleaner methods. However, critics claim it unfairly ④**benefits** 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 ⑤**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.

In recent years, mental health experts have identified a distinct emotional response to environmental crisis, commonly called eco-anxiety. Eco-anxiety describes persistent worry, grief, or fear triggered by awareness of climate change and its consequences for the future. Although people of all ages can experience it, teenagers and young adults seem especially ①immune, since they anticipate living through decades of worsening conditions. Common symptoms include difficulty sleeping, a sense of ②hopelessness, and guilt over ordinary choices such as travel or diet. For example, some students report feeling ③paralyzed whenever they read alarming climate news, unable to focus on schoolwork or hobbies. However, experts emphasize that eco-anxiety is not a disorder to be eliminated but a ④natural reaction that can be channeled productively. Rather than avoiding the topic, young people are encouraged to join community projects, since taking constructive action tends to ⑤restore a sense of control and ease overwhelming distress.

Minji had tried for years to build a bedtime reading habit but always ①forgot once under the blanket. During summer, she found a method called habit stacking. It means attaching a new habit to an existing one so it acts as a reminder. Her existing habit was brushing her teeth every night, so she decided to place her book ②far from her toothbrush. After brushing her teeth, she would pick up the book, letting one action trigger the next. Within two weeks, opening the book after brushing felt almost ③automatic, requiring no conscious effort. She realized habit stacking worked best when the new habit was ④small and the existing habit was stable and predictable. By the end of summer, both habits felt like ⑤steady parts of her routine, requiring no reminders.

When a customer opens a company's website at midnight with a billing question, an actual employee is unlikely to be available, which is exactly the gap that customer service chatbots were built to fill. These programs can instantly answer common questions, track packages, and process simple refunds without making anyone wait on hold. Yet the technology has clear boundaries. When a customer's problem is unusual, emotionally charged, or simply does not fit the chatbot's script, _______________. Many companies have responded by designing chatbots to recognize their own limits, automatically transferring a frustrated customer to a human agent.

Sleep is not a single, uniform state but a cycle that alternates between two very different modes: REM (rapid eye movement) sleep and non-REM sleep. During non-REM sleep, especially its deepest stage, the brain waves slow down dramatically, the body temperature drops, and tissue repair and growth hormone release reach their peak. This is the period most closely associated with physical restoration. REM sleep, by contrast, brings rapid eye movements, near-total muscle paralysis, and brain activity that closely resembles wakefulness. Most vivid dreaming occurs during this stage, and researchers believe _______________. A healthy night typically cycles through both stages four or five times, with non-REM dominating the early hours and REM periods lengthening toward morning. Disrupting either stage, through frequent awakenings or alcohol use, can leave a person feeling unrested even after a full night in bed.

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.

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. (A) This gentle activity keeps blood circulating through tired muscles, which appears to help clear metabolic byproducts more efficiently than complete stillness does. (B) Some athletes worry that any movement at all will interfere with the repair process, but research suggests that truly light activity does not meaningfully slow healing. (C) 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.

Many students struggle not with lack of effort but with lack of structure when studying for exams. (A) Once colors are assigned, the student blocks specific hours of the day for each subject, following the same order as a printed timetable. (B) As a result, switching between subjects no longer feels confusing, because each color block signals exactly what should happen next. (C) One student solved this problem by giving each subject a distinct color on a printed weekly calendar before the semester began.
