Exercise does far more than strengthen muscles and the heart; it also produces measurable changes within the brain itself. During sustained physical activity, the body ①releases a protein called brain-derived neurotrophic factor, which supports the growth of new neurons and ②strengthens connections between existing ones, particularly in regions associated with memory and learning. Studies comparing physically active students to sedentary peers have repeatedly found that the active group ③performing better on tests of attention and problem-solving, even when the exercise session ends well before the test begins. Researchers believe that exercise increases blood flow to the brain, ④delivering oxygen and nutrients more efficiently, while also reducing levels of stress hormones that can interfere with clear thinking. These findings have encouraged some schools ⑤to schedule exercise before demanding academic classes.

As consumers become more aware of global social and environmental issues, many now expect companies ①to take responsibility beyond simply selling products. This expectation has given rise to ethical consumption, in which shoppers consider factors such as fair wages, humane treatment of animals, and environmental sustainability before making purchases. Companies that ignore these concerns risk public backlash, especially when unethical practices are exposed through investigative journalism or social media. Some corporations have responded by publishing detailed sustainability reports, though critics ②questions whether these documents reflect genuine change or merely serve as public relations tools. Real accountability, according to many experts, ③requires independent verification rather than self-reported claims that cannot be easily checked. Consumers, for their part, must also ④remain vigilant, since a company's marketing language does not always ⑤match its actual practices.

Rather than replacing human creativity outright, many artists, writers, and filmmakers have begun ①treating AI tools as an unusual kind of collaborator, one that generates dozens of rough options in the time it would take a person to sketch just one. A novelist might ask an AI model for ten possible opening lines and then discard nine, ②keeping only the phrase that sparks an idea worth developing further. A film composer might use an AI system to generate a rough melody, then ③rework it entirely by hand until it fits the emotional tone of a specific scene. What makes this collaboration work, according to many creators, is that the human remains firmly in charge of judgment and taste, ④using the AI's output as raw material rather than a finished product. Critics counter that this framing can understate the risk, since even a first draft ultimately ⑤shape everything that follows it.

In recent years, mental health experts have ①identified a distinct emotional response to environmental crisis, commonly called eco-anxiety. Eco-anxiety describes persistent worry, grief, or fear ②triggered 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 vulnerable, since they ③anticipate living through decades of worsening conditions. Common symptoms include difficulty sleeping, a sense of hopelessness, and guilt over ordinary choices such as travel or diet. For example, some students report ④feeling paralyzed 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 natural 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 ⑤restoring a sense of control and ease overwhelming distress.

Sociologist Mark Granovetter introduced an idea that seems contradictory at first glance, known as the strength of weak ties. According to this theory, people who see each other only occasionally, called weak ties, often provide more valuable information than close friends or family members, who are considered strong ties. This happens because strong ties tend to share the same social circles and, therefore, already possess similar knowledge. Weak ties, in contrast, move within different networks, which allows them to introduce ideas or opportunities that would otherwise remain unknown. For example, a former classmate rarely contacted might mention a job opening unavailable through one's immediate circle. Social media platforms have made maintaining such connections remarkably easier, letting users keep hundreds of loose acquaintances active without frequent face-to-face meetings. Consequently, these platforms _______________.

Limited-edition products are goods that are released in small quantities for a short period of time. Many companies use this strategy because ___________. When consumers believe that a product will disappear soon, they often feel pressured to buy it immediately rather than wait. For instance, a sneaker company that releases only a few thousand pairs of a special design can generate long lines outside stores overnight. This excitement is intensified by social media, where people proudly share photos of items that others could not obtain. However, this psychological pressure can lead to purchases that are driven by fear rather than genuine need. As a result, some shoppers later regret spending money on products they rarely use afterward.

Habit researchers often note that people overestimate the role of motivation in daily routines. (A) As a result, they frequently give up soon after starting, blaming themselves for lacking discipline. (B) In contrast, Fogg's framework suggests that shrinking the task itself is more effective than boosting motivation. (C) Because motivation naturally rises and falls, relying on it alone often leads to inconsistent effort.

Psychologists have long debated why some people find it easier than others to wait for future rewards. (A) For example, children who distracted themselves by singing or looking away were far more successful at waiting. (B) One explanation involves specific strategies, such as focusing attention away from the tempting object. (C) In the original marshmallow studies, researchers observed that success depended heavily on how children managed their attention.

주어진 문장: This is why a ten-minute wait for test results can feel far longer than a ten-minute conversation with a close friend. Have you ever felt a boring class lasted forever while an exciting weekend disappeared in an instant? ( ① ) This common experience reflects what psychologists call the distortion of time perception: subjective time can differ from actual clock time. ( ② ) Researchers explain that people who focus intensely on an enjoyable activity process fewer separate moments, so time seems to pass quickly. ( ③ ) In contrast, bored or anxious people pay closer attention to each moment, making time feel as though it is dragging. ( ④ ) When people become deeply engaged 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 absorbed in performance. Meanwhile, students waiting anxiously for exam results describe the same few minutes as unbearably slow. ( ⑤ ) Understanding this distortion helps explain why identical time intervals can feel very different depending on mental state.

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 )
