When Mina was a freshman, she often ①spent her allowance within a few days. Her older cousin told her about the marshmallow experiment, a famous study ②in which children could eat one marshmallow immediately or wait for two. Researchers found that children who waited longer ③shown better academic performance and self-control years later. Inspired by the study, Mina began ④saving half of her allowance each week instead of spending it all on snacks. After three months, however, she had saved enough to buy a bicycle she had ⑤wanted for over a year.

Many companies now advertise themselves as environmentally responsible, yet a growing number of these claims ①turn out to be misleading. This practice, known as greenwashing, ②occurs when a business spends more effort marketing its products as eco-friendly than actually reducing environmental harm. A company might launch a recycled-packaging line while ③continuing to pollute rivers through its main factories, creating a false impression of genuine change. Such tactics deceive well-intentioned consumers who wish to shop responsibly but ④lacks the tools to verify corporate claims. In contrast, truly sustainable businesses publish detailed, independently verified data about their emissions and supply chains, ⑤allowing outsiders to check their progress.

Social psychologists describe a phenomenon called the bystander effect, in which individuals become less likely ①helping a victim as the number of witnesses increases. Each observer assumes someone else will step in, and this diffusion of responsibility leaves no one ②willing to act. Cyberbullying magnifies this problem, since a single humiliating post can be witnessed by thousands of people ③scattered across the internet rather than a few standing nearby. Anonymity intensifies the effect further, allowing silent observers ④to scroll past cruel comments without feeling accountable for their inaction. Some bystanders even worry that intervening publicly might make them the bully's next target, so they choose ⑤to remain silent instead.

Choice architecture refers to how decisions are ①designed. It determines which option is automatically selected unless a person chooses otherwise, ②known as the default option. Research consistently shows that people tend to stick with whatever is already set, even when changing it takes only seconds. Organ donation is a well-known example. Countries ③which citizens are automatically registered as donors unless they opt out show much higher donation rates than opt-in countries. Retirement savings programs show a similar pattern, since employees ④automatically enrolled in a pension plan rarely cancel it. Voluntary sign-ups, in contrast, often delay indefinitely. Critics argue that default options can be manipulated to benefit companies, so transparency about how defaults are chosen becomes essential, and supporters insist it should be designed ⑤to support people's long-term interests.

Automation is transforming labor markets more quickly than economists predicted only a decade ago. Factories once staffed by hundreds of workers now rely on robotic arms ①that assemble products with remarkable precision. Warehouses use automated systems ②to sort and deliver packages within a few hours. This shift does not simply eliminate jobs; it also creates roles that ③never exists before. Technicians who maintain robotic equipment are now in high demand, and engineers who design efficient systems ④are highly valued. Policymakers argue that retraining programs ⑤are essential to help displaced workers move into emerging fields.

Melatonin is a hormone ① produced by a small gland deep within the brain, and its release follows a remarkably predictable daily pattern. Levels stay low throughout the bright hours of the day, ② begin rising in the evening as darkness falls, peak in the middle of the night, and then decline again as morning approaches. This rhythm is controlled primarily by light: specialized cells in the eye detect brightness and send signals that either permit or ③ suppress melatonin production, which is why exposure to bright screens late at night can delay its release and make falling asleep more difficult. Unlike some hormones that directly cause the body to perform a task, melatonin does not force sleep to occur; instead, it signals to the rest of the body that night has arrived, ④ preparing various systems to shift into a lower-energy state. Because of this signaling role, taking melatonin supplements at the wrong time can shift a person's internal clock in the opposite direction from what was ⑤ intending.

Behavioral economists use the term temporal discounting to describe how people ①undervalue future rewards simply because those rewards are not immediate. This tendency explains why a student might choose to watch videos tonight rather than study for an exam that remains several weeks away, even though studying offers a ②smaller long-term benefit. A distant reward, no matter how valuable, feels psychologically smaller than a small reward available right now. This bias contributes to procrastination, since future consequences rarely feel ③urgent enough to motivate immediate action. To counter this tendency, students should ④convert distant goals into smaller, near-term milestones that feel more emotionally real. Setting weekly checkpoints rather than a final deadline can make future benefits feel ⑤closer and more concrete.

Imagine a cafeteria where a healthy salad sits at eye level while fried snacks rest on a low shelf. Nobody is forbidden from choosing the snacks, yet most people quietly pick the salad instead. This simple technique illustrates a nudge, a concept from behavioral economics _______________. Companies and governments increasingly apply nudges to encourage sustainable consumption. For example, some hotels print reminders on towels stating that most guests reuse them, which persuades new guests to do the same and save water. Similarly, energy bills that compare a household's usage with that of efficient neighbors often lead people to reduce electricity use. Unlike strict regulations or heavy taxes, nudges rely on subtle changes in design rather than force. Critics argue nudges alone cannot solve large environmental problems, but combined with stronger policies, they can meaningfully shift everyday habits toward sustainability.

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. (A) REM sleep, by contrast, brings rapid eye movements and brain activity resembling wakefulness, and is believed to help consolidate memories and process emotions. (B) A healthy night cycles through both stages several times, and disrupting either one can leave a person feeling unrested despite a full night in bed. (C) During non-REM sleep, particularly its deepest stage, the brain waves slow dramatically and the body focuses on physical repair.

주어진 문장: This fear of missing out, often shortened to FOMO, drives many shoppers to act faster than they normally would. Limited-edition products are goods that are released in small quantities for a short period of time. ( ① ) Many companies use this strategy because scarcity naturally increases how much people desire an item. ( ② ) When consumers believe that a product will disappear soon, they often feel pressured to buy it immediately rather than wait. ( ③ ) For instance, a sneaker company that releases only a few thousand pairs of a special design can generate long lines outside stores overnight. ( ④ ) However, this psychological pressure can lead to purchases that are driven by fear rather than genuine need. ( ⑤ ) As a result, some shoppers later regret spending money on products they rarely use afterward.
