Caffeine is the most widely consumed stimulant in the world, ①prizing for its ability to sharpen focus and fight off fatigue within minutes of consumption. It works by blocking adenosine, a chemical that gradually builds up in the brain throughout the day and ②makes us feel increasingly sleepy the longer we stay awake. By occupying the receptors that adenosine would normally bind to, caffeine tricks the brain into ③feeling alert even when the body has accumulated significant sleep pressure. 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 ④consumed in the late afternoon may still be interfering with the ability to fall asleep at midnight. Even when people do not consciously notice difficulty falling asleep, caffeine has been shown ⑤to reduce the amount of deep, restorative sleep obtained later in the night.

As nudging has moved from academic theory into widespread practice, a persistent ethical question has accompanied its rise: at what point ①does subtly guiding behavior for someone's own benefit shade into manipulation that undermines their capacity for autonomous choice? Proponents typically distinguish nudges from manipulation by pointing to transparency and reversibility, arguing that a legitimate nudge ②operate openly, can be easily resisted by anyone who wishes to opt out, and ultimately serves the interests of the person being nudged rather than the interests of whoever designed the intervention. Critics counter that this distinction often collapses in practice, since many effective nudges work precisely because they ③exploit cognitive processes operating below conscious awareness, meaning that the person being influenced may never fully register that a nudge is even occurring. A supermarket that arranges healthier foods at eye level, for instance, differs only in the direction of its influence, not in its underlying mechanism, from a supermarket that ④arranges the most profitable items at eye level. This tension suggests that the ethical status of a nudge cannot be evaluated by examining its psychological mechanism alone; instead, it must be judged according to the intentions of the party who ⑤designs it and the outcome that design is intended to produce.

As artificial intelligence grows more capable of performing tasks once considered exclusively human, many people wonder which skills will remain valuable in the future. AI can now analyze data, generate text, and even diagnose certain medical conditions with ①impressive accuracy. However, most researchers argue that AI still ②struggles with tasks requiring genuine empathy, ethical judgment, and creative problem-solving in unfamiliar situations. A machine can recommend a treatment plan based on statistics, for instance, but it can ③easily comfort a frightened patient the way a compassionate nurse can. Similarly, AI can generate countless design variations, yet it ④lacks the lived experience that allows humans to judge which idea truly resonates with people. For this reason, educators increasingly emphasize skills such as collaboration and emotional intelligence, arguing that these human capabilities will become more ⑤valuable as automation spreads.

Jiho had always assumed he would join a large corporation after graduation, just as his parents expected. During his final year of university, however, he joined a small student team building an app that connected local farmers directly with restaurants. What started as a class project gradually turned into something more ①serious, as several restaurants began placing regular orders through their prototype. Jiho and his teammates decided to ②abandon their idea and instead spend a year developing it further, despite warnings from relatives who considered the plan too risky. They worked from a cramped apartment, surviving on ③limited savings while learning skills ranging from coding to negotiating with suppliers. After nearly failing twice, the team secured a small investment that allowed them to hire their first ④employee. Looking back, Jiho believes that the uncertainty of startup life taught him far more about problem-solving than any traditional job could have ⑤offered.

Artificial intelligence has begun to play a surprising role in creative industries once thought to be uniquely human. Some artists welcome this technology, using AI tools to explore new styles or overcome creative blocks that once took weeks to resolve. Others, however, argue that AI-generated art lacks the emotional depth that comes from genuine human experience. Despite this debate, most experts agree that AI is unlikely to fully replace artists anytime soon. Instead, it ___________, helping creators experiment faster while leaving final artistic decisions to humans.

Among the many tools available to those who design choice environments, few are as quietly powerful as the default option, the alternative that takes effect automatically unless a person actively selects something else. Because changing a default requires deliberate effort, many individuals simply accept whatever arrangement has been preselected for them. Designers of public policy and digital platforms alike have consequently come to recognize that setting a thoughtful default can achieve outcomes that ___________ often struggle to accomplish through persuasion or financial incentive alone.

Riding a bicycle is a great way to stay active during summer vacation, but ___________. Before you ride, check that your tires are properly inflated and your brakes are working well. Wearing a helmet is essential, since it can prevent serious head injuries in an accident.

Years ago, a small shoe company struggled to compete with larger, well-funded rivals in the market. Its products were solid, but customers rarely remembered the brand after a single purchase. One day, the founder decided to share the story behind the company: how her grandfather had once repaired shoes for factory workers who could not afford new pairs. She began printing this story on every shoebox and posting it across social media. Surprisingly, customers started responding not just to the shoes themselves but to the values the story represented. Sales slowly increased as people felt they were supporting something meaningful rather than simply buying a product. Other companies noticed this shift and began crafting their own narratives, hoping to create similar emotional connections. Eventually, the founder realized that ___________.

Psychologists point to three main reasons why new year's resolutions often fail within a few days. (A) Second, many resolutions are unrealistic from the start, since people set goals that are far too difficult to reach in a short time. (B) First, willpower works like a muscle that becomes tired after being used too much, so people run out of self-control quickly. (C) Third, most resolutions do not offer any immediate reward, which makes it hard to stay motivated without seeing fast results.

Sales events are far more psychologically calculated than they first appear. (A) A crossed-out original price, for instance, makes the discounted price seem like an exceptional deal, regardless of whether it truly is one. (B) Retailers rely on specific visual and verbal cues to make shoppers feel they are getting exceptional value. (C) Combined with phrases suggesting limited availability, these cues push customers toward faster, less deliberate purchasing decisions.
