Feed an AI music program a mood, a tempo, and a rough genre, and within seconds it can generate a complete instrumental track, ①ready to be dropped under a video or used as background music for a small business. The software has studied thousands of existing songs, ②learning which chord progressions and rhythms tend to sound pleasant together, and it recombines these patterns into something new rather than ③copying any single source directly. For independent creators who cannot afford a composer or expensive licensing fees, this has been a genuine breakthrough. Professional musicians, however, remain divided. Some welcome the tool as a quick way to sketch ideas before ④refine them by hand, while 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 ⑤relied on to build a career.

Psychologists have long studied a mechanism called the variable reward schedule, in which rewards ①arrive unpredictably rather than after every single action. Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. When someone posts a photo, they cannot predict exactly when likes will appear, nor ②how many they will eventually receive. This uncertainty triggers a small burst of dopamine each time the phone ③is checked, regardless of whether the result is disappointing or thrilling. Consequently, users often refresh their feeds compulsively, ④hoping the next check will finally bring a satisfying reward. What makes this troubling is that technology companies deliberately designed notification systems using insights borrowed from gambling research, rather than ⑤stumble upon them by accident.

Imagine two factories making the same product: one in a country with ①strict carbon rules, and one in a country with almost none. The factory facing stricter rules often spends more, which can make its goods ②pricier 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 ③protects domestic industries and pushes foreign manufacturers toward cleaner methods. However, critics claim it unfairly ④benefits 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 ⑤little to global emissions. Still, if wealthier nations pair the policy with technical support, it could become a genuinely fair tool for cutting emissions worldwide.

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 that assemble products with remarkable precision, and warehouses use automated systems to sort and deliver packages within a few hours. This shift does not simply eliminate jobs; it also creates roles that never existed before. Technicians who maintain robotic equipment are now in high demand, and engineers who design efficient automated systems are highly valued. Companies that invested early in automation often report ___________, since machines handle repetitive tasks while employees focus on creative problem-solving. This transition, however, also raises concerns about workers whose skills quickly become outdated. Policymakers argue that retraining programs are essential to help displaced workers move into emerging fields.

Many companies now advertise themselves as environmentally responsible, yet a growing number of these claims turn out to be misleading. This practice, known as greenwashing, _______________. A company might launch a recycled-packaging line while continuing 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 lack the tools to verify corporate claims. In contrast, truly sustainable businesses publish detailed, independently verified data about their emissions and supply chains, allowing outsiders to check their progress. Therefore, shoppers should look beyond vague labels like green or natural and instead search for recognized certifications, transparent reports, and measurable targets. Without such scrutiny, greenwashing will keep flourishing, undermining public trust and slowing the broader shift toward an economy that truly protects the planet.

Implementation intentions have become one of the most widely studied tools in behavioral psychology for helping people reach their goals. (A) Unlike a vague goal such as "I will exercise more," an implementation intention specifies both the situation that triggers the behavior and the exact action that follows. (B) Because the decision has already been made in advance, people no longer need to rely on willpower at the critical moment when the temptation to skip arises. (C) For example, a person might decide, "If it is seven in the morning, then I will put on my running shoes immediately," rather than simply hoping to find time to exercise.

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.

주어진 문장: Over time, these short breaks stopped feeling like sacrifices and started feeling like small rewards. For most of last year, Junho refreshed his social media feed constantly, terrified of missing a party, a trending meme, or gossip among his friends. ( ① ) This restless anxiety, often called FOMO, or the fear of missing out, left him exhausted and strangely unsatisfied even after hours of scrolling. ( ② ) One weekend, his phone battery died during a hiking trip, and, to his surprise, he actually enjoyed the quiet afternoon without notifications interrupting his thoughts. ( ③ ) Curious about this unexpected calm, Junho began deleting social apps for a few hours each day, gradually extending the breaks as weeks passed. ( ④ ) Instead of dreading what he might be missing, he started noticing small pleasures, such as finishing a book or having an uninterrupted conversation with his family. ( ⑤ ) This shift in attitude reflects what psychologists now call JOMO, the joy of missing out, a mindset that treats disconnection as freedom rather than loss.

주어진 문장: Every choice, from filters to captions, is carefully calculated to create a favorable impression on viewers. Sociologist Erving Goffman argued that people constantly perform for others, much like actors managing their image on a stage, a concept known as impression management. ( ① ) This idea applies vividly to social media, where users select flattering photos and delete posts that might damage their reputation. ( ② ) Such careful curation allows people to present an idealized version of themselves that emphasizes achievements while hiding struggles or ordinary moments. ( ③ ) However, when this performance becomes constant, a troubling gap can form between one's authentic self and the polished character displayed online. ( ④ ) Maintaining that gap requires considerable emotional energy, and studies suggest it often leads to anxiety and exhaustion. ( ⑤ ) Furthermore, comparing one's own carefully staged life to others' equally staged posts can distort what people believe is normal. Therefore, individuals should recognize that some self-presentation online is inevitable, but they must also protect space where imperfection is allowed to remain visible.

주어진 문장: This lack of accountability makes silence feel like a reasonable, even harmless, choice. Social psychologists describe a phenomenon called the bystander effect, in which individuals become less likely to help a victim as the number of witnesses increases. ( ① ) Each observer assumes someone else will step in, and this diffusion of responsibility leaves no one willing to act. ( ② ) Cyberbullying magnifies this problem, since a single humiliating post can be witnessed by thousands of people scattered across the internet rather than a few standing nearby. ( ③ ) Anonymity intensifies the effect further, allowing silent observers to scroll past cruel comments without feeling accountable for their inaction. ( ④ ) Some bystanders even worry that intervening publicly might make them the bully's next target, so they choose to remain silent instead. ( ⑤ ) However, silence signals approval to both the bully and the audience watching the exchange unfold. Experts insist that even a single supportive comment can disrupt this harmful pattern. Therefore, witnesses online must resist staying passive and instead speak up.
