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.

Imagine two factories making the same product: one in a country with strict carbon rules, and one in a country with almost none. The factory facing stricter rules often spends more, which can make its goods 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 _______________. However, critics claim it unfairly burdens 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 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.

Sleep debt refers to the cumulative gap between the amount of sleep a person needs and the amount they actually get. Unlike a financial debt, however, this deficit cannot simply be repaid with a single long weekend of rest. When someone loses two hours of sleep every night for a week, the body does not treat the shortage as fourteen separate small losses; instead, it accumulates the deficit, and _______________. Researchers have found that even modest, chronic sleep restriction gradually impairs reaction time and decision-making, often without the affected person noticing the decline. This is because subjective feelings of tiredness tend to plateau after a few days, even as objective performance keeps deteriorating. Consequently, people frequently underestimate how much sleep debt they are carrying until a demanding task suddenly exposes the accumulated cost.

Minji looked forward to Jimin's livestreams every single evening without fail. (A) Eventually, at a crowded fan event, Jimin treated her exactly like any other stranger waiting in line. (B) Over time, she began to feel that the two of them shared a genuine, personal friendship. (C) That moment made Minji realize that the closeness she had felt existed only on her side.

Introducing cobots into a factory requires careful planning to ensure both safety and productivity. (A) Once installed, however, cobots must be closely monitored, since their sensors can occasionally malfunction in noisy or crowded environments. (B) Engineers must first program the robots to recognize the exact boundaries of each worker's movement space. (C) After this initial setup, cobots can be integrated gradually, starting with simple tasks before taking on more complex ones.

When people consistently sleep too little, the body's hormonal balance shifts in ways that can quietly encourage weight gain. (A) Two hormones in particular play opposing roles in regulating appetite: leptin signals fullness to the brain, while ghrelin stimulates the sensation of hunger. (B) At the same time, insufficient sleep interferes with how efficiently the body processes glucose, making cells less responsive to insulin and leaving more sugar circulating in the bloodstream than usual. Over months or years, this combination of increased appetite and reduced insulin sensitivity can contribute to steady weight gain and raise the risk of developing type 2 diabetes. (C) Studies show that sleep deprivation lowers leptin levels while raising ghrelin levels, so a tired body ends up feeling hungrier than it actually needs to be, even after a normal-sized meal.

주어진 문장: Without such outside checks, companies could easily present exaggerated or even false claims as genuine achievements. As consumers become more aware of global social and environmental issues, many now expect companies to take responsibility beyond simply selling products. ( ① ) 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. ( ② ) Companies that ignore these concerns risk public backlash, especially when unethical practices are exposed through investigative journalism or social media. ( ③ ) Some corporations have responded by publishing detailed sustainability reports, though critics question whether these documents reflect genuine change or merely serve as public relations tools. ( ④ ) Real accountability, according to many experts, requires independent verification rather than self-reported claims that cannot be easily checked. ( ⑤ ) Consumers, for their part, must also remain vigilant, since a company's marketing language does not always match its actual practices.

주어진 문장: This constant tracking allows algorithms to build a detailed profile of each user's interests over time. Internet activist Eli Pariser introduced the term filter bubble to describe a phenomenon created by online algorithms. Social media platforms and search engines constantly track which links users click and how long they linger on certain posts. ( ① ) Based on this data, algorithms predict what each individual is most likely to enjoy and quietly prioritize similar content in future results. ( ② ) As a result, two people who type the same search query can receive strikingly different results, each tailored to personal history. ( ③ ) This automatic filtering happens silently, without users ever deciding to limit what they see. ( ④ ) Consequently, many people gradually lose access to viewpoints that challenge their existing beliefs, even though they never intended to avoid them. ( ⑤ ) Pariser warned that this invisible curation could weaken democratic debate by narrowing public discussion. Therefore, some experts argue that platforms should reveal how content is filtered, letting users knowingly escape their own bubbles.

주어진 문장: This growing academic attention reflects how seriously the issue is now being taken. As companies collect enormous amounts of personal data to improve their products and target advertisements, serious ethical questions have emerged about how that information should be handled. ( ① ) Employees who work with big data now face responsibilities that previous generations rarely encountered, since a single careless decision can expose millions of people's private information. ( ② ) Some argue that strict regulations should govern data collection, even if such rules slow innovation and increase costs for businesses. ( ③ ) Others insist that self-regulation within companies, guided by clear ethical training, can protect consumers just as effectively without stifling progress. ( ④ ) Most experts agree that professionals handling sensitive data must be trained not only in technical skills but also in ethical decision-making. ( ⑤ ) Universities have begun adding data ethics courses to computer science programs, recognizing that future employees will need to balance innovation with responsibility.

Some schools have begun asking students to submit an early draft alongside the final version, specifically to preserve evidence of a student's own original voice. Highlighting an awkward sentence and instantly seeing three smoother alternatives has become a routine part of writing for many students, thanks to AI writing assistants built into word processors and browsers. ( ① ) These tools check grammar and spelling, of course, but the more advanced versions go further, suggesting clearer phrasing, flagging repetitive words, and even adjusting tone to sound more formal or more casual depending on the purpose. ( ② ) Teachers generally welcome the grammar and spelling support, since it frees up class time to focus on argument and structure rather than comma placement. ( ③ ) Concerns grow, however, around the tone and phrasing suggestions, which can gradually nudge every student's writing toward a similar, polished style. ( ④ ) This makes it harder to tell an individual voice from a suggestion generated by the same underlying model. ( ⑤ )
