A short nap taken in the early afternoon, often called a power nap, can noticeably sharpen attention and mood without ①leaving a person groggy afterward. The key lies in timing: naps limited to roughly twenty minutes allow the brain ②to pass through the lightest stages of sleep while avoiding the deeper stages associated with slow-wave activity. If a nap extends much beyond that window, the sleeper risks ③waking during deep sleep, which produces a foggy, disoriented feeling known as sleep inertia that can persist for thirty minutes or more. Laboratory studies ④comparing napping and non-napping groups have repeatedly shown that a brief nap improves reaction time and short-term memory almost as effectively as a full night of extra rest. Interestingly, the benefit appears strongest when the nap occurs several hours after waking, since this is when the body's natural dip in alertness makes rest most ⑤effectively.

Artificial intelligence has begun to play a surprising role in creative industries ①once thought to be uniquely human. Programs can now compose music, generate paintings, and ②draft short stories within seconds. Some artists welcome this technology, ③used 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 ④that comes from genuine human experience. Therefore, artists who learn to work alongside AI, rather than compete against it, may find themselves ⑤with a distinct advantage.

The gig economy, in which people take on short-term or freelance jobs, ①has grown rapidly over the past decade. Digital platforms now connect customers directly with drivers, designers, and writers, ②allowing workers to choose when and how much they work. Businesses, meanwhile, can hire help only when they ③actually need it. For many young people entering the job market, gig work provides valuable flexibility ④that traditional employment rarely allows. However, gig workers often lack benefits such as health insurance, which full-time employees typical ⑤receive.

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.

Long before a user finishes typing a sentence, the keyboard on most smartphones has already begun guessing what word comes next. This feature relies on a language model trained to notice which words commonly follow one another, so it can offer a shortlist of likely candidates above the keyboard, ①saving users countless keystrokes over the course of a day. The system also adapts to each individual, gradually learning a person's favorite phrases, slang, and even the names of friends that no generic dictionary would ②recognize. This constant personalization, however, creates a subtle side effect that few users notice. Because the keyboard ③nudges people toward its own suggestions, some linguists worry that autocomplete may be quietly ④widening everyday vocabulary, encouraging writers to accept a convenient suggestion rather than searching for the more precise or original word they might otherwise have ⑤chosen.

After a viewer finishes an episode, a streaming service rarely leaves the choice of what to watch next entirely up to chance. Instead, a recommendation algorithm ①compares that viewer's habits with patterns drawn from millions of other users who watched similar content, then ranks thousands of titles in order of predicted interest. This approach keeps viewers ②disengaged far longer than a simple list of new releases ever could, which is precisely why streaming companies invest so heavily in refining it. The system is not without drawbacks, however. Because the algorithm favors titles similar to what a viewer already enjoys, it can quietly ③narrow someone's exposure to unfamiliar genres, directors, or cultures, creating a comfortable but repetitive bubble. Some platforms have begun inserting occasional wildcard suggestions, deliberately unrelated to past viewing habits, in an attempt to ④counteract this narrowing effect and keep recommendations from becoming too ⑤predictable.

When people discuss climate change, they often focus only on rising temperatures or melting ice, treating it as a purely scientific issue. However, the concept of climate justice reminds us that _______________. Wealthy, industrialized nations have historically released the largest share of greenhouse gases while building their economies, yet developing nations, which contributed comparatively little, frequently suffer the most severe droughts and floods. This gap between responsibility and suffering raises a serious ethical question that science alone cannot answer. For example, a farming community in a low-income country may lose its entire harvest to an unusual flood, even though its members have never owned a car or flown on a plane. Therefore, tackling climate change requires more than new technology; it demands fair policies supporting the very communities least responsible for causing the crisis.

When a customer opens a company's website at midnight with a billing question, an actual employee is unlikely to be available, which is exactly the gap that customer service chatbots were built to fill. These programs can instantly answer common questions, track packages, and process simple refunds without making anyone wait on hold. Yet the technology has clear boundaries. When a customer's problem is unusual, emotionally charged, or simply does not fit the chatbot's script, _______________. Many companies have responded by designing chatbots to recognize their own limits, automatically transferring a frustrated customer to a human agent.

Smart speakers have quietly become a fixture in many households, responding to spoken requests for weather updates, music, or kitchen timers. Because these assistants improve by learning from millions of interactions, they gradually become better at recognizing regional accents and casual phrasing that once confused them. Still, _______________. Engineers continue to refine these systems, but many admit that truly natural conversation remains one of the hardest goals in the entire field of artificial intelligence.

Some changes in habit begin not with a big decision but with a quiet moment that lingers in the mind. (A) That changed when her class was assigned a documentary about plastic waste drifting through the ocean, footage she initially expected to find boring. Instead, watching seabirds mistake plastic fragments for food left her strangely unsettled, and she found herself thinking about the assignment long after class ended. (B) The next morning, almost without deciding to, she slipped her old tumbler into her backpack instead of buying a disposable cup on the way to school. It felt like a small, meaningless gesture at first. However, as weeks passed, she realized that consistently choosing the tumbler, declining a plastic straw, and reusing a shopping bag were quietly adding up. Small choices, she discovered, become meaningful once repeated. (C) Until last spring, Minji rarely thought twice about tossing a paper cup into the trash after finishing her coffee. Environmental issues seemed distant, something scientists and politicians should handle rather than an ordinary student like her.
