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. During non-REM sleep, especially its deepest stage, the brain waves slow down dramatically, the body temperature drops, and tissue repair and growth hormone release reach their peak. This is the period ①most closely associated with physical restoration. REM sleep, by contrast, brings rapid eye movements, near-total muscle paralysis, and brain activity that closely ②resemble wakefulness. Most vivid dreaming occurs during this stage, and researchers believe it ③plays a central role in consolidating memories and processing emotional experiences. A healthy night typically cycles through both stages four or five times, with non-REM ④dominating the early hours and REM periods lengthening toward morning. Disrupting either stage, through frequent awakenings or alcohol use, can leave a person ⑤feeling unrested even after a full night in bed.

Last summer, I ①worked part-time at a small coffee shop near my house. At first, I only wanted to earn some spending money, but the job ②taught me far more than that. I learned how to stay calm during busy hours when orders ③piled up quickly. One day, a customer complained loudly about a mistake in her order. Instead of ④argue, I apologized and quickly made a new drink for her. She left with a smile, and my manager praised my patience ⑤afterward.

Remote work has moved from a rare privilege to a common practice for millions of employees worldwide. Many companies that once required workers ①to commute daily now allow them to complete tasks from home. Supporters argue that remote work increases productivity, since employees avoid long commutes and ②distracting office environments. It also allows companies to hire talented people regardless of where they live, ③widening the pool of candidates. Critics, however, worry that remote work weakens teamwork and ④make it harder for new employees to learn from experienced colleagues. Without regular face-to-face interaction, some workers feel isolated and ⑤struggle to build strong professional relationships.

Blockchain technology was originally promoted as a way ①to remove the need for trusted middlemen, allowing strangers to exchange value directly and verify transactions through a shared, tamper-resistant ledger rather than through a bank or government agency. In theory, this design ②distributes power away from any single institution and toward the network as a whole. In practice, however, a small number of large players have come to dominate many blockchain networks, ③controlled enough computing power or currency to influence outcomes that were supposed to be decided collectively. Critics note a further irony: when something goes wrong, there is often no institution left ④to appeal to, since the entire system was designed precisely to eliminate that kind of central authority. Whether decentralization can survive this concentration of power ⑤remains one of the technology's most unresolved questions.

As companies collect enormous amounts of personal data to improve their products and target advertisements, serious ethical questions ①have emerged about how that information should be handled. Employees who work with big data now face responsibilities ②that previous generations rarely encountered, since a single careless decision can expose millions of people's private information. Some argue that strict regulations should govern data collection, even if such rules ③slow innovation and increase costs for businesses. Others insist that self-regulation within companies, guided by clear ethical training, can ④protects consumers just as effectively without stifling progress. Universities have begun adding data ethics courses to computer science programs, ⑤recognizing that future employees will need to balance innovation with responsibility.

A striking proportion of individual investors believe their own stock-picking ability to be above average, a statistical ①impossibility given that only half of any population can genuinely outperform the rest, yet a pattern that persists with remarkable consistency across surveys. This tendency, known as overconfidence bias, leads investors to trade more ②frequently than a more cautious assessment of their own skill would justify. Extensive research comparing the trading records of numerous individual accounts has ③demonstrated that investors who trade most frequently tend to earn substantially ④higher returns than those who trade rarely, largely because transaction costs accumulate and because frequent trading often reflects overconfident reactions to short-term noise rather than genuine insight. Overconfidence also manifests in the tendency to underestimate the range of possible outcomes, causing investors to concentrate their holdings in a small number of assets they feel certain about rather than diversifying across a broader portfolio. Paradoxically, then, the very confidence that motivates investors to act decisively often ⑤undermines the outcomes they are trying to achieve.

The Riverside Summer Festival will take place from August 1st to August 3rd at Riverside Park. This annual event offers a variety of programs for visitors of all ages, and admission is ①free for everyone. During the day, local farmers will sell fresh fruits and handmade crafts at outdoor booths, and in the evening, live music performances will ②entertain the crowd. Visitors are encouraged to bring their own water bottles, since most areas of the park ③allow vehicles freely. Parking near the park is ④limited, so using public transportation is strongly recommended. Organizers hope this festival will bring the community ⑤together for a memorable summer weekend.

As governments and companies work to address climate change, a new category of employment known as green jobs has expanded rapidly. Critics point out that transitioning workers from fossil fuel industries to green jobs is not always simple, since the required skills can differ significantly. Governments are therefore introducing training programs designed to help such workers shift smoothly into renewable energy careers. As climate goals become more urgent worldwide, ___________.

After learning that my constant headaches were caused by air-conditioning sickness, I decided to change a few habits. (A) Next, I made sure to drink warm water instead of only cold drinks throughout the day. (B) First, I began carrying a light jacket to wear whenever a room felt too cold. (C) Finally, I started stretching and walking around every hour instead of sitting still all day.

Meanwhile, the underlying technology continues to advance regardless of whether the diplomacy meant to govern it keeps pace. Military researchers have developed weapons systems capable of identifying and engaging targets without a human pressing the final button, a prospect that has alarmed arms control experts for over a decade. ( ① ) Advocates within defense agencies argue that autonomous systems can react faster than any human operator and may even reduce casualties. ( ② ) Human rights organizations counter that removing a person from the final decision strips away moral responsibility at the exact moment it matters most. ( ③ ) Diplomatic negotiations toward an international treaty have repeatedly stalled, partly because military powers disagree on how to define autonomy precisely enough to regulate it. ( ④ ) This disagreement has left the treaty process without a clear path forward. ( ⑤ )
