Wearable devices ① that track sleep have become enormously popular, promising a detailed breakdown of light, deep, and REM sleep each night. These gadgets typically rely on movement sensors and heart rate monitors ② to estimate sleep stages, since directly measuring brain activity would require equipment found only in a sleep laboratory. Independent studies ③ compares wearable data with polysomnography, the gold-standard method used in clinical sleep labs, have found that consumer devices are reasonably accurate at distinguishing sleep from wakefulness but considerably less reliable at identifying specific sleep stages. Some trackers overestimate deep sleep, while others ④ underestimate the amount of time spent in REM sleep, and the margin of error can vary widely between brands. Despite these limitations, many users have come ⑤ to treat the nightly score generated by their device as an objective medical verdict, sometimes experiencing anxiety when the number falls below what they expect, a phenomenon researchers have begun calling orthosomnia.

Heatstroke happens when the body's temperature ①rises too high and cannot cool itself down. To prevent heatstroke, you should drink plenty of water throughout the day, ②even if you do not feel thirsty. If you notice symptoms such as dizziness or a very high body temperature, ③move to a shaded place immediately. Children, ④who sweat less than adults, are especially at risk of heatstroke. It is also wise ⑤avoiding outdoor activities between noon and five o'clock, when the sun is strongest.

Last spring, I ①joined a one-day job experience program at a local hospital. I had always been curious about becoming a nurse, so I signed up without hesitation. A kind nurse ②named Ms. Park showed me around the ward, ③explaining how nurses check patients' conditions. At first, I was nervous about talking to real patients. However, after ④help an elderly patient find her room, I felt proud and relaxed. I realized that teamwork ⑤matters as much as medical knowledge.

When choosing a future career, students often face a common question: should I follow what I love, or what I ①being good at? Passion can provide strong motivation, ②pushing a person to practice for hours without feeling tired. However, loving an activity does not always mean a person will become skilled at it professionally. Natural talent can lead to quick success, but without genuine interest, that success may eventually feel ③empty or exhausting. Career experts suggest ④looking for an overlap between the two. Finding this balance takes time and self-reflection, but it often leads to a more ⑤satisfying and sustainable career.

Writing a personal statement can feel overwhelming, but a few simple strategies ①make the process easier. First, avoid ②to list your achievements simply; instead, explain what each experience taught you and how it shaped your goals. Second, use specific examples rather than vague statements, since details make your story more ③convincing and memorable. Third, keep your tone honest and natural, because reviewers can easily notice writing ④that sounds forced or overly formal. Finally, always proofread carefully, since small errors can ⑤distract readers from an otherwise strong statement.

A rational approach to decision-making dictates that only future costs and benefits should influence a choice, since resources already spent cannot be ①recovered regardless of what is decided next. In practice, however, people routinely allow such irrecoverable expenditures, known as sunk costs, to shape their subsequent decisions, a pattern referred to as the sunk cost fallacy. A moviegoer who finds a film thoroughly ②disappointing after the first thirty minutes will often remain in the theater until the credits roll, reasoning that leaving early would somehow waste the money already spent on the ticket. Organizations exhibit the same fallacy on a larger scale: a company that has invested heavily in a failing project frequently ③abandons funding it, arguing that stopping the project now would render the prior investment meaningless. Yet continuing to invest in a venture destined to fail merely adds new losses to old ones, ④compounding the very waste the decision-makers hoped to avoid. Economists therefore urge decision-makers to evaluate each choice based solely on its prospective outcomes, treating past expenditures as ⑤irrelevant to the decision at hand.

Among strategies for improving ①concentration, the Pomodoro Technique remains one of the most widely recommended methods for students and workers. This technique involves working with full attention for twenty-five minutes, then taking a short five-minute break before starting the next session. After completing four of these cycles, a longer break of fifteen to thirty minutes is usually taken to allow mental ②recovery. The method assumes that sustained focus becomes harder to maintain as time passes, so frequent short breaks prevent mental ③fatigue from building up. Students preparing for exams report finishing reading assignments faster when they follow this structured rhythm instead of studying without interruption. Office workers find that dividing large projects into short, timed intervals makes overwhelming tasks feel more ④manageable. Because each interval has a clear start and end, procrastination becomes ⑤more tempting, since beginning a single twenty-five-minute session requires less commitment than beginning an entire project.

The term green premium _______________. For example, an electric vehicle or solar-powered appliance often carries a higher price tag than its gasoline-powered or coal-based counterpart, even though it produces fewer emissions over time. This price gap frequently discourages shoppers who support sustainability in principle but cannot justify the additional expense within a limited household budget. In contrast, wealthier consumers can absorb the premium more easily, which creates unequal participation in green markets. To narrow this gap, governments have introduced subsidies and tax credits that lower upfront costs, while companies invest in research to make clean technologies cheaper to manufacture. As production scales up and innovation continues, many economists expect the green premium to shrink steadily, eventually making sustainable choices the more affordable option for most consumers.

The gap between popular belief and scientific evidence about habit formation has surprised many researchers. (A) This finding suggests that people who quit a new habit after only three weeks may simply be giving up too early, not failing at the habit itself. (B) Their results showed that habits took an average of sixty-six days to become automatic, far longer than the widely repeated twenty-one-day figure. (C) To test how long habit formation truly takes, scientists asked volunteers to track a new daily behavior for several months.

Debates about remote work often focus on how it affects both individual employees and entire organizations. (A) For instance, several surveys show that remote employees report higher job satisfaction and fewer sick days than office-based workers. (B) On the other hand, managers point out that spontaneous conversations, which often spark new ideas, rarely happen when everyone works separately. (C) Some studies highlight clear benefits for workers, showing that flexible schedules reduce stress and improve overall well-being.
