Many people struggling to fall asleep in noisy environments turn to white noise machines, devices that emit a ①chaotic, uniform sound covering a broad range of frequencies. The appeal lies in a phenomenon called auditory masking, in which a constant background sound makes sudden noises, such as a slamming door, ②less noticeable to the sleeping brain. Without this masking effect, an abrupt change in sound is far more likely to trigger a brief awakening, even if the sleeper does not ③consciously remember it the next morning. Studies comparing sleep in quiet rooms with sleep alongside white noise have found that participants using white noise experienced fewer of these brief awakenings and reported feeling more ④rested. However, researchers caution that the benefit depends heavily on volume and consistency, since noise that is too loud or that varies unpredictably can itself become a source of ⑤disruption rather than a remedy.

Psychologist Leon Festinger introduced social comparison theory, which explains that people ①evaluate their own abilities and opinions by comparing themselves with others. According to this theory, individuals engage in upward comparison when they measure themselves against someone who appears more ②successful, attractive, or accomplished. For instance, a teenager browsing vacation pictures posted by classmates may begin to feel that her own ordinary life is somehow ③inadequate. Unlike comparing oneself with someone in a similar position, which can sometimes ④boost confidence, upward comparison frequently triggers envy, dissatisfaction, and lower self-esteem. Researchers have found that frequent upward comparison online is linked to ⑤lower depression and anxiety.

Sleep hygiene refers to a set of simple daily habits that help the body prepare for consistent, ①restorative rest. Experts commonly recommend going to bed and waking up at the same time every day, even on weekends, because an irregular schedule ②clarifies the body's internal clock and makes it harder to fall asleep on demand. They also advise reserving the bedroom for sleep alone, since using the bed to study, scroll through a phone, or watch videos teaches the brain to associate that space with ③wakeful activity rather than rest. Physical environment matters as well: a cool, dark, and quiet room tends to produce ④deeper sleep than one that is warm, bright, or noisy. None of these individual habits guarantees a good night's sleep on its own, but together they form a routine that gradually trains the body to expect and enter sleep more easily, much the way a ⑤consistent set of cues trains an athlete's body to perform at a certain time each day.

Building brand loyalty has traditionally been considered one of the most valuable goals in marketing, since loyal customers tend to spend more and recommend products to others. Companies invest significant resources in loyalty programs, offering points, discounts, and exclusive access to encourage repeat purchases. However, some critics argue that these programs manipulate consumers into staying with a brand out of habit rather than genuine satisfaction. Genuine loyalty, they contend, should be earned through consistent quality and honest treatment of customers, not through artificial incentives that merely delay a customer's departure. As markets become more competitive, relying solely on loyalty programs without addressing underlying product quality may ultimately backfire. Therefore, companies should treat loyalty ___________.

Secondhand trading platforms, once considered a niche market for used goods, have grown into a mainstream part of consumer culture. Rising prices for new products, combined with growing awareness of environmental waste, have encouraged many shoppers to consider used items before purchasing something brand new. These platforms allow individuals to sell clothing, electronics, and furniture directly to other consumers, cutting out traditional retail markups entirely. However, buying secondhand carries certain risks, since items cannot always be inspected closely before purchase, and some sellers misrepresent the condition of their products. To address this problem, many platforms now offer buyer protection programs and detailed rating systems for sellers. As trust in these systems continues to grow, ___________.

Sleep apnea is a disorder in which breathing repeatedly stops and restarts during sleep, often because the muscles at the back of the throat relax too much and block the airway. (A) Doctors therefore rely less on a patient's own account of the night and more on objective measurements, such as overnight oxygen levels and airflow patterns recorded in a sleep laboratory. (B) Each pause can last from a few seconds to over a minute, and it may occur dozens of times in a single night without the sleeper ever waking up fully. (C) Because these interruptions rarely produce a clear memory the next morning, many people remain unaware that anything is wrong, even as chronic fatigue, headaches, and irritability build up over months.

Every cell in the human body follows an internal timer known as the circadian rhythm, a roughly twenty-four-hour cycle that governs when we feel alert and when we feel drowsy. (A) This clock is regulated primarily by a tiny cluster of neurons in the brain that responds to light entering through the eyes, signaling the body to suppress sleep hormones each morning. (B) As evening approaches and light fades, however, the same mechanism triggers the release of melatonin, a hormone that promotes drowsiness. (C) Because this rhythm evolved around the natural cycle of day and night, modern habits such as artificial light exposure or night shifts can push it out of sync, which has been linked to digestive problems and reduced concentration.

Elite athletes rarely walk up to a free throw line or a golf ball without first performing a highly specific sequence of movements, a habit sports psychologists call a pre-performance routine. (A) Researchers have found that athletes who follow a consistent routine tend to show more stable performance under pressure than those who approach each attempt differently. (B) Far from being mere superstition, this consistent sequence serves a genuine cognitive purpose, narrowing an athlete's focus away from distracting thoughts and toward the specific technical cues needed to execute the skill correctly. (C) For this reason, coaches now actively teach young athletes to develop and rehearse individualized routines rather than treating them as personal quirks.

Daniel's career reflects how much the space industry has changed since he was a child. (A) As a result, he came to believe that opportunities in space exploration were no longer limited to a small number of government scientists. (B) By the time he entered university, private companies had begun launching satellites and building reusable rockets. (C) This shift eventually led him to join a startup developing lunar landing equipment, a job that barely existed when he first imagined his future.

주어진 문장: Because the timer makes each interval visible and concrete, students often feel a stronger sense of urgency during each session. Among strategies for improving concentration, the Pomodoro Technique remains one of the most widely recommended methods for students and workers. ( ① ) This technique involves working with full attention for twenty-five minutes, then taking a short five-minute break before starting the next session. ( ② ) After completing four of these cycles, a longer break of fifteen to thirty minutes is usually taken to allow mental recovery. ( ③ ) The method assumes that sustained focus becomes harder to maintain as time passes, so frequent short breaks prevent mental fatigue from building up. ( ④ ) 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 manageable. ( ⑤ ) Because each interval has a clear start and end, procrastination becomes less tempting, since beginning a single twenty-five-minute session requires less commitment than beginning an entire project.
