Coaches have traditionally focused athlete preparation on training volume and nutrition, but a growing body of research ① suggests that sleep deserves equal attention. During deep sleep, the body releases growth hormone, a substance essential for ② repairing muscle tissue damaged during intense training, while the brain consolidates motor skills practiced earlier that day into more stable, efficient patterns. Athletes who sleep fewer than seven hours a night have been shown ③ suffering more injuries, slower reaction times, and reduced accuracy compared to well-rested peers performing the identical drills. Frequent travel across time zones compounds this challenge considerably, since jet lag can ④ disrupt an athlete's natural sleep-wake cycle for several days after a long flight. In response, many professional teams now employ sleep specialists ⑤ who design travel schedules, control bedroom lighting and temperature, and even adjust competition start times when possible.

Retailers frequently rely on sales events to boost short-term revenue, but the psychology behind these promotions is more complex than simple discounting. When a price is crossed out and replaced with a lower number, consumers instinctively ①perceive the new price as a bargain. This technique, ②known as anchoring, shapes how shoppers judge value by comparing prices rather than evaluating a product on its own merits. Limited-time sales further intensify this effect, since a ticking clock ③encourage rushed decisions that leave little room for careful comparison. Retailers also use phrases such as "while supplies last" to suggest scarcity, even when inventory ④remains plentiful. Over time, frequent sales can actually train customers ⑤to wait for discounts rather than buy at full price.

Insomnia is rarely caused by a single factor; it usually emerges from an interaction between psychological stress and physiological arousal that ① keeps the body from settling into sleep. A common trigger is what researchers call cognitive hyperarousal, in which the mind continues ② to racing with worries about work, relationships, or even the inability to sleep itself, creating a frustrating cycle where anxiety about insomnia becomes a cause of insomnia. At the same time, the body's stress response system can become chronically activated, ③ releasing hormones such as cortisol that keep heart rate and body temperature elevated at night, both of which interfere with the natural drop in arousal needed to fall asleep. Poor sleep habits, including irregular bedtimes and excessive screen use before bed, can further ④ weaken the body's internal signals for sleep onset. Because these psychological and physiological factors reinforce one another, effective treatment for chronic insomnia addresses both the racing mind and the underlying pattern of physical tension, rather than ⑤ relying on medication alone.

Jiho had always assumed he would join a large corporation after graduation, just as his parents expected. During his final year of university, however, he joined a small student team building an app that connected local farmers directly with restaurants. What started as a class project gradually turned into something more ①serious, as several restaurants began placing regular orders through their prototype. Jiho and his teammates decided to ②abandon their idea and instead spend a year developing it further, despite warnings from relatives who considered the plan too risky. They worked from a cramped apartment, surviving on ③limited savings while learning skills ranging from coding to negotiating with suppliers. After nearly failing twice, the team secured a small investment that allowed them to hire their first ④employee. Looking back, Jiho believes that the uncertainty of startup life taught him far more about problem-solving than any traditional job could have ⑤offered.

Travelers who cross several time zones in a single flight often arrive feeling exhausted, foggy, and strangely out of sync with the local clock, a condition widely known as jet lag. The discomfort arises because the body's internal clock continues to run on the schedule of the departure city even after landing. Realigning this internal clock to a new time zone is not instantaneous; researchers estimate that the body typically needs about one day to adjust for every time zone crossed. Flying eastward tends to produce more severe symptoms than flying westward, because _______________. Exposure to natural light at the right moments after arrival can help speed up the adjustment, since light is the strongest external cue the internal clock uses to reset itself.

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.

Many self-help books emphasize the cue-routine-reward loop as a tool for building better habits. (A) For example, athletes who want to build a stretching habit often rely on a specific cue, such as arriving at the gym, to trigger the same short routine every time. (B) Over time, this consistent pairing strengthens the neural pathway connecting the cue to the routine, making the behavior feel almost automatic. (C) According to this model, every habit consists of three connected parts: a cue that triggers behavior, a routine that follows, and a reward that reinforces it.

Generation Z is reshaping consumer culture in ways that surprise many traditional marketers. (A) As a result, brands that rely solely on flashy advertising campaigns often struggle to win their loyalty. (B) They tend to research thoroughly before buying and expect companies to demonstrate genuine values, not just attractive slogans. (C) Instead, this generation responds more strongly to transparency and honest communication from the brands they support.

Not all obstacles to renewable energy are technical or financial; some are psychological. (A) In contrast, switching demands research, upfront cost, and trust in unfamiliar technology, all of which can seem risky compared with doing nothing. For example, a neighborhood association might repeatedly postpone a vote on shared solar panels, not because the plan is flawed, but because members are reluctant to leave their routine. Therefore, boosting renewable adoption may depend less on proving its advantages and more on designing programs that make the first step feel easy. (B) Behavioral economists use the term status quo bias to describe a tendency to prefer the present situation over a new alternative, even when the alternative would bring greater benefits. (C) This bias helps explain why many households hesitate to switch to renewable energy, such as installing solar panels on their roofs. Although solar panels can lower electricity bills over time, homeowners often stick with their current power source because it feels safe and requires no immediate effort.

주어진 문장: The financial and reputational damage caused by a single attack can be enormous. As more businesses move their operations online, cyberattacks have become one of the most serious threats facing modern companies. ( ① ) Hackers now target everything from small retail websites to massive financial institutions, stealing sensitive data or demanding ransom payments. ( ② ) In response, demand for cybersecurity professionals has surged across nearly every industry. ( ③ ) These specialists design systems that detect suspicious activity, patch vulnerabilities before criminals can exploit them, and train employees to recognize phishing attempts. ( ④ ) Universities have responded by creating specialized degree programs, while many companies now offer scholarships to attract students into this growing field. ( ⑤ ) Despite this expansion, experts estimate that millions of cybersecurity positions worldwide remain unfilled.
