Even a modest level of dehydration, as little as two percent of body weight ① lost through sweat, can measurably reduce an athlete's endurance and cognitive sharpness during competition. As fluid levels drop, blood volume decreases, ② forcing the heart to work harder to deliver the same amount of oxygen to working muscles, which accelerates fatigue. Dehydration also impairs the body's ability ③ to regulate its own temperature, since sweating is the primary mechanism for releasing excess heat during intense exercise. Athletes competing in hot, humid conditions face a particularly difficult balance, because sweating heavily to stay cool simultaneously ④ depletes the very fluids needed to sustain performance. For this reason, sports scientists generally recommend a hydration strategy ⑤ tailoring to an individual athlete's sweat rate and the specific conditions of the event.

Many companies today advertise their products as environmentally friendly, yet not all of these claims are accurate. This practice, ①knowing as greenwashing, involves exaggerating or fabricating a product's positive impact on the environment. Consumers, ②who are increasingly concerned about climate change, often trust such claims without questioning them closely. As a result, they may pay higher prices for products ③that are no more sustainable than ordinary alternatives. Genuine environmental efforts, which usually ④require significant investment and long-term planning, are far more costly than simply changing a label. Therefore, governments should establish clear standards ⑤that require companies to prove their environmental claims with verifiable data.

Marketers have long recognized that perceived scarcity, the sense that a product or opportunity ①are available only in limited quantity or for a limited time, can dramatically increase its desirability, even when the item's intrinsic qualities remain entirely unchanged. This phenomenon, known as the scarcity effect, operates on a simple psychological principle: when something appears difficult to obtain, people tend ②to infer that it must be valuable, since truly worthless items rarely generate genuine competition for possession. A retailer who labels a product as "limited edition" or displays a countdown timer beside a discounted offer exploits this inference, ③prompting customers to make hurried purchase decisions they might otherwise postpone or reconsider. Experimental studies confirm that identical products ④are rated as more desirable and often command higher prices when framed as scarce than when the same products are presented as widely and continuously available. The effect intensifies further when scarcity is attributed to high demand rather than to limited supply alone, since competition from other buyers ⑤introduces an additional layer of urgency absent from mere supply constraints.

Last January, Minji wrote the same resolution she always wrote: study English for an hour every day. By February, she had already ①quit, just as in previous years. Frustrated, she asked her teacher why her willpower always failed, and learned about a concept ②called implementation intentions. Instead of vaguely intending to study more, Minji made a precise plan: if she finished dinner, then she would study for thirty minutes. She also ③prepared a backup plan: if she felt too tired, then she would study for just ten minutes instead of skipping entirely. Because these plans removed the need to decide anything in the moment, starting became ④far more easily for Minji. By December, she had studied for eleven straight months, ⑤proving that clear if-then plans beat vague intentions.

A growing number of people are practicing what is now called digital detox, the deliberate decision to stop using smartphones for a set period. Rather than checking notifications every few minutes, participants unplug for a weekend, a week, or sometimes even longer. Numerous studies suggest that this temporary withdrawal produces ①real benefits for both the mind and the body. First, attention spans fragmented by constant notifications gradually ②recover, allowing people to concentrate on single tasks for longer stretches. Second, avoiding screens before bedtime ③worsens sleep quality, since blue light emitted by devices is known to disrupt natural sleep cycles. Third, people freed from their phones often rediscover the pleasure of face-to-face conversations that had been replaced by texting. Critics argue that complete disconnection is impractical in a hyperconnected society, yet even brief, regular breaks appear to ④restore balance. Therefore, scheduling periodic digital detox sessions deserves ⑤serious consideration.

Psychologist Roy Baumeister proposed a concept called ego depletion theory, which suggests that ___________. According to this theory, every act of self-control, from resisting a snack to concentrating on difficult homework, draws from the same limited mental resource. As this resource becomes depleted throughout the day, later decisions require more effort and are more likely to fail. For instance, someone who exercises discipline avoiding distractions all morning may struggle to resist checking a phone by evening. Likewise, dieters report that self-control weakens sharply at night, after hours of resisting food. Some researchers argue that short breaks, adequate sleep, and blood sugar levels can help restore this depleted resource. Although later studies have questioned how strong this effect is, the theory still offers a useful framework for understanding why willpower seems to fade throughout a long day.

Goal-setting theory has influenced not only classrooms but also workplaces around the world. (A) Many companies now train managers to set specific quarterly targets rather than simply asking employees to 'do their best.' (B) As a result, employees often report clearer priorities and a stronger sense of accomplishment. (C) These targets typically include measurable numbers, such as sales figures or project deadlines.

As a result, your body struggles to adapt, and this can weaken your immune system over time. Air conditioners make summer days more comfortable, but a larger gap between indoor and outdoor temperatures forces your body to face sudden changes again and again. ( ① ) Many people still set the temperature far below the outdoor temperature to cool down quickly, without realizing the risk. ( ② ) However, doctors recommend keeping the difference between indoor and outdoor temperatures within five or six degrees. ( ③ ) This often leads to symptoms such as headaches, fatigue, and a stuffy nose. ( ④ ) To avoid these problems, set a moderate temperature and open a window for a few minutes every hour. ( ⑤ ) Following these tips will help you stay both cool and healthy this summer.

주어진 문장: In other words, those who did the least to cause the problem often end up paying the highest price for it. When people discuss climate change, they often focus only on rising temperatures or melting ice, treating it as a purely scientific issue. ( ① ) However, the concept of climate justice reminds us that the causes and consequences of climate change are distributed unevenly across the globe. ( ② ) 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. ( ③ ) This gap between responsibility and suffering raises a serious ethical question that science alone cannot answer. ( ④ ) 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. ( ⑤ ) Therefore, tackling climate change requires more than new technology; it demands fair policies supporting the very communities least responsible for causing the crisis.

Consequently, even seasoned professionals who believe themselves immune to such influence often fail to notice how much their final judgment has shifted. The anchoring effect can be surprisingly resistant to conscious correction. ( ① ) Even when individuals are explicitly warned in advance that a number they are about to see is randomly generated and therefore meaningless, their subsequent estimates still drift toward that arbitrary figure. ( ② ) This occurs because the mind uses the initial number as a starting point and then adjusts insufficiently away from it, a process that leaves the final judgment biased toward the anchor. ( ③ ) Experimental studies have repeatedly demonstrated this effect across a wide range of tasks, from estimating historical dates to appraising real estate. ( ④ ) The bias persists not because people lack expertise, but because the adjustment process itself is inherently incomplete. ( ⑤ ) Awareness of the anchoring effect, therefore, does not guarantee immunity from it, which is precisely what makes the bias so difficult to counteract in practice.
