Cities are frequently several degrees warmer than the surrounding countryside, a phenomenon ①known as the urban heat island effect, which intensifies in summer and threatens public health. This disparity arises largely because asphalt and concrete absorb solar radiation during the day and slowly release it as heat throughout the night, ②preventing urban areas from cooling down. To address this problem, urban planners have begun implementing mitigation strategies ③designed to lower surface and air temperatures. One widely used solution involves reflective "cool" roofing ④engineered to reflect more sunlight than dark rooftops absorb. Another strategy, green infrastructure, incorporates rooftop gardens and tree-lined streets that ⑤provides shade while releasing moisture.

Anthropologist Robin Dunbar ①proposed a concept now known as Dunbar's number, suggesting that human beings can only maintain about one hundred fifty stable social relationships at any given time. This limit, he argued, comes from the size of the human brain, ②which restricts how many meaningful connections a person can cognitively manage. In contrast, many social media users today have hundreds or even thousands of online friends and followers, a number far ③exceeding what Dunbar's research predicts. However, having numerous digital contacts does not necessarily mean that all of these relationships ④are close or emotionally supportive. Most users, when asked, admit that they interact regularly with only a small fraction of their total followers, while the rest remain ⑤largely unnoticing.

Classical economic models typically assume that people discount future rewards at a constant rate, ①valuing a reward received later somewhat less than an identical reward received now. Empirical observation, however, reveals a different pattern: people apply a much steeper discount to the immediate future than to the distant future, a phenomenon ②termed hyperbolic discounting. This inconsistency explains why an individual might sincerely resolve tonight to wake up early and exercise tomorrow, only to postpone the plan once tomorrow actually arrives and the immediate discomfort of getting out of bed ③become vivid and present. When the reward or cost in question lies safely in the future, its emotional weight remains muted, ④allowing rational long-term goals to dominate one's stated intentions. Once that same reward or cost draws near, however, its immediacy triggers a disproportionately strong emotional pull, frequently ⑤overriding the very plans made earlier with such apparent confidence.

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.

Before making a purchase, most online shoppers now read reviews written by previous customers rather than relying solely on advertisements. These reviews, posted by people who have no financial connection to the seller, often seem more ①trustworthy than promotional claims. Research shows that products with a large number of positive reviews sell significantly ②more than those with few or no reviews at all. However, fake reviews written by paid writers or even automated programs have become a serious problem, ③undermining consumer trust. Platforms that fail to detect these fraudulent posts risk ④gaining credibility with their users, who expect authentic opinions when making decisions. Ultimately, the power of online reviews depends entirely on their perceived ⑤honesty.

Food poisoning cases increase sharply during the hot summer months. High temperatures allow bacteria to grow ①quickly in food that is not stored properly. Always wash your hands with soap before preparing food, since this habit ②reduces the risk of infection. Make sure that meat and eggs are cooked ③thoroughly, since undercooked food can carry harmful bacteria. Keep perishable food ④cold in the refrigerator, rather than leaving it out at room temperature. If you experience symptoms such as stomach pain or vomiting, you should seek medical attention ⑤rarely.

During the rainy season, umbrellas and raincoats become essential items for daily life. However, many people forget to take care of them properly, which ___________. After using a wet umbrella, let it dry fully before folding it again, since storing a damp umbrella in a closed bag can cause mold and a bad smell.

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, ___________.

This is because thirst is often a sign that your body is already dehydrated. Drinking enough water is especially important during the hot summer months, and experts recommend drinking regularly rather than waiting until you feel thirsty. ( ① ) When you sweat a lot, your body loses not only water but also important minerals called electrolytes. ( ② ) If you do not replace these losses, you may feel tired, dizzy, or even suffer from muscle cramps. ( ③ ) It is best to avoid sugary drinks and too much caffeine, since they can make dehydration worse. ( ④ ) Instead, choose plain water or drinks that contain electrolytes, especially after exercise. ( ⑤ ) Eating water-rich fruits and vegetables can also help you stay hydrated.

주어진 문장: Without such improvements, even the most generous rewards program cannot compensate for a disappointing product. 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. ( ① ) Companies invest significant resources in loyalty programs, offering points, discounts, and exclusive access to encourage repeat purchases. ( ② ) However, some critics argue that these programs manipulate consumers into staying with a brand out of habit rather than genuine satisfaction. ( ③ ) Genuine loyalty, they contend, should be earned through consistent quality and honest treatment of customers. ( ④ ) Furthermore, excessive focus on retaining existing customers can cause companies to neglect innovation, since they assume loyal buyers will continue purchasing regardless of improvements. ( ⑤ ) As markets become more competitive, relying solely on loyalty programs without addressing underlying product quality may ultimately backfire.
