Aerobic exercise, such as jogging, swimming, or cycling at a steady pace, ① strengthens the heart by forcing it to pump larger volumes of blood with each beat. Over weeks of consistent training, the heart gradually enlarges and becomes more efficient, meaning it can deliver the same amount of oxygen to working muscles while ② beating fewer times per minute. This adaptation explains why trained athletes often have a much lower resting heart rate than sedentary individuals of the same age. Beyond the heart itself, aerobic activity encourages the body ③ building new capillaries within muscle tissue, improving the delivery of oxygen and nutrients at a cellular level. Researchers have also found that regular aerobic exercise ④ reduces inflammation throughout the body and improves the way cells respond to insulin. Because these benefits accumulate gradually rather than appearing overnight, most exercise physiologists recommend ⑤ maintaining a consistent routine for at least several months before expecting dramatic improvements in endurance.

Sociologist Mark Granovetter introduced an idea that seems contradictory at first glance, known as the strength of weak ties. According to this theory, people who see each other only occasionally, called weak ties, often ①provide more valuable information than close friends or family members, who are considered strong ties. This happens because strong ties tend to share the same social circles and, therefore, already possess similar knowledge. Weak ties, in contrast, move within different networks, which ②allows them to introduce ideas or opportunities that would otherwise remain unknown. For example, a former classmate rarely contacted might mention a job opening unavailable through one's immediate circle. Social media platforms have made maintaining such connections remarkably easier, letting users ③keeping hundreds of loose acquaintances active without frequent face-to-face meetings. Consequently, these platforms function as efficient channels through which weak ties continue ④delivering fresh opportunities that close relationships simply cannot ⑤offer.

These platforms allow individuals to sell clothing, electronics, and furniture directly to other consumers, cutting out traditional retail markups entirely. For younger buyers especially, purchasing secondhand items has become associated with ①resourcefulness rather than financial necessity. However, buying secondhand carries certain ②risks, 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 ③vague rating systems for sellers. As ④trust in these systems continues to grow, secondhand trading is expected to ⑤expand even further in the coming years.

Rather than displaying products in the usual manner, the team designed the space to resemble a colorful garden, inviting visitors to explore and take photographs. Lines formed outside the store within days, even though the products themselves were already available online. Curious about this success, a marketing researcher later interviewed several visitors, who explained that the temporary nature of the event made the experience feel special and worth attending in person. When the two weeks ended, the brand reported a significant ①decrease in both sales and social media followers. ②Encouraged by these results, the company ③began planning ④additional pop-up events in ⑤other cities.

Limited-edition products are goods that are released in small quantities for a ①short period of time. Many companies use this strategy because scarcity naturally ②decreases how much people desire an item. When consumers believe that a product will disappear soon, they often feel ③pressured to buy it immediately rather than wait. This excitement is ④intensified by social media, where people proudly share photos of items that others could not obtain. As a result, some shoppers later ⑤regret spending money on products they rarely use afterward.

Color plays a surprisingly powerful role in how consumers perceive brands, often shaping first impressions before a single word is read. Blue, for instance, is frequently used by financial and technology companies because it tends to evoke feelings of trust and stability. Red, in contrast, is associated with energy and urgency, which explains why it appears so often in logos for fast-food chains and clearance sales. Green typically signals freshness or environmental responsibility, making it a popular choice for organic food brands. Despite these general patterns, ___________. Marketers who ignore these cultural differences risk sending unintended messages to international audiences. For this reason, companies expanding into new markets often conduct extensive research before finalizing a logo's color scheme.

Online advertising algorithms analyze enormous amounts of user data to determine which products a person is most likely to purchase. As a result, the ads that appear on a person's screen often feel remarkably specific, sometimes referencing items browsed only minutes earlier. Supporters argue that this level of precision benefits consumers by reducing exposure to irrelevant advertisements and highlighting products they genuinely need. Critics, however, worry that constant exposure to tailored ads can encourage unnecessary spending, since algorithms are specifically designed to identify and exploit individual weaknesses. Because these algorithms operate largely without public oversight, few consumers fully understand how their personal data shapes what they eventually buy. Greater transparency, many experts argue, would ___________.

Viral marketing campaigns rarely succeed simply because a company has a large advertising budget. (A) A beverage brand, for example, spent almost nothing on production yet reached millions of viewers through a simple dance challenge. (B) Instead, such campaigns tend to succeed when they feel genuine and encourage ordinary users to participate creatively. (C) Other companies later tried to copy the idea, but most failed to capture the same spontaneous energy.

Ethical consumption has placed new pressure on companies to justify their practices publicly. (A) Yet critics point out that such reports are sometimes little more than carefully worded public relations documents. (B) In response, many corporations now publish detailed reports describing their environmental and labor practices. (C) For this reason, many experts insist that independent audits are necessary to confirm whether ethical claims are genuine.

Consumers today increasingly consider more than just price when deciding what to buy. (A) For example, many shoppers now research a company's labor practices before purchasing its products. (B) This growing awareness reflects a shift toward what is often called value-based consumption. (C) As a result, companies face increasing pressure to operate more responsibly and transparently.
