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.

Remote work has moved from a rare privilege to a common practice for millions of employees worldwide. Many companies that once required workers ①to commute daily now allow them to complete tasks from home. Supporters argue that remote work increases productivity, since employees avoid long commutes and ②distracting office environments. It also allows companies to hire talented people regardless of where they live, ③widening the pool of candidates. Critics, however, worry that remote work weakens teamwork and ④make it harder for new employees to learn from experienced colleagues. Without regular face-to-face interaction, some workers feel isolated and ⑤struggle to build strong professional relationships.

Automation is transforming labor markets more quickly than economists predicted only a decade ago. Factories once staffed by hundreds of workers now rely on robotic arms ①that assemble products with remarkable precision. Warehouses use automated systems ②to sort and deliver packages within a few hours. This shift does not simply eliminate jobs; it also creates roles that ③never exists before. Technicians who maintain robotic equipment are now in high demand, and engineers who design efficient systems ④are highly valued. Policymakers argue that retraining programs ⑤are essential to help displaced workers move into emerging fields.

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.

Modern factories increasingly rely on collaborative robots, often called cobots, which are designed to work ①safely alongside human employees. Unlike traditional industrial robots that operate behind safety cages, cobots use sensors to detect nearby workers and adjust their movements accordingly. Cobots typically handle repetitive or physically demanding tasks, while human workers focus on tasks that require ②judgment and fine motor skills. This division of labor increases overall ③efficiency, since each side contributes what it does best. Manufacturers who have introduced cobots report ④more workplace injuries, largely because employees no longer perform exhausting repetitive motions all day. As the technology becomes more affordable, smaller companies are also beginning to ⑤adopt cobots.

One common method, known as social proof, shows images of many people using or enjoying a product, suggesting that its ①popularity guarantees quality. Another technique appeals to authority, featuring experts or professionals endorsing a product to make it seem more ②credible and trustworthy. Repetition also plays a significant role, since seeing the same advertisement multiple times ③decreases familiarity, which people often mistake for reliability. Researchers studying consumer behavior have found that viewers who understand these techniques are less easily ④influenced by them, since awareness disrupts the automatic psychological response advertisers depend on. For this reason, media literacy programs increasingly teach students to ⑤recognize persuasive techniques hidden within everyday advertisements.

When Mina was a freshman, she often spent her allowance within a few days. Her older cousin told her about the marshmallow experiment, a famous study in which children could eat one marshmallow immediately or wait for two. Researchers found that children who waited longer showed better academic performance and self-control years later. This ___________ is known as delayed gratification. Inspired by the study, Mina began saving half of her allowance each week instead of spending it all on snacks.

The gig economy, in which people take on short-term or freelance jobs instead of full-time positions, has grown rapidly over the past decade. This model offers clear advantages: workers can choose when and how much they work, and businesses can hire help only when they actually need it. For many young people entering the job market, gig work provides valuable flexibility that traditional employment rarely allows. However, gig workers often ___________, which full-time employees typically receive. Because their income can fluctuate sharply from month to month, many gig workers struggle to plan their finances confidently.

Many teenagers check their social media accounts dozens of times a day, worried that they might miss something important happening among their friends. This anxiety, known as FOMO, or the fear of missing out, arises when people believe that others are enjoying experiences from which they themselves are excluded. For example, a student scrolling through photos of a party she was not invited to may suddenly feel a wave of loneliness and regret, even though the event has already ended. Constantly refreshing feeds to avoid missing such updates, however, makes it difficult to concentrate on schoolwork or conversations happening in the present moment. Moreover, this endless comparison with curated highlights of other people's lives tends to deepen feelings of anxiety rather than relieve them. Therefore, students should learn to ___________.

Parents and coaches sometimes worry that heavy resistance training might damage the growth plates in a young athlete's bones, cartilage regions near the ends of long bones responsible for lengthening as a child develops. (A) This concern kept strength training out of many youth programs for decades. (B) However, extensive research over the past twenty years has found little evidence that properly supervised resistance training harms growth plates in healthy children. (C) The actual risk, researchers now believe, arises not from lifting weights itself but from poor technique, excessive load, and inadequate supervision.
