Online advertising algorithms analyze enormous amounts of user data ①to determine which products a person is most likely to purchase. Every click, search, and pause while scrolling provides information that these systems use ②to refine future advertisements. Supporters argue that this level of precision benefits consumers by ③reducing 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 ④is specifically designed to identify and exploit individual weaknesses. Greater transparency, many experts argue, would allow consumers ⑤to make more informed decisions about their own online behavior.

Building brand loyalty has traditionally been considered one of the most valuable goals in marketing, since loyal customers ①tend to spend more and recommend products to others. Companies invest significant resources in loyalty programs, ②offering points, discounts, and exclusive access to encourage repeat purchases. Genuine loyalty, critics contend, should be earned through consistent quality and honest treatment of customers, not through artificial incentives that merely ③delays a customer's departure. Furthermore, excessive focus on retaining existing customers can cause companies ④to neglect innovation, since they assume loyal buyers will continue purchasing regardless of improvements. Relying solely on loyalty programs without addressing underlying product quality may ultimately ⑤backfire.

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.

Biodegradable plastics have been promoted as a ①promising solution to plastic waste, since they are designed to decompose into natural substances rather than persist for centuries. Manufacturers derive these materials from renewable resources such as corn starch, blending them with additives that ②accelerate microbial breakdown once discarded. However, their environmental benefits are often exaggerated, largely because decomposition depends on specific conditions rarely found outside industrial composting facilities. For example, a bag labeled biodegradable may take years, not the weeks advertised, to break down in a landfill or ocean, where temperature and microbial activity remain ③high. In addition, when mixed with conventional plastics in recycling streams, they can ④contaminate the process, weakening the quality of materials produced afterward. Some engineers therefore compare biodegradable plastics to a bridge that leads nowhere unless paired with infrastructure that completes the journey. Ultimately, realizing their ⑤genuine potential requires not only technological refinement but also facilities capable of providing the precise conditions decomposition demands.

Many students set a New Year goal to build a new habit. However, most people give up within two weeks because the habit still feels ①easy. Researchers found that, on average, a new habit takes about sixty-six days to feel automatic. During the first few weeks, your brain still treats the activity as something ②new, so you must rely on willpower. Around the middle of this period, the behavior becomes ③easier because your brain starts to expect it at a certain time each day. By the end, you no longer need to force yourself, since the action feels ④natural and comfortable. This is why experts suggest repeating a small action every day, rather than aiming for a perfect performance ⑤right away.

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.

When people have no specific goal, they usually feel ①confused about where to start, and their interest fades within days. For example, a student who simply decides to study harder this year often loses direction because the plan is too ②vague. In contrast, a student who sets a ③clear goal knows exactly what to do every day. A clear goal also makes progress easy to measure, and noticing small improvements keeps people ④encouraged. Setting a specific goal is one of the most ⑤ineffective ways to build lasting motivation.

Many households save far less for retirement than conventional financial advice would recommend. Some economists have proposed a savings program in which employees commit today to allocating a portion of their future salary increases toward retirement savings, rather than being asked to reduce their current take-home pay immediately. Field trials of such programs have reported substantial increases in average savings rates. This approach demonstrates that savings policy grounded in realistic assumptions about human psychology can prove considerably more ___________ than policy grounded in the assumption that individuals will always act in strict accordance with their own long-term rational interests.

Not long ago, Junho felt he needed to check his phone every few minutes just to keep up with his friends. (A) During this unplanned break from his phone, he was surprised to discover that he actually felt calmer rather than anxious. (B) Encouraged by this experience, he began setting aside phone-free hours on purpose, gradually growing comfortable with being offline. (C) This constant checking left him drained, until one day his phone battery died unexpectedly during a trip.

주어진 문장: This is why many coaches encourage athletes to keep their pre-game rituals exactly the same, even when circumstances change. Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. ( ① ) This theory explains that every habit begins with a cue, a signal that tells the brain to start an automatic behavior. ( ② ) The brain then performs a routine, which is the action itself, whether physical or mental. ( ③ ) Finally, the brain receives a reward, a positive feeling that makes it want to repeat the same behavior. ( ④ ) For example, a notification sound can act as a cue that leads a student to check a phone, and the relief from boredom becomes the reward. Similarly, opening a refrigerator out of habit rather than hunger shows how a routine can run without conscious thought. Because this loop operates automatically, breaking a bad habit requires changing the routine while keeping the same cue and reward. ( ⑤ ) Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.
