During sleep, the brain does not simply rest; it actively reorganizes the day's experiences into lasting memories through a process called consolidation. Newly formed memories are initially fragile and ① store primarily in a brain region called the hippocampus, ② which has limited long-term capacity. While a person sleeps, particularly during the deep stages of non-REM sleep, neural activity replays these fresh memory traces in rapid, compressed sequences, gradually ③ transferring the information to the cortex for more durable, long-term storage. This replay strengthens the connections between neurons that encoded the original experience, ④ making the memory more resistant to interference from unrelated events the following day. Sleep researchers have demonstrated this effect experimentally: participants who slept after ⑤ learning a list of word pairs recalled more items the next day than participants who remained awake instead.

Sociologist Mark Granovetter introduced an idea that seems ①contradictory at first glance, known as the strength of weak ties. According to this theory, people who see each other only ②occasionally, called weak ties, often provide 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 ③similar knowledge. Weak ties, in contrast, move within different networks, which allows 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 ④harder, letting users keep hundreds of loose acquaintances active without frequent face-to-face meetings. Consequently, these platforms function as efficient channels through which weak ties continue delivering ⑤fresh opportunities that close relationships simply cannot offer.

Many companies today advertise their products as environmentally friendly, yet not all of these claims are accurate. This practice, known as greenwashing, involves exaggerating or fabricating a product's positive impact on the environment. Some brands print vague terms such as "natural" or "eco-conscious" on packaging without providing any evidence to support these labels. Consumers, who are increasingly concerned about climate change, often trust such claims without questioning them closely. As a result, they may pay higher prices for products that are no more sustainable than ordinary alternatives. Genuine environmental efforts, which usually require significant investment and long-term planning, are far more costly than simply changing a label. Therefore, governments should establish clear standards that require companies to ___________.

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 ___________.

Telemedicine has sparked debate among healthcare professionals about its proper role in modern medicine. (A) Critics counter that virtual visits cannot fully substitute for physical examinations, which remain essential for diagnosing certain conditions accurately. (B) Most experts, weighing both sides, conclude that telemedicine works best as a complement to, rather than a replacement for, traditional care. (C) Supporters point out that virtual visits save time and extend healthcare access to patients living far from hospitals.

Minji looked forward to Jimin's livestreams every single evening without fail. (A) Eventually, at a crowded fan event, Jimin treated her exactly like any other stranger waiting in line. (B) Over time, she began to feel that the two of them shared a genuine, personal friendship. (C) That moment made Minji realize that the closeness she had felt existed only on her side.

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.

주어진 문장: This unexpected combination of skills fascinated him more than he had expected. When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers belonged only to a handful of government scientists. ( ① ) By the time he entered university, however, the space industry had changed dramatically, as private companies began launching satellites and building reusable rockets. ( ② ) Daniel studied aerospace engineering, drawn to the idea that space exploration was no longer limited to a few national agencies. ( ③ ) During an internship, he helped design a small satellite intended to monitor crop health from orbit, a project that combined engineering with agricultural science. ( ④ ) He realized that the space industry now needed not only pilots and engineers but also data analysts, technicians, and even lawyers familiar with international space regulations. ( ⑤ ) After graduation, Daniel joined a startup developing lunar landing equipment, a job that barely existed when he first imagined his future career.

주어진 문장: Yet this same tendency also carries a hidden drawback. Sociologists use the term homophily to describe the tendency of people to form connections with others who share similar backgrounds, opinions, or interests. ( ① ) This principle explains why classmates from the same major often become close friends, while coworkers with shared hobbies naturally gravitate toward one another. ( ② ) Because similarity reduces the effort required to understand another person's perspective, relationships built on shared traits tend to feel comfortable and require less negotiation. ( ③ ) However, this same comfort can narrow the range of viewpoints someone encounters, since surrounding oneself with similar people limits exposure to different ideas. ( ④ ) Social media platforms intensify this pattern through recommendation algorithms that suggest new friends based on shared interests or similar browsing history. ( ⑤ ) As a result, users often find their online circles becoming increasingly homogeneous, filled with people who think and behave much like themselves.

주어진 문장: Researchers have found that people who use this method are significantly more likely to follow through on their goals than those who rely on willpower alone. Last January, Minji wrote the same resolution she always wrote: study English for an hour every day. ( ① ) By February, she had already quit, just as in previous years. Frustrated, she asked her teacher why her willpower always failed, and learned about a concept called implementation intentions. ( ② ) This idea, developed by psychologists, means forming a specific if-then plan that links a certain situation to a certain action in advance. ( ③ ) Instead of vaguely intending to study more, Minji made a precise plan: if she finished dinner, then she would study for thirty minutes. ( ④ ) She also prepared a backup plan: if she felt too tired, then she would study for just ten minutes instead of skipping entirely. ( ⑤ ) Because these plans removed the need to decide anything in the moment, starting became far easier for Minji. By December, she had studied for eleven straight months, proving that clear if-then plans beat vague intentions.
