Anthropologist Robin Dunbar proposed a concept now known as Dunbar's number, suggesting that human beings can only ①abandon about one hundred fifty stable social relationships at any given time. This limit, he argued, comes from the size of the human brain, which ②restricts 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 are ④close 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 largely ⑤unnoticed.

Planning a multi-city trip once meant hours spent comparing flight schedules, reading hotel reviews, and mapping out which sights were close enough to visit in a single day. AI travel planners now ①compress much of that work into a short conversation, asking about a budget, a travel style, and a handful of preferences before generating a full day-by-day itinerary within minutes. The tool draws on enormous amounts of data to suggest a route that avoids obvious ②scheduling conflicts. Many travelers appreciate having a solid starting point rather than a ③blank page. Still, seasoned travelers warn that these itineraries can feel oddly ④unique, often steering users toward the same popular landmarks that every other AI-generated plan recommends, while ⑤overlooking smaller, lesser-known places that a knowledgeable local guide might have suggested instead.

Long before cognitive scientists possessed the tools to observe the brain directly, Donald Broadbent proposed an influential model suggesting that the human capacity to process incoming sensory information is ①constrained by a structural bottleneck through which only a single stream of input can pass at any given instant. According to this filter theory, multiple channels of stimulation, such as competing voices in a crowded room, are initially registered at a ②deep, physical level, but only one channel is selected for further, meaning-based analysis while the rest are blocked from advancing beyond that early filter. Although later researchers challenged the ③rigidity of this early selection mechanism, pointing to instances in which unattended information, such as one's own name, nevertheless breaks through and captures awareness, the core insight that attention imposes a genuine processing limit rather than a mere matter of willpower has remained remarkably ④durable. This basic bottleneck principle continues to inform contemporary explanations of why multitasking so reliably ⑤degrades performance on demanding tasks.

Long before calculus existed, the Greek philosopher Zeno constructed a series of paradoxes designed to show that motion itself might be logically impossible. In one version, a swift runner named Achilles races a slow-moving tortoise that is given a modest head start. Common sense insists that Achilles will quickly overtake the tortoise, yet Zeno's argument suggests otherwise. By the time Achilles reaches the tortoise's starting point, the tortoise has crawled a little further ahead; by the time Achilles closes that new gap, the tortoise has advanced again, however slightly. This process repeats endlessly, generating _______________. Zeno concluded that Achilles could never actually catch the tortoise, a conclusion that plainly contradicts everyday experience.

Sleep is not a single, uniform state but a cycle that alternates between two very different modes: REM (rapid eye movement) sleep and non-REM sleep. During non-REM sleep, especially its deepest stage, the brain waves slow down dramatically, the body temperature drops, and tissue repair and growth hormone release reach their peak. This is the period most closely associated with physical restoration. REM sleep, by contrast, brings rapid eye movements, near-total muscle paralysis, and brain activity that closely resembles wakefulness. Most vivid dreaming occurs during this stage, and researchers believe _______________. A healthy night typically cycles through both stages four or five times, with non-REM dominating the early hours and REM periods lengthening toward morning. Disrupting either stage, through frequent awakenings or alcohol use, can leave a person feeling unrested even after a full night in bed.

Labeling theory approaches deviance not as a fixed property of certain acts, but as a social process created when powerful groups attach a negative label to a person's behavior. According to this view, nearly everyone breaks minor rules at some point, yet only some individuals are singled out, caught, and formally branded as delinquents or criminals. Sociologist Howard Becker argued that this label often becomes a master status, a single identity that overshadows every other trait a person has. Once labeled, an individual may find legitimate opportunities closing off, pushing them toward _______________. This process, sometimes called secondary deviance, illustrates how social reaction can produce the outcome it claims merely to describe.

Walking down a crowded street while staring at a phone screen has become such a common sight that it barely draws attention anymore, even though the habit turns a pedestrian into one of the least alert people on the sidewalk. (A) Hospitals have reported a steady rise in injuries linked to distracted walking, ranging from minor scrapes after tripping over a curb to serious collisions with moving vehicles at intersections. (B) Researchers who study attention describe this as a kind of tunnel vision: a person absorbed in a text message or a video processes only a narrow slice of the surrounding environment. (C) What makes this danger especially difficult to address is that pedestrians rarely recognize the risk in the moment; unlike distracted driving, which is widely condemned, glancing at a phone while crossing the street still feels like a harmless habit.

This mismatch between internal time and local time is the true source of the problem, not the flight itself. Travelers who cross several time zones in a single flight often arrive feeling exhausted, foggy, and strangely out of sync with the local clock, a condition widely known as jet lag. ( ① ) The discomfort arises because the body's internal clock, which governs sleep, hunger, and alertness, continues to run on the schedule of the departure city even after landing. ( ② ) Realigning this internal clock to a new time zone is not instantaneous; researchers estimate that the body typically needs about one day to adjust for every time zone crossed. ( ③ ) Flying eastward tends to produce more severe symptoms than flying westward, because advancing the internal clock forward is generally harder for the body than delaying it. ( ④ ) Exposure to natural light at the right moments after arrival can help speed up the adjustment, since light is the strongest external cue the internal clock uses to reset itself. ( ⑤ ) Without such adjustments, travelers may continue to experience disrupted sleep and reduced concentration for several days after a long international flight.

This loss, many say, is not simply about the words themselves but about a physical sense of place within the story. Whenever people discuss the future of reading, one debate never seems to end: e-books or paper books? ( ① ) Supporters of e-books point out that a single device can hold thousands of titles, which makes traveling with a full library incredibly light. Readers can also change the font size, look up a word instantly, and carry their entire collection in one bag. ( ② ) Fans of paper books, however, argue that something important is lost on a screen. ( ③ ) Many readers say they remember a paper book's plot more clearly, perhaps because they recall where a scene appeared on the page. ( ④ ) Screens also invite distraction, since a single notification can pull a reader away from the story in seconds. ( ⑤ ) Interestingly, several recent surveys suggest that most young readers do not choose one format forever. Instead, they switch between paper and digital depending on the situation, treating the debate less as a contest and more as a matter of convenience.

주어진 문장: In other words, the record shows how a student thought and acted, not merely which club they joined. Many students wonder why club activities matter so much for their school life record, a document that summarizes what a student did during each semester. ① Whenever students take part in a club, their teacher writes a short note describing what role they played and how they grew. ② For example, a student who organized a club exhibition might be described as someone who showed strong leadership and creativity. These notes are not simply a list of activities; they explain the process behind each achievement. ③ Therefore, admissions officers at universities read the record carefully to understand a student's genuine interests, not just their grades. In contrast, a club membership with no real participation rarely leaves a meaningful impression. ④ This is why teachers encourage students to take an active role rather than joining a club only for its name. ⑤
