Caffeine is the most widely consumed stimulant in the world, ①prizing for its ability to sharpen focus and fight off fatigue within minutes of consumption. It works by blocking adenosine, a chemical that gradually builds up in the brain throughout the day and ②makes us feel increasingly sleepy the longer we stay awake. By occupying the receptors that adenosine would normally bind to, caffeine tricks the brain into ③feeling alert even when the body has accumulated significant sleep pressure. The effects, however, last far longer than most people realize. Because caffeine can remain active in the bloodstream for five to six hours, a cup of coffee ④consumed in the late afternoon may still be interfering with the ability to fall asleep at midnight. Even when people do not consciously notice difficulty falling asleep, caffeine has been shown ⑤to reduce the amount of deep, restorative sleep obtained later in the night.

Generation Z, typically defined as those born between the late 1990s and early 2010s, approaches shopping quite differently from previous generations. ①Having grown up with smartphones and social media, they research products extensively online before making even small purchases. Unlike older generations, ②who often valued brand loyalty above all else, many members of Generation Z prioritize a company's values. They also tend to favor secondhand and resale platforms, ③viewing sustainability as an important factor rather than an afterthought. Peer recommendations ④shared through short videos frequently ⑤carries more weight than traditional celebrity endorsements, since viewers see these creators as relatable rather than distant figures.

Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. This theory explains that every habit ①begins with a cue, a signal that tells the brain to start an ②automatic behavior. The brain then performs a routine, which is the action itself, whether physical or mental. Finally, the brain receives a reward, a ③negative feeling that makes it want to ④repeat the same behavior. 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 almost without ⑤conscious thought. Because this loop operates automatically, breaking a bad habit requires changing the routine while keeping the same cue and reward. Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.

Time blocking is a time-management technique in which a person divides the day into fixed blocks. Each block is then assigned to a single task. Instead of relying on a loose to-do list, the person decides exactly when each task will start and end. This approach ①lowers the mental effort of deciding what to do next, since the schedule already provides the answer. It also ②limits multitasking, because each block is reserved for only one activity at a time. For instance, a student may block ninety minutes for math practice, leaving no room for messages or web browsing. Because each block has a ③vague boundary, unfinished work is ④less likely to quietly spread into the next task. Many people who adopt time blocking feel ⑤more organized throughout the day.

Many companies now advertise themselves as environmentally responsible, yet a growing number of these claims turn out to be ①misleading. This practice, known as greenwashing, occurs when a business spends more effort marketing its products as eco-friendly than actually reducing environmental harm. A company might launch a recycled-packaging line while continuing to pollute rivers through its main factories, creating a false impression of genuine change. Such tactics ②deceive well-intentioned consumers who wish to shop responsibly but lack the tools to ③verify corporate claims. In contrast, truly sustainable businesses publish detailed, independently verified data about their emissions and supply chains, allowing outsiders to check their progress. Therefore, shoppers should look beyond vague labels like green or natural and instead search for ④recognized certifications, transparent reports, and measurable targets. Without such scrutiny, greenwashing will keep ⑤declining, undermining public trust and slowing the broader shift toward an economy that truly protects the planet.

Last January, Minji wrote the same resolution she always wrote: study English for an hour every day. 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 ___________. This idea, developed by psychologists, means forming a specific if-then plan that links a certain situation to a certain action in advance. Instead of vaguely intending to study more, Minji made a precise plan: if she finished dinner, then she would study for thirty minutes.

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 ___________.

Only a decade ago, translation apps produced sentences so awkward that users often laughed at the results rather than trusting them. (A) Frequent travelers now point their phone cameras at street signs and receive an instant translation overlaid on the screen, thanks to this leap in accuracy. (B) Even so, the technology still struggles with humor, sarcasm, and cultural nuance, areas where a single wrong word can completely change the intended meaning. (C) Today, many of these apps rely on neural networks that analyze entire sentences at once, capturing context instead of translating word by word.

주어진 문장: She walked into the interview room feeling confident, certain that her past online activity had nothing to do with her qualifications. When Minji was in ninth grade, she posted a joking comment mocking a classmate's photo, never imagining anyone would remember it later. ( ① ) Three years passed, and she nearly forgot the comment existed, buried among hundreds of old posts. ( ② ) Last spring, she applied to join her school's student council, hoping her leadership experience would impress the selection committee. ( ③ ) During the interview, however, one teacher mentioned having seen an old, unkind comment under Minji's name while reviewing applicants' profiles. ( ④ ) Startled, Minji realized that everything she had ever posted online had quietly accumulated into what is called a digital footprint, a lasting trail of personal data left behind by online activity. ( ⑤ ) Although she deleted the comment immediately, the damage to her reputation had already been done. She understood that digital footprints rarely disappear completely, even when the original posts are removed, because screenshots and memories often outlast the content itself.

주어진 문장: At first glance, this seems to suggest that Dunbar's theory no longer applies in the digital age. Anthropologist Robin Dunbar proposed 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. ( ① ) This limit, he argued, comes from the size of the human brain, which restricts how many meaningful connections a person can cognitively manage. ( ② ) In contrast, many social media users today have hundreds or even thousands of online friends and followers, a number far exceeding what Dunbar's research predicts. ( ③ ) However, having numerous digital contacts does not necessarily mean that all of these relationships are close or emotionally supportive. ( ④ ) Most users, when asked, admit that they interact regularly with only a small fraction of their total followers, while the rest remain largely unnoticed. ( ⑤ ) Therefore, Dunbar's number reminds us that genuine, lasting relationships require consistent effort and attention, something that a large online network alone cannot provide.
