Psychologists have long studied a mechanism called the variable reward schedule, in which rewards ①arrive unpredictably rather than after every single action. Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. When someone posts a photo, they cannot predict exactly when likes will appear, nor ②how many they will eventually receive. This uncertainty triggers a small burst of dopamine each time the phone ③is checked, regardless of whether the result is disappointing or thrilling. Consequently, users often refresh their feeds compulsively, ④hoping the next check will finally bring a satisfying reward. What makes this troubling is that technology companies deliberately designed notification systems using insights borrowed from gambling research, rather than ⑤stumble upon them by accident.

Artificial intelligence has begun to play a surprising role in creative industries ①once thought to be uniquely human. Programs can now compose music, generate paintings, and ②draft short stories within seconds. Some artists welcome this technology, ③used AI tools to explore new styles or overcome creative blocks that once took weeks to resolve. Others, however, argue that AI-generated art lacks the emotional depth ④that comes from genuine human experience. Therefore, artists who learn to work alongside AI, rather than compete against it, may find themselves ⑤with a distinct advantage.

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.

Psychologist Roy Baumeister proposed a concept called ego depletion theory, which suggests that willpower functions like a muscle that gradually ①strengthens after repeated use. According to this theory, every act of self-control, from resisting a snack to concentrating on difficult homework, draws from the same ②limited mental resource. As this resource becomes ③depleted throughout the day, later decisions require more effort and are more likely to fail. For instance, someone who exercises discipline avoiding distractions all morning may ④struggle to resist checking a phone by evening. Likewise, dieters report that self-control weakens sharply at night, after hours of resisting food. Some researchers argue that short breaks, adequate sleep, and blood sugar levels can help ⑤restore this depleted resource.

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.

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.

Melatonin is a hormone produced by a small gland deep within the brain, and its release follows a remarkably predictable daily pattern. Levels stay low throughout the bright hours of the day, begin rising in the evening as darkness falls, peak in the middle of the night, and then decline again as morning approaches. This rhythm is controlled primarily by light: specialized cells in the eye detect brightness and send signals that either permit or suppress melatonin production, which is why exposure to bright screens late at night can delay its release and make falling asleep more difficult. Unlike some hormones that directly cause the body to perform a task, _______________, preparing various systems to shift into a lower-energy state. Because of this signaling role, taking melatonin supplements at the wrong time can shift a person's internal clock in the opposite direction from what was intended.

Companies have discovered that ordinary advertisements no longer capture the attention of young consumers as effectively as they once did. (A) As a result, many brands now spend a large portion of their advertising budgets on influencer partnerships rather than television commercials. (B) This is because influencers build long-term relationships with their audiences, which makes recommendations feel personal rather than commercial. (C) However, brands must choose their partners carefully, since an influencer's reputation can directly affect how a product is perceived.

As the metaverse develops, entirely new categories of professional work are emerging alongside it. (A) Virtual event planners, for instance, now organize concerts and conferences that take place entirely within digital platforms. (B) Some skepticism remains, since the technology has not yet attracted the enormous user base that early predictions promised. (C) Despite this uncertainty, major companies continue to invest heavily, betting that virtual spaces will eventually rival physical venues in importance.

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.
