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.

For decades, productivity advice has focused almost entirely on managing time efficiently, yet many experts now argue this approach ①emphasizes something important. Unlike time, which flows at a ②constant rate, human energy naturally rises and falls in cycles shaped by sleep, food, and mental fatigue. A person who tackles difficult tasks during a low-energy period, for instance, may need two hours to finish what takes thirty minutes at ③peak energy. Similarly, someone who forces themselves to keep working without rest often produces careless mistakes that require additional time to ④correct later. Advocates of energy management recommend identifying one's peak hours and reserving them for demanding work, while saving low-energy periods for ⑤routine tasks.

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

After a strenuous workout, muscle fibers experience thousands of microscopic tears, and the body immediately begins a repair process that depends heavily on amino acids, the building blocks that protein supplies. This is why sports scientists recommend consuming protein within a couple of hours after training, since _______________. Many athletes assume that eating an enormous quantity of protein in a single sitting will speed up this process, but the body can only use a limited amount at once; the rest is simply burned for energy or stored as fat.

Have you ever noticed that an unfinished task keeps returning to your mind long after you stopped working? This phenomenon was first noticed by psychologist Bluma Zeigarnik, who saw that waiters remembered unpaid orders better than paid ones. Her observation led to what is now called the Zeigarnik effect: ___________. According to this theory, the mind maintains mental tension until a task reaches closure, keeping the unfinished task active in memory.

Across many countries, high schools begin classes early in the morning, often before eight o'clock. This schedule assumes that teenagers can simply go to bed earlier to compensate, but biology tells a different story. During adolescence, the body's internal clock shifts later, delaying the release of melatonin until well after ten at night. As a result, most teenagers are not physiologically ready to fall asleep until much later than younger children or adults. When early start times force them to wake before their bodies have completed a full sleep cycle, the mismatch accumulates into a chronic sleep debt that affects concentration and mood throughout the school day. Researchers who study this mismatch argue that _______________. Some school districts that delayed their start times by thirty minutes reported improvements in attendance, suggesting that the timing of the school day matters more than commonly assumed.

After an especially demanding training session, the instinct to collapse onto a couch and remain motionless is understandable, yet exercise physiologists increasingly recommend the opposite approach. (A) This gentle activity keeps blood circulating through tired muscles, which appears to help clear metabolic byproducts more efficiently than complete stillness does. (B) Some athletes worry that any movement at all will interfere with the repair process, but research suggests that truly light activity does not meaningfully slow healing. (C) Active recovery involves performing low-intensity movement, such as a light jog, an easy swim, or a gentle bike ride, on days following intense exertion rather than resting completely.

Aerobic exercise, such as jogging, swimming, or cycling at a steady pace, produces a wide range of benefits that extend well beyond simple calorie burning. (A) This adaptation explains why trained athletes often have a much lower resting heart rate than sedentary individuals of the same age. (B) Over weeks of consistent training, the heart gradually enlarges and becomes more efficient, delivering the same amount of oxygen to working muscles while beating fewer times per minute. (C) Most fundamentally, it strengthens the heart itself, forcing it to pump larger volumes of blood with each beat.

Every day, email providers quietly block billions of unwanted messages before they ever reach a user's inbox, a task that would be impossible without an AI filtering system running constantly in the background. (A) This creates a constant back-and-forth, since spammers study which messages get blocked and then adjust their wording to slip through again. (B) The filter examines each incoming message for suspicious patterns, including certain keywords, unusual sender addresses, and formatting tricks that scammers commonly rely on to slip past detection. (C) What makes the system effective is that it keeps learning after launch, since a user's action of marking or rescuing a message becomes new training data.

주어진 문장: Recognizing this complexity is the first step toward more responsible journalism. The framing effect describes how people respond differently to the same information depending on how it is presented, even when the underlying facts remain unchanged. ( ① ) When news outlets describe climate change primarily as a looming crisis, filled with images of disasters and warnings of irreversible damage, audiences often react with fear or, paradoxically, with hopeless resignation. ( ② ) In contrast, when the same issue is framed as an opportunity, emphasizing innovative technologies and emerging green jobs, readers tend to feel more motivated to act and support policy change. ( ③ ) Neither framing alone tells the complete story, since climate change genuinely involves both serious risks and promising solutions. ( ④ ) Therefore, journalists who rely too heavily on either extreme risk distorting public understanding and discouraging meaningful engagement. ( ⑤ ) A balanced approach, which honestly presents dangers while highlighting realistic paths forward, is far more likely to sustain long-term public attention and inspire lasting action.
