Opening most camera apps today reveals a row of filters that can smooth skin, brighten eyes, and reshape a jawline before a photo is even taken, all powered by AI models ① trained to recognize facial features in real time. What began as a playful novelty has become a default setting for many users, subtly ② adjusting nearly every selfie posted online. Psychologists have grown concerned about a specific consequence of this shift: people increasingly compare their unfiltered reflection in a mirror to a filtered version of themselves ③ seeing constantly on a screen, a comparison that earlier generations never had to face. Some social media platforms have responded by ④ labeling heavily edited photos or banning certain filters that alter body shape. Whether such small warnings can meaningfully counter the daily flood of filtered images, however, ⑤ remains an open question that researchers are only beginning to study.

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

An echo chamber refers to an online environment where people are mainly ①exposed to opinions that already match their own beliefs. This phenomenon occurs because social media algorithms tend to ②recommending content similar to what users have previously liked or shared, gradually narrowing the range of perspectives they encounter. As a result, individuals inside an echo chamber rarely engage with viewpoints ③that challenge their existing assumptions, which allows their original beliefs to grow increasingly extreme over time. For example, someone who frequently reads articles supporting one political party may begin to see the opposing party as entirely unreasonable, ④having never seriously considered its arguments. Political polarization, a significant issue in many countries today, is often ⑤linked to this pattern of selective exposure.

Climate scientists frequently warn about tipping points, thresholds beyond which a small additional change triggers a large, often irreversible shift in the climate system. Unlike ①gradual warming, which unfolds steadily over decades, crossing a tipping point can produce ②dramatic consequences within a short period. For instance, as Arctic ice melts, it exposes darker ocean water that absorbs more sunlight than reflective ice, accelerating further melting in a self-⑤reinforcing cycle. Similarly, scientists worry that a major ocean current, which currently redistributes heat across the planet, could slow dramatically if enough freshwater from melting glaciers dilutes the surrounding seawater. Once such thresholds are crossed, restoring the original balance may become nearly ③possible, even if emissions are later reduced. Therefore, researchers argue that preventing these transitions matters more than merely slowing average temperature increases. Identifying how close each system stands to its threshold remains one of the most ④urgent challenges in climate research.

On a summer evening, downtown streets often feel noticeably hotter than nearby parks or suburban neighborhoods, even after the sun has set. This phenomenon, known as the urban heat island effect, occurs when _______________. Unlike soil or vegetation, which absorb and release heat gradually, these man-made surfaces absorb sunlight during the day and slowly radiate it back at night, preventing temperatures from cooling. Tall buildings packed closely together also block wind, trapping warm air within narrow streets. In contrast, areas with abundant trees and open water naturally stay cooler, since plants release moisture that helps lower surrounding temperatures. To reduce this effect, many cities have begun installing rooftop gardens and expanding public parks, hoping that additional greenery will absorb less heat than pavement does.

When a customer opens a company's website at midnight with a billing question, an actual employee is unlikely to be available, which is exactly the gap that customer service chatbots were built to fill. These programs can instantly answer common questions, track packages, and process simple refunds without making anyone wait on hold. Yet the technology has clear boundaries. When a customer's problem is unusual, emotionally charged, or simply does not fit the chatbot's script, _______________. Many companies have responded by designing chatbots to recognize their own limits, automatically transferring a frustrated customer to a human agent.

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. 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, since _______________. 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 and may even reduce the perceived soreness that follows a hard session.

Many people believe that a new habit becomes automatic after only twenty-one days, but researchers who examined real behavior found a different number. This project, called the 66-day habit formation study, tracked volunteers who tried to adopt a new daily habit, like drinking water with lunch. Researchers measured how automatic each action felt over time and found that habits needed ___________. Yet the actual time varied widely, ranging from about eighteen days for simple habits to over two hundred days for difficult ones. This wide range explains why the popular twenty-one-day claim, though easy to remember, rarely matches real experience.

Habit researchers often note that people overestimate the role of motivation in daily routines. (A) As a result, they frequently give up soon after starting, blaming themselves for lacking discipline. (B) In contrast, Fogg's framework suggests that shrinking the task itself is more effective than boosting motivation. (C) Because motivation naturally rises and falls, relying on it alone often leads to inconsistent effort.

주어진 문장: In contrast, downward comparison, which involves comparing oneself with someone worse off, can temporarily boost self-esteem instead. Psychologist Leon Festinger introduced social comparison theory, which explains that people evaluate their own abilities and opinions by comparing themselves with others. ( ① ) According to this theory, individuals engage in upward comparison when they measure themselves against someone who appears more successful, attractive, or accomplished. ( ② ) Social media platforms, filled with carefully edited photos and exaggerated achievements, provide endless opportunities for this kind of comparison. ( ③ ) For instance, a teenager browsing vacation pictures posted by classmates may begin to feel that her own ordinary life is somehow inadequate. ( ④ ) Unlike comparing oneself with someone in a similar position, which can sometimes boost confidence, upward comparison frequently triggers envy, dissatisfaction, and lower self-esteem. ( ⑤ ) Researchers have found that frequent upward comparison online is linked to higher depression and anxiety. Consequently, this theory helps explain why scrolling through social media often leaves users feeling worse rather than better about themselves.
