문제 1

When Minji was in ninth grade, she ①posted a joking comment mocking a classmate's photo, never imagining anyone would remember it later. Three years passed, and she nearly forgot the comment ②existed, buried among hundreds of old posts. Last spring, she applied to join her school's student council, ③hoping her leadership experience would impress the selection committee. During the interview, however, one teacher mentioned ④having seen an old, unkind comment under Minji's name while reviewing applicants' profiles. She understood that digital footprints rarely disappear completely, even when the original posts ⑤was removed, because screenshots and memories often outlast the content itself.

문제 2

When Mina graduated from college five years ago, she had never even heard the term "data scientist." She had studied statistics simply because she ①enjoying solving puzzles with numbers. Everything changed when a small tech startup, ②which was building an app to predict traffic patterns, hired her to analyze massive amounts of data. Mina quickly discovered that she loved ③turning raw numbers into insights that helped real people make better decisions. Within two years, demand for professionals like her ④had exploded, as companies in every industry realized how valuable data could be. Today, Mina leads a team of ten analysts, ⑤mentoring young graduates who are drawn to a field that barely existed.

문제 3

Social psychologists describe a phenomenon called the bystander effect, in which individuals become less likely ①helping a victim as the number of witnesses increases. Each observer assumes someone else will step in, and this diffusion of responsibility leaves no one ②willing to act. Cyberbullying magnifies this problem, since a single humiliating post can be witnessed by thousands of people ③scattered across the internet rather than a few standing nearby. Anonymity intensifies the effect further, allowing silent observers ④to scroll past cruel comments without feeling accountable for their inaction. Some bystanders even worry that intervening publicly might make them the bully's next target, so they choose ⑤to remain silent instead.

문제 4

An echo chamber refers to an online environment where people are mainly exposed to opinions that already ①match their own beliefs. This phenomenon occurs because social media algorithms tend to recommend content similar to what users have previously liked or shared, gradually ②narrowing the range of perspectives they encounter. As a result, individuals inside an echo chamber ③frequently engage with viewpoints that 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 ④unreasonable, having never seriously considered its arguments. Political polarization, a significant issue in many countries today, is often linked to this pattern of ⑤selective exposure.

문제 5

Automation is transforming labor markets more ①quickly than economists predicted a decade ago. Factories once staffed by hundreds of workers now rely on robotic arms that assemble products with remarkable ②precision. This shift does not simply eliminate jobs; it also creates roles that never existed before, so technicians who maintain robotic equipment are now in high ③demand. Companies that invested early in automation often report steady increases in productivity, since machines handle repetitive tasks while employees focus on ④creative problem-solving. Without proper retraining support, the benefits of automation may not be shared fairly, ⑤narrowing inequality between skilled and unskilled labor.

문제 6

For decades, athletes were taught to stretch a muscle and hold the position before any competition, believing that this practice alone would prevent injury. (A) Recent research, however, has complicated that assumption, since static stretching can actually reduce a muscle's ability to generate explosive force immediately afterward. (B) Dynamic stretching, by contrast, involves controlled, repeated movement through a joint's full range of motion and appears to prepare muscles for activity without this weakening effect. (C) As a result, many coaches now recommend saving static stretching for after a workout while reserving dynamic movements for the warm-up period before intense effort begins.

문제 7

Long before social media existed, people naturally clustered into groups based on shared traits. (A) These algorithms track patterns such as shared interests, mutual friends, and browsing habits to recommend new connections. (B) Neighborhoods, schools, and workplaces often reflected this tendency, as individuals gravitated toward others who resembled themselves. (C) Today, however, this same tendency operates through recommendation algorithms built into social media platforms.

문제 8

주어진 문장: She was surprised at how little willpower this required once the routine became familiar. Minji had tried for years to build a bedtime reading habit but always forgot once under the blanket. ( ① ) During summer, she found a method called habit stacking. It means attaching a new habit to an existing one so it acts as a reminder. ( ② ) Her existing habit was brushing her teeth every night, so she decided to place her book beside her toothbrush. ( ③ ) After brushing her teeth, she would pick up the book, letting one action trigger the next. ( ④ ) Within two weeks, opening the book after brushing felt almost automatic, requiring no conscious effort. ( ⑤ ) Encouraged by this success, Minji stacked another habit onto her morning routine, reviewing vocabulary words after making her bed.

문제 9

주어진 문장: This is why many coaches encourage athletes to keep their pre-game rituals exactly the same, even when circumstances change. Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. ( ① ) This theory explains that every habit begins with a cue, a signal that tells the brain to start an automatic behavior. ( ② ) The brain then performs a routine, which is the action itself, whether physical or mental. ( ③ ) Finally, the brain receives a reward, a positive feeling that makes it want to repeat the same behavior. ( ④ ) 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 changing the routine while keeping the same cue and reward. ( ⑤ ) Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.

문제 10

주어진 문장: Not every transaction goes smoothly, however, since photographs and descriptions cannot always capture an item's true condition. Secondhand trading platforms, once considered a niche market for used goods, have grown into a mainstream part of consumer culture. ( ① ) Rising prices for new products, combined with growing awareness of environmental waste, have encouraged many shoppers to consider used items before purchasing something brand new. ( ② ) These platforms allow individuals to sell clothing, electronics, and furniture directly to other consumers, cutting out traditional retail markups entirely. ( ③ ) For younger buyers especially, purchasing secondhand items has become associated with resourcefulness rather than financial necessity. ( ④ ) Sellers benefit as well, earning extra income from items that would otherwise sit unused in storage. ( ⑤ ) To address this problem, many platforms now offer buyer protection programs and detailed rating systems for sellers.
