문제 1

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 ①trained to recognize facial features in real time. What began as a playful novelty has become a default setting for many users, subtly ②adjusting 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 ③seeing constantly on a screen, a comparison that earlier generations never had to face. Some social media platforms have responded by ④labeling 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, ⑤remains an open question that researchers are only beginning to study.

문제 2

Mira had lived in a coastal village since birth, watching the tide creep closer to her family's doorstep every year. When the sea finally ①swallowed the rice paddies that had fed her village for generations, her parents decided that staying was no longer possible. Together with many neighbors, they packed what little they could carry and moved inland, becoming what experts now call climate migrants, people forced to ②abandon their homes because of rising seas, droughts, or other disasters. This term, rarely used a decade ago, has become increasingly ③common as extreme weather displaces communities worldwide. Mira missed her old house terribly, yet she slowly began to build a new life in the crowded city, learning to adapt just as her ancestors once had. International organizations, however, still ④manage to agree on how to protect people like her, since climate migrants are not officially ⑤recognized as refugees under current law.

문제 3

During sleep, the brain does not simply rest; it actively reorganizes the day's experiences into lasting memories through a process called consolidation. Newly formed memories are initially ①fragile and stored primarily in a brain region called the hippocampus, which has ②unlimited long-term capacity. While a person sleeps, particularly during the deep stages of non-REM sleep, neural activity replays these fresh memory traces in rapid, compressed sequences, gradually transferring the information to the cortex for more ③durable, long-term storage. This replay strengthens the connections between neurons that encoded the original experience, making the memory more ④resistant to interference from unrelated events the following day. Sleep researchers have demonstrated this effect experimentally: participants who slept after learning a list of word pairs recalled more items the next day than participants who remained awake instead. Crucially, the benefit was not limited to simple recall; sleep also seemed to help participants ⑤extract general patterns from the material, suggesting that consolidation involves more than passive storage.

문제 4

Climate change deniers often seem to ignore evidence that contradicts their views, and psychologists have a specific explanation for this behavior. (A) For example, someone whose job depends on fossil fuels may search for reasons to doubt the data, even while insisting that they respect science. (B) This concept, called motivated reasoning, describes how people process information in ways that protect their existing beliefs and lifestyles rather than pursue objective truth. (C) Rather than being a simple failure of intelligence, this pattern reflects a well-documented psychological tendency studied for decades.

문제 5

Behavioral economists have long studied how small changes in choice environments affect human decisions. (A) Imagine a cafeteria where a healthy salad sits at eye level while fried snacks rest on a low shelf. Nobody is forbidden from choosing the snacks, yet most people quietly pick the salad instead. This simple technique illustrates a nudge, a concept from behavioral economics that gently guides people toward better choices without restricting their freedom. (B) Unlike strict regulations or heavy taxes, nudges rely on subtle changes in design rather than force. Critics argue nudges alone cannot solve large environmental problems, but combined with stronger policies, they can meaningfully shift everyday habits toward sustainability. (C) Companies and governments increasingly apply nudges to encourage sustainable consumption. For example, some hotels print reminders on towels stating that most guests reuse them, which persuades new guests to do the same and save water. Similarly, energy bills that compare a household's usage with that of efficient neighbors often lead people to reduce electricity use.

문제 6

Food choices are increasingly recognized as a powerful tool in the fight against climate change. (A) By replacing just a few meat-based meals each week with vegetables, grains, or legumes, individuals can noticeably shrink their carbon footprint without giving up meat completely. Nutritionists also emphasize that flexitarian eating is easier to maintain than full vegetarianism, because it allows flexibility rather than demanding absolute discipline. Therefore, many environmental groups now promote flexitarianism as a realistic first step, believing that gradual change, rather than sudden restriction, is more likely to spread widely across society. (B) A flexitarian is someone who mainly eats plant-based meals but occasionally includes meat or fish, unlike a strict vegetarian who avoids animal products entirely. This flexible diet has recently gained attention as a practical way to fight climate change, since raising livestock produces a significant portion of global greenhouse gas emissions. (C) Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at trapping heat in the atmosphere.

문제 7

Every cell in the human body follows an internal timer known as the circadian rhythm, a roughly twenty-four-hour cycle that governs when we feel alert and when we feel drowsy. (A) This clock is regulated primarily by a tiny cluster of neurons in the brain that responds to light entering through the eyes, signaling the body to suppress sleep hormones each morning. (B) As evening approaches and light fades, however, the same mechanism triggers the release of melatonin, a hormone that promotes drowsiness. (C) Because this rhythm evolved around the natural cycle of day and night, modern habits such as artificial light exposure or night shifts can push it out of sync, which has been linked to digestive problems and reduced concentration.

문제 8

In the days leading up to an endurance event, many athletes deliberately increase their carbohydrate intake while reducing training volume, a practice known as carbohydrate loading. (A) Because glycogen serves as the primary fuel source during prolonged, intense exercise, entering an event with fuller stores can delay the point of exhaustion that runners often call hitting the wall. (B) Sports nutritionists caution, however, that the timing and composition of meals matter as much as the total quantity of carbohydrate consumed. (C) The strategy is designed to maximize the amount of glycogen, the storage form of carbohydrate, packed into muscle tissue before competition begins.

문제 9

In other words, the body keeps a running total rather than resetting each day. Sleep debt refers to the cumulative gap between the amount of sleep a person needs and the amount they actually get. ( ① ) Unlike a financial debt, however, this deficit cannot simply be repaid with a single long weekend of rest. ( ② ) When someone loses two hours of sleep every night for a week, the body does not treat the shortage as fourteen separate small losses; instead, it accumulates the deficit, and the resulting impairment in attention and mood can resemble that of a person who has been awake for an entire night. ( ③ ) Researchers have found that even modest, chronic sleep restriction gradually impairs reaction time and decision-making, often without the affected person noticing the decline. ( ④ ) This is because subjective feelings of tiredness tend to plateau after a few days, even as objective performance keeps deteriorating. ( ⑤ ) Consequently, people frequently underestimate how much sleep debt they are carrying until a demanding task suddenly exposes the accumulated cost.

문제 10

Only in recent years have researchers begun to seriously question whether this long-standing fear was ever justified in the first place. Parents and coaches sometimes worry that heavy resistance training might damage the growth plates in a young athlete's bones, cartilage regions near the ends of long bones that are responsible for lengthening as a child develops. ( ① ) This concern kept strength training out of many youth programs for decades. ( ② ) However, extensive research over the past twenty years has found little evidence that properly supervised resistance training harms growth plates in healthy children. ( ③ ) The actual risk arises not from lifting weights itself but from poor technique, excessive load, and inadequate supervision, factors that can injure any part of a young athlete's body regardless of the activity involved. ( ④ ) Major pediatric and sports medicine organizations now generally agree that structured strength programs, when taught with correct form and appropriate weight, can safely improve bone density, coordination, and injury resistance in young athletes. ( ⑤ )
