문제 1

When people consistently sleep too little, the body's hormonal balance shifts in ways that can quietly ①encourage weight gain. Two hormones in particular play opposing roles in regulating appetite: leptin signals fullness to the brain, while ghrelin ②stimulate the sensation of hunger. Studies show that sleep deprivation lowers leptin levels while raising ghrelin levels, so a tired body ends up ③feeling hungrier than it actually needs to be, even after a normal-sized meal. At the same time, insufficient sleep interferes with how efficiently the body processes glucose, making cells less responsive to insulin and ④leaving more sugar circulating in the bloodstream than usual. Over months or years, this combination of increased appetite and reduced insulin sensitivity can contribute to steady weight gain and ⑤raise the risk of developing type 2 diabetes.

문제 2

Our school's volunteer club, Helping Hands, ①tries to make small acts of kindness feel natural. Each month, students visit a nearby nursing home and spend an afternoon ②talked with elderly residents. For example, they read newspapers aloud or just listen to old stories from the residents. In addition, members collect used books and toys from classmates and ③donate them to a community center downtown. Some students feel nervous before their first visit, unsure of what ④to say to strangers. However, most discover that a warm smile works better than perfect words. Therefore, the club's real goal is not just finishing hours for a report card. Instead, it teaches members that ⑤caring for others grows into a lasting habit, like watering a plant daily. By the end of the year, many students say the club changed how they see their community.

문제 3

Choosing a college major is one of the biggest ①decisions many students face after high school. Some students assume that their major will completely determine their future career, but this is not always true. What matters more than the major itself is the set of skills a student develops, such as critical thinking, writing, and problem solving. These abilities can be applied to ②a single career only. However, choosing a major that genuinely interests a student still matters, because motivation makes learning ③easier and more effective. Therefore, students should choose a major based on ④curiosity and personal growth, not only on which job it seems to ⑤guarantee.

문제 4

Walking down a crowded street while staring at a phone screen has become such a common sight that it barely draws attention anymore, even though the habit turns a pedestrian into one of the ①most alert people on the sidewalk. Researchers who study attention describe this as a kind of tunnel vision: a person absorbed in a text message or a video processes only a ②narrow slice of the surrounding environment, filtering out approaching cars, uneven pavement, and other pedestrians almost entirely. What makes this danger especially difficult to address is that pedestrians ③rarely recognize the risk in the moment; unlike distracted driving, which is widely ④condemned, glancing at a phone while crossing the street still feels like a ⑤harmless habit to most people who do it every day.

문제 5

Consider a student who ①genuinely intends to study for tomorrow's exam yet, when the evening actually arrives, chooses to watch another episode of a favorite show instead, promising herself she will surely study harder next week. This pattern, in which the pull of an immediate pleasure ②overwhelms the value of a distant benefit, appears again and again across ordinary life, from postponed exercise to delayed savings. People do not necessarily fail to understand that the future reward matters more; rather, whatever happens right now simply feels disproportionately more urgent and vivid than anything scheduled for later. Behavioral economists note that this preference ③weakens considerably once both options are pushed into the future, which is why planning a diet starting next month feels ④impossible compared with skipping dessert tonight. Such inconsistency helps explain why gym memberships go unused and retirement accounts remain ⑤underfunded, despite people's stated intentions.

문제 6

In a classic experiment inspired by Keynes's beauty contest analogy, participants choose a number between zero and one hundred, and the winner is whoever selects the number closest to two-thirds of the average of all guesses submitted. (A) In practice, however, actual guesses rarely converge on zero; most participants stop reasoning after a round or two of imagining what others might guess, producing average guesses that cluster between twenty and thirty-five. (B) A perfectly rational player, assuming every other participant reasons with unlimited depth, would conclude the equilibrium number is zero, since reasoning about others' reasoning collapses the average toward that single point. (C) This gap between theoretical equilibrium and observed behavior reveals that human reasoning is bounded, and economists use this simple game as a diagnostic tool for measuring the depth of that reasoning.

문제 7

Many students confuse the student council with school clubs. In fact, the two groups serve very different purposes. (A) Therefore, joining the council usually requires an election, whereas joining a club simply requires genuine interest. Some students eventually do both, using the council to build leadership skills and a club to develop a personal passion. (B) The student council is an official body that represents the whole school. It manages shared issues such as rules, events, and communication with teachers. For example, council members often organize the school festival and collect opinions from each class before making decisions. (C) A club, in contrast, is a small group formed around one shared interest, such as music or art. While the council must consider the needs of every student, a club can focus narrowly on what its own members enjoy.

문제 8

주어진 문장: The two images were otherwise identical in every respect, differing only in the single altered detail. Change blindness refers to a striking limitation of human perception in which observers fail to notice substantial alterations to a visual scene, provided the change occurs during a brief disruption such as an eye movement or a momentary obstruction. ( ① ) In a now-famous demonstration, researchers showed participants two versions of a photograph in alternation, separated by a short blank screen, and asked them to identify what had changed. ( ② ) Even when an entire building disappeared or a person's clothing shifted color, many viewers stared at the picture without detecting anything unusual. ( ③ ) This phenomenon occurs because visual attention, rather than passively recording every detail like a camera, actively selects only a narrow subset of information for processing at any given moment. ( ④ ) Whatever falls outside that narrow spotlight is represented only sparsely, if at all, leaving it vulnerable to being overwritten without notice. ( ⑤ ) Consequently, change blindness demonstrates that our impression of a rich, complete visual world is, to a surprising extent, an illusion constructed by the mind, not a faithful record of external reality.

문제 9

주어진 문장: This small effort makes the recycling process faster and more efficient for everyone. Dear residents, this notice explains how to use our apartment recycling area correctly. The recycling area, located behind the main entrance, is open every day from six to ten in the evening. ① First, sort your items into the labeled sections for paper, plastic, glass, and cans before dropping them off. ② Boxes should be flattened, and bottles should be emptied, because dirty items are hard to recycle. However, please do not leave large furniture or electronics in this area at any time. ③ Instead, contact the management office to arrange a separate pickup for those bulky items. For example, broken chairs and old refrigerators require a special sticker before collection. ④ In contrast to ordinary trash, recyclable materials must never be mixed together in one bag. ⑤ Following these simple rules keeps our shared space tidy for every family.

문제 10

This is because waiting for paramedics to arrive can cost a student the few minutes that make the difference between recovery and tragedy. A food allergy can turn an ordinary snack shared between classmates into a medical emergency within minutes, which is why schools now take ingredient labels more seriously than they once did. ( ① ) For someone with a severe allergy, even a trace amount of the wrong ingredient, transferred by a shared spoon or an unwashed hand, can trigger a reaction that closes the airway and becomes life-threatening if untreated. ( ② ) Friends of allergic students sometimes assume that a small bite would not cause serious harm, not realizing that the amount needed to trigger anaphylaxis can be smaller than a crumb. ( ③ ) Recognizing the early signs, such as swelling around the lips, hives, or sudden difficulty breathing, allows classmates and teachers to act before the reaction becomes severe. ( ④ ) Many schools now train staff to use an epinephrine auto-injector, a device that can reverse a dangerous reaction within seconds. ( ⑤ )
