문제 1

A plastic bag that fully decomposes within months rather than lingering for centuries sounds almost too convenient to be real, yet certain bioplastics on the market ①do exactly that under the right conditions. Unlike conventional plastic, derived almost entirely from petroleum, many bioplastics are ②synthesized from renewable feedstocks such as corn starch or sugarcane, sometimes with the help of bacteria engineered to produce plastic-like polymers as a byproduct of their metabolism. Not every bioplastic biodegrades quickly, however, and some marketed as eco-friendly break down only in industrial composting facilities ③that reach conditions rarely found in a backyard compost heap or the open ocean. Critics point out that growing crops for bioplastic production can compete with food crops for farmland and water, ④complicating the assumption that a biological origin automatically makes a material more sustainable. Researchers are now exploring bioplastics made from agricultural waste and algae instead of dedicated crops, hoping to ⑤sidestepping this competition for land while preserving the benefits that first made bioplastics appealing.

문제 2

Many students wonder why club activities ①matter so much for their school life record, a document that summarizes what a student did during each semester. Whenever students take part in a club, their teacher writes a short note describing what role they played and how they grew. For example, a student who organized a club exhibition might be described as someone who showed ②strong leadership and creativity. These notes are not simply a list of activities; they explain the process behind each achievement. Therefore, admissions officers at universities read the record carefully to understand a student's ③genuine interests, not just their grades. In contrast, a club membership with no real participation rarely leaves a ④meaningful impression. This is why teachers encourage students to take a ⑤passive role rather than joining a club only for its name.

문제 3

Turning off lights when you leave a room seems like a ①huge action, but it saves more energy than most people expect. Both actions seem ②harmless in the moment, but they add up to a ③serious waste over time. However, when an entire school forms this habit together, the total amount of saved energy becomes ④significant. Therefore, this small daily habit can create a surprisingly ⑤large positive effect for the whole planet.

문제 4

During exam season last year, our school counselor introduced a weekly drop-in session where students could paint freely for thirty minutes without any instructions or grading. I attended mostly out of ①curiosity, expecting a relaxing but ultimately pointless activity, since I have never considered myself artistically talented. To my surprise, filling a blank page with color, without worrying whether the result looked good, left me noticeably ②calmer than scrolling through my phone during the same amount of free time. The counselor explained that art therapy does not aim to produce impressive paintings; it simply gives people a way to express feelings that are difficult to put into words, especially ③frustration or anxiety that builds up silently during a stressful week. Several classmates who initially came only to avoid studying kept ④returning on their own afterward. None of us left with a masterpiece, but many of us left the room feeling noticeably ⑤heavier than when we had walked in.

문제 5

Classical economic theory assumes that consumers evaluate every price change in the same rational way, weighing marginal benefit against marginal cost regardless of the absolute numbers involved. (A) In a well-known laboratory experiment, participants chose between two chocolates, one of higher quality priced at a small fee and one of lower quality offered for free. When both prices were merely reduced by the same amount, most participants still preferred the higher-quality option. Yet once the cheaper chocolate's price was lowered to zero, the majority abruptly switched their preference, even though the price gap between the two options had not actually changed. (B) Researchers explain this reversal by noting that a free item carries no perceived risk of loss, which makes it feel disproportionately attractive compared with any option that still requires payment, however small. (C) Behavioral economists, however, have discovered a striking exception: the moment a price drops to exactly zero, people's judgment shifts in a way that ordinary discounting cannot explain.

문제 6

A weekend camping trip promises fresh air and a break from screens, but the same wilderness that makes camping appealing also removes many of the safety nets people rely on without noticing, such as nearby hospitals or cell phone signal. (A) Experienced campers also stress the importance of checking a weather forecast before leaving, since a clear evening sky offers no guarantee against a sudden storm later that night. (B) One of the most overlooked risks is setting up a tent too close to a campfire, since a sudden gust of wind can carry a spark onto dry fabric faster than anyone expects. (C) Food storage is another area where casual habits create danger: leaving snacks inside a tent, rather than in a sealed container away from the sleeping area, can attract wildlife looking for food.

문제 7

For my birthday, my older sister took me to a small pottery studio where visitors can shape their own bowl or cup on a spinning wheel. (A) My first attempt collapsed into a shapeless lump within seconds, because I had not realized how much steady, centered pressure the clay actually requires before it can be shaped at all. (B) After nearly a dozen failed attempts, I finally produced a lopsided but recognizable cup, and the small imperfection along its rim somehow made me prouder of it than a perfectly smooth, machine-made mug ever could have. (C) I expected the wheel to do most of the difficult work automatically, since it was already spinning quickly by the time I sat down.

문제 8

주어진 문장: Yet many people write down their goals at the beginning of the year and never check how far they have come. Setting a goal is only the first step; keeping track of progress is just as important. ( ① ) Without regular records, it becomes easy to lose motivation or forget the original purpose of a goal. ( ② ) Keeping a simple log, such as a weekly checklist or a short journal entry, lets a person see clear evidence of improvement over time. ( ③ ) For instance, someone learning guitar might record which songs they practiced each week, and looking back later reveals growth that felt invisible day to day. ( ④ ) Tracking progress also helps identify problems early, since a person can notice when effort stops producing results and adjust the plan before too much time is wasted. ( ⑤ )

문제 9

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.

문제 10

주어진 문장: Fortunately, this cycle is not impossible to reverse. An echo chamber refers to an online environment where people are mainly exposed to opinions that already match their own beliefs. ( ① ) This phenomenon occurs because social media algorithms tend to recommend content similar to what users have previously liked or shared, gradually narrowing the range of perspectives they encounter. ( ② ) As a result, individuals inside an echo chamber rarely engage with viewpoints that challenge their existing assumptions, which allows their original beliefs to grow increasingly extreme over time. ( ③ ) For example, someone who frequently reads articles supporting one political party may begin to see the opposing party as entirely unreasonable, having never seriously considered its arguments. ( ④ ) Political polarization, a significant issue in many countries today, is often linked to this pattern of selective exposure. ( ⑤ ) Breaking out of an echo chamber requires deliberately seeking information from diverse sources, even when those sources present uncomfortable or unfamiliar ideas.
