문제 1

When individuals face uncertainty about how to behave, they frequently look to the actions of others for guidance, ①assuming that a behavior adopted by many people is more likely to be correct or appropriate than one adopted by few, a tendency known as social proof. This reliance on collective behavior can be remarkably efficient, since it allows individuals ②to benefit from the accumulated judgment of a crowd without having to gather and evaluate every relevant fact themselves. However, social proof can also lead entire groups astray when the initial signal that ③trigger imitation is itself unreliable or coincidental. A restaurant that happens to attract a long line early in the evening may continue attracting customers throughout the night simply because passersby ④interpret the queue as evidence of superior quality. Financial markets exhibit an analogous pattern: investors who observe others buying a particular asset often join the buying themselves, ⑤reasoning that so many participants cannot all be mistaken.

문제 2

Marketers have long recognized that perceived scarcity, the sense that a product or opportunity ①are available only in limited quantity or for a limited time, can dramatically increase its desirability, even when the item's intrinsic qualities remain entirely unchanged. This phenomenon, known as the scarcity effect, operates on a simple psychological principle: when something appears difficult to obtain, people tend ②to infer that it must be valuable, since truly worthless items rarely generate genuine competition for possession. A retailer who labels a product as "limited edition" or displays a countdown timer beside a discounted offer exploits this inference, ③prompting customers to make hurried purchase decisions they might otherwise postpone or reconsider. Experimental studies confirm that identical products ④are rated as more desirable and often command higher prices when framed as scarce than when the same products are presented as widely and continuously available. The effect intensifies further when scarcity is attributed to high demand rather than to limited supply alone, since competition from other buyers ⑤introduces an additional layer of urgency absent from mere supply constraints.

문제 3

Setting a career plan early in high school ①offers several important benefits. First, having a general direction helps students ②choose subjects and activities that support their goals. Second, a plan gives students a sense of purpose, ③which can make schoolwork feel more meaningful. However, an effective career plan should remain flexible, since interests and circumstances often ④changes during the teenage years. Career counselors therefore recommend ⑤reviewing a plan every few months and adjusting it based on new experiences.

문제 4

Psychologists have long studied a mechanism called the variable reward schedule, in which rewards ①arrive unpredictably rather than after every single action. Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. When someone posts a photo, they cannot predict exactly when likes will appear, nor ②how many they will eventually receive. This uncertainty triggers a small burst of dopamine each time the phone ③is checked, regardless of whether the result is disappointing or thrilling. Consequently, users often refresh their feeds compulsively, ④hoping the next check will finally bring a satisfying reward. What makes this troubling is that technology companies deliberately designed notification systems using insights borrowed from gambling research, rather than ⑤stumble upon them by accident.

문제 5

Long before humans learned to drill for oil, microorganisms had already ①mastered the art of converting sunlight and carbon dioxide into stored chemical energy. Modern biofuel research borrows this ability, cultivating algae or engineered bacteria in large tanks where they can be coaxed into producing oils and sugars that can be ②refined into fuel usable in existing engines. Unlike crops grown for corn-based ethanol, which ③compete directly with food production for arable land, many algae strains can thrive in shallow ponds, wastewater, or even coastal seawater unsuitable for conventional agriculture. Engineers have also learned to tinker with the metabolic pathways of these organisms, boosting oil yield far beyond what any wild strain would naturally produce on its own. Despite this progress, producing biofuel at a cost competitive with fossil fuel remains ④difficult, since harvesting and processing the organisms ⑤conserves a substantial share of the energy the fuel itself will eventually provide.

문제 6

Facial recognition software has moved rapidly from airport security lines into shopping malls, schools, and even private apartment buildings. (A) Independent studies, however, have repeatedly found that many commercial systems perform less accurately on women and people with darker skin tones. (B) Proponents note that the technology can unlock doors, catch shoplifters, and speed up identity checks far faster than any human guard could manage. (C) Several cities have already reported cases in which an innocent person was detained based on a flawed match.

문제 7

Researchers have long debated why people often behave so differently once they log onto the internet. (A) On the other hand, this same freedom can turn destructive when users hide behind anonymity to attack others without fear of being identified. (B) One explanation lies in the reduced sense of accountability that anonymity and physical distance create, allowing hidden emotions to surface more easily. (C) For instance, someone who feels lonely might open up honestly in an online forum, sharing feelings they would never mention to coworkers.

문제 8

It is also important to wear bright or reflective clothing so that drivers can see you clearly. Riding a bicycle is a great way to stay active during summer vacation, but safety should always come first. ( ① ) Before you ride, check that your tires are properly inflated and your brakes are working well. ( ② ) Wearing a helmet is essential, since it can prevent serious head injuries in an accident. ( ③ ) Riders should always follow traffic signals and ride in the same direction as traffic, never against it. ( ④ ) In addition, keep both hands on the handlebars and avoid using your phone while riding. ( ⑤ ) Carrying a water bottle is wise, since dehydration can cause dizziness and affect your balance.

문제 9

Instead, these trainers help workers use AI tools wisely, without becoming fully dependent on them. As artificial intelligence becomes part of everyday life, entirely new job titles are appearing in the workplace. ( ① ) Prompt engineers, for instance, design effective instructions that help AI programs produce accurate and useful results. ( ② ) AI ethics officers examine whether a company's technology treats users fairly and avoids harmful bias. ( ③ ) Meanwhile, human-AI collaboration trainers do not simply teach employees to use every new AI feature available. ( ④ ) These jobs did not exist even ten years ago, yet they are growing quickly across many industries. ( ⑤ ) This suggests that success in an AI-driven future will depend more on uniquely human skills.

문제 10

주어진 문장: Without such improvements, even the most generous rewards program cannot compensate for a disappointing product. Building brand loyalty has traditionally been considered one of the most valuable goals in marketing, since loyal customers tend to spend more and recommend products to others. ( ① ) Companies invest significant resources in loyalty programs, offering points, discounts, and exclusive access to encourage repeat purchases. ( ② ) However, some critics argue that these programs manipulate consumers into staying with a brand out of habit rather than genuine satisfaction. ( ③ ) Genuine loyalty, they contend, should be earned through consistent quality and honest treatment of customers. ( ④ ) Furthermore, excessive focus on retaining existing customers can cause companies to neglect innovation, since they assume loyal buyers will continue purchasing regardless of improvements. ( ⑤ ) As markets become more competitive, relying solely on loyalty programs without addressing underlying product quality may ultimately backfire.
