Anthropologist Robin Dunbar ①proposed a concept now known as Dunbar's number, suggesting that human beings can only maintain about one hundred fifty stable social relationships at any given time. This limit, he argued, comes from the size of the human brain, ②which restricts how many meaningful connections a person can cognitively manage. In contrast, many social media users today have hundreds or even thousands of online friends and followers, a number far ③exceeding what Dunbar's research predicts. However, having numerous digital contacts does not necessarily mean that all of these relationships ④are close or emotionally supportive. Most users, when asked, admit that they interact regularly with only a small fraction of their total followers, while the rest remain ⑤largely unnoticing.

A rational approach to decision-making dictates that only future costs and benefits should influence a choice, since resources already spent ①cannot be recovered regardless of what is decided next. In practice, however, people routinely allow such irrecoverable expenditures, known as sunk costs, ②to shape their subsequent decisions, a pattern referred to as the sunk cost fallacy. A moviegoer who finds a film thoroughly disappointing after the first thirty minutes will often remain in the theater until the credits roll, ③reasoning that leaving early would somehow waste the money already spent on the ticket. Organizations exhibit the same fallacy on a larger scale: a company that ④have invested heavily in a failing project frequently continues funding it, arguing that abandoning the project now would render the prior investment meaningless. Yet continuing to invest in a venture destined to fail merely adds new losses to old ones, ⑤compounding the very waste the decision-makers hoped to avoid.

I made sure to drink ①cold water instead of only cold drinks, and I began carrying a light jacket to wear indoors when the room felt too ②cold. I also started stretching and walking around every hour instead of sitting still all day, which helped me feel more ③energetic. Within a few days, my headaches ④disappeared, and I felt much more ⑤healthy.

When engineers design the software that controls a self-driving car, they inevitably face a question that philosophers have debated for ①decades. If a crash becomes unavoidable, should the vehicle protect its own passenger at all costs, or should it be programmed to ②minimize total harm, even if that means steering toward the person inside? Surveys reveal an uncomfortable ③contradiction: most people say a car should be programmed to save the greater number of lives, yet the same people admit they would never buy a vehicle designed to sacrifice its own owner. This gap between the ideal and the personal choice suggests that ethical programming cannot be settled by public opinion alone. Manufacturers, regulators, and philosophers must instead agree on ④transparent rules before autonomous vehicles are ⑤forbidden to make such decisions on the road.

Last summer, I worked part-time at a small coffee shop near my house. I learned how to stay calm during busy hours and communicate clearly with customers. One day, a customer complained loudly about a mistake in her order. Instead of arguing, I apologized and quickly made a new drink for her. She left with a smile, and my manager praised my patience afterward. Through small moments like this, I began to understand ___________. The part-time job did not pay much, but the lessons it gave me were worth far more than the money.

Last January, Minji decided that she would run three kilometers every morning before school, but after a few cold mornings, she began oversleeping and soon stopped running altogether. By February, she felt disappointed and believed she simply lacked willpower. One evening, her older brother asked her why the plan had failed, and together they looked closely at her daily schedule. They realized that running before sunrise in freezing weather had been too difficult to maintain. So Minji changed her plan and decided to run after school instead, when the weather was warmer and she had more energy. This experience taught her that ___________.

On a summer evening, downtown streets often feel noticeably hotter than nearby parks or suburban neighborhoods, even after the sun has set. This phenomenon, known as the urban heat island effect, occurs when _______________. Unlike soil or vegetation, which absorb and release heat gradually, these man-made surfaces absorb sunlight during the day and slowly radiate it back at night, preventing temperatures from cooling. Tall buildings packed closely together also block wind, trapping warm air within narrow streets. In contrast, areas with abundant trees and open water naturally stay cooler, since plants release moisture that helps lower surrounding temperatures. To reduce this effect, many cities have begun installing rooftop gardens and expanding public parks, hoping that additional greenery will absorb less heat than pavement does.

My grandmother keeps a wooden cabinet filled with tiny furniture, each piece no larger than a fingernail, that she has been building for over a decade as a miniature hobby. (A) Talking with her while she worked, though, I learned that the real challenge lies in imagining an entire, believable world at a scale the eye can barely process. (B) She once spent three weekends carving a single tiny bookshelf, only to leave two of its shelves deliberately empty, explaining that a completely full room would look staged rather than lived-in. (C) When I first saw the cabinet, I assumed the appeal was simply how impressively small and precise the pieces looked.

주어진 문장: This single mistake meant that workers had to sort the entire pile again by hand. Last Saturday, Jimin visited the recycling center near her apartment with her science class. ① She had expected the place to be dirty and unpleasant, but the center looked clean and well organized. ② A worker named Mr. Park guided the students through each area, explaining how bottles, cans, and paper were sorted. He showed them a machine that crushed plastic bottles into small pieces before they were sent to factories. ③ Jimin was surprised to learn that mixed trash, thrown into the wrong bin, often ruined an entire batch of recyclables. For example, one greasy pizza box could contaminate a whole pile of clean paper. ④ However, when items were sorted correctly, they could be reused many times, almost like ingredients in a favorite recipe. Walking home, Jimin realized that her small effort at home truly mattered. ⑤ She decided to sort her family's trash more carefully.

Journalists now face the burden of verifying footage that once would have been accepted as self-evident proof. A few years ago, spotting a manipulated video required a trained eye and specialized software. ( ① ) Today, freely available applications allow almost anyone to swap a face or fabricate a voice convincingly enough to fool casual viewers within minutes. ( ② ) This shift has quietly undermined one of the oldest assumptions in human communication: that seeing and hearing something is a reasonably reliable way to confirm it happened. ( ③ ) Perhaps more troubling than any single fake video is the broader effect on public trust, sometimes called the liar's dividend, in which genuine footage can be dismissed as fabricated simply because deepfakes exist. ( ④ ) In this environment, the mere possibility of manipulation can be almost as damaging as manipulation itself. ( ⑤ )
