When Mina was a freshman, she often ①spent her allowance within a few days. Her older cousin told her about the marshmallow experiment, a famous study ②in which children could eat one marshmallow immediately or wait for two. Researchers found that children who waited longer ③shown better academic performance and self-control years later. Inspired by the study, Mina began ④saving half of her allowance each week instead of spending it all on snacks. After three months, however, she had saved enough to buy a bicycle she had ⑤wanted for over a year.

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 ① during a brief disruption such as an eye movement or a momentary obstruction. In a now-famous demonstration, researchers showed ② participants two versions of a photograph in alternation, separated by a short blank screen, and asked them to identify what had changed. Even when an entire building disappeared or a person's clothing shifted color, many viewers stared at the picture without detecting ③ anything unusual. 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. Whatever falls outside that narrow spotlight represents ④ only sparsely, if at all, leaving it vulnerable to being overwritten without notice. Consequently, change blindness demonstrates that our impression of a rich, complete visual world is, to a surprising extent, an illusion constructed ⑤ by the mind, not a faithful record of external reality.

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.

Among the many tools available to those who design choice environments, few are as quietly ①powerful as the default option, the alternative that takes effect automatically unless a person actively selects something else. Because changing a default requires ②deliberate effort, many individuals simply accept whatever arrangement has been preselected for them, regardless of whether that arrangement actually serves their interests best. Countries that automatically enroll citizens in organ donation programs, requiring an explicit request to opt out, consistently report far ③lower donor registration rates than countries that require citizens to actively opt in. Employers who automatically enroll new hires in retirement savings plans likewise see participation rates climb dramatically compared with employers who leave enrollment entirely voluntary. What makes default options so influential is not merely convenience; a default also functions as an implicit signal about what is considered ④normal or recommended, subtly shaping perceptions even among individuals who believe themselves to be deciding ⑤independently.

Anthropologist Robin Dunbar proposed 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, which 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 exceeding what Dunbar's research predicts. However, having numerous digital contacts does not necessarily mean that all of these relationships are 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 largely unnoticed. Therefore, Dunbar's number reminds us that ___________.

Have you ever noticed your mood shifting after scrolling through a friend's gloomy post online? This phenomenon, known as emotional contagion, refers to the tendency of one person's feelings to spread to others nearby, almost like a cold passing between classmates. However, researchers have discovered that emotional contagion also occurs online, where only text or images are exchanged, without any physical presence at all. For instance, when someone posts a negative comment beneath a cheerful photo, the comments that follow often turn noticeably more negative in tone. In contrast, a single kind comment can shift an entire thread toward positivity within minutes. This suggests that emotions online spread through carefully chosen words alone. Consequently, many experts now argue that ___________.

Every day, people throw away piles of used paper without thinking about where it goes. However, most of that paper does not have to end up in a landfill. (A) First, workers collect old newspapers, boxes, and notebooks left in recycling bins. These papers are then soaked in water and turned into soft, mushy pulp. You can think of this process like breaking a cookie back into flour and water. (B) For example, ink and small pieces of plastic are removed from the pulp during this stage. The clean pulp is pressed into thin sheets and dried in large machines. Therefore, a wrinkled old newspaper can be reborn as clean white paper. In contrast to throwing paper away, recycling it saves trees and reduces waste. (C) Instead, it can travel to a recycling factory and become brand new paper again.

Irving Janis, a psychologist, used the term groupthink to describe how close-knit groups sometimes make poor decisions together. (A) Trusting this shared confidence, the group moved forward without pausing to consider whether the shortcut might cause problems later. (B) In one online study group, for example, a suggestion to skip an important step was accepted almost instantly, with no one voicing concerns. (C) Only after their project was criticized for missing key information did the members recognize how strongly the group's harmony had silenced doubt.

주어진 문장: These various booths give every member a chance to show what they have practiced throughout the year. Every October, Greenfield High School holds a festival that gives every club a chance to shine. ① This year's festival will take place on October 15th, running from nine in the morning until four in the afternoon. ② Clubs that want to run a booth must apply to the student council by October 1st, since space in the gym is limited. ③ The science club will present simple experiments that are both safe and exciting to watch. The art club, meanwhile, will display paintings that members have created throughout the semester. ④ The cooking club plans to sell snacks prepared by its own members, and all the profits will be donated to a local shelter. ⑤ Because many visitors are expected, teachers will supervise each booth carefully to keep students safe. Anyone curious about club life is warmly encouraged to visit and enjoy the festival.

주어진 문장: Even during lunchtime, however, a few members quietly check the equipment for the next broadcast. Most students only see the final result, a few smooth minutes each morning. Behind that short program, however, broadcasting club members follow a busy daily routine. ① Members arrive at school thirty minutes earlier than other students to prepare the studio. They check the microphones, the cameras, and the lighting before anyone else arrives. ② Meanwhile, the script team finalizes the news script that was written the night before. Once everything is ready, the anchors practice their lines one last time. ③ At exactly eight o'clock, the red light turns on, and the live broadcast begins. During class hours, however, most members return to their regular classroom lessons like everyone else. ④ After school, the club meets again to review that morning's recording and discuss any mistakes. ⑤ Through this daily routine, members slowly learn skills such as teamwork and quick thinking under pressure.
