When Mina was a freshman, she often spent her allowance within a few days. Her older cousin told her about the marshmallow experiment, a famous study in which children could eat one marshmallow ①immediately or wait for two. Researchers found that children who waited ②longer showed better academic performance and self-control years later. This ability to ③resist an immediate reward in favor of a larger future one is known as delayed gratification. Inspired by the study, Mina began saving half of her allowance each week instead of spending it all on snacks. At first, resisting small purchases felt surprisingly ④easy, especially when her friends were eating out. After three months, however, she had ⑤saved enough to buy a bicycle she had wanted for over a year.

When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers belonged only to a handful of government scientists. By the time he entered university, however, the space industry had changed ①dramatically, as private companies began launching satellites and building reusable rockets. Daniel studied aerospace engineering, drawn to the idea that space exploration was no longer ②limited to a few national agencies. During an internship, he helped design a small satellite intended to ③monitor crop health from orbit. He realized that the space industry now needed not only pilots and engineers but also data analysts, technicians, and even lawyers familiar with international space regulations. After graduation, Daniel joined a startup developing lunar landing equipment, a job that ④barely existed when he first imagined his future career. His story shows how commercial space ventures have ⑤closed doors that once seemed impossibly narrow.

As more schools shift toward digital textbooks and online assignments, a student without reliable internet access at home faces a disadvantage that has little to do with talent or effort. Some policymakers initially treated internet access as a convenience, comparable to cable television, rather than as infrastructure essential to modern life. That assumption is increasingly being reconsidered, particularly as _______________. Closing this divide will require more than simply distributing devices.

Sleep is not a single, uniform state but a cycle that alternates between two very different modes: REM (rapid eye movement) sleep and non-REM sleep. (A) REM sleep, by contrast, brings rapid eye movements and brain activity resembling wakefulness, and is believed to help consolidate memories and process emotions. (B) A healthy night cycles through both stages several times, and disrupting either one can leave a person feeling unrested despite a full night in bed. (C) During non-REM sleep, particularly its deepest stage, the brain waves slow dramatically and the body focuses on physical repair.

Last Saturday, Jimin visited the recycling center near her apartment with her science class. (A) She had expected the place to be dirty and unpleasant, but the center looked clean and well organized. A worker named Mr. Park guided the students through each area, explaining how bottles, cans, and paper were sorted. (B) He showed them a machine that crushed plastic bottles into small pieces before they were sent to factories. Jimin was surprised to learn that mixed trash, thrown into the wrong bin, often ruined an entire batch of recyclables. (C) For example, one greasy pizza box could contaminate a whole pile of clean paper. 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. She decided to sort her family's trash more carefully.

Good afternoon, everyone! Our town invites students to join a special tree-planting volunteer day next month. This event aims to restore a small forest damaged by last year's fire near the river. (A) Each participant will plant three young trees, guided by experienced forest rangers throughout the morning. For example, rangers will show volunteers how to dig proper holes without harming the tree roots. (B) Volunteers will meet at the community center at nine in the morning and travel together by bus. Please wear old clothes and shoes that you do not mind getting dirty during the activity. (C) In contrast, planting too shallowly often causes young trees to die within a few months. Therefore, careful instructions must be followed closely by every volunteer. Water and snacks, prepared by the town office, will be provided for free. Students interested in joining should register online before next Wednesday.

The eventual collapse of a speculative bubble often unfolds with surprising speed compared with the gradual climb that preceded it. (A) As prices begin to fall, investors who bought near the peak, motivated largely by fear of missing further gains, are often the first to sell, since they have the least conviction in the asset's underlying value. (B) Their selling triggers further price declines, which in turn prompt additional investors to sell out of a newly urgent fear of continued loss rather than a fear of missing out. (C) This reversal illustrates that the same herd psychology driving prices upward can just as easily reverse direction, converting collective optimism into collective panic within a remarkably short period.

Not all obstacles to renewable energy are technical or financial; some are psychological. (A) In contrast, switching demands research, upfront cost, and trust in unfamiliar technology, all of which can seem risky compared with doing nothing. For example, a neighborhood association might repeatedly postpone a vote on shared solar panels, not because the plan is flawed, but because members are reluctant to leave their routine. Therefore, boosting renewable adoption may depend less on proving its advantages and more on designing programs that make the first step feel easy. (B) Behavioral economists use the term status quo bias to describe a tendency to prefer the present situation over a new alternative, even when the alternative would bring greater benefits. (C) This bias helps explain why many households hesitate to switch to renewable energy, such as installing solar panels on their roofs. Although solar panels can lower electricity bills over time, homeowners often stick with their current power source because it feels safe and requires no immediate effort.

Good morning, residents of Green Apartment! We would like to introduce a simple way to protect our environment, since used batteries contain harmful chemicals that should never be thrown away with regular trash. (A) If these chemicals leak into the soil, they can pollute water and harm plants, so our building has installed a special collection box for used batteries near the main entrance. (B) We appreciate your effort to keep our neighborhood clean and safe, and thank you for your cooperation and kindness. (C) Please place your old batteries inside this box instead of the trash can, since the box, which is emptied every month, is easy for anyone to use.

주어진 문장: That plan, however, took an unexpected turn during his final year of university. Jiho had always assumed he would join a large corporation after graduation, just as his parents expected. ( ① ) He joined a small student team building an app that connected local farmers directly with restaurants. ( ② ) What started as a class project gradually turned into something more serious, as several restaurants began placing regular orders through their prototype. ( ③ ) Jiho and his teammates decided to delay job applications and instead spend a year developing the idea, despite warnings from relatives who considered the plan too risky. ( ④ ) They worked from a cramped apartment, surviving on limited savings while learning skills ranging from coding to negotiating with suppliers. ( ⑤ ) After nearly failing twice, the team secured a small investment that allowed them to hire their first employee.
