As solar and wind power expand ①rapidly across national grids, engineers face a challenge that receives far less public attention than the construction of the generating facilities themselves. Unlike conventional power plants, which can adjust their output to match demand at almost any moment, solar panels and wind turbines generate electricity only when sunlight or wind is available, producing supply that fluctuates ②rarely. One proposed solution involves large-scale battery storage systems, which absorb ③surplus electricity generated during periods of high output and release it later when generation declines. Another approach relies on expanding transmission networks across wider regions, so that electricity generated in a sunny area can be redirected to places experiencing a ④shortfall. Without such investment, integrating renewable energy could ⑤paradoxically undermine the very reliability that modern electricity grids are expected to provide.

The science club at Hanul High School is running a project called "Grow Light." It tests how different colors of light affect plant growth. Each week, members place ①identical bean sprouts under red, blue, and white light and record their height. At first, many students expected the white light to produce the tallest plants. However, the results showed that plants under red light grew ②noticeably faster than the others. The club's advisor explained this by comparing light to food. Just as people need certain nutrients to grow strong, plants absorb certain colors of light more ③efficiently than others. To make the data ④reliable, students repeat each trial three times and calculate the average. They also keep a shared notebook, recording sunlight, watering time, and temperature. Next month, the club plans to ⑤hide these findings at the school science fair.

Generative AI systems learn to write, draw, and compose by studying ①enormous collections of existing human work, much of which was created without the artists' knowledge or consent. Supporters of the technology argue that this process resembles how a human student learns by studying the masters, ②absorbing style and technique rather than copying specific pieces. Critics respond that the comparison ③holds up perfectly at scale, since a single AI model can absorb millions of works in days. Courts around the world are now being asked to decide whether training an algorithm on copyrighted material counts as fair use or as ④infringement. Until clearer rules emerge, artists, developers, and publishers remain locked in a legal ⑤gray zone that satisfies almost no one.

The city government has launched a summer energy-saving campaign to ①reduce electricity use during the hottest months. Using fans together with air conditioners cools rooms more efficiently while using ②more power. To prevent blackouts, residents are asked to set air conditioners no lower than twenty-six degrees Celsius, which helps save ③energy. Businesses are asked to dim unnecessary outdoor signs after ten at night. Families who reduce their electricity use by more than ten percent will receive a ④discount on their next bill, which is a nice ⑤reward for their effort.

Many households save far less for retirement than conventional financial advice would recommend. Some economists have proposed a savings program in which employees commit today to allocating a portion of their future salary increases toward retirement savings, rather than being asked to reduce their current take-home pay immediately. Field trials of such programs have reported substantial increases in average savings rates. This approach demonstrates that savings policy grounded in realistic assumptions about human psychology can prove considerably more ___________ than policy grounded in the assumption that individuals will always act in strict accordance with their own long-term rational interests.

Every spring, the art club at Sejong High School creates one large mural together instead of individual paintings. The process begins with a session where members suggest themes and vote on their favorite idea. Once a theme is chosen, the club divides into small teams, each responsible for one section of the wall. One team sketches the outline while another mixes colors to match the design. Communication becomes essential at this stage, since each section must connect smoothly with the ones beside it. If one team paints too dark a shade, the whole picture can look unbalanced. Therefore, members regularly step back to compare their section with the rest of the mural. After several weekends, the teams combine their sections into a single image. The finished mural is displayed near the entrance, reminding everyone _______________________.

Choosing the next book is not always simple for the reading club. (A) After the short list is posted, members read a few pages of each book before voting. (B) First, anyone can suggest a title they have recently enjoyed or heard about. (C) In the end, the book with the most votes becomes the club's next read.

Jimin joined the school band club in March, but she had never performed before an audience. The club's first concert was only two weeks away, and everyone felt nervous. (A) Instead of laughing at her mistakes, however, the other members waited patiently and played the section again with her. The drummer, Suho, suggested that she focus on just one part at a time, and slowly her fingers grew more confident. (B) As a result, the club practiced until the melody sounded smooth the night before the concert. When Jimin finally walked onto the stage, she thought of her friends' patience instead of her fear, and the audience's warm applause proved that their support had made the difference. (C) During practice, her hands shook whenever the song reached the chorus, and she kept missing the same chord.

Many students confuse the student council with school clubs. In fact, the two groups serve very different purposes. (A) Therefore, joining the council usually requires an election, whereas joining a club simply requires genuine interest. Some students eventually do both, using the council to build leadership skills and a club to develop a personal passion. (B) The student council is an official body that represents the whole school. It manages shared issues such as rules, events, and communication with teachers. For example, council members often organize the school festival and collect opinions from each class before making decisions. (C) A club, in contrast, is a small group formed around one shared interest, such as music or art. While the council must consider the needs of every student, a club can focus narrowly on what its own members enjoy.

If such a divide hardens, competitive advantages in school, sports, and the workplace could come to depend less on effort than on access to capital. Beyond restoring lost function, engineers are now exploring implants and prosthetics designed to give healthy people abilities beyond ordinary human limits. ( ① ) Supporters frame this as simply the next step in a long history of human enhancement, no different in principle from eyeglasses or vaccines. ( ② ) Critics counter that earlier enhancements were broadly available to anyone regardless of wealth. ( ③ ) Cutting-edge neural and physical implants, by contrast, are likely to remain expensive for decades, potentially splitting society into those who can afford enhancement and those who cannot. ( ④ ) What began as a medical tool for restoring what was lost, in other words, may end up redefining the baseline of what counts as an ordinary human being. ( ⑤ )
