The science club at Hanul High School is running a project ①called "Grow Light." It tests how different colors of light affect plant growth. Each week, members place identical bean sprouts under red, blue, and white light and ②record their height. At first, many students expected the white light ③to produce the tallest plants. However, the results showed that plants under red light grew noticeably ④fast 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 efficiently than others. To make the data reliable, students repeat each trial three times and calculate the average. They also keep a shared notebook, ⑤recording sunlight, watering time, and temperature.

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. Members arrive at school thirty minutes earlier than other students ① preparing the studio. They check the microphones, the cameras, and the lighting before anyone else ② arrives. Meanwhile, the script team finalizes the news script that was ③ written the night before. Once everything is ready, the anchors ④ practice their lines one last time. 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. After school, the club meets again to review that morning's recording and ⑤ discuss any mistakes. Through this daily routine, members slowly learn skills such as teamwork and quick thinking under pressure.

Marketers have long recognized that perceived scarcity, the sense that a product or opportunity is available only in limited quantity or for a limited time, can dramatically increase its ①desirability, 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 ②easy to obtain, people tend to 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, prompting customers to make ③hurried purchase decisions they might otherwise postpone or reconsider. Experimental studies confirm that identical products are rated as more desirable and often command ④higher prices when framed as scarce than when the same products are presented as widely and continuously available. Consumers who later reflect calmly on such purchases frequently discover that the item's actual usefulness fell well short of the ⑤urgency they experienced at the moment of decision.

As private companies develop the technology to mine asteroids for rare metals and water, a legal question once confined to science fiction has suddenly become ① urgent: who, if anyone, owns the resources of outer space? Existing international treaties state that no nation may claim sovereignty over celestial bodies, but they say remarkably ② little about whether a private company may extract and sell what it finds there. Some governments have already passed domestic laws granting their own companies rights to material mined in space, a move that other nations view as a ③ collective attempt to settle a question that should be decided collectively. Supporters of space mining argue that new resources could ④ ease shortages on Earth and fund further exploration, while critics ⑤ warn that treating space as an open frontier for extraction risks repeating the same mistakes that colonization caused on Earth.

Attention, students and teachers! Our school is starting a new campaign called 'Bring Your Own Bag.' Starting next Monday, the school store will no longer offer free plastic bags to customers. Instead, we ①encourage everyone to bring a reusable shopping bag from home. Plastic bags, which are made from petroleum, take hundreds of years to break down in the environment. In contrast, a cloth bag can be used again and again for many years. Therefore, using a reusable bag is a simple habit that ②protects sea animals and ③increases pollution. For example, students who bring their own bags will receive a small sticker as a ④reward. However, students who forget their bags may still purchase a paper bag for a small fee. We hope every student will join this easy and meaningful campaign. Thank you for helping our school become ⑤greener.

The Hopeful Start Workshop will be held on January 10th at the Green Hill Community Center. This event is designed to _______________. The workshop will run from two to four in the afternoon, and participants will learn simple methods for writing goals that are specific and easy to measure. The workshop is open to all middle and high school students, and no experience is required. Registration is free, but seats are limited to thirty people, so early sign-up is recommended.

Among the many strategies proposed to remove carbon dioxide from the atmosphere, one of the oldest draws on an agricultural technique predating modern industry, converting organic material into a stable form of charcoal known as biochar. (A) When mixed into farmland, biochar also improves soil structure, retaining moisture and nutrients otherwise lost, which can boost crop yields in depleted soils. For example, farmers cultivating nutrient-poor tropical soils have reported measurable increases in productivity after adding biochar. (B) Biochar is produced through pyrolysis, a process in which crop residues or wood chips are heated in an environment with little or no oxygen, preventing the material from burning away as in an open fire. This process leaves behind a carbon-rich solid that resists decomposition far longer than raw organic matter, locking carbon in a form remaining stable in soil for centuries. (C) Nevertheless, researchers caution that the climate benefits of biochar depend on the feedstock and method used, since poorly managed pyrolysis can release as much carbon as it sequesters, undermining its own purpose.

Telemedicine has sparked debate among healthcare professionals about its proper role in modern medicine. (A) Critics counter that virtual visits cannot fully substitute for physical examinations, which remain essential for diagnosing certain conditions accurately. (B) Most experts, weighing both sides, conclude that telemedicine works best as a complement to, rather than a replacement for, traditional care. (C) Supporters point out that virtual visits save time and extend healthcare access to patients living far from hospitals.

Breaking a big goal into smaller pieces can make it much easier to achieve. (A) Over time, these small successes add up, just like bricks gradually forming a strong wall. (B) For example, instead of aiming to master English in a year, try learning just twenty new words in a week. (C) Completing each small step gives you a sense of success, which motivates you to keep moving forward.

Parents can influence their children's career choices in very different ways. (A) In contrast, some parents quietly share their own unfinished dreams instead of giving direct instructions. (B) Other families take a much gentler approach, allowing children to explore their own interests freely. (C) Some parents openly push their children toward careers they consider safe and stable.
