Even a modest level of dehydration, as little as two percent of body weight ①lost through sweat, can measurably reduce an athlete's endurance and cognitive sharpness during competition. As fluid levels drop, blood volume decreases, ②forcing the heart to work harder to deliver the same amount of oxygen to working muscles, which accelerates fatigue. Dehydration also impairs the body's ability ③to regulate its own temperature, since sweating is the primary mechanism for releasing excess heat during intense exercise. Athletes competing in hot, humid conditions face a particularly difficult balance, because sweating heavily to stay cool simultaneously ④depletes the very fluids needed to sustain performance. For this reason, sports scientists generally recommend a hydration strategy ⑤tailoring to an individual athlete's sweat rate and the specific conditions of the event.

Jimin joined the school band club in March, but she ①had never performed before an audience. The club's first concert was only two weeks away, and everyone felt nervous. During practice, her hands shook whenever the song reached the chorus, and she kept missing the same chord. Instead of laughing at her mistakes, the other members waited patiently and ②playing the section again with her. The drummer, Suho, suggested that she ③focus on just one part at a time. Slowly, her fingers grew more confident, and the chord ④that once felt impossible began to feel natural. The club practiced until the melody sounded smooth the night before the concert. When Jimin walked onto the stage, she thought of her friends' patience instead of her fear. The audience clapped warmly, and she realized ⑤her club's support had made the difference.

Blockchain technology was originally promoted as a way ①to remove the need for trusted middlemen, allowing strangers to exchange value directly and verify transactions through a shared, tamper-resistant ledger rather than through a bank or government agency. In theory, this design ②distributes power away from any single institution and toward the network as a whole. In practice, however, a small number of large players have come to dominate many blockchain networks, ③controlled enough computing power or currency to influence outcomes that were supposed to be decided collectively. Critics note a further irony: when something goes wrong, there is often no institution left ④to appeal to, since the entire system was designed precisely to eliminate that kind of central authority. Whether decentralization can survive this concentration of power ⑤remains one of the technology's most unresolved questions.

Good morning, residents of Green Apartment! We would like to introduce a simple way to protect our environment. Used batteries, ①what contain harmful chemicals, should never be ②thrown away with regular trash. If these chemicals leak into the soil, they can pollute water and harm plants. Therefore, our building has installed a special collection box for used batteries near the main entrance. Please place your old batteries inside this box instead of the trash can. The box, ③which is emptied every month, is easy for anyone ④to use. For example, small button batteries from watches and toys can also be dropped in the box. However, batteries ⑤that are still working should not be thrown away at all. We appreciate your effort to keep our neighborhood clean and safe. Thank you for your cooperation and kindness.

When people fail to reach a goal, they often feel ①embarrassed and want to give up. However, the way a person thinks about failure can change what happens next. Some people believe failing means they simply lack ability, so they ②stop trying. Others see failure differently: they treat it as ③useless information that shows what needs to change. For example, a student who fails a math test might later ask the teacher which questions were weak points and study those areas more ④carefully. Over time, people who view failure as a lesson rather than a final judgment tend to keep working toward their goals, even after several ⑤setbacks.

Conventional industrial zones typically operate as isolated facilities, each purchasing raw materials independently and disposing of waste without regard for neighboring plants, even when one factory's discarded byproduct could serve as valuable input for another. An eco-industrial park _______________. A power plant's surplus heat, for example, might be piped to a nearby greenhouse, while a food processing facility's organic waste could be converted into biogas that powers another factory's equipment. Such exchanges require companies to coordinate schedules and share information they might otherwise regard as proprietary, a level of cooperation rarely achieved without deliberate institutional support. Local governments therefore often play a coordinating role, mapping which industries could exchange resources and providing incentives for companies willing to participate. Consequently, eco-industrial parks have come to be seen as a model capable of reducing both waste disposal costs and raw material expenses simultaneously.

The classification of platform workers has become one of the most debated issues in modern labor law. (A) For this reason, companies generally prefer classifying these workers as independent contractors rather than full employees. (B) Being classified this way, however, means workers miss out on protections such as minimum wage and paid leave. (C) Employee status requires companies to provide benefits and follow strict labor regulations, which increases operating costs.

주어진 문장: Because this competition can occur in either temporal direction, learners cannot avoid it simply by focusing on new material, which is precisely why deliberately spacing out study sessions matters so much. Memory researchers have long recognized that learning is not simply a matter of accumulating information without cost. Newly acquired material can collide with what the mind already holds, producing measurable disruptions in recall. ( ① ) When earlier knowledge interferes with the retrieval of information learned afterward, psychologists call this proactive interference. This phenomenon explains why someone who memorized an old phone number for years may struggle to recall a new one. ( ② ) Conversely, when material learned later undermines the recollection of something acquired earlier, the process is labeled retroactive interference. This second mechanism explains why switching to a new keyboard layout can temporarily impair typing on a familiar one. ( ③ ) Both processes suggest that memories compete for the same limited retrieval pathways rather than resting in isolated compartments. ( ④ ) This insight carries real implications for how students approach studying multiple similar subjects. ( ⑤ ) Instead of cramming closely related material back to back, spacing out review sessions can reduce competition between overlapping traces. Varying study contexts further helps preserve accuracy for both old and new information alike.

For this reason, many economists argue that the real challenge is not the robots themselves, but the speed at which society is expected to adapt to them. Factories that once employed hundreds of workers on an assembly line now run with a fraction of that staff, as robotic arms handle tasks that used to require human hands. ( ① ) Economists have long debated whether this shift destroys jobs or simply transforms them. ( ② ) Historical evidence offers some comfort: previous waves of automation eventually created new categories of work that no one had predicted. ( ③ ) However, critics point out that earlier transitions unfolded over generations, giving workers time to retrain, whereas today's robots are being deployed at a pace that leaves little room for adjustment. ( ④ ) A factory worker displaced this year cannot simply wait for a new industry to emerge decades from now. ( ⑤ )

Consequently, even seasoned professionals who believe themselves immune to such influence often fail to notice how much their final judgment has shifted. The anchoring effect can be surprisingly resistant to conscious correction. ( ① ) Even when individuals are explicitly warned in advance that a number they are about to see is randomly generated and therefore meaningless, their subsequent estimates still drift toward that arbitrary figure. ( ② ) This occurs because the mind uses the initial number as a starting point and then adjusts insufficiently away from it, a process that leaves the final judgment biased toward the anchor. ( ③ ) Experimental studies have repeatedly demonstrated this effect across a wide range of tasks, from estimating historical dates to appraising real estate. ( ④ ) The bias persists not because people lack expertise, but because the adjustment process itself is inherently incomplete. ( ⑤ ) Awareness of the anchoring effect, therefore, does not guarantee immunity from it, which is precisely what makes the bias so difficult to counteract in practice.
