Every semester, students groan when the fire alarm rings for another routine drill, ①filing out of the building as if the exercise were simply a break from class. This casual attitude, however, overlooks why the drill exists in the first place. During an actual fire, thick smoke can fill hallways within minutes, ②cutting visibility to almost nothing and making it dangerously easy to panic or take a wrong turn. Repeating the same evacuation route again and again trains the body ③to move automatically, even when the mind is too frightened to think clearly. Firefighters note that students who ④have practiced an escape route calmly walk toward the nearest exit purely out of habit, while those unfamiliar with the building often freeze or hesitate at doorways. A fire drill that feels pointless in the classroom can therefore ⑤becoming the very reason a real evacuation succeeds without injury.

A smart thermostat that learns a family's daily rhythm can lower the temperature automatically before everyone wakes up cold, while smart lights ①that follow a resident's schedule no longer need to be switched on and off by hand. These small conveniences rest on a shared foundation: sensors collect data about temperature, motion, and light throughout the home, and an algorithm gradually learns ②which settings match each household's actual habits rather than a factory default. Over months of use, the system becomes noticeably better at ③anticipate needs, often adjusting settings moments before a resident would have reached for a switch. Yet convenience comes with a trade-off that many households ④overlook. Every one of these small adjustments depends on constant data collection, meaning that a detailed record of when people wake, leave, and return home is quietly ⑤being stored somewhere beyond their immediate control.

Psychologist Leon Festinger introduced social comparison theory, which explains that people ①evaluate their own abilities and opinions by comparing themselves with others. According to this theory, individuals engage in upward comparison when they measure themselves against someone who appears more ②successful, attractive, or accomplished. For instance, a teenager browsing vacation pictures posted by classmates may begin to feel that her own ordinary life is somehow ③inadequate. Unlike comparing oneself with someone in a similar position, which can sometimes ④boost confidence, upward comparison frequently triggers envy, dissatisfaction, and lower self-esteem. Researchers have found that frequent upward comparison online is linked to ⑤lower depression and anxiety.

Consider a large heap containing ten thousand grains of sand. Nearly everyone agrees that removing a single grain from such a heap leaves another heap behind; surely one grain could never make the difference between a heap and a non-heap. Yet if this principle is applied repeatedly, grain by grain, the heap eventually shrinks to a single lonely grain, or even to no grains at all, and logic alone seems to force us to accept that this final result still counts as a heap. Something has clearly gone wrong along the way, since no reasonable person would call one grain of sand a heap, but pinpointing exactly which single removal transformed a heap into a non-heap seems impossible. The puzzle exposes a deep discomfort with vague terms like "heap," "tall," or "bald," concepts that seem to admit no sharp boundary yet are used confidently in everyday language. Some philosophers conclude that _______________.

Many teachers and parents worry that today's teenagers are losing the ability to read long, complex texts. National test scores show a slow decline in reading comprehension over the past ten years, and some experts blame smartphones and short videos for shortening students' attention spans. Other researchers disagree with this simple explanation. They point out that teenagers today read constantly, just in different forms, such as text messages, captions, and online articles. According to this view, the real problem is not that students read less overall, but that _______________. A team of researchers recently found that students who read at least one full book every month scored noticeably higher on comprehension tests than students who mainly read short online posts.

Many people throw away items that they no longer need. However, more and more students have begun to give old belongings a new purpose through secondhand trading. (A) For example, a jacket that no longer fits your older sibling can become a treasure for someone else, and giving an item to a new owner is like giving a toy a second life. (B) Therefore, secondhand trading, which requires little effort, protects both your wallet and the environment, and small choices like this can make a big difference for our planet. (C) This practice takes place at flea markets or through simple online apps, and when you buy a secondhand item, you save money and reduce waste at the same time.

Every brand has a history, but not every brand knows how to tell it well. (A) For example, a small shoe company once shared the story of its founder's grandfather, who had repaired shoes for workers in need. (B) Consequently, other companies began investing in storytelling as a core part of their marketing strategy. (C) Stories like this create emotional connections that plain advertisements rarely achieve on their own.

At first, Minji did not know how to fix the tension she had caused during rehearsals. (A) Soon, other members began doing the same, and rehearsals felt warmer than before. (B) She decided to start each practice by praising one small thing a classmate had done well. (C) The next day, she tried her new idea, and the room grew quiet as everyone listened.

In short, an effective fueling plan treats carbohydrate loading as one tool among many, not a substitute for well-rounded nutrition. In the days leading up to an endurance event, many athletes deliberately increase their carbohydrate intake while reducing training volume, a practice known as carbohydrate loading. ( ① ) The strategy is designed to maximize the amount of glycogen, the storage form of carbohydrate, packed into muscle tissue before competition begins. ( ② ) Because glycogen serves as the primary fuel source during prolonged, intense exercise, entering an event with fuller stores can delay the point of exhaustion that runners often call hitting the wall. ( ③ ) Sports nutritionists caution, however, that the timing and composition of meals matter as much as the total quantity of carbohydrate consumed, since eating unfamiliar foods immediately before competition can cause digestive discomfort. Athletes are therefore advised to practice their nutrition strategy during training rather than experimenting with it for the first time on race day. ( ④ ) Beyond carbohydrates, adequate protein and micronutrient intake throughout the training cycle remains essential, since fueling strategy is only one part of a much larger nutritional picture. ( ⑤ )

주어진 문장: As a result, no single boundary can be evaluated in isolation from the others. Scientists have long searched for a way to describe, in a single coherent framework, the outer limits within which human activity can safely continue without destabilizing the planet's fundamental systems. ① The concept of planetary boundaries, introduced by earth-system researchers, identifies nine interconnected processes, including climate change, biodiversity loss, and nitrogen pollution, each possessing a threshold beyond which abrupt and irreversible change becomes likely. ② Unlike conventional environmental limits, often defined locally, these boundaries are framed at a planetary scale, reflecting the idea that the Earth functions as a single interdependent system rather than a collection of isolated regions. ③ Crossing one boundary, proponents argue, does not merely damage the system involved but can also destabilize others, since climate, oceans, and land are bound together by feedback loops that transmit disturbance across the system. ④ Some philosophers have likened this framework to a ship's safe operating margin, within which passengers may move freely without risking the vessel's stability. ⑤ Critics, however, contend that the boundaries are drawn with more confidence than the data can support. ① ② ③ ④ ⑤
