Change blindness refers to a striking limitation of human perception in which observers fail to notice substantial alterations to a visual scene, provided the change occurs ① during a brief disruption such as an eye movement or a momentary obstruction. In a now-famous demonstration, researchers showed ② participants two versions of a photograph in alternation, separated by a short blank screen, and asked them to identify what had changed. Even when an entire building disappeared or a person's clothing shifted color, many viewers stared at the picture without detecting ③ anything unusual. This phenomenon occurs because visual attention, rather than passively recording every detail like a camera, actively selects only a narrow subset of information for processing at any given moment. Whatever falls outside that narrow spotlight represents ④ only sparsely, if at all, leaving it vulnerable to being overwritten without notice. Consequently, change blindness demonstrates that our impression of a rich, complete visual world is, to a surprising extent, an illusion constructed ⑤ by the mind, not a faithful record of external reality.

For our club's spring project, we ①were told to create a sculpture using only materials collected from the school's recycling bins, and my first reaction was disappointment at not being allowed to buy proper art supplies. Sorting through flattened cardboard, broken umbrella frames, and plastic bottle caps, I initially ②saw nothing but trash. My perspective shifted once a senior member showed me a piece she ③had built the previous year, a bird made entirely of bent bicycle spokes and bottle caps, each cap functioning as a single feather. She explained that upcycling art forces a creator ④noticing a material's natural shape and texture rather than simply painting over it, which often produces more original results than starting with a blank, expensive canvas. By the end of the project, our team had built a small forest of figures using nothing that anyone had paid for, and the exhibit visitors seemed more curious about our materials than about any technique we ⑤had used.

Sociologists use the term homophily to describe the tendency of people to form connections with others who share ①different backgrounds, opinions, or interests. This principle explains why classmates from the same major often become close friends, while coworkers with shared hobbies naturally gravitate toward one another. Because similarity reduces the effort required to understand another person's perspective, relationships built on shared traits tend to feel ②comfortable and require less negotiation. However, this same comfort can ③narrow the range of viewpoints someone encounters, since surrounding oneself with similar people limits exposure to different ideas. Social media platforms intensify this pattern through recommendation algorithms that suggest new friends based on shared interests or similar browsing history. As a result, users often find their online circles becoming increasingly ④homogeneous, filled with people who think and behave much like themselves. Recognizing this tendency allows individuals to make ⑤deliberate efforts to broaden their social networks.

Last week, I started feeling tired and had a mild headache every afternoon at school. At first, I thought I was just stressed about exams, but my mother told me it might be air-conditioning sickness, which happens when ___________. After doing some research, I learned a few simple ways to prevent it, such as wearing a light jacket indoors, drinking warm water, and stretching every hour.

Attention, all students! Our school will hold the New Year Goal Presentation Day on Friday, January 30th, in the main auditorium, where ___________. Each presentation should last no longer than two minutes and may include a poster or simple props to explain the goal clearly. Students who wish to participate must submit a short outline to their homeroom teacher by January 23rd.

Last month, I attended a three-day career camp during summer vacation. On the first day, I chose the broadcasting workshop, where students practiced writing short news scripts and reading them in front of a camera. It was harder than I expected, since staying calm while a camera recorded my every move felt strange at first. By the second day, however, I began to enjoy the challenge, and my confidence grew with each attempt. The instructors, who all had real broadcasting experience, gave ___________ rather than simple praise, which helped us improve quickly.

Millions of people now wear devices that continuously track their heart rate, sleep patterns, and daily activity, generating an intimate stream of health data. (A) In practice, however, the terms of service that few people read often grant the manufacturer broad rights to store, analyze, and even sell anonymized versions of that data. (B) Users generally assume this information belongs to them, since it is drawn directly from their own bodies. (C) This arrangement becomes especially troubling when health data influences decisions far beyond fitness, such as insurance premiums or employment screening.

Have you ever thrown away an old pair of jeans simply because they no longer fit? Instead of discarding them, many people now turn old items into something new and useful. (A) However, upcycling differs from ordinary recycling, which usually breaks materials down before making something new. In upcycling, the original material keeps most of its form while gaining a fresh purpose. Therefore, choosing to upcycle rather than throw items away can reduce waste significantly. This small shift in thinking allows old objects to enjoy a meaningful second life. (B) This creative process, called upcycling, transforms unwanted objects into products with greater value than before. (C) For example, a worn pair of jeans can be cut and sewn into a sturdy bag or a small pouch. Old wooden pallets, once used for shipping, are often rebuilt into simple furniture such as tables and shelves.

Researchers who study teenagers have found a strong link between how well students sleep and how well they perform in school. (A) Students who sleep fewer than seven hours a night tend to score lower on tests of memory and attention than those who sleep eight or nine hours, even when the two groups study for the same number of hours. (B) One explanation is that sleep plays an active role in learning: during certain stages of sleep, the brain replays and strengthens information encountered during the day, converting fragile short-term memories into more durable long-term ones. (C) When sleep is cut short, this consolidation process is interrupted before it can finish, so material that seemed well understood the night before often feels unfamiliar the next morning. For this reason, some schools have begun rethinking early start times, reasoning that an extra hour of sleep might do more for test scores than an extra hour of studying ever could.

The software company, in turn, may argue that no algorithm can be expected to be perfect. Hospitals are increasingly adopting artificial intelligence tools that can scan medical images and flag potential tumors faster than experienced radiologists. ( ① ) When an AI system misses a diagnosis that a human doctor would likely have caught, responsibility becomes difficult to assign. ( ② ) The doctor may argue that they simply trusted a tool the hospital required them to use. ( ③ ) The hospital, meanwhile, may argue that the software company guaranteed its accuracy. ( ④ ) Until legal systems clarify this chain of responsibility, patients harmed by an algorithmic error may find themselves with no clear party to hold accountable. ( ⑤ )
