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.

Psychologists studying human judgment often describe the mind as ①operating through two distinct systems rather than a single unified process. System 1 works quickly and automatically, ②generating impressions and snap judgments without any noticeable sense of effort, much as a driver instinctively brakes when a ball suddenly rolls into the street. System 2, by contrast, is slow, deliberate, and demanding, engaged only when a problem ③require careful calculation or conscious reasoning. Most daily decisions are handled almost entirely by System 1, which allows people ④to function efficiently without exhausting their limited mental resources. This efficiency comes at a cost, however, because System 1 relies on simple shortcuts that can produce systematic errors, and System 2 is frequently too lazy or too occupied to double-check them. As a result, a judgment often feels most confident precisely at the moment when it has skipped the careful scrutiny that could have caught its own mistake, leaving the thinker unaware of how easily the impression was ⑤formed.

Classical economic theory long assumed that decision makers gather all relevant information, calculate every possible outcome, and select the single option that maximizes their benefit. Herbert Simon, however, questioned this assumption, arguing that human beings operate under real constraints of time, knowledge, and mental capacity that make such ①exhaustive calculation practically impossible. Instead of searching ②endlessly for the theoretically perfect choice, people typically stop once they find an option that seems good enough to meet their immediate needs, a strategy Simon termed satisficing. A shopper comparing refrigerators, for example, rarely examines every model available; she instead sets a few practical criteria, such as price and size, and selects the first appliance that satisfies them ③adequately. This approach is not a failure of reasoning but rather a sensible adaptation to a world where information is ④costly and time is genuinely limited. Consequently, models assuming unlimited rationality often fail to predict actual behavior, while frameworks acknowledging these cognitive boundaries offer a far more ⑤unrealistic account of how ordinary decisions are actually made.

Skipping a proper warm-up before intense exercise might seem like a harmless way to save a few minutes, but the practice carries real physiological costs, since a cold muscle is stiffer and less elastic than a warm one. Gradually raising body temperature through light activity increases blood flow to the muscles and speeds up nerve signals between the brain and the muscle fibers. A proper warm-up also raises heart rate gradually, easing the cardiovascular system into strenuous work. As a result, _______________. For this reason, coaches treat warm-up routines not as optional preparation but as an essential part of training itself.

Whenever people discuss the future of reading, one debate never seems to end: e-books or paper books? (A) Fans of paper books, however, argue that something important is lost on a screen, since many readers say they remember a book's plot more clearly by recalling where a scene appeared on the page. (B) Supporters of e-books point out that a single device can hold thousands of titles, and readers can also change the font size or look up a word instantly. (C) Screens also invite distraction, since a single notification can pull a reader away from the story, and interestingly, most young readers do not choose one format forever.

Adaptive learning apps promise something no traditional classroom can easily offer: a lesson plan that adjusts itself to each individual student in real time. (A) As a student answers practice questions, the app tracks which concepts are mastered and which remain shaky, then quietly reshuffles the next set of problems to target the weaker areas. (B) Early studies suggest that this personalized pacing can help struggling students catch up faster than a one-size-fits-all worksheet ever could. (C) However, critics caution that an app cannot replace the encouragement, humor, and flexibility a human teacher brings to a lesson.

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

주어진 문장: Taken together, these shortcomings suggest that biodegradability alone cannot guarantee a meaningful reduction in plastic pollution. Biodegradable plastics have been promoted as a promising solution to plastic waste, since they are designed to decompose into natural substances rather than persist for centuries. ① Manufacturers derive these materials from renewable resources such as corn starch, blending them with additives that accelerate microbial breakdown once discarded. ② However, their environmental benefits are often exaggerated, largely because decomposition depends on specific conditions rarely found outside industrial composting facilities. ③ For example, a bag labeled biodegradable may take years, not the weeks advertised, to break down in a landfill or ocean, where temperature and microbial activity remain low. ④ In addition, when mixed with conventional plastics in recycling streams, they can contaminate the process, weakening the quality of materials produced afterward. ⑤ Some engineers therefore compare biodegradable plastics to a bridge that leads nowhere unless paired with infrastructure that completes the journey. Ultimately, realizing their genuine potential requires not only technological refinement but also facilities capable of providing the precise conditions decomposition demands. ① ② ③ ④ ⑤

In other words, the hardest part of reading is never the reading itself, but the moment just before it begins. Building a reading habit does not usually start with a big decision to read more. ( ① ) It often starts with very small, easy steps. ( ② ) Some students keep a book in their bag so that they always have something to read while waiting for a bus, and others choose a fixed time each day, like right before bed, to read for just ten minutes. ( ③ ) These small routines work because they lower the effort needed to begin. ( ④ ) Once a student sits down and opens a book, continuing to read the next page feels much easier than the first step of starting. Experts also suggest setting a very low daily goal, such as one page, instead of a strict page count that feels like homework. ( ⑤ ) Over weeks, these tiny actions add up, and reading slowly becomes something the student simply does, rather than something the student has to force.

Some students feel nervous about sharing their opinions at first, but most grow more confident after a few sessions. Many students think that reading a book quietly by themselves is enough, but book discussion classes add something that solo reading cannot provide. ( ① ) When students explain their ideas out loud, they often discover thoughts they did not even know they had. ( ② ) Teachers who use discussion classes report that students remember plot details and themes far longer than students who only read silently and take a quiz afterward. ( ③ ) This happens because talking about a book forces the brain to organize scattered impressions into a clear argument. ( ④ ) Discussion also teaches students to listen carefully, since they must respond directly to classmates instead of simply waiting for their own turn to speak. ( ⑤ ) For these reasons, many schools are now adding weekly discussion sessions to their reading programs, even for short stories that used to be assigned only as silent homework.
