Scientists have long searched for a way to describe, in a single coherent framework, the outer limits within ①which human activity can safely continue without destabilizing the planet's fundamental systems. The concept of planetary boundaries, ②introduced by earth-system researchers, identifies nine interconnected processes, including climate change, biodiversity loss, and nitrogen pollution, each ③possessing a threshold beyond which abrupt and irreversible change becomes likely. Unlike conventional environmental limits, often defined locally, these boundaries are framed at a planetary scale, ④reflecting the idea that the Earth functions as a single interdependent system rather than a collection of isolated regions. 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. 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. Critics, however, contend that the boundaries ⑤is drawn with more confidence than the data can support.

Students often groan when a classic novel appears on their reading list, complaining that the language feels old-fashioned and the plot moves too ①slowly. It is true that classic literature can be ②easier to read than a modern bestseller written in casual, everyday language. Yet this very difficulty is part of why classics remain valuable for young readers today. Working through unfamiliar sentence patterns and vocabulary trains the brain to handle ③complex texts, a skill that transfers directly to other subjects and to standardized tests. Beyond language training, classic novels also explore themes such as jealousy, ambition, and loss that have not changed much across ④centuries. Readers often discover that a character written hundreds of years ago struggles with feelings that still feel ⑤familiar today.

It is often assumed that memory operates independently of bodily context, yet research suggests that this assumption deserves reconsideration. When information is learned under a particular physiological or emotional condition, retrieval tends to ①improve if that same condition is reinstated at recall, a phenomenon researchers call state-dependent memory. Individuals who study while mildly anxious, for instance, often recall material more ②accurately when tested under similarly anxious conditions than when tested while calm, even though calmness is typically considered more conducive to concentration. This finding should prompt educators to reconsider the assumption that a single optimal testing environment exists for every learner, since matching internal states across encoding and retrieval provides retrieval cues that a ③mismatched state cannot supply. Critics might argue that such effects are minor and inconsistent, yet accumulated evidence across pharmacological and emotional studies is ④easy to dismiss. Policymakers designing assessments should therefore weigh not only content difficulty but also the physiological continuity between preparation and examination, since ignoring this dimension risks ⑤underestimating certain students' actual knowledge.

Physical education class often feels like the one period of the day when students can finally move freely, which sometimes leads them to skip the warm-up routine that teachers insist on before any real activity begins. Cold muscles, however, are noticeably less flexible than warmed ones, and _______________. Coaches often compare an unwarmed muscle to a cold rubber band that snaps rather than stretches under sudden pressure.

Students are frequently told that where they study makes little difference, provided that they put in enough hours. Cognitive research on memory retrieval, however, suggests that this advice oversimplifies an important process. According to the encoding specificity principle, information becomes intertwined with the context in which it was originally learned. Cues present during encoding therefore facilitate retrieval far more effectively than cues encountered elsewhere. A striking demonstration involved divers who memorized word lists either underwater or on dry land. When tested later, _______________. This held true regardless of which environment that happened to be. This finding implies that reviewing material exclusively in a quiet bedroom may not adequately prepare a student for the noisy atmosphere of an actual examination hall. Rather than assuming that memorization is a context-free process, students ought to consider deliberately varying study locations and conditions. Doing so would ensure that retrieval cues remain available regardless of how a future test is administered.

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 during a brief disruption such as an eye movement or a momentary obstruction. In a now-famous demonstration, researchers showed 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 anything unusual. This phenomenon occurs because visual attention, rather than passively recording every detail like a camera, _______________. Whatever falls outside that narrow spotlight is represented 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 by the mind, not a faithful record of external reality.

A shocking headline can spread across social media within minutes, long before anyone checks whether it is actually true. (A) Simple habits can make a real difference, such as looking for the original source of a claim and checking whether other trustworthy outlets are reporting the same story. (B) To handle this flood of information, students today need a skill that previous generations rarely had to practice: checking a source before believing it. (C) Studies show that false stories often travel faster than accurate ones, partly because surprising or emotional claims get shared more quickly than careful, balanced reporting.

Many students imagine a librarian simply sitting behind a desk and stamping books. (A) According to Ms. Han, the most rewarding moment is not organizing shelves but watching a student who once avoided reading finally ask for a second book in the same series. (B) Ms. Han, who has worked at a school library for over ten years, says that image is far from accurate, since a large part of her job involves choosing which new books to buy. (C) She also spends hours training students to search databases and judge whether an online source is trustworthy, a skill she considers just as important as reading itself.

주어진 문장: Yet not everyone finds this reassurance convincing. Few ideas in policy debate provoke as much philosophical unease as the notion that a government might deliberately steer citizens toward better choices while leaving every option technically available. ( ① ) Defenders insist that freedom is preserved as long as no option is banned and no penalty is attached, arguing that a citizen who is merely steered, rather than coerced, remains free to choose otherwise. ( ② ) Critics counter that this defense rests on an impoverished notion of liberty, one that ignores how engineered defaults and calculated framing can shape decisions just as powerfully as an outright prohibition would. ( ③ ) If a policy is designed because officials expect it to bypass conscious deliberation, these critics ask, can the resulting choice still be called autonomous, even though no law was broken? ( ④ ) The dispute ultimately turns on what freedom actually requires: the mere absence of coercion, or a decision-making process that remains transparent and undistorted. ( ⑤ ) Until this question is settled, every new intervention promising to help citizens choose better will continue to invite suspicion of quiet manipulation.

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
