Sleep apnea is a disorder in which breathing repeatedly stops and restarts during sleep, often because the muscles at the back of the throat relax too much and block the airway. Each pause can last from a few seconds to over a minute, and it may occur dozens of times in a single night without the sleeper ever ① waking up fully. Because these interruptions rarely produce a clear memory the next morning, many people remain ② unaware that anything is wrong, even as chronic fatigue, headaches, and irritability build up over months. Doctors therefore rely less on a patient's own account of the night and more on objective measurements, such as overnight oxygen levels and airflow patterns ③ recording in a sleep laboratory. ④ Left untreated, the disorder has been linked to serious long-term risks, including high blood pressure and heart disease, which makes an accurate diagnosis far more urgent than its subtle nighttime symptoms might ⑤ suggest.

When consumers compare two products and assume that the one ①labeled "eco-friendly" is automatically the more sustainable choice, they often overlook the complexity involved in verifying such a claim. Life cycle assessment, commonly abbreviated as LCA, is a systematic method ②developed to evaluate the environmental impact of a product across every stage of its existence. This method examines raw material extraction, manufacturing, transportation, use, and disposal, ③compiling data on energy consumption and emissions generated at each stage. By tracing a product from its origin to its disposal, this approach reveals impacts that might otherwise remain hidden from consumers who ④sees only the finished item on a shelf. Without ⑤accounting for these earlier stages, a superficial comparison could mistakenly present the vehicle as entirely emission-free.

As cities have expanded across landscapes once covered with ①absorbent soil, impervious surfaces have turned stormwater from a resource that recharges groundwater into a hazard that floods streets and carries pollutants into waterways. Green infrastructure, which mimics the hydrological functions that natural landscapes once performed, offers planners a way to treat the city as a sponge rather than a ②rigid drainage pipe. Rain gardens, shallow depressions planted with deep-rooted vegetation, are designed to capture runoff from rooftops, allowing it to filter ③rapidly through soil before reaching underground aquifers. Permeable pavement, made of porous materials that let water pass directly through, serves a similar purpose along sidewalks, where asphalt would remain ④impenetrable. For example, cities that replaced pavement with permeable alternatives have reported ⑤notable reductions in flooding during storms that once overwhelmed sewers. However, engineers caution that green infrastructure cannot entirely replace conventional pipes in dense cores, where heavy runoff still requires structural reinforcement. Consequently, municipalities now regard green and gray infrastructure as complementary systems, each compensating for the other's limitations.

Devices that translate brain activity directly into digital commands have moved from laboratory experiments to real medical use, allowing paralyzed patients to control a robotic arm or type a message using thought alone. As the technology ① improves, some developers envision a future in which brain-computer interfaces extend beyond restoring lost function toward enhancing healthy minds. This prospect raises a philosophical question that medicine alone cannot answer: if a device can alter memory, mood, or decision-making, at what point does the assistance stop being a tool and start ② reshaping the very identity of the person using it. Neuroethicists argue that mental privacy, the ability to keep one's own thoughts ③ exposed to external access or manipulation, may need to be recognized as a fundamental right before this technology becomes ④ widespread. This concern is likely to grow ⑤ more urgent as the devices become more powerful.

As buildings account for a substantial share of global energy consumption, architects have increasingly turned to a design philosophy known as the passive house standard, which _______________. Central to this approach is airtight construction, in which continuous insulation and sealed joints prevent conditioned air from leaking outward, thereby reducing the heating and cooling loads conventional buildings require. Triple-glazed windows, oriented to capture sunlight in winter while shading interiors in summer, further stabilize indoor temperatures without relying heavily on furnaces or air conditioners. Ventilation systems equipped with heat exchangers also recover warmth from outgoing air, transferring it to incoming air so that comfort is maintained without excessive energy use. For example, some passive houses built in cold climates have reduced heating costs by more than ninety percent. Consequently, many architects regard passive house design not as a luxury for wealthy homeowners but as a practical model capable of reshaping mainstream construction.

Among the many strategies proposed to remove carbon dioxide from the atmosphere, one of the oldest draws on an agricultural technique predating modern industry, converting organic material into a stable form of charcoal known as biochar. Biochar is produced through pyrolysis, _______________. This process leaves behind a carbon-rich solid that resists decomposition far longer than raw organic matter, locking carbon in a form remaining stable in soil for centuries. When mixed into farmland, biochar also improves soil structure, retaining moisture and nutrients otherwise lost, which can boost crop yields in depleted soils. For example, farmers cultivating nutrient-poor tropical soils have reported measurable increases in productivity after adding biochar. Nevertheless, researchers caution that the climate benefits of biochar depend on the feedstock and method used, since poorly managed pyrolysis can release as much carbon as it sequesters, undermining its own purpose.

The ecological footprint, a widely cited measure of how much biologically productive land and water a population requires to sustain its consumption, has become one of the most familiar tools for communicating humanity's environmental impact. By converting diverse activities, from driving to eating meat, into a single unit of land area, the measure allows policymakers to grasp whether a lifestyle exceeds what the planet can regenerate. (A) Because the footprint aggregates dissimilar impacts, such as carbon emissions and water scarcity, into one composite figure, it can obscure important differences among problems that require distinct policy responses. A region might reduce its footprint by lowering carbon emissions while simultaneously depleting a local aquifer, yet the aggregate number could still appear to improve, concealing damage that demands urgent attention. (B) This simplicity, however, is also the source of its most persistent criticism. (C) Furthermore, the method assumes that all bio-productive land is roughly interchangeable, treating a hectare of forest as equivalent to a hectare of farmland, even though the two provide markedly different ecological functions.

주어진 문장: Such admiration is common, for instance, toward chess grandmasters, medical diagnosticians, or professional musicians who seem to recall vast bodies of specialized knowledge without visible strain. When people encounter an individual who appears to memorize enormous quantities of specialized information effortlessly, they often assume that person possesses an innate gift. ( ① ) Cognitive psychologists, however, contend that such feats rarely stem from raw talent alone. Instead, such feats arise from a learned skill known as chunking, whereby scattered pieces of information are consolidated into larger, meaningful units. ( ② ) A landmark study of chess players demonstrated this principle. When shown a board arranged according to plausible game positions, grandmasters reproduced the layout perfectly. ( ③ ) Yet when the same pieces were scattered randomly, their performance collapsed to the level of novices. This pattern reveals that expert memory is not larger in raw capacity but is instead organized around patterns accumulated through years of deliberate practice. ( ④ ) If chunking, rather than innate aptitude, underlies expert performance, then educators should stop treating talent as fixed and destiny-bound. ( ⑤ ) Curricula ought to be redesigned to cultivate pattern recognition explicitly, since doing so would grant far more students access to expertise once presumed reserved for the naturally gifted.

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

주어진 문장: Beyond these practical objections, some conservationists raise a more fundamental theoretical concern about what rewilding is ultimately trying to achieve. Rewilding, a conservation strategy that seeks to restore natural processes with minimal human interference, has gained attention as traditional conservation struggles to halt biodiversity loss. ① Rather than managing landscapes according to a fixed blueprint, rewilding projects often reintroduce key species, such as large predators, whose presence can trigger cascading effects. ② Advocates point to the reintroduction of wolves in certain parks, where predation altered grazing behavior, allowing riverside vegetation to recover and stabilizing soil that had long been eroding. ③ Skeptics, however, warn that rewilding can provoke serious conflict with nearby communities, particularly when predators prey on livestock or restored habitats limit land for agriculture. ④ Moreover, critics argue that restoring landscapes to an imagined pristine state is scientifically dubious, since ecosystems have long been shaped by human activity. ⑤ Compensation programs reimbursing farmers for livestock losses, alongside ecotourism initiatives creating local income, have proven essential to sustaining public support. Ultimately, rewilding succeeds not by removing human influence but by renegotiating the relationship between people and the wild species they must coexist with. ① ② ③ ④ ⑤
