As cities have expanded across landscapes once covered with absorbent soil, impervious surfaces have turned stormwater from a resource that ①recharges groundwater into a hazard that floods streets and carries pollutants into waterways. Green infrastructure, which ②mimic the hydrological functions that natural landscapes once performed, offers planners a way to treat the city as a sponge rather than a rigid drainage pipe. Rain gardens, shallow depressions planted with deep-rooted vegetation, are designed to capture runoff from rooftops, ③allowing it to filter slowly through soil before reaching underground aquifers. Permeable pavement, made of porous materials ④that let water pass directly through, serves a similar purpose along sidewalks, where asphalt would remain impenetrable. For example, cities that replaced pavement with permeable alternatives have reported notable 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 ⑤requires structural reinforcement. Consequently, municipalities now regard green and gray infrastructure as complementary systems, each compensating for the other's limitations.

Biodegradable plastics have been promoted as a promising solution to plastic waste, since they ①are designed to decompose into natural substances rather than persist for centuries. Manufacturers derive these materials from renewable resources such as corn starch, blending them with additives that ②accelerates microbial breakdown once discarded. However, their environmental benefits are often exaggerated, largely because decomposition depends on specific conditions rarely ③found outside industrial composting facilities. 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. In addition, when mixed with conventional plastics in recycling streams, they can contaminate the process, ④weakening the quality of materials produced afterward. 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 ⑤providing the precise conditions decomposition demands.

As more schools shift toward digital textbooks and online assignments, a student without reliable internet access at home faces a disadvantage that has little to do with talent or effort. During recent years, this gap became ①impossible to ignore, as families in rural areas or low-income neighborhoods struggled to complete schoolwork that assumed a stable connection and a personal device. Some policymakers initially treated internet access as a ②convenience, comparable to cable television, rather than as infrastructure essential to modern life. That assumption is increasingly being reconsidered, particularly as more essential services move online by default. Closing this divide will require ③far less than simply distributing devices; it will demand ④sustained investment in the physical networks that carry information into every home, ⑤regardless of income or location.

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 ①stable form of charcoal known as biochar. Biochar is produced through pyrolysis, a process in which crop residues or wood chips are heated in an environment with little or no oxygen, preventing the material from burning away as in an open fire. This process leaves behind a carbon-rich solid that ②accelerates 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 ③boost crop yields in depleted soils. For example, farmers cultivating nutrient-poor tropical soils have reported ④measurable 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, ⑤undermining its own purpose.

Speed-reading courses promise a simple result: read several times faster while understanding just as much as before. Some students do learn to move their eyes faster after a short course. However, researchers who study reading have found a serious problem with these claims. Understanding a text depends not just on how quickly your eyes move across it, but on how deeply your brain processes each sentence and connects new ideas to what you already know. In careful studies, speed-reading graduates often score no better on comprehension tests than ordinary readers who read at a normal pace. This suggests that _______________.

After a viewer finishes an episode, a streaming service rarely leaves the choice of what to watch next entirely up to chance. Instead, a recommendation algorithm compares that viewer's habits with patterns drawn from millions of other users, then ranks thousands of titles in order of predicted interest. The system is not without drawbacks, however. Because the algorithm favors titles similar to what a viewer already enjoys, it can quietly narrow someone's exposure to unfamiliar genres, directors, or cultures, creating a comfortable but repetitive bubble. Some platforms have begun inserting occasional wildcard suggestions, deliberately unrelated to past viewing habits, in an attempt to _______________.

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 minimizes energy demand through the building's own structure rather than through mechanical systems. (A) Consequently, many architects regard passive house design not as a luxury for wealthy homeowners but as a practical model capable of reshaping mainstream construction. (B) 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. (C) 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.

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. (A) 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. (B) 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 are drawn with more confidence than the data can support. (C) 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. 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.

The same technology, researchers realized, could be pushed even further, from generic drug screening toward medicine tailored to a single individual. A liver no longer has to sit inside a human body to be studied closely. ( ① ) By coaxing stem cells to organize themselves within a nutrient-rich gel, scientists can now grow miniature three-dimensional structures called organoids, which reproduce much of the architecture and function of a real organ despite being no larger than a grain of rice. ( ② ) Unlike flat cultures grown on a plastic dish, which lose many of the cues that guide normal development, organoids let cells interact in three dimensions much as they would inside the body. ( ③ ) This yields tissue that behaves in strikingly realistic ways. ( ④ ) This fidelity has made organoids invaluable for testing how a drug affects human tissue before any patient is exposed, sparing researchers much of the burden of relying on animal models alone. ( ⑤ ) Some laboratories have even grown organoids from a single patient's own cells, raising the possibility of trialing a treatment on a miniature copy of that patient's organ before committing to an actual course of therapy.

주어진 문장: Each of these exchanges is deliberately planned so that a byproduct considered worthless by one company becomes a valuable resource for its neighbor. Conventional industrial zones typically operate as isolated facilities, each purchasing raw materials independently and disposing of waste without regard for neighboring plants, even when one factory's discarded byproduct could serve as valuable input for another. ① An eco-industrial park reorganizes this arrangement by clustering diverse companies within a single area and encouraging them to exchange materials, energy, and water through a practice known as industrial symbiosis. ② A power plant's surplus heat, for example, might be piped to a nearby greenhouse, while a food processing facility's organic waste could be converted into biogas that powers another factory's equipment. ③ Such exchanges require companies to coordinate schedules and share information they might otherwise regard as proprietary, a level of cooperation rarely achieved without deliberate institutional support. ④ Local governments therefore often play a coordinating role, mapping which industries could exchange resources and providing incentives for companies willing to participate. ⑤ Consequently, eco-industrial parks have come to be seen as a model capable of reducing both waste disposal costs and raw material expenses simultaneously. ① ② ③ ④ ⑤
