A cluster of neurons smaller than a pea can now spontaneously ①organizing itself into layered structures that mimic, in miniature, the architecture of a developing human brain. Grown from stem cells coaxed to follow the same developmental cues that guide an embryo, these brain organoids have begun ②firing electrical signals in patterns that faintly resemble the activity recorded in an infant's brain. For researchers studying disorders such as autism or schizophrenia, this offers something long unavailable: a living model of human brain development that can be ③observed and manipulated directly, without ever touching an actual patient. Because organoids lack sensory organs, a body, or any connection to the outside world, most neuroscientists argue that the structures cannot generate anything ④resembling subjective experience, however brain-like their electrical activity may appear. Even so, the pace at which these organoids are growing more complex has convinced some ethicists that the field would benefit from ⑤establishing clear boundaries now, before the science outruns the conversation about what it means.

Sociologist Karl Mannheim argued that individuals ①who come of age during the same historical period tend to share a distinctive outlook shaped by the events, technologies, and crises that defined their formative years, a phenomenon he called a generational unit. Because each generation absorbs its foundational assumptions during adolescence and early adulthood, when identity ②are still forming, later generations raised amid different circumstances often ③develop noticeably different values regarding work, authority, and communication, even within the same family. This divergence produces what is commonly called a generational gap, most visible when older members of a household ④interpret a younger relative's habits as a rejection of tradition rather than a rational adaptation to a genuinely different social environment. Mannheim cautioned against viewing either generation as simply right or wrong, insisting instead that each generation's worldview ⑤reflects a coherent response to the particular historical conditions it encountered.

Traditional industrial systems have relied on a linear model of production, in which raw materials are extracted, transformed into goods, and eventually discarded as waste. This approach treats natural resources as if ①unlimited and disposal as if costless. A circular economy proposes an alternative framework in which materials are kept in continuous use through reuse, repair, and recycling, thereby ②reducing the extraction of virgin resources. Central to this model is the notion that waste, rather than being an inevitable byproduct, can be redesigned as a resource for another process, much as fallen leaves nourish the trees that shed them. For example, manufacturers design products so that components can be disassembled and reused in new items once their original function ends. Some companies also lease equipment instead of selling it outright, retaining responsibility for refurbishment. Because such practices lessen dependence on finite raw materials, they ③increase the environmental damage caused by mining. Consequently, the circular economy is increasingly regarded as a ④viable economic strategy that ⑤conserves resources for future generations.

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 ①familiar 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. This simplicity, however, is also the source of its most ②occasional criticism. Because the footprint aggregates dissimilar impacts, such as carbon emissions and water scarcity, into one composite figure, it can ③obscure 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, ④concealing damage that demands urgent attention. Furthermore, the method assumes that all bio-productive land is roughly ⑤interchangeable, treating a hectare of forest as equivalent to a hectare of farmland, even though the two provide markedly different ecological functions.

Imagine a teleportation device that scans every atom in your body, transmits that information to a distant station, and reconstructs an exact physical duplicate there, while destroying the original body in the process. From the traveler's point of view, stepping into the machine and stepping out on the other side would feel utterly seamless, complete with continuous memories. Philosophers, however, are troubled by a version of the same device that malfunctions: instead of destroying the original, it leaves the original body intact while still creating a perfect duplicate elsewhere. Now two people exist, each with identical memories and an equally strong claim to being the original traveler, and there is no principled way to say that one of them is the real continuation of the person who entered the machine. This malfunction reveals that _______________.

When an oil tanker ruptures and crude spreads across open water, cleanup crews increasingly reach not only for skimmers and floating booms but also for something far smaller: bacteria that eat oil. Certain naturally occurring microbes possess enzymes capable of breaking hydrocarbon molecules apart, using the carbon as an energy source and gradually converting a toxic slick into carbon dioxide and harmless byproducts. Bioremediation, as this approach is called, works far more slowly than mechanical cleanup, often taking months rather than days, but it can reach contamination trapped in soil or sediment that skimmers and booms can never reach. Scientists have learned to accelerate the process by adding nutrients that help native microbial populations multiply faster, or in some cases by introducing engineered strains selected specifically for their appetite for a particular pollutant. _______________.

A cotton plant that manufactures its own insecticide sounds like science fiction, yet it has been growing in fields around the world for decades. (A) Supporters point to yield increases and reduced pesticide spraying documented across millions of hectares, while critics worry about resistance evolving over time, which is why regulatory agencies in most countries now require extensive testing before a genetically modified crop reaches the market. (B) Other genetically modified crops carry a gene that allows them to survive direct exposure to a particular herbicide, letting farmers spray a field to kill weeds without harming the crop growing among them. (C) Scientists achieved this by isolating a gene from a soil bacterium that produces a protein toxic to specific insect pests but harmless to humans, then inserting that gene into the plant's own genome so that every cell manufactures the protective protein.

Imagine a brilliant scientist named Mary who has spent her entire life inside a black-and-white room, learning everything physical science could ever teach about color. (A) Despite this complete physical knowledge, Mary herself has never actually seen a color, since every book, screen, and object in her world has been carefully restricted to shades of gray. (B) Suppose that one day Mary is finally released from the room and shown a ripe red tomato for the first time. (C) Philosopher Frank Jackson argued that Mary would learn something entirely new at that moment, namely what it actually feels like to see red, even though she already possessed every physical fact about color.

Contemporary sociologists continue to debate whether digital networks represent a genuine revival of Gemeinschaft-style community or merely extend Gesellschaft's impersonal logic into new, more intimate-seeming spaces. German sociologist Ferdinand Tönnies distinguished between two fundamentally different forms of social organization, which he termed Gemeinschaft and Gesellschaft. ( ① ) Gemeinschaft, often translated as community, describes relationships bound by close kinship, shared tradition, and face-to-face familiarity, typical of small villages. ( ② ) Gesellschaft, often translated as society, describes relationships organized around impersonal contracts, self-interest, and formal law, typical of large cities. ( ③ ) Tönnies did not regard one form as simply superior to the other; rather, he saw the shift from Gemeinschaft toward Gesellschaft as a defining feature of modernization. ( ④ ) This shift brought greater efficiency and individual freedom while weakening the dense emotional bonds that once held communities together. ( ⑤ )

주어진 문장: This question has motivated economists to search for empirical patterns linking national income levels to measurable indicators of environmental quality. Economists have long debated whether prosperity and environmental quality are fundamentally opposed, or whether the relationship between them changes shape as an economy matures. ① The Environmental Kuznets Curve, a hypothesis borrowed from earlier theories of income inequality, proposes that pollution initially rises alongside economic growth before eventually declining once a society crosses a certain threshold of wealth. ② In its early stages, industrializing nations prioritize output over conservation, treating clean air and water as expendable costs of development to be addressed later. ③ Beyond a certain point, however, rising incomes generate both the technological capacity and the political will to demand stricter regulation, so degradation begins to reverse even as production keeps expanding. ④ Some scholars regard this trajectory as a reassuring paradox, suggesting that the very growth blamed for ecological harm may eventually finance its own repair. ⑤ Critics, by contrast, argue that the curve rests on a narrow selection of pollutants that happen to decline with wealth, while ignoring greenhouse gases and resource depletion, which show no comparable tendency to fall. ① ② ③ ④ ⑤
