Imagine a distant planet ①identically to Earth in every visible respect, except that the clear liquid its inhabitants call "water" is not H2O but a different compound, XYZ, that happens ②to look, taste, and behave exactly the same. When an Earthling and a Twin Earthling each say the word "water," they seem to mean the same thing, since neither could tell the substances apart without a chemistry lab. Philosopher Hilary Putnam ③used this scenario to argue that the meaning of a word is not determined solely by what happens inside a speaker's head. Even though the two speakers hold identical thoughts and mental images when they use the word, their statements refer to two different substances, because the underlying chemical composition, not personal belief, ④fixes what a word ultimately picks out. Meaning, Putnam concluded, depends partly on the world outside the mind, not merely on the private mental states of ⑤whoever happens to be speaking.

Economists have long debated whether prosperity and environmental quality are fundamentally opposed, or whether the relationship between them ①changes shape as an economy matures. The Environmental Kuznets Curve, a hypothesis ②borrowed 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. In its early stages, industrializing nations prioritize output over conservation, ③treats clean air and water as expendable costs of development to be addressed later. Beyond a certain point, however, rising incomes generate both the technological capacity and the political will ④to demand stricter regulation, so degradation begins to reverse even as production keeps expanding. Some scholars regard this trajectory as a reassuring paradox, suggesting that the very growth ⑤blamed for ecological harm may eventually finance its own repair. 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.

Physicist Erwin Schrödinger devised a now-famous thought experiment not to describe an actual laboratory procedure, but ①to expose an absurdity hidden within a leading interpretation of quantum mechanics. Imagine a cat sealed inside a closed box together with a radioactive atom, a Geiger counter, and a vial of poison gas ②rigged to break open the instant the atom decays. Because the atom's decay is governed by genuine quantum randomness, standard quantum theory describes the atom, before anyone looks, ③as existing in a superposition of having decayed and not having decayed at the same time. If the theory is applied consistently to the entire box, the cat itself would have to ④be considered simultaneously alive and dead until an observer opens the lid and looks inside. Schrödinger intended this image to sound obviously ridiculous, using the cat's absurd fate to question whether the act of observation truly determines physical reality, or whether the mathematics is simply being pushed further than it ⑤ever meaning to go.

Cities are frequently several degrees warmer than the surrounding countryside, a phenomenon ①known as the urban heat island effect, which intensifies in summer and threatens public health. This disparity arises largely because asphalt and concrete absorb solar radiation during the day and slowly release it as heat throughout the night, ②preventing urban areas from cooling down. To address this problem, urban planners have begun implementing mitigation strategies ③designed to lower surface and air temperatures. One widely used solution involves reflective "cool" roofing ④engineered to reflect more sunlight than dark rooftops absorb. Another strategy, green infrastructure, incorporates rooftop gardens and tree-lined streets that ⑤provides shade while releasing moisture.

When a resource is shared among many users, none of whom bears the full cost of its depletion, _______________. This dynamic, famously labeled the tragedy of the commons, describes how shared pastures and fisheries can be degraded even when every participant privately understands the danger of overuse. A single herder who adds one more animal to a communal pasture gains the entire benefit of that addition, whereas the resulting damage to the grass is shared among other herders who depend on the land. Because self-interest offers no incentive to restrain consumption unilaterally, the resource tends to be exhausted long before any user intends such an outcome. For decades, economists assumed that only two remedies existed: strict regulation or the conversion of shared resources into private property. Elinor Ostrom challenged this assumption, however, by documenting communities that had sustainably managed fisheries and forests for generations through locally devised rules and mutual monitoring rather than external control.

Even highly capable individuals can make disastrous collective decisions once they are absorbed into a tightly knit group, a phenomenon psychologist Irving Janis termed groupthink. (C) Sociologists extend this analysis beyond small committees, noting that entire organizations can develop cultures that reward conformity and punish employees who raise inconvenient questions. (B) Within cohesive committees, boards, and advisory councils, members often prioritize consensus and group harmony over a rigorous evaluation of alternatives, silencing doubts rather than risking the discomfort of dissent. (A) Historical inquiries into policy failures and corporate disasters frequently reveal that critical information existed within the organization but never reached decision makers, because no one felt safe enough to voice it aloud.

As efforts to curb greenhouse gas emissions intensify, industries unable to eliminate carbon dioxide from their processes have turned to a technology known as carbon capture and storage. (A) Proponents argue that carbon capture and storage functions as a bridge technology, allowing heavy industries to keep operating while more sustainable alternatives are developed. For instance, cement and steel production, both of which release carbon dioxide as an unavoidable byproduct of chemical reactions, are considered prime candidates for this approach. (B) However, critics contend that the technology remains prohibitively expensive and that building pipelines requires investments few companies make voluntarily. Despite such concerns, many governments continue funding pilot projects, convinced that this technology will play an indispensable role in reaching emission targets. (C) This technology involves separating carbon dioxide from the exhaust of power plants before it is released into the atmosphere, then transporting the captured gas for underground injection. Once injected into porous rock formations, the gas is trapped beneath layers of impermeable rock that prevent it from escaping into the air.

This puzzling inconsistency is not, as it turns out, a matter of chance. Two patients diagnosed with the same disease and prescribed the same medication can respond in strikingly different ways, one recovering quickly while the other experiences little benefit or even harmful side effects. ( ① ) Precision medicine starts from the observation that this variation often traces back to differences buried in each patient's genome. ( ② ) These differences determine how efficiently a body absorbs, breaks down, or responds to a given drug. ( ③ ) By sequencing a patient's DNA before treatment begins, doctors can increasingly predict which medication is likely to work best and at what dose, replacing a strategy once described as one-size-fits-all with something closer to a tailored fit. ( ④ ) This approach has proven especially valuable in cancer treatment, where tumors from two patients with the same diagnosis may carry entirely different genetic mutations that respond to entirely different drugs. ( ⑤ ) Widespread adoption still faces real obstacles, since genetic sequencing remains expensive in many regions and few doctors have been trained to interpret the flood of genetic data such tests now produce.

Philosophers return to this old story again and again, not because they care about timber, but because it forces us to ask a far deeper question about identity itself. The ancient puzzle known as the ship of Theseus asks a deceptively simple question. ( ① ) If every plank of a wooden ship is replaced one by one over many years, is the vessel that eventually results still the same ship it once was? ( ② ) Most people's first instinct is to answer yes, since each individual replacement seems too small to erase the ship's identity. ( ③ ) The puzzle grows far sharper, however, once a second twist is introduced: suppose a careful collector gathered every discarded plank and reassembled them into a second vessel, built exactly as the original once stood. ( ④ ) Two ships would then exist side by side, each with an equal claim to being the genuine one, and no obvious way to decide between them. ( ⑤ ) Whether identity depends on continuous material, continuous form, or some deeper thread, no single answer has ever fully satisfied everyone who has taken up the question.

주어진 문장: Even so, long-term monitoring in several cities indicates that combining both approaches lowers total infrastructure costs more effectively than relying on either strategy alone. As cities have expanded across landscapes once covered with absorbent soil, impervious surfaces have turned stormwater from a resource that recharges groundwater into a hazard that floods streets and carries pollutants into waterways. ① 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 rigid drainage pipe. ② Rain gardens, shallow depressions planted with deep-rooted vegetation, are designed to capture runoff from rooftops, allowing it to filter slowly through soil before reaching underground aquifers. ③ Permeable pavement, made of porous materials that let water pass directly through, serves a similar purpose along sidewalks, where asphalt would remain impenetrable. ④ 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 requires structural reinforcement. ⑤ Consequently, municipalities now regard green and gray infrastructure as complementary systems, each compensating for the other's limitations. ① ② ③ ④ ⑤
