Time travel to the past has long fascinated physicists and philosophers alike, but it also generates a famously troubling ①contradiction. Suppose a traveler journeyed backward in time and, through some combination of accident and intention, prevented their own grandfather from ever meeting their grandmother. If the grandfather never had children, the traveler themselves would never have been born, which means the traveler could never have existed to make the trip in the first place. Yet if the traveler never made the trip, the grandfather would have ②survived to meet the grandmother after all, allowing the traveler to be born and eventually travel back in time. The story therefore ③loops endlessly, undermining itself at every turn rather than settling into any stable outcome. Some physicists resolve the paradox by arguing that any consistent timeline must ④permit such self-defeating actions to succeed freely, while others propose that a traveler who alters the past simply branches off into a separate, parallel timeline instead, an idea many find ⑤appealing precisely because it avoids the contradiction altogether.

When consumers compare two products and assume that the one labeled "eco-friendly" is automatically the more ①sustainable choice, they often overlook the complexity involved in verifying such a claim. Life cycle assessment, commonly abbreviated as LCA, is a systematic method developed to evaluate the environmental impact of a product across every stage of its existence. By tracing a product from its origin to its disposal, this approach reveals impacts that might otherwise remain ②hidden from consumers who see only the finished item on a shelf. For example, an electric vehicle may produce no emissions while being driven, yet the mining of metals for its battery can generate ③substantial environmental costs elsewhere. Without accounting for these earlier stages, a ④superficial comparison could mistakenly present the vehicle as entirely emission-free. Therefore, researchers increasingly rely on life cycle assessment to make ⑤uninformed decisions rather than trusting labels alone.

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.

Imagine a man locked inside a room who does not understand a single word of Chinese, yet who possesses a giant rulebook written entirely in English. Slips of paper covered with Chinese characters are passed in through a slot, and by following the rulebook's instructions step by step, he produces replies that appear fluent to anyone outside. From the perspective of a native speaker reading the responses, the room seems to understand Chinese perfectly. Yet the man inside understands nothing at all; he is merely manipulating shapes according to formal rules, without grasping their meaning. This scenario was designed to challenge the assumption that a computer running a sophisticated program truly understands language simply because it produces convincing output. Passing every external test of intelligence, the argument suggests, is not the same as possessing genuine understanding, since _______________.

Cities are frequently several degrees warmer than the surrounding countryside, a phenomenon known 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, preventing urban areas from cooling down. Furthermore, the scarcity of vegetation in densely built areas removes a natural cooling mechanism, since plants lower temperatures by evaporating water from their leaves. To address this problem, urban planners _______________. One widely used solution involves reflective "cool" roofing engineered to reflect more sunlight than dark rooftops absorb. Another strategy, green infrastructure, incorporates rooftop gardens and tree-lined streets that provide shade while releasing moisture. In contrast, some cities have pursued permeable pavements that let water seep through and evaporate, cooling nearby surfaces. Collectively, these strategies show that reducing urban heat depends on combining approaches suited to a city's geography.

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 unlimited and disposal as if costless. (A) Because such practices lessen dependence on finite raw materials, they reduce the environmental damage caused by mining. Consequently, the circular economy is increasingly regarded as a viable economic strategy that conserves resources for future generations. (B) A circular economy proposes an alternative framework in which materials are kept in continuous use through reuse, repair, and recycling, thereby reducing 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. (C) 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.

Suppose a mysterious being with a near-perfect track record of predicting human choices presents a player with two boxes. (A) The player may choose to take only Box B, or to take both boxes, and the prediction has already been made and cannot change. (B) Box A always contains a visible thousand dollars, while Box B contains either a million dollars or nothing at all, depending on a prediction the being made before the game even began. (C) One line of reasoning says taking both boxes is strictly better, since whatever is already inside the boxes cannot be altered by the player's choice at this point, while a second line of reasoning says taking only Box B is better, given the being's near-perfect accuracy.

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 assessments are grounded in the principle that potential harm should be identified before a project begins, rather than addressed only after damage has already occurred. Before a large-scale construction project such as a highway or dam receives government approval, planners in many countries are required to conduct an environmental impact assessment, a formal process designed to predict and evaluate the ecological consequences of a proposed development. ① This process begins with a baseline survey, in which specialists document existing conditions, including wildlife, water quality, and air composition, so that future changes can be measured against a reference point. ② Analysts then model how the project might alter these conditions, drawing on data from comparable developments. ③ For instance, a proposed highway that would bisect a forest might be evaluated for its potential to fragment habitats, disrupting migration routes on which certain species depend. ④ If the assessment identifies unacceptable risks, planners may be required to redesign the project or adopt mitigation measures such as wildlife corridors. ⑤ Critics contend, however, that assessments are sometimes treated as a bureaucratic formality rather than a genuine constraint, since developers who commission the studies retain strong influence over how the findings are interpreted. ① ② ③ ④ ⑤

If moral responsibility is supposed to depend only on what a person chooses and intends, this outcome seems deeply unfair. Two drivers, equally distracted by their phones, run a red light in exactly the same careless manner. ( ① ) By pure chance, a child happens to be crossing the street in front of one driver but not the other; the first driver kills the child, while the second driver drives through safely and never even notices the danger. ( ② ) Although both drivers behaved identically and made exactly the same reckless choice, society judges them very differently: one faces criminal charges and lifelong guilt, while the other receives, at most, a minor traffic ticket. ( ③ ) Philosophers call this troubling asymmetry moral luck, since factors entirely outside a person's control end up determining how severely we judge their moral character. ( ④ ) Yet few people are willing to excuse the unlucky driver as if nothing worse had happened. ( ⑤ ) Moral luck suggests that our everyday judgments rest on a foundation far shakier than we usually like to admit.
