Suppose a mad scientist removed a living brain from its body, placed it in a vat of nutrient fluid, and connected its neurons to a supercomputer capable of generating perfectly ①unrealistic sensations. The brain would experience a full and convincing world, complete with a sky, a body, and other people, without ever suspecting that none of it existed outside the simulation. This scenario, unsettling as it sounds, raises a genuinely difficult question for anyone confident in their own perception: how could a person ever ②prove that they are not that very brain right now? Ordinary evidence cannot help, since any proof gathered through the senses would itself be ③generated by the same simulation being tested. Some philosophers conclude that absolute certainty about the external world is simply ④unattainable, while others argue that the mere possibility of deception, however vivid, is not sufficient reason to ⑤abandon our everyday trust in what we perceive.

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.

Prospect theory proposes that the subjective value of money is not a straight line but a ①curved function. In the domain of gains, the function bends downward as amounts increase, so the psychological difference between earning zero and one hundred dollars feels far ②greater than between earning one thousand and eleven hundred. A parallel pattern appears among losses, where the curve bends in the ③opposite direction, yet sensitivity still fades as the amount grows larger. This tendency, known as diminishing sensitivity, explains why a shopper ④acutely notices a ten dollar increase on a two thousand dollar purchase, though the same ten dollars would matter enormously as the price of a meal. Researchers illustrate this curvature with graphs shaped like an S turned sideways, ⑤flattening toward both extremes.

Economists have long debated whether prosperity and environmental quality are fundamentally opposed, or whether the relationship between them changes shape as an economy matures. The Environmental Kuznets Curve, a hypothesis borrowed from earlier theories of income inequality, proposes that _______________. In its early stages, industrializing nations prioritize output over conservation, treating 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 to 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 blamed 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.

For much of the twentieth century, memory researchers assumed that once a memory had been consolidated—transformed from a fragile, short-term trace into a stable, long-term representation—it remained essentially fixed, immune to further modification unless the underlying neural circuitry was physically damaged. This assumption, however, was overturned by a body of research demonstrating that _______________, rendering it temporarily susceptible to alteration before it is, in a sense, filed away again. During this narrow window, which typically lasts only a few hours, the memory can be strengthened, weakened, or even subtly distorted by new information encountered in the interim, after which it must undergo a second round of stabilization, a process now widely referred to as reconsolidation. Consequently, what we experience as a stable recollection may actually be a continuously revised construction, reshaped every time it is summoned into conscious awareness and returned to storage.

Behavioral economists have long observed that people tend to feel the pain of losing something more intensely than the pleasure of gaining an equivalent amount, a tendency known as loss aversion. Consider an investor who refuses to sell a declining stock, clinging to the hope that its price will eventually recover, even when all available evidence indicates that selling and reinvesting elsewhere would be more rational. As a result, loss aversion frequently pushes individuals toward ___________ rather than toward the outcome that would maximize their overall welfare.

Retailers have discovered practical ways to counteract the negative effects of choice overload without simply reducing the number of products they offer. (A) One common strategy involves organizing an extensive product catalog into clearly labeled categories and subcategories, allowing customers to narrow their search gradually rather than confronting the entire array at once. (B) Another approach highlights a small number of curated recommendations, such as "staff picks" or "best sellers," giving hesitant customers a reasonable starting point without eliminating other options entirely. (C) Both strategies share a common principle: they do not reduce the objective number of choices available but instead reduce the cognitive burden of navigating them.

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

주어진 문장: As a result, no single boundary can be evaluated in isolation from the others. 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. ① 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. ② 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. ③ 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. ④ 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. ⑤ Critics, however, contend that the boundaries are drawn with more confidence than the data can support. ① ② ③ ④ ⑤

주어진 문장: This danger arises because no single participant possesses both the authority and the incentive needed to restrict others' access to the resource. When a resource is shared among many users, none of whom bears the full cost of its depletion, each individual is tempted to extract as much value as possible before others do the same. ① 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. ② 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. ③ Because self-interest offers no incentive to restrain consumption unilaterally, the resource tends to be exhausted long before any user intends such an outcome. ④ For decades, economists assumed that only two remedies existed: strict regulation or the conversion of shared resources into private property. ⑤ 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. ① ② ③ ④ ⑤
