Emissions trading, a market-based mechanism for ①curbing greenhouse gases, allows governments to set an overall limit on carbon output while letting firms trade permits within that limit. Under this system, ②known as cap-and-trade, companies that cut emissions more cheaply than required can sell surplus allowances to firms facing higher reduction costs. Proponents argue that this flexibility lets society reach a given environmental target at the lowest overall cost, since abatement shifts toward whoever can ③achieve it most economically. Critics, however, ④contends that trading schemes frequently allocate too many permits, a flaw that has historically depressed carbon prices and blunted incentives to invest in cleaner technology. For example, early phases of several regional markets granted allowances so generously that permit prices collapsed, ⑤leaving polluters with little pressure to change their practices.

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

As solar and wind power expand ①rapidly across national grids, engineers face a challenge that receives far less public attention than the construction of the generating facilities themselves. Unlike conventional power plants, which can adjust their output to match demand at almost any moment, solar panels and wind turbines generate electricity only when sunlight or wind is available, producing supply that fluctuates ②rarely. One proposed solution involves large-scale battery storage systems, which absorb ③surplus electricity generated during periods of high output and release it later when generation declines. Another approach relies on expanding transmission networks across wider regions, so that electricity generated in a sunny area can be redirected to places experiencing a ④shortfall. Without such investment, integrating renewable energy could ⑤paradoxically undermine the very reliability that modern electricity grids are expected to provide.

Cities are frequently several degrees ①cooler 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 ②scarcity of vegetation in densely built areas removes a natural cooling mechanism, since plants lower temperatures by evaporating water from their leaves. One widely used solution involves reflective "cool" roofing engineered to ③reflect more sunlight than dark rooftops absorb. In contrast, some cities have pursued permeable pavements that let water seep through and evaporate, ④cooling nearby surfaces. Collectively, these strategies show that reducing urban heat depends on ⑤combining 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 circular economy proposes an alternative framework in which _______________, 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. 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 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.

In a classic experiment inspired by Keynes's beauty contest analogy, participants choose a number between zero and one hundred, and the winner is whoever selects the number closest to two-thirds of the average of all guesses submitted. A perfectly rational player, assuming every other participant reasons with unlimited depth, would conclude the equilibrium number is zero. In practice, however, actual guesses rarely converge on zero; most participants stop reasoning after a round or two of imagining what others might guess, producing _______________. This gap between theoretical equilibrium and observed behavior reveals that human reasoning is bounded.

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. (A) 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, though widespread adoption still faces real obstacles, since genetic sequencing remains expensive in many regions. (B) 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. (C) Precision medicine starts from the observation that this variation often traces back to differences buried in each patient's genome, differences that determine how efficiently a body absorbs, breaks down, or responds to a given drug.

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: This principle applies just as powerfully outside the realm of personal finance. People often recognize, in calm reflection, that their future selves will be tempted to abandon a goal they currently value. ( ① ) Rather than relying solely on willpower at the critical moment, they may choose to restrict their own future options in advance, a strategy known as precommitment. ( ② ) By making certain choices costly, inconvenient, or impossible to reverse, individuals can protect a long-term goal from a short-term impulse that has not yet arisen. ( ③ ) A person hoping to save money might lock funds into an account that penalizes early withdrawal, removing the very temptation that would otherwise be difficult to resist. ( ④ ) Similarly, someone determined to finish a project might publicly announce a deadline, transforming private intentions into a commitment that carries social consequences if broken. ( ⑤ ) What unites these examples is a simple insight: because future desires cannot always be trusted, the wisest moment to act may be now, while judgment remains clear and temptation has not yet taken hold.

This detachment, while sometimes criticized as cold or impersonal, also grants urban residents a distinctive freedom: because so few people know or judge them personally, city dwellers can experiment with identities and lifestyles that would invite intense scrutiny in a smaller, more tightly knit community. German sociologist Georg Simmel argued that the psychological experience of city life differs fundamentally from life in small towns, primarily because urban residents are bombarded with a much greater volume of stimuli than the human nervous system evolved to process. ( ① ) To cope with this constant sensory overload, Simmel proposed, city dwellers develop what he called a blasé attitude. ( ② ) This is a protective indifference in which individuals mentally blunt their emotional reaction to the surrounding crowd, treating most encounters with calculated detachment rather than genuine engagement. ( ③ ) Simmel therefore viewed anonymity as a double-edged feature of modern life. ( ④ ) It isolates individuals from deep communal bonds while simultaneously liberating them from the constant surveillance of small-town social life. ( ⑤ )
