Long before humans learned to drill for oil, microorganisms had already mastered the art of ①converting sunlight and carbon dioxide into stored chemical energy. Modern biofuel research borrows this ability, cultivating algae or engineered bacteria in large tanks where they can be ②coaxed into producing oils and sugars that can be refined into fuel usable in existing engines. Unlike crops grown for corn-based ethanol, which compete directly with food production for arable land, many algae strains can ③thrive in shallow ponds, wastewater, or even coastal seawater unsuitable for conventional agriculture. Engineers have also learned to tinker with the metabolic pathways of these organisms, ④boosted oil yield far beyond what any wild strain would naturally produce on its own. Despite this progress, producing biofuel at a cost competitive with fossil fuel remains difficult, since harvesting and processing the organisms consumes a substantial share of the energy the fuel itself will eventually ⑤provide.

Classical economic theory long assumed that decision makers ①gather all relevant information, calculate every possible outcome, and select the single option that maximizes their benefit. Herbert Simon, however, questioned this assumption, ②arguing that human beings operate under real constraints of time, knowledge, and mental capacity that make such exhaustive calculation practically impossible. Instead of searching endlessly for the theoretically perfect choice, people typically stop once they find an option that seems good enough to meet their immediate needs, a strategy Simon ③termed satisficing. A shopper comparing refrigerators, for example, rarely examines every model available; she instead sets a few practical criteria, such as price and size, and selects the first appliance that satisfies them adequately. This approach is not a failure of reasoning but rather a sensible adaptation to a world where information is costly and time is genuinely limited. Consequently, models assuming unlimited rationality often fail to predict actual behavior, while frameworks ④acknowledge these cognitive boundaries offer a far more realistic account of how ordinary decisions are ⑤made.

Factories that once employed hundreds of workers on an assembly line now run with a fraction of that staff, as robotic arms handle tasks ①that used to require human hands. Economists have long debated whether this shift destroys jobs or simply ②transforms them. Historical evidence offers some comfort: previous waves of automation eventually created new categories of work that no one ③had predicted. However, critics point out that earlier transitions unfolded over generations, ④given workers time to retrain, whereas today's robots are being deployed at a pace that leaves little room for adjustment. For this reason, many economists argue that the real challenge is not the robots themselves, but the speed at which society ⑤is expected to adapt to them.

Rewilding, a conservation strategy that seeks to restore natural processes with minimal human interference, has gained attention as traditional conservation struggles to halt biodiversity loss. Rather than managing landscapes according to a ①fixed blueprint, rewilding projects often reintroduce key species, such as large predators, whose presence can trigger cascading effects. Advocates point to the reintroduction of wolves in certain parks, where predation altered grazing behavior, allowing riverside vegetation to ②decline and stabilizing soil that had long been eroding. Skeptics, however, warn that rewilding can provoke ③serious conflict with nearby communities, particularly when predators prey on livestock or restored habitats limit land for agriculture. Moreover, critics argue that restoring landscapes to an imagined pristine state is scientifically ④dubious, since ecosystems have long been shaped by human activity. Compensation programs reimbursing farmers for livestock losses, alongside ecotourism initiatives creating local income, have proven ⑤essential to sustaining public support.

People often recognize, in ①calm reflection, that their future selves will be tempted to abandon a goal they currently value. 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. By making certain choices ②affordable, inconvenient, or impossible to reverse, individuals can protect a long-term goal from a short-term impulse that has not yet arisen. A person hoping to save money might lock funds into an account that ③penalizes early withdrawal, removing the very temptation that would otherwise be difficult to resist. Similarly, someone determined to finish a project might ④publicly announce a deadline, transforming private intentions into a commitment that carries social consequences if broken. What unites these examples is a simple insight: because future desires cannot always be ⑤trusted, the wisest moment to act may be now.

Émile Durkheim insisted that sociology could become a genuine science only if it identified a ①distinct subject matter that could not be reduced to individual psychology. He termed this subject matter social facts, defined as ways of thinking, feeling, and acting that exist outside any single individual yet exert a ②coercive influence over that individual's behavior. Language, currency, legal codes, and religious ritual all qualify as social facts, since a person is born into these systems already fully formed and must ③conform to them regardless of personal preference. Durkheim insisted that social facts should be studied as things, meaning they must be examined ④empirically through observable patterns such as statistics. His study of suicide rates exemplified this method, showing that rates varied ⑤randomly according to variables such as religious affiliation and marital status, patterns that could not be explained by individual psychology alone.

Classical economic theory assumes that consumers evaluate every price change in the same rational way, weighing marginal benefit against marginal cost regardless of the absolute numbers involved. Behavioral economists, however, have discovered a striking exception: the moment a price drops to exactly zero, people's judgment shifts in a way that ordinary discounting cannot explain. In a well-known laboratory experiment, participants chose between two chocolates, one of higher quality priced at a small fee and one of lower quality offered for free. When both prices were merely reduced by the same amount, most participants still preferred the higher-quality option. Yet once the cheaper chocolate's price was lowered to zero, the majority abruptly switched their preference, even though the price gap between the two options had not actually changed. Researchers explain this reversal by noting that _______________.

주어진 문장: In other words, a single aggregate score cannot reveal which specific resource is actually under strain. 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. ① This simplicity, however, is also the source of its most persistent criticism. ② 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. ③ 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. ④ 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. ⑤ ① ② ③ ④ ⑤

주어진 문장: This buying and selling of allowances effectively creates a market price for carbon, one that fluctuates according to how difficult reduction proves across different industries. Emissions trading, a market-based mechanism for curbing greenhouse gases, allows governments to set an overall limit on carbon output while letting firms trade permits within that limit. ① Under this system, known as cap-and-trade, companies that cut emissions more cheaply than required can sell surplus allowances to firms facing higher reduction costs. ② Proponents argue that this flexibility lets society reach a given environmental target at the lowest overall cost, since abatement shifts toward whoever can achieve it most economically. ③ Critics, however, contend that trading schemes frequently allocate too many permits, a flaw that has historically depressed carbon prices and blunted incentives to invest in cleaner technology. ④ For example, early phases of several regional markets granted allowances so generously that permit prices collapsed, leaving polluters with little pressure to change their practices. ⑤ Consequently, many economists now advocate combining trading with a price floor, a minimum permit price that keeps the market from collapsing during weak demand, thereby preserving the cost-effectiveness for which trading is valued. ① ② ③ ④ ⑤

Durkheim called this state of normlessness anomie, arguing that rapid social change can strip away the moral guidelines that regulate human desire, leaving individuals disoriented even when material conditions improve. When sociologist Émile Durkheim studied suicide rates across different societies, he noticed something puzzling: rates rose not only during economic depression but also during sudden prosperity. ( ① ) He concluded that both crises share a common feature, the collapse of shared norms that once told individuals what to expect and how to behave. ( ② ) Decades later, Robert Merton extended the concept to explain deviance within stable societies. ( ③ ) He proposed that anomie also arises when a culture insists that everyone pursue identical goals, such as wealth, while denying many people the legitimate means to achieve them. ( ④ ) Faced with this gap between aspiration and opportunity, some individuals conform, but others turn to innovation, ritual, retreat, or rebellion. ( ⑤ ) Anomie theory therefore suggests that crime is less a product of individual failure than of structural imbalance within society itself.
