Biodegradable plastics have been promoted as a promising solution to plastic waste, since they ①are designed to decompose into natural substances rather than persist for centuries. Manufacturers derive these materials from renewable resources such as corn starch, blending them with additives that ②accelerates microbial breakdown once discarded. However, their environmental benefits are often exaggerated, largely because decomposition depends on specific conditions rarely ③found outside industrial composting facilities. For example, a bag labeled biodegradable may take years, not the weeks advertised, to break down in a landfill or ocean, where temperature and microbial activity remain low. In addition, when mixed with conventional plastics in recycling streams, they can contaminate the process, ④weakening the quality of materials produced afterward. Some engineers therefore compare biodegradable plastics to a bridge that leads nowhere unless paired with infrastructure that completes the journey. Ultimately, realizing their genuine potential requires not only technological refinement but also facilities capable of ⑤providing the precise conditions decomposition demands.

Classical economic models typically assume that people discount future rewards at a constant rate, ①valuing a reward received later somewhat less than an identical reward received now. Empirical observation, however, reveals a different pattern: people apply a much steeper discount to the immediate future than to the distant future, a phenomenon ②termed hyperbolic discounting. This inconsistency explains why an individual might sincerely resolve tonight to wake up early and exercise tomorrow, only to postpone the plan once tomorrow actually arrives and the immediate discomfort of getting out of bed ③become vivid and present. When the reward or cost in question lies safely in the future, its emotional weight remains muted, ④allowing rational long-term goals to dominate one's stated intentions. Once that same reward or cost draws near, however, its immediacy triggers a disproportionately strong emotional pull, frequently ⑤overriding the very plans made earlier with such apparent confidence.

Among the many strategies proposed to remove carbon dioxide from the atmosphere, one of the oldest ①draw on an agricultural technique predating modern industry, converting organic material into a stable form of charcoal known as biochar. Biochar is ②produced through pyrolysis, a process in which crop residues or wood chips are heated in an environment with little or no oxygen, ③preventing the material from burning away as in an open fire. 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, ④retaining moisture and nutrients otherwise lost, which can boost crop yields in depleted soils. For example, farmers ⑤cultivating nutrient-poor tropical soils have reported measurable increases in productivity after adding biochar.

For decades, memory researchers assumed that repetition alone determined how well information would be retained, an assumption that an influential theory proposed by Craik and Lockhart eventually overturned. According to their framework, what matters most is not how many times a person rehearses material but how deeply that material is processed during encoding. ①Shallow processing, which involves attending merely to superficial features such as the shape of letters or the sound of a word, produces memory traces that fade quickly and remain ②vulnerable to interference. Elaborative processing, by contrast, requires connecting new information to existing knowledge, generating meaningful associations, and analyzing semantic content, thereby producing traces that are considerably more ③fragile. Consequently, a student who merely repeats a definition aloud without considering its implications is less likely to retain it than one who relates the concept to a personal example. This distinction reshaped educational practice, encouraging teachers to design tasks that demand ④comprehension rather than ⑤mechanical repetition, since durable memory depends on the depth, not the frequency, of cognitive engagement.

Sensors buried in the soil now report moisture levels in real time, drones survey entire fields for signs of disease within minutes, and automated systems adjust irrigation without a farmer ever walking the rows. For large operations with the capital to invest, these tools have ①measurably increased yields while ②reducing water waste, addressing two problems that traditional farming has struggled with for generations. Smaller family farms, however, often ③cannot afford the upfront cost of this equipment, and some worry that the gap between high-tech and traditional operations will only widen as the technology advances further. There is also a quieter cultural cost that rarely appears in productivity reports: generations of farming knowledge risk being ④preserved by dashboards and automated alerts that few young farmers are taught to question, a loss productivity reports rarely ⑤capture.

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

When people face a difficult decision, they often weigh how painful it would feel to discover later that a different choice had been better. This anticipation of future regret frequently becomes the dominant factor shaping the final decision. Researchers have found that people feel sharper regret over losses that resulted from taking action than over identical losses that resulted from doing nothing, _______________. Ironically, this strategy of avoiding regret can itself produce outcomes that are later regretted even more deeply than the ones it was originally designed to prevent.

Labeling theory approaches deviance not as a fixed property of certain acts, but as a social process created when powerful groups attach a negative label to a person's behavior. (A) Once labeled, an individual may find legitimate opportunities closing off, pushing them toward the very community of offenders that the label predicted they would join. (B) According to this view, nearly everyone breaks minor rules at some point, yet only some individuals are singled out and formally branded as delinquents or criminals. (C) This process, sometimes called secondary deviance, illustrates how social reaction can produce the outcome it claims merely to describe.

주어진 문장: Beyond these practical objections, some conservationists raise a more fundamental theoretical concern about what rewilding is ultimately trying to achieve. 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. ① Rather than managing landscapes according to a fixed blueprint, rewilding projects often reintroduce key species, such as large predators, whose presence can trigger cascading effects. ② Advocates point to the reintroduction of wolves in certain parks, where predation altered grazing behavior, allowing riverside vegetation to recover and stabilizing soil that had long been eroding. ③ Skeptics, however, warn that rewilding can provoke serious conflict with nearby communities, particularly when predators prey on livestock or restored habitats limit land for agriculture. ④ Moreover, critics argue that restoring landscapes to an imagined pristine state is scientifically dubious, since ecosystems have long been shaped by human activity. ⑤ Compensation programs reimbursing farmers for livestock losses, alongside ecotourism initiatives creating local income, have proven essential to sustaining public support. Ultimately, rewilding succeeds not by removing human influence but by renegotiating the relationship between people and the wild species they must coexist with. ① ② ③ ④ ⑤

The same mechanism that helps citizens save more for retirement, in other words, can just as easily be turned against their financial interests. Default settings are not inherently virtuous; their ethical value depends entirely on whose interests they serve. ( ① ) A retirement plan that automatically enrolls employees at a reasonable contribution rate generally benefits those employees by overcoming their tendency toward inertia. ( ② ) A subscription service that automatically renews at a higher price unless the customer actively cancels, however, exploits that very same inertia for the company's benefit rather than the customer's. ( ③ ) Both arrangements rely on the identical psychological tendency to accept whatever has been preselected. ( ④ ) Distinguishing between beneficial and exploitative uses of default settings therefore requires examining not the mechanism itself but the intentions and incentives of whoever designed it. ( ⑤ ) Regulators increasingly demand transparency about default settings precisely because the mechanism alone cannot reveal whether it serves the consumer or merely the company offering it.
