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.

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.

When people encounter an individual who appears to memorize enormous quantities of specialized information ①effortlessly, they often assume that person possesses an innate gift. Cognitive psychologists, however, contend that such feats ②rarely stem from raw talent alone. Instead, such feats arise from a learned skill known as chunking, whereby scattered pieces of information are consolidated into larger, meaningful units. A landmark study of chess players demonstrated this principle. When shown a board arranged according to plausible game positions, grandmasters reproduced the layout perfectly. Yet when the same pieces were scattered randomly, their performance ③collapsed to the level of novices. This pattern reveals that expert memory is not larger in raw capacity but is instead organized around patterns accumulated through years of deliberate practice. If chunking, rather than innate aptitude, ④contradicts expert performance, then educators should stop treating talent as fixed and destiny-bound. Curricula ought to be redesigned to cultivate pattern recognition explicitly, since doing so would grant far more students access to expertise once ⑤presumed reserved for the naturally gifted.

As private companies develop the technology to mine asteroids for rare metals and water, a legal question once confined to science fiction has suddenly become ①urgent: who, if anyone, owns the resources of outer space? Existing international treaties state that no nation may claim sovereignty over celestial bodies, but they say remarkably ②little about whether a private company may extract and sell what it finds there. Some governments have already passed domestic laws granting their own companies rights to material mined in space, a move that other nations view as a ③collective attempt to settle a question that should be decided collectively. Supporters of space mining argue that new resources could ④ease shortages on Earth and fund further exploration, while critics ⑤warn that treating space as an open frontier for extraction risks repeating the same mistakes that colonization caused on Earth.

A rational approach to decision-making dictates that only future costs and benefits should influence a choice, since resources already spent cannot be recovered regardless of what is decided next. In practice, however, people routinely allow such irrecoverable expenditures, known as sunk costs, to shape their subsequent decisions, a pattern referred to as the sunk cost fallacy. Economists therefore urge decision-makers to evaluate each choice based solely on its prospective outcomes, treating past expenditures as ___________ to the decision at hand.

As efforts to curb greenhouse gas emissions intensify, industries unable to eliminate carbon dioxide from their processes have turned to a technology known as carbon capture and storage. This technology involves separating carbon dioxide from the exhaust of power plants before it is released into the atmosphere, then transporting the captured gas for underground injection. Once injected into porous rock formations, the gas is trapped beneath layers of impermeable rock that prevent it from escaping into the air. Proponents argue that carbon capture and storage _______________. For instance, cement and steel production, both of which release carbon dioxide as an unavoidable byproduct of chemical reactions, are considered prime candidates for this approach. However, critics contend that the technology remains prohibitively expensive and that building pipelines requires investments few companies make voluntarily. Despite such concerns, many governments continue funding pilot projects, convinced that this technology will play an indispensable role in reaching emission targets.

Many households save far less for retirement than conventional financial advice would recommend. Some economists have proposed a savings program in which employees commit today to allocating a portion of their future salary increases toward retirement savings, rather than being asked to reduce their current take-home pay immediately. Field trials of such programs have reported substantial increases in average savings rates. This approach demonstrates that savings policy grounded in realistic assumptions about human psychology can prove considerably more ___________ than policy grounded in the assumption that individuals will always act in strict accordance with their own long-term rational interests.

Mental accounting also shapes how consumers respond to windfalls of different sizes and origins. (A) A modest windfall, such as a small cash-back reward, tends to be absorbed into everyday spending and disappears almost unnoticed within a household's general budget. (B) A substantial windfall, by contrast, such as an inheritance or a large bonus, is more likely to be mentally assigned to a separate category, sometimes labeled as "extra" money reserved for investment or a significant purchase. (C) This difference in treatment suggests that the perceived significance of a sum, rather than its objective purchasing power, determines the mental account into which it is placed.

This puzzling inconsistency is not, as it turns out, a matter of chance. 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. ( ① ) Precision medicine starts from the observation that this variation often traces back to differences buried in each patient's genome. ( ② ) These differences determine how efficiently a body absorbs, breaks down, or responds to a given drug. ( ③ ) 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. ( ④ ) 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. ( ⑤ ) Widespread adoption still faces real obstacles, since genetic sequencing remains expensive in many regions and few doctors have been trained to interpret the flood of genetic data such tests now produce.

주어진 문장: This effect was first demonstrated systematically through a series of controlled laboratory experiments conducted in the 1970s. Eyewitness testimony has long carried weight in courtrooms, yet decades of research reveal that memories of witnessed events are more malleable than most people assume. ( ① ) When individuals who observe an event are later exposed to misleading information about what they saw, whether through a leading question or a conversation with another witness, their recollections frequently incorporate details that never occurred, a phenomenon known as the misinformation effect. ( ② ) In one classic paradigm, participants who watched a video of a traffic accident and were then asked how fast the cars were going when they smashed into each other reported higher speed estimates and were more likely to falsely recall broken glass than participants asked the identical question using the milder verb hit. ( ③ ) Crucially, these distorted memories often feel genuine to the person experiencing them, since the original memory trace becomes blended with the newly introduced information rather than existing as a separate, contradictory record. ( ④ ) Such findings have prompted legal systems to adopt cautious interviewing protocols designed to minimize suggestive questioning during investigations. ( ⑤ )
