Classical economic theory assumes that consumers ①evaluate 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 ②shift in a way that ordinary discounting cannot explain. In a well-known laboratory experiment, participants chose between two chocolates, one of higher quality ③priced at a small fee and one of lower quality offered for free. When both prices were merely ④reduced 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 ⑤changed.

Blockchain technology was originally promoted as a way ①to remove the need for trusted middlemen, allowing strangers to exchange value directly and verify transactions through a shared, tamper-resistant ledger rather than through a bank or government agency. In theory, this design ②distributes power away from any single institution and toward the network as a whole. In practice, however, a small number of large players have come to dominate many blockchain networks, ③controlled enough computing power or currency to influence outcomes that were supposed to be decided collectively. Critics note a further irony: when something goes wrong, there is often no institution left ④to appeal to, since the entire system was designed precisely to eliminate that kind of central authority. Whether decentralization can survive this concentration of power ⑤remains one of the technology's most unresolved questions.

Military researchers have developed weapons systems ①capable of identifying and engaging targets without a human pressing the final button, a prospect that has ②alarmed arms control experts for over a decade. Advocates within defense agencies argue that autonomous systems can react faster than any human operator and may even reduce casualties by removing fear and fatigue from split-second decisions. Human rights organizations counter that removing a person from the final decision ③strip away moral responsibility at the exact moment it matters most, since a machine cannot be held accountable in any meaningful sense. Diplomatic negotiations toward an international treaty have repeatedly ④stalled, partly because military powers disagree on how to define autonomy precisely enough to regulate it. Meanwhile, the underlying technology continues to advance regardless of ⑤whether the diplomacy meant to govern it keeps pace.

When engineers design the software that controls a self-driving car, they inevitably face a question that philosophers have debated for ①decades. If a crash becomes unavoidable, should the vehicle protect its own passenger at all costs, or should it be programmed to ②minimize total harm, even if that means steering toward the person inside? Surveys reveal an uncomfortable ③contradiction: most people say a car should be programmed to save the greater number of lives, yet the same people admit they would never buy a vehicle designed to sacrifice its own owner. This gap between the ideal and the personal choice suggests that ethical programming cannot be settled by public opinion alone. Manufacturers, regulators, and philosophers must instead agree on ④transparent rules before autonomous vehicles are ⑤forbidden to make such decisions on the road.

Sensors buried in the soil now report moisture levels in real time, and automated systems adjust irrigation without a farmer ever walking the rows. For large operations with the capital to invest, these tools have measurably increased yields while reducing water waste. Smaller family farms, however, often cannot afford the upfront cost of this equipment, and some worry that _______________.

Devices that translate brain activity directly into digital commands have moved from laboratory experiments to real medical use, allowing paralyzed patients to control a robotic arm using thought alone. (A) This prospect raises a philosophical question that medicine alone cannot answer: at what point does the assistance stop being a tool and start reshaping the identity of the person using it? (B) As the technology improves, some developers envision a future in which these interfaces extend beyond restoring lost function toward enhancing healthy minds. (C) Neuroethicists argue that mental privacy may need to be recognized as a fundamental right before this technology becomes widespread.

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

This finding is particularly striking given that the two groups of employees faced no difference whatsoever in the financial terms of the plan itself. Employers have long experimented with how retirement savings plans are presented to new hires. ( ① ) In one common arrangement, employees receive a form and must actively check a box to begin contributing a portion of their salary to a savings account. ( ② ) Under this opt-in arrangement, a substantial share of eligible employees never get around to enrolling, often citing simple procrastination rather than genuine disinterest in saving. ( ③ ) When employers instead enroll employees automatically and require them to check a box only if they wish to withdraw, participation rates climb to well over ninety percent. ( ④ ) Only the framing of the choice, not its economic substance, appears to determine whether employees end up saving for retirement. ( ⑤ ) This gap between the two arrangements reveals just how powerfully a default setting can shape decisions that people generally regard as carefully considered.

주어진 문장: This asymmetry alone can be enough to prevent an otherwise reasonable deal from ever being reached. Picture a woman who receives a plain ceramic mug as a free gift at a conference and, later that afternoon, refuses to sell it for anything less than triple its price in the gift shop downstairs. ( ① ) Before she owned the mug, she would never have paid extra for it; once it became hers, however, its value in her mind rose sharply, simply because she now possessed it. ( ② ) Researchers have repeatedly observed this pattern across many everyday objects, from coffee mugs and concert tickets to office chairs and old furniture inherited from relatives. ( ③ ) Owners consistently demand more money to give something up than buyers are willing to offer for that very same item, revealing a curious asymmetry rooted purely in possession itself. ( ④ ) Some economists argue that this effect explains why negotiations over inherited property so often collapse, since each side quietly attaches a different value to what it currently holds. ( ⑤ ) Understanding this bias, therefore, helps explain why simply owning something, even briefly, can distort how fairly people judge its true worth.

주어진 문장: This effect has been demonstrated so consistently across age groups and subject areas that few findings in cognitive psychology are considered more reliable. Dual coding theory, first proposed to explain why certain kinds of information are remembered more readily than others, holds that the mind processes verbal and visual material through two partially independent channels rather than a single unified system. ( ① ) According to this account, words and other linguistic symbols are encoded primarily through a verbal channel that represents meaning in an abstract, sequential form, while pictures and concrete objects are encoded through an imagery channel that preserves spatial and perceptual detail. ( ② ) When information engages both channels simultaneously, as when a textbook pairs a written explanation with an accompanying diagram, the resulting memory trace benefits from two separate, mutually reinforcing pathways of retrieval rather than just one. ( ③ ) This redundancy explains the well-documented picture superiority effect, whereby concrete, easily visualized words tend to be recalled more accurately than abstract terms that resist mental imagery. ( ④ ) Consequently, dual coding theory has profound implications for instructional design, suggesting that combining carefully chosen visuals with concise verbal explanations can strengthen students' long-term retention of complex material.
