As solar and wind power expand rapidly across national grids, engineers face a challenge that ①receive 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, ②producing supply that fluctuates constantly. One proposed solution involves large-scale battery storage systems, ③which absorb surplus electricity generated during periods of high output and release it later when generation declines. Grid operators must therefore invest in infrastructure capable of ④accommodating this variability, rather than assuming renewable sources can simply replace fossil fuels without adjustment. Without such investment, integrating renewable energy could paradoxically undermine the very reliability that modern electricity grids are ⑤expected to provide.

Philosopher Robert Nozick asked his readers to imagine a machine capable of producing any experience they ①desired, from writing a great novel to falling in love, all indistinguishable from reality once they were plugged in. Neuroscientists would simply stimulate the brain to generate a lifetime of perfectly satisfying experiences, and the person floating in the tank would have no memory of ever choosing to enter it. If pleasure and the avoidance of pain were truly all that mattered, as classical hedonism claims, then everyone should ②rush to connect themselves permanently to such a machine. Yet when people actually consider the offer, most ③eagerly accept, and many refuse outright. Nozick took this reluctance as evidence that human beings care about more than the quality of their internal sensations; people also want to actually ④do certain things, to actually be a certain kind of person, and to maintain genuine ⑤contact with a reality beyond their own mind.

A few years ago, spotting a manipulated video required a trained eye and ①specialized software. Today, freely available applications allow almost anyone to swap a face or fabricate a voice ②convincingly enough to fool casual viewers within minutes. This shift has quietly ③reinforced one of the oldest assumptions in human communication: that seeing and hearing something is a reasonably reliable way to confirm it happened. Journalists now face the burden of verifying footage that once would have been accepted as ④self-evident proof. Perhaps more troubling than any single fake video is the broader effect on public trust, in which genuine footage can be ⑤dismissed as fabricated simply because deepfakes exist.

When workers receive a five percent raise in a year when prices have climbed five percent as well, their real purchasing power has not changed at all, yet many still report feeling ①noticeably better off. This tendency to judge economic well-being by ②nominal figures printed on a paycheck, rather than by what that money can actually purchase, is known among economists as money illusion. Employers exploit this pattern by favoring modest nominal raises over deeper structural adjustments, since a visible increase on a payslip ③disappoints employees more effectively than an explanation about inflation could. The illusion persists even among people who claim to understand inflation well, which suggests that the bias operates at an ④intuitive level that formal knowledge does not easily override. Some economists argue that policymakers should exploit this illusion strategically, since workers resist nominal wage cuts far more ⑤fiercely than they resist the equivalent erosion of real wages.

Desalination, the process of removing dissolved salts from seawater to produce fresh water, has increasingly been adopted by coastal regions facing chronic water ①scarcity. Most modern facilities rely on reverse osmosis, a technique in which seawater is forced through membranes whose microscopic pores block salt while letting water molecules pass. Because this method ②consumes far less energy than the thermal distillation once dominant in the industry, it has become the preferred choice for large-scale plants. Nevertheless, desalination remains an inherently costly and environmentally burdensome solution, a fact often overlooked amid enthusiasm for ending water shortages. For instance, the process generates a ③concentrated byproduct called brine, which, when discharged without adequate dilution, can raise local salinity to levels that harm marine life. Pumping seawater through membranes at high pressure also demands substantial electricity, so plants powered by fossil fuels can ④alleviate the emissions that intensify drought. Therefore, engineers increasingly argue that desalination should be treated not as a stand-alone remedy but as one component of a ⑤broader conservation strategy.

Modern consumer culture often assumes that expanding the range of available options will automatically make people freer and happier, yet a growing body of research suggests the opposite may sometimes be true. When individuals select from an enormous set of alternatives, satisfaction with the final choice frequently declines rather than rises, even when the chosen item is objectively excellent. Having considered so many possibilities, a person naturally imagines the specific advantages that a different, unchosen option might have offered, and this imagined comparison quietly erodes contentment with what was actually selected. The paradox, therefore, is that _______________.

Generative AI systems learn to write, draw, and compose by studying enormous collections of existing human work. Supporters argue that this resembles how a human student learns by studying the masters. Critics respond that the comparison breaks down at scale: _______________. Courts around the world are now being asked to decide whether training an algorithm on copyrighted material counts as fair use or as infringement.

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 urgent: who, if anyone, owns the resources of outer space? (A) Some governments have already passed domestic laws granting their own companies rights to material mined in space, a move other nations view as a unilateral attempt to settle a shared question. (B) Existing international treaties state that no nation may claim sovereignty over celestial bodies, but they say remarkably little about whether a private company may extract and sell what it finds there. (C) Supporters of space mining argue that new resources could ease shortages on Earth, while critics warn that treating space as an open frontier for extraction risks repeating past mistakes.

Factories that once employed hundreds of workers on an assembly line now run with a fraction of that staff, as robotic arms handle tasks that used to require human hands. (A) However, critics point out that earlier transitions unfolded over generations, giving workers time to retrain, whereas today's robots are being deployed much faster. (B) Historical evidence offers some comfort: previous waves of automation eventually created new categories of work that no one had predicted. (C) A factory worker displaced this year, therefore, cannot simply wait for a new industry to emerge decades from now.

주어진 문장: Those who had learned the words underwater, for example, performed best when tested underwater again, while those who had studied on land performed best on land. Students are frequently told that where they study makes little difference, provided that they put in enough hours. Cognitive research on memory retrieval, however, suggests that this advice oversimplifies an important process. ( ① ) According to the encoding specificity principle, information becomes intertwined with the context in which it was originally learned. Cues present during encoding therefore facilitate retrieval far more effectively than cues encountered elsewhere. ( ② ) A striking demonstration involved divers who memorized word lists either underwater or on dry land. When tested later, divers recalled substantially more words if the testing environment matched the original learning environment. ( ③ ) This held true regardless of which environment that happened to be. This finding implies that reviewing material exclusively in a quiet bedroom may not adequately prepare a student for the noisy atmosphere of an actual examination hall. ( ④ ) Rather than assuming that memorization is a context-free process, students ought to consider deliberately varying study locations and conditions. ( ⑤ ) Doing so would ensure that retrieval cues remain available regardless of how a future test is administered.
