As solar and wind power expand ①rapidly across national grids, engineers face a challenge that receives 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, producing supply that fluctuates ②rarely. One proposed solution involves large-scale battery storage systems, which absorb ③surplus electricity generated during periods of high output and release it later when generation declines. Another approach relies on expanding transmission networks across wider regions, so that electricity generated in a sunny area can be redirected to places experiencing a ④shortfall. Without such investment, integrating renewable energy could ⑤paradoxically undermine the very reliability that modern electricity grids are expected to provide.

Sociologist William Ogburn observed that when a society undergoes technological change, its material culture tends to advance faster than its nonmaterial culture, meaning norms, laws, and values. He termed the resulting gap cultural lag. The rise of the automobile, for instance, transformed daily mobility long before traffic laws, insurance systems, and urban planning fully adapted to the risks it introduced. A contemporary example can be found in genetic testing, which now allows individuals to learn detailed information about inherited disease risk well before _______________. Cultural lag theory reminds us that technological progress is not automatically matched by social progress.

Metacognition, broadly defined as the capacity to monitor and evaluate one's own cognitive processes, is often treated as a reliable guide to what we actually know, yet a growing body of evidence suggests that the correspondence between subjective confidence and objective accuracy is far weaker than intuition would suggest. Individuals routinely overestimate how thoroughly they have understood a passage of text immediately after reading it, a phenomenon partly attributable to the fluency with which the material was processed rather than to any genuine grasp of its underlying structure. Because rereading familiar material tends to feel effortless, _______________, a misattribution that can lead them to abandon further study prematurely. This gap between perceived and actual mastery, sometimes labeled the illusion of knowing, has practical consequences for education, since students who trust their inflated self-assessments are less likely to seek out the more effortful, retrieval-based strategies that would otherwise consolidate their learning.

Conventional industrial zones typically operate as isolated facilities, each purchasing raw materials independently and disposing of waste without regard for neighboring plants, even when one factory's discarded byproduct could serve as valuable input for another. (A) An eco-industrial park reorganizes this arrangement by clustering diverse companies within a single area and encouraging them to exchange materials, energy, and water through a practice known as industrial symbiosis. A power plant's surplus heat, for example, might be piped to a nearby greenhouse, while a food processing facility's organic waste could be converted into biogas that powers another factory's equipment. (B) Such exchanges require companies to coordinate schedules and share information they might otherwise regard as proprietary, a level of cooperation rarely achieved without deliberate institutional support. Local governments therefore often play a coordinating role, mapping which industries could exchange resources and providing incentives for companies willing to participate. (C) Consequently, eco-industrial parks have come to be seen as a model capable of reducing both waste disposal costs and raw material expenses simultaneously.

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. (A) 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, though widespread adoption still faces real obstacles, since genetic sequencing remains expensive in many regions. (B) 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. (C) Precision medicine starts from the observation that this variation often traces back to differences buried in each patient's genome, differences that determine how efficiently a body absorbs, breaks down, or responds to a given drug.

When a country physician named Edward Jenner noticed that milkmaids who had caught cowpox seemed immune to smallpox, he set in motion a medical revolution without fully understanding why it worked. (A) This method produced genuine successes, eventually eliminating smallpox worldwide and reducing diseases such as polio and measles, but each new vaccine still required years of laboratory work with no guarantee of success. (B) Advances in molecular biology eventually allowed researchers to isolate a single protein from a pathogen's surface, producing vaccines with fewer side effects, and the most recent shift toward delivering genetic instructions represents the latest chapter in this story. (C) For nearly two centuries afterward, vaccine development proceeded largely by trial and error, weakening or killing a pathogen and testing whether the resulting preparation could train the immune system without causing disease itself.

A small bakery once sold a basic loaf of bread for three dollars and a premium loaf for six dollars, and most customers, uncertain about the added value of the pricier option, simply bought the cheaper one. (A) Almost nobody chose this new seven-dollar loaf, yet sales of the six-dollar loaf rose sharply, because it now appeared to be an obvious bargain beside the inferior newcomer. (B) This pattern, confirmed across countless pricing experiments in other markets, demonstrates that people rarely judge options in isolation but instead evaluate them relative to whatever alternatives happen to be nearby. (C) The owner then introduced a third option: a slightly larger premium loaf priced at seven dollars, one that was clearly inferior to the six-dollar loaf in terms of value for money.

주어진 문장: This question has motivated economists to search for empirical patterns linking national income levels to measurable indicators of environmental quality. Economists have long debated whether prosperity and environmental quality are fundamentally opposed, or whether the relationship between them changes shape as an economy matures. ① The Environmental Kuznets Curve, a hypothesis borrowed from earlier theories of income inequality, proposes that pollution initially rises alongside economic growth before eventually declining once a society crosses a certain threshold of wealth. ② In its early stages, industrializing nations prioritize output over conservation, treating clean air and water as expendable costs of development to be addressed later. ③ Beyond a certain point, however, rising incomes generate both the technological capacity and the political will to demand stricter regulation, so degradation begins to reverse even as production keeps expanding. ④ Some scholars regard this trajectory as a reassuring paradox, suggesting that the very growth blamed for ecological harm may eventually finance its own repair. ⑤ Critics, by contrast, argue that the curve rests on a narrow selection of pollutants that happen to decline with wealth, while ignoring greenhouse gases and resource depletion, which show no comparable tendency to fall. ① ② ③ ④ ⑤

Suppose a traveler journeyed backward in time and, through some combination of accident and intention, prevented their own grandfather from ever meeting their grandmother. Time travel to the past has long fascinated physicists and philosophers alike, but it also generates a famously troubling contradiction. ( ① ) If the grandfather never had children, the traveler themselves would never have been born, which means the traveler could never have existed to make the trip in the first place. ( ② ) Yet if the traveler never made the trip, the grandfather would have survived to meet the grandmother after all, allowing the traveler to be born and eventually travel back in time. ( ③ ) The story therefore loops endlessly, undermining itself at every turn rather than settling into any stable outcome. ( ④ ) Some physicists resolve the paradox by arguing that any consistent timeline must forbid such self-defeating actions from ever succeeding. ( ⑤ ) Others propose that a traveler who alters the past simply branches off into a separate, parallel timeline instead.

For this reason, many economists argue that the real challenge is not the robots themselves, but the speed at which society is expected to adapt to them. 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. ( ① ) Economists have long debated whether this shift destroys jobs or simply transforms them. ( ② ) Historical evidence offers some comfort: previous waves of automation eventually created new categories of work that no one had predicted. ( ③ ) However, critics point out that earlier transitions unfolded over generations, giving workers time to retrain, whereas today's robots are being deployed at a pace that leaves little room for adjustment. ( ④ ) A factory worker displaced this year cannot simply wait for a new industry to emerge decades from now. ( ⑤ )
