The ecological footprint, a widely cited measure of how much biologically productive land and water a population ①require to sustain its consumption, has become one of the most familiar tools for communicating humanity's environmental impact. By ②converting diverse activities, from driving to eating meat, into a single unit of land area, the measure allows policymakers to grasp whether a lifestyle exceeds what the planet can regenerate. This simplicity, however, is also the source of its most persistent criticism. Because the footprint aggregates dissimilar impacts, such as carbon emissions and water scarcity, into one composite figure, it can obscure important differences among problems ③that require distinct policy responses. A region might reduce its footprint by lowering carbon emissions while simultaneously ④depleting a local aquifer, yet the aggregate number could still appear to improve, concealing damage that demands urgent attention. Furthermore, the method assumes that all bio-productive land is roughly interchangeable, ⑤treating a hectare of forest as equivalent to a hectare of farmland, even though the two provide markedly different ecological functions.

Many students imagine a librarian simply ① sit behind a desk and stamping books. Ms. Han, who has worked at a school library for over ten years, says that image is far from accurate. A large part of her job ② involves choosing which new books to buy, based on both student requests and current trends in youth literature. She also spends hours training students to search databases and judge whether an online source ③ is trustworthy, a skill she considers just as important as reading itself. According to Ms. Han, the most rewarding moment is not organizing shelves but watching a student who once avoided reading finally ask for a second book in the same series. She admits that budgets are often tight and that new technology keeps ④ changing how libraries operate. Still, she insists that the core purpose of her job has never ⑤ changed.

When people estimate the value of an unfamiliar product, they rarely rely on objective calculation alone; instead, they anchor their judgment to whatever numerical reference happens to be presented first, however ①arbitrary that number may be. This phenomenon exerts a ②disproportionate influence on price perception precisely because initial figures function as a kind of cognitive gravity that subsequent estimates struggle to escape. A shopper who first sees a jacket listed at $300 before it is marked down to $150 will likely judge the discounted price as an excellent ③bargain, regardless of whether $150 actually reflects the jacket's true worth. Retailers, well aware of this bias, frequently display a ④deflated "original price" beside a discounted one, not because the higher figure is meaningful, but because it recalibrates customers' expectations. Even professionals are not immune: negotiators who open with an extreme initial offer often secure more ⑤favorable final terms than those who begin with a moderate one.

Identical information can provoke strikingly different reactions depending on how it is worded, a phenomenon economists call the framing effect. Patients told that a surgical procedure carries a ninety percent survival rate tend to consent to it far more readily than patients told that the same procedure carries a ten percent mortality rate, even though the two descriptions convey exactly the same statistical reality. Recognizing how deeply framing shapes judgment is therefore essential, not because the underlying facts change, but because the very same facts, dressed in different language, can lead reasonable people toward ___________ conclusions.

Before a large-scale construction project such as a highway or dam receives government approval, planners in many countries are required to conduct an environmental impact assessment, a formal process designed to predict and evaluate the ecological consequences of a proposed development. (A) For instance, a proposed highway that would bisect a forest might be evaluated for its potential to fragment habitats, disrupting migration routes on which certain species depend. If the assessment identifies unacceptable risks, planners may be required to redesign the project or adopt mitigation measures such as wildlife corridors. (B) Critics contend, however, that assessments are sometimes treated as a bureaucratic formality rather than a genuine constraint, since developers who commission the studies retain strong influence over how the findings are interpreted. (C) This process begins with a baseline survey, in which specialists document existing conditions, including wildlife, water quality, and air composition, so that future changes can be measured against a reference point. Analysts then model how the project might alter these conditions, drawing on data from comparable developments.

As buildings account for a substantial share of global energy consumption, architects have increasingly turned to a design philosophy known as the passive house standard, which minimizes energy demand through the building's own structure rather than through mechanical systems. (A) Consequently, many architects regard passive house design not as a luxury for wealthy homeowners but as a practical model capable of reshaping mainstream construction. (B) Central to this approach is airtight construction, in which continuous insulation and sealed joints prevent conditioned air from leaking outward, thereby reducing the heating and cooling loads conventional buildings require. Triple-glazed windows, oriented to capture sunlight in winter while shading interiors in summer, further stabilize indoor temperatures without relying heavily on furnaces or air conditioners. (C) Ventilation systems equipped with heat exchangers also recover warmth from outgoing air, transferring it to incoming air so that comfort is maintained without excessive energy use. For example, some passive houses built in cold climates have reduced heating costs by more than ninety percent.

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.

주어진 문장: Two competing technologies have historically vied for dominance in this field: thermal distillation, which relies on evaporation, and membrane-based filtration, which separates salt without boiling the water. Desalination, the process of removing dissolved salts from seawater to produce fresh water, has increasingly been adopted by coastal regions facing chronic water scarcity. ① 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. ② Because this method consumes far less energy than the thermal distillation once dominant in the industry, it has become the preferred choice for large-scale plants. ③ Nevertheless, desalination remains an inherently costly and environmentally burdensome solution, a fact often overlooked amid enthusiasm for ending water shortages. ④ For instance, the process generates a concentrated byproduct called brine, which, when discharged without adequate dilution, can raise local salinity to levels that harm marine life. ⑤ Pumping seawater through membranes at high pressure also demands substantial electricity, so plants powered by fossil fuels can worsen 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 broader conservation strategy. ① ② ③ ④ ⑤

주어진 문장: This single mistake meant that workers had to sort the entire pile again by hand. Last Saturday, Jimin visited the recycling center near her apartment with her science class. ① She had expected the place to be dirty and unpleasant, but the center looked clean and well organized. ② A worker named Mr. Park guided the students through each area, explaining how bottles, cans, and paper were sorted. He showed them a machine that crushed plastic bottles into small pieces before they were sent to factories. ③ Jimin was surprised to learn that mixed trash, thrown into the wrong bin, often ruined an entire batch of recyclables. For example, one greasy pizza box could contaminate a whole pile of clean paper. ④ However, when items were sorted correctly, they could be reused many times, almost like ingredients in a favorite recipe. Walking home, Jimin realized that her small effort at home truly mattered. ⑤ She decided to sort her family's trash more carefully.

This wasted electricity, though invisible, still comes from real power plants that burn fuel. Turning off lights when you leave a room seems like a tiny action, but it saves more energy than most people expect. ① Every light left on in an empty room wastes electricity that could have powered something useful elsewhere. ② For example, a single classroom light left on overnight can waste enough energy to charge dozens of phones. This habit is similar to leaving a faucet running while you brush your teeth, where water flows out for no reason. ③ Both actions seem harmless in the moment, but they add up to a serious waste over time. Some students argue that a single light does not make much difference. ④ However, when an entire school forms this habit together, the total amount of saved energy becomes significant. ⑤ Therefore, this small daily habit can create a surprisingly large positive effect for the whole planet.
