Long before humans learned to drill for oil, microorganisms had already mastered the art of ①converting sunlight and carbon dioxide into stored chemical energy. Modern biofuel research borrows this ability, cultivating algae or engineered bacteria in large tanks where they can be ②coaxed into producing oils and sugars that can be refined into fuel usable in existing engines. Unlike crops grown for corn-based ethanol, which compete directly with food production for arable land, many algae strains can ③thrive in shallow ponds, wastewater, or even coastal seawater unsuitable for conventional agriculture. Engineers have also learned to tinker with the metabolic pathways of these organisms, ④boosted oil yield far beyond what any wild strain would naturally produce on its own. Despite this progress, producing biofuel at a cost competitive with fossil fuel remains difficult, since harvesting and processing the organisms consumes a substantial share of the energy the fuel itself will eventually ⑤provide.

Whenever people discuss the future of reading, one debate never ①seem to end: e-books or paper books? Supporters of e-books point out that a single device can hold thousands of titles, which ②makes traveling with a full library incredibly light. Readers can also change the font size, look up a word instantly, and carry their entire collection in one bag. Fans of paper books, however, argue that something important ③is lost on a screen. Many readers say they remember a paper book's plot more clearly, perhaps because they recall where a scene ④appeared on the page. Screens also invite distraction, since a single notification can pull a reader away from the story in seconds. Interestingly, several recent surveys suggest that most young readers do not choose one format forever. Instead, they switch between paper and digital depending on the situation, ⑤treating the debate less as a contest and more as a matter of convenience.

Cognitive psychologists distinguish between two modes by which the mind handles information, a distinction that helps explain why experienced drivers can hold conversations while navigating familiar roads without conscious effort. Automatic processing occurs ①slowly, requires minimal attention, and typically operates outside conscious awareness, allowing multiple automatic tasks to proceed without interfering with one another. Controlled processing, by contrast, unfolds more slowly, demands ②deliberate attention, and can generally handle only one demanding task at a time, since it draws upon a limited pool of cognitive resources that becomes rapidly depleted under competing demands. Skills that once required intense concentration, such as reading or typing, gradually become automatic through ③extensive practice, freeing attentional resources for other purposes. This shift explains why novice drivers find it difficult to talk while merging onto a highway, whereas seasoned drivers manage the same maneuver with ④comparative ease. However, automaticity carries hidden costs, since automatized responses can be triggered ⑤inappropriately by habitual cues even when circumstances have changed, occasionally producing errors that controlled deliberation would have prevented.

When people face a difficult decision, they often weigh how painful it would feel to discover later that a different choice had been better. This anticipation of future regret frequently becomes the dominant factor shaping the final decision. Researchers have found that people feel sharper regret over losses that resulted from taking action than over identical losses that resulted from doing nothing, _______________. Ironically, this strategy of avoiding regret can itself produce outcomes that are later regretted even more deeply than the ones it was originally designed to prevent.

For decades, memory researchers assumed that repetition alone determined how well information would be retained, an assumption that an influential theory proposed by Craik and Lockhart eventually overturned. According to their framework, what matters most is _______________. Shallow processing, which involves attending merely to superficial features such as the shape of letters or the sound of a word, produces memory traces that fade quickly and remain vulnerable to interference. Elaborative processing, by contrast, requires connecting new information to existing knowledge, generating meaningful associations, and analyzing semantic content, thereby producing traces that are considerably more durable. Consequently, a student who merely repeats a definition aloud without considering its implications is less likely to retain it than one who relates the concept to a personal example. This distinction reshaped educational practice, encouraging teachers to design tasks that demand comprehension rather than mechanical repetition, since durable memory depends on the depth, not the frequency, of cognitive engagement.

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

That simple shift in attitude, from comparison to curiosity, was what finally allowed me to enjoy the exhibition. Every spring, our school holds an art exhibition in the main hallway, and this year I finally submitted a painting of my own. ( ① ) For weeks, I compared my work to my classmates' drawings and felt sure that mine was not good enough to hang beside theirs. ( ② ) My art teacher noticed my hesitation and said something I did not expect: an exhibition is not a contest to find the single best picture, but a chance to show how differently people see the same world. ( ③ ) On the morning the paintings went up, I walked past dozens of styles, from careful realistic portraits to messy, colorful abstractions, and none of them looked like mine. ( ④ ) Instead of feeling embarrassed, I found myself curious about why each artist had made certain choices. ( ⑤ ) Standing in that crowded hallway, I finally understood that the exhibition's real purpose was not to rank the paintings, but to let students discover how many different perspectives could exist in a single shared space.

주어진 문장: Such assessments are grounded in the principle that potential harm should be identified before a project begins, rather than addressed only after damage has already occurred. 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. ① 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. ② Analysts then model how the project might alter these conditions, drawing on data from comparable developments. ③ 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. ④ If the assessment identifies unacceptable risks, planners may be required to redesign the project or adopt mitigation measures such as wildlife corridors. ⑤ 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. ① ② ③ ④ ⑤

주어진 문장: As a result, industries adopting these methods often discover that their overall production costs decline over time, even though the initial transition requires investment. Traditional industrial systems have relied on a linear model of production, in which raw materials are extracted, transformed into goods, and eventually discarded as waste. ① This approach treats natural resources as if unlimited and disposal as if costless. ② A circular economy proposes an alternative framework in which materials are kept in continuous use through reuse, repair, and recycling, thereby reducing the extraction of virgin resources. Central to this model is the notion that waste, rather than being an inevitable byproduct, can be redesigned as a resource for another process, much as fallen leaves nourish the trees that shed them. ③ For example, manufacturers design products so that components can be disassembled and reused in new items once their original function ends. Some companies also lease equipment instead of selling it outright, retaining responsibility for refurbishment. ④ Because such practices lessen dependence on finite raw materials, they reduce the environmental damage caused by mining. ⑤ Consequently, the circular economy is increasingly regarded as a viable economic strategy that conserves resources for future generations. ① ② ③ ④ ⑤

주어진 문장: This buying and selling of allowances effectively creates a market price for carbon, one that fluctuates according to how difficult reduction proves across different industries. Emissions trading, a market-based mechanism for curbing greenhouse gases, allows governments to set an overall limit on carbon output while letting firms trade permits within that limit. ① Under this system, known as cap-and-trade, companies that cut emissions more cheaply than required can sell surplus allowances to firms facing higher reduction costs. ② Proponents argue that this flexibility lets society reach a given environmental target at the lowest overall cost, since abatement shifts toward whoever can achieve it most economically. ③ Critics, however, contend that trading schemes frequently allocate too many permits, a flaw that has historically depressed carbon prices and blunted incentives to invest in cleaner technology. ④ For example, early phases of several regional markets granted allowances so generously that permit prices collapsed, leaving polluters with little pressure to change their practices. ⑤ Consequently, many economists now advocate combining trading with a price floor, a minimum permit price that keeps the market from collapsing during weak demand, thereby preserving the cost-effectiveness for which trading is valued. ① ② ③ ④ ⑤
