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 ①designed to predict and evaluate the ecological consequences of a proposed development. This process begins with a baseline survey, in which specialists ②document 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, ③drawn on data from comparable developments. For instance, a proposed highway that would bisect a forest might be evaluated for its potential to fragment habitats, ④disrupting 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. Critics contend, however, that assessments are sometimes treated as a bureaucratic formality rather than a genuine constraint, since developers who ⑤commission the studies retain strong influence over how the findings are interpreted.

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.

Among the many tools available to those who design choice environments, few are as quietly powerful as the default option, the alternative that ①takes effect automatically unless a person actively selects something else. Because changing a default requires deliberate effort, many individuals simply accept whatever arrangement has been preselected for them, regardless of whether that arrangement actually ②serve their interests best. This tendency has been documented across a remarkably wide range of contexts. Countries that automatically enroll citizens in organ donation programs, requiring an explicit request to opt out, consistently report far higher donor registration rates than countries that require citizens ③to actively opt in. Employers who automatically enroll new hires in retirement savings plans likewise see participation rates ④climb dramatically compared with employers who leave enrollment entirely voluntary. What makes default options so influential is not merely convenience; a default also functions as an implicit signal about what is considered normal or recommended, subtly ⑤shaping perceptions even among individuals who believe themselves to be deciding independently.

Psychologists studying human judgment often describe the mind as operating through two distinct systems rather than a single unified process. System 1 works ①quickly and automatically, generating impressions and snap judgments without any noticeable sense of effort. System 2, by contrast, is slow, ②deliberate, and demanding, engaged only when a problem requires careful calculation or conscious reasoning. Most daily decisions are handled almost entirely by System 1, which allows people to function ③efficiently without exhausting their limited mental resources. This efficiency comes at a cost, however, because System 1 relies on simple shortcuts that can produce systematic errors, and System 2 is frequently too ④diligent or too occupied to double-check them. As a result, a judgment often feels most confident precisely at the moment when it has skipped the careful scrutiny that could have caught its own mistake, leaving the thinker ⑤unaware of how easily the impression was formed.

The immune system produces an almost limitless variety of antibodies, each shaped to latch onto one particular molecular target with remarkable ①specificity. Monoclonal antibody drugs harness this natural precision by cloning a single antibody-producing cell in the laboratory, generating an army of identical antibodies built to recognize one target, such as a protein on a cancer cell or a molecule driving an autoimmune disease. Because the antibody binds only to its intended target, these drugs tend to spare healthy tissue far more ②effectively than traditional chemotherapy, which attacks any rapidly dividing cell regardless of whether it is cancerous. Manufacturing monoclonal antibodies remains far more ③complicated than producing a conventional small-molecule pill, since living cells must be cultivated in carefully controlled bioreactors for weeks before the antibody can be purified and prepared for use. This complexity keeps monoclonal antibody treatments considerably more ④expensive than most conventional drugs, a cost that continues to ⑤resolve debates over pricing and access.

Factories that once employed hundreds of workers on an assembly line now run with a ①fraction of that staff, as robotic arms handle tasks that used to require human hands. Economists have long debated whether this shift destroys jobs or simply transforms them. Historical evidence offers some ②comfort: previous waves of automation eventually created new categories of work that no one had predicted. However, critics point out that earlier transitions unfolded over generations, giving workers ③ample time to retrain, whereas today's robots are being deployed at a pace that leaves little room for adjustment. A factory worker displaced this year cannot simply wait for a new industry to emerge decades from now. For this reason, many economists argue that the real ④challenge is not the robots themselves, but the ⑤sluggish speed at which society is expected to adapt to them.

Bacteria have been cutting up invading viral DNA for billions of years, long before any scientist thought to borrow the trick for use in a laboratory. (A) Once Cas9 arrives at the target site, it slices both strands of the DNA helix, and the cell's own repair machinery rushes in to mend the cut, often introducing a small change in the process. (B) By supplying the cell with a template during this repair step, scientists can direct that machinery to insert a specific new sequence, and what once required years of painstaking work to alter a single gene can now be accomplished within days. (C) The CRISPR-Cas9 system, as it is now known, relies on a short guide RNA that matches a specific DNA sequence, leading a scissor-like enzyme called Cas9 directly to that exact location in the genome.

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. (A) 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. This held true regardless of which environment that happened to be. (B) 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. (C) 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. Rather than assuming that memorization is a context-free process, students ought to consider deliberately varying study locations and conditions. Doing so would ensure that retrieval cues remain available regardless of how a future test is administered.

That freedom, however, comes with an important caveat about what these structures can and cannot tell us. A cluster of neurons smaller than a pea can now spontaneously organize itself into layered structures that mimic, in miniature, the architecture of a developing human brain. ( ① ) Grown from stem cells coaxed to follow the same developmental cues that guide an embryo, these brain organoids have begun firing electrical signals in patterns that faintly resemble the activity recorded in an infant's brain. ( ② ) For researchers studying disorders such as autism or schizophrenia, this offers something long unavailable: a living model of human brain development that can be observed and manipulated directly. ( ③ ) This can happen without ever touching an actual patient. ( ④ ) Because organoids lack sensory organs, a body, or any connection to the outside world, most neuroscientists argue that the structures cannot generate anything resembling subjective experience, however brain-like their electrical activity may appear. ( ⑤ ) Even so, the pace at which these organoids are growing more complex has convinced some ethicists that the field would benefit from establishing clear boundaries now, before the science outruns the conversation about what it means.

주어진 문장: Because controlled processing is so resource-intensive, repeated practice offers an efficient way to shift a skill from one category to the other. 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. ( ① ) Automatic processing occurs rapidly, requires minimal attention, and typically operates outside conscious awareness, allowing multiple automatic tasks to proceed without interfering with one another. ( ② ) Controlled processing, by contrast, unfolds more slowly, demands deliberate 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. ( ③ ) Skills that once required intense concentration, such as reading or typing, gradually become automatic through extensive practice, freeing attentional resources for other purposes. ( ④ ) This shift explains why novice drivers find it difficult to talk while merging onto a highway, whereas seasoned drivers manage the same maneuver with comparative ease. ( ⑤ ) However, automaticity carries hidden costs, since automatized responses can be triggered inappropriately by habitual cues even when circumstances have changed, occasionally producing errors that controlled deliberation would have prevented.
