The discovery of CRISPR gene-editing technology gave scientists a tool precise enough ①to correct a single mistaken letter in the human genome, raising hope for curing inherited diseases that have resisted treatment for generations. Yet the same precision that makes CRISPR so promising also makes it dangerous in the wrong hands. Editing a gene in a sperm, egg, or early embryo does not simply change one patient; it alters the genetic code ②passed down to every future generation, a decision no single person should ③allow to make alone. Scientific organizations around the world have therefore drawn a careful line, ④permitting gene editing to treat disease in existing patients while banning any edit that would be inherited by their descendants. Critics worry, however, that this line will become harder to enforce than it ⑤is to draw.

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.

John Rawls proposed an unusual thought experiment to determine what principles of justice a society ought to adopt. Imagine a group of rational people gathered to design the basic rules of their future society, but placed behind what he called a veil of ignorance, a condition under which none of them knows their own race, gender, wealth, talents, or social position in advance. Since no one can predict whether they will be born into privilege or poverty, _______________. Rawls argued that rational people placed in this position would not gamble on inequality; instead, they would favor arrangements that guarantee basic liberties for everyone and permit unequal outcomes only when those outcomes actually benefit the least advantaged.

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. _______________. 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. Advances in molecular biology eventually allowed researchers to isolate a single protein from a pathogen's surface rather than using the whole organism, producing vaccines with fewer side effects and a more predictable safety profile. The most recent shift, toward delivering genetic instructions rather than proteins themselves, represents the latest chapter in a story that began with an eighteenth-century doctor's curiosity about a puzzling immunity among dairy workers.

Cities are frequently several degrees warmer than the surrounding countryside, a phenomenon known as the urban heat island effect, which intensifies in summer and threatens public health. This disparity arises largely because asphalt and concrete absorb solar radiation during the day and slowly release it as heat throughout the night, preventing urban areas from cooling down. Furthermore, the scarcity of vegetation in densely built areas removes a natural cooling mechanism, since plants lower temperatures by evaporating water from their leaves. To address this problem, urban planners _______________. One widely used solution involves reflective "cool" roofing engineered to reflect more sunlight than dark rooftops absorb. Another strategy, green infrastructure, incorporates rooftop gardens and tree-lined streets that provide shade while releasing moisture. In contrast, some cities have pursued permeable pavements that let water seep through and evaporate, cooling nearby surfaces. Collectively, these strategies show that reducing urban heat depends on combining approaches suited to a city's geography.

As efforts to curb greenhouse gas emissions intensify, industries unable to eliminate carbon dioxide from their processes have turned to a technology known as carbon capture and storage. This technology involves separating carbon dioxide from the exhaust of power plants before it is released into the atmosphere, then transporting the captured gas for underground injection. Once injected into porous rock formations, the gas is trapped beneath layers of impermeable rock that prevent it from escaping into the air. Proponents argue that carbon capture and storage _______________. For instance, cement and steel production, both of which release carbon dioxide as an unavoidable byproduct of chemical reactions, are considered prime candidates for this approach. However, critics contend that the technology remains prohibitively expensive and that building pipelines requires investments few companies make voluntarily. Despite such concerns, many governments continue funding pilot projects, convinced that this technology will play an indispensable role in reaching emission targets.

A printer that once produced only plastic prototypes can now deposit living cells layer by layer to build a structure that begins to resemble actual tissue. (A) Printing a solid organ such as a kidney remains a far greater challenge, because internal cells starve without their own blood supply, so researchers are focusing on hybrid strategies, printing a rough scaffold and then allowing the tissue to mature and grow its own vasculature over time. (B) Printing a flat patch of skin or a simple blood vessel has already moved from laboratory curiosity to early clinical testing, since these tissues are thin enough for nutrients to reach every cell by diffusion. (C) Bioprinting adapts the logic of conventional 3D printing, replacing plastic filament with a specialized ink made of living cells suspended in a gel that supports their survival while the shape sets.

Turning this tide has proven far harder than creating it, and not merely for scientific reasons. Every time an antibiotic kills off a population of bacteria, a handful of cells carrying a random mutation that resists the drug are left behind to multiply without competition. ( ① ) Repeated over decades, across hospitals, farms, and households worldwide, this simple process of natural selection has produced strains of bacteria that survive treatments once considered reliably effective. ( ② ) The pharmaceutical industry, meanwhile, has slowed the pace at which new antibiotics reach the market, since a drug meant to be taken for only a week or two rarely earns back the enormous cost of developing it. ( ③ ) Researchers are therefore searching in unconventional places, screening soil microbes and ocean sediment for molecules that kill bacteria through new mechanisms. ( ④ ) Even genetic databases are now mined for such molecules, ones resistant strains have not yet learned to evade. ( ⑤ ) Some scientists have also revived an older approach, using viruses that infect only bacteria to hunt down resistant strains with a precision no broad-spectrum drug could ever match.

Cultural relativism transformed fields ranging from anthropology to international development, encouraging researchers to suspend quick judgment and seek local meaning before drawing conclusions. When anthropologists first began systematically studying societies far removed from their own, many unconsciously judged unfamiliar customs against the standards of their home culture, a tendency now known as ethnocentrism. ( ① ) Cultural relativism emerged as a corrective principle, holding that a society's practices should be understood within their own cultural context rather than measured against an outside standard presumed to be universal. ( ② ) Anthropologist Franz Boas argued that no culture possesses an inherently superior set of values, and that apparent oddities, once examined closely, typically serve coherent functions within their own social systems. ( ③ ) Critics caution, however, that taken to an extreme, the principle risks excusing practices that cause genuine harm. ( ④ ) Refusing to judge any custom by outside standards, they note, can make it difficult to criticize injustice wherever it occurs. ( ⑤ )

주어진 문장: Such admiration is common, for instance, toward chess grandmasters, medical diagnosticians, or professional musicians who seem to recall vast bodies of specialized knowledge without visible strain. When people encounter an individual who appears to memorize enormous quantities of specialized information effortlessly, they often assume that person possesses an innate gift. ( ① ) Cognitive psychologists, however, contend that such feats rarely stem from raw talent alone. Instead, such feats arise from a learned skill known as chunking, whereby scattered pieces of information are consolidated into larger, meaningful units. ( ② ) A landmark study of chess players demonstrated this principle. When shown a board arranged according to plausible game positions, grandmasters reproduced the layout perfectly. ( ③ ) Yet when the same pieces were scattered randomly, their performance collapsed to the level of novices. This pattern reveals that expert memory is not larger in raw capacity but is instead organized around patterns accumulated through years of deliberate practice. ( ④ ) If chunking, rather than innate aptitude, underlies expert performance, then educators should stop treating talent as fixed and destiny-bound. ( ⑤ ) Curricula ought to be redesigned to cultivate pattern recognition explicitly, since doing so would grant far more students access to expertise once presumed reserved for the naturally gifted.
