A single fertilized egg eventually ①gives rise to every cell type in the human body, from neurons to bone, a feat that has fascinated biologists for more than a century. Embryonic stem cells retain much of that original versatility, capable in principle of ②develop into almost any tissue, which is why researchers have long viewed them as a promising raw material for repairing damaged organs. Because harvesting these cells traditionally required ③destroying a human embryo, the research provoked ethical objections fierce enough to slow funding and legislation in several countries for years. A breakthrough arrived when scientists discovered that ordinary adult skin cells could be ④reprogrammed, through the introduction of a handful of specific genes, into a state resembling embryonic versatility without ever touching an embryo. These induced pluripotent cells have not entirely erased the ethical debate, but they have opened a path for stem cell research that far more scientists and funding agencies are willing ⑤to support.

When people encounter an individual ①who appears to memorize enormous quantities of specialized information effortlessly, they often assume that person possesses an innate gift. Cognitive psychologists, however, contend that such feats rarely stem from raw talent alone. Instead, such feats arise from a learned skill known as chunking, ②whereby scattered pieces of information are consolidated into larger, meaningful units. A landmark study of chess players demonstrated this principle. When shown a board arranged according to plausible game positions, grandmasters ③reproduced the layout perfect. 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 ④accumulated through years of deliberate practice. If chunking, rather than innate aptitude, underlies expert performance, then educators should stop treating talent as fixed and destiny-bound. Curricula ought to be redesigned to cultivate pattern recognition explicitly, ⑤since doing so would grant far more students access to expertise once presumed reserved for the naturally gifted.

German sociologist Ferdinand Tönnies distinguished between two fundamentally different forms of social organization, ①which he termed Gemeinschaft and Gesellschaft. Gemeinschaft, often ②translated as community, describes relationships bound by close kinship, shared tradition, and face-to-face familiarity, typical of small villages where individuals know one another across an entire lifetime and act according to unwritten customs. Gesellschaft, often translated as society, describes relationships organized around impersonal contracts, self-interest, and formal law, typical of large cities where interactions occur between relative strangers ③who cooperate for specific, limited purposes. Tönnies did not regard one form as simply superior to the other; rather, he saw the shift from Gemeinschaft toward Gesellschaft as a defining feature of modernization, one that brought greater efficiency and individual freedom while ④weaken the dense emotional bonds that once held communities together. Contemporary sociologists continue to debate whether digital networks represent a genuine revival of Gemeinschaft-style community or merely ⑤extend Gesellschaft's impersonal logic into new spaces.

Many households save far less for retirement than conventional financial advice would recommend, not necessarily because they ①lacks the resources to do so, but because a combination of procrastination, present bias, and the discomfort of forgoing current consumption repeatedly delays the decision to begin saving. Recognizing this gap between intention and action, some economists have proposed a savings program in which employees commit today to ②allocating a portion of their future salary increases toward retirement savings, rather than being asked to reduce their current take-home pay immediately. Because the sacrifice applies only to income not yet received, the commitment ③feels far less painful than an equivalent reduction in present earnings would, making employees considerably more willing to enroll. Once enrolled, the contribution rate automatically rises with each subsequent raise, ④gradually increasing savings without requiring any further deliberate action from participants. Field trials of such programs have reported substantial increases in average savings rates over several years, alongside participant satisfaction that ⑤remains notably high.

When people look back on a multi-day journey, they rarely ①recall every hour with equal clarity; instead, memory tends to compress the entire experience into just a few representative moments. Psychologists have found that two points carry disproportionate weight in this process: the single moment when emotion, whether joy or discomfort, ②reached its highest intensity, and whatever happened right before the experience concluded. Consider two hikers who complete an identical five-day trek. The first finishes with a grueling, rain-soaked final climb, while the second enjoys a calm, scenic descent on the last afternoon despite having ③endure an equally difficult ascent earlier in the trip. Even though both hikers faced comparable hardship overall, the second is far more likely to remember the journey fondly, simply because the trip ④ended pleasantly. This pattern reveals that overall satisfaction is not calculated as an average of every experienced moment; rather, it is shaped disproportionately by whichever moments ⑤felt most intense and by however the experience happened to end.

Blockchain technology was originally promoted as a way to remove the need for trusted middlemen, allowing strangers to exchange value directly and verify transactions through a shared, ①tamper-resistant ledger rather than through a bank or government agency. In theory, this design distributes power away from any single institution and toward the network as a whole. In practice, however, a small number of large players have come to ②dominate many blockchain networks, controlling enough computing power or currency to influence outcomes that were supposed to be decided collectively. Critics note a further irony: when something goes wrong, such as a hacked exchange or a lost password, there is often ③ample institutional support to appeal to, since the entire system was designed precisely to eliminate that kind of central authority. Whether decentralization can ④survive this concentration of power remains one of the technology's most ⑤unresolved questions.

As more schools shift toward digital textbooks and online assignments, a student without reliable internet access at home faces a disadvantage that has little to do with talent or effort. Some policymakers initially treated internet access as a convenience, comparable to cable television, rather than as infrastructure essential to modern life. That assumption is increasingly being reconsidered, particularly as _______________. Closing this divide will require more than simply distributing devices.

Social media platforms rarely show users a neutral stream of information. (A) Over time, users exposed to a steady diet of emotionally charged content may come to believe that extreme opinions are far more common than they actually are. (B) Instead, recommendation algorithms are optimized to maximize engagement, and content that provokes strong emotion tends to hold attention longer than balanced reporting ever could. (C) Researchers describe this as a distorted mirror: the platform reflects not society as it truly is, but a version shaped by whatever keeps people scrolling.

Desalination, the process of removing dissolved salts from seawater to produce fresh water, has increasingly been adopted by coastal regions facing chronic water scarcity. (A) 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. (B) Nevertheless, desalination remains an inherently costly and environmentally burdensome solution, a fact often overlooked amid enthusiasm for ending water shortages. 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. (C) 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. 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.

주어진 문장: No individual, he pointed out, could realistically process every piece of available information before choosing. Classical economic theory long assumed that decision makers gather all relevant information, calculate every possible outcome, and select the single option that maximizes their benefit. ( ① ) Herbert Simon, however, questioned this assumption, arguing that human beings operate under real constraints of time, knowledge, and mental capacity that make such exhaustive calculation practically impossible. ( ② ) Instead of searching endlessly for the theoretically perfect choice, people typically stop once they find an option that seems good enough to meet their immediate needs, a strategy Simon termed satisficing. ( ③ ) A shopper comparing refrigerators, for example, rarely examines every model available; she instead sets a few practical criteria, such as price and size, and selects the first appliance that satisfies them adequately. ( ④ ) This approach is not a failure of reasoning but rather a sensible adaptation to a world where information is costly and time is genuinely limited. ( ⑤ ) Consequently, models assuming unlimited rationality often fail to predict actual behavior, while frameworks acknowledging these cognitive boundaries offer a far more realistic account of how ordinary decisions are actually made.
