Working memory refers to the mental workspace in which information ①is temporarily held and manipulated while a person performs a cognitive task. Such tasks include solving an arithmetic problem, following a rapid conversation, or holding a phone number in mind before dialing it. In the mid-twentieth century, the psychologist George Miller proposed that this workspace could accommodate roughly seven discrete items. His claim proved so influential that it ②become widely known as the magic number seven. Subsequent research, however, revealed that Miller's estimate was somewhat generous, since it failed to account for the complexity of the material ③being remembered. Nelson Cowan later argued that when rehearsal strategies ④are prevented and attention is tightly controlled, genuine capacity hovers closer to four items rather than seven. This discrepancy suggests that what earlier studies had measured was not raw storage capacity itself but a hybrid quantity ⑤inflated by clever strategies. Contemporary psychologists therefore distinguish between the fixed limit of working memory and the flexible techniques that allow individuals to transcend that limit.

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 ①none 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, each person has a strong incentive to choose rules that ②protect the worst-off members of society, rather than rules that merely favor whichever group they happen to belong to. 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 ③benefit the least advantaged. Justice, on this view, is what ④impartial reasoning produces once self-interest is ⑤maximized.

Physicist Erwin Schrödinger devised a now-famous thought experiment not to describe an actual laboratory procedure, but to ①conceal an absurdity hidden within a leading interpretation of quantum mechanics. Imagine a cat sealed inside a closed box together with a radioactive atom, a Geiger counter, and a vial of poison gas rigged to break open the instant the atom decays. Because the atom's decay is governed by genuine quantum randomness, standard quantum theory describes the atom, before anyone looks, as existing in a ②superposition of having decayed and not having decayed at the same time. If the theory is applied consistently to the entire box, the cat itself would have to be considered ③simultaneously alive and dead until an observer opens the lid and looks inside. Schrödinger intended this image to sound obviously ④ridiculous, using the cat's absurd fate to question whether the act of observation truly determines physical reality, or whether the mathematics is simply being pushed ⑤further than it was ever meant to go.

A liver no longer has to sit inside a human body to be studied closely. By coaxing stem cells to organize themselves within a nutrient-rich gel, scientists can now grow miniature three-dimensional structures called organoids, which reproduce much of the architecture and function of a real organ. Unlike flat cultures grown on a plastic dish, organoids let cells interact in three dimensions much as they would inside the body, yielding tissue that behaves in strikingly realistic ways. This fidelity has made organoids invaluable for testing how a drug affects human tissue before any patient is exposed, _______________. Some laboratories have even grown organoids from a single patient's own cells, raising the possibility of trialing a treatment on a miniature copy of that patient's organ before committing to an actual course of therapy.

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. 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. 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. _______________. Researchers are therefore focusing on hybrid strategies, printing a rough scaffold and then allowing the tissue to mature and grow its own vasculature over time, rather than attempting to print every vessel directly.

Consider a village green shared freely by every herder in the community, where each individual may graze as many animals as they wish without paying any fee. (A) The cost of the additional grazing, however, is spread thinly across every herder who uses the green, so no single individual bears more than a tiny fraction of the damage. (B) From the perspective of any single herder, adding one more animal to the shared pasture brings a clear personal benefit, since the extra income belongs entirely to that herder alone. (C) Because this calculation favors adding more animals for every rational herder, the shared pasture is gradually overgrazed until it can no longer support any animals at all.

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. (A) 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. (B) 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. (C) Researchers are therefore searching in unconventional places, screening soil microbes and even genetic databases for new molecules, and some have also revived an older approach using viruses that infect only bacteria to hunt down resistant strains.

The cell then acts as a temporary factory, translating that instruction into an actual protein without ever altering the cell's permanent genetic code. For decades, most vaccines worked by injecting a weakened or inactivated version of a pathogen, coaxing the immune system into recognizing an enemy it had never truly fought. ( ① ) mRNA vaccines take a fundamentally different route, delivering only a short genetic instruction wrapped in a protective lipid capsule, one that tells the body's own cells how to manufacture a single harmless piece of a virus's outer surface protein. ( ② ) Once those cells display the fragment, the immune system learns to recognize it as foreign and builds a defense, without ever having encountered the actual pathogen. ( ③ ) Because the vaccine contains no live virus and cannot alter a cell's own DNA, developers can redesign the genetic instructions within weeks whenever a pathogen mutates. ( ④ ) This is far shorter than the years-long process required for traditional vaccines. ( ⑤ ) This speed, first proven on a global scale during a recent pandemic, has convinced many researchers that the same platform could eventually be adapted to fight diseases far beyond infectious illness, including certain cancers.

주어진 문장: This reconsideration stems primarily from a robust experimental pattern documented across numerous psychological studies conducted over the past several decades. It is often assumed that memory operates independently of bodily context, yet research suggests that this assumption deserves reconsideration. ( ① ) When information is learned under a particular physiological or emotional condition, retrieval tends to improve if that same condition is reinstated at recall, a phenomenon researchers call state-dependent memory. ( ② ) Individuals who study while mildly anxious, for instance, often recall material more accurately when tested under similarly anxious conditions than when tested while calm, even though calmness is typically considered more conducive to concentration. ( ③ ) This finding should prompt educators to reconsider the assumption that a single optimal testing environment exists for every learner, since matching internal states across encoding and retrieval provides retrieval cues that a mismatched state cannot supply. ( ④ ) Critics might argue that such effects are minor and inconsistent, yet accumulated evidence across pharmacological and emotional studies is difficult to dismiss. ( ⑤ ) Policymakers designing assessments should therefore weigh not only content difficulty but also the physiological continuity between preparation and examination, since ignoring this dimension risks underestimating certain students' actual knowledge.

This malfunction, harmless as it sounds, reveals something troubling: memory and psychological continuity alone cannot fully settle what personal identity actually requires. Imagine a teleportation device that scans every atom in your body, transmits that information to a distant station, and reconstructs an exact physical duplicate there, while destroying the original body in the process. ( ① ) From the traveler's point of view, stepping into the machine and stepping out on the other side would feel utterly seamless, complete with continuous memories and a sense of having simply walked through a door. ( ② ) Philosophers, however, are troubled by a version of the same device that malfunctions. ( ③ ) Instead of destroying the original, it leaves the original body intact while still creating a perfect duplicate elsewhere. ( ④ ) Now two people exist, each with identical memories and an equally strong claim to being the original traveler, and there is no principled way to say which one is the real continuation of the person who entered the machine. ( ⑤ )
