A biosensor works by pairing a biological component, such as an enzyme or antibody, with an electronic device that ①convert a biological reaction into a signal a computer can read. When the target molecule, whether glucose in blood or a trace of a pathogen, ②binds to the biological component, it triggers a small measurable change that the device translates into a readable number. This design has already transformed diabetes management, ③letting patients monitor blood sugar continuously through a small sensor worn under the skin rather than pricking a finger several times a day. Engineers are now racing to extend the same principle ④to detect subtler targets, from cancer cells circulating in the bloodstream to trace contaminants in drinking water. The central challenge is not detecting the target but doing so reliably outside a controlled laboratory, since a sensor that performs well on a clean lab bench can behave erratically once ⑤exposed to a real body or a real river.

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 ①multiply without competition. 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 ②effective. 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 ③enormous cost of developing it. Researchers are therefore searching in ④unconventional places, screening soil microbes, ocean sediment, and even genetic databases for molecules that kill bacteria through mechanisms resistant strains have not yet learned to evade. Some scientists have also revived an older approach, using viruses that infect only bacteria to hunt down resistant strains with a ⑤carelessness no broad-spectrum drug could ever match.

A cricket contains, gram for gram, roughly as much protein as beef, yet requires a ①substantial fraction of the land, water, and feed needed to raise cattle. This efficiency has drawn growing attention from researchers looking for ways to feed a global population that continues to climb while arable land remains essentially fixed. Insects also convert feed into body mass with ②remarkable efficiency, since they are cold-blooded and therefore spend far less energy regulating body temperature than a cow or pig must. Despite these advantages, insect protein has struggled to gain ③acceptance in many cultures, where the idea of eating insects triggers a reflexive disgust that no nutritional argument alone seems able to overcome. Food companies have responded by grinding insects into a flour that disappears into protein bars, pasta, and baked goods, letting consumers ④benefit from the nutrition without ever having to look an insect ⑤in the eye.

Symbolic interactionism approaches society not as a fixed structure imposed from above but as something continuously constructed through everyday face-to-face interaction, in which individuals interpret and respond to the symbolic meanings that objects, actions, and other people hold for them. Sociologist George Herbert Mead argued that the self itself emerges through this interactive process, as individuals learn to see themselves from the perspective of others. Erving Goffman extended this framework with his dramaturgical approach, comparing social life to a theatrical performance in which individuals manage impressions and present different faces in different settings. Unlike structural theories that emphasize large institutions, symbolic interactionism focuses on the small, repeated exchanges through which shared meaning is negotiated, arguing that _______________.

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.

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. (A) 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. (B) Advances in molecular biology eventually allowed researchers to isolate a single protein from a pathogen's surface, producing vaccines with fewer side effects, and the most recent shift toward delivering genetic instructions represents the latest chapter in this story. (C) For nearly two centuries afterward, vaccine development proceeded largely by trial and error, weakening or killing a pathogen and testing whether the resulting preparation could train the immune system without causing disease itself.

Time travel to the past has long fascinated physicists and philosophers alike, but it also generates a famously troubling contradiction. (A) The story therefore loops endlessly, undermining itself at every turn rather than settling into any stable outcome. (B) If the grandfather never had children, the traveler themselves would never have been born, and could never have existed to make the trip in the first place; yet if the traveler never made the trip, the grandfather would have survived to meet the grandmother after all. (C) Suppose a traveler journeyed backward in time and, through some combination of accident and intention, prevented their own grandfather from ever meeting their grandmother.

Imagine a distant planet identical to Earth in every visible respect, except that the clear liquid its inhabitants call "water" is not H2O but a different compound, XYZ, that happens to look, taste, and behave exactly the same. (A) Even though the two speakers hold identical thoughts and mental images when they use the word, their statements refer to two different substances, because the underlying chemical composition fixes what a word ultimately picks out. (B) When an Earthling and a Twin Earthling each say the word "water," they seem to mean the same thing, since neither could tell the substances apart without a chemistry lab. (C) Philosopher Hilary Putnam used this scenario to argue that the meaning of a word is not determined solely by what happens inside a speaker's head.

People also want to actually do certain things and to actually be a certain kind of person, not merely to feel as though they had. Philosopher Robert Nozick asked his readers to imagine a machine capable of producing any experience they desired, from writing a great novel to falling in love, all indistinguishable from reality once they were plugged in. ( ① ) Neuroscientists would simply stimulate the brain to generate a lifetime of perfectly satisfying experiences, and the person floating in the tank would have no memory of ever choosing to enter it. ( ② ) If pleasure and the avoidance of pain were truly all that mattered, as classical hedonism claims, then everyone should rush to connect themselves permanently to such a machine. ( ③ ) Yet when people actually consider the offer, most hesitate, and many refuse outright. ( ④ ) Nozick took this reluctance as evidence that human beings care about more than the quality of their internal sensations. ( ⑤ ) Maintaining genuine contact with a reality beyond one's own mind, it turns out, matters just as much as how that mind happens to feel.

주어진 문장: Traditional economic models, in fact, offer no straightforward account of why unpaid, amateur labor should raise an object's perceived worth in the eyes of its very creator. Why do people often overvalue objects they have partly built themselves, even when the finished product is objectively inferior to something they could have simply purchased? ( ① ) This puzzle, which researchers named after a furniture retailer famous for selling items that require home assembly, challenges the standard economic assumption that value is determined solely by an object's inherent qualities. ( ② ) In a series of experiments, participants who assembled a plain storage box were willing to pay nearly as much for their own imperfect creation as they were for a professionally built version, despite being fully aware of its flaws. ( ③ ) Labor, it seems, functions as a kind of psychological investment: once effort has been poured into a task, individuals become reluctant to judge the outcome objectively, because doing so would require admitting that their effort was partly wasted. ( ④ ) This tendency helps explain why consumers often prefer products that demand some degree of personal assembly, even when a comparable finished item is available at a lower price and requires no time investment whatsoever. ( ⑤ )
