Imagine a distant planet ①identically 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 ②to look, taste, and behave exactly the same. 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. Philosopher Hilary Putnam ③used this scenario to argue that the meaning of a word is not determined solely by what happens inside a speaker's head. 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, not personal belief, ④fixes what a word ultimately picks out. Meaning, Putnam concluded, depends partly on the world outside the mind, not merely on the private mental states of ⑤whoever happens to be speaking.

A hamburger patty need not come from a slaughtered animal at all if a small sample of muscle cells ①can be persuaded to multiply inside a steel tank. Cultured meat begins with a biopsy of animal muscle tissue, from which scientists isolate cells ②capable of dividing repeatedly, then feed those cells a nutrient broth that supplies the sugars, proteins, and minerals an animal's bloodstream would normally provide. Inside a bioreactor, the cells multiply across scaffolding ③designed to encourage them to align into fibers, gradually thickening into something that begins to resemble muscle tissue rather than a shapeless clump of cells. Supporters argue that because the process never requires raising and slaughtering a whole animal, it could ④shrink the land, water, and greenhouse gas emissions associated with conventional meat production. Skeptics counter that producing the specialized broth at a large enough scale remains prohibitively expensive, meaning cultured meat is unlikely ⑤competing with conventional meat in price until the technology matures considerably further.

Biodegradable plastics have been promoted as a promising solution to plastic waste, since they ①are designed to decompose into natural substances rather than persist for centuries. Manufacturers derive these materials from renewable resources such as corn starch, blending them with additives that ②accelerates microbial breakdown once discarded. However, their environmental benefits are often exaggerated, largely because decomposition depends on specific conditions rarely ③found outside industrial composting facilities. For example, a bag labeled biodegradable may take years, not the weeks advertised, to break down in a landfill or ocean, where temperature and microbial activity remain low. In addition, when mixed with conventional plastics in recycling streams, they can contaminate the process, ④weakening the quality of materials produced afterward. Some engineers therefore compare biodegradable plastics to a bridge that leads nowhere unless paired with infrastructure that completes the journey. Ultimately, realizing their genuine potential requires not only technological refinement but also facilities capable of ⑤providing the precise conditions decomposition demands.

Change blindness refers to a striking limitation of human perception in which observers fail to notice substantial ① alterations to a visual scene, provided the change occurs during a brief disruption such as an eye movement or a momentary obstruction. In a now-famous demonstration, researchers showed participants two versions of a photograph in alternation ②, separated by a short blank screen, and asked them to identify what had changed. Even when an entire building disappeared or a person's clothing shifted color, many viewers stared at the picture without detecting anything unusual ③. This phenomenon occurs because visual attention, rather than passively recording every detail like a camera, actively selects only a narrow ④ subset of information for processing at any given moment. Whatever falls outside that narrow spotlight is represented only sparsely, if at all, leaving it vulnerable to being overwritten without notice. Consequently, change blindness demonstrates that our impression of a rich, complete visual world is, to a surprising extent, an illusion constructed by the mind, not an unreliable ⑤ record of external reality.

For patients born with a single faulty gene, the disease has traditionally been treated ①indirectly, managing symptoms for a lifetime rather than addressing the genetic error itself. Gene therapy attempts something more ambitious: delivering a corrected copy of the gene directly into a patient's cells, often using a ②reinforced virus stripped of its ability to cause illness as a delivery vehicle. Once inside the nucleus, the corrected gene can begin producing the protein the patient's body had always lacked, in some cases ③reversing symptoms that medication alone had never been able to touch. Early trials were haunted by serious ④setbacks, including cases in which the delivery virus triggered a dangerous immune reaction. Refined delivery methods have since made the treatment considerably ⑤safer, and regulators in several countries have now approved gene therapies for a small but growing number of rare inherited disorders.

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.

The human gut hosts trillions of microorganisms whose combined genetic material outnumbers that of the human genome itself many times over. (A) A microbiome disrupted by antibiotics, poor diet, or chronic stress can leave the gut lining more permeable than it should be, allowing substances to leak into the bloodstream that would normally stay contained. (B) Once dismissed as passive hitchhikers, these bacteria are now understood to actively shape digestion, regulate immune responses, and even influence the production of chemicals that affect mood and behavior. (C) Researchers studying this connection have found that transplanting gut bacteria from a healthy donor into a patient can relieve symptoms of certain digestive disorders, though the microbiome varies enormously between individuals, so a treatment that helps one person's gut may do little for someone else's.

주어진 문장: In simple terms, this process prevents carbon dioxide from ever reaching the atmosphere in the first place. 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. ① 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. ② 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 functions as a bridge technology, allowing heavy industries to keep operating while more sustainable alternatives are developed. ③ 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. ④ However, critics contend that the technology remains prohibitively expensive and that building pipelines requires investments few companies make voluntarily. ⑤ Despite such concerns, many governments continue funding pilot projects, convinced that this technology will play an indispensable role in reaching emission targets. ① ② ③ ④ ⑤

Unlike Bentham's single tower, today's surveillance is frequently decentralized and voluntary, which some theorists claim makes it more effective precisely because it no longer feels like surveillance at all. Philosopher Jeremy Bentham designed the panopticon, a prison structure in which a central watchtower allows a single guard to observe every cell, while inmates can never determine whether they are actually being watched at any given moment. ( ① ) French theorist Michel Foucault later transformed this architectural idea into a broader theory of power, arguing that the mere possibility of being observed is often sufficient to produce obedient behavior. ( ② ) Foucault extended this logic beyond prisons to schools, hospitals, and workplaces, suggesting that modern institutions increasingly rely on continuous, often invisible observation rather than physical force to maintain order. ( ③ ) Contemporary scholars have applied Foucault's framework to digital surveillance, arguing that smartphones and workplace monitoring software recreate panoptic conditions on a vastly larger scale. ( ④ ) These technologies allow observation to occur almost anywhere, at almost any time. ( ⑤ )

That trajectory has continued to accelerate ever since, each new generation of vaccine technology arriving faster than the one before it. 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. ( ① ) 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. ( ② ) This method produced genuine successes, eventually eliminating smallpox worldwide and reducing diseases such as polio and measles. ( ③ ) Each new vaccine, however, still required years of laboratory work with no guarantee of success. ( ④ ) 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. ( ⑤ ) 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.
