City governments increasingly market dense networks of surveillance cameras as a straightforward safety upgrade, ①promising faster emergency response and lower crime rates. In many cases, the technology delivers exactly what it promises, ②helping investigators identify suspects within hours rather than weeks. Yet the same infrastructure that catches criminals also creates a permanent record of where ordinary, law-abiding citizens ③go about their daily lives. Once a camera network exists, its purpose can quietly expand, often without new public debate or explicit approval. Civil liberties groups argue that a city should decide how much surveillance it wants before the cameras go up, not years afterward when the infrastructure ④is already impossible removing. Convenience installed today, in other words, can quietly ⑤become control tomorrow.

When a country physician named Edward Jenner noticed that milkmaids ①who had caught cowpox seemed immune to smallpox, he set in motion a medical revolution without fully understanding why it worked. For nearly two centuries afterward, vaccine development proceeded largely by trial and error, ②weakened or killing a pathogen and testing whether the resulting preparation could train the immune system without causing disease itself. This method produced genuine successes, eventually eliminating smallpox worldwide and reducing diseases such as polio and measles, but each new vaccine still ③required years of laboratory work with no guarantee of success. Advances in molecular biology eventually allowed researchers ④to 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 ⑤that began with an eighteenth-century doctor's curiosity about a puzzling immunity among dairy workers.

Generative AI systems learn to write, draw, and compose by studying ①enormous collections of existing human work, much of which was created without the artists' knowledge or consent. Supporters of the technology argue that this process resembles how a human student learns by studying the masters, ②absorbing style and technique rather than copying specific pieces. Critics respond that the comparison ③holds up perfectly at scale, since a single AI model can absorb millions of works in days. Courts around the world are now being asked to decide whether training an algorithm on copyrighted material counts as fair use or as ④infringement. Until clearer rules emerge, artists, developers, and publishers remain locked in a legal ⑤gray zone that satisfies almost no one.

Military researchers have developed weapons systems capable of identifying and engaging targets without a human pressing the final button, a prospect that has ①alarmed arms control experts for over a decade. Advocates within defense agencies argue that autonomous systems can react faster than any human operator and may even ②reduce casualties by removing fear and fatigue from split-second decisions. Human rights organizations counter that removing a person from the final decision strips away moral responsibility at the exact moment it matters most, since a machine cannot be held ③accountable in any meaningful sense. Diplomatic negotiations toward an international treaty have repeatedly ④succeeded, partly because military powers disagree on how to define autonomy precisely enough to regulate it. Meanwhile, the underlying technology continues to ⑤advance regardless of whether the diplomacy meant to govern it keeps pace.

Factories that once employed hundreds of workers on an assembly line now run with a ①fraction of that staff, as robotic arms handle tasks that used to require human hands. Economists have long debated whether this shift destroys jobs or simply transforms them. Historical evidence offers some ②comfort: previous waves of automation eventually created new categories of work that no one had predicted. However, critics point out that earlier transitions unfolded over generations, giving workers ③ample time to retrain, whereas today's robots are being deployed at a pace that leaves little room for adjustment. A factory worker displaced this year cannot simply wait for a new industry to emerge decades from now. For this reason, many economists argue that the real ④challenge is not the robots themselves, but the ⑤sluggish speed at which society is expected to adapt to them.

Conventional economic wisdom holds that more options are always preferable to fewer. Empirical research on consumer behavior, however, complicates this assumption considerably. When shoppers are presented with an extensive array of choices, they frequently experience heightened anxiety about making the wrong selection and, paradoxically, become less likely to make any purchase or decision at all. Businesses that recognize this dynamic have begun deliberately curating smaller, carefully selected assortments, betting that ___________ can sometimes generate more sales and greater customer satisfaction than abundance.

Blockchain technology was originally promoted as a way to remove the need for trusted middlemen. In theory, this design distributes power away from any single institution and toward the network as a whole. In practice, however, _______________, controlling enough computing power or currency to influence outcomes that were supposed to be decided collectively. Whether decentralization can survive this concentration of power remains one of the technology's most unresolved questions.

Traditional industrial systems have relied on a linear model of production, in which raw materials are extracted, transformed into goods, and eventually discarded as waste. This approach treats natural resources as if unlimited and disposal as if costless. A circular economy proposes an alternative framework in which _______________, thereby reducing the extraction of virgin resources. Central to this model is the notion that waste, rather than being an inevitable byproduct, can be redesigned as a resource for another process, much as fallen leaves nourish the trees that shed them. For example, manufacturers design products so that components can be disassembled and reused in new items once their original function ends. Some companies also lease equipment instead of selling it outright, retaining responsibility for refurbishment. Because such practices lessen dependence on finite raw materials, they reduce the environmental damage caused by mining. Consequently, the circular economy is increasingly regarded as a viable economic strategy that conserves resources for future generations.

Journalists now face the burden of verifying footage that once would have been accepted as self-evident proof. A few years ago, spotting a manipulated video required a trained eye and specialized software. ( ① ) Today, freely available applications allow almost anyone to swap a face or fabricate a voice convincingly enough to fool casual viewers within minutes. ( ② ) This shift has quietly undermined one of the oldest assumptions in human communication: that seeing and hearing something is a reasonably reliable way to confirm it happened. ( ③ ) Perhaps more troubling than any single fake video is the broader effect on public trust, sometimes called the liar's dividend, in which genuine footage can be dismissed as fabricated simply because deepfakes exist. ( ④ ) In this environment, the mere possibility of manipulation can be almost as damaging as manipulation itself. ( ⑤ )

주어진 문장: This dual function, capturing carbon while simultaneously enriching the soil, distinguishes biochar from many other carbon removal methods that offer no agricultural benefit. Among the many strategies proposed to remove carbon dioxide from the atmosphere, one of the oldest draws on an agricultural technique predating modern industry, converting organic material into a stable form of charcoal known as biochar. ① Biochar is produced through pyrolysis, a process in which crop residues or wood chips are heated in an environment with little or no oxygen, preventing the material from burning away as in an open fire. ② This process leaves behind a carbon-rich solid that resists decomposition far longer than raw organic matter, locking carbon in a form remaining stable in soil for centuries. ③ When mixed into farmland, biochar also improves soil structure, retaining moisture and nutrients otherwise lost, which can boost crop yields in depleted soils. ④ For example, farmers cultivating nutrient-poor tropical soils have reported measurable increases in productivity after adding biochar. ⑤ Nevertheless, researchers caution that the climate benefits of biochar depend on the feedstock and method used, since poorly managed pyrolysis can release as much carbon as it sequesters, undermining its own purpose. ① ② ③ ④ ⑤
