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

Bacteria have been cutting up invading viral DNA for billions of years, long before any scientist thought to borrow the trick for use in a ①laboratory. The CRISPR-Cas9 system, as it is now known, relies on a short guide RNA that ②matches a specific DNA sequence, leading a scissor-like enzyme called Cas9 directly to that exact location in the genome. Once Cas9 arrives at the target site, it ③repairs both strands of the DNA helix, and the cell's own repair machinery rushes in to mend the cut, often introducing a small change in the process. By supplying the cell with a template during this repair step, scientists can direct that machinery to ④insert a specific new sequence rather than merely disabling the original gene. What once required years of painstaking work to alter a single gene can now be accomplished within days, a shift in ⑤speed that has reshaped nearly every corner of biological research.

Sensors buried in the soil now report moisture levels in real time, drones survey entire fields for signs of disease within minutes, and automated systems adjust irrigation without a farmer ever walking the rows. For large operations with the capital to invest, these tools have ①measurably increased yields while ②reducing water waste, addressing two problems that traditional farming has struggled with for generations. Smaller family farms, however, often ③cannot afford the upfront cost of this equipment, and some worry that the gap between high-tech and traditional operations will only widen as the technology advances further. There is also a quieter cultural cost that rarely appears in productivity reports: generations of farming knowledge risk being ④preserved by dashboards and automated alerts that few young farmers are taught to question, a loss productivity reports rarely ⑤capture.

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. 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. Philosophers, however, are troubled by a version of the same device that malfunctions: instead of destroying the original, it leaves the original body intact while still creating a perfect duplicate elsewhere. 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 that one of them is the real continuation of the person who entered the machine. This malfunction reveals that _______________.

German sociologist Ferdinand Tönnies distinguished between two fundamentally different forms of social organization, which he termed Gemeinschaft and Gesellschaft. Gemeinschaft, often translated 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. 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 who 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 _______________.

Suppose a mysterious being with a near-perfect track record of predicting human choices presents a player with two boxes. (A) The player may choose to take only Box B, or to take both boxes, and the prediction has already been made and cannot change. (B) Box A always contains a visible thousand dollars, while Box B contains either a million dollars or nothing at all, depending on a prediction the being made before the game even began. (C) One line of reasoning says taking both boxes is strictly better, since whatever is already inside the boxes cannot be altered by the player's choice at this point, while a second line of reasoning says taking only Box B is better, given the being's near-perfect accuracy.

Blockchain technology was originally promoted as a way to remove the need for trusted middlemen, allowing strangers to exchange value directly through a shared, tamper-resistant ledger. (A) In practice, however, a small number of large players have come to dominate many blockchain networks, controlling enough power to influence outcomes that were supposed to be decided collectively. (B) In theory, this design distributes power away from any single institution and toward the network as a whole. (C) Critics note a further irony: when something goes wrong, there is often no institution left to appeal to, since the system was designed to eliminate central authority.

주어진 문장: This curvature reflects a broader principle: sensitivity to change diminishes as the underlying quantity grows, whether that quantity represents a gain or a loss. Prospect theory proposes that the subjective value of money is not a straight line but a curved function, differing sharply from the assumptions of classical economic models. ( ① ) In the domain of gains, the function bends downward as amounts increase, so the psychological difference between earning zero and one hundred dollars feels far greater than between earning one thousand and eleven hundred. ( ② ) A parallel pattern appears among losses, where the curve bends in the opposite direction, yet sensitivity still fades as the amount grows larger. ( ③ ) This tendency, known as diminishing sensitivity, explains why a shopper barely notices a ten dollar increase on a two thousand dollar purchase, though the same ten dollars would matter enormously as the price of a meal. ( ④ ) Researchers illustrate this curvature with graphs shaped like an S turned sideways, sloping gently near the center and flattening toward both extremes. ( ⑤ ) Understanding this curvature allows economists to predict decisions that a simple, linear model of value could never anticipate.

During recent years, this gap became impossible to ignore, as families in rural areas or low-income neighborhoods struggled to complete schoolwork that assumed a stable connection and a personal device. 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. ( ① ) Some policymakers initially treated internet access as a convenience, comparable to cable television, rather than as infrastructure essential to modern life. ( ② ) That assumption is increasingly being reconsidered, particularly as more essential services move online by default. ( ③ ) Closing this divide will require more than simply distributing devices. ( ④ ) It will demand sustained investment in the physical networks that carry information into every home, regardless of income or location. ( ⑤ )

The software company, in turn, may argue that no algorithm can be expected to be perfect. Hospitals are increasingly adopting artificial intelligence tools that can scan medical images and flag potential tumors faster than experienced radiologists. ( ① ) When an AI system misses a diagnosis that a human doctor would likely have caught, responsibility becomes difficult to assign. ( ② ) The doctor may argue that they simply trusted a tool the hospital required them to use. ( ③ ) The hospital, meanwhile, may argue that the software company guaranteed its accuracy. ( ④ ) Until legal systems clarify this chain of responsibility, patients harmed by an algorithmic error may find themselves with no clear party to hold accountable. ( ⑤ )
