Generative AI systems learn to write, draw, and compose by studying enormous collections of existing human work, much of ①which was created without the artists' knowledge or consent. Supporters of the technology argue that this process ②resembles how a human student learns by studying the masters, absorbing style and technique rather than copying specific pieces. Critics respond that the comparison ③breaks down at scale: a single AI model can absorb millions of works in days and then generate outputs that directly compete with the very artists whose work ④trained it. Courts around the world are now ⑤ask to decide whether training an algorithm on copyrighted material counts as fair use or as infringement.

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

Physicist Erwin Schrödinger devised a now-famous thought experiment not to describe an actual laboratory procedure, but ①to expose 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 ②rigged 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, ③as existing in a superposition 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 ④be considered simultaneously alive and dead until an observer opens the lid and looks inside. Schrödinger intended this image to sound obviously ridiculous, 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 further than it ⑤ever meaning to go.

The discovery of CRISPR gene-editing technology gave scientists a tool ①precise enough to correct a single mistaken letter in the human genome, raising hope for curing inherited diseases that have resisted treatment for generations. Yet the same precision that makes CRISPR so promising also makes it ②dangerous in the wrong hands. Editing a gene in a sperm, egg, or early embryo does not simply change one patient; it alters the genetic code passed down to every future generation, a decision no single person should be allowed to make ③alone. Scientific organizations around the world have therefore drawn a careful line, ⑤permitting gene editing to treat disease in existing patients while ④permitting any edit that would be inherited by their descendants. Critics worry, however, that as the technology becomes cheaper and more widely available, this line will become harder to enforce than it is to draw.

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

When people evaluate their personal contribution to water scarcity, they often consider only the water that flows directly from household taps, overlooking a far larger quantity consumed indirectly through the goods they purchase. The water footprint, a concept that extends this narrow view, _______________. Central to this concept is the notion of virtual water, the water embedded invisibly within a product, from irrigating cotton fields to livestock raised for meat. For instance, producing a kilogram of beef can require several thousand liters of water, whereas a kilogram of vegetables typically demands a fraction of that amount. Nations that import water-intensive goods rather than producing them domestically are importing virtual water from regions that may face severe shortages. Critics caution, however, that focusing exclusively on aggregate volume can mislead policymakers, since a liter of water drawn from a region suffering drought carries far greater consequences than one drawn from a water-abundant area.

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 laboratory. The CRISPR-Cas9 system relies on a short guide RNA that matches a specific DNA sequence, _______________. Once Cas9 arrives at the target site, it slices 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 insert 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.

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. (A) 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. (B) 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. (C) 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, a speed that has convinced many researchers the same platform could eventually fight diseases far beyond infectious illness.

A liver no longer has to sit inside a human body to be studied closely. (A) Unlike flat cultures grown on a plastic dish, which lose many of the cues that guide normal development, organoids let cells interact in three dimensions much as they would inside the body, yielding tissue that behaves in strikingly realistic ways. (B) This fidelity has made organoids invaluable for testing how a drug affects human tissue before any patient is exposed, and 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. (C) 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.

Scarcity cues of this kind are becoming increasingly common across online retail platforms, appearing on everything from hotel bookings to concert tickets. A shopper browsing an online store notices that a particular item is marked as "only three left in stock." ( ① ) Before seeing this notice, the shopper had regarded the item with only mild interest, uncertain whether it was worth purchasing at all. ( ② ) After seeing the notice, however, the same shopper suddenly feels a pressing urge to complete the purchase before the remaining stock disappears, even though nothing about the item itself has changed. ( ③ ) This shift in urgency illustrates how scarcity cues can transform hesitation into immediate action within moments. ( ④ ) Retailers are well aware of this dynamic, which is why such notices frequently appear even when actual stock levels are difficult for customers to verify independently. ( ⑤ ) Whether the stated scarcity is genuine or exaggerated, its psychological effect on the shopper's behavior remains remarkably similar.
