When people encounter an individual ①who appears to memorize enormous quantities of specialized information effortlessly, they often assume that person possesses an innate gift. Cognitive psychologists, however, contend that such feats rarely stem from raw talent alone. Instead, such feats arise from a learned skill known as chunking, ②whereby scattered pieces of information are consolidated into larger, meaningful units. A landmark study of chess players demonstrated this principle. When shown a board arranged according to plausible game positions, grandmasters ③reproduced the layout perfect. Yet when the same pieces were scattered randomly, their performance collapsed to the level of novices. This pattern reveals that expert memory is not larger in raw capacity but is instead organized around patterns ④accumulated through years of deliberate practice. If chunking, rather than innate aptitude, underlies expert performance, then educators should stop treating talent as fixed and destiny-bound. Curricula ought to be redesigned to cultivate pattern recognition explicitly, ⑤since doing so would grant far more students access to expertise once presumed reserved for the naturally gifted.

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.

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.

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.

Military researchers have developed weapons systems capable of identifying and engaging targets without a human pressing the final button. Advocates argue that autonomous systems can react faster than any human operator. Human rights organizations counter that removing a person from the final decision strips away moral responsibility, since _______________. Diplomatic negotiations toward an international treaty have repeatedly stalled, partly because military powers disagree on how to define autonomy precisely enough to regulate it.

The debate over nudging often centers on a single, deceptively simple question: does saving people from their own cognitive errors amount to genuine assistance or subtle manipulation? (A) Supporters respond that every choice architecture, whether intentionally designed or not, already influences behavior in some direction, so deliberately choosing a beneficial default is preferable to leaving the arrangement to chance or to the interests of profit-driven designers. (B) Opponents of nudging argue that any attempt to steer behavior, however gently, treats citizens as incapable of making sound decisions on their own and therefore undermines the very autonomy it claims to respect. (C) This rebuttal shifts the debate away from whether influence should exist at all and toward the more practical question of who should be trusted to design it and for what purpose.

John Rawls proposed an unusual thought experiment to determine what principles of justice a society ought to adopt. (A) Imagine a group of rational people gathered to design the basic rules of their future society, but placed behind what he called a veil of ignorance, unaware of their own race, gender, wealth, or social position. (B) Since no one can predict whether they will be born into privilege or poverty, each person has a strong incentive to choose rules that protect the worst-off members of society. (C) Rawls argued that rational people placed in this position would favor arrangements that guarantee basic liberties for everyone and permit unequal outcomes only when they benefit the least advantaged.

Cities are frequently several degrees warmer than the surrounding countryside, a phenomenon known as the urban heat island effect, which intensifies in summer and threatens public health. (A) This disparity arises largely because asphalt and concrete absorb solar radiation during the day and slowly release it as heat throughout the night, preventing urban areas from cooling down. Furthermore, the scarcity of vegetation in densely built areas removes a natural cooling mechanism, since plants lower temperatures by evaporating water from their leaves. (B) Another strategy, green infrastructure, incorporates rooftop gardens and tree-lined streets that provide shade while releasing moisture. In contrast, some cities have pursued permeable pavements that let water seep through and evaporate, cooling nearby surfaces. Collectively, these strategies show that reducing urban heat depends on combining approaches suited to a city's geography. (C) To address this problem, urban planners have begun implementing mitigation strategies designed to lower surface and air temperatures. One widely used solution involves reflective "cool" roofing engineered to reflect more sunlight than dark rooftops absorb.

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

Turning this tide has proven far harder than creating it, and not merely for scientific reasons. 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 multiply without competition. ( ① ) 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 effective. ( ② ) 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 enormous cost of developing it. ( ③ ) Researchers are therefore searching in unconventional places, screening soil microbes and ocean sediment for molecules that kill bacteria through new mechanisms. ( ④ ) Even genetic databases are now mined for such molecules, ones resistant strains have not yet learned to evade. ( ⑤ ) Some scientists have also revived an older approach, using viruses that infect only bacteria to hunt down resistant strains with a precision no broad-spectrum drug could ever match.
