It would be comforting to believe that anything sufficiently large or obvious appearing ①within our field of vision will automatically capture our attention, yet decades of research into inattentional blindness suggest otherwise. When people are absorbed ②in a demanding task, such as counting how many times a ball is passed between players, they frequently fail to notice an unexpected and conspicuous event unfolding in plain sight, even something as unlikely as a person in a costume walking through the scene. This failure does not stem from a defect in the eyes, which register ③the stimulus perfectly well, but from the fact that conscious perception depends heavily on where attention has been directed. Policymakers ought to take this finding more seriously than they currently do, because it implies that simply placing ④a warning sign within someone's visual range offers no guarantee that it will be consciously registered. Designing safer environments, therefore, requires account ⑤ for the limits of attention itself, not merely assuming that visibility alone ensures awareness.

Suppose a mad scientist removed a living brain from its body, ①placed it in a vat of nutrient fluid, and connected its neurons to a supercomputer capable of generating perfectly realistic sensations. The brain would experience a full and convincing world, complete with a sky, a body, and other people, without ever ②suspecting that none of it existed outside the simulation. This scenario, unsettling as it sounds, raises a genuinely difficult question for anyone ③confident in their own perception: how could a person ever prove that they are not that very brain right now? Ordinary evidence cannot help, since any proof gathered through the senses would itself ④be generated by the same simulation being tested. Some philosophers conclude that absolute certainty about the external world is simply unattainable, while others argue that the mere possibility of deception, however vivid, ⑤are not sufficient reason to abandon our everyday trust in what we perceive.

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 ①unlimited and disposal as if costless. A circular economy proposes an alternative framework in which materials are kept in continuous use through reuse, repair, and recycling, thereby ②reducing 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 ③increase the environmental damage caused by mining. Consequently, the circular economy is increasingly regarded as a ④viable economic strategy that ⑤conserves resources for future generations.

Economists have long debated whether prosperity and environmental quality are fundamentally ①opposed, or whether the relationship between them changes shape as an economy matures. The Environmental Kuznets Curve, a hypothesis borrowed from earlier theories of income inequality, proposes that pollution initially ②rises alongside economic growth before eventually declining once a society crosses a certain threshold of wealth. In its early stages, industrializing nations ③prioritize output over conservation, treating clean air and water as expendable costs of development to be addressed later. Beyond a certain point, however, rising incomes generate both the technological capacity and the political will to demand ④more lenient regulation, so degradation begins to reverse even as production keeps expanding. Some scholars regard this trajectory as a ⑤reassuring paradox, suggesting that the very growth blamed for ecological harm may eventually finance its own repair. Critics, by contrast, argue that the curve rests on a narrow selection of pollutants that happen to decline with wealth, while ignoring greenhouse gases and resource depletion, which show no comparable tendency to fall.

When engineers design the software that controls a self-driving car, they inevitably face a question that philosophers have debated for ①decades. If a crash becomes unavoidable, should the vehicle protect its own passenger at all costs, or should it be programmed to ②minimize total harm, even if that means steering toward the person inside? Surveys reveal an uncomfortable ③contradiction: most people say a car should be programmed to save the greater number of lives, yet the same people admit they would never buy a vehicle designed to sacrifice its own owner. This gap between the ideal and the personal choice suggests that ethical programming cannot be settled by public opinion alone. Manufacturers, regulators, and philosophers must instead agree on ④transparent rules before autonomous vehicles are ⑤forbidden to make such decisions on the road.

When a resource is shared among many users, none of whom bears the full cost of its depletion, _______________. This dynamic, famously labeled the tragedy of the commons, describes how shared pastures and fisheries can be degraded even when every participant privately understands the danger of overuse. A single herder who adds one more animal to a communal pasture gains the entire benefit of that addition, whereas the resulting damage to the grass is shared among other herders who depend on the land. Because self-interest offers no incentive to restrain consumption unilaterally, the resource tends to be exhausted long before any user intends such an outcome. For decades, economists assumed that only two remedies existed: strict regulation or the conversion of shared resources into private property. Elinor Ostrom challenged this assumption, however, by documenting communities that had sustainably managed fisheries and forests for generations through locally devised rules and mutual monitoring rather than external control.

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.

Many households save far less for retirement than conventional financial advice would recommend. Some economists have proposed a savings program in which employees commit today to allocating a portion of their future salary increases toward retirement savings, rather than being asked to reduce their current take-home pay immediately. Field trials of such programs have reported substantial increases in average savings rates. This approach demonstrates that savings policy grounded in realistic assumptions about human psychology can prove considerably more ___________ than policy grounded in the assumption that individuals will always act in strict accordance with their own long-term rational interests.

Imagine a man locked inside a room who does not understand a single word of Chinese, yet who possesses a giant rulebook written entirely in English, and who uses it to answer notes slipped in through a slot. (A) This scenario was designed to challenge the assumption that a computer running a sophisticated program truly understands language simply because it produces convincing output. (B) Yet the man inside understands nothing at all; he is merely manipulating shapes according to formal rules, without grasping their meaning. (C) From the perspective of a native speaker reading the responses, the room seems to understand Chinese perfectly.

Confined in this controlled setting, the organisms grow far faster than they ever would in the wild. Long before humans learned to drill for oil, microorganisms had already mastered the art of converting sunlight and carbon dioxide into stored chemical energy. ( ① ) Modern biofuel research borrows this ability, cultivating algae or engineered bacteria in large tanks. ( ② ) There, they can be coaxed into producing oils and sugars that can be refined into fuel usable in existing engines. ( ③ ) Unlike crops grown for corn-based ethanol, which compete directly with food production for arable land, many algae strains can thrive in shallow ponds, wastewater, or even coastal seawater unsuitable for conventional agriculture. ( ④ ) Engineers have also learned to tinker with the metabolic pathways of these organisms, boosting oil yield far beyond what any wild strain would naturally produce on its own. ( ⑤ ) Despite this progress, producing biofuel at a cost competitive with fossil fuel remains difficult, since harvesting and processing the organisms consumes a substantial share of the energy the fuel itself will eventually provide.
