A single fertilized egg eventually ①gives rise to every cell type in the human body, from neurons to bone, a feat that has fascinated biologists for more than a century. Embryonic stem cells retain much of that original versatility, capable in principle of ②develop into almost any tissue, which is why researchers have long viewed them as a promising raw material for repairing damaged organs. Because harvesting these cells traditionally required ③destroying a human embryo, the research provoked ethical objections fierce enough to slow funding and legislation in several countries for years. A breakthrough arrived when scientists discovered that ordinary adult skin cells could be ④reprogrammed, through the introduction of a handful of specific genes, into a state resembling embryonic versatility without ever touching an embryo. These induced pluripotent cells have not entirely erased the ethical debate, but they have opened a path for stem cell research that far more scientists and funding agencies are willing ⑤to support.

Standard economic theory assumes that money is fungible, meaning that a dollar earned as salary is functionally ①identical to a dollar received as a tax refund or won in a lottery. In practice, however, people routinely sort their finances into separate mental accounts, treating money differently depending on its source or intended purpose. A household that would never dip into its retirement savings to pay for a vacation might nonetheless spend an unexpected bonus on that very trip without ②hesitation, even though both sums are, in strictly financial terms, equally available for either purpose. This ③compartmentalization can produce decisions that appear ④consistent when viewed through a purely rational lens: the same individual who diligently saves a portion of every paycheck may simultaneously carry high-interest credit card debt, effectively paying more to borrow than they earn on their savings. Mental accounting is not always harmful, however; by assigning specific categories to specific funds, individuals can also impose useful ⑤discipline on their spending, preventing money earmarked for essential needs from being diverted toward impulsive purchases.

Hospitals are increasingly adopting artificial intelligence tools that can scan medical images and flag potential tumors ①faster and, in some trials, more accurately than experienced radiologists. Patients understandably welcome any technology that catches disease earlier, yet the growing reliance on these tools raises an uncomfortable legal question that hospitals have only begun to address. When an AI system misses a diagnosis that a human doctor would likely have caught, responsibility becomes ②easy to assign. The doctor may argue that they simply trusted a tool the hospital required them to use, the hospital may argue that the software company guaranteed its accuracy, and the software company may argue that no algorithm can be expected to be ③perfect. Until legal systems ④clarify this chain of responsibility, patients harmed by an algorithmic error may find themselves with no clear party to hold ⑤accountable.

Biodegradable plastics have been promoted as a promising solution to plastic waste, since they are designed to decompose into natural substances rather than persist for centuries. Manufacturers derive these materials from renewable resources such as corn starch, blending them with additives that accelerate microbial breakdown once discarded. However, _______________. For example, a bag labeled biodegradable may take years, not the weeks advertised, to break down in a landfill or ocean, where temperature and microbial activity remain low. In addition, when mixed with conventional plastics in recycling streams, they can contaminate the process, weakening the quality of materials produced afterward. Some engineers therefore compare biodegradable plastics to a bridge that leads nowhere unless paired with infrastructure that completes the journey. Ultimately, realizing their genuine potential requires not only technological refinement but also facilities capable of providing the precise conditions decomposition demands.

When sociologist Émile Durkheim studied suicide rates across different societies, he noticed something puzzling: rates rose not only during economic depression but also during sudden prosperity. He concluded that both crises share a common feature, the collapse of shared norms that once told individuals what to expect and how to behave. Decades later, Robert Merton extended the concept to explain deviance within stable societies, proposing that anomie also arises when a culture insists that everyone pursue identical goals, such as wealth, while denying many people the legitimate means to achieve them. Faced with this gap between aspiration and opportunity, _______________. Anomie theory therefore suggests that crime is less a product of individual failure than of structural imbalance within society itself.

As cities have expanded across landscapes once covered with absorbent soil, impervious surfaces have turned stormwater from a resource that recharges groundwater into a hazard that floods streets and carries pollutants into waterways. Green infrastructure, which mimics the hydrological functions that natural landscapes once performed, offers planners _______________. Rain gardens, shallow depressions planted with deep-rooted vegetation, are designed to capture runoff from rooftops, allowing it to filter slowly through soil before reaching underground aquifers. Permeable pavement, made of porous materials that let water pass directly through, serves a similar purpose along sidewalks, where asphalt would remain impenetrable. For example, cities that replaced pavement with permeable alternatives have reported notable reductions in flooding during storms that once overwhelmed sewers. However, engineers caution that green infrastructure cannot entirely replace conventional pipes in dense cores, where heavy runoff still requires structural reinforcement. Consequently, municipalities now regard green and gray infrastructure as complementary systems, each compensating for the other's limitations.

Financial markets occasionally experience episodes in which asset prices rise far beyond any level that careful analysis of underlying fundamentals could justify, a phenomenon commonly attributed to herd psychology. During such episodes, individual investors often conclude that continuing to buy is reasonable simply because so many others are doing the same, rather than because any independent evaluation supports the purchase. Understanding market bubbles thus requires looking beyond conventional economic fundamentals toward the ___________ that binds individual investors into a single, momentum-driven crowd.

Economists traditionally measured a community's wealth in terms of factories, income, or infrastructure, yet sociologists increasingly point to a less visible resource: social capital, the networks of trust and reciprocity that allow people to cooperate for mutual benefit. (C) However, social capital is not uniformly beneficial; tightly bonded networks can also exclude outsiders and reinforce existing inequality. (B) Communities rich in social capital tend to enjoy lower crime and more effective local government, because neighbors who trust one another can coordinate informally. (A) For this reason, researchers increasingly distinguish between bonding capital, which strengthens ties within a single group, and bridging capital, which connects otherwise separate communities.

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

주어진 문장: Because controlled processing is so resource-intensive, repeated practice offers an efficient way to shift a skill from one category to the other. Cognitive psychologists distinguish between two modes by which the mind handles information, a distinction that helps explain why experienced drivers can hold conversations while navigating familiar roads without conscious effort. ( ① ) Automatic processing occurs rapidly, requires minimal attention, and typically operates outside conscious awareness, allowing multiple automatic tasks to proceed without interfering with one another. ( ② ) Controlled processing, by contrast, unfolds more slowly, demands deliberate attention, and can generally handle only one demanding task at a time, since it draws upon a limited pool of cognitive resources that becomes rapidly depleted under competing demands. ( ③ ) Skills that once required intense concentration, such as reading or typing, gradually become automatic through extensive practice, freeing attentional resources for other purposes. ( ④ ) This shift explains why novice drivers find it difficult to talk while merging onto a highway, whereas seasoned drivers manage the same maneuver with comparative ease. ( ⑤ ) However, automaticity carries hidden costs, since automatized responses can be triggered inappropriately by habitual cues even when circumstances have changed, occasionally producing errors that controlled deliberation would have prevented.
