Philosophers sometimes ask their students to imagine a creature physically ①identically to an ordinary human being in every measurable respect, one that walks, talks, laughs, and even cries out in apparent pain when injured, yet that has no inner conscious experience whatsoever. This imagined being, commonly called a philosophical zombie, ②behaves exactly as a conscious person would, since every neuron fires in precisely the same pattern, but there is supposedly nothing it is like to be that creature from the inside. Defenders of the argument claim that because such a zombie is at least ③conceivable without any logical contradiction, consciousness itself cannot be fully explained by physical processes alone. Critics respond that mere conceivability ④proves very little about what is genuinely possible in the real world, and that our intuition about zombies may simply ⑤reflect the limits of imagination rather than a real gap in nature.

Structural functionalism approaches society as a complex system of ①interdependent parts, each contributing to the overall stability and smooth operation of the whole, much as organs contribute to the survival of a biological body. Sociologist Talcott Parsons argued that institutions such as the family, education, religion, and government each perform necessary functions, socializing new members and transmitting values, so that removing or weakening any one institution ②stabilizes the equilibrium of the entire system. Robert Merton refined this framework by distinguishing manifest functions, the intended and openly recognized consequences of a social practice, from latent functions, ③unintended consequences that nonetheless help sustain the system, such as schools serving not only to educate but also to provide childcare that allows parents to work. Critics have long charged that functionalism, by emphasizing stability and equilibrium, struggles to explain social ④conflict and rapid change, since it tends to interpret persistent inequality as somehow functional for society rather than as a problem requiring ⑤correction.

Engineers are now exploring implants and prosthetics designed to give healthy people abilities beyond ordinary human limits. Supporters frame this as simply the next step in a long history of human enhancement, no different in principle from eyeglasses or vaccines. Critics counter that earlier enhancements were broadly available to anyone regardless of wealth, while cutting-edge neural and physical implants are likely to remain expensive for decades, potentially _______________.

Long before humans learned to drill for oil, microorganisms had already mastered the art of converting sunlight and carbon dioxide into stored chemical energy. Modern biofuel research borrows this ability, cultivating algae or engineered bacteria in large tanks where they can be coaxed into producing oils and sugars that can be refined into fuel usable in existing engines. _______________. 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. 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.

When a country physician named Edward Jenner noticed that milkmaids who had caught cowpox seemed immune to smallpox, he set in motion a medical revolution without fully understanding why it worked. (A) This method produced genuine successes, eventually eliminating smallpox worldwide and reducing diseases such as polio and measles, but each new vaccine still required years of laboratory work with no guarantee of success. (B) Advances in molecular biology eventually allowed researchers to isolate a single protein from a pathogen's surface, producing vaccines with fewer side effects, and the most recent shift toward delivering genetic instructions represents the latest chapter in this story. (C) For nearly two centuries afterward, vaccine development proceeded largely by trial and error, weakening or killing a pathogen and testing whether the resulting preparation could train the immune system without causing disease itself.

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. (A) Skills that once required intense concentration, such as reading or typing, gradually become automatic through extensive practice, freeing attentional resources for other purposes. 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. (B) Automatic processing occurs rapidly, requires minimal attention, and typically operates outside conscious awareness, allowing multiple automatic tasks to proceed without interfering with one another. 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. (C) 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.

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.

Dual coding theory, first proposed to explain why certain kinds of information are remembered more readily than others, holds that the mind processes verbal and visual material through two partially independent channels rather than a single unified system. (A) Consequently, dual coding theory has profound implications for instructional design, suggesting that combining carefully chosen visuals with concise verbal explanations can strengthen students' long-term retention of complex material. (B) According to this account, words and other linguistic symbols are encoded primarily through a verbal channel that represents meaning in an abstract, sequential form, while pictures and concrete objects are encoded through an imagery channel that preserves spatial and perceptual detail. (C) When information engages both channels simultaneously, as when a textbook pairs a written explanation with an accompanying diagram, the resulting memory trace benefits from two separate, mutually reinforcing pathways of retrieval rather than just one. This redundancy explains the well-documented picture superiority effect, whereby concrete, easily visualized words tend to be recalled more accurately than abstract terms that resist mental imagery.

This is, in essence, the working premise of an entire field known as synthetic biology, which treats the living cell as programmable hardware. Imagine rewriting a bacterium's code the way a programmer edits a line of software, and much of what synthetic biology promises begins to make sense. ( ① ) Researchers in this field assemble standardized genetic parts into circuits that can be inserted into a cell. ( ② ) Such circuits can instruct a cell to perform a task that no natural organism would carry out, from glowing under stress to detecting a toxin in water. ( ③ ) Because these circuits are built from interchangeable parts rather than designed from scratch each time, a circuit tested in one lab can often be reused, with minor adjustments, in an entirely different application. ( ④ ) Critics note that biological systems rarely behave as predictably as electronic circuits, since a gene inserted into a new cell can interact with existing pathways in unexpected ways, occasionally producing results no engineer intended. ( ⑤ ) Even so, as the catalog of standardized parts keeps expanding, engineers are gaining confidence to design increasingly complex systems, treating the cell as a chassis onto which new functions can be loaded.

The secret lies not in the cotton plant itself but in a borrowed piece of bacterial DNA. A cotton plant that manufactures its own insecticide sounds like science fiction, yet it has been growing in fields around the world for decades. ( ① ) Scientists achieved this by isolating a gene from a soil bacterium that produces a protein toxic to specific insect pests but harmless to humans. ( ② ) That gene is then inserted into the plant's own genome so that every cell manufactures the protective protein. ( ③ ) Other genetically modified crops carry a gene that allows them to survive direct exposure to a particular herbicide, letting farmers spray a field to kill weeds without harming the crop growing among them. ( ④ ) Supporters point to yield increases and reduced pesticide spraying documented across millions of hectares, while critics worry about weeds and insects evolving resistance to these built-in defenses over time, much as bacteria evolve resistance to antibiotics. ( ⑤ ) Regulatory agencies in most countries now require extensive testing before a genetically modified crop reaches the market, evaluating everything from its nutritional content to its potential effects on nearby ecosystems.
