Two patients diagnosed with the same disease and prescribed the same medication can respond in ①strikingly different ways, one recovering quickly while the other experiences little benefit or even harmful side effects. Precision medicine starts from the observation that this variation often traces back to differences buried in each patient's genome, differences that determine how ②efficiently a body absorbs, breaks down, or responds to a given drug. By sequencing a patient's DNA before treatment begins, doctors can increasingly predict which medication is likely to work best and at what dose, replacing a strategy once described as one-size-fits-all with something closer to a ③tailored fit. This approach has proven especially valuable in cancer treatment, where tumors from two patients with the same diagnosis may carry entirely ④identical genetic mutations that respond to entirely different drugs. Widespread adoption still faces real obstacles, since genetic sequencing remains ⑤expensive in many regions and few doctors have been trained to interpret the flood of genetic data such tests now produce.

When an oil tanker ruptures and crude spreads across open water, cleanup crews increasingly reach not only for skimmers and floating booms but also for something far smaller: bacteria that ①eat oil. Certain naturally occurring microbes possess enzymes capable of breaking hydrocarbon molecules apart, using the carbon as an energy source and ②rapidly converting a toxic slick into carbon dioxide and harmless byproducts. Bioremediation, as this approach is called, works far more slowly than mechanical cleanup, often taking months rather than days, but it can reach contamination trapped in soil or sediment that skimmers and booms can never reach. Scientists have learned to ③accelerate the process by adding nutrients that help native microbial populations multiply faster, or in some cases by introducing engineered strains selected specifically for their appetite for a particular pollutant. Because the method relies on living organisms rather than heavy machinery, it also tends to leave a far ④gentler footprint on the surrounding ecosystem than excavation or chemical treatment ⑤ever could.

Behavioral economists have long observed that people tend to feel the pain of losing something more intensely than the pleasure of gaining an equivalent amount, a tendency known as loss aversion. Consider an investor who refuses to sell a declining stock, clinging to the hope that its price will eventually recover, even when all available evidence indicates that selling and reinvesting elsewhere would be more rational. As a result, loss aversion frequently pushes individuals toward ___________ rather than toward the outcome that would maximize their overall welfare.

Conventional economic wisdom holds that more options are always preferable to fewer. Empirical research on consumer behavior, however, complicates this assumption considerably. When shoppers are presented with an extensive array of choices, they frequently experience heightened anxiety about making the wrong selection and, paradoxically, become less likely to make any purchase or decision at all. Businesses that recognize this dynamic have begun deliberately curating smaller, carefully selected assortments, betting that ___________ can sometimes generate more sales and greater customer satisfaction than abundance.

Facial recognition software has moved rapidly from airport security lines into shopping malls, schools, and even private apartment buildings. (A) Independent studies, however, have repeatedly found that many commercial systems perform less accurately on women and people with darker skin tones. (B) Proponents note that the technology can unlock doors, catch shoplifters, and speed up identity checks far faster than any human guard could manage. (C) Several cities have already reported cases in which an innocent person was detained based on a flawed match.

Consider a large heap containing ten thousand grains of sand. (A) Something has clearly gone wrong along the way, since no reasonable person would call one grain of sand a heap, but pinpointing exactly which single removal transformed a heap into a non-heap seems impossible. (B) Nearly everyone agrees that removing a single grain from such a heap leaves another heap behind, since surely one grain could never make the difference between a heap and a non-heap. (C) Yet if this principle is applied repeatedly, grain by grain, the heap eventually shrinks to a single lonely grain, or even to no grains at all, and logic alone seems to force us to accept that this final result still counts as a heap.

Mental accounting also shapes how consumers respond to windfalls of different sizes and origins. (A) A modest windfall, such as a small cash-back reward, tends to be absorbed into everyday spending and disappears almost unnoticed within a household's general budget. (B) A substantial windfall, by contrast, such as an inheritance or a large bonus, is more likely to be mentally assigned to a separate category, sometimes labeled as "extra" money reserved for investment or a significant purchase. (C) This difference in treatment suggests that the perceived significance of a sum, rather than its objective purchasing power, determines the mental account into which it is placed.

주어진 문장: Taken together, these shortcomings suggest that biodegradability alone cannot guarantee a meaningful reduction in plastic pollution. 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. ① Manufacturers derive these materials from renewable resources such as corn starch, blending them with additives that accelerate microbial breakdown once discarded. ② However, their environmental benefits are often exaggerated, largely because decomposition depends on specific conditions rarely found outside industrial composting facilities. ③ 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. ④ In addition, when mixed with conventional plastics in recycling streams, they can contaminate the process, weakening the quality of materials produced afterward. ⑤ 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. ① ② ③ ④ ⑤

주어진 문장: This asymmetry is troubling precisely because, in reality, risk and benefit are often unrelated or even inversely related. When people are asked to judge how risky or beneficial a particular technology is, they rarely conduct anything resembling a careful cost-benefit analysis. ( ① ) Instead, they consult a quick emotional impression, an instinctive sense of whether the technology feels good or feels bad, and let that impression guide their entire judgment. ( ② ) This mental shortcut, known as the affect heuristic, produces a curious pattern that traditional risk theory struggles to explain: activities people like tend to be judged as both safer and more beneficial, while activities they dislike are judged as both riskier and less beneficial, even when no logical relationship between risk and benefit exists. ( ③ ) For example, when researchers presented a fictional industrial chemical alongside a brief description emphasizing its convenience, participants rated it not only as more useful but also, illogically, as less dangerous. ( ④ ) Because emotional impressions form so rapidly and feel so trustworthy, correcting for this heuristic requires deliberate effort; simply presenting more accurate statistics to already anxious or enthusiastic audiences rarely changes their underlying judgment. ( ⑤ )

The label "biodegradable," in other words, can be far more conditional than consumers realize. A plastic bag that fully decomposes within months rather than lingering for centuries sounds almost too convenient to be real, yet certain bioplastics on the market do exactly that under the right conditions. ( ① ) Unlike conventional plastic, derived almost entirely from petroleum, many bioplastics are synthesized from renewable feedstocks such as corn starch or sugarcane, sometimes with the help of bacteria engineered to produce plastic-like polymers as a byproduct of their metabolism. ( ② ) Not every bioplastic biodegrades quickly, however. ( ③ ) Some marketed as eco-friendly break down only in industrial composting facilities that reach conditions rarely found in a backyard compost heap or the open ocean. ( ④ ) Critics point out that growing crops for bioplastic production can compete with food crops for farmland and water, complicating the assumption that a biological origin automatically makes a material more sustainable. ( ⑤ ) Researchers are now exploring bioplastics made from agricultural waste and algae instead of dedicated crops, hoping to sidestep this competition for land while preserving the benefits that first made bioplastics appealing.
