Bacteria have been cutting up invading viral DNA for billions of years, long before any scientist ①thought to borrow the trick for use in a laboratory. The CRISPR-Cas9 system, as it is now known, relies on a short guide RNA that matches a specific DNA sequence, ②lead a scissor-like enzyme called Cas9 directly to that exact location in the genome. Once Cas9 arrives at the target site, it slices both strands of the DNA helix, and the cell's own repair machinery rushes in ③to mend the cut, often introducing a small change in the process. By supplying the cell with a template during this repair step, scientists can direct that machinery ④to insert a specific new sequence rather than merely disabling the original gene. What once required years of painstaking work to alter a single gene can now, with a properly designed guide RNA, ⑤be accomplished within days, a shift in speed that has reshaped nearly every corner of biological research.

Philosopher Robert Nozick asked his readers ①to imagine a machine capable of producing any experience they desired, from writing a great novel to falling in love, all indistinguishable from reality once they were plugged in. Neuroscientists would simply stimulate the brain to generate a lifetime of perfectly satisfying experiences, and the person floating in the tank would have no memory of ever ②choose to enter it. If pleasure and the avoidance of pain were truly all that mattered, as classical hedonism claims, then everyone ③should rush to connect themselves permanently to such a machine. Yet when people actually consider the offer, most hesitate, and many refuse outright. Nozick took this reluctance as evidence ④that human beings care about more than the quality of their internal sensations. People also want to actually be a certain kind of person, and to ⑤maintain genuine contact with a reality beyond their own mind.

Suppose you meet a quiet, gentle man ①who speaks softly, tends a small garden, and organizes his bookshelf with meticulous care. ②Ask whether he is more likely a florist or a truck driver, most people instinctively choose florist, since his personality matches the stereotype so neatly. This judgment, however, ③ignores a crucial fact: truck drivers vastly outnumber florists in almost every country, which means that, statistically, he is far more likely to belong to the larger group regardless of how well he fits the flower-shop image. Relying on resemblance to a familiar category rather than on underlying numerical proportions, ④known among researchers as representativeness, leads people to overlook these base rates almost automatically. Even trained professionals, ⑤who should know better, often fall into the same trap when a vivid description feels more convincing than plain statistics.

When people look back on a multi-day journey, they rarely ①recall every hour with equal clarity; instead, memory tends to compress the entire experience into just a few representative moments. Psychologists have found that two points carry disproportionate weight in this process: the single moment when emotion, whether joy or discomfort, ②reached its highest intensity, and whatever happened right before the experience concluded. Consider two hikers who complete an identical five-day trek. The first finishes with a grueling, rain-soaked final climb, while the second enjoys a calm, scenic descent on the last afternoon despite having ③endure an equally difficult ascent earlier in the trip. Even though both hikers faced comparable hardship overall, the second is far more likely to remember the journey fondly, simply because the trip ④ended pleasantly. This pattern reveals that overall satisfaction is not calculated as an average of every experienced moment; rather, it is shaped disproportionately by whichever moments ⑤felt most intense and by however the experience happened to end.

Physicist Erwin Schrödinger devised a now-famous thought experiment not to describe an actual laboratory procedure, but ①to expose an absurdity hidden within a leading interpretation of quantum mechanics. Imagine a cat sealed inside a closed box together with a radioactive atom, a Geiger counter, and a vial of poison gas ②rigged to break open the instant the atom decays. Because the atom's decay is governed by genuine quantum randomness, standard quantum theory describes the atom, before anyone looks, ③as existing in a superposition of having decayed and not having decayed at the same time. If the theory is applied consistently to the entire box, the cat itself would have to ④be considered simultaneously alive and dead until an observer opens the lid and looks inside. Schrödinger intended this image to sound obviously ridiculous, using the cat's absurd fate to question whether the act of observation truly determines physical reality, or whether the mathematics is simply being pushed further than it ⑤ever meaning to go.

The ancient puzzle known as the ship of Theseus asks a deceptively ①simple question. If every plank of a wooden ship is replaced one by one over many years, is the vessel that eventually results still the same ship it once was? Most people's first instinct is to answer yes, since each individual replacement seems too ②small to erase the ship's identity. The puzzle grows far ③duller, however, once a second twist is introduced. Suppose a careful collector gathered every discarded plank and reassembled them into a second vessel, built exactly as the original once stood. Two ships would then exist side by side, each with an equal claim to being the ④genuine one, and no obvious way to decide between them. Philosophers return to this old story again and again, not because they care about timber, but because it forces us to ask whether identity depends on continuous material, continuous form, or some deeper thread that neither one can fully ⑤explain.

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.

Few ideas in policy debate provoke as much philosophical unease as the notion that a government might deliberately steer citizens toward better choices while leaving every option technically available. Defenders insist that freedom is preserved as long as no option is banned and no penalty is attached. Critics counter that this defense rests on an impoverished notion of liberty, one that ignores how _______________. The dispute ultimately turns on what freedom actually requires: the mere absence of coercion, or a decision-making process that remains transparent and undistorted.

주어진 문장: This buying and selling of allowances effectively creates a market price for carbon, one that fluctuates according to how difficult reduction proves across different industries. Emissions trading, a market-based mechanism for curbing greenhouse gases, allows governments to set an overall limit on carbon output while letting firms trade permits within that limit. ① Under this system, known as cap-and-trade, companies that cut emissions more cheaply than required can sell surplus allowances to firms facing higher reduction costs. ② Proponents argue that this flexibility lets society reach a given environmental target at the lowest overall cost, since abatement shifts toward whoever can achieve it most economically. ③ Critics, however, contend that trading schemes frequently allocate too many permits, a flaw that has historically depressed carbon prices and blunted incentives to invest in cleaner technology. ④ For example, early phases of several regional markets granted allowances so generously that permit prices collapsed, leaving polluters with little pressure to change their practices. ⑤ Consequently, many economists now advocate combining trading with a price floor, a minimum permit price that keeps the market from collapsing during weak demand, thereby preserving the cost-effectiveness for which trading is valued. ① ② ③ ④ ⑤

주어진 문장: Her plan, however sincere at the time, quietly dissolves the moment a more immediate temptation appears. Consider a student who genuinely intends to study for tomorrow's exam yet, when the evening actually arrives, chooses to watch another episode of a favorite show instead, promising herself she will surely study harder next week. ( ① ) This pattern, in which the pull of an immediate pleasure overwhelms the value of a distant benefit, appears again and again across ordinary life, from postponed exercise to delayed savings. ( ② ) People do not necessarily fail to understand that the future reward matters more; rather, whatever happens right now simply feels disproportionately more urgent and vivid than anything scheduled for later. ( ③ ) Behavioral economists note that this preference weakens considerably once both options are pushed into the future, which is why planning a diet starting next month feels effortless compared with skipping dessert tonight. ( ④ ) Such inconsistency helps explain why gym memberships go unused and retirement accounts remain underfunded, despite people's stated intentions. ( ⑤ ) Recognizing this pull toward the present, therefore, allows individuals and institutions to design commitments that quietly protect long-term goals from short-term temptation.
