Imagine two travelers ①preparing for the same trip: one refuses to fly after watching news coverage of a recent plane crash, while the other books a flight without hesitation. Statistically, air travel remains far safer than ②driving the same distance by car, yet vivid, emotionally charged images tend to dominate human judgment more powerfully than dry statistics ever could. This tendency, in which people ③estimate how likely an event is based on how easily examples come to mind rather than on actual data, quietly shapes countless everyday decisions. News broadcasts that repeatedly feature rare disasters can leave viewers ④convinced that such events are common, even though official records clearly show the opposite. Advertisers and politicians alike exploit this pattern, knowing that a single striking anecdote often ⑤persuade audiences more effectively than pages of careful statistics ever manage to.

Two drivers, equally distracted by their phones, run a red light in exactly the same careless manner. By pure chance, a child happens to be crossing the street in front of one driver but not the other; the first driver kills the child, while the second driver drives through safely and never even notices the danger. Although both drivers behaved ①identically and made exactly the same reckless choice, society judges them very differently: one faces criminal charges and lifelong guilt, while the other receives, at most, a minor traffic ticket. Philosophers call this troubling ②asymmetry moral luck, since factors entirely outside a person's control end up determining how severely we judge their moral character. If moral responsibility is supposed to ③depend heavily on luck and circumstance rather than on what a person chooses and intends, this outcome seems deeply unfair, yet few people are willing to excuse the unlucky driver as if nothing worse had happened. Moral luck suggests that our everyday judgments rest on a foundation far ④shakier than we usually like to admit, a fact many find genuinely ⑤unsettling.

Long before calculus existed, the Greek philosopher Zeno constructed a series of paradoxes designed to show that motion itself might be logically ①impossible. In one version, a swift runner named Achilles races a slow-moving tortoise that is given a modest head start. Common sense insists that Achilles will quickly ②overtake the tortoise, yet Zeno's argument suggests otherwise. By the time Achilles reaches the tortoise's starting point, the tortoise has crawled a little further ahead, and this process repeats endlessly, generating an infinite number of ③smaller and smaller gaps that Achilles must apparently cross one after another. Zeno concluded that Achilles could never actually catch the tortoise, a conclusion that plainly ④contradicts everyday experience. Modern mathematics eventually resolved the paradox by showing that an infinite series of shrinking distances can still sum to a finite total, ⑤preventing motion from ever being completed in a finite amount of time.

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.

For decades, most vaccines worked by injecting a weakened or inactivated version of a pathogen, coaxing the immune system into recognizing an enemy it had never fought. mRNA vaccines take a different route, delivering a short genetic instruction wrapped in a protective lipid capsule, one that tells the body's own cells how to manufacture a harmless piece of a virus's outer surface protein. Once those cells display the fragment, the immune system learns to recognize it as foreign and builds a defense, without ever having encountered the actual pathogen. Because the vaccine contains no live virus and cannot alter a cell's own DNA, _______________. This speed, first proven on a global scale during a recent pandemic, has convinced many researchers that the same platform could eventually be adapted to fight diseases far beyond infectious illness.

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.

Two patients diagnosed with the same disease and prescribed the same medication can respond in strikingly different ways, one recovering quickly while the other experiences little benefit or even harmful side effects. (A) This approach has proven especially valuable in cancer treatment, where tumors from two patients with the same diagnosis may carry entirely different genetic mutations that respond to entirely different drugs, though widespread adoption still faces real obstacles, since genetic sequencing remains expensive in many regions. (B) 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 tailored fit. (C) Precision medicine starts from the observation that this variation often traces back to differences buried in each patient's genome, differences that determine how efficiently a body absorbs, breaks down, or responds to a given drug.

주어진 문장: Such consistency across repeated trials suggests that the pattern is a genuine feature of human cognition, not random noise. In a classic experiment inspired by Keynes's beauty contest analogy, participants choose a number between zero and one hundred, and the winner is whoever selects the number closest to two-thirds of the average of all guesses submitted. ( ① ) A perfectly rational player, assuming every other participant reasons with unlimited depth, would conclude the equilibrium number is zero, since reasoning about others' reasoning collapses the average toward that single point. ( ② ) In practice, however, actual guesses rarely converge on zero; most participants stop reasoning after a round or two of imagining what others might guess, producing average guesses that cluster between twenty and thirty-five. ( ③ ) This gap between theoretical equilibrium and observed behavior reveals that human reasoning is bounded, capable of anticipating a few steps ahead but rarely capable of iterating the process indefinitely. ( ④ ) Economists use this game as a diagnostic tool, since the number a person submits reveals how many levels of strategic thinking that person is willing to perform. ( ⑤ ) This is a measure that idealized rational agents could never provide.

주어진 문장: The first of these, often called System 1, operates beneath conscious awareness, shaping judgments before a person even realizes a decision is being made. Psychologists studying human judgment often describe the mind as operating through two distinct systems rather than a single unified process. ( ① ) System 1 works quickly and automatically, generating impressions and snap judgments without any noticeable sense of effort, much as a driver instinctively brakes when a ball suddenly rolls into the street. ( ② ) System 2, by contrast, is slow, deliberate, and demanding, engaged only when a problem requires careful calculation or conscious reasoning. ( ③ ) Most daily decisions are handled almost entirely by System 1, which allows people to function efficiently without exhausting their limited mental resources. ( ④ ) This efficiency comes at a cost, however, because System 1 relies on simple shortcuts that can produce systematic errors, and System 2 is frequently too lazy or too occupied to double-check them. ( ⑤ )

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