Suppose a mysterious being with a near-perfect track record of ①predicting human choices presents a player with two boxes. Box A always contains a visible thousand dollars, while Box B contains either a million dollars or nothing at all, depending on a prediction the being made before the game even began. If the being predicted the player would take only Box B, it ②placed a million dollars inside; if it predicted the player would take both boxes, it left Box B empty. The player may choose to take only Box B, or to take both boxes, and the prediction has already ③been made and cannot change. One line of reasoning says taking both boxes is strictly better, since whatever is already inside the boxes cannot ④be altered by the player's choice at this point. A second line of reasoning says taking only Box B is better, since the being's near-perfect accuracy means that choosing both boxes almost ⑤guaranteeing an empty Box B.

Why do people often overvalue objects they have partly ①built themselves, even when the finished product is objectively inferior to something they could have simply purchased? This puzzle, which researchers ②named after a furniture retailer famous for selling items that require home assembly, challenges the standard economic assumption that value is determined solely by an object's inherent qualities. In a series of experiments, participants who ③assembled a plain storage box were willing to pay nearly as much for their own imperfect creation as they were for a professionally built version, despite being fully aware of its flaws. Labor, it seems, functions as a kind of psychological investment: once effort has been ④pour into a task, individuals become reluctant to judge the outcome objectively, because doing so would require admitting that their effort was partly ⑤wasted.

Consider a village green shared freely by every herder in the community, where each individual may graze as many animals as they wish without paying any fee. From the perspective of any single herder, adding one more animal to the shared pasture brings a clear personal ①loss, since the extra income belongs entirely to that herder alone. The cost of the additional grazing, however, is spread thinly across every herder who uses the green, so no single individual bears more than a tiny fraction of the ②damage. Because this calculation favors adding more animals for every rational herder, the shared pasture is gradually ③overgrazed until it can no longer support any animals at all, harming the very community whose rational members caused the collapse. Philosophers use this scenario to illustrate a troubling gap between what benefits an individual in the short term and what preserves a shared resource in the ④long term, a gap that voluntary self-restraint alone rarely ⑤closes.

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 ①understanding why it worked. 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. This method produced ②genuine successes, eventually eliminating smallpox worldwide and reducing diseases such as polio and measles, but each new vaccine still required ③seconds of laboratory work with no guarantee of success. Advances in molecular biology eventually allowed researchers to isolate a single protein from a pathogen's surface rather than using the whole organism, producing vaccines with ④fewer side effects and a more predictable safety profile. The most recent shift, toward delivering genetic instructions rather than proteins themselves, represents the latest chapter in a story that began with an eighteenth-century doctor's curiosity about a ⑤puzzling immunity among dairy workers.

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.

Fairness, in other words, is not a feature that can simply be patched in once a problem is discovered. Many large companies now rely on artificial intelligence to screen job applications before a human ever sees them. ( ① ) These systems promise efficiency, scanning thousands of resumes in seconds and ranking candidates according to patterns drawn from previous hiring decisions. ( ② ) However, this reliance on historical data creates a troubling risk. ( ③ ) If a company's past hiring favored a particular group, the algorithm may learn to treat that pattern as a marker of success and quietly reproduce it, even when no one intended discrimination. ( ④ ) Unlike a human interviewer, the system offers no explanation for its choices, which makes the bias difficult to detect until an outside audit reveals it. ( ⑤ ) Some researchers argue that fairness cannot be added afterward; it must be built into the system's design from the very beginning.

Suppose that one day Mary is finally released from the room and shown a ripe red tomato for the first time. Imagine a brilliant scientist named Mary who has spent her entire life inside a black-and-white room, learning everything physical science could ever teach about color, including the exact wavelengths of light and the precise neural processes triggered when a person sees red. ( ① ) Despite this complete physical knowledge, Mary herself has never actually seen a color; every book, screen, and object in her world has been carefully restricted to shades of gray. ( ② ) Philosopher Frank Jackson argued that Mary would learn something entirely new at that moment, namely what it actually feels like to see red. ( ③ ) This is true even though she already possessed every physical fact about color there was to know beforehand. ( ④ ) If Mary genuinely gains new knowledge upon leaving the room, then physical facts alone cannot capture everything there is to know about conscious experience. ( ⑤ ) Something, it seems, was missing from her exhaustive scientific education all along.

Because the donkey is assumed to be a perfectly rational creature that always chooses the option supported by the strongest reason, it finds itself, in this case, with no rational basis for choosing either pile. Medieval philosophers told the story of a hungry donkey placed exactly midway between two identical, equally fragrant piles of hay, with no factor whatsoever tipping the balance toward either option. ( ① ) Neither pile offers any advantage over the other. ( ② ) Paralyzed by this perfect symmetry, the donkey starves to death precisely because it can find no reason to move in either direction. ( ③ ) Critics of the story point out that real animals, and real humans, rarely face situations of such flawless symmetry. ( ④ ) Even a tiny, arbitrary preference, they note, is usually enough to break the tie in practice. ( ⑤ ) The paradox nevertheless raises a serious question about whether purely rational deliberation can ever generate action on its own.

주어진 문장: This pattern holds regardless of academic subject, suggesting that the depth-of-processing principle generalizes far beyond simple laboratory tasks. For decades, memory researchers assumed that repetition alone determined how well information would be retained, an assumption that an influential theory proposed by Craik and Lockhart eventually overturned. ( ① ) According to their framework, what matters most is not how many times a person rehearses material but how deeply that material is processed during encoding. ( ② ) Shallow processing, which involves attending merely to superficial features such as the shape of letters or the sound of a word, produces memory traces that fade quickly and remain vulnerable to interference. ( ③ ) Elaborative processing, by contrast, requires connecting new information to existing knowledge, generating meaningful associations, and analyzing semantic content, thereby producing traces that are considerably more durable. ( ④ ) Consequently, a student who merely repeats a definition aloud without considering its implications is less likely to retain it than one who relates the concept to a personal example. ( ⑤ ) This distinction reshaped educational practice, encouraging teachers to design tasks that demand comprehension rather than mechanical repetition, since durable memory depends on the depth, not the frequency, of cognitive engagement.

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