Imagine a teleportation device that scans every atom in your body, transmits that information to a distant station, and reconstructs an exact physical duplicate there, while destroying the original body in the process. From the traveler's point of view, stepping into the machine and stepping out on the other side would feel utterly ①seamless, complete with continuous memories and a sense of having simply walked through a door. Philosophers, however, are troubled by a version of the same device that malfunctions: instead of destroying the original, it leaves the original body intact while still creating a perfect duplicate elsewhere. Now two people exist, each with ②identical memories and an equally strong claim to being the original traveler, and there is ③a clear and principled way to say that one of them is the real continuation of the person who entered the machine. This malfunction reveals that memory and psychological continuity alone cannot fully ④settle what personal identity actually requires, a puzzle that remains ⑤unresolved to this day.

Imagine rewriting a bacterium's code the way a programmer edits a line of software, and much of what synthetic biology ①promises begins to make sense. Researchers in this field assemble standardized genetic parts into circuits that can be inserted into a cell, instructing it to perform a task that no natural organism would ②carry out. 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 ③minor adjustments, in an entirely different application. Critics note that biological systems ④always 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. Even so, as the catalog of standardized parts keeps expanding, engineers are gaining ⑤confidence to design increasingly complex systems.

Philosophers often pair the classic trolley problem with a companion case designed to test whether our moral intuitions are actually ①consistent. Imagine a brilliant surgeon who has five patients, each dying from the failure of a different organ, and one healthy visitor in the waiting room whose organs happen to be a perfect ②match for all five. If the surgeon secretly killed the healthy visitor and transplanted the organs, five lives would be saved at the cost of one, exactly the same arithmetic used to justify diverting a runaway trolley onto a track with a single worker. Yet almost everyone who accepts the trolley diversion ③recoils immediately at the idea of the surgeon cutting up an unwilling patient, even though the numbers are identical in both cases. Philosophers use this contrast to argue that outcomes alone can ④fully explain our moral judgments, since something about directly using a person's body as a mere means appears to matter deeply to most people's sense of ⑤right and wrong.

A striking proportion of individual investors believe their own stock-picking ability to be above average, a statistical impossibility given that only half of any population can genuinely outperform the rest. This tendency, known as overconfidence bias, leads investors to trade more frequently than a more cautious assessment of their own skill would justify. Paradoxically, then, the very confidence that motivates investors to act decisively often undermines the outcomes they are trying to achieve, since ___________ frequently produces worse results than a more modest, diversified strategy.

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. A perfectly rational player, assuming every other participant reasons with unlimited depth, would conclude the equilibrium number is zero. 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 _______________. This gap between theoretical equilibrium and observed behavior reveals that human reasoning is bounded.

Labeling theory approaches deviance not as a fixed property of certain acts, but as a social process created when powerful groups attach a negative label to a person's behavior. According to this view, nearly everyone breaks minor rules at some point, yet only some individuals are singled out, caught, and formally branded as delinquents or criminals. Sociologist Howard Becker argued that this label often becomes a master status, a single identity that overshadows every other trait a person has. Once labeled, an individual may find legitimate opportunities closing off, pushing them toward _______________. This process, sometimes called secondary deviance, illustrates how social reaction can produce the outcome it claims merely to describe.

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. (A) 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. (B) 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. (C) Manufacturers derive these materials from renewable resources such as corn starch, blending them with additives that accelerate microbial breakdown once discarded. However, their environmental benefits are often exaggerated, largely because decomposition depends on specific conditions rarely found outside industrial composting facilities.

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. (A) 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. (B) By supplying the cell with a template during this repair step, scientists can direct that machinery to insert a specific new sequence, and what once required years of painstaking work to alter a single gene can now be accomplished within days. (C) 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.

The human gut hosts trillions of microorganisms whose combined genetic material outnumbers that of the human genome itself many times over. (A) A microbiome disrupted by antibiotics, poor diet, or chronic stress can leave the gut lining more permeable than it should be, allowing substances to leak into the bloodstream that would normally stay contained. (B) Once dismissed as passive hitchhikers, these bacteria are now understood to actively shape digestion, regulate immune responses, and even influence the production of chemicals that affect mood and behavior. (C) Researchers studying this connection have found that transplanting gut bacteria from a healthy donor into a patient can relieve symptoms of certain digestive disorders, though the microbiome varies enormously between individuals, so a treatment that helps one person's gut may do little for someone else's.

주어진 문장: The same reflexive shift can occur when a smoke alarm suddenly interrupts a deep conversation, even though no one had been monitoring it consciously. Imagine standing at a crowded party where dozens of conversations blend into a wall of noise, yet you effortlessly track the words of the friend beside you. ( ① ) Curiously, if someone across the room utters your name, your attention snaps toward that voice almost instantly. ( ② ) This happens even though you had not consciously been listening to that conversation at all. This phenomenon, known as the cocktail party effect, reveals that selective attention does not simply block out every unattended sound. ( ③ ) Early theorists such as Donald Broadbent proposed that unattended information is filtered out entirely before reaching awareness. Yet the fact that a person's own name can break through this filter contradicts such a rigid model. ( ④ ) Anne Treisman later refined this account, suggesting that unattended channels are merely attenuated rather than eliminated altogether. Especially meaningful stimuli, including one's own name, can still surpass the threshold of conscious recognition. ( ⑤ ) This refinement suggests that attention operates less like a gate and more like a dimmer switch, adjusting the salience of competing streams of information.
