Working memory refers to the mental workspace in which information ①is temporarily held and manipulated while a person performs a cognitive task. Such tasks include solving an arithmetic problem, following a rapid conversation, or holding a phone number in mind before dialing it. In the mid-twentieth century, the psychologist George Miller proposed that this workspace could accommodate roughly seven discrete items. His claim proved so influential that it ②become widely known as the magic number seven. Subsequent research, however, revealed that Miller's estimate was somewhat generous, since it failed to account for the complexity of the material ③being remembered. Nelson Cowan later argued that when rehearsal strategies ④are prevented and attention is tightly controlled, genuine capacity hovers closer to four items rather than seven. This discrepancy suggests that what earlier studies had measured was not raw storage capacity itself but a hybrid quantity ⑤inflated by clever strategies. Contemporary psychologists therefore distinguish between the fixed limit of working memory and the flexible techniques that allow individuals to transcend that limit.

As solar and wind power expand ①rapidly across national grids, engineers face a challenge that receives far less public attention than the construction of the generating facilities themselves. Unlike conventional power plants, which can adjust their output to match demand at almost any moment, solar panels and wind turbines generate electricity only when sunlight or wind is available, producing supply that fluctuates ②rarely. One proposed solution involves large-scale battery storage systems, which absorb ③surplus electricity generated during periods of high output and release it later when generation declines. Another approach relies on expanding transmission networks across wider regions, so that electricity generated in a sunny area can be redirected to places experiencing a ④shortfall. Without such investment, integrating renewable energy could ⑤paradoxically undermine the very reliability that modern electricity grids are expected to provide.

Traditional industrial systems have relied on a linear model of production, in which raw materials are extracted, transformed into goods, and eventually discarded as waste. This approach treats natural resources as if ①unlimited and disposal as if costless. A circular economy proposes an alternative framework in which materials are kept in continuous use through reuse, repair, and recycling, thereby ②reducing the extraction of virgin resources. Central to this model is the notion that waste, rather than being an inevitable byproduct, can be redesigned as a resource for another process, much as fallen leaves nourish the trees that shed them. For example, manufacturers design products so that components can be disassembled and reused in new items once their original function ends. Some companies also lease equipment instead of selling it outright, retaining responsibility for refurbishment. Because such practices lessen dependence on finite raw materials, they ③increase the environmental damage caused by mining. Consequently, the circular economy is increasingly regarded as a ④viable economic strategy that ⑤conserves resources for future generations.

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. Because the donkey is assumed to be a perfectly ①rational creature that always chooses the option supported by the strongest reason, and because neither pile offers any advantage over the other, the donkey supposedly finds itself with no rational basis for choosing one pile rather than the other. ②Paralyzed by this perfect symmetry, the donkey starves to death precisely because it can find no reason to move in either direction. Critics of the story point out that real animals, and real humans, rarely face situations of such flawless symmetry, and that even a tiny, ③arbitrary preference is usually enough to break the tie in practice. The paradox nevertheless raises a serious question about whether purely rational deliberation can ever ④generate action on its own, without some additional nudge that reason alone ⑤willingly supplies.

When people recall precisely where they were and what they were doing at the moment they learned of some momentous public event, the resulting memory often feels extraordinarily vivid, as though it had been etched into the mind with photographic precision; researchers have termed such recollections flashbulb memories. Proponents of this concept once argued that the emotional intensity and surprise accompanying such events trigger a distinct neural mechanism that preserves details with unusual fidelity, effectively exempting them from the gradual decay that afflicts ordinary memories. Subsequent longitudinal studies, however, have complicated this picture considerably: when researchers compared accounts gathered within days of an event to accounts gathered years later, they discovered that details had frequently been altered, omitted, or even fabricated, even though the individuals reporting them expressed unwavering confidence in their accuracy. This persistent mismatch between subjective certainty and objective consistency implies that _______________.

People often recognize, in calm reflection, that their future selves will be tempted to abandon a goal they currently value. Rather than relying solely on willpower at the critical moment, they may choose to restrict their own future options in advance, a strategy known as precommitment. (A) What unites these examples is a simple insight: because future desires cannot always be trusted, the wisest moment to act may be now, while judgment remains clear and temptation has not yet taken hold. (B) By making certain choices costly, inconvenient, or impossible to reverse, individuals can protect a long-term goal from a short-term impulse that has not yet arisen. (C) A person hoping to save money might lock funds into an account that penalizes early withdrawal, removing the very temptation that would otherwise be difficult to resist. Similarly, someone determined to finish a project might publicly announce a deadline, transforming private intentions into a commitment that carries social consequences if broken.

Factories that once employed hundreds of workers on an assembly line now run with a fraction of that staff, as robotic arms handle tasks that used to require human hands. (A) However, critics point out that earlier transitions unfolded over generations, giving workers time to retrain, whereas today's robots are being deployed much faster. (B) Historical evidence offers some comfort: previous waves of automation eventually created new categories of work that no one had predicted. (C) A factory worker displaced this year, therefore, cannot simply wait for a new industry to emerge decades from now.

Scientists have long searched for a way to describe, in a single coherent framework, the outer limits within which human activity can safely continue without destabilizing the planet's fundamental systems. (A) The concept of planetary boundaries, introduced by earth-system researchers, identifies nine interconnected processes, including climate change, biodiversity loss, and nitrogen pollution, each possessing a threshold beyond which abrupt and irreversible change becomes likely. (B) Some philosophers have likened this framework to a ship's safe operating margin, within which passengers may move freely without risking the vessel's stability. Critics, however, contend that the boundaries are drawn with more confidence than the data can support. (C) Unlike conventional environmental limits, often defined locally, these boundaries are framed at a planetary scale, reflecting the idea that the Earth functions as a single interdependent system rather than a collection of isolated regions. Crossing one boundary, proponents argue, does not merely damage the system involved but can also destabilize others, since climate, oceans, and land are bound together by feedback loops that transmit disturbance across the system.

The player may choose to take only Box B, or to take both boxes, and the prediction has already been made and cannot change at this point. Suppose a mysterious being with a near-perfect track record of predicting human choices presents a player with two boxes. ( ① ) 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. ( ② ) If the being predicted the player would take only Box B, it placed a million dollars inside; if it predicted the player would take both boxes, it left Box B empty. ( ③ ) One line of reasoning says taking both boxes is strictly better, since whatever is already inside the boxes cannot be altered by the player's choice. ( ④ ) 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 guarantees an empty Box B. ( ⑤ ) This apparent conflict between two seemingly sound arguments has made the puzzle a lasting challenge for decision theory.

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.
