As more schools shift toward digital textbooks and online assignments, a student without reliable internet access at home faces a disadvantage that has little to do with talent or effort. During recent years, this gap became impossible to ignore, as families in rural areas or low-income neighborhoods ①struggled to complete schoolwork that assumed a stable connection and a personal device. Some policymakers initially treated internet access as a convenience, comparable to cable television, rather than as infrastructure ②essential to modern life. That assumption is increasingly ③reconsidering, particularly as more essential services, from job applications to medical appointments, move online by default. Closing this divide will require more than simply distributing devices; it will demand sustained investment in the physical networks ④that carry information into every home, ⑤regardless of income or location.

A liver no longer has ①to sit inside a human body to be studied closely. By coaxing stem cells ②organizing themselves within a nutrient-rich gel, scientists can now grow miniature three-dimensional structures called organoids, which reproduce much of the architecture and function of a real organ despite being no larger than a grain of rice. Unlike flat cultures ③grown on a plastic dish, which lose many of the cues that guide normal development, organoids let cells interact in three dimensions much as they would inside the body, yielding tissue ④that behaves in strikingly realistic ways. This fidelity has made organoids invaluable for testing how a drug affects human tissue before any patient is exposed, ⑤sparing researchers much of the burden of relying on animal models alone.

People often recognize, in calm reflection, that their future selves will be tempted to ①abandoning 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 ②known as precommitment. 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 ③arisen. 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 ④resist. Similarly, someone ⑤determined to finish a project might publicly announce a deadline, transforming private intentions into a commitment that carries social consequences if broken.

When an oil tanker ruptures and crude spreads across open water, cleanup crews increasingly reach not only for skimmers and floating booms but also for something far smaller: bacteria that ①eat oil. Certain naturally occurring microbes possess enzymes capable of ②breaking hydrocarbon molecules apart, using the carbon as an energy source and gradually converting a toxic slick into carbon dioxide and harmless byproducts. Bioremediation, as this approach is called, works far more slowly than mechanical cleanup, often ③taking months rather than days, but it can reach contamination trapped in soil or sediment that skimmers and booms can never reach. Scientists have learned to accelerate the process by adding nutrients ④that help native microbial populations multiply faster, or in some cases by introducing engineered strains selected specifically for their appetite for a particular pollutant. Because the method relies on living organisms rather than heavy machinery, it also tends ⑤leave a far gentler footprint on the surrounding ecosystem than excavation or chemical treatment ever could.

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. 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. People do not necessarily fail to understand that the future reward matters more; rather, _______________. 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.

Facing a shortage of caregivers and a rapidly aging population, several countries have begun deploying robots designed to remind elderly residents to take medication and offer simple conversation. Early trials show that many residents report reduced loneliness, particularly when a robot's presence allows a human staff member to spend more time with each patient. Critics, however, worry that _______________, especially in facilities already struggling with tight budgets.

Overconfidence bias is not confined to amateur investors; even seasoned financial professionals display strikingly similar patterns. (A) Fund managers surveyed about the accuracy of their own market predictions, for example, consistently rate their forecasts as more reliable than an objective analysis of their historical track record would support. (B) This gap between perceived and actual accuracy suggests that professional training and experience do not automatically immunize individuals against overconfidence. (C) Some researchers argue instead that professionals may be especially susceptible, since repeated exposure to a domain can breed a false sense of mastery over outcomes that remain fundamentally unpredictable.

주어진 문장: This durability is especially evident in modern debates about whether people can truly perform two demanding tasks at once. Long before cognitive scientists possessed the tools to observe the brain directly, Donald Broadbent proposed an influential model suggesting that the human capacity to process incoming sensory information is constrained by a structural bottleneck through which only a single stream of input can pass at any given instant. ( ① ) According to this filter theory, multiple channels of stimulation, such as competing voices in a crowded room, are initially registered at a shallow, physical level, but only one channel is selected for further, meaning-based analysis while the rest are blocked from advancing beyond that early filter. ( ② ) Although later researchers challenged the rigidity of this early selection mechanism, pointing to instances in which unattended information, such as one's own name, nevertheless breaks through and captures awareness, ( ③ ) the core insight that attention imposes a genuine processing limit rather than a mere matter of willpower has remained remarkably durable. ( ④ ) This basic bottleneck principle continues to inform contemporary explanations of why multitasking so reliably degrades performance on demanding tasks. ( ⑤ )

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.

Confined in this controlled setting, the organisms grow far faster than they ever would in the wild. Long before humans learned to drill for oil, microorganisms had already mastered the art of converting sunlight and carbon dioxide into stored chemical energy. ( ① ) Modern biofuel research borrows this ability, cultivating algae or engineered bacteria in large tanks. ( ② ) There, they can be coaxed into producing oils and sugars that can be refined into fuel usable in existing engines. ( ③ ) Unlike crops grown for corn-based ethanol, which compete directly with food production for arable land, many algae strains can thrive in shallow ponds, wastewater, or even coastal seawater unsuitable for conventional agriculture. ( ④ ) Engineers have also learned to tinker with the metabolic pathways of these organisms, boosting oil yield far beyond what any wild strain would naturally produce on its own. ( ⑤ ) Despite this progress, producing biofuel at a cost competitive with fossil fuel remains difficult, since harvesting and processing the organisms consumes a substantial share of the energy the fuel itself will eventually provide.
