Blockchain technology was originally promoted as a way ①to remove the need for trusted middlemen, allowing strangers to exchange value directly and verify transactions through a shared, tamper-resistant ledger rather than through a bank or government agency. In theory, this design ②distributes power away from any single institution and toward the network as a whole. In practice, however, a small number of large players have come to dominate many blockchain networks, ③controlled enough computing power or currency to influence outcomes that were supposed to be decided collectively. Critics note a further irony: when something goes wrong, there is often no institution left ④to appeal to, since the entire system was designed precisely to eliminate that kind of central authority. Whether decentralization can survive this concentration of power ⑤remains one of the technology's most unresolved questions.

Many households save far less for retirement than conventional financial advice would recommend, not necessarily because they ①lacks the resources to do so, but because a combination of procrastination, present bias, and the discomfort of forgoing current consumption repeatedly delays the decision to begin saving. Recognizing this gap between intention and action, some economists have proposed a savings program in which employees commit today to ②allocating a portion of their future salary increases toward retirement savings, rather than being asked to reduce their current take-home pay immediately. Because the sacrifice applies only to income not yet received, the commitment ③feels far less painful than an equivalent reduction in present earnings would, making employees considerably more willing to enroll. Once enrolled, the contribution rate automatically rises with each subsequent raise, ④gradually increasing savings without requiring any further deliberate action from participants. Field trials of such programs have reported substantial increases in average savings rates over several years, alongside participant satisfaction that ⑤remains notably high.

As more businesses move their operations online, cyberattacks have become one of the most ①serious threats facing modern companies. In response, demand for cybersecurity professionals has ②decreased across nearly every industry. These specialists design systems that detect suspicious activity, patch vulnerabilities before criminals can exploit them, and train employees to recognize phishing attempts. Unlike many technical fields, cybersecurity requires constant learning, since hackers continually develop new methods to ③bypass existing defenses. Despite this expansion, experts estimate that millions of cybersecurity positions worldwide remain ④unfilled, largely because the number of qualified applicants has not kept pace with rapidly increasing demand. This shortage suggests that cybersecurity will remain a ⑤promising career path for years to come.

Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. This theory explains that every habit begins with a cue, a signal that tells the brain to start an automatic behavior. The brain then performs a routine, which is the action itself, whether physical or mental. Finally, the brain receives a reward, a positive feeling that makes it want to repeat the same behavior. For example, a notification sound can act as a cue that leads a student to check a phone, and the relief from boredom becomes the reward. Similarly, opening a refrigerator out of habit rather than hunger shows how a routine can run without conscious thought. Because this loop operates automatically, breaking a bad habit requires ___________. Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.

Military researchers have developed weapons systems capable of identifying and engaging targets without a human pressing the final button. Advocates argue that autonomous systems can react faster than any human operator. Human rights organizations counter that removing a person from the final decision strips away moral responsibility, since _______________. Diplomatic negotiations toward an international treaty have repeatedly stalled, partly because military powers disagree on how to define autonomy precisely enough to regulate it.

My first attempt at a summer schedule failed because it was much too strict. (A) I also began leaving one day each week completely free for rest or spontaneous activities. (B) My older sister suggested setting just two or three main goals for each day instead. (C) Since making these changes, I have been able to follow my schedule much more consistently.

주어진 문장: This distinction between merely sensing a stimulus and truly perceiving it matters far beyond the psychology laboratory. It would be comforting to believe that anything sufficiently large or obvious appearing within our field of vision will automatically capture our attention, yet decades of research into inattentional blindness suggest otherwise. ( ① ) When people are absorbed in a demanding task, such as counting how many times a ball is passed between players, they frequently fail to notice an unexpected and conspicuous event unfolding in plain sight, even something as unlikely as a person in a costume walking through the scene. ( ② ) This failure does not stem from a defect in the eyes, which register the stimulus perfectly well, but from the fact that conscious perception depends heavily on where attention has been directed. ( ③ ) Policymakers ought to take this finding more seriously than they currently do, because it implies that simply placing a warning sign within someone's visual range offers no guarantee that it will be consciously registered. ( ④ ) Designing safer environments, therefore, requires accounting for the limits of attention itself, not merely assuming that visibility alone ensures awareness. ( ⑤ )

주어진 문장: Unlike traditional employees, these workers are typically classified as independent contractors. The gig economy, in which people take on short-term or freelance jobs instead of full-time positions, has grown rapidly over the past decade. Digital platforms now connect customers directly with drivers, designers, writers, and countless other independent workers within minutes. ( ① ) This model offers clear advantages: workers can choose when and how much they work, and businesses can hire help only when they actually need it. ( ② ) For many young people entering the job market, gig work provides valuable flexibility that traditional employment rarely allows. ( ③ ) However, gig workers often lack benefits such as health insurance, paid leave, and retirement savings, which full-time employees typically receive. ( ④ ) Because their income can fluctuate sharply from month to month, many gig workers struggle to plan their finances confidently. ( ⑤ ) As this sector continues to expand, governments face growing pressure to design policies that protect independent workers.

The software company, in turn, may argue that no algorithm can be expected to be perfect. Hospitals are increasingly adopting artificial intelligence tools that can scan medical images and flag potential tumors faster than experienced radiologists. ( ① ) When an AI system misses a diagnosis that a human doctor would likely have caught, responsibility becomes difficult to assign. ( ② ) The doctor may argue that they simply trusted a tool the hospital required them to use. ( ③ ) The hospital, meanwhile, may argue that the software company guaranteed its accuracy. ( ④ ) Until legal systems clarify this chain of responsibility, patients harmed by an algorithmic error may find themselves with no clear party to hold accountable. ( ⑤ )

In other words, people want the safest outcome for society in theory, but the safest outcome for themselves in practice. When engineers design the software that controls a self-driving car, they inevitably face a question that philosophers have debated for decades. ( ① ) If a crash becomes unavoidable, should the vehicle protect its own passenger at all costs, or should it be programmed to minimize total harm, even if that means steering toward the person inside? ( ② ) Surveys reveal an uncomfortable contradiction: most people say a car should be programmed to save the greater number of lives. ( ③ ) Yet the same people admit they would never buy a vehicle designed to sacrifice its own owner. ( ④ ) This gap between the ideal and the personal choice suggests that ethical programming cannot be settled by public opinion alone. ( ⑤ ) Manufacturers, regulators, and philosophers must instead agree on transparent rules before autonomous vehicles are allowed to make such decisions.
