Blockchain technology was originally promoted as a way to remove the need for trusted middlemen, allowing strangers to exchange value directly and verify transactions through a shared, ①tamper-resistant ledger rather than through a bank or government agency. In theory, this design distributes 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 ②dominate many blockchain networks, controlling enough computing power or currency to influence outcomes that were supposed to be decided collectively. Critics note a further irony: when something goes wrong, such as a hacked exchange or a lost password, there is often ③ample institutional support to appeal to, since the entire system was designed precisely to eliminate that kind of central authority. Whether decentralization can ④survive this concentration of power remains one of the technology's most ⑤unresolved questions.

Behavioral economists use the term temporal discounting to describe how people ①undervalue future rewards simply because those rewards are not immediate. This tendency explains why a student might choose to watch videos tonight rather than study for an exam that remains several weeks away, even though studying offers a ②smaller long-term benefit. A distant reward, no matter how valuable, feels psychologically smaller than a small reward available right now. This bias contributes to procrastination, since future consequences rarely feel ③urgent enough to motivate immediate action. To counter this tendency, students should ④convert distant goals into smaller, near-term milestones that feel more emotionally real. Setting weekly checkpoints rather than a final deadline can make future benefits feel ⑤closer and more concrete.

A cluster of neurons smaller than a pea can now spontaneously organize itself into layered structures that mimic, in miniature, the architecture of a developing human brain. Grown from stem cells coaxed to follow the same developmental cues that guide an embryo, these brain organoids have begun firing electrical signals in patterns that faintly resemble the activity recorded in an infant's brain. For researchers studying disorders such as autism or schizophrenia, this offers something long unavailable: a living model of human brain development that can be observed and manipulated directly, without ever touching an actual patient. Because organoids lack sensory organs, a body, or any connection to the outside world, most neuroscientists argue that the structures cannot generate anything resembling subjective experience, however brain-like their electrical activity may appear. _______________.

Engineers are now exploring implants and prosthetics designed to give healthy people abilities beyond ordinary human limits. Supporters frame this as simply the next step in a long history of human enhancement, no different in principle from eyeglasses or vaccines. Critics counter that earlier enhancements were broadly available to anyone regardless of wealth, while cutting-edge neural and physical implants are likely to remain expensive for decades, potentially _______________.

The rise of autonomous vehicles has created both excitement and anxiety within the transportation industry. (A) In particular, long-distance trucking jobs are expected to shrink significantly as autonomous trucks become more common on highways. (B) At the same time, entirely new positions are emerging, such as remote operators who monitor fleets of self-driving vehicles from control centers. (C) On one hand, many professional drivers fear that automation will eliminate the jobs they currently depend on.

Goal-setting theory has influenced not only classrooms but also workplaces around the world. (A) Many companies now train managers to set specific quarterly targets rather than simply asking employees to 'do their best.' (B) As a result, employees often report clearer priorities and a stronger sense of accomplishment. (C) These targets typically include measurable numbers, such as sales figures or project deadlines.

Ego depletion theory has sparked considerable debate among psychologists studying self-control. (A) One well-known experiment asked participants to resist eating fresh cookies while a bowl of radishes sat nearby, and these participants later gave up more quickly on a difficult puzzle. (B) The theory originally proposed that resisting temptation consumes a limited mental resource, leaving less energy available for subsequent tasks. (C) Researchers interpreted this result as evidence that resisting the cookies had drained the mental resource needed to persist on the puzzle.

주어진 문장: This small success, in turn, created enough momentum that stopping suddenly felt more difficult than continuing. Jian wanted to become a reader for years, but every time he picked up a thick novel, he felt overwhelmed and quickly closed it. ( ① ) His cousin, who had read dozens of books that year, told him about something called the two-minute rule. ( ② ) This rule states that a new habit should be shrunk to under two minutes, since a smaller starting point removes the friction that usually stops people from beginning. ( ③ ) Instead of committing to a full chapter each night, Jian promised himself only to open a book and read one page. ( ④ ) Some nights he stopped after that single page, but most nights, once started, he kept reading for twenty or thirty minutes without noticing. ( ⑤ ) Because the initial barrier became so small, sitting down no longer felt like a burden requiring willpower. Within three months, Jian had finished five books, proving that reducing friction can matter more than motivation itself.

주어진 문장: In other words, the promised environmental benefit is far less certain than it first appears. To compensate for their carbon emissions, many individuals and companies now purchase carbon offsets, financial credits that fund projects such as planting trees or building renewable energy plants. ( ① ) The idea is appealing: paying for an equivalent amount of carbon to be absorbed elsewhere should cancel out the harm caused by activities like flying. ( ② ) However, critics argue that this system often functions as a convenient excuse for postponing genuine emission cuts rather than achieving them. ( ③ ) For example, a newly planted forest may take decades to absorb the promised carbon, and it could later burn down or be cut, erasing any benefit. ( ④ ) Moreover, some offset projects would have happened anyway, meaning the credits fund nothing truly additional. ( ⑤ ) Therefore, relying heavily on offsets allows businesses to maintain harmful practices while appearing responsible. Experts insist that offsetting should complement, not replace, direct reductions in fossil fuel use if the strategy is to remain credible.

주어진 문장: Creating a convincing avatar, in other words, is far more complex than simply choosing a picture. The metaverse, a network of interconnected virtual worlds, has begun to generate job opportunities that did not exist just a few years ago. ( ① ) Companies now hire virtual world designers who build digital environments where users can socialize, shop, or attend events. Avatar designers create digital identities that represent users within these spaces, blending artistic skill with technical programming knowledge. ( ② ) Meanwhile, virtual event planners organize concerts, conferences, and product launches entirely within online platforms, reaching audiences that would be impossible to gather in person. ( ③ ) Some analysts remain skeptical, pointing out that the metaverse has not yet attracted the massive user base that early predictions promised. ( ④ ) Nevertheless, major companies continue investing heavily in this technology. ( ⑤ ) For students considering future careers, gaining skills in three-dimensional design and coding may prove valuable.
