Blockchain technology was originally promoted as a way ① to 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 ② 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 dominate many blockchain networks, ③ controlled 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 ④ to appeal to, since the entire system was designed precisely to eliminate that kind of central authority. Whether decentralization can survive this concentration of power ⑤ remains one of the technology's most unresolved questions.

Having grown up with smartphones and social media, they research products ①extensively online before making even small purchases. Unlike older generations, who often valued brand loyalty above all else, many members of Generation Z ②prioritize a company's values, switching brands easily if one no longer matches their beliefs. They also tend to ③favor secondhand and resale platforms, viewing sustainability as an important factor. Peer recommendations shared through short videos frequently carry ④less weight than traditional celebrity endorsements, since viewers see these creators as relatable rather than distant figures. Businesses that fail to adapt to these preferences risk losing an entire generation of potential customers, so many companies now invest in ⑤authentic engagement.

The immune system produces an almost limitless variety of antibodies, each shaped to latch onto one particular molecular target with remarkable specificity. Monoclonal antibody drugs harness this natural precision by cloning a single antibody-producing cell in the laboratory, generating an army of identical antibodies built to recognize one target, such as a protein on a cancer cell or a molecule driving an autoimmune disease. _______________. Manufacturing monoclonal antibodies remains far more complicated than producing a conventional small-molecule pill, since living cells must be cultivated in carefully controlled bioreactors for weeks before the antibody can be purified and prepared for use. This complexity keeps monoclonal antibody treatments considerably more expensive than most conventional drugs, a cost that continues to shape debates over pricing and access.

As governments and companies work to address climate change, a new category of employment known as green jobs has expanded rapidly. Critics point out that transitioning workers from fossil fuel industries to green jobs is not always simple, since the required skills can differ significantly. Governments are therefore introducing training programs designed to help such workers shift smoothly into renewable energy careers. As climate goals become more urgent worldwide, ___________.

Dear members of the Debate Club, I am writing to let you know that our regular meeting time has been changed. (A) Please bring the debate topic that you prepared last week, since we will practice our arguments together. If you cannot attend the new meeting time, please reply to this email by Tuesday evening. (B) We usually meet in Room 304 every Wednesday after school, but the room will be used for sports day practice next week. Instead, our meeting will be held in the library on Thursday at the same time. (C) We also need two volunteers to arrange the chairs and tables before the meeting begins. Mr. Park, our club advisor, will join us this time to give feedback on our speaking skills. Thank you for your understanding, and I look forward to seeing everyone on Thursday.

Most students only see the final result, a few smooth minutes each morning. Behind that short program, however, broadcasting club members follow a busy daily routine. (A) At exactly eight o'clock, the red light turns on, and the live broadcast begins. During class hours, however, most members return to their regular classroom lessons like everyone else. (B) Members arrive at school thirty minutes earlier than other students to prepare the studio. They check the microphones, the cameras, and the lighting before anyone else arrives. Meanwhile, the script team finalizes the news script that was written the night before. Once everything is ready, the anchors practice their lines one last time. (C) After school, the club meets again to review that morning's recording and discuss any mistakes. Through this daily routine, members slowly learn skills such as teamwork and quick thinking under pressure.

Part-time jobs can teach students skills that go far beyond earning money. (A) In contrast, employees who ignore mistakes or blame others often struggle to keep their jobs. (B) Workers who stay calm and take responsibility for errors tend to earn their coworkers' trust. (C) For example, handling a customer complaint well can be a valuable lesson in patience and communication.

주어진 문장: No experience is necessary, so anyone who cares about nature is welcome to join. Good afternoon, everyone! Our town invites students to join a special tree-planting volunteer day next month. ① This event aims to restore a small forest damaged by last year's fire near the river. ② Volunteers will meet at the community center at nine in the morning and travel together by bus. Please wear old clothes and shoes that you do not mind getting dirty during the activity. ③ Each participant will plant three young trees, guided by experienced forest rangers throughout the morning. For example, rangers will show volunteers how to dig proper holes without harming the tree roots. ④ In contrast, planting too shallowly often causes young trees to die within a few months. Therefore, careful instructions must be followed closely by every volunteer. ⑤ Water and snacks, prepared by the town office, will be provided for free. Students interested in joining should register online before next Wednesday.

There is also a quieter cultural cost that rarely appears in productivity reports. Sensors buried in the soil now report moisture levels in real time, drones survey entire fields for signs of disease within minutes, and automated systems adjust irrigation without a farmer ever walking the rows. ( ① ) For large operations with the capital to invest, these tools have measurably increased yields while reducing water waste. ( ② ) Smaller family farms, however, often cannot afford the upfront cost of this equipment. ( ③ ) Some worry that the gap between high-tech and traditional operations will only widen as the technology advances further. ( ④ ) Generations of farming knowledge, passed down through direct observation of soil, weather, and crops, risk being replaced by dashboards and automated alerts. ( ⑤ )

Motivation, after all, makes learning easier and far more effective. Choosing a college major is one of the biggest decisions many students face after high school. ( ① ) Some students assume that their major will completely determine their future career, but this is not always true. ( ② ) What matters more than the major itself is the set of skills a student develops, such as critical thinking, writing, and problem solving. ( ③ ) These abilities can be applied to almost any career. ( ④ ) However, choosing a major that genuinely interests a student still matters. ( ⑤ ) Therefore, students should choose a major based on curiosity and personal growth, not only on which job it seems to guarantee.
