Devices that translate brain activity directly into digital commands have moved from laboratory experiments to real medical use, ①allowing paralyzed patients to control a robotic arm or type a message using thought alone. As the technology improves, some developers envision a future in which brain-computer interfaces extend beyond restoring lost function ②toward enhancing healthy minds, offering faster memory or expanded attention to anyone ③willing to undergo the procedure. This prospect raises a philosophical question that medicine alone cannot answer: if a device can alter memory, mood, or decision-making, at what point does the assistance stop ④being a tool and start reshaping the very identity of the person using it. Neuroethicists argue that mental privacy, the ability to keep one's own thoughts free from external access or manipulation, may need ⑤recognizing as a fundamental right before this technology becomes widespread.

Wearable devices that track sleep have become enormously popular, promising a detailed breakdown of light, deep, and REM sleep each night. These gadgets typically rely on movement sensors and heart rate monitors to estimate sleep stages, since directly measuring brain activity would require equipment found only in a sleep laboratory. This indirect approach, however, introduces significant uncertainty. Independent studies comparing wearable data with polysomnography, the gold-standard method used in clinical sleep labs, have found that _______________. Some trackers overestimate deep sleep, while others underestimate the amount of time spent in REM sleep, and the margin of error can vary widely between brands. Despite these limitations, many users have come to treat the nightly score generated by their device as an objective medical verdict, sometimes experiencing anxiety when the number falls below what they expect, a phenomenon researchers have begun calling orthosomnia.

A small riverside village had endured severe flooding almost every summer, watching helplessly as rising water damaged homes and destroyed crops year after year. Frustrated residents eventually decided to _______________. Engineers widened the drainage canals surrounding the village, allowing excess rainwater to flow away more efficiently instead of pooling in low-lying streets. Meanwhile, several families whose houses stood in the most vulnerable areas relocated to higher ground, even though leaving their long-time homes was emotionally difficult. The village also installed an early warning system that sent alerts to residents' phones whenever river levels rose dangerously fast. When a powerful storm struck three years later, the new measures proved effective, and the village suffered only minor damage instead of the devastating losses it had previously faced. Their resilience became a model for neighboring communities.

More and more teenagers today dream of starting their own business someday. Some students design and sell handmade jewelry online, while others create simple mobile apps as a hobby. Starting a small business also teaches skills that traditional classes rarely offer, such as managing money, marketing a product, and handling customer complaints. However, young entrepreneurs face real challenges too, and mistakes can feel discouraging at first. Still, most teen entrepreneurs say that ___________. For this reason, schools are beginning to offer entrepreneurship clubs, giving students a safe space to test their business ideas.

Jimin joined the school band club in March, but she had never performed before an audience. The club's first concert was only two weeks away, and everyone felt nervous. During practice, her hands shook whenever the song reached the chorus, and she kept missing the same chord. Instead of laughing at her mistakes, the other members waited patiently and played the section again with her. The drummer, Suho, suggested that she focus on just one part at a time. Slowly, her fingers grew more confident, and the chord that once felt impossible began to feel natural. The club practiced until the melody sounded smooth the night before the concert. When Jimin walked onto the stage, she thought of her friends' patience instead of her fear. The audience clapped warmly, and she realized _______________________.

Online advertising has become increasingly personalized as algorithms analyze user behavior in real time. (A) Critics, however, warn that this precision can be used to exploit psychological weaknesses rather than genuinely help consumers. (B) Supporters claim that this precision benefits users by reducing the number of irrelevant advertisements they encounter. (C) Given these opposing views, many experts call for greater transparency about how such algorithms actually operate.

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.

Hospitals are increasingly adopting artificial intelligence tools that can scan medical images and flag potential tumors faster than experienced radiologists. (A) The doctor may argue that they simply trusted a tool the hospital required them to use, while the hospital may blame the software company instead. (B) Yet the growing reliance on these tools raises an uncomfortable legal question: when an AI system misses a diagnosis, who is responsible? (C) Until legal systems clarify this chain of responsibility, patients harmed by an algorithmic error may find themselves with no clear party to hold accountable.

Blockchain technology was originally promoted as a way to remove the need for trusted middlemen, allowing strangers to exchange value directly through a shared, tamper-resistant ledger. (A) In practice, however, a small number of large players have come to dominate many blockchain networks, controlling enough power to influence outcomes that were supposed to be decided collectively. (B) In theory, this design distributes power away from any single institution and toward the network as a whole. (C) Critics note a further irony: when something goes wrong, there is often no institution left to appeal to, since the system was designed to eliminate central authority.

주어진 문장: These various booths give every member a chance to show what they have practiced throughout the year. Every October, Greenfield High School holds a festival that gives every club a chance to shine. ① This year's festival will take place on October 15th, running from nine in the morning until four in the afternoon. ② Clubs that want to run a booth must apply to the student council by October 1st, since space in the gym is limited. ③ The science club will present simple experiments that are both safe and exciting to watch. The art club, meanwhile, will display paintings that members have created throughout the semester. ④ The cooking club plans to sell snacks prepared by its own members, and all the profits will be donated to a local shelter. ⑤ Because many visitors are expected, teachers will supervise each booth carefully to keep students safe. Anyone curious about club life is warmly encouraged to visit and enjoy the festival.
