A biosensor works by pairing a biological component, such as an enzyme or antibody, with an electronic device that converts a biological reaction into a signal a computer can ①read. When the target molecule, whether glucose in blood or a trace of a pathogen, binds to the biological component, it triggers a ②massive measurable change that the device translates into a readable number. This design has already transformed diabetes management, letting patients monitor blood sugar ③continuously through a small sensor worn under the skin rather than pricking a finger several times a day. Engineers are now racing to extend the same principle to detect subtler targets, from cancer cells circulating in the bloodstream to trace ④contaminants in drinking water. The central challenge is not detecting the target but doing so reliably outside a controlled laboratory, since a sensor that performs well on a clean lab bench can behave ⑤erratically once exposed to a real body or a real river.

Psychologist John Suler proposed a concept called the online disinhibition effect, describing how people behave differently on the internet than they do face to face. Because usernames often hide real identities and screens create physical distance from others, individuals feel freer to express themselves without immediate social consequences. This freedom can be ①beneficial, allowing shy people to share honest feelings they would normally hesitate to reveal in person. However, the same anonymity frequently produces a ②darker outcome, encouraging users to post cruel comments they would never say to someone's face. ③Malicious remarks left under celebrities' photos or news articles illustrate how quickly this behavior can spread once a few users set the tone. Such comments often cause ④severe emotional harm to the people who receive them. Therefore, users must recognize that a screen does not erase moral responsibility, and platforms should ⑤weaken accountability rather than letting anonymity excuse harmful conduct.

For most of last year, Junho refreshed his social media feed constantly, terrified of missing a party, a trending meme, or gossip among his friends. This restless anxiety, often called FOMO, or the fear of missing out, left him exhausted and strangely unsatisfied even after hours of scrolling. One weekend, his phone battery died during a hiking trip, and, to his surprise, he actually enjoyed the quiet afternoon without notifications interrupting his thoughts. Curious about this unexpected calm, Junho began deleting social apps for a few hours each day, gradually extending the breaks as weeks passed. Instead of dreading what he might be missing, he started noticing small pleasures, such as finishing a book or having an uninterrupted conversation with his family. This shift in attitude reflects ___________.

Many teenagers check their social media accounts dozens of times a day, worried that they might miss something important happening among their friends. This anxiety, known as FOMO, or the fear of missing out, arises when people believe that others are enjoying experiences from which they themselves are excluded. For example, a student scrolling through photos of a party she was not invited to may suddenly feel a wave of loneliness and regret, even though the event has already ended. Constantly refreshing feeds to avoid missing such updates, however, makes it difficult to concentrate on schoolwork or conversations happening in the present moment. Moreover, this endless comparison with curated highlights of other people's lives tends to deepen feelings of anxiety rather than relieve them. Therefore, students should learn to ___________.

Sorting your trash correctly is _______________. When you separate paper, plastic, glass, and cans, recycling centers can process each material more efficiently. For example, plastic bottles should be rinsed and have their caps removed before being thrown away. Paper soaked with food or oil, however, cannot be recycled and must go into general waste. Sorting garbage is similar to organizing a closet, where each type of clothing has its own shelf. If items are mixed together carelessly, finding what you need later becomes difficult. Likewise, mixing recyclables with ordinary trash makes the whole recycling process complicated. Many students believe that sorting trash takes too much time, but it actually requires only a few extra seconds. Therefore, learning these basic rules now helps you build a habit that benefits your entire community.

Every morning, our broadcasting club airs a short news program for the entire school. Last Tuesday, I was chosen to read the weather report for the very first time. (A) My partner Minho, who was sitting beside me, quickly slid the script closer to me. I took a deep breath and calmly continued reading from where I had stopped. (B) My hands were shaking as the red light on the camera turned on. Halfway through my sentence, I suddenly forgot the next line completely. For a few seconds, only silence filled the studio, and I could hear my own heartbeat. (C) Somehow, my voice sounded steadier than I expected, and I finished the report smoothly. After the broadcast ended, several classmates told me they had not even noticed the pause. That morning taught me that small mistakes rarely matter as much as we fear.

Scientists have studied exactly how a habit becomes part of daily life over time. (A) In the early stage, the brain still treats the new activity as unusual, so a person must rely heavily on willpower to continue. (B) By the final stage, the behavior no longer requires effort, since it has become a natural and comfortable part of the daily routine. (C) As the weeks pass, the behavior gradually becomes easier because the brain begins to expect it at a certain time each day.

Psychologists have long debated why some people find it easier than others to wait for future rewards. (A) For example, children who distracted themselves by singing or looking away were far more successful at waiting. (B) One explanation involves specific strategies, such as focusing attention away from the tempting object. (C) In the original marshmallow studies, researchers observed that success depended heavily on how children managed their attention.

The twenty-hour rule has become popular among adults who want to pick up new hobbies despite busy schedules. (A) She practiced basic shading and proportion for about ninety minutes each day, carefully tracking her total hours. (B) A woman who always wanted to sketch, for example, decided to test the rule during a two-week vacation. (C) By the time she reached twenty hours, she could produce simple portraits that she was proud to share with friends.

Many students confuse the student council with school clubs. In fact, the two groups serve very different purposes. (A) Therefore, joining the council usually requires an election, whereas joining a club simply requires genuine interest. Some students eventually do both, using the council to build leadership skills and a club to develop a personal passion. (B) The student council is an official body that represents the whole school. It manages shared issues such as rules, events, and communication with teachers. For example, council members often organize the school festival and collect opinions from each class before making decisions. (C) A club, in contrast, is a small group formed around one shared interest, such as music or art. While the council must consider the needs of every student, a club can focus narrowly on what its own members enjoy.
