A biosensor works by pairing a biological component, such as an enzyme or antibody, with an electronic device that ①convert a biological reaction into a signal a computer can read. When the target molecule, whether glucose in blood or a trace of a pathogen, ②binds to the biological component, it triggers a small measurable change that the device translates into a readable number. This design has already transformed diabetes management, ③letting patients monitor blood sugar continuously 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 ④to detect subtler targets, from cancer cells circulating in the bloodstream to trace contaminants 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 erratically once ⑤exposed to a real body or a real river.

Yesterday, I ①visited my school's career counselor because I felt confused about my future. I told her that I enjoyed both science and art, but I could not decide which subject ②to pursue. She listened carefully and then asked me a simple question: what activities ③make me lose track of time? She suggested that I try ④combining my two interests by exploring careers such as scientific illustration or product design. Before I left, she reminded me that career paths rarely follow a straight line, so it was fine ⑤explore multiple directions.

Conventional economic wisdom holds that more options are always preferable to fewer, since a larger set of alternatives ①increases the likelihood that any individual will find one that precisely matches their preferences. When shoppers are presented with an extensive array of choices, they frequently experience heightened anxiety about making the wrong selection and, paradoxically, become ②less likely to make any purchase or decision at all. Furthermore, individuals who do eventually choose from an overwhelming array often report ③higher satisfaction with their selection than those who chose from a modest handful of options, since the sheer number of unexplored alternatives ④fosters lingering doubt about whether a better choice was overlooked. Businesses that recognize this dynamic have begun deliberately ⑤curating smaller, carefully selected assortments, betting that a narrower range of options can sometimes generate more sales and greater customer satisfaction than abundance.

Psychologist Roy Baumeister proposed a concept called ego depletion theory, which suggests that willpower functions like a muscle that gradually ①strengthens after repeated use. According to this theory, every act of self-control, from resisting a snack to concentrating on difficult homework, draws from the same ②limited mental resource. As this resource becomes ③depleted throughout the day, later decisions require more effort and are more likely to fail. For instance, someone who exercises discipline avoiding distractions all morning may ④struggle to resist checking a phone by evening. Likewise, dieters report that self-control weakens sharply at night, after hours of resisting food. Some researchers argue that short breaks, adequate sleep, and blood sugar levels can help ⑤restore this depleted resource.

At first, Minjun thought the campaign sounded ①boring and unnecessary for someone like him. However, his teacher explained that leftover food thrown away every day adds up to a ②huge amount of waste. This comparison ③surprised Minjun because he had never thought about food that way before. Within a few weeks, his tray was almost always ④full, and he felt ⑤proud of the change.

The discovery of CRISPR gene-editing technology gave scientists a tool precise enough to correct a single mistaken letter in the human genome. Yet editing a gene in a sperm, egg, or early embryo does not simply change one patient; it alters the genetic code passed down to every future generation. Scientific organizations around the world have therefore drawn a careful line, permitting gene editing to treat disease in existing patients while banning any edit that would be inherited by their descendants. Critics worry, however, that _______________.

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.

Many students wonder why club activities matter so much for their school life record, a document that summarizes what a student did during each semester. (A) For example, a student who organized a club exhibition might be described as someone who showed strong leadership and creativity. These notes are not simply a list of activities; they explain the process behind each achievement. (B) Whenever students take part in a club, their teacher writes a short note describing what role they played and how they grew. (C) Therefore, admissions officers at universities read the record carefully to understand a student's genuine interests, not just their grades. In contrast, a club membership with no real participation rarely leaves a meaningful impression. This is why teachers encourage students to take an active role rather than joining a club only for its name.

Meanwhile, the underlying technology continues to advance regardless of whether the diplomacy meant to govern it keeps pace. Military researchers have developed weapons systems capable of identifying and engaging targets without a human pressing the final button, a prospect that has alarmed arms control experts for over a decade. ( ① ) Advocates within defense agencies argue that autonomous systems can react faster than any human operator and may even reduce casualties. ( ② ) Human rights organizations counter that removing a person from the final decision strips away moral responsibility at the exact moment it matters most. ( ③ ) Diplomatic negotiations toward an international treaty have repeatedly stalled, partly because military powers disagree on how to define autonomy precisely enough to regulate it. ( ④ ) This disagreement has left the treaty process without a clear path forward. ( ⑤ )

For this reason, many economists argue that the real challenge is not the robots themselves, but the speed at which society is expected to adapt to them. 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. ( ① ) Economists have long debated whether this shift destroys jobs or simply transforms them. ( ② ) Historical evidence offers some comfort: previous waves of automation eventually created new categories of work that no one had predicted. ( ③ ) However, critics point out that earlier transitions unfolded over generations, giving workers time to retrain, whereas today's robots are being deployed at a pace that leaves little room for adjustment. ( ④ ) A factory worker displaced this year cannot simply wait for a new industry to emerge decades from now. ( ⑤ )
