The discovery of CRISPR gene-editing technology gave scientists a tool precise enough ① to correct a single mistaken letter in the human genome, raising hope for curing inherited diseases that have resisted treatment for generations. Yet the same precision that makes CRISPR so promising also makes it dangerous in the wrong hands. Editing a gene in a sperm, egg, or early embryo does not simply change one patient; it alters the genetic code ② passed down to every future generation, a decision no single person should ③ allow to make alone. Scientific organizations around the world have therefore drawn a careful line, ④ permitting gene editing to treat disease in existing patients while banning any edit that would be inherited by their descendants. Critics worry, however, that this line will become harder to enforce than it ⑤ is to draw.

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.

When individuals face uncertainty about how to behave, they frequently look to the actions of others for guidance. This reliance on collective behavior can be remarkably ①efficient, since it allows individuals to benefit from the accumulated judgment of a crowd without having to gather and evaluate every relevant fact themselves. However, social proof can also lead entire groups astray when the initial signal that triggers imitation is itself ②unreliable or coincidental. A restaurant that happens to attract a long line early in the evening may continue attracting customers throughout the night simply because passersby interpret the queue as evidence of ③inferior quality. Financial markets exhibit an analogous pattern: investors who observe others buying a particular asset often join the buying themselves, reasoning that so many participants cannot all be mistaken, a dynamic that can ④inflate prices well beyond any reasonable estimate of underlying value. Because conformity can substitute for independent judgment so ⑤seamlessly, individuals rarely notice when their own decisions have become mere imitations rather than genuinely deliberated.

Factories that once employed hundreds of workers on an assembly line now run with a ① fraction of that staff, as robotic arms handle tasks that used to require human hands. Economists have long debated whether this shift destroys jobs or simply transforms them. Historical evidence offers some ② comfort: previous waves of automation eventually created new categories of work that no one had predicted. However, critics point out that earlier transitions unfolded over generations, giving workers ③ ample time to retrain, whereas today's robots are being deployed at a pace that leaves little room for adjustment. A factory worker displaced this year cannot simply wait for a new industry to emerge decades from now. For this reason, many economists argue that the real ④ challenge is not the robots themselves, but the ⑤ sluggish speed at which society is expected to adapt to them.

Last spring, I joined a one-day job experience program at a local hospital. At first, I was ①nervous about talking to real patients. However, after helping an elderly patient find her room, I felt ②proud and relaxed. The busiest moment came when several patients needed attention at once, and the nurses worked together ③calmly. I realized that teamwork matters as much as medical knowledge, and my interest in nursing had grown even ④stronger. This short experience taught me ⑤less about the job than any book could.

As technology develops rapidly, many new jobs are appearing that did not exist a decade ago. Data analysts, for example, help companies make decisions based on huge amounts of information. Renewable energy technicians install and repair solar panels and wind turbines. Healthcare is expanding beyond hospitals, creating roles for specialists who design digital health tools for elderly patients. These emerging jobs share one common feature: ___________. Experts predict that future workers will need to keep learning new skills throughout their careers.

VO2 max, defined as the maximum volume of oxygen a person's body can consume and use during intense exercise, is widely regarded as one of the best single indicators of cardiorespiratory fitness. (A) Elite endurance athletes typically post VO2 max values far higher than those of untrained individuals, reflecting hearts that pump larger volumes of blood and muscles that extract oxygen with remarkable efficiency. (B) While genetics accounts for a substantial portion of an individual's potential VO2 max, consistent aerobic training can still raise the measurement considerably over months of dedicated effort. (C) It is worth noting, however, that a high VO2 max does not guarantee success in competition, since other factors such as pacing strategy and mental resilience also play a decisive role.

As private companies develop the technology to mine asteroids for rare metals and water, a legal question once confined to science fiction has suddenly become urgent: who, if anyone, owns the resources of outer space? (A) Some governments have already passed domestic laws granting their own companies rights to material mined in space, a move other nations view as a unilateral attempt to settle a shared question. (B) Existing international treaties state that no nation may claim sovereignty over celestial bodies, but they say remarkably little about whether a private company may extract and sell what it finds there. (C) Supporters of space mining argue that new resources could ease shortages on Earth, while critics warn that treating space as an open frontier for extraction risks repeating past mistakes.

Introducing cobots into a factory requires careful planning to ensure both safety and productivity. (A) Once installed, however, cobots must be closely monitored, since their sensors can occasionally malfunction in noisy or crowded environments. (B) Engineers must first program the robots to recognize the exact boundaries of each worker's movement space. (C) After this initial setup, cobots can be integrated gradually, starting with simple tasks before taking on more complex ones.

As more schools shift toward digital textbooks and online assignments, a student without reliable internet access at home faces a disadvantage that has little to do with talent or effort. (A) That assumption is increasingly being reconsidered, particularly as more essential services, from job applications to medical appointments, move online by default. (B) Some policymakers initially treated internet access as a convenience, comparable to cable television, rather than as infrastructure essential to modern life. (C) Closing this divide will require more than simply distributing devices; it will demand sustained investment in the physical networks that carry information into every home.
