   "name": "Structured argument",
   "prompt": "Write a 350-word argumentative essay answering: should secondary schools ban smartphones during the school day? Take one clear side, give three distinct supporting reasons, and address one counter-argument. Do not use the phrases 'in conclusion' or 'in today's world'.",
   "output": "Secondary schools should ban smartphones during the school day. While phones can be useful tools outside school, their presence in classrooms, hallways, and cafeterias creates more problems than benefits. A school day should be designed for learning, social development, and student safety, and smartphones often interfere with all three.\n\nFirst, smartphones seriously damage students’ concentration. Even when a phone is on silent, the temptation to check messages, social media, games, or videos remains powerful. Many students are still developing self-control, and expecting them to ignore a device built to capture attention is unrealistic. A clear ban removes that constant distraction and allows teachers to teach without competing against screens.\n\nSecond, banning phones can improve students’ mental health and social relationships. Social media can increase anxiety, comparison, and pressure to respond instantly. During breaks, students need time to talk face-to-face, relax, and build friendships without being pulled into online drama. If phones are unavailable, lunch and passing periods become opportunities for real interaction rather than silent scrolling.\n\nThird, a ban can reduce cheating, bullying, and inappropriate recording. Smartphones make it easy to share test answers, photograph private moments, or record teachers and classmates without permission. These actions can harm trust and create serious discipline problems. Schools already have enough challenges without giving students constant access to a device that can spread harm instantly.\n\nSome people argue that students need phones for emergencies or to contact parents. This concern is understandable, but it does not justify unrestricted phone use throughout the day. Schools can keep office phones available, allow students to contact parents through staff, and create clear emergency procedures. If a student has a medical or family reason to carry a phone, the school can make an individual exception. A general ban does not mean ignoring legitimate needs; it means setting sensible boundaries.\n\nSecondary school students deserve an environment that helps them focus, feel safe, and develop healthy habits. Smartphones are valuable tools, but they are not necessary during lessons, lunch, or passing periods. By banning them during the school day, schools would reduce distraction, support student well-being, and protect the learning community. That trade-off is not only reasonable; it is necessary.",

   "output": "Nuclear power is the most reliable large-scale source of clean electricity we have. It produces huge amounts of energy from tiny amounts of fuel, runs day and night in any weather, uses little land, and has among the lowest lifecycle carbon emissions of any energy source. Unlike fossil fuels, it does not fill the air with particulates, sulfur, nitrogen oxides, or CO₂; unlike variable renewables, it does not require continent-scale storage or backup to keep hospitals, factories, data centers, and homes powered continuously. Modern reactor designs and decades of operating experience have made nuclear one of the safest forms of energy per unit produced, while its fuel is abundant, stockpiled easily, and not subject to the same geopolitical chokepoints as oil and gas. If the goal is deep decarbonization without sacrificing industrial prosperity, nuclear power is not optional—it is the backbone of a serious clean energy system.\n\nBest objection: Nuclear power’s economics are its Achilles’ heel, because many projects in liberalized markets are slow, over-budget, politically fragile, and hard to finance compared with rapidly deployable renewables.",

   "output": "Sleep deprivation weakens memory at several stages. When people stay awake too long, attention becomes unstable, so new information is encoded incompletely and with more errors. Lack of deep slow-wave sleep also disrupts consolidation, the process by which recently learned facts and experiences are strengthened and integrated with older knowledge. As a result, recall the next day can be slower, less accurate, and more vulnerable to interference from similar material. Sleep loss can especially harm working memory, making it harder to hold instructions, solve problems, or update details in mind. Emotional memories may also become distorted, because fatigue increases stress reactivity and reduces the brain’s ability to regulate feelings while remembering. Over time, repeated short sleep can impair learning efficiency and raise the chance of forgetting appointments, conversations, and skills. Restorative sleep, by contrast, supports sharper encoding, stronger consolidation, and more reliable retrieval; no specific study cited is referenced here.",
