   "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 students from using smartphones throughout the school day, while allowing devices to be stored securely for emergencies and collected afterward. Although phones can support communication and quick research, their constant presence undermines the central purposes of school: sustained attention, healthy social development, and fair access to learning. A clear ban would create calmer, safer, and more productive classrooms.\n\nFirst, smartphones damage concentration. Lessons require students to listen, question, remember, and connect ideas over time. Notifications, games, videos, and group chats compete for that attention, even when a phone remains silent in a pocket. Teachers then lose valuable minutes policing screens or repeating instructions. Removing phones establishes one simple expectation: during school, students focus on learning. This benefits everyone, especially pupils who already struggle with distraction.\n\nSecond, a ban would improve relationships and wellbeing. Corridors, lunch periods, and free moments should give young people opportunities to speak face to face, resolve minor conflicts, and develop confidence. Instead, phones can encourage isolation, social comparison, filming without consent, and rapid online bullying. Schools cannot eliminate every digital harm, but they can protect several hours each day from the pressure of constant online life, creating a more restorative environment.\n\nThird, banning smartphones promotes fairness. Not every family can afford the latest device, a large data plan, or paid learning applications. When teachers casually rely on personal phones, wealth differences become visible and may affect participation. School owned computers and tablets can provide filtered, supervised, and consistent access when technology genuinely improves a task. Learning should depend on shared resources, not on what each student carries.\n\nCritics argue that phones are useful for emergencies and classroom research. Those benefits are real, but they do not require unrestricted student access. Families can contact the school office, and administrators can reach a child; students with medical needs can receive exemptions. For planned digital work, schools can provide approved devices under teacher supervision. A firm ban should therefore include sensible exceptions, secure storage, and consistent enforcement. With those safeguards, schools would not reject technology; they would place education, safety, and human connection above checking.",

Water then collects in bodies of water, soaks into the ground, or flows downhill as runoff. Groundwater may feed springs and streams, while ice stores water temporarily. Eventually, most water returns to oceans, and the process repeats endlessly.\n\n100",

It doesn’t mean every price rises—just that many prices increase overall.\n\n**For an economics undergraduate:**  \nInflation is a sustained increase in the economy’s general price level, reducing money’s purchasing power. It is commonly measured using indices such as the CPI or GDP deflator. Inflation may result from excess aggregate demand, rising production costs, supply shocks, or expansionary monetary policy. Unlike a change in one product’s relative price, inflation affects prices broadly. Expectations can also make inflation persistent through wage- and price-setting behavior.",

   "output": "Nuclear power is the strongest scalable source of clean, reliable electricity. It produces near-zero lifecycle carbon emissions, uses far less land and material than most alternatives, and operates around the clock regardless of weather. Its exceptionally dense fuel supply can support industrial economies while reducing dependence on fossil fuels, massive storage systems, and sprawling transmission networks. Nuclear plants also have among the lowest death rates per unit of energy produced, even accounting for major accidents. Existing reactors prevent huge quantities of air pollution and carbon emissions; extending their lives is often one of the fastest, cheapest ways to preserve clean generation. Standardized designs, experienced builders, and disciplined regulation can make new construction predictable, while modern reactors can improve passive safety and fuel efficiency. A power system that combines nuclear energy with renewables can decarbonize electricity while maintaining the reliability needed for electrified transport, heating, and industry.\n\n**Best objection:** New nuclear plants in many countries have proved too slow and expensive to build, so scarce climate funds may cut emissions faster when spent on renewables, grids, storage, and efficiency.",

   "output": "Sleep deprivation harms memory at several stages. When people do not get enough sleep, attention becomes less stable, so new information is encoded less accurately in the first place. Lack of sleep also disrupts consolidation, the process by which recently learned material is strengthened and integrated with existing knowledge. As a result, facts, skills, and experiences may be recalled less reliably the next day. Working memory is also affected: sleep-deprived people often struggle to hold and manipulate information, follow multistep instructions, or resist distraction. Emotional memories may become especially distorted because fatigue can intensify negative reactions while weakening cognitive control. Chronic sleep restriction can compound these problems, producing persistent forgetfulness and poorer learning performance. Recovery sleep may improve functioning, but it does not always immediately reverse every deficit, particularly after repeated nights of inadequate rest. Overall, sufficient, regular sleep supports attention, memory formation, consolidation, and retrieval; no specific study cited.",
