   "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 to protect students’ learning, well-being, and development. Constant access to these devices undermines the core purpose of education and creates unnecessary risks that schools are equipped to manage without them.\n\nFirst, smartphones shatter concentration. Notifications, messages, and apps pull attention away from lessons every few minutes. Studies consistently show that even the mere presence of a phone reduces cognitive capacity and working memory. When devices are locked away, students engage more deeply with teachers and material, leading to stronger comprehension and higher achievement.\n\nSecond, bloats of screen time fuel anxiety and cyberbullying. Social media algorithms reward comparison and drama; during school hours these pressures intensify among peers who are physically together yet digitally divided. Removing phones cuts off real-time harassment and the compulsive checking that elevates stress hormones. Students regain mental space to process emotions without the distorting filter of likes and comments.\n\nThird, the ban restores genuine human connection. Lunchrooms and hallways become places for conversation, games, and collaboration rather than silent scrolling. Face-to-face interaction builds empathy, conflict-resolution skills, and a sense of belonging that no app can replicate. Physical activity also rises when phones no longer tether students to benches.\n\nCritics argue that phones are essential for parental contact in emergencies. Schools already maintain robust communication systems—office phones, intercoms, and designated staff—who can reach families instantly. In true crises, administrators can release devices quickly. The rare need for immediate contact does not justify all-day access that harms the majority.\n\nBy enforcing a clear ban, secondary schools reclaim the classroom as a focused, safer, and more social environment. Students leave better prepared academically and socially, carrying habits of presence that serve them long after the final bell.",

   "output": "The water cycle describes how water moves on, above, and below the Earth's surface.

This vapor cools and condenses into clouds. When clouds become heavy, precipitation occurs as rain, snow, sleet, or hail. Water then flows as runoff into bodies of water or infiltrates the ground to become groundwater. Eventually, it returns to oceans, completing the cycle. This continuous process is essential for life on Earth, distributing water and regulating climate.\n100",

   "output": "Sleep deprivation significantly impairs memory in multiple ways, affecting both the formation and recall of information. When individuals do not get enough sleep, the brain's ability to consolidate memories is hindered because this process largely takes place during various sleep stages, including deep sleep and rapid eye movement sleep. As a result, facts and experiences from the day before are less likely to be transferred effectively into long-term storage. Additionally, sleep loss reduces the efficiency of memory encoding by diminishing attention and focus, making it harder to absorb new information in the first place. Retrieval processes also suffer, with sleep-deprived people often struggling to access stored memories quickly or accurately. Working memory, which is essential for temporary holding and manipulating information, is particularly vulnerable, leading to difficulties in complex cognitive tasks. Over time, chronic sleep deprivation can contribute to more severe memory deficits and may elevate risks for cognitive disorders. no specific study cited",
