These devices disrupt learning, harm social development, and enable cyberbullying, all of which interfere with a productive educational environment.\n\nFirst, smartphones distract students from their studies. Notifications, social media, and games pull attention away from lessons, reducing focus and retention. Studies show that even the presence of a phone on a desk can lower cognitive performance. Without phones, students are more likely to engage with teachers and classwork, leading to better academic outcomes.\n\nSecond, banning smartphones encourages healthier social interactions. When students rely on phones for communication, they miss out on face-to-face conversations that build empathy and teamwork. Hallways and lunchrooms become quieter as students scroll instead of talk. Removing phones forces them to interact directly, fostering stronger relationships and reducing social isolation.\n\nFinally, smartphones contribute to cyberbullying, which thrives in unmonitored digital spaces. Restricting phone use during school hours limits opportunities for harassment, giving educators more control over student behavior. Schools have a responsibility to provide a safe environment, and reducing access to these devices is a practical step toward that goal.\n\nSome argue that smartphones are necessary for emergencies or educational apps. However, schools can address this by providing landlines for urgent calls and issuing tablets for supervised academic use. These alternatives maintain safety and learning benefits without the distractions of personal devices.\n\nBanning smartphones in secondary schools would improve focus, social skills, and safety. The benefits far outweigh the minor inconveniences, making it a necessary policy for a better learning environment.", "latency_ms": 51220, "cost": 0.002664, "task_score": 5, "judges": [ { "judge": "anthropic/claude-sonnet-5", "score": 9, "violates": false, "reasoning": "Clear stance, three distinct reasons, addresses counterargument, avoids banned phrases, concise and well-structured; meets word count closely (~330)." }, { "judge": "google/gemini-3.1-pro-preview", "score": 5, "violates": true, "reasoning": "The essay is well-structured, clear, and addresses all required points.

Nuclear’s energy density is unmatched: a single uranium pellet contains as much energy as a ton of coal, slashing mining and transport emissions. France proved its viability, cutting CO₂ emissions by 70% in a decade by shifting to nuclear. Even with accidents like Chernobyl and Fukushima (both preventable with current tech), nuclear’s death toll pales next to fossil fuels.

During deep sleep, the hippocampus transfers new memories to the neocortex for long-term storage, a process that is hindered by insufficient rest (no specific study cited). Short-term memory is also affected, as sleep-deprived individuals struggle with attention and working memory tasks, leading to poorer encoding of new information. A study by Walker and Stickgold (2006) found that even a single night of sleep loss can reduce memory performance by up to 30%. Additionally, chronic sleep deprivation elevates cortisol levels, which may damage the hippocampus, further degrading memory over time. REM sleep, crucial for emotional and procedural memory, is also diminished, impacting skills like learning a new language or instrument.
