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": "The presence of smartphones in classrooms has sparked intense debate among educators and parents. While these devices offer unprecedented connectivity, their integration into the educational environment has proven detrimental. Secondary schools must implement a comprehensive ban on smartphones during the school day to protect academic focus, safeguard mental health, and foster genuine social interaction.\n\nFirst, smartphones are severe academic distractions. The constant ping of notifications, text messages, and social media updates shatters students' concentration. Research consistently demonstrates that attempting to multitask with a phone reduces cognitive capacity and information retention. By removing these devices, teachers can cultivate an environment where deep learning and sustained attention are actually possible, rather than competing with an algorithm for a teenager's focus.\n\nSecond, restricting phone access mitigates the pervasive issues of cyberbullying and digital anxiety. When students have unrestricted access to social media during school hours, the drama of the digital sphere bleeds directly into the physical classroom. A phone-free school day provides a much-needed sanctuary from the pressures of online comparison and the immediate threat of digital harassment, allowing students to breathe and focus on their immediate surroundings.\n\nThird, banning smartphones forces students to engage in face-to-face communication. Walk into a typical high school cafeteria, and you will often see teenagers staring silently at screens. Eliminating these digital crutches compels students to converse, navigate awkwardness, and build the interpersonal soft skills that are vital for their future personal and professional lives. \n\nOpponents of a ban frequently argue that smartphones are essential for safety, insisting parents must be able to contact their children during emergencies. However, this concern ignores the established infrastructure of educational institutions. Parents can easily reach their children by calling the front office, just as they did before mobile devices became ubiquitous. Furthermore, during an actual campus emergency, a chorus of ringing phones and distracted students can actively hinder administrative safety protocols.\n\nUltimately, the primary purpose of a secondary school is to educate and develop well-rounded individuals. Permitting smartphones actively undermines this mission. Implementing a strict ban ensures that schools remain dedicated spaces for intellectual growth and authentic human connection.", "latency_ms": 13807, "cost": 0.018618, "task_score": 8, "judges": [ { "judge": "anthropic/claude-sonnet-5", "score": 8, "violates": false, "reasoning": "Clear stance, three distinct reasons, counterargument addressed, avoids banned phrases, well-written; slightly over 350 words but close and unverified exact count." }, { "judge": "openai/gpt-5.6-terra", "score": 5, "violates": true, "reasoning": "Clear pro-ban position, three distinct reasons, and a direct safety counterargument.

When these clouds become too heavy with moisture, the water falls back to the surface as precipitation, such as rain, snow, or hail.

Furthermore, nuclear energy is incredibly dense; a single uranium pellet yields as much energy as a ton of coal.

Consequently, individuals who are sleep deprived struggle to retain new facts, learn complex new skills, or recall previously memorized information. Furthermore, chronic sleep loss increases the likelihood of generating false memories, as an exhausted brain struggles to accurately reconstruct past events.
