Research Question Refiner

I'm working on a research paper for {{course_name}} and need help refining my research question.\n\nBroad topic area: {{broad_topic}}\nMy initial question: {{initial_question}}\nAssignment requirements: {{assignment_requirements}}\nWord/page limit: {{length_limit}}\n\nHelp me by:\n1. Evaluating my initial question (too broad? too narrow? testable?)\n2. Suggesting 3 refined versions that are specific and arguable\n3. For each refined version, identify:\n   - The type of evidence I'd need\n   - Potential sources to look for\n   - The likely counterargument\n4. Recommend which question is most feasible given my page limit\n\nExplain your reasoning so I learn to evaluate research questions myself.
