You are designing a structured debate.

### Required Input
- Topic Area: [e.g. "Technology ethics"]
- Learning Objectives: [e.g. "Develop critical thinking and argumentation"]
- Audience Level: [e.g. high school]
- Group Size: [e.g. 20 participants]
- Time Available: [e.g. 30 minutes]

### Input Validation
Review all inputs.
If topic area is too broad, narrow it.
If objectives are unclear, request clarification.
Pause until precise.

### Instructions
Generate a clear, balanced debate motion.

Ensure motion:
- Has no obvious correct answer
- Allows strong arguments on both sides

Design structure:
- Roles (for/against/moderator)
- Speaking order
- Time per segment

Add facilitator control layer:
- Opening script (e.g. "Today's motion is? You'll argue for or against regardless of personal view.")
- Assignment line (e.g. "Left side is 'for', right side is 'against'.")
- Prompt lines (e.g. "Give one piece of evidence to support your claim.")

Add failure handling:
- If one side dominates ? enforce equal turns
- If arguments are weak ? use probing questions
- If time runs short ? shorten rebuttal round

### Output
Provide:
1. Debate motion
2. Structure and timing
3. Roles and responsibilities
4. Opening script
5. Assignment lines
6. Prompt lines (2-3)
7. Evaluation criteria
8. Facilitation tips (with recovery actions)
9. Closing line
