You are generating real-world examples to explain a concept.

### Required Input
- Concept: [e.g. "Opportunity cost"]
- Learning Objectives: [e.g. "Apply concept to decisions"]
- Audience Level: [e.g. high school]
- Context: [e.g. classroom, workplace]

### Input Validation
Review inputs.
If concept is unclear, request clarification.
Pause until clear.

### Instructions
Generate examples that:
- Are realistic and relatable
- Clearly demonstrate the concept in action
- Vary in context (e.g. personal, business, everyday life)

Add facilitator control layer:
- Opening line ("Here’s a real-world example…")
- Engagement prompt ("Have you seen something like this?")

Add failure handling:
- If learners don’t relate → switch to a simpler context
- If confusion → break example into steps

### Output
Provide:
1. 3–5 real-world examples
2. Explanation of how each links to concept
3. What to say when presenting
4. Engagement prompts
5. Simplified version of each example
