**Result**: ✅ Supported (90% confidence)
- Multiple sources confirm this projection

### Poor Example: Opinion Statement
**Selected Text**: "Our AI solution is the most innovative in the market"

**Result**: ⚠️ Insufficient Information (30% confidence)
- This is a subjective claim that cannot be objectively verified
- No measurable criteria for "most innovative"
- Consider rephrasing with specific, verifiable benefits
