Pacing Manage time effectively

4.3 Handling Questions

 
 
Question Type Strategy
Clarification Clarify and answer directly
Challenge Acknowledge, respond with evidence
Expansion Welcome and explore the idea
Unknown Be honest, offer to follow up
Technical Answer with confidence
Broad Keep answers focused and relevant
