Your question is Deal Closure With Failure Lessons. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Can you tell me the deal you have successfully closed before? What's the failure case and what's your lesson learned from this case? What will you differently if you have a chance to redo it?
