Definition: "Yes, and" is a rule-of-thumb in improvisational comedy that suggests that a participant in a dialogue should accept what another participant has stated ("Yes") and then expand on that line of thought or context ("and..."). Given a prompt and two responses, identify which response is the type of "yes, and". Indicate your answer by 'Response 1' if the first response is correct, otherwise 'Response 2'.  Note that a "Yes, and" does not require someone explicitly saying 'yes, and...' as part of a dialogue exchange.
Input: Prompt: I noticed them flying, but thought what was really distinctive about these kids is their enthusiasm. 
 Response 1: The only way they could make things better would be if they killed those dirty fake mable syrup drinkers but we know they will never be willing to do that. 
 Response 2: I was definitely struck by their flying ability. I haven't seen that before.
