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: Lynn, darling. I feel as if we have to do some sort of warm up exercises before we go out on stage tonight. 
 Response 1: In my background, we did a lot of improv games. Perhaps we can do a little bit of pass the clap. 
 Response 2: I am. I'm thinking that we should all create a musical group, like Abba.
