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 took a can of soup and I tried to turn it into a swimming pool for dogs. 
 Response 1: Wait a minute, Doris, wouldn't you be interested to know if there's a world out there in which you succeeded with your swimming pool, and another where you didn't? To see what happened? 
 Response 2: Well, certainly. One of them of course is blood nut.
