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: Thank you so much for bringing our drinks. Do you want to have one with us? 
 Response 1: I set up a hypothesis, that the wall was strong enough. Tested it. Turned out to be right. With an unintended conclusion that the helmet was not quite strong enough. 
 Response 2: I'm already drunk, so why not.
