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: Well, since I have y'all in my car, I've been testing out a pilot of my podcast. WhopperMac, you know, testing to see which Whopper is better than a Bic Mac and which Big Mac is better than the Whopper. From different McDonald's and Burger Kings from around the country. 
 Response 1: So you're a scientist? Like a burger scientist? 
 Response 2: That's right. I kept my freak flag furled.
