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: Oh, I see over there on the counter by the register that you've got a list of today's deal and discounts, but it doesn't look like a chalkboard. 
 Response 1: Yeah, it's made of different material.  You don't use chalk on it.  It's this shiny material that's pretty amazing.  You can write on it like a chalkboard, but you're using a marker, and then you can erase it with a napkin. 
 Response 2: The second thing. I'm so sorry.
