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've been doing Crossfit, and I think you're about the weight of a tire.  So, I think I could catch you when you fall. 
 Response 1: Oh, this is Hall E. The bottom rung of the E was cut off by that guys giant hat. 
 Response 2: It's true.  I'm very small, and I'm not very dense.
