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: This is actually not a cave, Stuart. Most of you blacked out when the wave hit. We're in the belly of a whale. 
 Response 1: We're in a whale, in a whale belly. Look around, as you can see, all of this is belly. You can't see any other organs, because you're inside the actual belly. 
 Response 2: Oh, we probably shouldn't have all been here at the same time in the break room.
