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: Everybody knows the Wizard of Oz. That's the first thing you learn in history class.
Response 1: Amelia? He seems pretty nice. OK, hop on back, hitchhiker. The chair reclines and leans forward.
Response 2: Yeah, we know that. That's why we had to learn to spell from an encyclopedia.
Output:
Response 2
