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: Listen, normally I just like small groups of people, like three. But I've learned in my heart that sometimes there's bigger groups of people around and I've got to get with the times. So, Alexandro, will you marry me? 
 Response 1: Lisa, as much as I don't like to talk about myself, you asked me a question. And the answer to that question is yes. Yes, I will marry you, Lisa. 
 Response 2: I got an idea. He's probably thinking of the next big business move he's going to make for this company.
