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: Now, just so you know, the ghost train isn't physically solid. So, we're going to be on these tracks and another train might pass right through us. But, that's very unlikely. 
 Response 1: Fine by me. I'm not solid either. 
 Response 2: You're wearing a dead man's hat, woman. Don't start in with me.

Response 1
