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'm sorry the boombox thing is confusing. I couldn't find 18 D batteries, so it's not playing any music. 
 Response 1: Gotta be a lot lighter though. Right friend? 
 Response 2: Yeah we were trying to figure out the best way to see most of Houston and we see a restaurant named Houstons and we thought we'd kill two birds with one stone.
