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: It means streets, but it's just their name. 
 Response 1: Oh, the mean streets? Rock n rollers love the mean streets. 
 Response 2: I'm not afraid of this whale. There's not a vessel that floats in this man's ocean that I haven't been able to tame to this day.

Response 1
