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, your headshot is pretty professional, but based on your behavior I'm going to say you're actually not. 
 Response 1: Yeah, they didn't exist back then, I don't think. 
 Response 2: It's an iPhone 7 Plus. I used the depth feature.
