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: Hey, Lacey. Remember the last time we picked up a hitchhiker? Trouble. 
 Response 1: Oh, yeah, one of our friends was murdered. We probably really shouldn't help you out, it's dangerous for us. 
 Response 2: Oh, lead with both. Mix them together. Use one word from each sentence and we'll decipher it.

Response 1
