Given the prompt and a response, classify the them to "yes" if response is "yes, and" type. Otherwise classify it as "no". "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..."). 1 In short, a "Yes, and" is a dialogue exchange in which a speaker responds by adding new information on top of the information/setting that was constructed by another speaker. Note that a "Yes, and" does not require someone explicitly saying 'yes, and...' as part of a dialogue exchange, although it could be the case if it agrees with the description above. There are many ways in which a response could implicitly/explicitly agree to the prompt without specifically saying 'yes, and...'. 

Example Input: Prompt: Thank god, the elevator is working. That was scary. I think maybe it's just that the elevator is haunted. 
 Response: Oh that might be it? That's terrifying. We're still on it.
Example Output: yes

Example Input: Prompt: Printing photos is sort of obsolete now. 
 Response: Yes, that is why this is the last day we'll be open. We won't be processing photos anymore. We're closing up shop.
Example Output: yes

Example Input: Prompt: Yeah, so your friends tell you to go to a Phish concert. They give you weird instructions, tell you to meet a regular. Just to get you out of their hair. 
 Response: It used to be called a Spring-stomp. You'd send someone to a Springsteen concert, to stomp out the friendship.
Example Output:
yes
