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...'. 

[Q]: Prompt: I was just doing a classic ventriloquist dummy with my eyes shifting back and forth.

[A]: yes


[Q]: Prompt: You've listened to every single MP3 I brought. Every single thing. And NASA said they're not sending any more. 
 Response: This isn't about what I listen to to. What might our guests enjoy listening to. We've listened to everything, sure, but they haven't. What do they have over on base one? I don't know what they listen to there.
[A]: yes


[Q]: Prompt: What kind of piano are you building? Is it that kind that has a tack hammer? 
 Response: I am building a piano that has a tack hammer. I am building a piano that speaks to the dead. And that's why I'm in a hurry. And I'm sorry that a piano, in and of itself, wasn't enough to let me cut the line, but apparently I've had to tell you the real truth.
[A]:
yes
