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...'. 
One example is below.
Q: Prompt: I'm glad you came into my office today, young man. Look around you. Everything that's in here, I purchased. 
 Response: Wow! You own everything in this office?
A: yes
Rationale: This is correct answer because response is in support with the prompt and extends the context from prompt.
Q: Prompt: Wow, there's a lot of chemistry going on between you and the guy in the corner there. You guys got a little banter going on. A little Ross and Rachel. 
 Response: Yeah, you sound a little like Nichols and May. They're one of my favorite duos.
A:
yes
