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'm just going to go get my car's oil changed.  I think that'll make me feel somewhat better.  Hopefully, I won't have any sort of existential crisis within that limited window of time. 
 Response: I admire your optimism.  As a retail buyer, I think you should treat yourself to a little shopping therapy after that oil change.  It calms the angered soul.

A:
yes
