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...'. 

Prompt: I'm so hungry I'm starting to think maybe I should eat some of these Icelandic weeds. 
 Response: Wait, wait. We gotta wait. We don't know if that's breakfast or not. And I don't want to pay for it if it's covered. Like lunch, I know, I gotta pay for. But breakfast, if it's part of the whole Trivago thing we did, I don't want to have to pay for it if it's free.
yes

Prompt: I lost your peaches.
