TASK DEFINITION: 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...'.

PROBLEM: Prompt: The timing of this seems a little weird, that you want me to do this now. 
 Response: Cards on the table. I worry, because of my secret love for Meredith, that she's mixed up with a bad guy who is also Janice's husband perhaps. Or at the very least her baby daddy. So I want to expose this Jonathan.

SOLUTION:
yes
