TASK DEFINITION: Given the sentence, generate "yes, and" response. "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: I am pretty sure I am from Russia but I'm not 100% where any of you are from.

SOLUTION: Catarina, we work so long together. And now you ask me this, where we are from?

PROBLEM: Tom, we're trying to get a nice gift for our parents. Do you recommend a russet or the red ones?

SOLUTION: Russets are for a 30th anniversary. 50th anniversary would be fingerlings.

PROBLEM: I don't know what to say.  I feel like I've broken down so many of your emotional barriers today and, being your mechanic and all, I haven't even begun to touch your car.  This is momentous.

SOLUTION:
You've made me realize that my whole life has been nothing but a lie!
