Teacher: 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...'. 
Teacher: Now, understand the problem? If you are still confused, see the following example:
I just want to say if this does not work out I promise to to personally show up to each of your homes and apologize for my life not working out the way that it should.
Solution: You know what, come tell us at the community pool.
Reason: This is a good response. Because it accepts in indirect way the input sentence and supports it.

Now, solve this instance: The local news reports are commenting on how incredibly strange for a high school to poltergeist in on itself.
Student:
Are you talking about the movie poltergeist? I haven't seen that, so don't spoil it.
