Teacher: Given a negotiation between two participants, answer 'Yes' if both participants agree to the deal, otherwise answer 'No'.
Teacher: Now, understand the problem? If you are still confused, see the following example:
THEM: i need the hats and the ball  YOU: i can give you one hat and the ball. i want 2 books and 1 hat  THEM: i have to have both hats and the ball or both hats and a book to make a deal  YOU: sorry, i won`t make a deal without a hat  THEM: if you take 1 hat i have to have everything else  YOU: sorry can`t do  THEM: no deal  YOU: yesh no deal, sorry  THEM: no deal  YOU: no deal.
Solution: No
Reason: Both participants do not agree to the deal, so the answer is No.

Now, solve this instance: THEM: i will give you all the balls in exchange for the books and hat.  YOU: i could really use the books and the balls. i run a preschool and could use those items.  THEM: that wouldn't work for me. i can give you both books in exchange for the balls and the hat.  YOU: i wanted the balls also.  THEM: i understand what you want, but we're trying to reach a compromise. do you ahave a better offer?  YOU: i will give the hat in exchange for the books and the basketballs.  THEM: no deal ; i'm losing out completely with that.  YOU: how is that? it is a completely even trade.  THEM: our point values are quite different, i assume. i will compromise on 1 book and 1 hat, leaving the rest to you.
