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: what is your wish?  YOU: one ball and two hats?  THEM: i would like 1 ball 2 books  YOU: how about 1 ball and 1 book  THEM: 1 ball, 1 book, 1 hat for me?  YOU: no 1 ball and 1 book for you.  THEM: guess this is the best i'll get.  YOU: deal?  THEM: deal  YOU: ok.
Student:
No
