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: hi, i'd like 1 hat and 2 books. YOU: i want the hat and ball THEM: no, i really need the hat. YOU: i can give you the hat if i get the rest THEM: no, i really need the hat and 2 books to have decent points YOU: 1 hat or the rest are the same amount of points for me, and its low THEM: same here. no deal. YOU: well if were evenly split it probably is a stalemate on who gets less THEM: true. we can agree on the no deal then. YOU: ok.
Student:
No
