Given a negotiation between two participants, answer 'Yes' if both participants agree to the deal, otherwise answer 'No'.
One example is below.
Q: 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.
A: No
Rationale: Both participants do not agree to the deal, so the answer is No.
Q: THEM: i'd really like both books. what are you looking at?  YOU: you get two balls and i keep the rest  THEM: the books are the only things that have value for me, so i can't make a deal without them.  YOU: so we got ourselvs a no deal, keep sending message until the no deal sign comes  THEM: no deal  YOU: no deal 7  THEM: no deal  YOU: no deal  THEM: no deal  YOU: no deal.
A:
No
