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: you can have the hat and two balls if i can have the book and two balls  YOU: i'm tempted to say yes but i think the system assumes i'm giving in too easily if i accept right away, so this is a filler line  THEM: are the balls valuable to you?  YOU: like i said, i'm fine with your offer but the system keeps warning me not to accept right away. but the answer is yes, i take hat and 2 balls  THEM: sounds good.
A:
Yes
