You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
Given a negotiation between two participants, answer 'Yes' if both participants agree to the deal, otherwise answer 'No'.

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
Why? Both participants do not agree to the deal, so the answer is No.

New input: THEM: if i can have the ball and the hats you can have the books  YOU: that's funny because i need the ball and the hat  THEM: okay then lets split the difference if i can have the ball and two books you can have the hat and one book  YOU: that definitely won't work. i need atleast the ball and 2 books.  THEM: i need the ball or i can not make a deal  YOU: ok, well either i get all the books and the hat or it's a no deal.  THEM: okay we can make that deal. i will take the ball and you can take the rest.
Solution:
Yes
