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: can i have ball and 2 hats?  YOU: yes to the ball and even a book, but i must take umbrage at relinquishing any of the hats  THEM: book is 0 for me. how about ball and 1 hat?  YOU: it is not ideal but a reasonable request and i will agree  THEM: thanks.
Solution:
Yes
