Given a negotiation between two participants, answer 'Yes' if both participants agree to the deal, otherwise answer 'No'.

Let me give you an 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.
The answer to this example can be: No
Here is why: Both participants do not agree to the deal, so the answer is No.

OK. solve this:
THEM: would you accept one basketball?  YOU: no. i want the hat and both balls.  THEM: how about i give you both balls and one book  YOU: i'll take the hat, one ball, and one book.  THEM: i can offer you everything if you give me the hat  YOU: i want the hat, and will not give it up.  THEM: i can not make an agreement with you unless i get the hat  YOU: as a last resort. i'll give you everything if i can have the hat.  THEM: i will not accept anything other than one hat  YOU: unfortunately i don't think we're going to be able to make a deal then.
Answer:
No
