Teacher:Given a negotiation between two participants, answer 'Yes' if both participants agree to the deal, otherwise answer 'No'.
Teacher: Now, understand the problem? Solve this instance: THEM: hi there! i'd really be happiest if i can have all 3 books and the ball.  YOU: i think we can reach a deal. i can give you the ball, but i need to keep two of the books.  THEM: how about i take two books, one hat, and the ball?  YOU: no. my best offer is to give you the ball, one hat, and one book. i'll keep two books and one hat. can we do that?  THEM: if i can keep both hats, i will agree to that.  YOU: you can keep both hats then, and i'll keep the basketball.  THEM: this is tough, because that would be unfortunately a very low valued deal for me. i imagine it would be for you as well, if we did it differently.  YOU: let's try to make us both happy here. i'll keep two books, two hats, and you keep the rest. deal?  THEM: so i take the ball and one book?  YOU: yes  THEM: alright, that'll be the best we can do.
