Detailed Instructions: The input is taken from a negotiation between two participants who take the role of campsite neighbors and negotiate for Food, Water, and Firewood packages, based on their individual preferences and requirements. Given an utterance and recent dialogue context containing past 3 utterances (wherever available), output Yes if the utterance contains the no-need strategy, otherwise output No. no-need is a cooperative negotiation strategy. It is used when a participant points out that they do not need an item based on personal context such as suggesting that they have ample water to spare. no-need can directly benefit the opponent since it implies that the item is up for grabs.
See one example below:
Problem: Context: 
Utterance: 'how about I give you 2 waters and 1 food package in exchange for all your firewood?'
Solution: No
Explanation: The utterance does not use the no-need strategy since it never refers to an item that the participant does not need.

Problem: Context: 'No i absolutely need 2 food packages. So if you cannot agree to take 1 food 2 water and 2 firewood i will walk away.  If you have children with you would would also need water which you are not asking for. ' 'Yes I too have children so only I am considering 2 food package, 1 water is enough for me and I dont need any firewood. So please accept this deal' '😡 I am walking away if i cannot get 2 food packages 1 water and 1 firewood. That leaves you with 1 food 2 waters and 2 firewoods. This is a good deal for you concidering that you havent been asking for water for your children until i mentioned that you need water for you children. Do you agree??'
Utterance: 'I already mentioned that 1 water is enough for me.But food is my only priority for my children so you please consider this and help me in this.'
