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.

Q: Context: 'Ok so I propose 2 water for me, 1 for you. 2 food for you, 1 for me. Firewood would be, 2 for you, 1 for me? Please give me your opinion if you want to reverse any of that.' 'That would work, the extra firewood would offset the need to have water on hand when I can boil it.' 'Just take one more minute to make sure you are good with that and let me know. As soon as you are absolutely sure, I will send the proposal.'
Utterance: 'You need the water more I feel. I don't want to slight you for having a medical condition and I know how the heat can take a toll on people. I think that proposal works well enough as I'm getting extra firewood and food. '

A: No
