Q: 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.
Context: 'Great, that sounds good to me, are you okay with keeping all the food or would 3 be too much?' 'I'd be ok with keeping all the food. I do eat a bit too much and if for some reason I get lost it would be helpful to have!' 'I agree with that, so you would get the two water and three food and I would get one water and three firewood?'
Utterance: 'Yeah. If that's alright with you? It rained here recently but I bought a top of the line tent and sleeping bag so if I do run out of firewood I'll still be ok.'
A:
Yes
