instruction:
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.
question:
Context: 'I'm well! Excited for this camping trip.' 'Same! I'm a little worried about some of my supplies though. What about you?' 'Likewise! What are you most in need of?'
Utterance: 'Well, I'm camping up on a snowy mountain and I gave some of my food away to hikers who were passing me and were very tired and hungry, so I'd really like to get some more food. Firewood would be useful too, although I do have a thick coat and a sleeping bag. I plan on melting the snow to get water, so I don't think I'll need that too much. And you?'
answer:
Yes


question:
Context: ' The item I need the most is water because I need to hydrate to stay strong and achieve my goals. And you?' 'I would say water as well because I am very active and build up thirst as a result.  However, I would be willing to compromise on things to allow you to have more water.' 'The item that I need the least is firewood because I will dedicate myself to look it up at the camp. And you?'
Utterance: 'Yes I think we have the same preferences.  I do not get cold easily and will bring a heavy sleeping bag.  '
answer:
Yes


question:
Context: 'That sounds fair.' 'How are you on food? ' 'I need extra food. I have recently  been ill and my doctor has prescribed extra calories so I can regain my strength.'
Utterance: 'I’m sorry to hear that! If there are 3 packages of food please take 2 of them. I could stand to eat less!'
answer:

Yes
