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: 'Hi how are you?' 'I am good. How are You.   I was just thinking about how I need extra water due to a medical condition.  How about I take all 3 waters?' 'I am okay. How about I give you one and half then I get some firewood from you?'
Utterance: 'No I need at least 2 waters.  But I am willing to give you all 3 foods, if I get all the firewood.  Does that work for you?'
answer:
No


question:
Context: 'not soo good, i am hungry' 'Uh oh. What are you preferences on supplies?' 'food, then water, then firewood, and yours?'
Utterance: 'water, food then firewood. It's really hot so I need to make sure we are hydrated. We forgot a bag of supplies that had mostly food so we really could use food. It's hot so firewood isn't necessary. If anything we can get it from around or on a hike.'
answer:
Yes


question:
Context: 'I have a great risk of dehydration.  I really need those 2 extra packages of water. You can have all the extra food.' 'Why do you have a risk of dehyrdation? Because I believe all people do but I do understand some people are at a greater risk then others. Tell me why you are at risk?' 'I have a medical condition that requires medication, and this medication requires me to drink an extra amount of water or else I will dehydrate. '
Utterance: 'That is a problem. Does the medication require the use of fire or firewood as well?'
answer:

No
