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: 'Good!  How are you?' 'I'm doing well! Almost ready for my camping trip. Need some more supplies though.' 'Which supplies do you need?'
Utterance: 'Well, I really need water in case we get really thirsty from hiking. I also need firewood in case it gets colder and we need more. It would be cool to have more food added for dessert like s'mores, but it's not really necessary.'
answer:
Yes


question:
Context: 'Okay, well firewood is also my top priority since it will be so cold tonight.  But I would be willing to take only 1 firewood (and give you 2) as long as I got 2 foods and 2 waters ' 'Thank you for the offer on firewood.  I think that sounds fair.  However, I really would like at least 2 waters as well. ' 'Hmm unfortunately I can't budge since I would be accepting less of my top priority item.  It sounds fair to me though; I'd get 5 items in total but less of my top priority and you would get 4 items in total but more of your top priority'
Utterance: 'Well, how about if I take 2 firewoods and all of the food and you can have all of the waters? I have a device that I can make clean water, but will need more calories to do so! 🙂'
answer:
Yes


question:
Context: 'Hi. I'm most interested in water. What's your highest priority?' 'I really need water too. I have a young baby and will do a lot of washing.' 'Okay. I'm not especially worried about food. What's your lowest priority?'
Utterance: 'I have enough food too. Can I take 2 water, 1 firewood and 2 food?'
answer:

Yes
