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: '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


question:
Context: 'Camping yay!' 'Hello! how are you? hoping today is finding you well. I was wondering if I can get all 3 of your Firewood, I am willing to trade for all 3 waters. I am camping with 40 kids, its our annual youth camp. its rainy season too, I really want to ensure I have enough dried wood with us. need lots of firewood for the amount of cooking I will be doing, keep the camp warm, and specially to keep those pesky bugs away. what do you think?'
Utterance: 'I could really use the firewood too, it will be very cold where we are going. Since it will be cold, we will not be drinking much water. How about 2 firewood for you, 3 food for me?, '
answer:
Yes


question:
Context: 'Can i kindly know your preferences please?' 'Well, I'm kind of low on water, so I'd like to get as much of that as I can. I'd like to go hiking and I don't really have enough water for a long trip. What about you?' 'Ohh nice.I also have the same issue around here.The thirst for water is growing high than ever due to drought'
Utterance: 'Well, that's a bummer. How are you set for food? While I wouldn't mind a bit more, I'm in pretty good shape there, so I'd be willing to trade it for water. I'd hate to leave without getting a good hike in.'
answer:

Yes
