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 is your camping trip going?' 'It's going good we could use some more supplies such as food and firewood, though.'
Utterance: 'Same here haha. Is water your lowest priority item too?'
answer:
No


question:
Context: 'Yes! Hope for lot of fun. Is there any special deal can you offer for maximum order.' 'What item are you looking for the most of?  ' 'Water and food is on high need than the firewood. Expect for the best combo for food and water.'
Utterance: 'I brought plenty of water.  I think I could give you all 3 water. Food is what I need the most of so wonder if I took 2 packages of food and left you 1?'
answer:
Yes


question:
Context: 'Nice! What are your highest priority items?' 'We need a moderate amount of everything and I think we can work something out successfully.' 'got it, OK I'll start then. I'd like at least 2 firewood'
Utterance: 'Okay. we brought some of our own food so I don't need much of that either.'
answer:

Yes
