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: 'Well I think we can make a good deal then.  How many packages of food would you want?' 'Could we each do 3 of what we need the most? I get three food and you get three water? How do you propose splitting up the firewood?' 'We can do the 3 for 3 trade.  That works perfectly!  Its' going to be cold at night where I'm going.  What's it like where you're heading?'
Utterance: 'It's going to be pretty warm where I'm going, but it's also variable. How do you feel about you get 2 wood and I get 1?'
answer:
Yes


question:
Context: 'I have a medical condition that causes my veins to close up when I get too cold. I will thus need the 3 firewood.' '☹️Oh, that sounds awful. Are you sure you need all three packages of firewood?'
Utterance: 'I might be able to get by with just two... I'm on a diet though, so I don't need as much food.'
answer:
Yes


question:
Context: 'your dogs could probably hunt for something for you guys. and i would be in the would for a very long time ' 'My dogs are like 12 and 15 pounds.  Hopefully they don't get eaten themselves. What about 2 foods, 2 firewood and 1 water for me.  😮' 'hmmmmm not possible. i need the same exact thing. what about i get 2 foods, 1 firewood and 2 water☹️'
Utterance: 'If you take 2 foods, 1 firewood, and 1 water that's a deal.  Otherwise I need the 2 foods, 1 firewood, and 2 water.  '
answer:

No
