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 uv-part strategy, otherwise output No. uv-part is a selfish negotiation strategy. It is used to undermine the requirements of the opponent. For instance, suggesting that the opponent would not need more firewood since they already have the basic supplies or a suggestion that there might be a store near the campsite where the opponent can get the supplies instead.
question:
Context: 'I would really like to have 3 waters and 3 firewood because this is my first time camping and I don't have survival skills. ' 'You must be a comedian.  We will need to come to a compromise because there's no way that's going to happen.  I am like a water buffalo so I'll need at least two waters.  In addition, my family is from the South and will need firewood as well.' 'I can't swim too. I think two waters will help me to survive on this trip and I will need at least two firewood to make fish or other food items for my family. '
Utterance: 'You don't need this water to swim.  You can take two of the food if you're worried about food.  I will take two water and two firewood since I have a large family to nourish and keep warm.  Your initial suggestion of 3  waters and firewood is laughable.  Please provide a realistic compromise.'
answer:
Yes


question:
Context: 'Hmm.. well let's see! What is your second priority? I would be willing to give up all of that, if I could get at least 2 firewood. You're right, it sure does get chilly ☹️' 'What if I got 3 foods and 2 waters. and you got 3 firewood and 1 water. If I could get a little more food that doesn't need to be cooked over the fire I might be able to get by. And I'll need to buy more water so I don't have to boil it since I won't have much firewood. ' 'I would say that sounds like a good deal! I am a little worried about water though, there aren't any sources of water where we are going. Hmm..'
Utterance: 'I think having 3 packages of firewood will help! you can always boil water from a  fresh spring 🙂'
answer:
Yes


question:
Context: 'Would it work for you, then, to give me the three food and three water, and I can give you all of the firewood?' 'No. Because I brought a water purifier but don't plan on hunting or fishing. So I'd be willing to give up all the water but I want 2 of the food.' 'I see.  I also greatly need the extra food, as I indicated. Perhaps there are some convenience or grocery stores near your campground--you might then purchase extra food there and not have to carry it with you on your trip?  '
Utterance: 'I believe there won't be any convenience stores around to buy food, And I plan on staying out longer than you so I will need more food to last me, Do you need food or water more?'
answer:

Yes
