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.

[Q]: Context: 'I am just concerned that only 1 firewood might make it so I'm too cold to function. ' 'If you boil the water above the fire, it will provide additional heat over time.  You would also be able to make tea, which would warm you up from the inside as well, better than any fire would.  That would probably be most beneficial to you.  I really do need the 2 firewood if there's any chance of making a bonfire for my party.' 'I am allergic to tea and coffee. I wonder if the smaller fire would be more quaint for everyone to sit around. '
Utterance: 'It really wouldn't do the job that well at all.  You could always prepare hot cocoa or use your share of the food to make a warm stew.  I really do need at least the two firewood and a couple of food.  You can have all the water to make a hearty and hot stew to get your through the night, though.'
[A]: Yes


[Q]: Context: 'oh nooo, that's terrible. do they know where they left them?' 'I think they went to Chicago.  I really needing replace our lost water and sleeping bags.  I see there are some extra supplies to share.  I could really use the water and firwood.  🙂' 'oh yeah, you definitely do. we have all of our stuff and mostly wanted to hike and have picnics during our camping trip '
Utterance: 'Great. If you mainly doing picnics do you want 3 Food?   I could use the the supplies.  🙂'
[A]: Yes


[Q]: Context: 'Can I have 2 firewood 2 food and 1 water I think this would be enough' 'I have a Family too, I can compromise on either only one of Firewood or Food, please give a thought.' 'This is way too unfair, my friend'
Utterance: 'ok how about I give you 1 firewood, 2 food, and  1 water '
[A]:
No
