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: 'you pointed out that we will need more!  😮 i will take 2 waters' 'I didn't know you had supplied everyone with water before the trip. I was merely trying to look out for your needs, but you said you didn't need them!' 'I am giving you a lot of food. You are being unreasonable and backtracking. You are getting some of everything with my offers, and there are only two of you.'
Utterance: 'You said you only needed one food package and two bundles of firewood for your group together tonight and had plenty of everything else. You're the one insisting you need more now. This is my son's first camping trip and we're bound to lose supplies and waste them. Your group is trained and prepared.'
[A]: Yes


[Q]: Context: 'No, I definitely need more water than that for my hikes,  ' 'can i get 3 food, 1 water and 0 firewood then?' 'I think that will work for me.  '
Utterance: 'perfect'

[Q]: Context: 'Ha, woah that's exotic! I'll need some firewood as well, but maybe not as much as you! I'm planning on going hiking a lot, and will need some extra water, as, again, ill be hiking a lot' 'I will offer 3 water to you! You will maybe need more food with that much exercise? How about 2 food? I really need that extra firewood. Remember that the Catskills probably has some extra wood around.' 'That works for me, you can have the firewood then!'
Utterance: 'Alright that sounds great. '
[A]:
No
