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.

Ex Input:
Context: 'Can you help out? I can easily dehydrated can you give all the water packages to me?' 'I can spare a little as I am currently taking medication that requires me to drink a lot. I can give you 2 bottles of water if you can give me 3 firewood' 'I can't give you all the 3 firewood. We can share them. I can give you 1 firewood? Because I am too scared about dark. ☹️'
Utterance: 'I could give you 1 water for 1 firewood, most of my firewood got wet so is almost useless . Would you perhaps except some food for another unit of firewood?'

Ex Output:
No
