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: 'Oh yes, sorry I am so caught up with my wound I completely forgot about that. I can spare 1 firewood so you would get 2, do you think you could spare another water in exchange for the wood?' 'i cant unfortunately i really need the two water im sorry. ' 'im so sorrry unfortunately i am in dire need of two wood we are in a very cold climate'
