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: 'Hi! I am interesting in claiming all 3 of the water, as well as 2 firewood and 1 food. Does this work for you?' 'No I need more firewood' 'Okay, can I ask why the firewood is important for you? 🙂'
Utterance: 'You can find more wood in the forest but I'm going somewhere where there's not a loot of trees ☹️'
A: 
Yes
