Definition: 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.
Input: Context: 'Hi! I'm most interested in acquiring firewood, since I don't want my fire to burn out on the trip. What are you looking for?' 'I am also looking for firewood. Since I was a child i have always enjoyed camp fires. They mean a lot to me' 'Okay so we can think about splitting the firewood. 🙂 I'm also interested in water because I plan to do a lot of activities like hiking and kayaking, so it will be helpful for me to be able to hydrate more.'
Utterance: 'That is okay. What about i get 2 packages of firewood and then you get 2 packages of water. Is that okay with you?'

No
