Detailed Instructions: 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: 'Well I had a really great day fishing today and I would like to have some extra firewood so I can cook all of this fish.  How about I take the 3 packages of firewood and you can keep 2 additional food packages in return.' 'You really did have a good day didn't you! Sounds like fun. How many fish can one person eat? If I don't have the extra firewood I'm going to be really cold tonight. ☹️' 'I am here with my family and we love to eat fish.🙂  Maybe if you spend tonight sleeping in your car or camper I can keep the fire wood. In exchange I will give you the 2 additional food packages and all 3 of the water packages. It's only for 1 night.'
Utterance: 'Why would you want to give up all that water? You're going to need extra water for your family to drink. All the sodium in the fish is going to make you all thirsty!'

Yes
