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.
One example: Context: 'Well maybe we can work something out between us.  Our food and water was in the bags they loss so I really need those.  Do you think you could make do with 1 food and some water?' 'I really need 2 foods. I can do with 1 water or if you are in a giving mood then maybe I can have 2 waters?' 'Looks like we both really need the food.  If you get 2 food I would need 1 food, 2 water and 3 firewood. '
Utterance: 'Since you will get all the fire would do you think I could have 2 foods and 2 waters. You would get 1 food, 1 water, and 3 firewood. You seem like you are a great outdoor person that I would think you would be able to catch some fish to cook with the firewood.'
Solution is here: Yes
Explanation: Correct. The participant tries to undermine their opponent's needs by mentioning that the opponent can just fish for food.

Now, solve this: Context: 'we want to explore the animals in the area birds and just enjoy all the nice views.' 'Cool, that sounds very nice and relaxing 🙂. It kinda sounds like my husband, he likes to do things like these with no concrete plan and just decides on the spot what he wants to do. The only problem with it is that he dumps all the planning on me so I have to make sure I have extra of ANY possible idea he has.' 'Yes we always get stuck making the plans so can I have 2 firewood and you get 2 food and 2 water? Please respond a little faster with your messages that would be very nice'
Utterance: 'Unfortunately, I need the firewood to make campfires. Since you are planning to cook a romantic camping meal, don't you need food?'
Solution:
Yes
