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 Q]: Context: 'Okay, so you can take all the firewood and I take all the food. I will also need at least two waters because I had a limited supply at home.🙂' 'no, i will need 2 water because i need to drink it and there not much water around me' 'Please work with me. I will need plenty water to make it to the top of the mountain.'

[EX A]: No

[EX Q]: Context: 'well then give me 1 firewood 2 food and 2 water?, then you have 2 firewood so your boy can practice' 'What I don't understand is that you requested I respond quicker to your messages, yet you do not respond with much detail or discussion.' 'i want my share as well I give you 2 wood 2 water  and one food '
Utterance: 'But why should I share with you? You requested that I respond quicker to you yet all I know is that you will be camping with only 1 other person :(. All you plan to be doing is leisurely looking at bird-watching. Will you be really using all of the items? '
