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: 'I do need some food. I would like to get at least 1 food. You can still get 3 firewood.' 'I could use water as well, so I could get 1 water, 2 food and 2 firewood' 'I am good at making fire and have a starter so I can give up all the wood.'
Utterance: 'I still need 1 water, don't have a water purify kit. ☹️'

A: No
