Q: 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.
Context: 'I hello I need firewood to survive' 'oh my are you going somewhere cold? I could use the water, I am going on a charity event with kids from the Make A Wish foundation. Its going to be their first time!' 'Ok I will give you 3 waters if you give me 3 firewood'
Utterance: 'sure i can do that, what about the food then? how much food would you need for the tip?  can you hunt where you are going?'
A:
Yes
