Definition: 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.
Input: Context: 'I like the sound of getting the firewood, but I can't just accept no food or water.' 'I'll give you one of the extra food so you have a little extra to cook for everyone but I'm really gonna need all that extra water, it's going to be really hot this weekend and the folks at the capsite get to sit in the shade all day' 'Now we are making progress. But come on, I will need at least one water to make sure I'm hydrated. I wouldn't want to get heatstroke out in the woods.'
Utterance: 'The basic supplies include water, the additional supplies are just extra. Plus I think there's a well nearby!'

Yes
