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'm good as well, trying to plan my camping trip for the weekend. Do you enjoy camping?' 'I do but it's hotter than I expected. Probably gonna drink a lot of water.' 'It pretty cool where I live so I don't need many water. But I do need a lot of food and firewood. Have a huge family and we do a lot of grilling. '
Utterance: 'I would give you all the wood if I could have all of the water.'
