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 am doing well, how about you? It is another hot July day.' 'I am doing pretty good. I am going camping this weekend and just double checking to see what extra supplies I need' 'I love camping, have not gone in a while. Have you ever camped by a lake?'
Utterance: 'Yeah! I usually camp by the lake so I can use the lake water when I need extra water.'
A: 
No
