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.

Example Input: Context: 'I think we are getting very close to a good deal. Would you be willing to give me ONE firewood in case the stuff I have gets wet?' 'I strongly agree and shall we call it a deal now? 🙂' 'Like I said, we are close but I really would feel better with just one of the firewood. I'm afraid of not being able to build a fire. If you really need the firewood, however, then I would take one additional item of EITHER the water or food instead.'
Utterance: 'And like I said, I strongly agree and you can have ONE firewood now. Deal close ?'
Example Output: No

Example Input: Context: 'Are you really exciting about camping trip?' 'yes i am really happy about that camping trip? you also' 'yeah. i really worry about my firewood. because i don'y have any back up for firewood. will you please provide all firewood to me'
