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.

Question: Context: 'Hello! And happy camping! 🙂 To start off, I am thinking that I will need at least 3 firewood, 2 water and 1 food. Last time my axe broke and we ran out of wood! What do you think/need?' 'I also was really needing some firewood. It's supposed to get pretty cold at night where we are camping and I need to make sure I can keep my kids warm.' 'Hmm.. well let's see! What is your second priority? I would be willing to give up all of that, if I could get at least 2 firewood. You're right, it sure does get chilly ☹️'
Utterance: 'What if I got 3 foods and 2 waters. and you got 3 firewood and 1 water. If I could get a little more food that doesn't need to be cooked over the fire I might be able to get by. And I'll need to buy more water so I don't have to boil it since I won't have much firewood. '

Answer:
No
