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.

Ex Input:
Context: 'No I need extra food too. I cannot let my children starve and you cant let your children go thirsty. So if you cant agree to share the food i will walk away from the deal.' 'There is no point in walk away. This deal should be done mutually and beneficial for both. So its better I will take 2 food packages, you can take 1 food package, 2 water and 3 fire wood .Hope this will definitely work for you.' 'No i absolutely need 2 food packages and 1 water. How about we do it like this... You take 1 food package, 2 waters and 2 firewoods. Does that work for you?'
Utterance: 'Sorry to bother you, I don't need anything other than food package. So better you could give me 2 food package and take 3 water and fire wood. Please consider this deal.'

Ex Output:
No


Ex Input:
Context: 'my people feel like they need 1 extra of something or else they will throw a fit ☹️' 'No fits!!  They're getting that extra water they really want.

Utterance: 'I think taking 1 extra water, for safety purposes will be OK for us and your group will get that.  I am going to submit a GREAT offer that is mutually beneficial.  '
