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: 'I'd like to have 2 extra packages of water and firewood.' 'I see. And I would like 2 extra packages of Food and 2 packages of Water as well.' 'I have a great risk of dehydration. I really need those 2 extra packages of water. You can have all the extra food.'
Utterance: 'Why do you have a risk of dehyrdation? Because I believe all people do but I do understand some people are at a greater risk then others. Tell me why you are at risk?'

Ex Output:
Yes

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. I am sure they'll be OK with giving a group with kids a little extra firewood to make this camping trip awesome for them' 'Okay if they get 3 water they are good with that allotment for the others'
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. '

Ex Output:
No
