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.

Input: Consider 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.  '

Output: No


Input: Consider Input: Context: 'Okay, well if you need water and firewood, that only leaves food. If you can part with extra food, here's what I'm proposing' 'Yes you can definitely have all the food. Maybe 2 firewoods and 2 waters for me?' 'Sounds good to me.'
Utterance: 'Ok great would it be ok if we have 1 of the foods?'

Output: No


Input: Consider Input: Context: 'Hey there how are you?' 'I am fine friend. I need a lot of firewood though. It is freezing' 'I definitely need firewood as well. We didn't anticipate it being as freezing cold as it is at night. There isn't much around us. We've also been using a lot of water, which we could use more of since we've been looking for firewood.'
Utterance: 'Your needs are like mine. I have a condition that require  me to shower quite often. It is a shame but if I do not shower for 3 hours I will stink.  '


Output: No
