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.

[Q]: Context: 'Ya definitely. I need food and firewood most. What do you need?' 'I believe that we have the same priorities.  So we have a large family including children that need the food, but my wife also needs firewood due to poor circulation.  She is susceptible to frost bite and limb loss' 'Okay so how about one of us takes 2 of the food and 1 of the firewood, and the other takes 1 of the food and 2 of the firewood?'
Utterance: 'that sounds fair.  I will take 1 food, 2 firewood, and 2 water, thus giving you 2 food, 1 firewood, 1 water'
[A]: No


[Q]: Context: 'That will be very unfair of you. How am i going to survive without water or food?' 'You have food and water, this is just extra supplies' 'I know but with my condition i may not make it, especially without more water.😮'
Utterance: 'you can make water by boiling water with all that extra firewood you got'
[A]: Yes


[Q]: Context: 'If I take two waters, 1 firewood, and 2 food supplies, this will help me during the trip. It seems as if you are more skilled than I am on a camping trip. Please consider my request☹️' 'LOL - not a chance.  You're going to have to give me more than that.  I am more skilled and thus need firewood.  How about this...I will take 3 firewood and 2 food.  You can take all the water because you're so non-skilled in the wilderness. I am going to hunt for my food, but again I have a large family.  I am not considering your request  at all.  We will need to come to a decision relatively soon.' 'I understand your preferences. If I take all of the water, 1 firewood, and 2 food your family will still have the opportunity to have a good camping trip and I can learn to survive on this trip. Please consider my request again.☹️'
Utterance: 'Ok - you're not being reasonable at all.  If you're so incompetent at going camping, maybe you should stay home and I can take all the supplies. How's that for an excellent offer?  All for me and 0 for you.'
[A]:
Yes
