TASK DEFINITION: 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.
PROBLEM: Context: 'Ok, what would you counter offer with?' 'I would like all 3 packages of firewood and 1 package of food. You can have the rest.' 'Well, I would like at least one firewood, it is the thing I most need.'
Utterance: 'But you need firewood for leisure, whereas I need firewood for survival.'

SOLUTION: Yes

PROBLEM: Context: 'I enjoy camping as well. However, my campsite seems to be a bit chilly at night. I'd be willing to part with some firewood, yet I'd need quite a bit of food to compensate. I also have a stream nearby so water is plentiful if you need that as well.' 'I may be able to do something with regards to food. Do you have enough water?' 'I have more water than I need. How is your water supply?'
Utterance: 'I could use some more water as I get dehydrated easily. Since you have enough, I could give you and extra package of food for your water.'

SOLUTION: Yes

PROBLEM: Context: 'I would be ok with that but i will need some water and food as Im a little out of shape' 'I can get you one package of water and food, will that work?' 'how am i supposed to stay alive with one package of food and water im fat lol'
Utterance: 'I don't think you that fat, your lipids will help you stay warm and full out there, haha'

SOLUTION:
Yes
