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: 'I recently bought two new puppies, and they are coming on the trip. I could really use the extra water for them!' 'Awww. That sounds reasonable to me. I'm hoping to have a birthday dinner for my dad on the trip, so I'd appreciate some more food and a little more firewood.' 'Happy birthday to your dad!! You can have all of the food if I can have all of the water. 🙂'
Utterance: 'That'
[A]: No

[Q]: Context: 'I am really bad at cooking so will probably need an extra good just because I'll ruin one of the 3. Plus Im bringing 2 dogs they can eat the bad food I make 😮 I dont plan on hiking much so how bought I keep all 3 foods, and you keep all 3 waters and we can split the firewood. 2 for me, 1 for you. Great deal!' 'i too i am bad at cooking and i will spend a longer time in the woods so i will need atleast 2 foods, 2 firewood and 1 water' 'But I have more mouths to feed here so I will give you one of the foods, but then need 2 firewood and then take back 1 of the waters. '
