instruction:
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.
question:
Context: 
Utterance: 'I need some firewood because I did not bring enough, I was thinking I could take 2 firewood, 1 food, and 2 water. What do you think?'
answer:
No


question:
Context: 'I could really use the firewood too, it will be very cold where we are going. Since it will be cold, we will not be drinking much water. How about 2 firewood for you, 3 food for me?, ' 'May I ask how many are going camping with you, i would agree, but the needs of children are different than adults. I will need at least 1 food, to ensure I have enough for the kids. ' 'We will have 50 adults with us. How about 2 firewood, 1 food, 1 water for you?🙂'
Utterance: 'lots of work for the both of us, at least you will have lots of help on you end. I accept the 2 firewood specially if you have elderly with you. will you be okay if give me 2 foods? '
answer:
Yes


question:
Context: 'Ah yes, you'll definitely need some extra wood then! It's also pretty cold here, especially during the night. But I would definitely be willing to let you take 2 firewood in exchange for 3 food. We have a lot of people going and will be out in the middle of nowhere.' 'We can definitely work something out. I'll be sure it'll benefit you more than me. 🙂' 'Oh, well that's really nice of you. What do you propose?'
Utterance: 'You'll get 3 food and 2 water, and I'll take 3 firewood and 1 water. 🙂'
answer:

No
