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 vouch-fair strategy, otherwise output No. vouch-fair is a selfish negotiation strategy. It is used to call out fairness for personal benefit, either when acknowledging a fair deal or when the opponent offers a deal that benefits them. This can be through an explicit call out or can be implied.

Ex Input:
Context: 'That's awesome! Since we have the basics, would you be willing to swap 3 packages of food for 3 packages of water?' 'We will need two food so we can fill their bellies, but I will be glad to offer you all the firewood since I can use my axe and get wood for us.' 'Absolutely understand. How does this deal sound: you will get 2 food, I will get 1. You will get 3 water, I will get 0. You will get 0 firewood, I will get 3.'
Utterance: 'That is a very fair deal. I am glad we could work this out.'
