Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Context: 'Yeah, I'm going to the desert so I'm hoping to have enough water. I'm good on food and I hunt for a lot of it anyways.' 'I've never been a good hunter. I wish I had those abilities.' 'I would part with all the food if I could get all the firewood.'
Utterance: 'That seems fair. How about water. How would that be split? I'm very concerned.'
Solution: Yes
Reason: This is correct since the participant points out that the proposed deal seems fair.

Now, solve this instance: Context: 'I am worried about water but also could use a little more food, just in case. I am looking forward to a nice campfire as well!' 'I know! Camping's so much fun! Where do you plan to be going?' 'We will be camping up north, nothing around for miles!'
Utterance: 'Ooh, that sounds like you're really roughing it! What kind of activities do you plan to do? I'm planning to really tire my kid out and do a lot of hiking. My husband's also excited to practice "survival skills" and wants to do a lot of fishing and foraging too.'
