Q: 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 self-need strategy, otherwise output No. self-need is a selfish negotiation strategy. It is used to create a personal need for an item in the negotiation, such as by pointing out that the participant sweats a lot to show preference towards water packages.
Context: 'fair enough, how do you want to split the water' 'I'm willing to trade off water if you need more of it! I'm really looking for food and firewood, but I'll take food over wood.' 'sounds good, how about i take 2 firewood, and 2 waters, and one food'
Utterance: 'Hmm if I give you two firewood, how much food will I get back? I'm only willing to do two for two.'
A:
No
