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: 'Hello I need a lot of water to survive' 'I have a lot of water around me I can use. So I can give you a lot of extra.' 'Ok nice I will give you 3 food if you give me 3 water'
Utterance: 'OK, that works for me. But I would like a lot of firewood. I like to hunt and cook what I kill.'
Yes
The speaker not only states their need for firewood, but they describe their personal need for it by saying that they like to hunt and cook. Since the utterance describes a personal reason to use the firewood, it is an example of using the self-need strategy. Therefore, the answer is Yes..
