Given the task definition and input, reply with output. 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: 'What are you most interested in getting?' 'I think food is my highest priority, What about you?' 'Food is also my highest priority, but firewood is also pretty close for me.'
Utterance: 'Would you be willing to take more firewood for less food?'

No
