You will be given a definition of a task first, then some input of the task.
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: 'Good thanks! So I'm hoping I can get all of the Food, but am willing to negotiate on the other items. ' 'Ohh food?.Thats a very essential property over here.I mean very important.Do you really need it that bad?' 'It's my top priority, but if you need some, I'd need more water and firewood'
Utterance: 'It aslo my top priority but i would not if u give me 3 packages of water and  2 firewood in exchange for all food.Agree?'
Output:
No
