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: 'Well I will definitely need 2 packages of food and 2 of firewood for survival.' 'I am definitely ok with giving you two of the firewood!!  Why do you need 2 packages of food?' 'I have a very fast metabolism and a dog to take care of. Thanks for the firewood.'
Utterance: 'Awe!  We have a dog as well, I love dogs!!  How about if you get 1 package of food, 1 water and 2 firewood?  Would that be sufficient for you?'
Output:
No
