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 no-need strategy, otherwise output No. no-need is a cooperative negotiation strategy. It is used when a participant points out that they do not need an item based on personal context such as suggesting that they have ample water to spare. no-need can directly benefit the opponent since it implies that the item is up for grabs.

Context: 'one food is not enough i am pregnant and i need to eat many meals' 'My friend is ill and needs to eat to survive. How about I take 3 water then and you can have 2 food and all of the wood?' 'sounds reasonable'
Utterance: 'Great! glad we could come to an agreement. May I ask why you are camping while pregnant?'
Output:
No
