You will be given a definition of a task first, then an example. Follow the example to solve a new instance 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:
Utterance: 'how about I give you 2 waters and 1 food package in exchange for all your firewood?'
Solution: No
Why? The utterance does not use the no-need strategy since it never refers to an item that the participant does not need.

New input: Context: 'My main objective for the camp is water, since I have a large family and the amount of water they give in the camp is very small for all my family.' 'I need water also but firewood is my second highest priority item. Maybe you could take more of the water and I could take more of the firewood.' 'I find it a good deal, however before making a deal, I like to talk to people, get to know them better. I plan to go to camp with my family: my wife, my four children and myself. Are you going with your family?'
Utterance: 'Yes, I am going with my wife and two teenage sons. We are planning on doing a lot of fishing!'
Solution:
No
