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: 'So I get only 3 packages? 2 food and 1 firewood? ' 'Do you need more firewood?  I could compromise there.' 'How about I get 2 food and 2 firewood? You can get all the water plus 1 food and 1 firewood? '
Utterance: 'Yes that sounds fair.  Deal.  '
Solution:
No
