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.

Example input: Context: 
Utterance: 'how about I give you 2 waters and 1 food package in exchange for all your firewood?'
Example output: No
Example explanation: The utterance does not use the no-need strategy since it never refers to an item that the participant does not need.
Q: Context: 'Hello.  I am very interested in the firewood and would be very willing to forfeit all the water.' 'oh really.  i am willing to make a negotiation with you on that for sure.  where are you plannign to camp?' 'I'm camping near a natural spring and will have all the water I need.  How are you planning to eat?'
Utterance: 'i have some spare cans but i am not too worried about it.  its a low prioirty for me '
A:
Yes
