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: 'Alright. I have a  feeling we will have a deal then. How about you give me two water for a firewood?' 'that sounds like a plan' 'how many firewood you need? Maybe we could also exchange one food for one more firewood?'
Utterance: 'I would appreciate that, I was thinking of asking that! I would not require much in the way of extra food or water but the fire wood would be important!'
A:
Yes
