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.

Let me give you an example: Context: 
Utterance: 'how about I give you 2 waters and 1 food package in exchange for all your firewood?'
The answer to this example can be: No
Here is why: The utterance does not use the no-need strategy since it never refers to an item that the participant does not need.

OK. solve this:
Context: 'Hi - I can understand that. I have quite a few mouths to feed as well' 'hmmm, well what are you looking to get' 'Well, I think that for us staying warm is more important than having extra food. What if I took extra fire wood and you took extra food?'
Utterance: 'That could work, were not really looking to have a big fire'
Answer:
Yes
