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: Context: 
Utterance: 'how about I give you 2 waters and 1 food package in exchange for all your firewood?'
Example solution: 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.

Problem: Context: 'Yes! I am so on the same page as you. I want to be sure I'm set and prepared. 🙂' 'Would you consider letting me have 2 of the 3 extra firewood?  I have health issues and I get really cold sometimes.☹️' 'Yes, I think that would be very fair, since I don't have health issues myself. Would you allow me to have 2 of the 3 food items? I need energy for hiking. 🙂'
Utterance: 'That would be perfect.  I am a gourmet cook and if you would like me to help you prepare the evening meal, I would be very happy too.🙂'

Solution: Yes
