Detailed Instructions: 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.
See one example below:
Problem: Context: 
Utterance: 'how about I give you 2 waters and 1 food package in exchange for all your firewood?'
Solution: No
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: 'I know how to filter water so you can have all of the water. I would like as much firewood as possible.' 'me too. I don't care about water since we are camping near a river.' 'I would consider giving you all food and water if I could get all of the wood.'
Utterance: 'Oh really? I think I am able to do it without firewood then. The kids will be full and probably won't ask for smores'
Solution:
Yes
