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: 'Hi, how are you, ready for the big camping trip?!' 'Yep. I am excited. I could really use the decompression and time away from society. ' 'I agree, can't wait to unplug. As far as supplies go, I think its going to be hot and sunny where I'm going, wouldn't mind a bunch of extra water.'
Utterance: 'Water is extremely important to me too. I can give you 2 waters if you give me all 3 firewoods. '
Example Output: No

Example Input: Context: 'Great thank you. I am looking for primarily some firewood and food for my camping trip soon. ' 'I'm going camping too and also need food and wood, mostly food though' 'Okay I understand that! Is there a particular reason that you do not need much water?'
Utterance: 'I figure I could always get some at the stream 🙂'
Example Output: Yes

Example Input: Context: 'what is the next thing you need the most/?' 'firewood to keep the body warm ' 'so water, firewood and food for you, and water food and firewood for me. what do you suggest'
