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: 'Farther. I'm going so far north that we'll be passing over the north pole and keep going into Siberia.' 'That sound cool, I mean cold. 🙂' 'It will be. And I'm grateful that you recognize the need! Will you do me a solid by permitting me to have these provisions?'
Utterance: 'I can give you 3 firewood, but only 1 food and no water.'
Example Output: No

Example Input: Context: 'Oh, I see what you did there. No problem I have plenty of firewood for you buddy. 🙂' 'Great! What extra supplies would you like to bring?' 'Since it's hot there, I get thirsty and dry real quick. 😡'
Utterance: 'Oh ok, well I plan on bringing some juice, beer and other drinks. So I could spare some extra water. And I am pretty good at fishing, so I won't need much food either'
Example Output: Yes

Example Input: Context: 'I just want to make sure I understand you I get 2 waters and 2 firewood and 0 food. ' 'That's right. Since you would be getting food from your sister, while I am camping alone, you would be getting more food pretty soon. ' 'umm. I think the best and fair deal is a complete swap of water for food and you get 2 fire wood. '
Utterance: 'Since the food can have some water and moisture in it, let's do 3 waters from me for your 3 food. How does that sound?'
Example Output:
Yes
