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: 'Hello. I hope you are well. I would like to have all of the water, 2 of the firewood and 1 of the food. ' 'Hello. I'm actually not doing too well. There have been a few problems and I will need some of the extra packages. I'll need two of the waters, 2 of the firewood and 2 of the food.' 'I'm sorry to hear that you are not doing well. I've also have some issues. On the way up to the camp site, all of my clean water spilled in the car. I was really hoping to be able to get all of the available water. Why aren't you well? I hope it's not serious. ☹️'
Utterance: 'Oh, that's terrible. I'm sorry that happened. I need the water for my child. They seem dehydrated and disoriented. My husband has also caught a cold and has been having chills. I thought the extra firewood would help him feel better.'
Example Output: No

Example Input: Context: 'I am too. I am so looking forward to this. ' '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.☹️'
Utterance: '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. 🙂'
Example Output: Yes

Example Input: Context: 'Oh yeah, that's for sure. What camping item do you prioritize?' 'I'm going to need some extra wood because I'm somewhat injured and can't really gather more.' 'Oh, I see. Well, I personally need lots of water to stay hydrated since I drank a lot already.'
Utterance: 'Yes, that's important. I don't need much.'
Example Output:
Yes
