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: 'I will need food packaging as well, so unfortunately I cannot agree on you taking it all. I will need 2 of the food packages, 1 of the firewood, and 2 of the water as I want to ensure to feed/hydrate my family of 5.. Does this work for you?' 'I can't agree to this, as I have to feed my family with 7, so I would be needing 3 food packages and 2 water and 2 firewood. will this be agreed by you?' 'No, that will not work. That does not leave me with hardly anything to feed my family of 5 😮. I will not agree to you taking 3 food packages. I can agree to me taking 2 packages of food, 2 of firewood, and 1 of water.'
Utterance: 'In that case I can consider this 2 food packages and 2 water for me and the rest for you. will you agree to this?'
Example Output: No

Example Input: Context: 'I would also like a little extra food for my kids. Maybe we can split it somehow?' 'Ok, I am willing to give you one food, in exchange for two firewoods, that would mean you get 3 waters, 1 food and 1 firewood. you get 5 items, while i get 4.' 'If I only get 1 food, than I would like 2 firewood. So you get 2 food, 1 firewood, and 1 water.'
Utterance: 'No i do not need water, as i am camping near a potable stream. I would like 2 firewood. It is only fair that i get two firewood, since you are getting more supplies (5), i think i should be able to choose what 4 i should get.'
Example Output: Yes

Example Input: Context: 'hello. so what are you thinking about this whole situation?' 'Hey, I think that this is nice, we get to go camping and get extra stuff. But definitely need more food and firewood'
Utterance: 'Yeah, I think I'm okay with firewood, but I'd really like more food and water.'
Example Output:
No
