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: 'That sounds reasonable. I don't particularly need the food because I see that as more of a luxury but I could really use some more water. It's supposed to get really really hot on the weekend. 😮' 'I hear that. What do you think of if I take 3 of the food supplies and you can have two waters? ' 'That sounds like a fair compromise. I can get food by hunting animals, old school style. That would give you 4 total items. In that case it's only fair if I take all 3 of the firewood. 4 for me and 4 for you sounds like a good deal to me. 🙂'
Utterance: 'That sounds fair to me! I don't know the first thing about hunting so that would be a relief on me. We took a bunch of blankets so we'll be good on firewood.  🙂'
Example Output: Yes

Example Input: Context: 'you told me i not fair that why i told you are not fare,3 food for me  will give 3 firewood for me, give 2 water for me, other we can end the deal and both we can forget the bonus' 'ok' 'then what will do ? if you ok for 3 food for me , 3 firefor you, 2 water for me , for this deal we can go forward?'
Utterance: 'of course not. you just took all the priority items and you still want two water. I am going to make the last offer. you take two food and two water, I take one food, three wood and aone water. '
Example Output: No

Example Input: Context: 'Hello.  I am very interested in the firewood and would be very willing to forfeit all the water.' 'oh really.  i am willing to make a negotiation with you on that for sure.  where are you plannign to camp?' 'I'm camping near a natural spring and will have all the water I need.  How are you planning to eat?'
Utterance: 'i have some spare cans but i am not too worried about it.  its a low prioirty for me '
Example Output:
Yes
