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: 'Same here! Last time my daughter got dehydrated and it made her sick!' 'That sounds awful! 😮 Where are you going to be camping?' 'In Arizona, so I know it'll be hot. How about you? '
Utterance: 'Same! At least, I won't need firewood, because it will be so hot. I'm very worried about the water situation though. It's just going to be me out there and the only fresh water is at the base of the canyon, and that's a really long and dangerous hike down for one person.'
Example Output: Yes

Example Input: Context: 'Why do you have a risk of dehyrdation? Because I believe all people do but I do understand some people are at a greater risk then others. Tell me why you are at risk?' 'I have a medical condition that requires medication, and this medication requires me to drink an extra amount of water or else I will dehydrate. ' 'That is a problem. Does the medication require the use of fire or firewood as well?'
Utterance: 'No, of course not. You can have the extra of those if you'd like. It is really the water that is the most important to me. '
Example Output: Yes

Example Input: Context: 'I need a lot of food, because of how many people are coming now (like 3 times as many). Also, there's only one stream in the area and it's really far from our campsite, so it would be super inconvenient to have to hike there everyday to refill our canteens. We are in a forest though, so we should be good for wood. Since you can easily fish, what if I take 3 food and 2 water? You can keep all the firewood. 🙂' 'Well I have to have some food and I don't need all of that water.  How about I take 2 water, 1 firewood, and 1 food.  I do need the firewood to cook the fish but I dont need it to keep warm at night because I have hefty sleeping bags that work excellent in the cold.' 'That could work, but I'm still a little worried I won't have enough food for 6 people. How long are you guys going to be camping for?'
Utterance: 'I will be camping for 3 day so I gotta have some food.  Although, I do understand your situation.'
Example Output:
No
