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 is fair as there is no showers or sinks at my campsite so I am looking to take water :) ' 'We will likely also need to take water too. Need to be able to wash up.' 'That is fair, I also will need a good bit of firewood to keep warm as the campsite is in a colder area.'
Utterance: 'We dont care much for campfires. Leaves your cloths smelling for days!'
Example Output: Yes

Example Input: Context: 'Yeah, it's very sad these days' 'Then I got here and noticed I didn't pack my cooking sterno and critters go into some of my food☹️Kinda puts a damper on the trip.' 'Oh, i see. How about you get 2 food 1 firewood and 1 water. I need the extra firewood to stay warm at night'
Utterance: 'Yeah, that should work. I brought plenty of water and the critters left that alone. You planning to go out on the trails at all?'
Example Output: Yes

Example Input: Context: 'Oh my. A whole troop of girl scouts will probably be bringing lots of food with them to share, and plenty of people around to collect firewood. It is going to be just me and my son on this camping trip, his first time.' 'We were planning on getting our outdoor cooking badge by making  a big meal over the campfire tonight. I wll need plenty of firewood for that, but I can manage with only one food.' 'A lot of the firewood in my area is wet, so I'll need some extra packages of it as well. You're going to have a lot of people and a big fire, so it would be smart to keep a lot of water on hand to drink/in case the fire gets out of hand.'
Utterance: 'All my girls have brought canteens. I must have enough firewood if they will earn their badge. You can have one, but I won't be able to make due without 2.'
Example Output:
Yes
