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: 'Yes. Hoping we can make a good deal.' 'Me too!  I'm hoping for two food items and one water.  I'm diabetic so if my blood sugar drops, I may need the extra carbs.  And water because water is important! 🙂 ' 'I prefer two water and one food. I can understand why you need the extra food items. I'm not much of a snacker but do drink a lot of water all the time. Keeps me from eating more!🙂'
Utterance: 'Lol, it seems it was easy for us to come to a deal!  I'm super bad at drinking water (trying to get better) so I don't feel I'll need as much.  Do you want all of the firewood or should I take one and you take two?  '
Example Output: Yes

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: 'Hey there! I'm assuming you enjoy going camping?' 'Yes I do, I am going this weekend. Are you going camping too?' 'Same! I try to go every other weekend.'
Utterance: 'Oh cool. What supplies do you prefer to take the most of?'
Example Output:
No
