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 other-need strategy, otherwise output No. other-need is a selfish negotiation strategy. It is used when the participants discuss a need for someone else rather than themselves. For instance, describing the need for firewood to keep the kids warm.

Input: Consider Input: Context: 'I would still like at least 1 package of the food please.  There has been a lot of rain in the area, but I think some poisonous mushrooms maybe prevalent in the area, so to be extra cautious I would like a little spare food on hand.' 'You don't have to eat the poison mushrooms. You can catch some fish from the river or hunt for small animals.  You have all of the firewood so cooking the food should not be a problem.' 'I won't willingly eat the poisonous mushrooms, but it could be very hard to tell the difference from safe and toxic ones.  I understand you will be staying in your area for a few extra days, but can you catch fish or hunt for small animals in your area too?'
Utterance: 'I do not have any extra firewood to do so.☹️  So if I can keep 1 package of firewood so I hunt and cook the fish.  I will give you 1 package of the food.'

Output: No

Output: Yes
