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.

Ex Input:
Context: 'Wow, that's amazing. My parents took me camping when I was young. Now we going hiking every other weekend. What do you plan on doing?' 'That sounds like so much fun! I hope we get to hike some. I have my four month old baby with us which is exciting. I'm worried I didn't bring enough water for his bottles, though.' 'That sucks, you need to be hydrated. What supplies do you require? My family loves to grill, so we do require food.'
Utterance: 'Grilling is so much fun! We left our grill at home so we can't really do that. I will trade you some food for some water if you would like?'

Ex Output:
No
