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.

Context: 'I think we have a deal' 'ok i am accepted deal' 'Thanks'
Utterance: 'ok thank you'
No
The speaker is simply thanking the other participant for their agreement, and does not mention anyone else's need.
Since the utterance in this case does not use the other-need strategy, the answer is No.'.
