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 am ready to go camping. I understand there might be some disagreement around the additional supplies we each can choose from?' 'There could be.

I have a medical condition - type 1 diabetes - that makes it important to bring extra water and food. I'd like to request more of those two items.'
Utterance: 'I don't have a problem with you having extra water.  I'll give you all the water, if I can have all of the firewood.'


Output: No
