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.

Example Input: Context: 'Hello, how are you doing?' 'I’m doing fine. How about you?'
Utterance: 'I'm doing well. I was hoping I could have the extra firewood because my group decided to camp for a few extra days and want to make sure we have enough'
Example Output: Yes

Example Input: Context: 'I would do this instead: 3 firewood, 1 water and 2 food.' 'That's not going to be a fair offer, you'll need to do better than that or I don't think we can come to an agreement' '3 firewood, 1 water, 0 food'
Utterance: 'so I'll get 2 water, 3 food and 0 firewood?'
Example Output: No

Example Input: Context: 'Can I get 3 packages of food?' 'What do you need it for?' 'I would like some extra food in case I get hungry.'
Utterance: 'Okay that sounds ok, I can do without the food. I also need two packages of water because it will be very hot out.'
Example Output:
No
