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.

Utterance: 'Hello, I think that my first deal will be fair 🙂'

Answer: No


Question: Context: 'I have definitely been there before! With taking all the kids I'm worried about them getting dehydrated. I also have a 7 month old that needs water to make her bottles! I was hoping to get 3 extra packaged of water for sure. ' 'That is one of my fears as well. Does you seven month old breast feed? I am hoping for the water as well. I would love to give them to you if I had extra. Is there anything else you need?' 'No they don't ☹️ She is starting to eat a few solid food items. So if I had some extra food that would help. I think if I had 2 waters, 2 food, and 1 firewood to be able to cook and keep things clean I would have enough. '
Utterance: 'I can give you 2 waters, but I would need all the food because my group is bigger. You can have two firewood.'

Answer: Yes

Utterance: '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.'
