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: 'I'm also going camping with my two children and 2 of my nephews How would you like to divide the supplies?' 'Well what do you need the most of?' 'I need the most firewood due to a congenital issue that results in us having poor blood circulation to our extremities, thus making them susceptible to frostbite in the cold!'
Utterance: 'Oh dear, that sounds serious! Well I need food the most because my children eat sooo much and I don't think I packed enough. How about I'll give you all my firewood in exchange for all your food?'
Example Output: Yes

Example Input: Context: 'We wantto do a lot of hiking on our trip and therefore I need extra water to make sure we stay hydrated. '
Utterance: 'hi! thats awesome i am going camping too, but not a lot of hiking. I am bringing 2 teenage boys so food will be very important for us'
