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: 'Yeah! I usually camp by the lake so I can use the lake water when I need extra water.' 'I can understand that. I have done that before. Also done winter camping next to a lake where we tried ice fishing.' 'That sounds like fun. I checked my list and it looks like I am short on firewood however, would you happen to be able to spare some?'
Utterance: 'Yeah I could supply you extra firewood. I would like some extra food if you could spare that.'
Example Output: No
