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: 'Great! I'm very excited to go camping, how about you?' 'I am! Now, I need a lot of firewood because we were planning on burning some earlier (to start cooking meals and such). I also need some extra food in case bugs come and eat some (like last trip, ugh). How about I take 2 firewood, 2 food, and you take 3 water, 1 firewood, and 1 food?' 'Would you be open to taking 1 less firewood, I would give you 1 food for it. The weather is supposed to be extra chilly and we did not bring warm enough sleeping bags so we need the extra firewood to avoid freezing to death!'
Utterance: 'No, I would need more water if I were to take that deal.'
Example Output: No

Example Input: Context: 'Yeah same here. The kids are really looking forward to it.' 'Same, my kids are as well! They have not been camping before. They are super excited about the campfires. I'm worried I don't have near enough firewood though. I just found out you can't cut any trees down where we are staying. ' 'oh no I'm so sorry to hear that. My kid are looking forward to the ghost stories around the campfire.'
Utterance: 'My kids will enjoy that as well. I'm hoping I can pack several extra things of firewood. If I could get 3 more packages I would feel better about having enough firewood to have campfires during the evening and to cook on. '
Example Output: Yes

Example Input: Context: 'Hello! I would like make a deal with you on firewood, water and food! Are you interested in any items ?' 'Yes, I'd definitely be interested. How are you doing?' 'Not bad, not bad. How are you. What's on your mind for camping? '
Utterance: 'I'm doing well. We're desperately needing wood. We didn't realize how cold it would be as it is our first time here. There is none around our area so we are really concerned about staying warm especially at night. We also forgot a bag of food, so that's another need for us.'
Example Output:
Yes
