Definition: 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.

Positive Example 1 -
Input: Context: 'I was hoping to get alot of water as well, would you be ok with me getting two waters and three firewoods if you get all the food and one water?' 'Hmm, that's not favorable for me going by the volume of items left in my arsenal. Water is more of a higher priority than food. So, I would exchange 1 pack of food for an additional water' 'So that way you would get two waters and two foods? Those are my priorities as well but i would be ok with it since that way i would get five items and you would get only four.'
Utterance: 'Those are your priorities?? Then that's not fair for you. Then I take 2 water, 1 firewood and 1 food. This is the lowest I can offer'
Output: No

Positive Example 2 -
Input: Context: 'I am doing okay but am in need of some supplies. What about you?' 'Same here. My kids are really looking forward to this. What is most important to you?' 'Firewood! I need it to cook my food and also to stay warm. What about you?'
Utterance: 'That is the same for me as well. My kids were really looking forward to making s'mores and telling stories by the campfire. That's all they've been talking about'
Output: Yes

Negative Example 1 -
Input: Context: 'Hi! How are you doing today?' 'I'm fine. And yourself?' 'Pretty good. I'm really excited about going camping though!'
Utterance: 'Me too. I haven't been camping for several years. '
Output: Yes

Negative Example 2 -
Input: Context: 'Hi, I hope we can work together to get an offer that benefits both of us.🙂'
Utterance: 'I agree! Nice to meet you... I have two boys who always eat! Any chance I canget 2 food?'
Output: No

Now complete the following example -
Input: Context: '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.' 'True. Turns out i'm dealing with similar situation, we didn't expect weather to be as cold, so extra wood is on my mind as well. Everyone might need to go to bed earlier and cook food that cooks short time since we low on wood !' 'Yes, that's very true. I would be willing to give up water for more firewood.'
Utterance: 'I like that. I could help you out. I'd be interested in giving you some extra food for extra water. We like to go far from campsite to hike and get up to high elevation, so i need to pack extra water just in case. We go during day, when it's warmest and need extra food in case we come back at nigh time or get lost! Not ideal. '
Output: 


Answer: Yes
