Teacher: 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 uv-part strategy, otherwise output No. uv-part is a selfish negotiation strategy. It is used to undermine the requirements of the opponent. For instance, suggesting that the opponent would not need more firewood since they already have the basic supplies or a suggestion that there might be a store near the campsite where the opponent can get the supplies instead.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Context: 'Well maybe we can work something out between us.  Our food and water was in the bags they loss so I really need those.  Do you think you could make do with 1 food and some water?' 'I really need 2 foods. I can do with 1 water or if you are in a giving mood then maybe I can have 2 waters?' 'Looks like we both really need the food.  If you get 2 food I would need 1 food, 2 water and 3 firewood. '
Utterance: 'Since you will get all the fire would do you think I could have 2 foods and 2 waters. You would get 1 food, 1 water, and 3 firewood. You seem like you are a great outdoor person that I would think you would be able to catch some fish to cook with the firewood.'
Solution: Yes
Reason: Correct. The participant tries to undermine their opponent's needs by mentioning that the opponent can just fish for food.

Now, solve this instance: Context: 'All my girls have brought canteens. I must have enough firewood if they will earn their badge. You can have one, but I won't be able to make due without 2.' 'I could manage with one firewood and two foods, but if you have canteens for everyone, may I then have all three waters? I had planned to collect water from the river, but I'm worried I may get sick.' 'you pointed out that we will need more!  😮 i will take 2 waters'
Utterance: 'I didn't know you had supplied everyone with water before the trip. I was merely trying to look out for your needs, but you said you didn't need them!'
Student:
Yes
