TASK 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 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.
PROBLEM: Context: 'HI, my heater hasn't arrived yet and we are in need of extra firewood. Plus, we're camping where there is 6 months of darkness, in Sweden. 😮' 'hi turker i will be needing firewood as well because i need to keep warm while i camp.i suggest i take 2 firewood, 1 water and 1 food while you can have 1 firewood, 2 water and two foods' 'I can take 2 firewoods, you can take all the food and most of the water. So, I am offering you all the food and water.🙂'
Utterance: 'I suggest you look at my offer because you can get hungry and also need water.i really need the firewood as well'

SOLUTION: Yes

PROBLEM: Context: 'What I don't understand is that you requested I respond quicker to your messages, yet you do not respond with much detail or discussion.' 'i want my share as well I give you 2 wood 2 water  and one food ' 'But why should I share with you? You requested that I respond quicker to you yet all I know is that you will be camping with only 1 other person :(. All you plan to be doing is leisurely looking at bird-watching. Will you be really using all of the items? '
Utterance: 'Yes I would and i am willing to share and give you enough wood for your kid, but it gets cold and I would like to stay warm at night i bring some of my food but the lake is most likely not that clean to drink water from. you want to practice fire making once it burns it burns. '

SOLUTION: Yes

PROBLEM: Context: 'Hmm.. well let's see! What is your second priority? I would be willing to give up all of that, if I could get at least 2 firewood. You're right, it sure does get chilly ☹️' 'What if I got 3 foods and 2 waters. and you got 3 firewood and 1 water. If I could get a little more food that doesn't need to be cooked over the fire I might be able to get by. And I'll need to buy more water so I don't have to boil it since I won't have much firewood. ' 'I would say that sounds like a good deal! I am a little worried about water though, there aren't any sources of water where we are going. Hmm..'
Utterance: 'I think having 3 packages of firewood will help! you can always boil water from a  fresh spring 🙂'

SOLUTION:
Yes
