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: 'I would need additional food to sustain my energy for my hikes. Do you mind if I take two packages of the food? What are your thoughts? ' 'That sounds good to me.' 'Do you want any of the firewood? Would you be okay if I got two packages of the firewood? '
Utterance: 'It's been pretty cold at night.  Do you think you would be able to carry the two packages of firewood?'

SOLUTION: Yes

PROBLEM: Context: 'Oh no, that's not good.  I still have some left over, but we're running out of firewood to use to heat it.' 'Seems like we are in the same boat, the bear tore our tent to shreds so we are sleeping outside and it is cold☹️' 'Sounds like a rough camping trip.  It has been pretty cold lately.'
Utterance: 'Is it possible I could have 3 food since I have none and 2 Firewood to stay warm and you can have 1 Firewood and 3 Water?'

SOLUTION: No

PROBLEM: Context: 'Great! What extra supplies would you like to bring?' 'Since it's hot there, I get thirsty and dry real quick. 😡' 'Oh ok, well I plan on bringing some juice, beer and other drinks. So I could spare some extra water. And I am pretty good at fishing, so I won't need much food either'
Utterance: 'How nice of you. I certain we can work something out. 🙂'

SOLUTION:
No
