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 elicit-pref strategy, otherwise output No. elicit-pref is a cooperative negotiation strategy. It is used to discover the preference order of the opponent in the negotiation.
PROBLEM: Context: 'Seeing as we both have a medical-necessity for the firewood, it's rather unfair that either one of us take ALL of the firewood. I felt that I was being rather generous with my previous offer.' 'you are right we both need the wood, how about i give 1 wood, all of my water and 2 food and you give 2 wood and 1 food?' 'Where are you camping? Perhaps we can compromise by having our tents nearby each other, which would be like we each get three firewood? I am not willing to trade my package of marshmallows, though.'
Utterance: 'i hope we can come to a compromise 🙂, what is another priority of yours besides the wood?'

SOLUTION: Yes

PROBLEM: Context: 'Okay! You can have all the water. I want all the food.' 'yeah sure, I will share with you all the food. What is about firewood?' 'You can have two if I can have one if you're okay with that.'

SOLUTION: No

PROBLEM: Context: 'i have some spare cans but i am not too worried about it.  its a low prioirty for me ' 'How about your water?  Won't you be going through a lot of water where you are going?' 'i am good on that,  i dont think i will be but its second on my to do list'
