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: 'It's good, thank you 🙂 Which package is the most important for you to have on your trip do you think?' 'That would be firewood. Even though is really hot there, it gets cold at night. How's the weather for you? 🙂' 'Ah yes, you'll definitely need some extra wood then! It's also pretty cold here, especially during the night. But I would definitely be willing to let you take 2 firewood in exchange for 3 food. We have a lot of people going and will be out in the middle of nowhere.'
Utterance: 'We can definitely work something out. I'll be sure it'll benefit you more than me. 🙂'

SOLUTION: No

PROBLEM: Context: 'hello'
Utterance: 'Hello, what would you like for the packages?'

SOLUTION: Yes

PROBLEM: Context: 'well then give me 1 firewood 2 food and 2 water?, then you have 2 firewood so your boy can practice' '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 '
Utterance: '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? '

SOLUTION:
No
