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: 'OK NO MENTION AND WHY YOU WANT FOOD' 'I tend to eat more food when I am active outside. I drink more water too because I don't want to get dehydrated.' 'OH OK '
Utterance: 'Do you have reasons for wanting food?'

SOLUTION: Yes

PROBLEM: Context: 'I need at least one ration of food.  Would it be ok with me:  3 firewood and 1 each of food and water.  If you are ok with that, I am too.' 'Sure, that sounds like a nice deal.' 'That's awesome.  Sounds like we need to set the deal up.'
Utterance: 'Agree, I think after I send this message it will unlock, for me to have 2 water, 2 food and 0 firewood.  Thanks for working together'

SOLUTION: No

PROBLEM: Context: 'I am fine with you having the 3 foods. Is it okay if I have 3 water units We are fasting and need lots of hydration.' 'Are you sure you need all of the water? It would be nice to have some extra.' 'Well, we do need the water pretty badly. But I guess wanting all the water is stingy so I will pack extra water since we are not packing food. How about you guys receive 1 water and 3 food units?'
Utterance: 'If you feel you absolutely need the 3 waters, I will let you have them provided I can have 2 firewoods along with the 3 foods.'

SOLUTION:
No
