You will be given a definition of a task first, then some input of the task.
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.

Context: 'You can have most of the water and firewood if I can have most of the food. I would like to get two of the firewood so I have a nice fire to come back to after searching for a source of water.' 'How about I take all off the water, 1 firewood and 1 food package? 🙂' 'You can have all of the water if I can have all of the food. I promise that I will bring you back food. I am really good at foraging and I know all about what is edible in a forest 🙂 I want to have two packages of firewood so that I can have a roaring and hot fire going when I come back from being out all day. I am sure that I will find some fish to catch at my water source! 🙂 I'll bring some to back to share with you!'
Utterance: 'Thank you, I would appreciate that and it is very generous of you, Im not a strong hunter or fisher at all :) '
Output:
No
