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.

Example Input: Context: 'I agree that we will! I do love having food as well. Have lots of people coming.' 'I'm not as keen on food, so how does this sound.  I get 2 firewood, 2 waters, and 1 food.  You will get 2 food, 1 firewood, and 1 water. ' 'Hmm, you're getting my top item there though. That still might work.'
Utterance: 'I think it's pretty fair since we'll both get at least one of our top item (firewood) and you get more food (I assume your second priority) and I get more water (my second priority)'
Example Output: No

Example Input: Context: 'OK ' 'Thank you very much. I am anemic so it helps to have all the firewood to keep warm.🙂' 'OK NO MENTION AND WHY YOU WANT FOOD'
Utterance: 'I tend to eat more food when I am active outside. I drink more water too because I don't want to get dehydrated.'
Example Output: No

Example Input: Context: 'Hello, what is your preference for supplies?  I would prefer to have as much extra firewood as possible, but am relatively indifferent to the rest.' 'yes we have to supply more how much you want'
Utterance: 'I would like 3 firewood, and 2 food.  You can have 1 food and all of the water.'
Example Output:
No
