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: '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)'
Output:
No
