It is used to discover the preference order of the opponent in the negotiation.
question:
Context: 'Would they be okay with 2 food?  Otherwise can give you an extra and I can take either an additional water or firewood 🙂' 'I have a great offer.  How about I take 2 food, 2 firewood and 1 water and you will get the extra water your camp needs!!' 'We place a premium on the water.  That's the same amount of water, do you mean we take 3?'
Utterance: 'I do need some extra water.  So I will need to take 1, but our preference is food and we would need firewood to cook it on.  if you're OK with this, I will submit it.  Its a great deal I think and we'll both get what we need'
answer:
No


question:
Context: 'Well, I am pre-diabetic, so I had to do it for my health. I love food, too...especially sugar!  🙂🙂' 'Oh, that does change things a lot. Diabetes is a hard disease to have to deal with. So you want more firewood than water? And less food than water?' 'Well, I don't know.  I think I would like more water than firewood, but yes less food than water.  I'm a pretty easy going person though! 🙂'
Utterance: 'Ok, let me know what you think and we will go from there. I do prefer more food and firewood than water though.'
answer:
No
