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'
