Yes

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.'
No

Context: 'Ok, would you do 1 firewood, 2 water and 1 food then?' 'Can I get 3 water and 1 firewood instead?' 'so I get 2 firewood, and 3 food? Ok I will agree to that'
Utterance: 'Great! Sounds like a deal! we have enough food for tonight so I think we will be good. '

No
