Input: Context: 'I don't have a problem with you having extra water.  I'll give you all the water, if I can have all of the firewood.' 'I think that's more than fair. That only brings up the food to be divided. One of us is going to have to take less.' 'I'd be fine with taking less food.  So, I would get 3 firewood, 1 food, and 0 water.  Is that correct?'
Utterance: 'And I would get 0 firewood, 2 food and 3 water. That seems right to me.'
