[Q]: Context: 'I will take all the food and water then' 'That will be very unfair of you. How am i going to survive without water or food?' 'You have food and water, this is just extra supplies'
Utterance: 'I know but with my condition i may not make it, especially without more water.😮'
[A]: No


[Q]: Context: 'Hello!  I'm going to be heading out on a big camping trip and will need to take some extra supplies.  Are you going camping as well?'
Utterance: 'I am also going camping! What do you think you're going to need the most of? What are your preferences?'
[A]: Yes


[Q]: Context: 'Me too!  I'm hoping for two food items and one water.  I'm diabetic so if my blood sugar drops, I may need the extra carbs.  And water because water is important! 🙂 ' 'I prefer two water and one food. I can understand why you need the extra food items. I'm not much of a snacker but do drink a lot of water all the time. Keeps me from eating more!🙂' 'Lol, it seems it was easy for us to come to a deal!  I'm super bad at drinking water (trying to get better) so I don't feel I'll need as much.  Do you want all of the firewood or should I take one and you take two?  '
Utterance: 'I don't have a preference on the firewood. You may have two if you like. It's so hot that I don't cherish the idea of a fire BUT it does keep the bugs at bay!🙂'
[A]:
No
