question:
Context: 'Hi I am also going camping. Unfortunately I need as much firewood and water as possible too. I need to be able to cook our food and stay warm all night ' 'Can I ask how many people are camping with you? Are you planning on hiking the mountain?' 'Oh yes, I have my whole family coming. I'm really excited because we don't see each other often. My aunts, uncles, cousins. Some of us will hike while others stay back. Maybe we can come to an agreement? Will you also be hiking?'
Utterance: 'Yes hiking for sure.  If I take 2 firewoods and give you 2 waters and 1 food, would that be acceptable?'
answer:
No


question:
Context: 'Do you have any preferences in regards to the firewood, food, and water? I would like us both to get what we need.' 'I get really cold at night so I'd like to have extra firewood. ' 'Same. Plus I am planning on keeping a fire long into the night. Eating alot of food also helps keep you warm while sleeping. Perhaps I could offer you some extra food in return for some extra firewood?'
Utterance: 'Hmm I will have to think about this offer. How do you feel about the water packages?'
answer:
Yes


question:
Context: 'I have managed to bring pouches of some of my favorite seasonings.  I'm hoping to find some great wild mushrooms in the forest too.  ' 'I'm a big fan of well seasoned food and mushrooms! Mmm.. 🙂 Do you think it would also be alright for me to have 2 of the 3 waters since I will be hiking a lot?' 'That would be fine.  I was hoping to have 2 but since I am only walking and you are doing more heavy duty hiking, you take them.  Agreed?'
Utterance: 'I really appreciate that. Do you think you will be okay with just 1 water since you have health issues?'
answer:

No
