Question: Context: 'I was hoping for a decent amount of food, just in case my new recipes don't work out, lol. 🙂' 'Haha, makes sense. I'm also interested in food. What if I take 2 waters and 1 food, and you take 1 water and 2 food?' 'I would be okay with that if I could also have all of the firewood. It seems fair since you will be getting the most water. Would that work for you?'
Utterance: 'That seems like a lot to compensate for just 1 water. How about I also get 1 firewood?'

Answer: No


Question: Context: 'Hello! Do you have any sort of preference regarding the 3 camping items?'
Utterance: 'Hello there! It's nice to meet you. Truthfully, I need to get some food and some firewood. What do you need?'

Answer: Yes


Question: Context: 'Hello. I am so looking forward to this camp out. My daughter just called and said she is going to come and bring some of her firiends. 🙂' 'Hello! That sounds pretty reasonable to me. I was going out with a bunch of my buddies. We like to hike a lot in the sun, so we need lots of water. How does it sound if i take all the food and water, but you get all the firewood?'
Utterance: 'I love hiking. My daughter is bringing extra water. So we could trade the water for the firewood. We do need just a little food as I didn't plan on having an extra person.'

Answer:
No
