PROBLEM: Context: 'I'm well! Excited for this camping trip.' 'Same! I'm a little worried about some of my supplies though. What about you?' 'Likewise! What are you most in need of?'
Utterance: 'Well, I'm camping up on a snowy mountain and I gave some of my food away to hikers who were passing me and were very tired and hungry, so I'd really like to get some more food. Firewood would be useful too, although I do have a thick coat and a sleeping bag. I plan on melting the snow to get water, so I don't think I'll need that too much. And you?'

SOLUTION: Yes

PROBLEM: Context: 'Hey! I'd like some more firewood to keep my doggo warm. What do you need?' 'I need firewood as well. We have a large group consisting of mostly senior citizens, including my grandma, so we'd like the firewood to keep everyone warm.' 'I see. 😮 What are you least interested in?'
Utterance: 'We can make do without extra water. Can we trade two waters for an extra firewood package and an extra food package?'

SOLUTION: No

PROBLEM: Context: 'Hi! How is your camping trip going?' 'It's going good we could use some more supplies such as food and firewood, though.' 'Same here haha. Is water your lowest priority item too?'
Utterance: 'Yes. We think we have enough water for now.'

SOLUTION:
No
