PROBLEM: Context: 'I need to stay hydrated because the weather is hot. I am trying to lose weight so I do not need much food.' '😮I see. I have a medical condition that causes my veins to close if I get too cold. I need more firewood to make sure I don't freeze at night.' 'Would two of the firewood be enough?'
Utterance: 'Maybe... I could perhaps do with 2 firewood. But, I would like at least one packet of water.'

SOLUTION: No

PROBLEM: Context: 'Hi! What sort of packages are you looking for today?' 'Hi there! I am looking to have 3 packages of firewood, 2 packages of food, and 1 package of water please. '
Utterance: 'Oh we have similar priorities 🙂I am also interested in getting firewood, because I have a condition that makes me very cold, colder than the average person, so I need to make sure I have enough for the trip. Why do you want food'

SOLUTION: Yes

PROBLEM: Context: 'Hi! I am looking forward to making a deal with you today.' 'Hello, that sounds good. How are you today?' 'I am doing okay but am in need of some supplies. What about you?'
