Ex Input:
Context: 'Hello 🙂 Hope you have a good amount of supplies for your trip!' 'Not really! I will need you to give me 3 food, 2 water and 2 firewood.' 'Yea, that's not going to work for me. That would leave me with NO food, and only 1 water, and 1 firewood. Would you take that deal, if I offered it back to you?'
Utterance: 'Ok what will work for you?'

Ex Output:
No


Ex Input:
Context: 'Hello! I am a mother of two and I have two kids who need extra food and water' 'Okay, I need food and water too unfortunately. We can discuss this.🙂'
Utterance: 'Alright... my baby is on formula and needs water for her bottles. My son snacks all day and really needs food. Otherwise, he will starve and won't thrive'

Ex Output:
No


Ex Input:
Context: 'You can find more wood in the forest but I'm going somewhere where there's not a loot of trees ☹️' 'That makes sense. What if you took 2 firewood in exchange for 1 additional food?' 'you can have 3 food'
Utterance: 'Alright🙂 From what I understand, that means that you would take 3 firewood, and I would take 3 water and 3 food. Is this your understanding as well?'

Ex Output:

No
