Example Input: Context: 'Hi, 🙂 can we make a deal for me having 3 water, 2 food, and 2 firewood?' 'no what about this, I get 3 firewood then rest is yours'
Utterance: 'I think can highly consider it, why do you prefer the firewood? '
Example Output: Yes

Example Input: Context: 'okay that sounds like a better deal then! I will take all the firewood and 1 food, and you can take the 2 food packages' 'Awesome, I appreciate that. How does the water need look on your side?' 'I think having two waters would be good for me because my mom forget to pick extras up at the store yesterday😮'
Utterance: 'Oh no! Moms can always be so forgetful. I do notice that leaves you with 6 items and me with 3 though. I think it might be better if I take the 2 waters to make it more equal.'
Example Output: No

Example Input: Context: 'Sounds good, I need food the most, what is your most needed item?' 'my item is food too.' 'Ok, other than food I could use some firewood. Maybe you could take 2 food and I could take 2 firewood?'
Utterance: 'sure, but i will get what then?'
Example Output:
No
