Medium: Firewood
High: Food
value2reason: Low: if the food contains water, that helps keep you hydrated.
Medium: it could be cold, so a fire is important to prevent hypothermia.
High: food gives you energy, which is very important.

Negotiation dialogue:
mturk_agent_2: i really need to keep my energy up, so having a lot of food is important to me.

mturk_agent_1: I understand, is there anything else you need?

mturk_agent_2: I'd like some firewood, too, and maybe a little water.

mturk_agent_1: I guess we are in the same boat.

mturk_agent_2: which items do you need?

mturk_agent_1: Food is most important, I have to cook for the group

mturk_agent_2: What if I give you one of the food and two of the water, and also a firewood?

mturk_agent_1: That's not bad

mturk_agent_2: That way we all get some of everything. 

mturk_agent_1: Well yes but if i am cooking the firewood is more important than the water

mturk_agent_2: What if you take one food, two firewood, and one water?

mturk_agent_1: I guess the food is really important to you?  How about you give me all the firewood and you keep the water

mturk_agent_2: Yes, the food is really important. But I can't cook it without any firewood. So I need at least 1 firewood.

mturk_agent_1: Alright then give me one additional water and i can make pancakes

mturk_agent_2: What if you take 1 food, 1 firewood, and 2 water?
