Participant mturk_agent_2's preferences:
value2issue: Low: Water
Medium: Food
High: Firewood
value2reason: Low: If I have to, I'll look for running streams and rivers to get additional fresh water.
Medium: I have some, but don't want to run out, or have mine taken by a wild animal, so I thought a few spares would help as I can put them in several different places for safe keeping. 
High: I need plenty of it so I have the ability to not only cook, but also keep warm

mturk_agent_2: How do you want to divide the water? Do you need any, or can I have all 3?

mturk_agent_1: What will you give me for 3 water?

mturk_agent_2: I'm already giving you most of the firewood, which we both need, but you said you wanted it the most. 

mturk_agent_1: 2 firewood for 3 water?

mturk_agent_2: You'll give me 2 firewood, 3 food, and no water? I'm fine with that
