Participant mturk_agent_2's preferences:
value2issue: Low: Food
Medium: Firewood
High: Water
value2reason: Low: If I have enough water, I can cut back on food and I get to lose weight in the process.  A win-win.
Medium: Firewood is a perk to keep warm but I could survive without it.
High: Water is the basis of human life, without it and a lot of it, I cannot survive.
