Participant mturk_agent_2's preferences:
value2issue: Low: Firewood
Medium: Water
High: Food
value2reason: Low: We do not plan on doing much cooking, and if the forecast is correct we will not need a campfire to keep us warm. Consequently, firewood is a low priority for our team. 
Medium: The weather forecast is for relatively hot weather. Our team, hiking through the forest, will most certainly work up a thirst and will need to consume plenty of water. 
High: Our team plans on doing lots of hiking, so we will need plenty of food to sustain us.

mturk_agent_2: What do you need more of? We have food, water, and firewood.

mturk_agent_1: I usually wear extra layers with it goes below 50 degree. Since I hate the cold, more firewood I guess. 😮
