Medium: Firewood
High: Water
value2reason: Low: I have a lot of belly fat, so I have enough fat to burn throughout the day. Food is not on my mind.
Medium: Firewood to keep me warm during the nighttime. It can get pretty cold here at night.
High: Water is essential in our survival. I need as much as possible.

Medium: Water
High: Firewood
value2reason: Low: Although food is important, I am pretty good at hunting and fishing. Plus I can go for a lot longer without food than I can without water.
Medium: Everyone needs water to survive, if there isn't a lake or river nearby, I would need extra water to remain healthy.
High: I would need firewood in order to keep insects and animals away and to stay warm during the night. It is also useful to cook food.

mturk_agent_1: Oh, I see what you did there. No problem I have plenty of firewood for you buddy. 🙂

mturk_agent_2: Great! What extra supplies would you like to bring?

mturk_agent_1: Since it's hot there, I get thirsty and dry real quick. 😡

mturk_agent_2: Oh ok, well I plan on bringing some juice, beer and other drinks. So I could spare some extra water. And I am pretty good at fishing, so I won't need much food either
