Two men are laying dead beside a cabin in the side of a mountain.
How did they die?
In agreement with Levik here because to arrive at the intended (right) answer requires more information, which for these problems usually comes from feedback from the problem giver in the form of yes/no answers to the questions. While this would be possible on this site, it would be so slow a process (even assuming that Jennifer stuck around to answer them all) that it is prohibitive here. These puzzles are pretty good around a campfire though. My success rate is about 25% on new problems.My guess for this problem is they forgat their key and so froze to death
