(See **/ALL CAPS added to the quoted section.) So the first part of this is correct, and I'm convinced this is the only way to determine who's who, but you only have about a 17-22% chance of asking the Random (or Variable) Answerer AND getting the answers you need from that person. (Not sure I have the percentages right, but it's that ballpark.) When I'm presented with a logic puzzle, I've always assumed it could be solved, but I think maybe this one has an additional layer: You have to determine whether there is a way to solve it A. everytime; B. just sometimes or C. never. This puzzle falls under B (I'm pretty sure). So it is a good epistemological lesson: 1. It is possible to determine truth, but 2. it is sometimes by chance and 3. you can increase your odds of getting to the truth by asking the right questions, but 4. sometimes we don't (or can't) have enough information to determine something with certainty. Unfortunately, #4 is often overlooked, even in the field of science.
