Let’s say you are blindfolded and taken into a gravity free spherical room where you lose all sense of direction and then you are presented with two square shaped sheets of metal. In addition, it’s promised that if a person standing outside the spherical room looks at the sheets in their present positions, then he will say that one of them is horizontal (meaning it’s lying down) and the other is vertical (meaning it’s standing up on one of its edges). Next, you are given the permission to take those sheets in your hands and inspect them in whatever way you want. Your task is to somehow decide which one was horizontal and which one was vertical when they were given to you. To help you out, you have been connected on phone to a person who is standing outside the sphere and who can see the two sheets through a small whole. You are allowed to ask him as many questions as you want, but the only problem is that he speaks French. So if you point to a sheet and ask him if it is vertical or horizontal, he will tell you the right answer, but you won’t understand it. Can you still accomplish your task? (I am assuming you do not understand French.)
I just came up with this puzzle a few minutes ago. I want to know if the answer I have in mind is trivial or not.
