> which is impossible

Or, generally, is only possible in a non-Euclidean geometry (which the Russian students apparently did not know very well).

I doubt knowledge of non-Euclidian geometry expected in standardized tests like SAT or ACT, where supposedly this problem came from.

I think the whole story is a joke (not unlike the one about the "space pencil").
