It comes up from time to time in Algebraic Number Theory and/or Galois Theory,

Aha. I haven't done either of those.

but mainly I think it's there as a good question to test whether a student really understands what's going on.

Well, that was my main guess. Though of course since these questions turned up all the time, they, too, became mechanical. .
