There are no 5 loops, or loops in general. Linq is a bunch of enumerators that may accept some things piped in and yields some results one by one. So even if you insist on claiming there are "loops", there's only 1 of them.

But watch out for the classic rookie fallacy - assuming that having one loop where you do five things per iteration is innately superior to having five loops where you do one thing per iteration.
