You're hypothesizing an additional axis of question variation, "Romance-Germanic", in addition to the well-known axis "difficulty". Do we have any reason other than this anecdote to believe this other axis actually exists for GRE? Why wouldn't easy Romance questions be sorted in with easy Germanic questions?

One reason to believe it (or more specifically, to believe the correlation between the Romance-Germanic axis and the difficulty axis is not zero) is that easier / more common vocabulary is often Germanic and harder / more literary vocabulary is often Romance, as a result of the origins of social classes and an intentional desire to use Romance words (or straight-up import Latin words) among those of higher learning / standing. That's the claim of several comments in this thread.
