Ran the gamut = to encompass an entire range of something
Previously, we did not give the universal suffrage to women because several reasons: they ranged (ran the gamut ) from canceling out their husband' vote (The husband voted for Republicans and the woman voted for Democratic) to APE (which means to mock the husband's vote, which means the women voted but indeed they did not have a real consciousness of what they did, voting).
Once these reasons were somehow grounded, now they are shabby, inconsistent.
My personal opinion, especially questions from the verbal side, which are NOT official questions, they do not mimic very close the real ETS GRE exam.
They rely heavinly upon weird, fancy, arcane words in the answer choices to make difficult the question but indeed the sentences are NOT very well constructed. They do not have the real appeal of verbal ETS questions.
They are good only to build up your stamina, not more than.
