Hi Imyuva, the correct answer should be “ by x, y or z” or “by x, by y or by z”
Both are correct: In the first case, "by" is outside the parallel structure (hence used once and covers all the three elements), in the latter inside (hencerepeated).
According to my knowledge as per E-GMAT, either..or is a dual-word marker .. here in the question the list comprises of 3 elements.
Is my doubt valid?
