请教，OG-83中，答案选的B，可以理解。但解释中说：To present these two causes, the sentence employs a formula that requires parallel elements: not just because of x, but because of y, with x and y assuming the same grammatical form. 答案是not just... but also...结构，ETS解释用的是not just... but ...结构。是ETS笔误还是2种结构都可以用？多谢了

half the increase in spending on prescription drugs,
a phenomenon that is explained not just because of
more expensive drugs but by the fact that doctors are
writing many more prescriptions for higher-cost drugs.
(A) a phenomenon that is explained not just because
of more expensive drugs but by the fact that
doctors are writing
