The winds that howl across the Great Plains not only blow away valuable topsoil, thereby reducing the potential crop yield of a tract of land, and also damage or destroy
(A) and also damage or destroy
(B) as well as damaging or destroying
(C) but they also cause damage or destroy
(D) but also damage or destroy
(E) but also causing damage or destroying
Hi! According to the OG, Option C is wrong because
1. "they" is not necessary" (agreed)
2. "to" is required after "cause damage" (yup)
3. "cause damage" is not parallel to blow --> can someone explain this please?
Wouldn't cause damage be a present tense verb just as "blow" is? hence, shouldn't they be parallel?
