248. By offering lower prices and a menu of personal communications options, such as caller identification and voice mail, the new telecommunications company has not only captured customers from other phone companies but also forced them to offer competitive prices.
(A) has not only captured customers from other phone companies but also forced them
(B) has not only captured customers from other phone companies, but it also forced them
(C) has not only captured customers from other phone companies but also forced these companies
(D) not only has captured customers from other phone companies but also these companies have been forced
(E) not only captured customers from other phone companies, but it also has forced them
C, the best choice, correctly uses the parallel construction has not only x’d but also y’d and avoids ambiguity of reference by using these companies rather than them. In A, B, and E, the referent of the pronoun them is ambiguous; because them appears to be parallel to customers, the illogical suggestion is that the new telecommunications company has forced customers to offer competitive prices.[size=18] Choices B and E may also be faulted for the improper insertion of it to refer redundantly to the new company. Finally, E is not parallel in verb tense with captured... has forced. Choice D does not maintain parallelism, unnecessarily shifting from active (company not only has captured) to passive (but also these companies have been forced).[/size]
OG #125
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 young plants.
(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
Choice D, the best answer, correctly employs the correlative construction not only x but also y, where x and y are grammatically parallel and where both x and y (damage and destroy) apply to young plants. Choices A, (not only... and also), B (not only... as well as), and C (not only... but they also) violate the not only... but also paradigm. Moreover, B contains terms (blow... damaging) that are not parallel. In C and E, damage is used not as a verb with young plants as its direct object but as a noun receiving the action of cause; consequently, these choices fail to state explicitly that the damage is done to young plants. E also violates parallelism (not only blow... but also causing).
