The new policy not only reduces operating costs but also _______.
Which choice completes the text so that it conforms to the conventions of Standard English?
employee satisfaction is improved
there is improvement in employee satisfaction
improves employee satisfaction
employee satisfaction improves
Correct Answer: C
Choice C is the best answer. This question tests parallel structure with correlative conjunctions.
- Context clues: "Not only...but also" requires parallel elements.
- Meaning: What follows "not only" and "but also" must have the same grammatical form.
- Verify: "not only reduces... but also improves" maintains verb parallelism.
💡 Strategy: With correlative conjunctions (not only...but also, either...or), elements must be parallel.
Choice A is incorrect because it's a passive clause, not matching "reduces." Choice B is incorrect because it's a different clause structure. Choice D is incorrect because the subject changes, breaking parallelism.
