The three listed behaviors of companies that successfully establish operations abroad are logically parallel; therefore, they should be structurally parallel. In the original sentence, the first activity “protect with consistency their intellectual property” is not structured in parallel fashion to the second and third activities. Also, the phrase
“empower local managers with aggression” suggests that the local managers are being given the quality of aggression, which is not contextually appropriate; “aggression” is better applied to the act of empowering the managers, not to the managers themselves.
(A) This choice is incorrect as it repeats the original sentence.
(B) This choice incorrectly uses the relative pronoun "which." "Which" should be used for noun modifiers, whereas here "which" is incorrectly used to introduce a set of clauses that are integral to the sentence. Also, the second activity “lobby government officials without tiring” is not structured in parallel fashion to the first and third
activities.
(C) This sentence fails to follow an appropriate parallel structure as it lists the three activities of companies that are successful abroad. Also, the phrase “empower aggressive local managers” suggests that the local managers are aggressive which is not contextually appropriate; “aggressive” is better applied to the act of empowering
the managers, not to the managers themselves.
(D) CORRECT. The three logically parallel activities in this sentence are structurally similar and the sentence is clear and concise.
(E) This choice incorrectly begins with the phrase "of which", which suggests that the operations of the company may be established abroad by a third party other than the company itself. Also, the three logically parallel activities are not structured in parallel fashion.
