KAPLAN OFFICIAL EXPLANATION:
D.
The original sentence uses the passive voice (
it was decided), but the GMAT strongly prefers the active voice, which tends to be less wordy. The last part of the sentence, too, is wordy; it isn't necessary to say that the computers are both
combined and
linked. (B) rearranges the sentence but doesn't correct either problem. (C) addresses the wordiness issue but not the passive voice, while (E) uses the active voice but remains too wordy. Correct choice (D) addresses both of these errors, converting the passive voice
to active and simplifying the last part of the sentence.
