OFFICIAL EXPLANATION:
The underlined portion of this sentence contains a list joined by and, which is a pretty good clue that you should be vigilant for any lack of parallelism. Because the three phrases joined by and are not all constructed the same way, you know there’s an error, so eliminate Choice (A).
Next, eliminate the answers that don’t solve the problem. Choice (C) keeps the same faulty construction as the original statement in the first two recommendations, and it introduces even more awkwardness by changing use to used and adding it to the end of the third recommendation. You can clearly eliminate Choice (C). Get rid of Choice (E) because it’s also worse than the original. Each of the three elements in Choice (E) has a completely different construction.
Both Choice (B) and Choice (D) seem to correct the error by introducing each recommendation with a similar construction, but Choice (D) creates a new error because it changes the meaning of the sentence. If you select Choice (D), you’re stating that some departments are also unneeded and should be eliminated. The original, however, stated that departments should be consolidated. An answer can’t be correct if it changes the meaning of the original sentence, so Choice (D) is wrong.
Choice (B) solves the problem without changing the original meaning, so it’s the one to choose: The consultant recommended that the company eliminate unneeded positions, consolidate existing departments, and outsource when possible.
