I also chose E.This question tests parallelism in comparisons. When you compare two things, say X and Y, X and Y must logically be parallel. So, what entities are being compared? Jobs that can be done
at home vs jobs that can be done
at the office. As pointed by
zhanbo the active voice is better and more direct than the passive voice ceteris paribus. If there are no errors in the sentence, the meaning is the same in the options but some options are in active voice while others are in passive voice, by all means choose the active voice over the passive voice. This is because the option in passive voice will definitely be wordier than that in the active voice.
Quote:
A) Millions of workers have jobs that
are able to be done as well
at home as
at the office, instead of consuming the gasoline used to get to work.
The parallelism is okay in A. X: Jobs that are able to be done
at home vs Y: Jobs that are able to be done
at the office. Actually the comparison is between
at home vs
at the office. Everything is okay except for the wordiness of
are able to be done. Keep A, and look for a better option.
Quote:
B) Millions of workers have jobs that can be done as well
at home as
the office, rather than consume the gasoline they must use to get to work.
There is an error in the parallelism in B.
at home, a prepositional phrase, is not parallel to
the office, a noun. Eliminate B.
Quote:
C) Instead of consuming the gasoline used to get to work, millions of workers have jobs that
are able to be done as well
at home as
at the office.The parallelism is okay in C. X: at home, prepositional phrase and Y: at the office, a prepositional phrase. X and Y are parallel. There is a trick I usually adopt in sentence correction. If two options are basically the same, neither can be correct, hence I will mark them as wrong. Look at A and C. They are indistinguishable. On hindsight, I know both are wrong. But Keep C also, we will find a better reason to eliminate both
Quote:
D) Rather than consume the gasoline used to get to work, millions of workers
can do their jobs as well
at home as
the office.
Once again X: at home, a prepositional phrase is not parallel to Y: the office, a noun phrase. Eliminate D.
Quote:
E) Instead of using gasoline to get to work, millions of workers
could do their jobs as well
at home as
at the office.
The parallelism is correct in E. X: at home, a prepositional phrase is parallel to Y: at the office, a prepositional phrase. Keep E.
Now the difference between A, C, and E is the concision of the verb used. A and C use are able to be done while E uses could do. Obviously could do is more concise than are able to be done. Hence eliminate A and C for wordiness and keep E as the best answer for its more concise verb.
