Sentence AnalysisComputers are relying increasingly on networked computers for several critical tasks. In these tasks, standard business transactions are handled ‘via computer’ rather than ‘on paper’. VIA COMPUTER is a prepositional phrase and ON PAPER is also a prepositional phrase. Thus, perfect parallelism.
As explained above, the sentence, as is, is clear in meaning, and it also has the parallel structure ‘via computer’ and ‘on paper’. Therefore, the original sentence has no errors.
Also, this SC question
is classic example of the mechanisms used by GMAC for the change of meaning by changing the voice of the sentence. Lets see how??
1.
in which standard business transactions are handled via computer rather than on paper The original underlined sentence is in PASSIVE VOICE and we are not aware of the doer of the action (ACTION -- handling of standard business transactions). But the intended meaning is clear. In these tasks, standard business transactions are handled ‘via computer’ rather than ‘on paper’. Perfect.
VERSUS
2.
in which computers handle standard business transactions instead of on paper Here the voice is changed to ACTIVE and now we are told that the COMPUTERS are the doer. As can be seen that the meaning now implied by this active voice sentence is completely NON-SENSICAL. Therefore, incorrect.
Option Analysis(A) Correct.
(B) Incorrect. For the following reasons:
--
“where”, on GMAT, refers to only physical locations. Therefore, ‘where’ cannot refer to ‘tasks’ here.
-- We have ‘on paper’ after “rather than”. However, ‘on paper’ is not parallel to anything before “rather than”. The only thing it can be parallel to is “where”. However, that interpretation will lead to an illogical meaning that computers handle transactions in critical tasks rather than on paper!
(C) Incorrect. It has Error no. 2 of option B.
(D) Incorrect. For the following reasons:
-- Error no. 1 of option B
-- Enclosing ‘not with paper’ in double commas indicate that it is non-essential part of the sentence. However, in its absence, ‘but instead via computer’ will not make any sense.
TIP : -- whenever you have a NON-ESSENTIAL modifier separated by double commas in between, try to eliminate that non-essential modifier and check whether the remaining sentence still makes sense. If not, then the construction is wrong.(E) Incorrect.
‘in place of’ is a preposition and therefore must be followed by a noun and never by another prepositional phrase “on paper”.
ALso, notice that in the choice E,
the usage of BEING is correct.E. in which standard business transactions
are being handled via computer, in place of on paper
