OFFICIAL EXPLANATION
THE PROMPT
A report from the security firm Symantec suggests that in comparison to 2014, the number of fake technical support scams reported rose by 200% in 2015.
THE OPTIONS
• same problem as that in A: the year 2014 is compared to the number of fake scams that were reported
• no reason exists to use past perfect (HAD + past participle risen) (had + verbED)
• use of past perfect requires the presence of at least one event in simple past tense or a time marker that achieves the same result
-- no such simple past tense event exists
-- The sentence uses ellipsis and means: There were 200% more fake reports in 2015 than there were in 2014.
• "There were" and "it is" are called "expletive" constructions.
-- Often these expletive constructions make the sentence longer than necessary. Be on guard.
-- at the same time, when we want to emphasize something (such as the fact that scam reports rose by 200%), we use this "there were" construction.
The emphasis in English is usually at the end of the sentence.
• the verb at the end, was, makes absolutely no sense
• the comparison is not parallel. Now the expletive structure makes a mess.
-- Essentially and incorrectly, this option says: There were more Xs in 2015 than 2014 had.
-- there were Xs and "year had" are not parallel
-- Corrected: there were 200% more fake reports in 2015 than there were in 2014
The answer is C

B) as compared to 2014, the number of fake technical support scams reported had risen by 200% in 2015
• as compared to is commonly used in speech and is very suspect on the GMAT. I would not eliminate on that basis alone, but I would flag the issue• same problem as that in A: the year 2014 is compared to the number of fake scams that were reported

Quote:
C) there were 200% more reports of fake technical support scams in 2015 than in 2014
• the two things correctly compared are "[reports] in 2015 and "[reports] in 2014. -- The sentence uses ellipsis and means: There were 200% more fake reports in 2015 than there were in 2014.
• "There were" and "it is" are called "expletive" constructions.

Quote:
E) there have been 200% more reports of fake technical support scams in 2015 than 2014 had
• no need for have been. Not a deal breaker, but not as good as the language in C• the comparison is not parallel. Now the expletive structure makes a mess.
-- Essentially and incorrectly, this option says: There were more Xs in 2015 than 2014 had.
-- there were Xs and "year had" are not parallel

I chose C. I could not tell anything wrong with C. The comparison between "in 2015" and "in 2014" is parallel.
In (A), the number is compared with 2014. That is not apples-to-apples comparison.
In (B), the issue from (A) persists.
In (D), there is simply no way to expand "than 2014 was" to be a meaningful sentence. In C, we can expand "than in 2014" to be than there were reports in 2014".
In (E), the issue from (D) persists.
