sentence correction on mcgraw cd

[wawatan]

The new operating system designed by MegaTech for the Belmont library will not only meet the needs of the library, but it also has the flexibility and power to manage larger institutional databases.

A. but it also has the flexibility and power to manage
B. but it also has the flexibility and power of managing
C. but also have the flexibility and power to manage
D. and also the flexibility and power of managing
E. and it also has such flexibility and power that it can manage

OA is C. this question came out of McGraw cd.
I’m confused b/c isn’t operating system singular so you need “has” vs “have”

I’m thinking that the “it” is ambiguous b/c it could refer to operating system or library. So you could eliminate a and b.

Any ideas, guys?

Hi,

We need the "have" because the verb is actually "will have" - a future tense verb (which incidentally works with either singular or plural).

"The system will have..."

Hope this helps!

easy way to figure out look for the idiom in this question...not only ....but also


c is the only choice which shows not only....but also.

A. but it also has the flexibility and power to manage
B. but it also has the flexibility and power of managing
C. but also have the flexibility and power to manage
D. and also the flexibility and power of managing
E. and it also has such flexibility and power that it can manage

No...i not saying but also is wrong infact it is the easy way to find the problem. prefer the choice in which but also are together.

In A, b but it also is not correct idiom and d, e is out of scope so 'C' is the best answer.
