A has Verb+ing modifier error. "finishing" modifies US instead the "students".

To cross check, try remove the prepositional phrase "i n the United States ", now finishing modifies to students.

E: {relative pronoun & parallelism & idiom, parallelism }

{who, & finished high school or earned equivalency diplomas & from ..to, in 1999 and in 1998. }

All things are rightly and properly used.

1. NOUN + Verbing:
The verbing without comma modifies the NOUN immediately before the verbing.

Example
I know the boy working in the factory.

This sentence has two meaning:
1. I know the boy who is working in the factory.
2. I know the boy while I was working in the factory.
This kills A, B , and C

2. Either X or Y-X and Y MUST be grammatically parallel.
This kills D.

Answer is E.

I was able to get down to E as other seems bad...
runner up was D
but that was not reason i crossed D....infact it seems to follow either x or Y pattern to distract things...

Problems were
either finished high school or they earned an equivalency ......use of they which adds ambuity
and increasing in the last three years of the decade, rose to
increasing and rose give same meaning ...dont need both
so easy kill eventually..

GMAT score is equally counted as your GPA and 78 clicks can change you life.

Whatever is the reason if you remove the either finished high school or from D you can clearly see the redundancy who they thus X and Y are not parallel
