The compared entities are Accredited and Non Accredited colleges, only A and B follow the parallel structure for comparison. Hence C,D,E are eliminated.

A is parallel and clear compared to B

+1 for A

+1 for A.

(A) nonaccredited colleges, while still able to enroll students and to provide instruction, cannot provide their students with the same types of services --> Correct, maintains parallel construct, removes modifier error, and the sentence is clear and concise

(B) nonaccredited colleges cannot provide their students with the same types of services, though still able to enroll students and provide instruction --> Modifier error

(C) enrolling students and providing instruction, while unable to provide their students with the same types of services, are nonaccredited colleges

(D) the services of nonaccredited colleges, while including the ability to enroll students and provide instruction, do not include the same types of services

(E) those of non accredited colleges include enrolling students and providing instruction, but not the same types of services

Hence, A.

sudarshan22 can you please explain why is in B a modifier error?

Thanks!

Ok, I didn't noticed it...

From MGMAT SC --> A noun and its modifier should touch each other

In this case, the modifier "while... " has to be next to the noun it modifies so thats why B is wrong

In contrast to accredited universities that can grant degrees and whose students can be eligible for federal aid, nonaccredited colleges, while still able to enroll students and to provide instruction, cannot provide their students with the same types of services.


(A) nonaccredited colleges, while still able to enroll students and to provide instruction, cannot provide their students with the same types of services

(B) nonaccredited colleges cannot provide their students with the same types of services, though still able to enroll students and provide instruction

(C) enrolling students and providing instruction, while unable to provide their students with the same types of services, are nonaccredited colleges

(D) the services of nonaccredited colleges, while including the ability to enroll students and provide instruction, do not include the same types of services

(E) those of nonaccredited colleges include enrolling students and providing instruction, but not the same types of services

KAPLAN OFFICIAL EXPLANATION:



This sentence contrasts accredited universities with non-accredited colleges, and recognizing that the correct choice needs to begin by mentioning non-accredited colleges allows you to eliminate choices (C), (D), and (E). (B) is wrong because it misplaces the final modifier; though still able... modifies nonaccredited colleges and therefore needs to be placed directly next to it. That leaves (A), the original sentence.

An 800 test taker knows he must be able to eliminate four of the answer choices for specific and valid reasons before he can safely choose choice (A)—the original sentence.

Please validate if my understanding is correct.

Isn't "though" in option "B" used as a subordinate conjunction. In such a case, a legitimate clause should follow. The part following "though" clearly misses a subject and a verb. It gives us another reason to discard option B.
