'The relationship ' is singular so option C is gone.

D -- is wrong for using colon after 'because'. in a way, colon itself means 'because' or 'namely' so I can eliminate this option based on this redundency.

A -- is akward (this is because ...)

so it is between B and E ... not sure how to eliminate between these two ... but for me E sounds better than B .. but B is shorter and concise??

I still pick E (or may be B?).

please post OA and OE..

I think this one is about concision issue.. E also seems grammartically correct. But semi-colon may imply causal relationship between the 2 sentences already.

As I remember, colon is used for the causal relationship. Is it true for semi-colon also?

Can you post the OE?

Extremly sorry for the late reply, got busy with other things..
here comes the OE,...

It is from manhattangmat's free online cat

It is a word for word explanation from manhattangmat.
The original sentence incorrectly uses a comma to join two independent clauses. As is the case with the two clauses in this sentence (“The relationship…is still unclear” and “this is because some studies show…while others do not”), independent clauses contain a subject and a verb and can stand alone as independent sentences. While semicolons can join two independent clauses, commas cannot. Further, “this is because” is unnecessarily wordy.

(A) This choice is incorrect as it repeats the original sentence.

(B) CORRECT. The semicolon correctly connects two independent clauses. Also, the singular verb “is” agrees in number with the singular subject “relationship.”

(C) The plural verb “are” does not agree in number with the singular subject “relationship.”

(D) While “is” agrees in number with the singular subject “relationship,” the colon is used incorrectly in this choice. Colons must be preceded by independent clauses. Independent clauses contain a subject and a verb and can stand alone as independent sentences. In this case, however, the colon is preceded by “The relationship…is still unclear because,” which is not a clause that can stand alone as an independent sentence.

(E) While the semicolon correctly connects two independent clauses, and while “is” agrees in number with the singular subject “relationship,” “the reason is that” is unnecessarily wordy. The more concise version in answer choice (B) is preferred.

A) Awkward. what is this referring to? the relationship or why its unclear....
B) Correct. Proper use of semicolon and concise.
C) subject-verb error "are" should be "is"
D) incorrect use of colon.
E) Not Concise. Semicolon already indicates to the reader that the immediate following sentence is closely related.

one more for B

Guys, please post the source of the questions. Some people (like me) are trying to avoid gmat prep, or mgmt questions since still didnt take those tests and are saving them for the future.

Thank you

Great explanations.

Had it down to B and C. Gut said B (sounded better), but went with C because of "are".
