This process resulted in a total of 15 new townships: of which, to date, 7 are still in existence.

(A) of which, to date, 7 are still in existence.
(B) of which number, 7 of the 15 are still, to date, in existence.
(C) of the number 15, 7, to date, are still in existence.
(D) to date of these 15, 7 are still in existence.
(E) to date, 7 of the 15 are still in existence.

Explanation says that "of which" in option A and B do not clearly refer to any antecedent.

Experts please explain why "of which" in options A and B is not referring to "15 new townships" ? "of which" is placed adjacent to "15 new townships" in both options A and B.

I am sorry for the mistake. The original source has the comma. Below is the correct question:

(A) of which, to date, 7 are still in existence.
(B) of which number, 7 of the 15 are still, to date, in existence.
(C) of the number 15, 7, to date, are still in existence.
(D) to date of these 15, 7 are still in existence.
(E) to date, 7 of the 15 are still in existence.

Could you why "of which" in options A and B is not referring to "townships"? The original explanation says that "of which" has not clear antecedent.

To me, it looks like the answer should be (A). If the comma were a semi-colon, then (C), (D), or (E) might be up for consideration, but a comma cannot link two clauses without a conjunction. With a comma, only (A) and (B) avoid the trap of being a run-on sentence

Hi sungoal, Can you double-check that this is copied properly from the original source? The GMAT rarely tests the proper use of the colon, and none of the answer choices seem correct following a colon regardless. Should this have had a semi-colon or comma instead? _________________ Eli Meyer Kaplan Teacher http://www.kaptest.com/GMAT Prepare with Kaplan and save$150 on a course!

The question is from GMATClub Test.

I think there is a printing mistake in the question. The answer according to the explanation is E.

So I think, as you said, it should be semicolon in the question.

Could you explain, why without semicolon options C, D and E are run on sentences?

A "clause" is a Noun-Verb pair that conveys a complete idea. In a properly constructed sentence, clauses must be connected to one another; the general rule is that a sentence with N clauses must have (N - 1) connecting words (a semi-colon functions as a connecting word for this purpose.

(C), (D), and (E) all connect the two noun-verb pairs "process resulted" and "7 are" with only a comma, and no connecting word (such as But, Although, or And). Thus, the last three choices all appear to be run-on sentences.

I have a minor doubt regarding the usage of WHICH, other that the discussion above.

Below are 3 sentences, can you please tell me which of the usage(s) is/are correct?

1. I have books, which are red.
2. I have books which are red.
3. I have books, of which 3 are red
4. I have books of which 3 are red.
