Sir/Ma'am,
Can you please help me with this question? Because my understanding was that Although requires a subject+verb which I could see only in A. Could you please explain me the fault while decoding this question?
Well Verbal in GMAT is more of reasoning than just using grammar rules, we will go by meaning+some rules to justify answer.
Polio, although it is eradicated in the United States, it continues elsewhere and is able to be brought into the country by visitors.
(A) Polio, although it is eradicated in the United States, it continues elsewhere and is able to be (Here if you see Polio the subject is written alone which has to be parallel to both - although it is eradicated.........states. and - it continues......visitors.
When we put Polio in front of each clause. 1) Polio, although it is eradicated.........states. and - 2) Polio, it continues......visitors.
You will find the ambiguity in the meaning the author intention is not clearly stated if we write it like this. So A can't be the answer. Plus although..... States clause is acting like a non essential modifier which is not the case. So it can't be correct.
(B) Polio, although eradicated in the United States, it still continues elsewhere and can be(Similar to A, Eliminate it)
(C) Although still continuing elsewhere, polio has been eradicated in the United States and could be(Although still continuing elsewhere is a non essential modifier here due to it being separated by comma from rest sentence, while it's necessary to confide the whole meaning the author intends to state (Incorrect)
(D) Although having been eradicated in the United States, polio still continues elsewhere and is capable of being (still continues elsewhere and is capable of are put into parallelism, which can be written as - polio still continues elsewhere , Polio is capable of being brought into the country by visitors.. Wait. Polio is capable of being brought? No sense it makes (Incorrect)
(E) Although eradicated in the United States, polio continues elsewhere and could be(this corrects parallelism issue Polio continues elsewhere , polio could be brought into the country by visitors. Yes Polio could be brought by others, it's not capable itself) (Correct).
Answering to your question, although is a conjunction which is used to connect clauses or sentences, but the use of although in A option is unambiguous, we have to find the meaning behind the sentence which author intends to express irrespective of it dejecting grammar rules. The answer has to be best to the reasoning not to the grammar.
