Thanks a lot for the reply, Yes thats pretty much what I wanted to to clarify.
Should Barbara Jordan be required immediately after 'Although....,BJ)
If C had 'were' for hearings would it be correct answer or would it still be wrong as it is followed by 'It was not until..' and not 'Barbara Jordan' after comma.

From the posts, I am still confused as few have opinion that
it is required for Barbara Jordan to be followed after first comma(like sam2304 ) and few say its not required( like Essatsnark)

Check the following examples from the OG12:

Q7: As ITS sales of computer products have surpassed those of measuring instruments, THE COMPANY...
Q28: Building on civilizations that preceded THEM in coastal Peru, THE MOHICA...
Q31: Even though many of HER colleagues were convinced that genes were relatively simple and static, BARBARA MCCLINTOCK...

In each case, the introductory modifier includes a pronoun without an antecedent. In each case, the referent BEGINS the clause that immediately follows.

Thus, in the SC posted above, I would be skeptical of A, C, and D. B and E are better, since in each the referent of she (Barbara Jordan) BEGINS the clause that follows the introductory modifier.

this is right on. a couple of extra comments:

this is not really the sort of thing for which you should memorize a rule; instead, just think about the clarity/readability of the sentence. remember, the sentence starts with a pronoun that doesn't stand for anyone yet -- creating a degree of uncertainty as to the exact meaning of that pronoun. in this kind of case, a well-written sentence should resolve that issue by supplying an antecedent as soon as reasonably possible.
so, by comparing the answer choices (NOT by trying to memorize a million rules that will inevitably contradict each other), you can figure this one out pretty quickly.

there's also the issue of the logical cohesion of the whole sentence. in particular, barbara jordan is the subject -- both grammatically and in terms of meaning/focus -- of the first clause. since she is also the topic on which the second clause is focused, she should be the subject of that clause, too.
