Hi Ron,
I have gone through the following discussion on this sentence-
can-somebody-help-me-out-with-this-question-t4278.html
i have 2 questions-
1.You mentioned that for demosntrative pronoun that/those etc in diffirent caluses they have to maintain same structure..the reason we eleimnated option A
But here fewer than have been is acting as a modifies seperated by dash rather than a comma(to put more emphasis)..
How can a modifier is in parallel clause without a parallel indicator as but,or,and etc
A modifier need not be paraller to the clause or noun it is modifying
2.Also can you give an example of 2 parallel clause with same structure and one of them using that/those etc
Thanks,
Vijit
