'where' can only refer to a place, hence A & B out.

Of C, D & E, I don't like 'its' in E and C doesn't make logical sense. D could be the answer.

[GmatKiss]

Its not D!

[studentps2011]

Hmm...is it C? Can someone explain?

I am confused b/w A and C. Would go with A as C changes the meaning...
wats the source and OA??

[sungoal]

The answer should be C.

This is the question from 1000 SC, question number 925. The OA in this source is given as A which is wrong.

Thanks for the clarification.
Could you please explain why C is preferred over others!

TIA,
GK

[thestartupguy]

The answer choices narrow down to C n E.

In C, in support of is ambiguous where option E clarifies who is supporting.

so IMO E

what's the OA?

[sungoal]

D is wrong as it saying "members' prejudice". Members can not have one prejudice. It should be "Members' prejudices".

Option E is wrong because of the awkward gerund phrase "supporting of", option C corrects this error by using "support of" .

[smackmartine]

IMO C
I love how the meaning works...
Clearly we are looking for a contrast. where Vs while - while is the winner.
Also, after 1897 ....bla bla.. suggests that an event described earlier must occur before 1897 , so past participle must me used.

(A) Where once the union had acquiesced to the prejudices of its English-speaking members by supporting

Option E is wrong because of the awkward gerund phrase "supporting of", option C corrects this error by using "support of" .

Thanks,

Also in C i see, "in support of" to be a valid idiom. Does this give us an advantage.

Yes...

Of course, in real-life proper Standard English, where does not refer only to place. The GMAT may well prefer to simplify and have greater clarity, of course, but luckily there are the other errors.
