OA  A

kbulse · Answer

for the correct parallelism we need "and of" construction that is why we can eliminate B, C, D
between A and E I chose A because it focuses on a "black hole" not on where it lies,

spriya · Answer

Between E and A ,i marked A !!!
yes E was a strong competitior but as it had a diff meaning !!!lost infront of A

spriya · Answer

center of milky way and of Y 
hence this is met in A !!!

scthakur · Answer

I hate the SC questions that involve logical meaning to get the right answer.

A is right here because of logical meaning and parallelism.

What A essentially says is that black hole lies at the center of milky way and it lies at the center of many other galaxies in the universe.

KASSALMD · Answer

A seems correct because it preserves the context of the question. There is a black hole that lies at the center of the milky way and in the center of each of the other galaxies. Only A is indicative of that fact even though A does not seem grammatically correct. To be correct, the language should have been: " ......and that of millions of galaxies.....".
However, of all the choices, A seems relatively correct.

santosh_surathkal · Answer

I am still confused between A and E ...
Looks like A could be a obvious choice unless and untill we can find a fault in it.

kbulse · Answer

A.   that a black hole   lies at the center of the Milky Way and of
E. of a black hole   that lies at the center   of the Milky Way and of

see the word "that" changes the meaning(focus) of the sentence

seofah · Answer

Initially chose E, but stop at A!
"that..." clause should modify "theory", as it does in A. E is changing the meaning.

GMAT TIGER · Answer

When there is "the theory", "that" should follow it. So A and B remain.

Now between A and B, A is parallel while B is not.

So A should be correct..

ritula · Answer

Thinking words such as belief, theory, believe etc must always be followed by "that". so Dand E are out.to maintain parallelism if the theory was about black hole and many of the glaxies then it would have looked like this:
 that  a black hole lies at the Milky Way’s center and  that 
So B and C are also out. 
In fact here ther theory is abt black hole which exists at the center of milky way and (center) of many of the 100 billion other galaxies. So A is absolutely right.

lylya4 · Answer

I choose E, as for A, "estimated to exist in the universe." is not clear whether to modify the black hole or galaxies

alpha_plus_gamma · Answer

lylya4, as ritula wrote earlier, GMAT follows the following rule, so on GMAT "theory of" is almost always wrong.

reply2spg · Answer

IMO A....the theory should followed by "that" and due to ||ism, I agree with A.

priyankurml · Answer

Thanks for explanation A is clear now.
