Hi mike,

However, I'm saying what if there are two findings.

1. black hole and where it lies
2. 100 billion other galaxies

Dear sannidhya,
I'm happy to respond again. My friend, with all due respect, I must tell you that you are misunderstanding the meaning of this sentence. Meaning trumps grammar. If a student doesn't understand the meaning of the sentence, then it makes it much harder for the student to understand the grammar of the sentence, because grammar depends on meaning, and the GMAT SC is as much about meaning as it is about grammar.

Here is the question again:
Recent findings lend strong support to the theory that a black hole lies at the center of the Milky Way and of many of the 100 billion other galaxies estimated to exist in the universe.
A. that a black hole lies at the center of the Milky Way and of
B. that a black hole lies at the Milky Way’s center and
C. that there is a black hole lying at the Milky Way’s center and
D. of a black hole lying at the Milky Way’s center and
E. of a black hole that lies at the center of the Milky Way and of

This sentence about a scientific theory, and this theory posits two things. The first point, as you correctly surmise, is that a black hole is at the center of our own galaxy, the Milky Way galaxy. The second point is NOT simply the existence of the other galaxies. This theory is NOT about the discovery of other galaxies. The second point is that a black hole exists at the center of each one of the billions of other galaxies. In other words, this is
. . . the theory that that a black hole lies at the center of the Milky Way galaxy and that a black hole also lies at the center of many of the 100 billion other galaxies estimated to exist in the universe.
That is factually what the sentence is saying, but that version is way too wordy. There are far too many words repeated in the parallel structure. We need to omit repeated words. See:
http://magoosh.com/gmat/2013/dropping-c ... -the-gmat/
We can shorten that to:
. . . the theory that a black hole lies at the center of the Milky Way and of the 100 billion other galaxies estimated to exist in the universe.
This is the OA, (A). Notice the repeated preposition "of" marks the parallelism.

Part of concision is dropping common words from the second branch of parallelism. It's always tricky to read a sentence in which these common words already have been dropped and to infer them as part of the meaning, but this is precisely what the GMAT SC asks students to do.

Does all this make sense?
Mike

So the parallelism is fine here, since it’s exactly the same as in (A). So what’s the only real difference between (A) and (E)? It’s that goofy difference between “the theory of a black hole that lies…” and “the theory that a black hole lies…” And the latter makes more sense.

If you picked (E), that’s not terrible. But given the choice, (A) is better.

E says: Theory lies at the center of the Milky Way

GMATNinja, is it possible in real life?

[quote="Economist"]Recent findings lend strong support to the theory that a black hole lies at the center of the Milky Way and of many of the 100 billion other galaxies estimated to exist in the universe.

(A) that a black hole lies at the center of the Milky Way and of

(B) that a black hole lies at the Milky Way's center and

(C) that there is a black hole lying at the Milky Way’s center and

(D) of a black hole lying at the Milky Way's center and

(E) of a black hole that lies at the center of the Milky Way and of

if we see a split between
noun+verb
and
there is+noun+that+verb (or doing=that+verb)
then think about change in meaning focus
there is+noun+that+verb answers the question " weather there is a noun" while noun+verb answers the question " what do the noun do"?

so, meaning is quite different.

The most likely explanation for these observations, the astronomers said, is the presence of a black hole. Other astronomers agreed that the results lent strong support to the theory that a black hole lies at the center of the Milky Way and probably at the center of many of the 100 billion other galaxies estimated to inhabit the universe. By their nature, black holes cannot be seen directly, only inferred by the behavior of surrounding forces, so their existence has yet to be established beyond doubt.

"And" is a parallelism marker. Since there is an 'of' after 'and' , there has to be an 'of' before 'and'.
Only option A has this construction.

So A is the correct answer.

Please give me kudos if you liked my explanation.

Question specifically to GMAT Ninja as the thought process followed mine exactly verbatim.

I know you have said E is not bad either - but does that mean on the exam day E might be the right choice thrown out rather than A? Would you know?

There is this ongoing issue of correct vs incorrect choices being given as answer...

Hello,

What is the role of "that" in ".....that a black hole lies at the center of the Milky Way..."? Is it acting as a connector? If so, shouldn't it be repeated after "and"?
