Because of the Sun, which is 400 times larger than the Moon, but also 400 times farther away from Earth, so both the Sun and the Moon have the same apparent size in the sky.

The mystery of this thread can be unraveled by going through the motions of sentence syntax and one of the general roles of coordinated conjunctions in sentence formation.

A. Because of the Sun, which is 400 times larger than the Moon, but also 400 times farther away from Earth, so both the Sun and the Moon have the same apparent size in the sky. ---- This is a simple sentence introduced by the prepositional modifier ‘because of”. Please note a coordinated conjunction such as ‘so’ can connect equal and parallel items on either side of it. Thus one can connect tow ICs but not a modifier and an IC, as done in this case. Wrong


B. The Sun, which is 400 times larger than the Moon, is also 400 times farther away from Earth, so the Sun and the Moon have the same apparent size in the sky. --- This is the kind of conjugation a coordinated conjunction is capable; ignoring the modifying relative clause for the time being, you will find that the connector ‘so’ connects to ICs. Correct choice

C. The Sun and the Moon have the same apparent size in the sky because the Sun, which is 400 times larger than the Moon, and also 400 times farther away from Earth. --- The subordinate clause starting with ‘“because the Sun,” has no tangible verb for the subject the Sun and hence is a fragment. Wrong (This answers what is wrong with C)

D. Four hundred times larger than the Moon and 400 times farther away from Earth, the Sun has the same apparent size in the sky as the Moon's.—The Sun per se is being compared with the moon’s something; may be the intention is to compare the moon’s size but still it is a wrong comparison

E. Four hundred times larger than the Moon and also 400 times farther away from Earth, so the Sun in the sky has the same apparent size as the Moon. --- A coordinated conjunction cannot connect a modifier as done in this case. Wrong

C: Couple of issues:
1. The last and is not matching with anything. The structure seems to be: …because the sun…and also 400 times..!! sun and 400 times clearly have no correlation
2. Perhaps if his last and was to be replaced with is, C might have been an option worth consideration.

D: Phenomenal meaning issue. The original sentence is clearly intended to convey that the reason why the Sun and the Moon have the same apparent size in the sky is because sun is 400 times farther away from Earth. In D, this causal relationship is not coming out at all.

E: Illogically comparing the size of a planetary body (sun) with another planetary body (moon). That is illogical comparison. We can compare size with size; we can compare a planetary body with another planetary body; but we can’t just mix and match.

It's a hidden comparison question. A,B and E are clearly out because of misplacement of modifiers. Now, i between D and B, B wins because in D Moon is in possessive form and the sentence compares the apparent size of Sun with the Moon's size. Incorrect.

Thanks guys much appreciated. I checked the usual GMAT pitfalls of "which" should modify the nearest noun "the sun".In the process totally ignored "Because" which precedes "the sun".

Since I was confused between (B) and (D), I want to clear below query.

B. The Sun, which is 400 times larger than the Moon, is also 400 times farther away from Earth, so the Sun and the Moon have the same apparent size in the sky.
D. Four hundred times larger than the Moon and 400 times farther away from Earth, the Sun has the same apparent size in the sky as the Moon's.

As mentioned by Ashish, option (D) is wrong because it doesn't maintain the causal relationship per the sentence.

As mentioned by OE, option (D) is wrong because the possessive form of moon i.e. Moon's introduces ambiguity.

In my opinion also, option (D) shouldn't be wrong for the ambiguity as mentioned in OE, but it should be wrong as mentioned by Ashish.

So, my query...

Is using possessive form of a noun for comparison always wrong on GMAT?

Just to add on to daagh's explanation.

In the given sentence...

The sun and the moon have the same apparent size in the sky -> Main clause
and the other part is the dependent or subordinate clause.

If the Main clause is followed by a subordinate cluase, we have to use a period, a semicolon or one of the following coordinating conjunction.

For
And
Nor
But
Or
Yet
So

And these coordinating conjunction should be followed by a comma.

Perhaps you meant to say: If the Main clause is followed by another main clause

Perhaps you meant to say: And these coordinating conjunction should be preceded by a comma

HELLO GUYS..

IMO B is correct..

I TOOK 3 MINS TO ANSWER..as per firsrt sentence,if observed carefully,it says

although sun is 400 timer larger than sun,its also 400 times away from the sun and hence they both look the same..

option D is gramatically correct but doesnt appropriately specify this meaning..

option B,though a bit awkward,is gramatically correct as 2 indep. clauses are joined by SO which is among the fanboys and provides the intended meaning..


HOPE IT HELPS :)

My reasoning:
A: Wrong; sentence doesn't make sense when "which...Moon" is removed.
C: Wrong; "also...Earth" is a fragment
E: Wrong; misplaced modifier "Four...Earth"
D: Wrong; Sun should be compared to "Moon" not the "Moon's size"
B: Correct; "so" implies "therefore".
