IMO E. 
First comma should be followed with "which". The second comma in D makes the sentence clumsy. Stretch from X to Y seems more concise that Stretch.. starting from X to Y . Starting is redundant here i guess.

OA plz

getgyan · Answer

Option D. "Starting from" should also have an "ending at" which is missing in this sentence OA is E :-D

I understand E is clearly the best option. But isn't E also a run on sentence?

KyleWiddison · Answer

The definition of a run-on sentence is a sentence that has two or more independent clauses that aren't properly connected. Independent clauses can stand alone as separate sentences. In this sentence, you have an introductory Dependent clause (Among the...so far,) followed by an Independent clause (nothing...structures,) followed by another Dependent clause (which...Grus). Since there is only a single Independent clause this cannot be a run-on sentence.

I will admit that the sentence is awkward from a meaning standpoint. In E, the core of the sentence is only "Nothing resembles the bubble-shaped structures". "Which" is a non-essential modifier, meaning that we can leave it out of the sentence without really impacting the meaning. "That", on the other hand, is an essential modifier and needs to be part of the sentence for the sentence to make sense. I would argue that you would probably be better off with "that" instead of "which" for the final clause in this sentence, but obviously there are no valid choices using "that".

Hi KyleWiddison

why not B is correct??

KyleWiddison · Answer

Yes, good question here. B is very similar to E and is a tempting answer. It has an idiom problem though. We wouldn't say 'greater than half' in this setup - we need to say 'more than half'.

Thanx a lot....
Overlooked...wht a terrible mistake

Paris75 · Answer

Made a mistake, in D you need something else to complete the " strating at "

Therefore leading only E!

Thx for your posts!

jlgdr · Answer

Hi KW, (or anyone)

One question, is the comma before the underlined phrase enough to get rid of 'that' and instead opt for 'which', which always needs a comma before as opposed to 'that'?

Please let us know

Thanks!
Cheers

Hello,
As long as  that  is used as a relative pronoun clause, it   need not   be followed by a comma (atleast on the GMAT), but if  that  is used as a conjunction, it can be followed by a comma. Anyway, here we see that   that   is used as a relative pronoun introducing restrictive information.

smashbiker84 · Answer

E distorts meaning..without the comma after ..visible sky, the end phrase becomes part of main sentence giving the implication that more than half of the part of visible sky from Virgo to Grus is the part that is affected

Praveengeol · Answer

Kyle, I chose D because FROM X TO Y made sense to me. Can you claridy my doubt. I recognised E as potential answer but let it because of missing comma.

mvictor · Answer

undoubtedly E.

we do not need a comma before that. A and B are eliminated right away.
C - which stretches - singular verb for the plural noun structures - incorrect. - out.
between D and E - ing modifier needs to associate with the noun and verb of the preceded clause. nothing resembles the BSS, starting from X to Y...incorrect usage of ing modifier.
E is better formulated, as now the range associates with the verb "stretch".

E is the answer.

ShreyaMenon · Answer

I dont understand why D is wrong ?
What does it mean that at is missing ?
