GMAT Prep Star question

by iamcste » Sun Apr 04, 2010 10:58 am
Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its core, it expands into a red giant, eventually ejecting its outer envelope of gases to become a white dwarf.

(A) Same
(B) Like any star of similar mass, once the hydrgogen in the Sun's core is exhausted, then it expands into a red giant and eventually ejects
(C) As in the case of any star of similar mass, once the hydrogen in the Sun's core is exhausted, it will expand into a red giant, and eventually ejecting
(D) As any star of similar mass would, once the hydrogen in the Sun's core is exhausted it will expand into a red giant and will eventually eject
(E) As would be the case with any star of similar mass, once the Sun exhausts the hydrogen in its core, it will expand into a red giant and eventually eject

[spoiler]Between options D and E which is more correct from parallelism perspective and why?

will expand into a red giant and will eventually eject OR will expand into a red giant and eventually eject

for those who are interested to solve this question, OA =E[/spoiler]

Good one!

construction : modifier, modified part

For D :

Modifier compares stars, so the modified part should start with the Sun itself. But, it does not. The modified part tells about the happening in Sun's core.


For E:

modifier compares cases. Hence, per rule the modified part should be a case.

Yes, in E, it is. The case is "once the Sun exhausts the Hydrogen in its core"

Hence, E follows the rule.

D is totally incorrect in the meaning which it is conveying. The sentence wants to say that it is Sun which will expand into a red giant and eventually eject. Whereas, D says that Sun's core will expand into a red giant.

As far as ||ism is concerned, E again is better.

Rather than using this construction : will X and will Y (X and Y being two verbs)

it is more concise to have will X and Y. Will applies to both the verbs : X and Y.

additional questions

1. If A were "Like any star of similar mass, the Sun exhausts the hydrogen in its core, it expands into a red giant, eventually ejecting its outer envelope of gases to become a white dwarf" would it be right?

2. what signals/indicators in the question does prompt us to use a future tense -"will" in correct statement E..

is it word "once" or "eventually" or not underlined expressions of the sentence "to become a X"?
