SC question requires explanation

Sun Dec 30, 2007 1:51 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. Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its core, it expands into a red gian, eventually ejecting
b. Like any star of similar mass, once the hydrogen in the Sun's core is exhausted, then it expands into a red giant and evenually ejects
c. As in the case of any start 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 start of similar mass, once the Sun exhausts the hydrogen in its core, it will expand into a red giant and eventually eject

I will post the OA in a day. Need explanation/reasoning for the correct answer.

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.

There are some errors in the OS

1) Like is used to compare two nouns & as is used to compare two clauses.

2) Present Perfect is used which indicates that the sun started to exhaust its hydrogen in the past & is still doing so, this distorts the logical meaning

b. Like any star of similar mass, once the hydrogen in the Sun's core is exhausted, then it expands into a red giant and evenually ejects

Misplaced Modifier
c. As in the case of any start of similar mass, once the hydrogen in the Sun's core is exhausted, it will expand into a red giant, and eventually ejecting

Misplaced Modifier
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

Misplaced Modifier

e. As would be the case with any start of similar mass, once the Sun exhausts the hydrogen in its core, it will expand into a red giant and eventually eject

All parameters correct.

E

the modifier "while leaving the bank" should be on bill ..not on bill's purse...

check for "Possessive poison" in manhatten GMAT Sentance correction book.

Deeps, "while leaving the bank" is supposed to refer to Arun, but the way it is currently written refers to Arun's purse. The way to correct this is usually to add language to the phrase to clarify, i.e., "while HE WAS leaving the bank".

Option A.
illogical use of the verb 'has;.......'has exhausted' gives the sentence a different meaning.thus, this option is incorrect.

Option B.
'one the hydrogen in the sun's core is exhausted'? The modifier to exhausted here is improper, thus the option has defected. This option is incorrect.

Option C.
Option c suffers same fate as option B. Thus, it is not correct

Option D.
The use of present perfect tense makes this option incorrect i.e the use of'exhausted' instead of 'exhausts'

Option E.
This is the correct option as it properly satisfies the use of tenses and words are connected in a simple well placed modifier.
