I agree that Choice D is best answer but I guess that in choice d , it should be written compresses rather than compress because star is singular.

Hi Aarushi, the exact structure that the sentence uses is will compress.

So, the sentence is in future (will). In future tense, we always use the plural form, irrespective of whether the subject is singular or plural.

Stars will compress.

Star will compress.


Hello EducationAisle

Thank you for your contribution to this conversation.

Your response to aarushisingla is absolutely correct and quite succinct.

Thank you once again for addressing this doubt.

A star will compress itself into a white dwarf, a neutron star, or a black hole after it passes through a red giant stage, depending on mass.


(A) A star will compress itself into a white dwarf, a neutron star, or a black hole after it passes through a red giant stage, depending on mass.

(B) After passing through a red giant stage, depending on its mass, a star will compress itself into a white dwarf, a neutron star, or a black hole.

(C) After passing through a red giant stage, a star’s mass will determine if it compresses itself into a white dwarf, a neutron star, or a black hole.

(D) Mass determines whether a star, after passing through the red giant stage, will compress itself into a white dwarf, a neutron star, or a black hole.

(E) The mass of a star, after passing through the red giant stage, will determine whether it compresses itself into a white dwarf, a neutron star, or a black hole.


SC43561.01


Official Explanation

Logical predication; Rhetorical construction

The sentence attempts to convey the idea that a star will compress itself into one of three forms after it passes through the red giant stage: a white dwarf, a neutron star, or a black hole. The sentence also indicates that which one of these three forms the star will compress itself into is determined by the star's mass. As worded, these ideas are not clearly and unambiguously conveyed. For example, it is not clear what the modifying phrase depending on mass is supposed to modify. Because of its placement, it appears to modify red giant stage; it should, however, modify star. Given this problem, the sentence fails to convey its intended meaning clearly.

A. As indicated above, this version fails to convey its intended meaning clearly.

B. The referent of the pronoun its is unclear. Given that red giant stage is the only noun before its, the sentence would seem to indicate that red giant stage is the referent, but the meaning would be correct only if its refers to star. Furthermore, the modifying statement depending on its mass appears to modify red giant stage rather than star.

C. The modifying phrase After passing through a red giant stage modifies a star's mass but it should describe the star itself. Given that the mass is not what passes through the red giant stage, this is incorrect.

D. Correct. In this version, it is clear that the sentence is saying that the star itself passes through the red giant stage and that the star will ultimately compress itself into one of the three listed options: white dwarf, neutron star, or black hole.

E. The pronoun it refers to the mass of a star, rather than a star, as intended. Likewise, the star itself passes through the red giant stage, not its mass.

The correct answer is D.


Hi VeritasKarishma, Bunuel, EducationAisle, generis

My queries are related to option B.

Logically, stage does not have the mass. So, from the logic perspective, it is clear that mass is related to the star. According to the official explanation, its apparently refers to red giant stage's because red giant stage appears before the possessive pronoun its. whether it is necessary to have noun before the pronoun in a sentence?

Also, why depending in option B modifies red giant stage and not a star ?

Thank you.

Hi, more specifically, Whether-----------or-------------not is generally a redundant construct.

For example, following would not be correct:

Mass determines whether or not a star, after passing through the red giant stage, will compress itself into a white dwarf.

However here, three possibilities vis-a-vis neutron star are being expressed:

..a star can compress itself into a white dwarf, a neutron star, or a black hole.

It's like this:

GMAT score will determine whether LoneSurvivor will get admit to HBS, LBS, or Wharton.

Can't think of a better way to depict these choices/options.

Hi,

In Option D - "Mass determines whether a star, after passing through the red giant stage, will compress itself into a white dwarf, a neutron star, or a black hole"

I rejected this answer because of "Mass". It was not clear to me whose mass is it? I mean, hypothetically, Mass can also be a name of a person.
Please can someone explain what I am missing?

C and E uses wrong comparison as Mass of a start does not pass through a red giant stage rather the Star passes through.

In A ,depending on mass is situated way far
In B depending on its mass has wrong suggesting red giant stage

Hence D
