31. 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.

I was thinking about B. What is the OA?

The OA is D. Can someone explain ?

B for me too

(A) "depending on mass" at the end is dangling
(B) Correct
(C) sounds like the mass is going through a red giant stage, not the star
(D) whether is incorrect here - whether a star changes or not would make sense
(E) again, sounds like the the mass is passing through the red giant stage

Whether or not is an incorrect usage. I have read that somewhere. So , your explanation for D does not hold good. Sorry !

picked D.

'depending on mass' is ambiguous in A. In order to be precise, we need to specify that its the mass of the star that we are talking about.

'it' refers to 'star's mass' in C. It should refer to star.

The mass does not pass through red giant stage; the star does. Eliminate E.

Though I cannot pinpoint the error in B (I think it is that 'star' does not immediately follow the modifier), between B & D, D is clearly more precise.

(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.
- what does it stand for, there are so many nouns in front of it
(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.
- 2 subordinate clause back to back without the real subject in them. So its again dangles
(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.
- star's mass passes through the red giant stage
(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.
- same as 'C' mass passes through the red giant stage

May be I have understood the point here. its has no clear antecedent in B.

but in B, "its" can refer to "a star." I really can't see what's wrong with B. Can anyone explain?

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.

a red giant stage - is a noun
its - can refer to this as well. and need not refere only the star
