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.

don't understand the reason why D is the answer

A - says that red giant stage is dependent on mass

B - says that it depends on "red giant stage's" mass if a star will become a bh,dwarf or neutron star. Misplaced modifier.

C - Says that "a star's mass" goes trough a red giant stage, not the star.

D - Correct.

E - same as C. The mass of a star passes trough a red giant stage, not the star.

Zipper great explanation! What do you think about the pronouns in these options. How do you think we can use the way IT is used each option to eliminate the wrong options.

Thanks!

This is how I would eliminate based on the pronoun It

A - ruled out as there is no pronoun to qualify the noun 'mass' or the subject 'star'.
B - "depending on its mass, a star will compress" - this is wrong, the noun should be the antecedent to the pronoun
C - Same reason as B
D - Correct
E - Even though the pronoun 'it' is used properly - it is used for the wrong subject "mass of the star".
