Star compress itself

by jeevan.Gk » Sat Jan 31, 2009 2:11 am
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.

"After passing through a red giant stage, depending on its mass"

This does not make sense. No clear "noun(star)" that is passing through a red giant stage.

Thanks.

in B,
" depending on its mass," modifies red giant stage instead of star..

there is an error of dangling modifier..

@raunekk

Can B be eliminated on base on possessive pronouns ie "its" referring to "star"?

D is the answer

A) .....after "it" passes......
Usage of "it" is ambiguous. Does "it" refers back to what? a star? a white dwarf? a neuron star? a black hole?? uncertain. so A is out.

B) ...."depending on its mass"..... describes "stage" and it does not make sense at all. Illogical.

C) GMAT prefers "whether" to "if"

D) correct

E) ...."it"...... mass? star? ambiguous.

IMO D

In C there is one more prob.
"After passing through a red giant stage, a star’s mass will determine if it "
Here, after passing through a red giant stage, is modifying a star's mass whereas it should modify a star!!
