大全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.

答案是D .看了讨论还是没明白,E错在什么地方?

(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.

problem 1: after (the mass of a star) passing through... is illogical.

problem 2: The mass of a star, ... will determine whether it compresses itself into a white dwarf, a neutron star, or a black hole.

what does "it" refer to?

if 'it' = the mass, the sentence, whether it compresses itself into a white dwarf , is illogical. 'itself' is not correct either.

problem 3: "will" is also debatable.
