（对注释不解。请帮忙。谢谢。）大全31补充35

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

大全注解中说“Choices C and E illogically maintain that the star’s mass, not star itself, passes through the red giant stage to assume another form.”

想请问：C.E中。主语相同。after的位置相同。为什么一个存在歧义。一个不存在呢？谢谢。

对对对了。忽略了放在从句里了。lsMM 真棒O(∩_∩)O~

看到插入语。我直接当括号省略。默认成整个句子的主语了。

谢谢MM。总是那么耐心回答我的问题。
