标题: [求助]补充250-35

35. 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.（D）

(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.

我选了B，我觉得D中，mass做主语，而原句中mass是壮语成分，改变了句子重心。B中，a star 是After passing through a red giant stage 的逻辑主语，depending on its mass 中的its 无论向前还是向后指代，都是a star ，并不会引起混淆。为什么错了呢？

请多指教

Choice A is ambiguous because the grammatical function of depending on mass is uncertain: the phrase could modify either the whole preceding statement or only the words after it passes through a red giant stage. In the latter case, choice A states in effect that a star depends on its mass as it passes through this phase, not the fate of the star depends on the star’s mass. Choice B suffers from the same ambiguity.
