我搜过这一题了，可是貌似木有人问这个问题，希望NN能帮忙回答下 谢谢！

72.Although Ms. Bakarahad previously emphasized that she could not speak for other Black people, she ventured to do so on this one occasion because she firmly believed that many minority people, likely most, would agree with her.
(A) do so on this one occasion because she firmly believed that many minority people, likely most, would agree
(B) speak on this one occasion since she firmly believed that many minority people, likely most, would have agreed
(C) so speak on this one occasion due to her firmly believing that many minority people, even most, would likely agree
(D) do so on this one occasion because she firmly believed that many minority people, if not most, would agree
(E) do so on this one occasion since she firmly believed many minority people, and even most, would likely agree

答案为D，其它问题我都明白，可是这里的do so不会产生歧义吗？虽然从意思上来看很明显地知道do so代替speak for other black people, 但结构上我觉得它既可以代替had previously emphasized 还可以代替speak for other black people甚至可以代替not speak for other black people，这样不就产生歧义了么？有多个动作的时候do so一般到底是代替哪个动作呢？

望解答，谢谢！
