大全89，do so不会引起歧义？

Although Ms. Bakara had 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.
    

(B) speak on this one occasion since she firmly believed that many minority people, likely most, would have agreed

(D) do so on this one occasion because she firmly believed that many minority people, if not most, would agree

正确答案是D

让我们先把语态和likely most/if not most放一边

Ms.Bakara有两个动作，分别是emphasize和speak，用to do so不会引起歧义？

当然根据句子的意思可以确定do so是speak for Black people，但不考虑句子意思，不会引起do so是代表emphasize还是speak的歧义吗？

she ventured to do so也还是指她emphasized that she could not speak for这件事并不会有歧义啊？？

我有点迷糊

我理解为会有两个意思

1，不说 she emphasize that she could not speak

2，说 she speak on this one occasion
