没有答案的一道题，求教 GWD 12-19

前人给的答案是C，但是觉得这题应该选e才对。C的it指代不清。e德对应关系很清楚。请大家讨论。谢谢。

Q19:

Heavy commitment by an executive to a course of action, especially if it has worked well in the past, makes it likely to miss signs of incipient trouble or misinterpret them when they do appear.

5. Being heavily committed to a course of action, especially one that has worked well in the past, is likely to make an executive miss signs of incipient trouble or misinterpret them when they do appear.

到底是c 还是e?

B 改变了句子的意思,原来是make...likely to miss o misinterpret..., B改成了make missing signs or misinterpreting ones likely....把动词改成了名词. 我觉得答案都是错的.

C里面的it不知道是什么, 难道指executive?

B~
