GWD9-19 (CD22 7-19) -- 有被省略的部分？？

GWD-9-Q19:

In many nations, criminal law does not apply to corporations, but in the United Stated today, a corporation commits a crime whenever one of its employees commits a crime, if the employee acted within the scope of his or her authority and if the corporation benefited as a result.

1. a corporation commits a crime whenever one of its employees commits a crime, if the employee acted

2. a corporation is committing a crime whenever one of its employees committed a crime, if those employees were acting

3. corporations commit a crime whenever one of its employees does, on the condition that the employee acts

4. corporations commit crimes whenever an employee of those corporations commit a crime, if it was while acting

5. the corporation whose employees commit a crime, commits a crime, whenever the employee acted

答案选A，我没有异议 ---- 不过要问一下，acted / benefited 是什么结构？

我觉得不能理解成一般过去时，难道是被动式，should be被省略？？？？不太理解，请NN指教

这里就是一般过去式，表示过去已经发生的行为

表示员工确实acted within the scope of ....和the coorporation 也确实是benefited。强调动作的已经发生
