【求解】一道SC的平行问题

A.not only did space shuttle astronauts retrieve an orbiting satellite, it was done simultaneously while avoiding

B.not only was an orbiting satellite retrieved by space shuttle astronauts, but they also simultaneously avoided

C.an orbiting satellite was retrieved by space shuttle astronauts who also avoided simultaneously

D.space shuttle astronauts retrieved an orbiting satellite, simultaneously while avoiding

E.space shuttle astronauts retrieved an orbiting satellite and simultaneously avoided

这道题的答案是E，其它选项的错误我都明白，但是在E选项中，根据Ron神讲过的平行规则，and右边的东西不是应该一模一样在右边能找到吗？ 在这个E中，and后面是simultaneously avoided 是adj.+verb. ，但是在前面只有一个retrieved没有adj，这样的话是不是这个平行结构也有问题呢？求解 谢谢！！
