not only did space shuttle astronauts retrieve an orbiting satellite, it was done simultaneously while avoiding
not only was an orbiting satellite retrieved by space shuttle astronauts, but they also simultaneously avoided
an orbiting satellite was retrieved by space shuttle astronauts who also avoided simultaneously
space shuttle astronauts retrieved an orbiting satellite, simultaneously while avoiding
space shuttle astronauts retrieved an orbiting satellite and simultaneously avoided
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
AB很好排除，not only but also结构错误；顺带排除C，主语应该是space shuttle astronauts才能承接前面的Performing a risky maneuver that required precision flying；
DE，D其实翻成中文会好理解很多，「同时正在避开」avoiding being rear-ended by a passing ultraviolet telescope.（感觉只有正在行驶才能这么说）；
因为都是发生在过去，也不是过去的某个时间段正在避开，没有必要用while。另外也有答案说simultaneously while语义重复的（但之前有道讲化肥的题目应该也是prep2007的，也有at the same time while 同时使用的现象）
如果是真的，就当个小考点记住吧·····
