[求助]OG11 71修饰问题

chen83250245

71. The cameras of the Voyager II spacecraft detected six small, previously unseen moons circling Uranus, which doubles to 12 the number of satellites now known as orbiting the distant planet.

A. which doubles to 12 the number of satellites now known as orbiting

B. doubling to 12 the number of satellites now known to orbit

C. which doubles to 12 the number of satellites now known in orbit around

D. doubling to 12 the number of satellites now known as orbiting

E. which doubles to 12 the number of satellites now known that orbit

这题有点不理解OG的解释，分词作状语可以修饰整个句子的吗？我觉得doubling的逻辑主语应该是那六个小月亮吧，如果是的话，那怎么能把把修饰语的位置放在那呢？觉得有点怪~~请大家帮忙解答

which 引导的句子修饰它前一个词语，这题用which的话，即在修饰ＵＲＡＮＵＳ，和原文意思违背．

doubling现在分词引导的状语从句是对前面整个句子的补充，发现了６个小月亮这件事，让卫星数增加了一倍．

看了携影的总结，说这题的一个考点是E选项中的that不能做主语？有没有谁能解释一下这么that为什么不能做主语，这不是一个定语从句吗？

谢谢！～
