　　(C) an expanding cloud of energized particles ejected from the Sun recently triggered a large storm in the magnetic field that surrounds Earth, brightening the Northern Lights and possibly knocking out
　　(D) a large storm in the magnetic field that surrounds Earth, recently triggered by an expanding cloud of energized particles, brightened the Northern Lights and it possibly knocked
　　(E) a large storm in the magnetic field surrounding Earth was recently triggered by an expanding cloud of energized particles, brightening the Northern Lights and it possibly knocked
C里面brightening和knocking是伴随结构，根据CD的那本书，伴随结构的主语论元是主句主语，那么这样的话它的主语论元不应该是an expanding cloud，为什么解释说它修饰的是storm？我哪里理解出错了
