According to scientists who monitored its path, an expanding cloud of energized particles ejected from the Sun recently triggered a large storm in the magnetic field that surrounds Earth, which brightened the Northern Lights and also possibly knocking out a communications satellite.
87. According to scientists who monitored its path, an expanding cloud of energized particles ejected from the Sun recently triggered a large storm in the magnetic field that surrounds Earth, which brightened the Northern Lights and also possibly knocking out a communications satellite.
(A) an expanding cloud of energized particles ejected from the Sun recently triggered a large storm in the magnetic field that surrounds Earth, which brightened the Northern Lights and also possibly knocking
(B) an expanding cloud of energized particles ejected from the Sun was what recently triggered a large storm in the magnetic field that surrounds Earth, and it brightened the Northern Lights and also possibly knocked
(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
(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

the"comma + ing" modifier should only be used when:
(A)
itMODIFIES THE ENTIRE ACTION of the preceding clause, and it APPLIES TO THESUBJECT of that clause;
AND
(B)

-i got a 100 on the most recent exam, bringing my average up to 91
按OG的解释来说,The timing and logical relationships among the events described in this sentence are of utmost importance. The scientists monitored a cloud ejected from the Sun. The cloud triggered a large storm, whose consequences were the brightening of the Northern Lights and the possible knocking out of a satellite. The latter two events are in a conjunction, so they should be represented by similar verb forms. 换句话说,brightening ... and knocking ... 是the cloud triggered a large storm的伴随结果,无逻辑主语。在-ing做状语时,逻辑主语的判断:
