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.

题目分析：
本题划线部分虽然很长，但是变化的内容并不多。我们可以在划线部分的后半段发现平行制造者and。其连接的两者需要在逻辑上和语形上保持一致。这一点就能排除掉不少选项。
选项分析：
A选项：首先，which brightened the Northern Lights是定语从句，also possibly knocking out a communications satellite是分词短语，应是伴随状语，两者无法保持平行。
其次，本选项真正的错误出现在which brightened the Northern Lights这个定语从句的先行词上。在语法上其先行词为最近的名词，即，Earth。但在逻辑上，真正能点亮北极光的应该是an expanding cloud of energized particles。（knocking out a communications satellite的逻辑主语错误与本选项同理）
B选项：本选项没有语法错误，干扰性较强。代词it的指代对象为an expanding cloud of energized particles，这是没有问题的。但是，此处的“点亮北极光”和“使卫星失效”应该用伴随状语的形式，不能用合句的形式。在本题中，“电子云引起了地球周围的磁场风暴”实际上是“点亮北极光”和“使卫星失效”的根本原因，因此“电子云引起了地球周围的磁场风暴”和“使卫星失效”不能是并列关系，必须是有强有弱的主从关系。即，“电子云引起了地球周围的磁场风暴”为主句，“点亮北极光”和“使卫星失效”为从句（伴随）。
C选项：Correct. 本选项在语法和逻辑上均是正确的。
D选项：brighten和knock out在本选项中的发出者为a large storm，但在逻辑上，应该是an expanding cloud of energized particles点亮了北极光和切断了信号，不是暴风雨；另外，brighten和knock out应是trigger的伴随状语错误同(B)。
E选项：brighten和knock out都应是trigger的伴随状语，两者应该保持语法上的平行。
毕出老师，不是定语从句的先行词只要在句子中能找到合理的指代对象就可以了吗，A选项中的which能找到an expanding cloud of energized particles呀，为何一上来就用就近修饰把A选项排除了，是我哪里把这个知识点理解错了吗？which的指代只能在同一层级，不能跳跃层级修饰？还是跟it这种代词一样，只要句中出现合理的指代对象就好，虽然A选项which即使指代an expanding cloud of energized particles，也无法表达出动作之间的逻辑关系而排除，但对于定语从句先行词的指代问题我一直有疑惑，有些题目里你直接就可以用就近修饰排除，有些题目里又说不可以排除，请毕老师帮忙解答一下
