rotating independently of and more quickly than Earth's outer layers做INNER CORE的定语，语法上没有问题，但是discovery的内容被改变了，discovery是要强调core的这个动作而不是只说明这里有个core。

and 前后不平行： 前：how 引导句子，后：名词词组；不对称； rotating 分词修饰歧异，既可以修饰core,也可以修饰The discovery

and 前后是名词词组和句子，不平行 rotate 修饰不清

rotating形容的是the discovery that Earth's inner core, 不是只有inner core，所以DE都是错误选项
