The discovery that Earth’s inner core rotates independently of and more quickly than Earth’s outer layers is responsible for advancing studies of the flow of heat from the inner through the outer planet and of the formation and periodic reversal in direction of Earth’s magnetic field.

A.core rotates independently of and more quickly than Earth’s outer layers is responsible for advancing studies of the flow of heat from the inner through the outer planet and of the formation and periodic reversal in direction of Earth’s magnetic field

B.core rotates independently of and more quickly than Earth’s outer layers is responsible for advancing studies of how heat from the inner core flows through the outer planet, and the formation and periodic reversal in direction of Earth’s magnetic field

C.core rotates independently and more quickly than Earth’s outer layers are responsible for advancing studies of how heat from the inner core flows through the outer planet, and how Earth’s magnetic field forms and the periodic reversal of its direction

D.core, rotating independently and more quickly than Earth’s outer layers, are responsible for advancing studies of the flow of heat from the inner through the outer planet, and the formation and periodic reversal in direction of Earth’s magnetic field

E.core, rotating independently of and more quickly than Earth’s outer layers, is responsible for advancing studies of the flow of heat from the inner through the outer planet and of how Earth’s magnetic field forms and the periodic reversal of its direction

能不能分析一下A\B\D这三个选项？

我觉得是A，DE选项可以排除，rotating做状语，修饰the discovery不对。B选项后半部分，of how heat from the inner core flows through the outer planet和the formation and periodic reversal in direction of Earth’s magnetic field不平行。只有A是对的

同意选A
1.主谓一致：主语是the discovery, 谓语是be responsible for， 所以应用is,排除CD
2.平行：study of后有and的平行，介词最后不省略，E是of the flow 与of how平行， 即名词与从句平行，错，排除E
B中，and the formation前的逗号多余，两个主句并列的and前才加逗号，这里去掉逗号才对，所以排除
而且A中，studies of the flow与of the formation and periodic reversal都是介宾短语，平行了，所以选A
