To map Earth's interior, geologists use a network of seimometers to chart seismic waves that originate in the earth's crust and ricochet around its interior, most rapidly traveling through cold, dense regions and slower through hotter rocks.
A) interior, most rapidly traveling through cold, dense regions and slower
B) interior, which travel most rapidly through cold, dense regions, and more slowly
C) interior, traveling most rapidly through cold, dense regions and more slowly
D) interior and most rapidly travel through cold, dense regions, and slower
E) interior and that travel most rapidly through cold, dense regions and slower


不是很懂og解释A选项rapidly和slower不平行在哪儿，假如都是adv的话。按照RON平行课程的讲解，从右往左看，我理解的是因为slower后面没有对应traveling的动词，不知道这样理解对不对？还有说正确的C选项，这里的traveling是modify seismic waves吗？

To map Earth's interior, geologists use a network of seimometers to chart seismic waves that originate in the earth's crust and ricochet around its interior, most rapidly traveling through cold, dense regions and slower through hotter rocks.
原句的that后面的句子修饰seismis wave, 所以traveling是对应seismis wave 的。
A) interior, most rapidly traveling through cold, dense regions and slower
most rapidly traveling 错误因为most在这指大部分的seismis waves，这改变了原句的意思.  most在这可以用some取代，

B) interior, which travel most rapidly through cold, dense regions, and more slowly
which 指的是interior 还是richochet, or sw?
C) interior, traveling most rapidly through cold, dense regions and more slowly
Correct, traveling 指的是seismis waves。seismis waves 在cold dense regions 跑得最快，在hotterrocks跑得慢些。

D) interior and most rapidly travel through cold, dense regions, and slower
slower 是用在比较两样东西,，要用slower than 这里只有seismis waves一样东西， 没能比较。

E) interior and that travel most rapidly through cold, dense regions and slower看D

这道题还有一个不太明白的地方时为什么cold和dense之间没有and连接啊？感觉好像故意给别人造成后面cold dense slower平行一样。。。

不喜欢乱起名字

可是og里的解释 The action, ricochet,

说明traveling解释修饰了ricochet这个动词，而非seismic waves，但这个traveling...的逻辑主语应该是seismic waves，有点不懂comma + ving 为什么也能修饰动词，还是说它只是修饰了前面这整个句子

关于C选项有个问题，就是不是说comma+doing就是修饰前面主句的主语嘛？那这里traveling不就是修饰geologists了么？
