To map Earth’s interior, geologists use a network of seismometers 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

正确选项是C，其他倒是明白，但是through cold, dense regions这个地方cold和dense都是去修饰regions的吧，不应该用and连接平行吗？可以这样直接用逗号隔开吗？谢谢大家。大概这个问题很弱智吧hhh
