今天复习到169题，晕了。

169. Seismologists studying the earthquake that struck northern California in October 1989 are still investigating some of its mysteries: the unexpected power of the seismic waves, the upward thrust that threw one man straight into the air. and the strange electromagnetic signals detected hours before the temblor.

(A)              the upward thrust that threw one man straight into the air, and the strange electromagnetic signals detected hours before the temblor

(B)              the upward thrust that threw one man straight into the air, and strange electromagnetic signals were detected hours before the temblor

我觉得A平行，可是我一看到B是个句子就选了。冒号后面可以接短语就行是么？答案A

lxr027

冒号后面的内容是对mysteries的解释：the unpxpected power ，the upward thrust ,the stranger electromagnetic signals 构成parallelism 结构，B选项中，最后的完整句子很明显破坏了parallelism结构啊

dingxiang

冒号后面是可以只跟名词的

lxr027

名词性短语吧
