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

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

(D)
     one man was thrown straight into the air by the upward thrust, and hours before the temblor strange electromagnetic signals were detected

(E)
     one man who was thrown straight into the air by the upward thrust, and strange electromagnetic signals that were detected hours before the temblor

The correct answer will maintain parallelism in a coordinate series. Three mysteries are mentioned, and the first establishes the form required for the other two members of the series, a noun phrase introduced by the (the unexpected power ...). A, the best choice, correctly uses noun phrases introduced by the for the second and third members of the series (the upward thrust... and the strange electromagnetic signals ...).
   Choice B substitutes a clause (strange electromagnetic signals were detected...) for the third noun phrase, and C and D use clauses instead of noun phrases for both additional members of the series. E uses two noun phrases, but they are not intro­duced by the. Furthermore, the phrase one man who ... does not logically identify one of the mysteries

1。请问大家黄色部分是说明这几个成分前面有the，从而形成了名词短语的并列么？

2。这个并列结构中
                    the upward thrust that threw one man straight into the air.
                    是从句修饰名词，前面是形容词修饰名词，这两个结构可以并列？

3。the strange electromagnetic signals detected hours before the temblor.不是句子么，为什么可以并列？

不是一定要有the的，名词的平行，我觉得平行都要满足两点，

一，结构平行，二，意思平行

二者不分先后，必须同时满足

可以，结构上来说都是名词短语，怎么被修饰不用考虑

不是句子，detected作形容词修饰signals

I got it

thanks!
