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.
the upward thrust that threw one man straight into the air, and the strange electromagnetic signals detected hours before the temblor
the upward thrust that threw one man straight into the air, and strange electromagnetic signals were detected hours before the temblor
the upward thrust threw one man straight into the air, and hours before the temblor strange electromagnetic signals were detected
one man was thrown straight into the air by the upward thrust, and hours before the temblor strange electromagnetic signals were detected
one man who was thrown straight into the air by the upward thrust, and strange electromagnetic signals that were detected hours before the temblor
三者并列，注意平行
没看到平行，这后面的题真是一不小心就错了
我一开始没看见从平行 想成从逻辑上去了....
some of its mysteries被解释为三个并列的成分：x,y,z，所以他们三个都应该是名词，或名词短语，符合平行结构；
B选项：strange electromagnetic signals前面少了the, 后面是v+done,构成独立的句子了，不符合平行结构；
C选项：不平行
DE选项：不平行
