The second paragraph implies that
[A] the world’s earthquake laboratories were not effective in detecting seismic "pre-shocks".
[B] seismic signaling was the major communication form of many animal species.
[C] those animal species can feel and understand all kinds of vibrations.　　
[D] all strange animal behaviors can be explained by extra-sensory perception.

参考答案A
解析:译文


【定位】根据题干直接定位到第2段。
【解析】第2段第1句用missed by表明精密的震动监测仪都无法测出地震前震，而第2句却说动物有可能察觉地震前震，由此可推断出全世界的地震实验室在探测地震前震方面并不高效(not effective)，因此应选A。
