Geologists believe that the warning signs for a major earthquake may include sudden fluctuations in local seismic activity, tilting and other deformations of the Earth’s crust, changing the measured strain across a fault zone and varying the electrical properties of underground rocks. (A) changing the measured strain across a fault zone and varying (B) changing measurements of the strain across a fault zone, and varying (C) changing the strain as measured across a fault zone, and variations of (D) changes in the measured strain across a fault zone, and variations in (E) changes in measurements of the strain across a
fault zone, and variations among

ABC都排除了,DE纠结 其实没看懂D在说什么。。 我的理解:在fault zone的张力测量的变化
为什么选E呢?
