问题 Recurrence rates of earthquakes can help predict future quakes because ______.
Which of the following is used by modern scientists to indicate a coming earthquake?
选项 A、The crying of dogs.
B、The conductivity of rocks.
C、The changes in the water table.
D、The quantity of fluid in earth.
答案B
解析 由题干中的to indicate a coming earthquake定位到原文第二段第二句... modern scientists have focused on physical evidence for a coming earthquake．[精析] 事实细节题[考频：51]。原文第三段首句说Analysis of the changes in magnetic properties and conductivity of rocks provides further data for prediction．对岩石的磁性和导电性变化的分析提供了更多的预测数据，故B)“岩石的导电性”包含在内，为正确答案。[避错] A)是古希腊和罗马人的做法，排除；C)地下水位的变化是导致岩石含水量变化的原因：且为非地震原因，非题干要求的依据，排除；原文提到可以帮助预测地震的是“石头里液体的含量”，而不是“土壤里液体的含量”，也排除D)。
