Recurrence rates of earthquakes can help predict future quakes because ______.
A．improvement in mathematics allows figures to be very accurate
B．this method has been used since ancient times and proved very effective
C．most scientists focus their investigations on the quakes of certain areas
D．continuous plate movements often result in earthquakes in certain areas请帮忙给出正确答案和分析，谢谢！
参考答案
正确答案：D
解析：由题干中的Recurrence rates of earthquakes定位到原文首段第三句One prediction technique involves an analysis of the recurrence rates of earthquakes as indicators of future activity．[精析] 原因目的题[考频：24]。原文首段最后两句说“一种预测技术是把对地震重现率的分析作为未来地震活动的指示器。地震总是集中在受到地球板块持续运动影响的特定区域，科学家把他们的研究集中在这个特定区域”。由此可知，重现率可以帮助预测以后的地震，因为持续的板块运动通常在特定区域造成地震。D)与之相符，故为正确答案。[避错] 原文并未提及数学上的改进及其对数据准确性的帮助，排除A)；由原文可知；此方法并非从古应用至今，原文也并未提及其非常实用，排除B)；C)没有明确说明是原文提及的“受到地球板块持续运动影响的特定区域”，只是一个模糊的说法，故排除。
