概括大意与完成句子

Paul Wignall from the University of Leeds was investigating the link between volcanic eruptions and mass extinctions. Not all volcanic eruptions killed off large numbers of animals, but all the mass extinctions over the past 300 million years coincided with huge formations of volcanic rock. To his surprise, the older the massive volcanic eruptions were, the more damage they seemed to do.

The main idea of this paragraph is__________.

 A、Association of Mass Extinctions with Volcanic Eruptions

 B、Killing Power of Ancient Volcanic Eruptopms

 C、A Mass Extinctions

 D、Volcanic Eruptions That Caused No Mass Extinction

【正确答案】 A

【答案解析】 本段文字的第一句话:Paul Wignall from the University of Leeds was investigating the link between volcanic eruptions and mass extinctions.里兹大学的Paul Wignall正在研究火山爆发与物种大量灭绝的联系。The association of mass extinctions with volcanic Eruptions与the link between volcanic eruptions and mass extinctions在意思上是相同的。答案是A。
