问题 PASSAGE THREE
Why did modern humans survive the successive volcanic eruptions?
选项
答案Because of their fallback populations in Africa and Asia．
解析 为什么现代人类能经历了密集的火山爆发而幸存下来?文章第一段结尾处就指出“Modern humans，though，squeaked by，thanks to fallback populations in Africa and Asia，researchers say．”此处squeak by就表示“对付过去”，原因在于thanks to后面引出的原因“其在非洲和亚洲的广大人口储备”。
