WhichofthefollowingfactorswasultimatelyresponsibleforthefallofthecivilizationofancientEgypt?

【单选题】

A.Changeofclimate.

B.Famine.

C.Flood.

D.Populationgrowth.

正确答案:

A

答案解析:

A：

气候的变化。

第一段中有这样一个子句…ashiftinclimate…wasultimatelytoblame…最终须归咎于气候的变化。

在第一题的题解中，我们提到了“饥荒”与“古埃及文明毁灭”的关系。

但“饥荒”是表层的因素，“气候的变化”才是古埃及文明毁灭的深层的因素。

因此A是正确的答案。

B：

饥荒。

C：

水灾。

D：

人口增长。

A.which

B.that

C.this

D.what

B

本题有点难度，考查强调句的用法，Itis+被强调的部分+that/who+…，此处是强调事物，所以用代词that，答案是B。
