题目

What does the professor imply about the lack of water buffalo and hippopotamusfossils in the more recent lakes?

The level of water in the lakes was not sufficient for these animals.

The bottoms of the lakes were too sandy for these animals to stand in.

The location of the lakes made them too difficult of these animals to reach.

The vegetation near the lakes did not attract these animals.

题目解析

根据教授所说：However, at the sites of the more recent lakes, there’re only cattle fossils…because cattle only use water for drinking. 由此可知，在近代形成的湖泊遗址中，发现有 cattle 的化石，没有 buffalo 和 hippopotamus的化石，这证明近代湖泊可能既小又浅，因为 cattle 只需要饮水，不像 buffalo 和 hippopotamus 一样需要生活在水中。选项 A 说法符合原意，为正确答案。

答案: A
