标题: GMAT-27-22请教求解思路

Whales originated in the freshwater lakes and rivers of ancient Asia about sixty million years ago. Not until about ten million years later did species of whales develop specialized kidneys enabling them to drink salt water. Although fossil evidence shows that some early whale species that lacked such kidneys sometimes swam in the Earth’s saltwater oceans, these species must have had to return frequently to freshwater rivers to drink.

Which of the following is most strongly supported by the information given?

Fossils of whale species dating from between sixty million and fifty million years ago will not be found on continents that were at the time separated from ancient Asia by wide expanses of ocean.

Among whale fossils that date from later than about fifty million years ago, none are fossils of whale species that drank only fresh water.

Fossils of whale species that drank fresh water will not be found in close proximity to fossils of whale species that drank salt water.

The earliest whales that drank salt water differed from fresh-water-drinking whales only in their possession of specialized kidneys.

Between sixty million and fifty million years ago, the freshwater lakes and rivers in which whales originated were gradually invaded by salt water.

C, 尽管有些化石是在有盐水的地方，但喝淡水的不和他们在一起。

我也看不太懂,可以详细解释一下吗?

E吧,不然它怎么在盐水里面玩玩,淡水里面喝喝

这个题的答案显然是A

没有specialized kidneys 的whales在fifty million years ago 不可能游的很远。

再次感谢楼主！呵呵，题目多的有点做不过来啊。

谢谢5楼的解释，现在明白了。答案A的句子不太好懂阿。这几天感觉做逻辑题看选项时，要先看句子的主干，然后再看修饰成分（定语或状语），这样不至于被ETS给弄晕，发现好多题目全可以这样快速解决。

看来好像有点不沾边，实际上用了文中最多的信息。正是因为海水里游游，淡水里喝喝，所以不能离开淡水很远，被海洋隔开的太原就不可能到达。想到奇怪的问题，要是说鲸鱼在水下呆不长，就的浮上水面呼吸，这样是可以到很远的呵呵呵呵胡言乱语
