Critical Reasoning
试题详情
题目：
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?
选项:
A、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.
B、Among whale fossils that date from later than about fifty million years ago, none are fossils of whale species that drank only fresh water.
C、Fossils of whale species that drank fresh water will not be found in close proximity to fossils of whale species that drank salt water.
D、The earliest whales that drank salt water differed from fresh-water-drinking whales only in their possession of specialized kidneys.
E、Between sixty million and fifty million years ago, the freshwater lakes and rivers in which whales originated were gradually invaded by salt water.
答案:
A
提问：
请问唐瑭老师，这道题我看题目是要我们读全部内容，然后根据它里面的时间选出A和E，因为这两个选项里的时间是between 60 million years and 50million years，在文章里说的时间的范围内。接着我看E选项说的whale、salt water和lakes and rivers，感觉E选项更近，就选了E。

提问：
这道题做的时候一开始其实把A排了 但是看后边的4个更不靠谱 于是又选了A 我觉得是由于我没有读出A事件的性质导致我讲A排除 我A读的是那些化石不能在原文说的其他地方被发现 请管老师指教 谢谢
