问题 The word "ephemeral" in the first paragraph probably means
We can learn from the fifth paragraph that

选项 A、US Bureau of Labor Statistics offers inaccurate statistics.
B、Mr. Dychtwald objects to the authors’ opinion.
C、the US labor force will either rise greatly or fall sharply.
D、statistics can be used to support different opinions.

答案D

解析 本题是细节题。直接定位至第五段。末句指出“首先这是些数据,之后才是你想用它们来证明什么”,这说明数据是有选择地为人所用,这正是[D]表达的内容,故为答案。由该句可知,不同的人对数据有不同的解释,这并非是US Bureau of Labor Statistics提供的数据不准确,只是人们的立场不同而已,排除[A]。首句指出 both sides cited the US Bureau of Labor Statistics in support of their case,可以判断后面提到的两个人是观点对立的双方。由上一段可知Mr. Cappelli认为该书观点不正确,可以判断这里他是反对的一方,而Mr. Dychtwald则是持肯定态度的一方,[B]与此矛盾,排除。[C]中的rise greatly和fall sharply在该段没有提及,排除。
