4.According to the passage, which of the following is true of the unemployment rates mentioned in line 15?
这个题是个坑爹的题，They give less than a full sense of the impact of unemployment on working-class people.肯定没有问题。你的定位本身也没有错。是说unemployment讲的不够全面。你标黄色的就体现这个意思。(D) They have been considered by many historians to underestimate the extent of working-class unemployment.的问题就在 many historians 。文中challenge Keyssar的是作者，并不是很多historians。

7.The author views Keyssar’s study with  (E) qualified admiration。skepticism是什么意思？如果选skepticism是说作者对这个Keyssar是怀疑的，认为它不可靠。你看Keyssar also scrutinizes unemployment patterns according （第三段），这个就是表扬，第四段更明显。scrutinize：褒义词。一般来说作者总会态度鲜明，一般选有保留的支持或反对，怀疑的态度一般都是不确选项。

比如是大体上支持，部分质疑，答案就是支持的选项呢？comments:那肯定是支持,所以答案是有限度的支持：qualified admiration
