19. Recent estimates predict that between 1982 and 1995 the greatest increase in the number of people employed will be in the category of low-paying service occupations. This category, however, will not increase its share of total employment, whereas the category of high-paying service occupations will increase its share.
If the estimates above are accurate, which of the following conclusions can be drawn?
(A) In 1982 more people were working in low-paying service occupations than were working in high-paying service occupations.
(B) In 1995 more people will be working in high-paying service occupations than will be working in low-paying service occupations.
(C) Nonservice occupations will account for the same share of total employment in 1995 as in 1982.
(D) Many of the people who were working in low-paying service occupations in 1982 will be working in high-paying service occupations by 1995.
(E) The rate of growth for low-paying service occupations will be greater than the overall rate of employment growth between 1982 and 1995.
If the estimates above are accurate, which of the following conclusions can be drawn?
根据题目这个是must be true题型，也就是所有的信息必须从原文中得到或者推出，不能有new information加入
分析原文的话；
1. Recent estimates predict that between 1982 and 1995 the greatest increase in the number of people employed will be in the category of low-paying service occupations,也就是说在这个时间段里，low paying 的人数增加是最多的（注意这里是人数，而不是百分比）
2.This category, however, will not increase its share of total employment表示虽然low paying的人数增加了，但是其（low pay）相对于total employment的百分比没有增加
3. whereas the category of high-paying service occupations will increase its share---high pay的百分比增加了
因此看
(A) In 1982 more people were working in low-paying service occupations than were working in high-paying service occupations.可以对应原文的（the greatest increase in the number of people employed will be in the category of low-paying service occupations）
(B) In 1995 more people will be working in high-paying service occupations than will be working in low-paying service occupations. 和原文相反了
(C) Nonservice occupations will account for the same share of total employment in 1995 as in 1982. 原文没有给出过这个信息，关于是否non service occupationsxxx，原文的信息也不能作为evidence 能够推出这个结论
(D) Many of the people who were working in low-paying service occupations in 1982 will be working in high-paying service occupations by 1995原文给的信息，也没有提到：工作在low pay的人会work as high pay service
(E) The rate of growth for low-paying service occupations will be greater than the overall rate of employment growth between 1982 and 1995.原文连overall rate of employment growth都不知道，所以这个greater than的比较不成立，原文的信息不能infer作者: shelvey 时间: 2012-4-24 06:50
