大全 TEST 5 19

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.（A）

(E) The rate of growth for low-paying service occupations will be greater than the overall rate of employment growth between 1982 and 1995.

答案是A，但是我想问的是，题目只是说了低收入的就业人数增多了，并不就能说明低收入的人数比高收入的要高啊？可能是我没有理解However后面的话吧。请指教

我选的是D，有什么问题？多谢

这题有点难

答案是A,是一个完全得数学问题，你用代数式详细算一下。如果没有A（基数大），低收入服务部门增长量比高收入服务部门高，那么份额增长也应该比之高

D 原文不可能得出这样得结论，和原题得逻辑过程毫无关系。
