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.

答案为什麽是A呢？想不通，D 怎麽不对呢

簡單整理一下题目 :

3年内

投入 low-paying service 的人数 (注意 是数量) ↑ 占整体的比例 the same

high-paying service的人数 (题目没交代) ？ 占整体的比例 ↑

雖然題目沒有說明,但現實生活中這種數據上的變化,應該不可能是同一批人上的異動,新增加了勞動人口影響了整體數據分析的可能性較大

(D)選項我試著用數據算來算去….都算不出一個合理的數字來

不知harvardstudent 選(D) 的想法是???
