大全-5-19. 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.

答案是A
我選的答案是E
我想的是：題目說1982年到1995年受雇人口的增加是因為低薪資的受雇人口增加，所以我選得答案是，低薪資受雇人增加率總體的增加率，請問這樣想錯在哪裡呢？

1982到1995就業人數最大的增加是低薪資的服務業, 但並沒有增加低薪資服務業在全部的就業的比例, 高薪資服務業反而會增加

我覺得要形成這種情況只有一開始低薪比高薪的多 但高薪的成長率比低薪的大 但高薪最後總增加數量又不會超過低薪的情況才會成立(因為在這段期間低薪還是要佔比較多數量)
舉例：1982年低薪加入了200人高薪有100人總共300 低薪佔2/3, 高薪佔1/3 到了1995年高薪成長了50人變成150, 低薪成長10人 總人數的增加還是低薪多 但是比例上低薪卻降低了～
如果選E低薪成長率比總體成長率高 那就違反他比例降低的說法了
希望沒理解錯
