大全-5-19答案有错误？

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.

标准答案是A。但是我觉得没有哪个选项是正确的。根据题目的意思，我们可以设想，82年1千万劳动大军中，有1百万低收入服务从业人员，还有1百万高收入服务从业人员。到了95年，劳动大军变成了2千万，低收入的增加到2百万，高收入的增加到3百万。因此低收入的数量增加，但比例没变；而高收入的比例增加了。但是我们并不能推出82年低收入的比高收入的人就多。因为按照假设两者是相等的。
我觉得这个题目的正确答案应该是95年高收入的人的数量比82年高收入的人的数量要多。因为基数变大了，比例还增加了，自然数量变大了。
请大家讨论一下，这个题目是否有错误？

耳朵，你的假设不成立，因为这段


the greatest increase in the number of people employed will be in the category of low-paying service occupations.


高收 数量增长低于 低收。如果百分比增长快于 低收 的话，就只能是说1982年低收数量高于高收。希望你明白我的意思
