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.

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


Number vs. Percentage.
Low paying --> highest number increase, but not % share increase.
High paying --> % share increase.

Thus, % low paying out of previous total (low paying + high paying) was higher than % high paying.
For example, 10 for high paying but 990 for low paying. only 1% of high paying and 99% for low paying.
Let's say 5 high paying increased, and 10 low paying increased. Now, 15 + 1000 = 1015. 1.5% for high paying or 50% growth for high paying. Whereas, the share % of low paying decreased to 98.5%.

So, probably A would be the answer.

IMO A)

Even if share is less the number of people grown can be more

If the estimates above are accurate, which of the following conclusions can be drawn?

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

IMO 'E'

As stated in the passage ..... "between 1982 and 1995 the greatest increase in the number of people employed will be in the category of low-paying service occupations"

As the no. of low-paying jobs(occupations) have increased the most from 1982 to 1995 .... they should be more than overall employment growth (as some other types of jobs might have lower growth or negative)
They should be more than the overall jobs growth .... and its stated in E.

what is OA?

I completely agree with amit's explanation.

I am not clear with the following in Richardson's explanation

"Thus, % low paying out of previous total (low paying + high paying) was higher than % high paying."

This will contradict the argument. The argument says that share of employement under this category did not increase.
