But then the argument says that the percentage of ALL women in the workforce. So let's say that, for example, 7 percent of the women in the labor force were employed in the service industry in 1985. Then in 1995, 17 percent of the women in the labor force were employed in the service industry. Notice, the argument never said that 17 percent of the labor force IN THE SERVICE INDUSTRY are women. Rather, it said that 17 percent of ALL the WOMEN in ALL the LABOR FORCE are women. Wouldn't it make sense to see whether the total population of all the women in ALL the labor force increased or decreased? because that can truly determine whether the number of women in the service industry truly increased.
Tarek, while I choose D first, I agree with you that the answer D does need an extra assumption.
The "proportion" here relates to the mix of men and women:
Women make up a larger proportion of workers in the IT sector (than men do).
Assumption: the number of female workers and male workers did not decrease (at least stayed the same) from 1985 to 1995
1985: 7% of women workers were in IT (say 7 of all 100 female workers)
1995: 16% of women workers were in IT (say 16 of all 100 female workers)
1985: 10% of men workers were in IT (say 10 of all 100 male workers)
1995: 34% of men workers were in IT (say 34 of all 100 male workers)
1985: 7female, 10male - 35% of workers in IT were women
1995: 16female, 34male - 32% of workers in IT were women.You need the % of men in the industry to get the above red portion
Now for ALL of this to make sense, the
assumption needs to be made that the general number of female and male workers was on an upward trend.
