Surveys indicate that 52 percent of all women aged eighteen to sixty-five are in the labor force (employed outside the home) in any given month. On the basis of these surveys, a market researcher concluded that 48 percent of all women aged eighteen to sixty-five are full-time homemakers year-round.
Which of the following, if true, would most seriously weaken the researcher's conclusion?
(A) More women are in the labor force today than during any other period since the Second World War.
(B) Many workers, both men and women, enter and exit the labor force frequently.
(C) Although only a small sample of the total population is surveyed each month, these samples have been found to be a reliable indicator of total monthly employment.
(D) Surveys show that more women than ever before consider having a rewarding job an important priority.
(E) Women who are in the labor force have more discretionary income available to them than do women who are not.
52% women are in labour force in any given month.
Conclusion: 48% women are full time homemakers year-round.
There are multiple issues with this conclusion, right?
They may not be homemakers. They may be studying.
They may not be homemakers and might be doing some other non-economic activity.
They may not be homemakers all year round - perhaps they work outside home for 4 months in a year.
(B) Many workers, both men and women, enter and exit the labor force frequently.
This supports our theory that they may not be homemakers are year round. What if the 52% number constitutes different people every month? Say one woman works outside every alternate month (Jan, March, May ...) and another woman works outside other alternate months (Feb, April...). Then overall numbers don't change but neither woman in a full time homemaker.
Hence (B) weakens our conclusion.
