It is clear that the nation’s labor force will diminish during the next 20 years. Population growth in our country reached its apex in 1961, and by the late 1960s more heads of households were employed in this country than ever before. This growth rate has slackened significantly, and by 1995 the number of households overall will be reduced, thus decreasing the number of potential employees in the work force.

Which of the following, if true, would most seriously weaken the conclusion drawn above?


1) Employers who do not wish to scale back the size of their operations will have to pursue qualified employees more aggressively after 1995.

2) Experts predict that after a downturn in the quality of employee benefits during the 1980s and early 1990s, the overall quality of benefits offered to employees will rise by 1995.

3)The proportional representation of heads of households in the labor market increased between the years 1988 and 1992.

4)It has become progressively harder since the 1960s for households to subsist on a single earner’s pay, so an increasing proportion of the labor market are those who are not heads of households.

5) By 1995 there will be far more people managing their own businesses than there have ever been previously.

Conclusion: the nation’s labor force will diminish during the next 20 years.
Premise 1: Population growth in our country reached its apex in 1961, and
Premise 2: by the late 1960s more heads of households were employed in this country than ever before
Premise 3: the growth rate has slackened significantly
Premise 4: by 1995 the number of households overall will be reduced
Intermediate Conclusion : thus decreasing the number of potential employees in the work force.

Which of the following, if true, would most seriously weaken the conclusion drawn above?


1) Employers who do not wish to scale back the size of their operations will have to pursue qualified employees more aggressively after 1995.
This would be a probable consequence if the conclusion is true, but has no bearing on the validity of the conclusion itself.

2) Experts predict that after a downturn in the quality of employee benefits during the 1980s and early 1990s, the overall quality of benefits offered to employees will rise by 1995.
Quality of employee benefits is not relevant to whether the workforce will decrease or not.

3)The proportional representation of heads of households in the labor market increased between the years 1988 and 1992.
This indicates that a higher percentage of the market were HoH in 1992 than in 1988. This does not weaken the argument that the labor force will diminish.

4)It has become progressively harder since the 1960s for households to subsist on a single earner’s pay, so an increasing proportion of the labor market are those who are not heads of households.
This is the correct answer. The argument is largely based on the intermediary conclusion that there will be less potential employees in the workforce, which is based on premise 4 (that there will be less households). Answer choice 4 weakens this.

5) By 1995 there will be far more people managing their own businesses than there have ever been previously.[/quote]
Doesnt have any bearing on the size of the workforce.

I agree with D "4" being the correct choice. Good explanation by Jko

Conclusion: the nation’s labor force will diminish during the next 20 years.

1) Employers who do not wish to scale back the size of their operations will have to pursue qualified employees more aggressively after 1995.

-Employers pursuing employees has no bearing on argument. If anything strengthen.

2) Experts predict that after a downturn in the quality of employee benefits during the 1980s and early 1990s, the overall quality of benefits offered to employees will rise by 1995.

-Off Topic

3)The proportional representation of heads of households in the labor market increased between the years 1988 and 1992.

-Proportional doesn't help us. As heads of households decrease, this number could the proportion could (and probably would) remain the same.

4)It has become progressively harder since the 1960s for households to subsist on a single earner’s pay, so an increasing proportion of the labor market are those who are not heads of households.

-Even though population may be decreasing, it is offset by the addition of another worker from the same household. Slight assumption that population will not decrease so much as to overshadow this.

5) By 1995 there will be far more people managing their own businesses than there have ever been previously.
