Researchers have found that, allowing for variations attributable to the size of a company’s workforce and to the company’s business sector, companies that have low staff turnover tend to have greater labor productivity than companies with higher turnover. Since high staff turnover negatively affects workers’ sense of community and identification with company goals, clearly these adverse effects on staff attitudes are the cause of the decline in productivity as turnover increases.The conclusion of the argument is the following:
these adverse effects on staff attitudes are the cause of the decline in productivity as turnover increasesThe support for the conclusion is the following:
high staff turnover negatively affects workers’ sense of community and identification with company goalsSo, the author has gone from the fact that high turnover has adverse effects on staff attitudes to the conclusion that the cause of "the decline in productivity as turnover increases" is "adverse effects on staff attitudes."
Which of the following, if true, most seriously weakens the argument?This is a Weaken question, and the correct answer will somehow weaken the support for or cast doubt on the conclusion.
A. Laying off workers and, especially, hiring new ones both require continuing staff to spend time on activities that do not immediately contribute to output.This choice casts doubt on the conclusion.
After all, if this choice is true, then we have an alternative cause for the decline in productivity as turnover increases.
If this choice is true, then it may not be that adverse effects on staff attitudes cause the decline, and it may instead be that the decline occurs because laying off workers and hiring new ones require staff to spend time on activities that do not immediately contribute to output.
Keep.
B. The introduction of technology intended to increase labor productivity can, by changing the skills needed to accomplish a task, entail an increase in staff turnover.We can often weaken an argument by presenting an alternative cause for an effect. So, this choice could seem to weaken the argument because it presents a cause for the effect "an increase in staff turnover."
At the same time, this choice doesn't weaken this argument in that way because the effect the conclusion is about is not "an increase in staff turnover." It's "the decline in productivity as turnover increases."
Since this choice doesn't present an alternative cause for the decline in productivity, it doesn't weaken the argument by presenting an alternative cause.
Alternatively, this choice could seem to weaken the argument because this choice describes a situation that contrasts with the pattern that the argument is about.
The argument is about a general pattern: higher turnover is associated with lower productivity.
In contrast, this choice describes a situation in which higher turnover is associated with higher productivity, or at least with the process of achieving higher productivity.
At the same time, this choice does not weaken the argument because all this choice is saying is that there can be an exception to the general pattern when a certain type of process, "introduction of technology intended to increase labor productivity," occurs.
The argument's conclusion is that the reason for the general pattern is that adverse effects on staff attitudes cause of a decline in productivity as turnover increases.
The fact that there can be an exception to the general pattern does not mean that the argument's conclusion about the cause of that general pattern is not correct.
Eliminate.
C. In proportion to the size of the workforce, staff turnover tends to be somewhat higher in large companies than in relatively small companies.This choice is an irrelevant comparison choice.
After all, the fact that staff turnover tends to be somewhat higher in large companies than in relatively small companies doesn't clearly indicate anything about the cause of the decline in productivity as turnover increases.
Eliminate.
D. Even when staff turnover has been low, staff morale can suffer when changes in the business environment adversely affect the company’s financial prospects.This choice masquerades as a weakener by weakening the case for a conclusion other than the conclusion of this argument.
It weakens the case for the conclusion that staff morale declines only because of turnover issues.
That's not the conclusion we need to cast doubt on.
Eliminate.
E. Workers’ sense of community and degree of identification with company goals both tend to be stronger in relatively small companies than in large companies.This choice is an irrelevant comparison choice.
After all, the fact that workers’ sense of community and degree of identification with company goals both tend to be stronger in relatively small companies than in large companies doesn't clearly indicate anything about the cause of the decline in productivity as turnover increases.
Eliminate.
