GetThisDone
Companies that offer “employer sponsored insurance” (ESI) pay a portion of employees’ health care costs. In the manufacturing sector last year, companies that offered ESI had worker absentee rates 22% lower, on average, than those at companies that did not offer ESI.
If, on the basis of the evidence above, it is argued that ESI decreases worker absenteeism, which of the following, if true, would most seriously weaken that argument?
A. Results similar to those cited for the manufacturing sector have been found in other sectors of the economy where ESI is offered.
B. At companies that offer ESI, employees have access to preventative health care such as regular check-ups, routine laboratory tests, and nutrition counseling.
C. Because initiating an ESI plan requires a lot of paperwork for the company, employees, and the insurance provider, doing so is complex and time-consuming.
D. Many firms in the manufacturing sector have improved workplace safety and decreased the occurrence of on-the-job injuries in the last five years, and most of these companies introduced ESI at the same time.
E. In manufacturing firms where ESI is offered, the average productivity is 2% higher than it is in those firms where workers are not covered by an ESI plan.
OFFICIAL EXPLANATION
Last year, firms in the manufacturing sector that offered employees employer sponsored insurance (ESI) plans found that their worker absentee rates were significantly lower than at firms that did not offer ESI. What could have caused the decrease? The argument is made that the existence of the ESI plan caused the decrease in worker absenteeism, but that conclusion would be weakened if another cause were identified.
(A) Similar findings in other sectors of the economy strengthen rather than weaken the argument. (B) If workers have access to preventative health care as a result of the ESI plan, they might be healthier and would miss fewer days of work due to illness. This point supports the argument.
(C) The difficulty of initiating an ESI plan is irrelevant to a conclusion about what happens after the plan is established.
(D) CORRECT. If there are fewer on-the-job injuries, then workers will miss fewer days of work. This is an alternate explanation for the decrease in absenteeism, and thus weakens the argument that the decrease in absenteeism must have been due to the availability of ESI.
(E) The higher productivity of workers covered by ESI plans is consistent with the fact that they miss fewer days of work. This statement does not weaken the argument.
