20. AA. Research indicating people who exercise are more healthy that those who don’t, so the company decide to build a gym to reduce the health insurance coverage, and expect the cost will be reduce by50%
No.106 or 108. "Research indicates that those who exercise regularly are hospitalized less than half as often as those who don’t exercise. By providing a well-equipped gym for Saluda’s municipal employees, we should be able to reduce the cost of our group health insurance coverage by approximately 50 percent and thereby achieve a balanced town budget."
Argument: 根据一份research的调查显示，exercise regularly people hospitalized 的几率比 do not exercise 的people 小一半。因此
1. There is no causal relationship between the development of the employees' health and the provision of a well-equipped gym.
2. Therefore, the reduction of the cost of group health insurance coverage expected by the author is not guaranteed.
3. Even if the provision of the gym can cause a reduction of the cost, no one can rely on it to achieve a balanced town budget since the health incidents occur very randomly.
Third, the manager assumes that there is a direct relation between the hospitalization rate for employees and the cost of their group health insurance such that a reduction in the hospitalization rate will result in a corresponding reduction in the cost of insurance. While this may turn out to be true, the manager has failed to offer any evidence for this claim.
Finally, the manager assumes that the cost of building a well-equipped exercise facility will not negate the savings realized on the group health insurance. Until evidence has been provided to show that this is not the case, the manager’s plan is unacceptable.
In conclusion, the business manager’s proposal to provide an exercise facility as a means of balancing Saluda’s budget is not convincing. To strengthen the argument, evidence would have to be provided for each of the assumptions listed in the previous analysis.
