[求助] argument范文里的一段话

关於112. The following appeared in a memo to the Saluda town council from the town’s business manager.
       

“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% and thereby achieve a balanced town budget.”
        

范文里的其中一段说:

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.

想请问the cost of building a well-equipped exercise facility 和 negate the savings realized on the group health insurance 有什麽关系? 不胜感激~~
