Personnel officer:  The exorbitant cost of our health-insurance benefits reflects the high dollar amount of medical expenses incurred by our employees.  Employees who are out of shape, as a group, have higher doctor bills and longer hospital stays than do their colleagues who are fit.  Therefore, since we must reduce our health-insurance costs, we should offer a rigorous fitness program of jogging and weight lifting to all employees, and require employees who are out of shape to participate.
 
The conclusion reached by the personnel officer depends on which of the following assumptions?

老师，这题我刚开始的做题过程和您录音中的思路完全一致。然后看选项了，发现C的内容和文中的内容几乎完全一致。同时也看了其他选项，看到了B，发现B写的更像佛且方向和C差不多，最后选了B。 后来review时候觉得在比较BC时候是不是BC的主体不一样。B是research没C的textbook好（符合原文） 还有一个问题。我1周后考试了，最近在尝试用PREP模考时候发现总是打不开试题（一直loading），已经尝试了不同电脑和操作系统，且从不同地方下载了该软件均告无效。因此，我打算放弃使用该模考系统而改用博森的GWD再配合prep破解版数学练习模考。问老师这时候我需要注意些什么，这样会对考试产生什么影响么。谢谢

Tiger sharks are common in the waters surrounding Tenare Island.  Usually tiger sharks feed on smaller sharks, but sometimes they have attacked tourists swimming and surfing at Tenare's beaches.  This has hurt Tenare's tourism industry, which is second only to its fishing industry in annual revenues.  In order to help the economy, therefore, the mayor of the island has proposed an ongoing program to kill any tiger sharks within a mile of the beaches.
 
Which of the following, if true, most strongly calls into question the likelihood that implementation of the mayor's proposal will have the desired consequence?
读完选项，依照字面意思，就扔了AB，看到 swimming and surfing 就选了E，然后就是问题也没看懂，相关度做的，D选项但是就觉得跟问题有点冲突，就没选
