The more frequently employees take time to exercise during working hours each week, the fewer sick days they take.  Even employees who exercise only once a week during working hours take less sick time than those who do not exercise.  Therefore, if companies started fitness programs, the absentee rate in those companies would decrease significantly.

Which of the following, if true, most seriously weakens the argument above?

(A) Employees who exercise during working hours occasionally fall asleep for short periods of time after they exercise.（根缺席没有关系，倒是跟工作效率和工作表现有关）

(B) Employees who are frequently absent are the least likely to cooperate with or to join a corporate fitness program.

(C) Employees who exercise only once a week in their company's fitness program usually also exercise after work.（根工作无关，，即无关选项）

(D) Employees who exercise in their company's fitness program use their working time no more productively than those who do not exercise.

(E) Employees who exercise during working hours take slightly longer lunch breaks than employees who do not exercise.
        （反而会迟到，跟原文的结论相悖）

为什么选B呢， 感觉B有点是支持或者是假设的味道啊

原文要提高出勤率。那么是针对谁来提高呢？当然是针对出勤率低的员工。

那么出勤率低的这些员工又不参加健身，那么当然健身就无法提高出勤率了。

另外D/E都是无关选项，没有涉及都出勤率的问题。E说午休时间长，并不能推出就会迟到，这是你自己的推理。
就算会迟到，那也不见得可以得出出勤率低，这又是你自己的推理。

做逻辑切忌自己推论。

 多谢LS的

再提一个问题，如果B改成 Employees who are frequently absent are the most likely to cooperate with or to join a corporate fitness program. 

这个时候是加强还是削弱呢，？

去掉 least，当然就是support，再加一个most就更加支持了。
