关于GWD 9 Q28里D选项的疑问

21. An overwhelming proportion of the most productive employees at SaleCo’s regional offices work not eight hours a day, five days a week, as do other SaleCo employees, but rather ten hours a day, four days a week, with Friday off.Noting this phenomenon, SaleCo’s president plans to increase overall productivity by keeping the offices closed on Fridays andhaving all employees work the same schedule—ten hours a day, four days a week.



Which of the following, if true, provides the most reason to doubt that the president’s plan, if implemented, will achieve its stated purpose?



A. Typically, a SaleCo employee’s least productive hours in the workplace are the early afternoon hours.

B. None of the employees who work four days a week had volunteered to work that schedule, but all were assigned to it by their supervisors.

C. Working ten hours a day has allowed the most productive employees to work two hours alone each day in their respective offices relatively undisturbed by fellow employees.

D. Employees at SaleCo are compensated not on the basis of how many hours a week they work but on the basis of how productive they are during the hours they are at work.
E. Those SaleCo employees who have a four-day workweek do not take any of their office work to do at home on Fridays.


答案是C，没有问题，但是关于D选项，有一点疑问

题目的结论是为了提高工作效率，要采用每天10小时，一周4天的工作方法。换句话说，就是10/4的方法可以提高生产率。

C选项weaken了，没有问题

但是D选项，说公司付酬劳是以生产率为准，而不易工作时间为准。那么不就说明老总的plan没有用了吗？因为你如何换工作时间制度也没用，酬劳决定了生产率。那么不就weaken了结论吗？

请有想法的童鞋指导，欢迎拍砖，我知道我的推理应该有断链，但是卡住了出不来~先谢过了

Because we don't know whether the new plan will increase the production.
