GWD6-Q21:
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 and having 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.
答案选C，怎么也想不通...请高人指点

题目说the most productive employees与普通员工不一样，他们每天工作10小时，只工作4天。 接着说该公司认为如果让所有员工的工作时间都像这些the most productive employees 一样，那么整体的productivity就会提高。
问削弱。
答案的方向应该是这个plan起不到公司所希望的效果，不会提高productivity.
A。无关
B。无关，是不是自愿的不是我们需要考虑的内容
D。该公司的员工的报酬是以什么决定的，与结论无关
E。take home无关

C选项，说这些most productive employees 的工作时间的安排，让他们有两个小时不受其他员工干扰的工作时间。没有人干扰所以效率高了，但是如果所有人都变成一个时间了，那么这个2小时的不受干扰的优势就没有了，那么就跟平常的工作时间安排没区别了，因此这个plan就起不到作用，所以削弱了结论。

嗯嗯，大致明白了，这题挺绕的感觉，谢谢啊，我发觉自己就是中文的逻辑都搞不清楚，我是跳跃思维.haha

这题其实最好的方法还是排除法，考试的时候我应该也不能直接判断出C选项，当然做过以后就觉得C选项很正确了~
所以排除法还是很重要的，明显无关的一律排除，剩下的一比较就出答案了：）

我对这道题也有问题···· 那全部人都实行10个小时的方案的时候就没有每天两个小时不被打扰吗？ 感觉并不充分阿
