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.

The 2 more Hrs for the productive employees allowed them free from disturbing by others. Taking the propasal may lead to lowering the efficiency of the productive employees.

是自愿去的还是被安排去的，跟结论没有关系。题目关心的是，是不是效率提高了？
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.
说了十小时工作制的一个特点，效率的提高在于不被其他人打扰的那两个小时。如果实行新方案，不受打扰的环境就没有了。削弱了新方案能提高效率的可能性。
