题目信息

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.

正确答案： 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.

题目中说因为老板发现了公司里那些最有效率的员工的工作时间（1周上4天，每天10小时）和其他员工（每周上5天，每天8小时）不一样，所以老板认为将所有员工的工作时间都调整到1周4天，每天10小时是可以增加整体公司的效率的。问削弱。

那这题目中的逻辑链是，老板认为员工的工作效率是由1周上4天，每天10小时这样的工作时间安排而提高的。问削弱，自然就是找出其他可以导致工作效提高的原因。对应C选项中的最有效率的那些人之所以比别的员工有效率，是因为他们利用了每天多出来的2个小时可以专心做工作，在这两个多余的小时里他们不会被其他正常下班已经走了的同事所打扰，效率自然就高了。也就是点出了工作效率高不是因为每天多出的两个小时，而是因为这两个小时里所受的干扰会比正常工作时间要少。如果大家都变成每天工作10个小时，一周工作四天的话，人和人之间就会相互打扰，这多出的2个小时就没有了特殊性，与正常8小时的上班时间没有
