An overwhelming proportion of the most productive employees at SaleCo's regional 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?
Every employee of SaleCo who has been there for at least a year is entitled to three weeks of vacation each year and must be paid his or her regular salary for that time off.
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.
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.
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.
Some of SaleCo's employees have indicated to company officials that they would quit if not allowed to work the same hours as the company's most productive employees.
我就想知道,B难道不是切断了相关性吗?这些效率高的人按照一天10小时,一周4天的工作时间完全是被老板要求的,他们即便不按照这个要求也可能达到这个效率。这不就切断了相关性——一天10小时,一周4天→效率高。
我觉得你有点想过头了。你怎么就可以确定他们没按照这个要求也有可能达到这个效率?排除B的理由我觉得是,首先他们在这样的安排下效率高是已经既定的事实,无论是不是他们自愿的,如果老板看到这种安排自然也会要求其他的员工按照这种时间规定,以此期望他们达到这种效率。因此B选项还有可能有点加强了结论。。。
而且也并没有切断相关性,你切断相关性的前提是”没有被要求这样工作“。但原文没有提到任何关于这个的,而是你自己脑补出来的。。。
