1. Many major corporations require their employees to wear conventional business attire, though they sometimes allow employees to wear casual attire on Fridays. Employees typically accomplish more work on such Fridays, and so their productivity is higher during those weeks than during weeks in which they must wear conventional attire every day. However, employees in corporations that allow casual attire every day are typically less productive than employees of corporations that require conventional attire every day.
The statements above, if true, can best be used as evidence supporting which of the following hypotheses?
(A) People's productivity at work is sometimes improved by variations in their work conditions.
(B) When people have more control over their work environments, they are more receptive to requests to change their work habits.
(C) Less work is generally performed on Fridays than is performed on other business days.
(D) People tend to work more productively when fewer restrictions are imposed on them.
(E) People are generally unable to change their work habits unless they are offered strong incentives to do so.

A. Government regulations concerning testing requirements for novel drugs have become steadily more stringent.

C. Many pharmaceutical companies have entered into collaborative projects with leading universities, while others have hired faculty members away from universities by offering very generous salaries.
D. The number of cases in which one company’s researchers duplicated work done by another company’s researchers has steadily grown.
