6. The students at a crowded university have trouble waking up before 10 a.m., and most work jobs after 3 p.m. As a result, there is a great deal of demand for classes between 10 a.m. and 3 p.m., and classes before and after those hours are rarely full. To make matters worse, the university has a limited amount of classroom space and faculty. This means that not every student can take classes during the most desirable times. Building new classrooms and hiring more faculty are not options. The administration asks for your advice about the best way to solve the problem of demand during the peak class hours. What advice would you give?
