Universities should require every student to take a variety of courses outside the student's field of study.
The following memorandum is from the business manager of Happy Pancake Houserestaurants.
""Recently, butter has been replaced by margarine in Happy Pancake House Trestaurants throughout the southwestern United States. This change, however, has had Llittle impact on our customers. In fact, only about 2 percent of customers have complained, indicating that an average of 98 people out of 100 are happy with the change. Furthermore, many servers have reported that a number of customers who ask for butter do not complain when they are given margarine instead. Clearly, either Gthese customers do not distinguish butter from margarine or they use the term 'butter' to refer to either butter or margarine."
