Many students will assume an answer and provide it. The key is understanding the factors that go into the choice that person is making the objectives she has in making the trip and the constraints she faces. The purpose of the question is to realize that solutions are context based. You really can"t provide an answer that you can be sure is helpful until you ask some questions. Other modes of transportation can be introduced (train, plane, bus, roller skates). The solution should consider constraints (does she have the money for a plane ticket, time for the scenic route, a driver"s license if a drive is recommended). Many variations are possible, but the point is that no useful answer can be given without knowing more about the criteria she will apply in making the decision. They may want to know whether the university has above average library or computing facilities.
