A county is planning to expand its train service. In studying the current service, the county planner looked at which train stations are along or not along various train lines.

The Venn diagram shows this information for three of the lines. (a) Select all the train lines that do not have a stop at Kent. (b) How many stations are along the Blue Line or the Purple Line (or both)? (c) Which stations are along neither the Blue Line nor the Green Line nor the Purple Line? Choose all that apply.
