premise: A television programming director is scheduling a three-hour block of programs beginning at 1 P.M. The programs that are to fill this time block include an hour-long program called Generations and four half-hour programs: Roamin', Sundown, Terry, and Waterloo. The programs will be shown one after the other, each program shown exactly once. The schedule must meet the following constraints: Generations starts on the hour rather than the half hour. Terry starts on the half hour rather than the hour. Roamin' is shown earlier than Sundown. If Waterloo is shown earlier than Terry, it is shown immediately before Terry. Which one of the following could be the order in which the programs are shown, from earliest to latest?
hypothesis: Waterloo, Roamin', Sundown, Terry, Generations
