Abstract
This software asks a series of multiple choice questions in the form of drills on four time periods (the emergence of the nation, from isolation to imperialism, from World War I to the cold war, the nuclear age). Wrong answers call for second tries, but help is available the third time the answer is given. Answers may be linked to children's games (race car, ski slalom, lunar landing, shooting gallery).
