Q:I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "In 1901, the Federation of Australia was the process by which the six separate British self-governing colonies of New South Wales, Queensland, South Australia, Tasmania, Victoria and Western Australia formed one nation. They kept the systems of government that they had developed as separate colonies but also would have a federal government that was responsible for matters concerning the whole nation. When the Constitution of Australia came into force, the colonies collectively became states of the Commonwealth of Australia."?
A:
Where state systems of government left in place or discarded during the formation of the Commonwealth of Australia early in the 20th Century?
