According to the passage, the constitution of Australia does not state any of the following EXCEPT
The Governor-General of Australia will exercise the British monarch's power in their absence.
The passage describes the formation of Australia as a federation and provides some details about its governance. The constitution states that the Governor-General of Australia exercises the British monarch's power in their absence, which is the correct statement. - Option (A) is incorrect because it implies Australia's six states will have their own governments, which was true, but it was not emphasized as an exception in the passage. - Option (B) is incorrect because it implies a direct control of Australia by the monarch of Britain, which is not stated in the constitution. - Option (C) is also incorrect as the passage does not claim Queen Victoria will always be the Head of State. Thus, Option (D) is the only accurate statement, as it refers to the powers held by the Governor-General in the absence of the British monarch.
The question asks which statement the passage's description of the Constitution actually supports, treating the other three as things the passage does not state. Checking each option against what the passage explicitly describes about the Constitution separates them.
Since A, B, and C describe things the passage's account does not state, while D matches what it explicitly describes, D is the exception.
Hence, the correct answer is Option D.
