-preamble to the us constitution
which function or role of government is not expressed within the preamble?
a) preserve freedom
b) maintain a peaceful nation
c) protect the bill of rights
d) defend against external enemies

The correct answer is C. To protect the Bill of Rights is not a function of government expressed within the Preamble.

Explanation:

The Preamble to the Constitution of the United States could never have made any reference to the fulfillment of the rights set forth in the Bill of Rights for a basic reason: the Preamble was created in 1787 along with the Constitution, during the Philadelphia Convention. The Bill of Rights, in turn, was approved in 1791 in response to the fears of the Anti-Federalists about the scope of citizen rights in the recently ratified Constitution.

Therefore, due to this temporary issue, the Preamble could never make any mention of the Bill of Rights.
