Final answer:
The statement about Dillon's Rule is false as it actually limits local government autonomy. The effect of the necessary and proper clause is to increase federal power, which makes the statement false. Claiming Antifederalists were really Federalists is false as they were distinct groups with differing views.
Step-by-step explanation:
The local union meeting is an essential aspect of a union's governmental activities, as it allows members to discuss issues, make decisions, and engage in governance. Regarding Dillon's Rule, this statement is false; Dillon's Rule actually restricts the freedom of local governments by stating that they can only engage in activities that are expressly authorized by state law.
The necessary and proper clause, often used to expand the power of the national government, has had the effect of increasing, not limiting, the power of the national government, making this statement false.
During the ratification debates, the Antifederalists and Federalists were opposed to each other; suggesting that Antifederalists were really Federalists is false. They had different views on the centralization of government power, including the necessary and proper clause and the creation of a strong national government.
The Constitutional Convention of 1787 aimed to address the weaknesses of the Articles of Confederation, thus the purpose of convening was indeed to revise the document; this statement is true.
