The correct response is: The U.S. Constitution requires approval by Congress, while the Florida Constitution can be amended by voter referendum.
To elaborate, the U.S. Constitution can be amended either by a two-thirds majority in both the House of Representatives and the Senate or by a convention called for by two-thirds of state legislatures. In contrast, the Florida Constitution allows for amendments through various methods, including voter referenda, which can be initiated by a citizen's petition or by the state legislature.
