Read the preamble to the constitution. we the people of the united states, in order to form a more perfect union, establish justice, insure domestic tranquility, provide for the common defence, promote the general welfare, and secure the blessings of liberty to ourselves and our posterity, do ordain and establish this constitution for the united states of america. according to the preamble, the phrase “a more perfect union” refers to 1.improving upon a previous attempt at creating a new union. 2.duplicating the original government system set up by the union. 3.creating a union with stronger ties between individual states. 4.building up the union with of foreign governments.

The correct answer is 1.improving upon a previous attempt at creating a new union.

The phrase “to form a more perfect Union” was used to refer to the shift to the Constitution from the Articles of Confederation. The Union would become more perfect because the Constitution would create a Federal Government that had enough power to act upon citizens directly. Before the government had a narrow and limited power and only could act on citizens only indirectly.

It also means the wish to form a stronger nation by creating a strong bond between the colonies.
