The correct answer is:
1. The Federalist essays
4. The promise to create a Bill of Rights.
Explanation:
The Federalist essays or papers were written by James Madison, Alexander Hamilton and John Jay in the late 1780s. Those essays were sent under the pseudonym "Publius" to newspapers to influence the voters in favor of ratification of the Constitution of the United States arguing that it would help to give power to the federal government so it could act on behalf of the nation's interest and that it would preserve the Union, the essays also discussed general problems of politics, and were published all together as a book in 1788. The Federalist papers influenced doubtful states to ratify the Constitution.
Anti federalists thought the Constitution gave too much power to the federal government, and that it needed a Bill of Rights to make sure the federal government wouldn't abuse its power, so during the ratification process Massachusetts, Virginia and New York pressured for the creation of the Bill of Rights, and James Madison (federalist) agreed to write the Bill of Rights to ensure ratification of the United States Constitution.
