2). black-owned businesses and separation from whites
3). agreement that blacks should accept an inferior social position
4). improvement of separate but equal facilities for both blacks and whites

2). Black-owned businesses and separation from whites.

Explanation:

Marcus Garvey was an African activist from Jamaica who would help lead a Pan-Africanism movement to fight for the rights of the Blacks in America. His objective is not merely within the confines of the American continent, but also to unify the Blacks all over the world.

He at first advocated for equality of the blacks and whites. But not just a normal equal treatment. He went further to emphasize the need for black-owned businesses that will ensure a stable flow of livelihood. He also then reiterate the need for blacks to be separate from the whites, for it is only then that they will have the full feeling of liberty to be themselves.

Thus, the correct answer is option 2.
