American progress, john gast, 1872 this painting best relates what social philosophy? a) gilded age b) great awakening c) manifest destiny d) women's suffrage

Your answer would be C). Manifest Destiny.

The reason why this would be your answer is because in 1872, the Manifest Destiny was a belief that all the settlers would spread across North America, and the painting, Manifest Destiny, by John Gast, portrays the belief of the settlers expanding across what is now the United States.

the main reason that the constitution did not proclaim all men to be free and equal is because of the issue of slavery.
