In the "Address to the Niagara Movement," DuBois makes the point that with continued effort, it is possible for Black Americans to attain equal rights and opportunities. Which two answers provide reasoning to support this point?

"Cannot the nation that has absorbed ten million foreigners into its political life without catastrophe absorb ten million Negro Americans into that same political life at less cost than their unjust and illegal exclusion will involve?"

"The Slave is rising in his might, the yellow millions are tasting liberty, the black Africans are writhing toward the light, and everywhere the laborer, with ballot in his hand, is voting open the gates of opportunity and peace."

"And we shall win. The past promised it, the present foretells it."

"Our enemies, triumphant for the present, are fighting the stars in their courses."
