Read the lines from Langston Hughes’s poem "I, Too, Sing America."

Nobody’ll dare
Say to me,
“Eat in the kitchen,”

How did the lines support social change in the United States at the time the poem was written?

They demanded that African Americans be treated fairly.
They demonstrated that African Americans had a history of slavery.
They invited European Americans to eat at the kitchen table.
They persuaded European Americans to separate African Americans.
