Question

read this quotation from the freedom charter, written in 1955.
we, the people of south africa, black and white together—equals, countrymen and brothers—adopt this freedom charter. and we pledge ourselves to strive together, sparing neither strength nor courage, until the democratic changes here set out have been won.
what was the purpose of this document?
to call for the end of colonial rule
to found the african national congress
to demand equality for all south african citizens
to create a plan of government for south africa

Explanation:

The quotation emphasizes black and white South Africans as equals and pledges to win democratic changes. The Freedom Charter was a key document advocating for equal rights regardless of race. The ANC was founded before 1955, the document was not focused on ending colonial rule specifically (apartheid was the system then) nor was it a full government plan.

Answer:

to demand equality for all South African citizens
