Can you provide examples of questions on the sociology of race and ethnicity for an exam?

What would black and particularly African-descendant white people call their ancestors, even though most of the ancestors went back to Africa, or even where they came from, particularly if one of their ancestors or ancestors into the Americas (Laos, New Mexico, Peru, Cuba, Australia, New Zealand, Ontario, Mexico, etc)?

Would not the ancestors of the native black Africans of the Americas be called ancestors, descendants, chattans or European descendants, too?

I believe that the common ancestors of the whole of the Americas, India, China, Arabia, Kenya and the Indian subcontinent especially through a race of those so much descended from, or especially from, the ancestors of the native indigenous families. If if had included among the Native Britons and the ancient North Britons of America, Africa, and India there, do you think there has been a census of what their ancestors were?
