Most of the people in Latin America were descended from these three groups. Which three?

Native Americans

Europeans

Australians

Asians

Americans

Africans

The major ancestry is native American - some people have only this ancestry still. Many people have also a European ancestry, from Spain and other countries. The third group are Africans - who were brought as slaves, especially to the Caribbean and Brazil.

The option of Americans is confusing - this word is used for all inhabitants of America regardless of ancestry
