Final answer:
16th century Latin America and 19th century Africa both experienced colonization and exploitation by European powers, which involved the settlement, conquest, and resource extraction in these regions.
Step-by-step explanation:
The similarity between 16th century Latin America and 19th century Africa is that both regions experienced colonization and exploitation by European powers. During the 16th century, European nations such as Spain and Portugal began to colonize lands in the Americas, which included large parts of Latin America. The indigenous populations were subjected to conquest, and their resources were exploited. Similarly, in the 19th century, various European powers, through colonization efforts, dominated Africa. Regions like West and Central Africa particularly saw the rise of exploitation through the transatlantic slave trade, while Southern Africa experienced European settlement beginning with the Dutch establishment of Cape Colony.
