The correct answers for why the Inca Empire was defeated are:
- Disease ravaged the Inca Empire.
- Pizarro took Atahualpa hostage and then had him executed.
The other options do not accurately reflect historical events related to the defeat of the Inca Empire:
- The Inca did not learn from the Aztecs’ mistakes in a way that proved beneficial for them; instead, they were caught off guard by the Spanish tactics and the unforeseen consequences of European colonization.
- Pizarro did not sail down the east coast of South America to Argentina; he primarily conquered the Inca Empire in Peru.
- The Spanish did not send messages of peace and friendship in a genuine manner; rather, they engaged in military conquests and manipulation.
