Final answer:
The correct answer is D. The Aztec and Inca Empires were geographically isolated.
Step-by-step explanation:
The correct answer is D. The Aztec and Inca Empires were geographically isolated.
The Spanish conquistadors were successful in conquering the Aztec and Inca Empires for several reasons, but geographic isolation was not one of them. The Aztec and Inca Empires were both located in regions with well-established trade routes and connections to other cultures. This made it easier for the Spanish to find allies and access resources during their conquests.
An example of the Spanish finding unexpected allies is the Totonacs who greeted the Spanish as liberators. Additionally, the inadvertent introduction of diseases, such as smallpox, played a significant role in weakening the native populations and facilitating the Spanish conquest.
