the economic security of the inca empire was based on

intensive maize farming

enviromental diversity

extensive trade with the aztec empire

ruthless massacres of enemy peoples

my answer is enviromental diversity
is that correct

Nope.

then it has to be maize farming

You're probably right.

Apologies for any confusion, but the economic security of the Inca Empire was not primarily based on environmental diversity. Rather, it was a combination of intensive maize farming and extensive trade routes established by the Inca Empire. So, the correct answer is not environmental diversity.

The Inca Empire was situated in a region of the world featuring a variety of climates and ecological zones. This diversity allowed the Incas to cultivate different crops at different altitudes, taking advantage of the varying environmental conditions. While this environmental diversity was an aspect of Inca agriculture, it was not the core foundation of their economic security.

The primary source of economic stability for the Inca Empire was the intensive farming of maize, a staple crop. Maize farming was undertaken throughout the empire's territories and played a crucial role in sustaining the population. The Incas implemented advanced agricultural techniques, such as terrace farming and irrigation systems, enabling them to maximize productivity and store surplus crops for times of scarcity.

In addition to agriculture, extensive trade networks contributed significantly to the economic resources of the Inca Empire. The Incas established a vast road network, known as the Inca road system, which facilitated trade and communication across their empire. This network allowed for the exchange of goods, including textiles, pottery, metals, and agricultural products, with other regions, such as the Aztec Empire. Thus, trade was an important pillar of the Inca economy.

The Inca Empire did engage in military campaigns and conquests, which occasionally involved ruthless massacres of enemy peoples. However, these actions were not the foundation of their economic security.

In summary, while environmental diversity was a factor in the Inca Empire's agricultural practices, the economic security was primarily based on intensive maize farming and extensive trade routes.
