The correct choice that analyzes the similar environmental and cultural impacts of the Aztec and Inca is:
3. They both altered their environment for farming and introduced language.
Analysis:
-
Environmental Impact: Both the Aztec and Inca civilizations made significant alterations to their environments to support agriculture. The Aztecs constructed chinampas, or floating gardens, to increase arable land in the swampy areas of Lake Texcoco. The Inca, on the other hand, developed terrace farming on the steep Andean mountainsides to maximize their agricultural output and prevent soil erosion. This manipulation of landscapes to enhance agricultural productivity illustrates their impact on their respective environments.
-
Cultural Impact: The introduction of language is also notable. While both cultures had their own distinct languages—Nahuatl for the Aztecs and Quechua for the Inca—they contributed to cultural exchanges, particularly through trade and conquests, leading to the spread of their languages and dialects across their regions. Additionally, both civilizations placed strong emphasis on agricultural practices, which were culturally significant and supported a wide range of societal functions.
The other choices contain inaccuracies or mix elements that are not specifically representative of both civilizations. For example, while they both worshipped various deities associated with the sun, the specifics about cocoa production (for the chocolate) primarily pertain to the Aztecs and not the Inca, who did not cultivate cacao in the same way.
