Explanation:
Achievements of the Maya, Aztec, and Inca Civilizations
The Maya, Aztec, and Inca civilizations are renowned for their contributions to human development, and several achievements stand out among them:
- Iron weapons: None of these civilizations utilized iron weapons. The Maya and Aztecs primarily used weapons made of stone, wood, and obsidian, while the Inca had primarily bronze and stone tools.
- Terraced farming: This was an important agricultural technique used notably by the Inca. They developed extensive terraces on the steep Andean slopes which allowed for efficient farming by maximizing arable land and controlling water runoff.
- Calendar: All three civilizations had sophisticated calendar systems. The Maya, in particular, developed a complex calendar system that included both a 260-day ritual calendar and a 365-day solar calendar, which were used for agricultural and ceremonial purposes.
Given these points, the correct achievements from the options provided would be Terraced farming and Calendar but since we must choose one, Calendar is often celebrated as a significant achievement across these civilizations.
