its 1/a, not 3/c

Yes, you are correct. The Aztecs adapted to their environment mainly by using terraces and irrigation to farm.

To arrive at this answer, you need to understand how the Aztecs lived and interacted with their environment. Here's how you can approach finding the answer:

1) Familiarize yourself with the Aztec civilization: Start by gaining a basic understanding of who the Aztecs were and where they lived. The Aztecs were a Mesoamerican civilization that thrived in central Mexico from the 14th to the 16th century. They built their capital city, Tenochtitlan, on an island in Lake Texcoco.

2) Evaluate the given options: Consider each option provided and analyze whether it aligns with the Aztec way of life and their adaptation to the environment.

- Option 1: The use of terraces and irrigation aligns with the Aztec civilization's methods of farming. Since they lived in an area surrounded by lakes and marshes, they created chinampas, which were artificial islands made of mud and vegetation. These floating gardens on shallow lakes were used for farming and relied on irrigation and terracing techniques to support agricultural production.

- Option 2: The Aztecs were not nomadic hunter-gatherers. They were an agricultural civilization that relied on farming as their primary means of sustenance.

- Option 3: While the Aztecs engaged in trade, it wasn't always peaceful. They had an extensive trade network and engaged in both peaceful and conflict-based interactions with neighboring civilizations.

- Option 4: The Aztecs did not primarily settle along the coasts for fishing. They settled in the central region of Mexico, particularly around Lake Texcoco.

3) Analyze the information: Based on the evaluation of each option, the use of terraces and irrigation (Option 1) is the most accurate answer. This is because it aligns with the Aztec civilization's agricultural practices and adaptation to their environment.

So in summary, the Aztecs adapted to their environment mainly by using terraces and irrigation to farm.
