What were the two primary construction materials used for supporting the Aztec buildings?

The correct choice highlights the use of pyrons and lava rock as primary construction materials for Aztec buildings. The Aztecs, like many other Mesoamerican cultures, utilized the abundant volcanic materials available in their region. Lava rock, in particular, was readily accessible and durable, making it an excellent choice for building structures such as temples, pyramids, and other significant architectural works.

Pyrons, which refers to a type of stone material, indicates the Aztecs' resourcefulness in using local geological resources for construction purposes. Their architectural achievements, including the Great Pyramid of Tenochtitlan and various temples, exemplify their ability to transform these materials into impressive and robust structures that have stood the test of time.

The other options do not accurately reflect the primary materials the Aztecs used. While wood and stone were used in various cultures, the Aztecs primarily relied on volcanic materials given their geographic context. Adobe and clay were commonly used for other Mesoamerican cultures, but in the context of the Aztecs, they favored more durable materials. Similarly, bricks and mortar do not represent the specific practices of Aztec construction, as their techniques and materials were distinctively linked to the volcanic landscape of their region.
