The Aztec civilization was described as being connected by which infrastructure?

• A. Roads
• B. Canals
• C. Railways
• D. Air routes

Answer: (A)

The key idea is how a large empire stays connected. The Aztecs built a robust road network, including raised causeways across Lake Texcoco that linked the capital, Tenochtitlan, to the surrounding mainland and other city-states. These roads made it feasible to move troops, traders, and messages quickly, helping to hold the empire together and integrate diverse regions.

Railways and air routes didn’t exist in this period, and while canals were used for transport and agriculture around the lake, they didn’t provide the broad, land-based connectivity that the roads and causeways did. So the road system is the best description of how the Aztec civilization was connected.
