It’s B

Well, the other choices were simply wrong :)

The correct answer is B. They built suspension bridges over rivers.

To find the answer to this question, you can start by researching the Inca civilization and their road system. The Inca Empire, which thrived in ancient Peru from the 13th to the 16th centuries, is known for its extensive and sophisticated road network. Here's how you can go about research to find the correct answer:

1. Begin by searching for information on the Inca road system. You can use search engines like Google or Bing. Look for reliable sources such as academic articles, books, or reputable websites.
2. Read about the construction methods and techniques employed by the Inca. Look for specific details related to the roads and bridges they built.
3. Pay attention to information about how the Inca dealt with various obstacles, such as rivers, along their road network.
4. Evaluate the various options provided in the question, considering the information you have gathered.

By following these steps, you would find that the Inca used suspension bridges (option B) to overcome rivers along their road system. These bridges were made using ropes woven from local materials, such as grass and fibers, and were often reinforced with wood or metal cables. This allowed them to create a network of roads that connected different regions of their empire, even across challenging terrains.
