The correct answer is: They built suspension bridges over rivers.
The Incas developed their road system by laying roads in the cities and densely populated areas, rather than in the less densely populated deserts. They did not use mortar to hold the stones together, nor did they build suspension bridges over rivers. They also did not mix copper and stone together to make the blocks.
To understand how the Incas developed their road system, we can look into historical records and archaeological evidence. One primary factor in the construction of their roadways was the absence of mortar. The Incas perfected the art of fitting stones together so tightly that no mortar was needed to hold them in place. This technique is known as "ashlar masonry." By meticulously shaping the stones to fit precisely, they created a strong and enduring road infrastructure.
Regarding suspension bridges, while the Incas did build some impressive rope bridges, they were primarily used for crossing rivers rather than being an integral part of their road system.
The claim that the Incas mixed copper and stone together to make the blocks is not supported by historical evidence. The Incas predominantly used a variety of locally available stones, such as granite, andesite, and basalt, in their construction projects.
The statement about laying roads only in cities and not in less densely populated areas like deserts is incorrect. The Inca road system, known as the Qhapaq Ñan, was a vast network that linked various regions of the Inca Empire, including cities, rural areas, and even deserts.
In summary, the Inca road system was constructed through precision stone fitting rather than the use of mortar. They did build suspension bridges for river crossings, but the primary road construction was focused on connecting different parts of their empire, including both urban and rural areas. Copper and stone mixing and the exclusion of deserts from the road system are not accurate explanations.
