Answer 1

It allowed the military to move people and supplies further.

Step-by-step explanation:

The building of the roads in the Roman empire secured them during the ancient times. Besides being used for trading, it also allowed the military to move people and supplies further. The roads were primarily built in a way that the Roman military would strategically win from their enemies. It allowed them to respond swiftly to intruders and also helped ease the distribution of supplies in the empire.
