Explanation:
Defending such a vast territory is a challenging task because it requires a significant amount of resources, including a large and well-trained military, communication and supply lines, and efficient coordination. The vastness of the Roman empire would have made it difficult to monitor and protect all of its borders, providing opportunities for invaders to penetrate and attack different regions. Additionally, the empire's size made it challenging to respond quickly to threats, especially with limited means of transportation and communication available during ancient times.
