Answer:
1. Citizen farmers could not look after their farms and lost their land and livelihood after returning from war.
Step-by-step explanation:
Every Roman citizen was required to participate in the Roman army, this was considered a duty of citizenship. During the heyday of the Roman Empire, calls for the army were seasonal, but as the years went by and the size of the cities grew, the Roman army needed to make calls at shorter intervals. Wealthy citizens had certain perks and even received wages, but lower-class citizens (such as farmers) were required to spend long periods with the army.
The problem is that lower-class citizens had to leave their homes and jobs to join the army. The downside to this is that citizen farmers could not take care of their farms because they spent too much time away from home and lost their land and livelihoods after returning from the war.
