Question

how did julius caesar provide employment for the urban poor?
by forcing them to become gladiators
by starting major building projects
by launching a police force
by giving them positions in the government

Explanation:

Julius Caesar started major building projects. These projects required labor, which provided employment opportunities for the urban poor. Forcing them to be gladiators was not a common employment - providing method in a positive sense. Launching a police force was more about maintaining order than employment for the urban poor. And giving positions in the government was not a widespread way to employ the urban poor compared to large - scale construction.

Answer:

by starting major building projects
