Answer:
The machines accepted bribes in return for favors.
Step-by-step explanation:
A political machine was a system of unequal personal relationships in political apparatuses between influential people and their "clients", that is, those people who benefited from their relationship with politicians in exchange for bribes and other illegitimate practices. Thus, these types of organizations functioned unofficially through the assignment of positions through clientelism, behind-the-scenes control and lasting political ties within the framework of representative democracy. Some machines had a "boss", who was a renowned politician, and all machines have a group of people who depend on the protection of the machine in the form of contracts or jobs.
