Answer:
patriarchal
Explanation:
Authority means that someone has a power over you. That power can be seen through giving orders, proclaiming laws to be obeyed, being in charge of the property, money, food etc.
Traditional authority means that it's been going on for a long period of time and that the people are kinda used to it.
In sociology, one of the examples of the traditional authority is patriarchy. It is a system where men hold power in their hands.
In this case, Susan's father is heading the household, which means that she experiences a patriarchal style of authority.
