Final answer:
Quaestors were early Roman officials responsible for overseeing the financial matters of the state, managing the treasury, and ensuring funds were properly utilized.
Step-by-step explanation:
At the beginning of the Roman Empire, when only two Quaestors were required, their primary job was to oversee financial matters. These early Roman officials were in charge of the state treasury and finances, a crucial responsibility given the extensive military campaigns and public works typical of the empire's expansive activities. They played a significant role in the fiscal management of the state, ensuring that public funds were accounted for and properly disbursed for various aspects of governance, such as paying soldiers, funding state ceremonies, and purchasing supplies for public projects.
