How was the Portuguese government in Brazil organized?

Portugal first divided Brazil into 15 hereditary captaincies, or land grants, administered by individual grantees. Because this system did not effectively govern the whole colony, the king appointed a governor-general to centralize authority and unify the grants. Thus, the correct choice is “A governor was appointed to centralize and unify the 15 hereditary land grants.”
