The king maintained control through a rigid class structure. Which statements accurately describe an aspect of the class structure? Choose all answers that are correct. Creoles were of Spanish descent but born in America and therefore seldom held government positions. Mestizos were of mixed race, Spanish and Indian, and were generally poor, if free. Peninsulares were native-born Spaniards who held all the important positions in the colonies. Milanos were on the lowest rung on the social ladder and were little more than slaves.
