Answer: Voting structure in the estates general.
Step-by-step explanation:
States General was the representational assembly of the three estates. The clergy and nobility were privileged minorities, while the Third Estate represented the rest of the people.
During the last meeting of the Estates General, at the beginning of the French Revolution (1789), the Third Estate worried that the two privileged estates would overcome the general public in its effort to establish a reform.
Therefore, the revolutionary National Assembly was created, putting an end to the representation by social classes.
