Final answer:
Both the Lacasa system in traditional India and the estates system of pre-revolutionary France had a rigid class structure.
Step-by-step explanation:
Both the Lacasa system in traditional India and the estates system of pre-revolutionary France had a rigid class structure. In the Lacasa system, individuals were born into specific castes and had limited mobility, with upper castes holding more power and privilege than lower castes. Similarly, the estates system in France divided society into three distinct classes: the clergy, the nobility, and the commoners, with each class having different rights and privileges.
