ORAL COMPREHENSION - THE CASTE SYSTEM
The caste system in India corresponds to a system of social stratification existing for centuries and mainly rooted in the Hindu tradition. People are divided into five groups / castes. It was originally based on a division of labor (people belonged to a caste according to their occupation).
When someone is born into a class, it is impossible to change it. It is also impossible to intermarry. The main problem is that this system prevents people of the lower castes from climbing the social ladder.
