Answer:
4. Sudra; they are lower caste but not Untouchables/ Dalit.
5. Vaishya; they are merchants
Step-by-step explanation:
The Hindu Caste system is one of the oldest and most deeply entrenched discriminatory systems in the world. It groups people into various castes which determines their social treatment.
4. This is a member of the Sudra caste. This is the lowest caste and it is believed that if they have good karma, they will move up to a higher caste when they reincarnate. Reference is made to the bottom of the barrel which refers to the Untouchables.
They are considered to be below the caste pyramid and are sometimes viewed as subhuman which leaves them vulnerable to abuse even in modern day India.
5. This is the Vaishya caste or the Merchant and Landowner caste. They are the third caste in the pyramid. They are craftsmen and merchants who sell to all castes thereby connecting them together.
