Answer:
Step-by-step explanation:
2. Hinduism reinforced a social hierarchy called a caste system that made it hard for people to move outside. Buddhism rejected ritualism, scrifices, and dominace of the prestly class.
3. Ashoka changed the Mauryan empure through a centralized policy of dharma that favored peace and tolerance, and administered public works and social welfare.
4. Gupta empire successfully fought off the indo scythians, the kushans, persians and in their end days the hunas (hephthalite) even though they had faced lots of internal enemies within india itself, i think it was quite a remarkable achievement given the things turk barbarian armies did in the future. Romans couldnt even defeat the persians who themselves were badly slaughtered and got their king killed and their crown surrendered to the let alone fight hunnas/ hephthalite which invaded europe after them, so in my opinion gupta empire was stronger than roman empire.
