Read the following passage and answer the questions below:
"In the history of nation-building only the Soviet experiment bears comparison with the Indian. There too, a sense of unity had to be forged between many diverse ethnic groups, religious, linguistic communities and social classes. The scale - geographic as well as demographic - was comparably massive. The raw material the state had to work with was equally unpropitious: a people divided by faith and driven by debt and disease." - Ramachandra Guha
