Loans from Co-operatives
Besides banks, the other major source of cheap credit in rural areas are the co-operative societies. Members of a co-operative pool their resources for co-operation in certain areas. There are several types of co-operatives possible such as farmers co-operatives, weavers co-operatives, industrial workers co-operatives etc. Krishak Co-operative functions in a village not very far away from Sonpur. It has 2300 farmers as members. It accepts deposits from its members. With these deposits as collateral, the co-operative has obtained a large loan from the bank.

The Need for Political Parties
As we have seen, large societies need representative democracy. As societies became large and complex, they also needed some agency to gather different views on various issues and to present these to the government. They needed some ways, to bring various representatives together so that a responsible government could be formed. They needed a mechanism to support or restrain the government, make policies, justify or oppose them. Political parties fulfil these needs that every representative government has. We can say that parties are a necessary condition for a democracy.- CBSE Class X - 2025

The Independence Day Pledge, 26 January 1930
“We believe that it is the inalienable right of the Indian people, as of any other people, to have freedom and to enjoy the fruits of their toil and have the necessities of life, so that they may have full opportunities of growth. We also believe that if any government deprives people of these rights and oppresses them, the people have a further right to alter it or abolish it. The British Government in India has not only deprived the Indian
people of their freedom but based itself on the exploitation of the masses, and has ruined India economically, politically, culturally and spiritually. We believe, therefore, that India must sever the British connection and attain Purna Swaraj or Complete Independence.”- CBSE Class X - 2025
