Read the following passage and answer the questions -

The campaign for decentralization of authority has a long past. As history shows, sustained attempts were made to decentralize authority in India since the 1880s with the acceptance of Rippon resolution of 1882. One of the most clearly - stated justifications for Panchayati Raj Institutions (PRIs) was given by the report of the Ashok Mehta Committee. Another categorical statement regarding strengthening of local self - government was made by the report of the 1986 L. M. Singhvi Committee, Revitalisation of PRIS for Democracy and Development. What was strongly argued became a reality with the adoption of the 73rd Amendment Act in 1992, which not only constitutionalised local self government in India but also gave the long overdue constitutional recognition to PRIS. The legislative origins of the 73rd constitutional Amendment Act can be traced back to the constitutional 64th Amendment Bill, which was introduced in the Parliament in 1989. 73rd constitutional Amendment Act of 1992 introduced a three - tier structure of rural local level - gram Panchayats at the lowest level, panchayat samiti at the intermediate level and zilla parishad at the highest level.
