Read the following passage and answer the questions. In January 1957, the Government of India appointed a committee to examine the working of the community development programme (1952) and the National Extension Service (1953) and to suggest measures for their better working. The chairman of this committee was Balwant Rai Mehta. The committee submitted its report in November 1957 and recommended the establishment of the scheme of democratic decentralisation, which ultimately came to be known as Panchayati Raj. The specific recommendations made by it included the establishment of a three-tier Panchayat Raj system: Gram Panchayat at the village level, Panchayat Samiti at the block level, and Zila Parishad at the district level.
