Read the following text carefully : The Labour Force Participation Rate (LFPR) measures the percentage of the population either employed or actively seeking employment in a nation. In India, the labour force grew by 99.2 million persons between 2000 - 2019. The labour force grew from 396.3 million to 495.5 million. During 2012 - 2019, the labour force grew without a matching increase in employment, leading to higher unemployment. The gender disparity in India's labour market is notable with women's LFPR at 32.8% in 2022, significantly lower than men's LFPR at 77.2%. This is a major reason for India's overall low LFPR, which is lower than the global average of 47.3%. During 2000 - 2019, rural LFPR declined by 14.1%, compared to a 3.5% decline in urban areas. This trend reversed between 2019 - 2022, with rural LFPR increasing by 6% (especially among rural women) and urban LFPR by 2.1%. These shifts suggest that fluctuations occur in women's labour market participation, particularly in rural areas. This significantly affected the overall LFPR. Women join the workforce during economic hardships and move out when conditions improve. On the basis of the given text and common understanding, answer the following questions : (a) Define unemployment. (b) Write the meaning of Labour Force Participation Rate (LFPR). (c) Comment upon the gender disparities in rural and urban Labour Force Participation Rate (LFPR) during 2000 - 2019.
