Solution:

The "PURA" (Provision of Urban Amenities to Rural Areas) model was conceptualized by Dr. A.P.J. Abdul Kalam, the 11th President of India. He proposed this model to bridge the rural-urban divide by providing urban amenities in rural areas, focusing on:

1. Physical connectivity (roads, bridges, etc.)
2. Electronic connectivity (internet, communication, etc.)
3. Knowledge connectivity (education, skill development, etc.)

The goal of PURA is to create clusters of economically vibrant villages, improving the quality of life and economic opportunities for rural communities.
