c) Traditional Water Management Systems of South India.
At a global level, only 2.7% of total water available is fresh water out of which almost 70% is concentrated in glaciers and icecaps (U.S. Geological Survey, 1993). This means that water is a limited resource and as fresh water is utilized for domestic, agricultural and industrial purposes, water demand is ever increasing with the increase in population and urban development.
As per the data collected by the world resource institute, more than 50% of India is under extreme water stress and more than 80% of the country is under extremely high overall water risk.
As per the composite water management index published by NITI Aayog, the total precipitation received by India is 4000 BCM out of which only 1869 BCM (46.7%) is considered as the water resource potential. Out of this, only 1123 BCM (28.1%) is the actual usable water resource.
India has a very diverse terrain which affects the climate of different regions resulting in distinctive summer, winter and monsoon seasons. Due to reasons such as dependency on monsoon, scarcity of water because of climate or lack of sources of water, many regions in India developed their own water management systems to conserve water.
Some of the most well-known water management systems can be seen in the State of Rajasthan which has a hot and dry climate and consists of the Thar desert which has very few sources of fresh water.

(b) Only two
Neo-Vaishnavism is a monotheistic religion that focuses on devotion rather than salvation. It was propagated by Srimanta Sankardeva in the 15th-16th century in Assam. It emphasized devotion to Lord Krishna, a central figure in Vaishnavism, and advocated for a more inclusive and egalitarian society. (Statement 1 is incorrect)
Vaishnavism is a religion that worships Lord Vishnu or one of his incarnations, like Lord Krishna or Lord Rama. Vaishnavites follow the Vaishnava tradition, which emphasizes devotion and surrender to Lord Vishnu or his incarnations.
Neo-Vaishnavism is against idol worship and does not acknowledge the Rādhā-Krishna cult. It focuses on devotion to Krishna through congregational listening and singing. The movement challenged the caste system and promoted social equality.

• The President can be removed from office by a process of impeachment for ‘violation of the Constitution’ (Article 61).
• The impeachment charges can be initiated by either House of Parliament – these charges should be signed by one-fourth members of the House (that framed the charges) and a 14 days’ notice should be given to the President – after the impeachment bill is passed by a majority of two-thirds of the total membership (strength) of that House, it is sent to the other House which should investigate the charges – the President has the right to appear and to be presented at such investigation – if the other House also sustains the charges and passes the impeachment bill by majority of two-thirds of the total membership, then the President stands removed from his office from the date on which the bill is so passed.

• Some of them are moral duties while others are civic duties.

(c) Nana Jagannath Shankarseth
The Maharashtra cabinet on Wednesday (March 13) decided to ask the Ministry of Railways to rename Mumbai Central station after Nana Jagannath Shankarseth. Mumbai Central, located in the heart of the city, is used by several important local and long-distance trains, including Rajdhani Expresses, daily.
Who was Nana Jagannath Shankarseth?
The social reformer, educationist, and philanthropist Nana Jagannath Shankarseth (February 10, 1803-July 31, 1865) is often described as the “architect” of Mumbai (then Bombay), who made extremely valuable contributions in terms of both ideas and money to multiple sectors, to lay a strong foundation for the city. Born in a wealthy Brahmin family in Murbad in Thane district, Shankarseth took the responsibility of running the family business at an early age after his father passed away in 1822. Shankarseth was greatly inspired by the legendary merchant and philanthropist Sir Jamsetjee Jeejeebhoy. As a social reformer and community leader, Shankarseth earned the goodwill of both Indians and the British. He became the first Indian to be nominated to the Legislative Council of Bombay.
