1. Gunadhya is an ancient Indian author who is credited with writing the Brihatkatha, a large collection of tales that is considered one of the greatest works of Sanskrit literature.
2. The Brihatkatha is a vast and complex work that tells the stories of many different characters and cultures. It is said to have been written in the Paisācī language, a Prakrit dialect that was spoken in western India at the time.

A nation is a group of people with a common language, history, culture, and geographic territory. A state is characterized by four essential elements- territory, population, sovereignty, and a government.

The people are generally emotionally, attached to their place of birth. But millions of people leave their places of birth and residence. There could be variety of reasons. These reasons can be put into two broad categories:
o The Push Factors: These cause the people to leave their place of residence or origin; and
The Pull Factors: These attract the people from different places.
In India, the people migrate from the rural to the urban areas, mainly due to poverty, high population pressure on the land, lack of basic infrastructural facilities like health care, education, etc. Apart from these factors, natural disasters, such as, floods, droughts, cyclonic storms, earthquakes, tsunamis, wars and local conflicts also give extra push to migrate.
On the other hand, there are ‘Pull Factors’, which attract the people from the rural areas to the cities. The most important Pull Factor for majority of the rural migrants to the urban areas is better opportunities, availability of regular work and relatively higher wages. Better opportunities for education, better health facilities and sources of entertainment, etc., are also quite important Pull Factors.

Explanation:
 Priority Sector means those sectors which the Government of India and Reserve Bank of India consider as important for the development of the basic needs of the country and are to be given priority over other sectors. The banks are mandated to encourage the growth of such sectors with adequate and timely credit.
 All Indian banks have to follow the compulsory target of priority sector lending (PSL). The priority sector in India is at present the sectors— agriculture, small and medium enterprises (SMEs), road and water transport, retail trade, small business, small housing loans (not more than Rs. 10 lakhs), software industries, self-help groups (SHGs), agro-processing, education, small and marginal farmers, artisans, distressed urban poor and indebted non-institutional debtors besides the SCs, STs and other weaker sections of society.
 In 2007, the RBI included five minorities— Buddhists, Christians, Muslims, Parsis and Sikhs under the PSL. In its new guidelines of March 2015, the RBI added ‘medium enterprise, sanitation and renewable energy’ under it.

Explanation:
 A tropical cyclone is a rapidly rotating storm originating over tropical oceans from where it draws the
 energy to develop. The origin, development, intensity, and track of tropical cyclones are linked to ocean
 conditions. Tropical cyclones derive their source of energy, heat and moisture from the warm waters of
 the tropical ocean. So, statement 1 is correct.
 A Cyclone needs the following favourable conditions to form and intensify.
• Large surface areas with temperatures more than 27° C.
• Presence of Coriolis force
• Small variations in vertical wind speed
• A pre-existing weak low-pressure area or low cyclonic circulation.
• Upper divergence above the sea level system. So, statement 2 is correct.
 A Landfall is the intersection of the centre of a tropical cyclone with a coastline. Typically, in strong
 tropical cyclones, landfall occurs when the eye of the cyclone moves over land. Landfall is often
 accompanied by strong winds, lashing rain and rising sea waves that could endanger people and cause
 damage to property. So, statement 3 is correct.
