Answers with Explanation
1. (b) Rigveda is considered oldest among the four Vedas. It contains 2028 Suktas. Out of these, 250 suktas are dedicated to Indra. Indra holds a special place among heavenly gods. He is known to be the god of storm and thunder. He is also known as Purandar because he destroyed the Puras. Then comes Varun. Either he is equivalent to Indra or comes second after Indra. Agni is also an important deity of Rigvedic gods. 200 suktas are dedicated to him. He is intermediary between gods and humans as he accepts the sacrifices made by humans and delivers them to the gods. Rudra is also an important deity. He is the god of wind. Vishnu is also mentioned in Rigveda but he was not very important in that era.
2. (a) Shilppadikaram is an important epic of Sangam literature. It was written by Ilango Vadigal, grand son of great Chola king, Karikal. It is a very realistic book. It contains the sad story of the son of a rich businessman of Puhar or Kaveri Pattnam, Kovalan and his beautiful but unfortunate wife Kannagi. It is through this epic, we get to know that Raja Gajabahu I, emperor of Sri Lanka was present at the inaugural function of a temple of goddess of virginity, Kannagi which was organized by Sher Naresh Shenguttuvan. Sri Lankan emperor Gajabahu I ruled in the latter part of 2nd century. Vishnu Swamin was a saint who founded the Shuddhadvaitavad.
3. (d) Shankardev was the person who popularized Vaishnavism in Kamrup (Assam). He lived from 1449 to 1568. His message was centered on the devotion of Vishnu or his incarnation, Krishna. Monoethism was the gist of his preaching. The community founded by him was known as Ek Sharan sampraday. Shankardev was opposed to both idol worship and karm kand. He was the only Krishna follower vaishnava saint who was opposed to worshiping Krishna in the form of idol. Since he was the greatest Vaishnava saint of Assam, he was also known as Chaitanya of Assam. Nimbarkacharya founded Dvaitvaad. Ramanand was the first saint of North India of the Bhakti era.

4. (a) Keeping the importance of water in mind, Maurya emperor, Chandragupta Maurya built a lake. Pushyagupta, the provincial governor of Chandragupta Maurya built the famous Sudarshan lake near Girnar in Gujarat.

5. (d) In the question, date on Chalukya is mentioned 556 Shaka Samvat. According to Jain literature, Shakas defeated the descendants of Vikramaditya (57 BC) in his 135th year of rule and captured his kingdom. They started a samvat in the honour of this victory, which is known as Shaka Samvat. Thus the first year of Shaka Samvat is calculated to 135 -57= 78. Some scholars are not in favour of associating the shaka samvat with any one ruler but most of them accept that ruler of Kushana dynasty, Kanishka is its promoter. Putting the date in question into this equation, the Chalukya date become 78 + 556 AD= 634 AD.
