Answer: B
 The Prayaga Prashasti (also known as the Allahabad Pillar Inscription) composed in
Sanskrit by Harishena, the court poet of Samudragupta, arguably the most powerful of the Gupta rulers.
 The Pandya chief Senguttuvan

Answer: D
 Many chiefs and kings, including the Satavahanas who ruled over parts of western and central India (c. second century BCE-second century CE) and the Shakas, a people of Central Asian origin who established kingdoms in the north-western and western parts of the subcontinent, derived revenues from long-distance trade. Their social origins were often obscure, but, as we will see in the case of the Satavahanas (Chapter 3), once they acquired power they attempted to claim social status in a variety of ways.
 The founder of the Satavahana dynasty was Simuka. He and his successors established their authority from the mouth of the Krishna to the entire Deccan plateau. According to the Puranas, the Satavahana king killed the last Kanva ruler of Magadha and presumably took possession of his kingdom.
 The earliest of the Satavahana kings to receive wide recognition was Satakarni I, and this was due to his policy of military expansion in all directions. He is the Lord of the west who defied Kharavela of Kalinga and against whom the latter campaigned. His conquests took him north of the Narmada into eastern Malva, which at the time was being threatened by the Shakas and the Greeks.
 Satakarni I gained control of the region of Sanchi, and an inscription there refers to him as Rajan Shri Satakarni. His next move was in the southerly direction and on conquering the Godavari valley hefelt entitled to call himself Lord of the Southern Regions’ (Dakshina – pathapati).
 The description of Satakarni I as (‘Dakshina -pathapati) in the Nanaghat inscription of Nayanika proves that the Satavahana dominion was not confined to western Deccan alone, but included other areas of the Deccan and beyond Satakarni I performed two Asvamedha sacrifices and one Rajasuya sacrifice.
 Satvahan Administrative system was feudal. They had divided their empire among a number of feudal chiefs who managed the land revenue system and looked after the administration.

Answer: A

 The Indus valley civilisation is also called the Harappan culture. Archaeologists use
the term “culture” for a group of objects, distinctive in style, that are usually found
together within a specific geographical area and period of time. In the case of the
Harappan culture, these distinctive objects include seals, beads, weights, stone blades and even baked bricks. These objects were found from areas as far apart as Afghanistan, Jammu, Baluchistan (Pakistan) and Gujarat . Named after Harappa, the first site where this unique culture was discovered the civilisation is dated between c. 2600 and 1900 BCE. There were earlier and later cultures, often
called Early Harappan and Late Harappan, in the same area. The Harappan civilisation is sometimes called the Mature Harappan culture to distinguish it from these cultures.
 Most Harappan sites are located in semi-arid lands, where irrigation was probably
required for agriculture. Traces of canals have been found at the Harappan site of
Shortughai in Afghanistan, but not in Punjab or Sind.
