Ex Input:
Mahayana Buddhism received significant theoretical grounding from Nagarjuna (perhaps c. 150–250 CE), arguably the most influential scholar within the Mahayana tradition. Nagarjuna's primary contribution to Buddhist philosophy was the systematic exposition of the concept of śūnyatā, or "emptiness", widely attested in the Prajñāpāramitā sutras that emerged in his era. The concept of emptiness brings together other key Buddhist doctrines, particularly anatta and dependent origination, to refute the metaphysics of Sarvastivada and Sautrantika (extinct non-Mahayana schools). For Nagarjuna, it is not merely sentient beings that are empty of ātman; all phenomena (dharmas) are without any svabhava (literally "own-nature" or "self-nature"), and thus without any underlying essence; they are "empty" of being independent; thus the heterodox theories of svabhava circulating at the time were refuted on the basis of the doctrines of early Buddhism. Nagarjuna's school of thought is known as the Mādhyamaka. Some of the writings attributed to Nagarjuna made explicit references to Mahayana texts, but his philosophy was argued within the parameters set out by the agamas. He may have arrived at his positions from a desire to achieve a consistent exegesis of the Buddha's doctrine as recorded in the Canon. In the eyes of Nagarjuna the Buddha was not merely a forerunner, but the very founder of the Mādhyamaka system.

Ex Output:
Nagarjuna's main contribution was the exposition of the concept of what?


Ex Input:
Along with the desire for independence, tensions between Hindus and Muslims had also been developing over the years. The Muslims had always been a minority within the subcontinent, and the prospect of an exclusively Hindu government made them wary of independence; they were as inclined to mistrust Hindu rule as they were to resist the foreign Raj, although Gandhi called for unity between the two groups in an astonishing display of leadership. The British, extremely weakened by the Second World War, promised that they would leave and participated in the formation of an interim government. The British Indian territories gained independence in 1947, after being partitioned into the Union of India and Dominion of Pakistan. Following the controversial division of pre-partition Punjab and Bengal, rioting broke out between Sikhs, Hindus and Muslims in these provinces and spread to several other parts of India, leaving some 500,000 dead. Also, this period saw one of the largest mass migrations ever recorded in modern history, with a total of 12 million Hindus, Sikhs and Muslims moving between the newly created nations of India and Pakistan (which gained independence on 15 and 14 August 1947 respectively). In 1971, Bangladesh, formerly East Pakistan and East Bengal, seceded from Pakistan.

Ex Output:
What position did Muslims have in the Indian population?


Ex Input:
Oklahoma City was settled on April 22, 1889, when the area known as the "Unassigned Lands" was opened for settlement in an event known as "The Land Run". Some 10,000 homesteaders settled the area that would become the capital of Oklahoma. The town grew quickly; the population doubled between 1890 and 1900. Early leaders of the development of the city included Anton Classen, John Shartel, Henry Overholser and James W. Maney.

Ex Output:

What was the name of the land before being called Oklahoma City?
