Problem: Given the question: Extract the answer to the question from the following context. Question: Who was Chief Justice before Warren? Context: Whittaker was unsuited for the role and soon retired. Stewart and Harlan were conservative Republicans, while Brennan was a Democrat who became a leading voice for liberalism. In selecting a Chief Justice, Eisenhower looked for an experienced jurist who could appeal to liberals in the party as well as law-and-order conservatives, noting privately that Warren "represents the kind of political, economic, and social thinking that I believe we need on the Supreme Court ... He has a national name for integrity, uprightness, and courage that, again, I believe we need on the Court". In the next few years Warren led the Court in a series of liberal decisions that revolutionized the role of the Court.

Problem: Given the question: Extract the answer to the question from the following context. Question: Where did the derogatory term for blacks originate from? Context: In the Colonial America of 1619, John Rolfe used negars in describing the slaves who were captured from West Africa and then shipped to the Virginia colony. Later American English spellings, neger and neggar, prevailed in a northern colony, New York under the Dutch, and in metropolitan Philadelphia's Moravian and Pennsylvania Dutch communities; the African Burial Ground in New York City originally was known by the Dutch name "Begraafplaats van de Neger" (Cemetery of the Negro); an early US occurrence of neger in Rhode Island, dates from 1625. Thomas Jefferson also used the term "black" in his Notes on the State of Virginia in allusion to the slave populations.

Problem: Given the question: Extract the answer to the question from the following context. Question: What did Buddha improve? Context: Meditation was an aspect of the practice of the yogis in the centuries preceding the Buddha. The Buddha built upon the yogis' concern with introspection and developed their meditative techniques, but rejected their theories of liberation. In Buddhism, mindfulness and clear awareness are to be developed at all times; in pre-Buddhist yogic practices there is no such injunction. A yogi in the Brahmanical tradition is not to practice while defecating, for example, while a Buddhist monastic should do so.
