Example Input: Question: How many leaders run the priestly class? Passage:Traditional African religions like the Serer religion (A ƭat Roog) are adhered to by devout worshippers of Roog – the supreme deity in Serer religion. The Serer ethnic group who adhere to the tenets of Serer religion (including those Senegalese who syncretize) honour the Serer pangool and have ancient rituals and festivals devoted to them. The religious affairs of Serer religion devotees are usually headed by the Saltigue (the Serer priestly class) which in ancient times was the preoccupation of the Serer lamanic class. Some of these religious festivals or ceremonies include the Ndut (rite of passage), Xooy (divination festival once a year in Fatick), and the Raan festival. Senegalese hold several ancient beliefs, such as small efforts of 'thanks' or demands, such as protection from water. They also place great importance on the Baobab tree, which is known as the "House of the Spirits." The baobab tree along with other sacred trees figure prominently in the Serer creation narrative. Among the Jola people, some religious festivals include the Samay, Kumpo and the Niasse.

Example Input: Question: How many years had Gary Tallon been playing professionally by the year Boulding turned professional? Passage:Boulding maintained his links with football and trained with Doncaster Rovers, and in 1998 he joined non-league Hallam near his home in Sheffield. His form at Hallam attracted the interest of a number of league clubs, and Boulding was offered a trial by Mansfield Town. He was given a contract by the Division Three side and turned professional in 1999, which brought an end to his tennis career. He made his debut with Mansfield in a League Cup game against Nottingham Forest on 11 August 1999 as a late substitute for Gary Tallon, before his first league game came three days later against Cheltenham Town. He had to wait until his 12th game as a professional to register his first goal when he scored in a 2–1 victory over Shrewsbury Town on 23 October. He eventually finished his first season with six goals with Mansfield coming 17th but 17 points above Carlisle United, the only side to be relegated out of The Football League.

Example Input: Question: On what continent was Kilekwa born? Passage:Kilekwa was born in Zambia, in a Bissa village, in the Mbisa tribe, near Lake Bangweulu. He was born "Chilekwa"; Ki-, he says in his autobiography, "is a Swahili prefix". He was enslaved in the 1870s as a boy in what he called "the Maviti wars" (the term may point to "any brigand rather than to a specific ethnic group"). His mother was unable to pay his ransom — eight yards of calico cloth—and he was taken to the coast, headed for the Persian Gulf. However, the ship of his enslavers was stopped by the Royal Navy; HMS Osprey took them to Muscat. The group spent a month or so there, but then Kilekwa and another boy, Mambwala, were volunteered to serve on the Osprey and become seamen. They did odd jobs while the Osprey, looking for slave dhows, sailed throughout the Gulf and up the Euphrates to Basra (in present-day Iraq). One day, while most of the sailors were on shore in Bushehr, Persia, slavers tried to kidnap them but were prevented. They traveled as far as India and went sightseeing in Bombay. When the Osprey was to return to England, the two were transferred to HMS Bacchante; they were in Bombay again for the Golden Jubilee of Queen Victoria in 1887.
