Question: 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.
