Example Input: Question: When did the country where Pimu hospital is located change names? Passage:He went out with the Baptist Missionary Society as a missionary doctor in 1935 to Pimu hospital, DRC in what was then the Belgian Congo. He was at Pimu Hospital, Province of Équateur until 1946, most of the time as the only doctor there (TLM, The Leprosy Mission started working there in 1944). He remained in the Belgian Congo in World War II. In 1930 there had been 30 Protestant missionaries in the Congo, but by 1939 Dr. Price was one of only five left. Although Belgium had been invaded by the Nazis, the Belgian government in exile in London continued to control the Congo and its valuable resources. In 1944 he published a paper on the grammar of the Ngombe language (one of the languages of Equateur Province) and thereafter contributed to the updating of the British and Foreign Bible Society's 1930 Ngombe New Testament, which was republished in 1956. In 1947 he was sent on a sabbatical to the UK by the Baptist Missionary Society to specialise as an orthopaedic surgeon (FRCS Ed. 1947). Returning to the Congo he went first to Sona Bata mission (part of the American Foreign Baptist Mission Society (A.F.B.M.S.), now American Baptist International Ministries), which already had a medical aide training school, and where he was tasked with helping to build Kimpese hospital. Kimpese hospital was set up by the protestant missions in the Congo as an interdenominational training hospital for medical auxiliaries. A Protestant hospital at Kimpese had first been mooted in 1923 (there had been an Evangelical training Institute there since 1909), but was strongly resisted by the Roman Catholic Church.. Before the war, the Belgian colonial government had refused to subsidise any Protestant educational enterprise, even the training of medical aides (the sole exception was the BMS medical aides training school at Yakusu). After the war this policy was reversed by the Socialist governments of Achille Van Acker and Protestant establishments were subsidised on the same basis as Catholic ones. As a result the Protestant IME (Institut Medical Evangelique) Kimpese could be opened. He was at IME Kimpese as an orthopaedic surgeon 1947-1956. He was succeeded in this post, as he had been at Pimu by Dr David Hedley Wilson, later the first President of the Royal college of Emergency Medicine. IME Kimpese "became rapidly known throughout the lower Congo river and beyond for the high standard of its nursing school and hospital". During this time, he developed an interest in the rehabilitation of leprosy patients.
