In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Example Input: Question: In what year was the house the Vogtei went to after the Lenzburg family established? Passage:The first mention of modern Hägglingen is in 1036 when Count Ulrich von Lenzburg granted the church and farm of Hekelingen to Beromünster. In the acknowledgments of Emperor Henry III in 1045, the village of Hackelingen was mentioned. Frederick I Barbarossa acknowledged the grants to the village in 1173. The Vogtei (bailiwick) went from the Lenzburg family to the Kyburgs and then in 1273 to the Lords of Hallwyl. The high court rights were exercised by the Habsburgs until the Swiss conquered the Aargau in 1415. It was not until 1425 that Hägglingen, which was claimed by Lucerne, came under the authority of the entire Confederacy. It was first assigned to the district court of Wohlenschwil before it became an independent municipality from 1435-1712.

Example Input: Question: How many years were there between the death of Charlemagne and the first award of the Charlemagne Prize? Passage:The Charlemagne Prize (; full name originally Internationaler Karlspreis der Stadt Aachen, International Charlemagne Prize of the City of Aachen, since 1988 Internationaler Karlspreis zu Aachen, International Charlemagne Prize of Aachen) is a prize awarded for work done in the service of European unification. It has been awarded annually since 1950 by the German city of Aachen. It commemorates Charlemagne, ruler of the Frankish Empire and founder of what became the Holy Roman Empire, who resided and is buried in Aachen. Traditionally the award is given to the recipient on Ascension Day in a ceremony in the town hall of Aachen. In April 2008, the organisers of the Charlemagne Prize and the European Parliament jointly created a new European Charlemagne Youth Prize, which recognises contributions by young people towards the process of European integration. Patrons of the foundation are King Philippe of Belgium, King Felipe VI of Spain, and Henri, the Grand Duke of Luxembourg.

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.
