In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it. Your job is to determine which sentence(s) from the passage can be used to search for further information needed to answer the question.

Example Input: Question: Of the Wagner operas that Vogl had roles in, which was written first? Passage:He played the role of Loge in Richard Wagner's Das Rheingold at Munich Court Opera on September 22, 1869, with his wife, Therese Vogl, playing the role of Wellgunde. He also played the role of Siegmund in Wagner's Die Walküre, also at Munich, on June 26, 1870. Therese Vogl played the role of Siegmund's sister and lover Sieglinde in the same performance. His Munich debut was as Max in Weber's Der Freischütz. He sang at Bayreuth, Berlin, London and the Metropolitan Opera in New York City. At Bayreuth, he played the role of Loge in the first complete Ring cycle on August 13, 1876. His performance in the role caused fellow singer Lilli Lehmann to comment that he was born for the part and that his Loge had never been equalled. His debut at the Metropolitan Opera was in the title role of Lohengrin on January 1, 1890, and he also sang Loge, Siegmund, the title role of Tannhäuser, Tristan in Tristan und Isolde, and Siegfried in both Siegfried and Götterdämmerung at the Met. Heinrich Vogl was also the first performer to play the roles of Loge and Siegfried in London, which he did in the first Ring cycle in London at Her Majesty's Theatre, with Anton Seidl conducting and his wife playing the role of Brünnhilde.

Example Output: He played the role of Loge in Richard Wagner's Das Rheingold at Munich Court Opera on September 22, 1869, with his wife, Therese Vogl, playing the role of Wellgunde

Example Input: Question: How old was Erwin Ackerknecht when he was excluded from the SAPD in 1937? Passage:Inside the SAPD, the first part of 1937 saw an intensification of differences over attitudes to a possible political party of the united left or a Popular front, and more precisely over the party's approach to the Soviet Union. The differences led to Peter Blachstein's exclusion from the SAPD. Others excluded at the same time included his political mentor and Erwin Ackerknecht: the three became the focus of a short-lived political grouping known as "Neuer Weg" ("New Way"). Blachstein was also affected more directly by the intense political tensions radiating out from Moscow, based on Stalin's suspicions - not entirely unfounded - that there might be comrades in the Soviet Union and further west in Europe who favoured an alternative Soviet leader. The POUM, of which Blachstein was a member, backed a broadly Trotskyite vision for a communist future and its members therefore became targets for Soviet agents. In June 1937 Blachstein was arrested in Barcelona by communist secret police and accused of spying for Franco and working for the Gestapo. With approximately 100 other foreign detainees he was taken to a large garage which had been adapted for use as an ad hoc prison. Because of the appalling hygiene he soon fell ill with Tuberculosis, as a result of which he was transferred to a sanatorium controlled by anarchist comrades. Helped by Spanish friends, in January 1938 he succeeded in escaping back to France.

Example Output: Others excluded at the same time included his political mentor and Erwin Ackerknecht: the three became the focus of a short-lived political grouping known as "Neuer Weg" ("New Way")

Example Input: Question: What year did the adventure-novelist begin his position as secretary to Lord Milner? Passage:Curtis was born at Coddington, Herefordshire in 1872, the youngest of the four children of an Anglican rector. He was educated at Haileybury College and then at New College, Oxford, where he read law. He fought in the Second Boer War with the City Imperial Volunteers and served as secretary to Lord Milner (a position that had also been held by adventure-novelist John Buchan), during which time he dedicated himself to working for a united self-governing South Africa. Following Milner's death in 1925, he became the second leader of Milner's Kindergarten until his own death in 1955. His experience led him to conceptualize his version of a Federal World Government, which became his life work. In pursuit of this goal, he founded (1910) the quarterly Round Table. He was appointed (1912) Beit lecturer in colonial history at the University of Oxford, and a Fellow of All Souls College.

Example Output:
