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 Walkure, 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 Freischutz. 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 Tannhauser, Tristan in Tristan und Isolde, and Siegfried in both Siegfried and Gotterdammerung 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 Brunnhilde.

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: Of the grasses that the essex skipper eats, which is the longest? Passage:Eggs are laid in strings on the stems of grasses where they remain over the winter. The Essex skipper's favoured foodplant is cock's-foot (Dactylis glomerata), and it rarely uses the small skipper's favoured foodplant Yorkshire fog. Essex skippers' other foods include creeping soft grass (Holcus mollis), couch grass (Elymus repens), timothy-grass (Phleum pratense), meadow foxtail (Alopecurus pratensis), false brome (Brachypodium sylvaticum) and tor-grass (Brachypodium pinnatum). This skipper's caterpillars emerge in the spring and feed until June before forming shelters from leaves tied with silk at the base of the foodplant to pupate. Adults fly from July through August. Like most skippers, they are fairly strictly diurnal, though individuals are very rarely encountered during the night.

Example Output:
