Task: Question Generation
Input (English): Passage: After graduating from the Academy in 1930 Solti was appointed to the staff of the Hungarian State Opera. He found that working as a répétiteur, coaching singers in their roles and playing at rehearsals, was a more fruitful preparation than Unger's classes for his intended career as a conductor. In 1932 he went to Karlsruhe in Germany as assistant to Josef Krips, but within a year, Krips, anticipating the imminent rise to power of Hitler and the Nazis, insisted that Solti should go home to Budapest, where at that time Jews were not in danger. Other Jewish and anti-Nazi musicians also left Germany for Budapest. Among other musical exiles with whom Solti worked there were Otto Klemperer, Fritz Busch, and Kleiber. Before Austria fell under Nazi control, Solti was assistant to Arturo Toscanini at the 1937 Salzburg Festival:
Toscanini was the first great musical impression in my life. Before I heard him live in 1936, I had never heard a great opera conductor, not in Budapest, and it was like a lightning flash. I heard his Falstaff in 1936 and the impact was unbelievable. It was the first time I heard an ensemble singing absolutely precisely. It was fantastic. Then I never expected to meet Toscanini. It was a chance in a million. I had a letter of recommendation from the director of the Budapest Opera to the president of the Salzburg Festival. He received me and said: "Do you know Magic Flute, because we have an influenza epidemic and two of our repetiteurs are ill? Could you play this afternoon for the stage rehearsals?".
Output (English): What is the last name of the person who went to Karlsruhe in Germany as assistant to Krips?
