Input: Consider Input: Passage: Pinza sang once again under the baton of Toscanini in 1935, this time with the New York Philharmonic Orchestra, as the bass soloist in performances of Beethoven's Missa Solemnis. One of these performances was broadcast by CBS and preserved on transcription discs; this recording has been issued on LPs and CDs. He also sang in Toscanini's February 6, 1938, NBC Symphony Orchestra's broadcast performance of Beethoven's Ninth Symphony. These performances both took place in Carnegie Hall. In March 1942, Pinza was arrested at his home and unjustly detained 3 months on Ellis Island with hundreds of other Italian-Americans who were suspected of supporting the Axis. The incident was extremely traumatic for Pinza, and he suffered from severe depression for years afterward. In October 1947, he performed the role of Mephistopheles in Guonod's Faust opposite his daughter, soprano Claudia Pinza Bozzolla, as Marguerite at the San Francisco Opera.
Link Information: none Question: How many pieces had Beethoven composed before the one Pinza performed in 1935?

Output: Answer: none

Input: Consider Input: Passage: In 1889 de Mores joined La Ligue antisemitique de France (Antisemitic League of France) founded by Edouard Drumont. After more verbal attacks on Jews, he went to Algeria to strengthen the French hold there and stop British advances into the interior of Africa. He used anti-Semitic rhetoric to his advantage in Algeria, giving speeches claiming that French and African Jews and the British were conspiring to conquer the entire Sahara Desert. With the British in a difficult position in the Sudan after the death of General Charles George Gordon in the siege of Khartoum, de Mores planned a trip there to meet with the Mahdi, a powerful Muslim leader who was intent on undermining British hegemony in the region. He traveled to North Africa, selected Arabic men in Tunis to escort him, and set out his caravan towards Kebili.
Link Information: The failure to rescue General Gordon's force in Sudan was a major blow to Prime Minister Gladstone's popularity. Queen Victoria sent him a telegram of rebuke which found its way into the press. Victoria's telegram was not coded as usual which suggests she wanted it to appear in the press. Critics said Gladstone had neglected military affairs and had not acted promptly enough to save the besieged Gordon. Critics inverted his acronym, "G.O.M." (for "Grand Old Man"), to "M.O.G." (for "Murderer of Gordon"). Question: Who was held responsible for Charles George Gordon's death?
Output: Answer: Prime Minister Gladstone
