Question: Passage: In September 1913 in Göttingen, Weyl married Friederike Bertha Helene Joseph (March 30, 1893 - September 5, 1948) who went by the name Helene (nickname "Hella"). Helene was a daughter of Dr. Bruno Joseph (December 13, 1861 - June 10, 1934), a physician who held the position of Sanitätsrat in Ribnitz-Damgarten, Germany. Helene was a philosopher (she was a disciple of phenomenologist Edmund Husserl) and also a translator of Spanish literature into German and English (especially the works of Spanish philosopher José Ortega y Gasset).  It was through Helenes close connection with Husserl that Hermann became familiar with (and greatly influenced by) Husserls thought. Hermann and Helene had two sons, Fritz Joachim Weyl (February 19, 1915 - July 20, 1977) and Michael Weyl (September 15, 1917 - March 19, 2011), both of whom were born in Zürich, Switzerland. Helene died in Princeton, New Jersey on September 5, 1948. A memorial service in her honor was held in Princeton on September 9, 1948. Speakers at her memorial service included her son Fritz Joachim Weyl and mathematicians Oswald Veblen and Richard Courant. In 1950 Hermann married sculptress Ellen Bär (née Lohnstein) (April 17, 1902 - July 14, 1988), who was the widow of professor Richard Josef Bär (September 11, 1892 - December 15, 1940) of Zürich. 
Question: How many years older was Ellen Bär when she died than Helene? 
Answer type: Number 

Answer: 31.


Question: Passage: In the Governorate of Estonia, Estonians called for freedom of the press and assembly, for universal suffrage, and for national autonomy. On 29 October , the Russian army opened fire in a meeting on a street market in Tallinn in which about 8 000-10 000 people participated, killing 94 and injuring over 200. The October Manifesto was supported in Estonia and the Estonian flag was displayed publicly for the first time. Jaan Tõnisson used the new political freedoms to widen the rights of Estonians by establishing the first Estonian political party - National Progress Party. Another, more radical political organisation, the Estonian Social Democratic Workers' Union was founded as well. The moderate supporters of Tõnisson and the more radical supporters of Jaan Teemant could not agree about how to continue with the revolution, and only agreed that both wanted to limit the rights of Baltic Germans and to end Russification. The radical views were publicly welcomed and in December 1905, martial law was declared in Tallinn. A total of 160 manors were looted, resulting in ca. 400 workers and peasants being killed by the army. Estonian gains from the revolution were minimal, but the tense stability that prevailed between 1905 and 1917 allowed Estonians to advance the aspiration of national statehood. 
Question: How many years did the tense stability last? 
Answer type: Number 

Answer: 12.


Question: Passage: A large number of minor nobles also joined the Crusade and before long, according to Arnold von Lübeck in his Arnoldi Chronica Slavorum, a powerful military host of 60,000, including 7,000 German knights, was on its way. A contemporary chronicler gave a lower estimate of 4,000 knights and an unknown amount of infantry. German historian Claudia Naumann suggested in 1994 that the Crusade had 16,000 men, including 3,000 knights.Bretislaus III, Duke of Bohemia had agreed to join the Crusade at the Diet in Worms on December 1195, and planned to do so, until he fell ill and died on 15 or 19 June 1197. In March 1197 Henry proceeded to the Kingdom of Sicily. The crusaders embarked for Acre, while the emperor first had to suppress an armed revolt in Catania. A force of 3,000 Saxon and Rhenish troops in 44 ships under Count Palatine Henry V and Archbishop Hartwig of Bremen sailed from northern Germany and arrived in Messina in August, where they merged with the emperor's troops and sailed to the Eastern Mediterranean. Still in Sicily, out for hunting near Fiumedinisi in August, Emperor Henry fell ill with chills, possibly from malaria. He died on September 28 before he could set sail for the Holy Land. 
Question: How many years passed between 1994 and 1197?
