This task involves creating answers to complex questions, from a given passage. Answering these questions, typically involve understanding multiple sentences. Make sure that your answer has the same type as the "answer type" mentioned in input. The provided "answer type" can be of any of the following types: "span", "date", "number". A "span" answer is a continuous phrase taken directly from the passage or question. You can directly copy-paste the text from the passage or the question for span type answers. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words. A "number" type answer can include a digit specifying an actual value. For "date" type answers, use DD MM YYYY format e.g. 11 Jan 1992. If full date is not available in the passage you can write partial date such as 1992 or Jan 1992. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words.

Example Input: 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?

Example Input: Passage: Before Hunyadi could assemble his forces, the army of Mehmed II  arrived at Belgrade. The siege began on July 4, 1456. Szilágyi could rely on a force of only 5,000-7,000 men in the castle. Mehmed set up his siege on the neck of the headland and started heavily bombarding the city's walls on June 29. He arrayed his men in three sections: The Rumelian corps had the majority of his 300 cannons, while his fleet of 200 river war vessels had the rest of them. The Rumelians were arrayed on the right wing and the Anatolian corps were arrayed on the left. In the middle were the personal guards of the Sultan, the Janissaries, and his command post. The Anatolian corps and the Janissaries were both heavy infantry troops. Mehmed posted his river vessels mainly to the northwest of the city to patrol the marshes and ensure that the fortress was not reinforced. They also kept an eye on the Sava river to the southwest to avoid the infantry from being outflanked by Hunyadi's army. The zone from the Danube eastwards was guarded by the Sipahi, the Sultan's feudal heavy cavalry corps, to avoid being outflanked on the right. 
Question: How many days after Mehmed bombard the city's walls did the siege begin? 
Answer type: Number 
Example Output: 5.
