input question: I know that the answer to the question "The man who died at the age on 90 rammed a bomber in what year?" is in "On 15 September 1940, known as the Battle of Britain Day, an RAF pilot, Ray Holmes of No. 504 Squadron RAF rammed a German bomber he believed was going to bomb the Palace. Holmes had run out of ammunition and made the quick decision to ram it. Holmes bailed out. Both aircraft crashed. In fact the Dornier Do 17 bomber was empty. It had already been damaged, two of its crew had been killed and the remainder bailed out. Its pilot, Feldwebel Robert Zehbe, landed, only to die later of wounds suffered during the attack. During the Dornier's descent, it somehow unloaded its bombs, one of which hit the Palace. It then crashed into the forecourt of London Victoria station. The bomber's engine was later exhibited at the Imperial War Museum in London. The British pilot became a King's Messenger after the war, and died at the age of 90 in 2005.".

input question: I know that the answer to the question "What property of a metal mixture has the letter R as the third letter?" is in "Iron is usually found as iron ore on Earth, except for one deposit of native iron in Greenland, which was used by the Inuit people. Native copper, however, was found worldwide, along with silver, gold and platinum, which were also used to make tools, jewelry, and other objects since Neolithic times. Copper was the hardest of these metals, and the most widely distributed. It became one of the most important metals to the ancients. Eventually, humans learned to smelt metals such as copper and tin from ore, and, around 2500 BC, began alloying the two metals to form bronze, which is much harder than its ingredients. Tin was rare, however, being found mostly in Great Britain. In the Middle East, people began alloying copper with zinc to form brass. Ancient civilizations took into account the mixture and the various properties it produced, such as hardness, toughness and melting point, under various conditions of temperature and work hardening, developing much of the information contained in modern alloy phase diagrams. Arrowheads from the Chinese Qin dynasty (around 200 BC) were often constructed with a hard bronze-head, but a softer bronze-tang, combining the alloys to prevent both dulling and breaking during use.".

output answer: hardness

input question: I know that the answer to the question "Who was Hayek's most influential teacher?" is in "During Hayek's years at the University of Vienna, Carl Menger's work on the explanatory strategy of social science and Friedrich von Wieser's commanding presence in the classroom left a lasting influence on him. Upon the completion of his examinations, Hayek was hired by Ludwig von Mises on the recommendation of Wieser as a specialist for the Austrian government working on the legal and economic details of the Treaty of Saint Germain. Between 1923 and 1924 Hayek worked as a research assistant to Prof. Jeremiah Jenks of New York University, compiling macroeconomic data on the American economy and the operations of the US Federal Reserve.".

input question: I know that the answer to the question "who was known formally as His Highness Prince Albert of York?" is in "His birthday (14 December 1895) was the 34th anniversary of the death of his great-grandfather, Prince Albert, the Prince Consort. Uncertain of how the Prince Consort's widow, Queen Victoria, would take the news of the birth, the Prince of Wales wrote to the Duke of York that the Queen had been "rather distressed". Two days later, he wrote again: "I really think it would gratify her if you yourself proposed the name Albert to her". Queen Victoria was mollified by the proposal to name the new baby Albert, and wrote to the Duchess of York: "I am all impatience to see the new one, born on such a sad day but rather more dear to me, especially as he will be called by that dear name which is a byword for all that is great and good". Consequently, he was baptised "Albert Frederick Arthur George" at St. Mary Magdalene's Church near Sandringham three months later.[a] As a great-grandson of Queen Victoria, he was known formally as His Highness Prince Albert of York from birth. Within the family, he was known informally as "Bertie". His maternal grandmother, the Duchess of Teck, did not like the first name the baby had been given, and she wrote prophetically that she hoped the last name "may supplant the less favoured one".".

output answer:
Albert Frederick Arthur George
