Input: Read this: Napoleon acknowledged one illegitimate son: Charles Léon (1806–1881) by Eléonore Denuelle de La Plaigne. Alexandre Colonna-Walewski (1810–1868), the son of his mistress Maria Walewska, although acknowledged by Walewska's husband, was also widely known to be his child, and the DNA of his direct male descendant has been used to help confirm Napoleon's Y-chromosome haplotype. He may have had further unacknowledged illegitimate offspring as well, such as Eugen Megerle von Mühlfeld by Emilie Victoria Kraus and Hélène Napoleone Bonaparte (1816–1907) by Albine de Montholon.
Question: Who was the mother of Charles Léon?

Output: Eléonore Denuelle de La Plaigne


Input: Read this: The number of entrants has increased greatly in recent years. In the 2004–05 season, 660 clubs entered the competition, beating the long-standing record of 656 from the 1921–22 season. In 2005–06 this increased to 674 entrants, in 2006–07 to 687, in 2007–08 to 731 clubs, and for the 2008–09 and 2009–10 competitions it reached 762. The number has varied slightly but remained roughly stable since then, with 759 clubs participating in 2010–11, a record 763 in 2011–12, 758 for 2012–13, 737 for 2013–14 and 736 for 2014–15. By comparison, the other major English domestic cup, the League Cup, involves only the 92 members of the Premier League and Football League.
Question: How many clubs entered in 2007-08?

Output: 731


Input: Read this: The Space Race was a 20th-century competition between two Cold War rivals, the Soviet Union (USSR) and the United States (US), for supremacy in spaceflight capability. It had its origins in the missile-based nuclear arms race between the two nations that occurred following World War II, enabled by captured German rocket technology and personnel. The technological superiority required for such supremacy was seen as necessary for national security, and symbolic of ideological superiority. The Space Race spawned pioneering efforts to launch artificial satellites, unmanned space probes of the Moon, Venus, and Mars, and human spaceflight in low Earth orbit and to the Moon. The competition began on August 2, 1955, when the Soviet Union responded to the US announcement four days earlier of intent to launch artificial satellites for the International Geophysical Year, by declaring they would also launch a satellite "in the near future". The Soviet Union beat the US to this, with the October 4, 1957 orbiting of Sputnik 1, and later beat the US to the first human in space, Yuri Gagarin, on April 12, 1961. The Space Race peaked with the July 20, 1969 US landing of the first humans on the Moon with Apollo 11. The USSR tried but failed manned lunar missions, and eventually cancelled them and concentrated on Earth orbital space stations. A period of détente followed with the April 1972 agreement on a co-operative Apollo–Soyuz Test Project, resulting in the July 1975 rendezvous in Earth orbit of a US astronaut crew with a Soviet cosmonaut crew.
Question: What was the date that the first human reached space?

Output: April 12, 1961


Input: Read this: In ultra high vacuum systems, some very "odd" leakage paths and outgassing sources must be considered. The water absorption of aluminium and palladium becomes an unacceptable source of outgassing, and even the adsorptivity of hard metals such as stainless steel or titanium must be considered. Some oils and greases will boil off in extreme vacuums. The permeability of the metallic chamber walls may have to be considered, and the grain direction of the metallic flanges should be parallel to the flange face.
Question: What will grease usually run parallel to?

Output:
unanswerable
