Question: Was Carlos Manuel still alive when Batista was elected President of Cuba? Passage:Fulgencio Batista y Zaldívar (; ; born Rubén Zaldívar; January 16, 1901 – August 6, 1973) was a Cuban military officer and politician who served as the elected President of Cuba from 1940 to 1944, and as its U.S.-backed military dictator from 1952 to 1959, before being overthrown during the Cuban Revolution. Batista initially rose to power as part of the 1933 Revolt of the Sergeants, which overthrew the provisional government of Carlos Manuel de Céspedes y Quesada. He then appointed himself chief of the armed forces, with the rank of colonel, and effectively controlled the five-member "pentarchy" that functioned as the collective head of state. He maintained this control through a string of puppet presidents until 1940, when he was himself elected President of Cuba on a populist platform. He then instated the 1940 Constitution of Cuba and served until 1944. After finishing his term he lived in Florida, returning to Cuba to run for president in 1952. Facing certain electoral defeat, he led a military coup against President Carlos Prío Socarrás that preempted the election.

Question: When was the spaceship which attached to the mother ship created? Passage:Baxter publicly credits his fascination with the space program to reading From the Earth to the Moon by Jules Verne as a young boy. Baxter holds the distinction of First Founder of Virgin Galactic, a space tourism company announced by Sir Richard Branson on September 25, 2004. Baxter purchased the first commercial space flight ticket at $200,000 USD after viewing a 60 Minutes segment featuring Burt Rutan, winner of the $10,000,000 X Prize for the first non-governmental organization to launch a reusable manned spacecraft into space twice within two weeks, and thereafter, earning him the nickname "Rocket Man". Rutan is also the designer of Sir Richard Branson's SpaceShipTwo, which attached to the mother ship, will be carried to about 16 kilometers or 52,000 feet by a carrier aircraft, White Knight Two. At that point, when the carrier aircraft reaches its maximum height, the SpaceShipTwo vehicle will separate and continue to over 100 km (the Kármán line, a common definition of where "space" begins). Despite the crash of the first iteration of SpaceShipTwo during a test flight on October 31, 2014, Baxter remains optimistic about his upcoming flight and continues to hold his place at the top of the passenger list to become the world's first commercial space tourist.
