Question: Who governed Noricum after the Romans turned it into a province? Passage:Archaeological findings in the area date back to the Neolithic era, especially the stilt houses of the Mondsee group culture, who settled the region from about 3800 BC onwards. The Germanic name hall of several settlements refers to the region's numerous salt mines, which had been in use at least since the days of the Celtic Hallstatt culture, centered at the mining town of Hallstatt. These operations were continued by the Romans, after the area had been incorporated into the Noricum province in 15 BC. A Roman settlement and salt evaporation pond at Hallstatt is documented about 100, affected by several Germanic invasions after the Marcomannic Wars, until the province was finally evacuated at the behest of the Italian king Odoacer in 488.

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.
