Question: Question: What age was Socarras when Batista returned from Florida to run for president? Passage:Fulgencio Batista y Zaldivar (; ; born Ruben Zaldivar; 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 Cespedes 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 Prio Socarras that preempted the election.

Answer: After finishing his term he lived in Florida, returning to Cuba to run for president in 1952

Question: Question: How old was the German king Thomas alerted of his ascension when Tvrtko died? Passage:Tvrtko II died in November 1443. The Stanak approved his choice of heir, and Thomas was duly elected king by 5 December. Like his predecessors, he added the royal name Stephen to his own. However, the kingdom's most powerful magnate, Grand Duke Stjepan Vukcic Kosaca, refused to accept Thomas as king, and announced his support for Radivoj. The authorities of the neighbouring Republic of Ragusa immediately expressed concern about the situation. Kosaca and Radivoj appealed to Ragusa not to recognize Thomas as king, but to no avail. Simultaneously, Hermann's grandson Ulrich II pressed his claim to the Bosnian throne and tried to gather support among Thomas's opponents. Because of this, Thomas hastened to send word of his accession to foreign rulers, including the German king Frederick IV, Ulrich's rival, and Ragusan and Venetian authorities, hoping to receive recognition. Ulrich was occupied with the feud waged against him by Frederick, as well as with the succession struggle in Hungary, where he had taken side with his cousin, queen dowager Elizabeth of Luxembourg and her infant son Ladislaus against the reigning monarch Vladislav I, leaving Thomas ample space of maneuver.

Answer:
Because of this, Thomas hastened to send word of his accession to foreign rulers, including the German king Frederick IV, Ulrich's rival, and Ragusan and Venetian authorities, hoping to receive recognition
