Question: How old was Leopoldo Calvo-Sotelo when elected president? Passage:During the process of electing Leopoldo Calvo-Sotelo as Spain's new president in February 1981, Civil Guards and army members broke into the Congress of Deputies and held all deputies at gunpoint. One of the reasons that led to the coup d'état was the increase of ETA's violence. The coup failed after the King called for the military powers to obey the Constitution. Days after the coup, ETA's faction politiko-militarra started its disbanding, with most of its members joining Euskadiko Ezkerra, a leftist nationalist party away from the Abertzale left. General elections were held in 1982, and Felipe González, from the Socialist Workers' Party became the new president, while Herri Batasuna won two seats. In the Basque Country, Carlos Garaikoetxea from the PNV became lehendakari in 1979. During those years, hundreds of members of Herri Batasuna were arrested, especially after some of them sang the Eusko Gudariak in front of Juan Carlos I.

Question: Which states aided the Latin Empire under the benner "Crusader States"? Passage:The Nicaean–Latin wars were a series of wars between the Latin Empire and the Empire of Nicaea, starting with the dissolution of the Byzantine Empire by the Fourth Crusade in 1204. The Latin Empire was aided by other Crusader states established on Byzantine territory after the Fourth Crusade, as well as the Republic of Venice, while the Empire of Nicaea was assisted occasionally by the Second Bulgarian Empire, and sought the aid of Venice's rival, the Republic of Genoa. The conflict also involved the Greek state of Epirus, which also claimed the Byzantine inheritance and opposed Nicaean hegemony. The Nicaean reconquest of Constantinople in 1261 AD and the restoration of the Byzantine Empire under the Palaiologos dynasty did not end the conflict, as the Byzantines launched on and off efforts to reconquer southern Greece (the Principality of Achaea and the Duchy of Athens) and the Aegean islands until the 15th century, while the Latin powers, led by the Angevin Kingdom of Naples, tried to restore the Latin Empire and launched attacks on the Byzantine Empire.

Question: Did the professor Chamberlain studied under author any books? Passage:Chamberlain then went to Geneva, where he studied under Carl Vogt (a supporter of racial typology at the University of Geneva), Graebe, Müller Argoviensis, Thury, Plantamour, and other professors. He studied systematic botany, geology, astronomy, and later the anatomy and physiology of the human body. Under the tutelage of Professor Julius von Wiesner of the University of Vienna, Chamberlain studied botany in Geneva, earning a Bacheliers en sciences (BSc) physiques et naturelles in 1881. His thesis, Recherches sur la sève ascendante (Studies on rising sap), was not finished until 1897 and did not culminate in a further qualification. The main thrust of Chamberlain's dissertation is that the vertical transport of fluids in vascular plants via xylem cannot be explained by the fluid mechanical theories of the time, but only by the existence of a "vital force" (force vitale) that is beyond the pale of physical measurement. He summarises his thesis in the Introduction: Physical arguments, in particular transpirational pull and root pressure, have since been shown to be adequate for explaining the ascent of sap.
