Q: Question: Which son was born first? Passage:Darius was the son of Hystaspes and the grandson of Arsames. Both men belonged to the Achaemenid tribe and were still alive when Darius ascended the throne. Darius justifies his ascension to the throne with his lineage. He claimed he could trace his ancestors back to Achaemenes, even though he was only distantly related. With this in mind, Darius married Atossa, daughter of Cyrus, with whom he had four sons: Xerxes, Achaemenes, Masistes and Hystaspes. He also married Artystone, another daughter of Cyrus, with whom he had two sons, Arsames and Gobryas. Darius married Parmys, the daughter of Bardiya, with whom he had a son, Ariomardus. Furthermore, Darius married Phratagune, with whom he had two sons, Abrokomas and Hyperantes. He also married another woman of the nobility, Phaidyme, the daughter of Otanes. It is unknown if he had any children with her. Before these royal marriages, Darius had married an unknown daughter of his good friend and lance carrier Gobryas from an early marriage, with whom he had three sons, Artobazanes, Ariabignes and Arsamenes. Any daughters he had with her are not known. Although Artobazanes was Darius's first-born, Xerxes became heir and the next king through the influence of Atossa; she had great authority in the kingdom as Darius loved her the most of all his wives.

Q: Question: Which publication that Cannon contributed more substantial articles to came into existence first? Passage:Helped by his association with The Guardian, Cannon was able to contribute more substantial articles to the Los Angeles Times and the Chicago Sun-Times, and to underground magazines such as Creem. He wrote the 1970 documentary film London Rock, focusing on the UK's counterculture movement. He recalls that, together with Rolling Stone journalists David Dalton and Jonathan Cott, he joined Granada Television documentary-makers such as Jo Durden-Smith, John Sheppard and Michael Darlow in devising "prime-time networked shows designed as anthems of the revolution". Among these late-1960s projects, he says that the Johnny Cash at San Quentin TV special was his idea, and he "share[s] credit" for the ideas behind the concert films The Doors Are Open and The Stones in the Park. He also directed the film of Frank Zappa's performance at the 1970 Palermo Pop Festival, for RAI, Italy's national public broadcaster.

Q: Question: What was the population of Sofia the year that Binding was there to lecture intellectuals? Passage:In 1860 Binding moved to Göttingen where he studied history and jurisprudence. After a short stay in Heidelberg, where he won a law prize, he moved back to Göttingen to finish his studies. In 1864 he completed his habilitation paper in Latin about Roman criminal law and lectured in criminal law at Heidelberg University. Two years later he was appointed professor of law of state and criminal law and procedure in Basel, Switzerland. In the same year he married Marie Luise Wirsing and published Das burgundisch-romanische Königreich and Entwurf eines Strafgesetzbuches für den Norddeutschen Bund. At this time he also became friends with Johann Jacob Bernoulli - an archaeologist, Jakob Burckhardt - an art historian, and Friedrich Nietzsche - a philosopher. In August 1867 his first son, Rudolf Georg, was born, followed two years later by his second son. Rudolf G Binding later became a famous writer. Karl Binding and his wife were to have one more son and two daughters. In 1869 his family moved to Freiburg, and Binding volunteered to fight in the Franco-Prussian War. Although his lack of military training meant he was unable to serve as a soldier, he was accepted as an orderly and posted to the front, serving in a field hospital. In 1872 he took on a post at the Reichs University in Straßburg. In the same year he moved to Leipzig University, where he was to continue to work for the next 40 years. From 1879 until to 1900 Binding worked in the district court of Leipzig. After becoming Leipzig University's rector and receiving his emeritus, he moved to Freiburg, where his wife died only a few days later at 71 years old. In 1918, during the First World War, Binding left Germany to lecture German soldiers in Macedonia and Bulgarian intellectuals in Sofia.
