[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: How many nations comprise the organization that Albania complained to concerning Royal Navy conducting mine-clearing operations in Albanian territorial waters, Passage:The Corfu Channel Incident refers to three separate incidents involving Royal Navy ships in the Straits of Corfu which took place in 1946, and it is considered an early episode of the Cold War. During the first incident, Royal Navy ships came under fire from Albanian fortifications. The second incident involved Royal Navy ships striking mines and the third incident occurred when the Royal Navy conducted mine-clearing operations in the Corfu Channel, but in Albanian territorial waters, and Albania complained about them to the United Nations. This series of incidents led to the Corfu Channel Case, where the United Kingdom brought a case against the People's Republic of Albania to the International Court of Justice. Because of the incidents, Britain, in 1946, broke off talks with Albania aimed at establishing diplomatic relations between the two countries. Diplomatic relations were only restored in 1991.

[Q]: Question: What month did EC publish its first horror story, "Zombie Terror"? Passage:Following the postwar crime comics vogue spearheaded by publisher Lev Gleason's Crime Does Not Pay, which by 1948 was selling over a million copies a month, came romance comics, which by 1949 outsold all other genres, and horror comics. The same month in which Adventures into the Unknown premiered, the comic-book company EC, which would become the most prominent horror-comics publisher of the 1950s, published its first horror story, "Zombie Terror", by the then relatively unknown writer and artist Johnny Craig, in the superhero comic Moon Girl #5. Almost simultaneously,Trans-World Publications issued its one-and-only comic, the one-shot Mysterious Traveler Comics #1 (November 1948), based on the Mutual Broadcasting Network's radio show of that name and including amid its crime and science-fiction stories a reprint of the Edgar Allan Poe adaptation "The Tell Tale Heart", reprinted from Charlton Comics' Yellowjacket Comics #6. Street and Smith also published two issues of "Ghost Breakers" in late 1948. (ibid GCDB)
