question:
Question: Did the highest scoring fighter ace have any siblings? Passage:After a short rest, the 90th continued across the Moselle River to take Mainz, 22 March, and crossed the rivers Rhine, the Main, and the Werra in rapid succession. Pursuit continued to the Czech border, 18 April 1945, and into the Sudetes mountain range. The division was en route to Prague when they came upon the remaining 1500 emaciated prisoners left behind by the SS at Flossenbürg concentration camp. Today, a memorial wall at the former camp honors the 90th as the liberators of Flossenbürg concentration camp. A week later, word came that the war in Europe ended on 8 May 1945. On that same day, Erich Hartmann, the highest-scoring fighter ace in history, along with a squadron of the elite Jagdgeschwader 52 fighter wing (the highest-scoring fighter wing in history), surrendered to the 90th.

question:
Question: What country's flag flies over the country near the town the Miller performed harbor patrol duty near? Passage:After shakedown along the U.S. East Coast and in the Gulf of Mexico, Jack Miller sailed from Norfolk, Virginia, 13 June 1944, arriving Pearl Harbor 12 July via the Panama Canal Zone and San Diego, California. After more intensive training out of Pearl Harbor, she departed on 24 July screening a convoy to Eniwetok, where she arrived on 2 August. The remainder of the month was spent on patrol and convoy duty. Jack Miller sailed from Eniwetok on 2 September and, after escorting a convoy to Saipan, took up harbor patrol duty there. Antisubmarine patrols, convoy screening, and escort duty kept Jack Miller busy for the next nine months. During this period she sank five mines. In late 1944 Jack Miller came under the command of Lt. Commander Vermont C. Royster; he had served as the White House correspondent of The Wall Street Journal before the war. After the war ended, Lt. Commander Royster would leave the Navy and resume his journalism career at the Wall Street Journal; he would eventually become the paper's editor-in-chief in 1958.

question:
Question: Do dragons appear in Greek Mythology outside of the chimera? Passage:The chimera of Greek mythology appeared in Marvel Comics. It is depicted as a fire-breathing monster with the heads of a lion and a goat next to each other, the front legs of a lion, the wings of a dragon, the hindquarters of a goat, and a snake-headed tail, while also possessing the power of speech. Its history of being the offspring of Echidna and being slain by Bellerophon is still mentioned. At some point, the Chimera was restored to life by Hera to guard the caverns underneath New Olympus. It was accompanied in this job by a Cyclops and some Skeleton Warriors. The Chimera encountered the Agents of Atlas. When it didn't see that they were Olympians, Chimera breathed fire at them, sparking a fight between the heroes and the minions of Hera. Gorilla-Man forced the chimera to set its second head ablaze, causing it to flail around until it was knocked unconscious.
