Question: How old was Francis Ford when John Ford started his career in filmmaking? Passage:John Ford (1894–1973) was an American film director whose career spanned from 1913 to 1971. During this time he directed more than 140 films. Born in Maine, Ford entered the filmmaking industry shortly after graduating from high school with the help of his older brother, Francis Ford, who had established himself as a leading man and director for Universal Studios. After working as an actor, assistant director, stuntman, and prop man – often for his brother – Universal gave Ford the opportunity to direct in 1917. Initially working in short films, he quickly moved into features, largely with Harry Carey as his star. In 1920 Ford left Universal and began working for the Fox Film Corporation. During the next ten years he directed more than 30 films, including the westerns The Iron Horse (1924) and 3 Bad Men (1926), both starring George O'Brien, the war drama Four Sons and the Irish romantic drama Hangman's House (both 1928 and both starring Victor McLaglen). In the same year of these last two films, Ford directed his first all-talking film, the short Napoleon's Barber. The following year he directed his first all-talking feature, The Black Watch.

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.

Question: Why did Red Hood seek revenge on Batman? Passage:Besides the aforementioned death of Stephanie Brown, many other side effects came about from this event. The biggest of these included Black Mask becoming the single crime boss in Gotham, something that would remain until his death at the hands of Catwoman. Another would be Commissioner Akins effectively making all vigilantes criminals, a move that would stay in place for over a year until the return of Commissioner Gordon to the Gotham City Police Department. The more controversial effect, not seen until the follow-up story War Crimes, was turning Doctor Leslie Thompkins against Batman, when she allows Stephanie Brown to die from her wounds as Batman's "punishment" for including children in his war on crime. Jason Todd, a former Boy Wonder, confirmed to be alive on  as a violent vigilante the Red Hood who waged a one-man war against Black Mask and successfully crippling his criminal operation in the city before seeking revenge towards Batman and the Joker. Finally, the citizens of Gotham City no longer consider Batman to be an urban legend (which has been in place since Zero Hour), as he was caught on camera trying to save the life of a wounded student at the end of Act One. Additionally, Barbara Gordon lost the clock tower that served as her home and headquarters and left Gotham City, eventually moving to Metropolis. She would later re-establish her ties to Batman.
