Question: Did Henry VIII or Elizabeth I live longer? Passage:Greenwich is notable for its maritime history and for giving its name to the Greenwich Meridian (0° longitude) and Greenwich Mean Time. The town became the site of a royal palace, the Palace of Placentia from the 15th century, and was the birthplace of many Tudors, including Henry VIII and Elizabeth I. The palace fell into disrepair during the English Civil War and was demolished to be replaced by the Royal Naval Hospital for Sailors, designed by Sir Christopher Wren and his assistant Nicholas Hawksmoor. These buildings became the Royal Naval College in 1873, and they remained a military education establishment until 1998 when they passed into the hands of the Greenwich Foundation. The historic rooms within these buildings remain open to the public; other buildings are used by University of Greenwich and Trinity Laban Conservatoire of Music and Dance.

Question: In what year was Albert Park Circuit opened up for its first race? Passage:Beechey began racing at the age of 22 in a Ford Customline V8. He came to prominence only a year later when he won the Olympic Touring Car Race at Albert Park, a support event at the Australian Grand Prix meeting which was held in conjunction with the 1956 Melbourne Olympic Games. As the expense of running this and two subsequent Customline V8s proved too prohibitive he reverted to a Holden 48-215 in 1959. After becoming part of David McKay’s Scuderia Veloce team he again returned to V8s, developing a Chevrolet Impala with which he won the New South Wales Touring Car Championship at Catalina Park. He progressed to a Ford Galaxie owned by Len Lukey and was then instrumental in forming the Neptune Racing Team in 1964. He raced a Holden EH S4 as part of that team alongside Jim McKeown’s Lotus Cortina and Peter Manton’s Morris Cooper S. He subsequently developed and raced a series of V8 powered Touring Cars with which he contested the Australian Touring Car Championship and other events. The first Ford Mustang to race in Australia was followed by a Chevrolet Chevy II Nova, a Chevrolet Camaro, a Holden Monaro GTS 327 and a Holden Monaro GTS 350.

Question: When did the student newspaper that Morton worked for first begin publishing? Passage:Morton was a prolific photographer who took photographs of all aspects of life in North Carolina. His first published photograph came in 1935, when he was 14; a picture he took of a golfing scene was published as a North Carolina travel advertisement in Time Magazine. During his time at the University of North Carolina, he was a photographer for the student newspaper, the Daily Tar Heel. During World War II, Morton joined as a member of the Signal Corps, where he was assigned the job of newsreel photographer. He was sent to New Caledonia, an island off the coast of Australia, where he was attached to the 37th Infantry Division. Near the end of the war, Morton was assigned to take pictures of General Douglas MacArthur when MacArthur's regular photographer was sick. While on the island of Luzon in the Philippines, Morton was injured by a Japanese explosive and was awarded the Bronze Star and the Purple Heart.
