Q: Question: How many nations were part of the powers that occupied Serbia? Passage 1:From Perth, a number of Garnaut's family had previously played top-level sports: his grandfather, Laurie (), father, John (East Perth), and brother, Graeme (East Perth, and ) all played WAFL senior football, and his sister, Kristin, played netball for the Perth Orioles. Garnaut played Teal Cup football for Western Australia, and later played one senior match for East Perth in the WAFL in 1994. He later concentrated on cricket, making his first-class debut against South Australia in November 1996. Overall, he played 16 matches for Western Australia in the 1996–97 and 1997–98 Sheffield Shield competitions, taking 37 wickets at an average of 42.00, with a best of 4/51. Garnaut also played grade cricket for the Bayswater-Morley District Cricket Club. He was involved in a notable incident during the 1998–99 WACA First Grade final against Midland-Guildford, when he and Bret Mulder, batting tenth and eleventh respectively, put on 177 for the tenth wicket to win the tournament for Bayswater-Morley, with Garnaut finishing on 127 not out.
 Passage 2:The eighth season of Stargate SG-1, an American-Canadian military science fiction television series, began airing on July 9, 2004 on the Sci Fi channel. The eighth season concluded on February 22, 2005, after 20 episodes on British Sky One, which overtook the Sci Fi Channel in mid-season. This was the first season of the show to have 20 episodes instead of 22, as well as the first to air concurrently with Stargate SG-1 spinoff series Stargate Atlantis (the first season thereof). The series was originally developed by Brad Wright and Jonathan Glassner, while Brad Wright and Robert C. Cooper served as executive producers. Season eight regular cast members include Richard Dean Anderson, Amanda Tapping, Christopher Judge, and Michael Shanks. The eighth season begins with the SG-1 team trying to revive Colonel Jack O'Neill (Richard Dean Anderson) after the events of the seventh season. At the end of the two-episode season opener, Colonel O'Neill is promoted to General and assumes command of Stargate Command (SGC), while Major Samantha Carter (Amanda Tapping) is promoted to Lieutenant Colonel and assumes command of SG-1. The season arc centers on the growing threat and seemingly final defeat of the Goa'uld and the Replicators, races who were introduced in the first and third season of the show, respectively.
 Passage 3:Tomić belonged to the first class of six Serbian pilots trained in France in 1912. In August 1914, he participated in the first aerial dogfight of the war, when he exchanged gunfire with an Austro-Hungarian plane over western Serbia. In the winter of 1915, during the Serbian Army's retreat across Albania to the Greek island of Corfu, he evacuated General Petar Bojović from Scutari by plane, delivered mail by air and transported the Serbian Government's gold and hard currency reserves from Niš to keep them from falling into enemy hands. Following the occupation of Serbia by the Central Powers, Tomić went to France and flew over the Western Front, where he had one confirmed kill. He returned to the Balkans in late 1916, conducted combat missions over Bulgarian-occupied Macedonia and shot down one enemy plane. Tomić continued flying after the war and became head of the Royal Yugoslav Air Force's pursuit squadron in Novi Sad. During World War II, he was captured by the Germans and detained as a prisoner of war. Tomić left Yugoslavia following the war and settled in the United States with his wife. He died in Chicago in 1962.
