Question: How many artists had won the gold medal from the Royal British Society of Sculptors before Montford did? Passage 1:Montford was president of the Victorian Artists Society 1930–32. His generally good work as president was occasionally marred by a certain lack of tact. Some of Montford's best work about this period included the bronzes, "Water Nymph" and "Peter Pan", now in the Queen Victoria Gardens, Melbourne, and "The Court Favourite" in the Flagstaff Gardens, Melbourne. Other work includes relief portraits of eight Australian statesmen in the King's Hall, Parliament House, Canberra, and the war memorial for the Australian Club, Sydney. He was greatly encouraged and pleased on learning in 1934, that his statue of Adam Lindsay Gordon at Melbourne had been awarded the gold medal of the Royal British Society of Sculptors for the best piece of sculpture of the year. Another excellent piece of work is his vigorous statue of John Wesley in front of Wesley Church, Melbourne. His George Higinbotham near the treasury is less successful. Other examples of Montford's work are the memorials to Carlo Catani (St Kilda), William Benjamin Chaffey (Mildura), Sir Ross Macpherson Smith (Adelaide), and 'Pioneer Women' (Sydney). Montford is represented in the National Gallery of Victoria in Melbourne by "Atalanta", the "Spirit of Anzac", and two busts, and he is also represented in the Art Gallery of South Australia in Adelaide. He provided a model from which a portrait bust of Socrates was carved for the University of Western Australia by Victor Wager in 1932.
 Passage 2:After military service in the Imperial Russian Army in World War I, where he reached the rank of a colonel, he joined the 1st Polish Corps of General Józef Dowbor-Muśnicki in western Russia from December 1917 until the Germans forced its dissolution in July 1918. He helped Walerian Czuma organise 1st Kosciuszko regiment at Samara in August 1918 which later formed the 5th Rifle Division in Siberia (sometimes known as the Polish Legion or the Siberian Division) which fought alongside the Czech Legion and the White movement in the Russian Civil War. When the White government of Admiral Aleksandr Kolchak collapsed in December 1919, the Polish Legion joined the general retreat along the Trans-Siberian Railway, until it was surrounded by the Red Army east of Krasnoyarsk in early January 1920. Refusing to surrender, Rumsza led 900 officers and men on an ice march through the taiga slipping through Bolshevik forces until they reached Irkutsk. From there they managed to escape to Harbin in White-controlled Manchuria, and thence to Vladivostok. Rumsza’s force arrived at Gdańsk (Danzig) in Poland in June 1920 and volunteered to fight in the Polish-Soviet War which had just broken out. 
 Passage 3:George W. Bush used "I Won't Back Down" at campaign events during the 2000 presidential campaign but was compelled to stop using the song after receiving a cease and desist letter from Petty's publisher. Petty then went on to perform the song at Al Gore's home after Gore conceded the election to President Bush. Jim Webb used the song for his successful bid for one of Virginia's U.S. Senate seats in 2006, as did Hillary Clinton during the 2008 Democratic presidential primary campaign. The song was also used at campaign events for Congressman Ron Paul of Texas during the 2008 Republican presidential primary campaign, as well as for events for his Campaign for Liberty. The song was also played at an event for Republican Connecticut gubernatorial nominee, Tom Foley. The song was also played at the 2012 Democratic National Convention after speech delivered by President Bill Clinton, in which President Barack Obama came out on stage to salute him.

 Passage 2:Casualty is a British medical drama television series that premiered on 6 September 1986 on BBC One. The series was created by Jeremy Brock and Paul Unwin. It is set in the fictional Holby City Hospital, in the equally fictitious city of Holby, and features occasional crossovers of characters and plots with spin-off show Holby City. Casualty follows the professional and personal lives of the doctors, nurses, paramedics, hospital management and patients at Holby General. It features an ensemble cast of regular characters, and began with 10 main characters in its first series, all but two – Charlie Fairhead (played by Derek Thompson) and Lisa "Duffy" Duffin (played by Cathy Shipton) – have since left the show. Many main characters have been written in and out of the series since. In addition, Casualty features guest stars each week, as well as recurring guests that take part in story arcs that span a portion of a series or multiple series.
 Passage 3:Anna Kraus, Op. 30 is a radio opera in one act by composer Franz Reizenstein. The work uses an English language libretto by Christopher Hassall to tell the tragic tale of a German woman who is forced to leave her country due to oppression from the Nazi regime, as the Nazis did not like her political views. The opera was commissioned by the British Broadcasting Corporation following the popular success of Reizenstein's 1951 cantata Voices of Night. The opera premiered on 25 July 1952 on BBC Third Programme with conductor Norman Del Mar leading the BBC Symphony Orchestra and singers Victoria Sladen (as Anna) and Lloyd Strauss-Smith (as Pavel). It was submitted by the BBC later that year for the Prix Italia. Critical reaction to the work was mixed. The New Statesman described the work as "engaging" and a "worthwhile experiment". The Annual Register wrote that the opera "suffered from the composer's emotion being too closely engaged in the sufferings of the heroine, a refugee from political oppression".

Question: In what country was No. 71 formed? Passage 1:On November 6, 2017, CNBC reported The Walt Disney Company was negotiating a deal with Rupert Murdoch to acquire 21st Century Fox's filmed entertainment, cable entertainment, and direct broadcast satellite divisions, including 20th Century Fox, FX Networks, and National Geographic Partners. The deal would reportedly exclude the Fox Broadcasting Company, 20th Century Fox's studio lot, Fox Television Stations, Fox News Group, and Fox Sports, which would be spun off into a new independent company run by the Murdoch family. According to Disney's CEO Bob Iger, the idea of purchasing Fox's assets came after Disney acquired majority control of the streaming company BAMTech with anticipation to develop its own streaming service (which would eventually be called Disney+, launched in November 2019). Disney was less interested in Fox's production capacities and more keen to acquire Fox's own film and television libraries to help expand the streaming service's library.
 Passage 2:At the start of the Second World War before the US entered the war, there were a large number of American volunteers offering their services. No. 71 was formed at RAF Church Fenton on 19 September 1940 with Brewster Buffalos. Appraisal by Royal Air Force acceptance personnel criticised the Brewster Buffalo on numerous points, including lack of armament and pilot armour, poor high-altitude performance, engine overheating, unreliability and cockpit controls, while it was praised for its handling, roomy cockpit and visibility. The aircraft were deemed unsuitable for European conditions and Hawker Hurricanes replaced them from November 1940. The squadron became operational at RAF Kirton-in-Lindsey on 5 February 1941 and moved in April to RAF Martlesham Heath in Suffolk for operations over Europe. During May, it suffered its first loss when Mike Kolendorski was killed during a fighter sweep over the Netherlands. The intensity of operations stepped up with a move into No 11 Group of Fighter Command, being based at RAF North Weald in Essex by June 1941. On 2 July, William J. Hall became the first Eagle Squadron pilot to become a Prisoner of War (POW) when he was shot down during an escort mission. The squadron's first confirmed victory came on 21 July 1941 during a bomber escort mission, when Pilot Officer William R. Dunn destroyed a Messerschmitt Bf 109F over Lille. In August, the Spitfire Mk II replaced 71 Squadron's Hurricanes, before the squadron quickly re-equipped with the latest Spitfire Mk VB. The unit soon established a high reputation, and numerous air kill claims were made in RAF fighter sweeps over the continent during the summer and autumn of 1941. In December, the Squadron was rested back at Martlesham Heath, before a move to Debden in May 1942. When informed of the attack on Pearl Harbor, most of the Eagle Squadron pilots wanted to immediately join the fight against Japan. Representatives from 71 and 121 Squadrons went to the American Embassy in London and offered their services to the United States. The pilots from 71 Squadron decided they wanted to go to Singapore to fight the Japanese and a proposal was put to RAF Fighter Command, but it was turned down. On 29 September 1942 the squadron, together with the other two Eagle squadrons, was transferred to the US Army Air Forces, becoming the 334th Fighter Squadron of the 4th Fighter Group.
 Passage 3:After the beginning of World War I in August 1914, Swiftsure escorted troop convoys in the Indian Ocean until she was transferred to the Suez Canal Patrol in December. After defending the Canal in early 1915 from Ottoman attacks, the ship was then transferred to the Dardanelles in February and saw action in the Dardanelles Campaign bombarding Ottoman fortifications. Triumph participated in the hunt for the German East Asia Squadron of Maximilian Graf von Spee and in the campaign against the German colony at Tsingtao, China. The ship was transferred to the Mediterranean in early 1915 to participate in the Dardanelles Campaign. She was torpedoed and sunk off Gaba Tepe by the German submarine on 25 May 1915.
