Question: Which city had more citizens the year Yeo was born, Southampton or Winchester? Passage 1:He was born at Launceston in Tasmania to draper Alexander Morrison McLaren and Elsie Elizabeth Gibbins. He attended Caulfield Grammar School and then the University of Melbourne, becoming an accountant. In 1938 he embarked on a world tour, returning in 1939. He served in the Royal Australian Navy from 1942 to 1945 and returned to become a partner in the accountancy firm Harris & McLaren. On 16 April 1941 he married Eileen Porter, with whom he had four children. From 1945 to 1947 he was the independent member for Glen Iris in the Victorian Legislative Assembly. Following his defeat he joined the Liberal Party, and served on Malvern City Council from 1951 to 1953. From 1957 to 1963 he was national president of the YMCA, and he served as world vice-president from 1961 to 1969; he was also awarded the OBE in 1959. In 1965 he returned to the Legislative Assembly as the Liberal member for Caulfield, changing seats to Bennettswood in 1967. From 1973 he was Deputy Speaker. McLaren retired from politics in 1979, and died in 2000.
Passage 2:Yeo was born in Southampton, England on 7 October 1782 to a naval victualling agent. Yeo was sent to an academy near Winchester for his formal education. Yeo joined the Royal Navy as a midshipman aboard at the age of 10, thanks to his patron, Admiral Phillips Crosby. In 1796, he was made acting-lieutenant and placed in command of the 16-gun sloop . He was made lieutenant permanently on 20 February 1797. The vessel was deployed to the West Indies, where Yeo contracted Yellow fever was ordered home to England to convalesce in 1798. By 1802, Yeo was first lieutenant aboard in the Adriatic Sea. He distinguished himself during the siege of Cesenatico in 1800, when thirteen merchant vessels were burned or sunk. Following the Peace of Amiens in 1802, Yeo was demoted to half-pay.
Passage 3:Like his father, Mellon consistently supported the Republican Party, and he frequently donated to state and local party leaders. Through state party boss Matthew Quay, Mellon influenced legislators to place high tariffs on aluminum products in the McKinley Tariff of 1890. During the early 20th century, Mellon was dismayed by the rise of progressivism and the antitrust actions pursued by the presidential administrations of Theodore Roosevelt, William Howard Taft, and Woodrow Wilson. He especially opposed the Taft administration's investigations into Alcoa, which in 1912 signed a consent decree rather than going to trial. In the aftermath of World War I, he provided financial support to Henry Cabot Lodge and other Republicans in their successful campaign to prevent ratification of the Treaty of Versailles. Mellon attended the 1920 Republican National Convention as a nominal supporter of Pennsylvania Governor William Cameron Sproul (Mellon hoped Senator Philander Knox would win the nomination), but the convention chose Senator Warren G. Harding of Ohio as the party's presidential nominee. Mellon strongly approved of the party's conservative platform, and he served as a key fundraiser for Harding during the presidential campaign.

Question: What country was Hope sent to after Erskine's death? Passage 1:The East Lost Angeles freeway system and the East Los Angeles Interchange serve as an important center for the Los Angeles freeway network. It is also known for being the cause of displacing countless Mexican Angeleno communities, as 19 percent of East Los Angeles is intertwined with freeways. The freeway system grew as multiple freeways were built over two decades: the Santa Ana (5) Freeway (1944), the Hollywood (101) Freeway (1948), the San Bernardino (10) Freeway (1953), the Santa Monica (10) Freeway (extended to the East Los Angeles Interchange in 1961), the Long Beach (710) Freeway (1961), and the Pomona (60) Freeway (1965).Boyle Heights and neighboring communities protested against the first construction phases of the freeways. Community leaders rallied together to fight for their neighborhoods as they circulated petitions and organized public hearings. The construction of the freeways started as scheduled despite the resistance. The numerous freeways in this era displaced many East Los Angeles residents as they had their homes and property seized. Schools, churches, and community parks were also lost from construction. One notable structure lost in Boyle Heights was Saint Isabella Church and the Catholic elementary school. The loss of Hollenbeck Park was also a devastation to the community, since there was already a shortage of parks in the area. The Divide of Highways again justified the loss of communities by contending that residents would save time using the new freeways. Boyle Heights was a densely populated area because of low mortgages that were enjoyed by Mexican Angelo families. When families were forced to give up their homes they struggled to find homes that matched in affordability. Some families were also displaced in gang ridden areas and further from the freeways that they never used. The remaining residents in the area also still suffer the consequences of the construction of the surrounding freeways. Residents are now separated from parts of the community and face many effects of the area's air pollution caused by vehicles.
Passage 2:Hope joined the Scots Brigade as a cadet in 1778. The Brigade, in the service of the Dutch Republic, was then stationed at Bergen op Zoom and later moved to Maastricht. He had reached the rank of Captain when like other officers he left the Dutch service in 1782 during the Fourth Anglo-Dutch War and was on half-pay until 29 September 1787, when he joined the 60th Foot (Royal American Regiment), but the regiment was reduced and he was briefly on half-pay again before joining the 13th Light Dragoons on 30 June 1788. In February 1793, shortly after the French Revolutionary War had begun, Hope served as aide-de-camp to Sir William Erskine in the Flanders Campaign. On 25 March 1795, a few days after Erskine's death, Hope was promoted to major in the 28th Light Dragoons, becoming lieutenant-colonel of that regiment on 20 February 1796. Sent to the Cape Colony, the 28th, under Hope's command, helped to rebuff a Dutch attempt in August, to reclaim the colony.
Passage 3:Emmanuel was born on 2 March 1989 in Southend-on-Sea, a seaside resort town in Essex, England. Emmanuel is the second child of a half Dominican (Dominiquais) and half English mother, and a father of half-Saint Lucian and half English descent. Emmanuel demonstrated an affinity for the arts at an early age; she recalled that her mother first took notice of her passion and desire to become an actress during Emmanuel's attendance at the independent St Hilda's School (now closed) and later grammar Westcliff High School for Girls. In an interview with the New York Daily News, she commented, "When I was 3, [I'd] always cause drama that my mum decided maybe I should channel it properlyso she started me on acting, singing and dancing classes". At the age of 10, she played Young Nala in the West End production of the musical The Lion King.

Question: Who received the Gold Medal when Heutz received the Silver? Passage 1:Born in Kidbrooke, London, Stanislas first joined West Ham United as a schoolboy at the age of 10. In May 2006, Stanislas signed a three-year academy scholarship. He made his Premier Academy League debut in a 32 defeat to Watford on 8 April 2006, at the age of 16. He became a regular for the Academy in the 200607 season, appearing 26 times and scoring 9 goals as West Ham finished as runners-up to Arsenal. He carried his goalscoring form into the 200708 season, scoring 10 goals in 24 appearances. He made his Premier Reserve League debut on 29 August 2007, in a 21 defeat to Aston Villa. His first goals came in the 80 rout over Derby County, as he netted a brace. He was part of the first-team squad that travelled to North America in the summer of 2008 for the pre-season tour. He started the 200809 season in the reserves, scoring his first goal of the season on 21 October 2008, in a 10 home win over Arsenal.
Passage 2:Heutz joined Imperial College London in 2007 as a Royal Society Dorothy Hodgkin Research Fellow. She was awarded the 2008 Institute of Materials, Minerals and Mining Silver Medal for her research on organic thin films. In particular she had developed new electron - donor morphologies for efficient solar cells. Heutz specialises in the use of electron paramagnetic resonance (EPR) to monitor unpaired electrons within materials. She used EPR to monitor spins within copper phthalocyanine solar cells. Whilst working on new materials for photovoltaics, Heutz showed that electrons in copper phthalocyanine (a blue pigment found in a Bank of England 5 note) exist in a superposition of two different spin states. She demonstrated that copper phthalocyanine could be used for quantum computing, where information is stored as qubits as opposed to binary bits.
Passage 3:The following year a Combined Leeward and Windward Islands team played a first-class match against Guyana in the 1976/77 Shell Shield. In 1978, the ground held its first List A match when the Leeward Islands played Trinidad and Tobago in the 1977/78 Geddes Grant/Harrison Line Trophy. Throughout the 1970s, the ground was continuously used by Montserrat in its minor matches against regional neighbours. A second List A match was played there in 1980, between the Leeward Islands and Trinidad and Tobago in the 1979/80 Geddes Grant/Harrison Line Trophy, while the following year a further first-class match was played there when the Leeward Islands played a touring England XI. The next first-class fixture there came two years later, when the Leeward Islands played Jamaica in the 1982/83 Shell Shield. Two further List A matches were played there in the 1980s, the first seeing the Leeward Islands play Guyana in the 1984/85 Geddes Grant/Harrison Line Trophy, while the second saw them play the Windward Islands in the 1987/88 competition. Again in use by Montserrat throughout the 1980s, first-class cricket would not return there until 1994, when the Leeward Islands played Trinidad and Tobago in the 1993/94 Red Stripe Cup. The previous year, it had held a List A match between the Leeward Islands and Barbados in the 1992/93 Geddes Grant Shield. Unknowingly at the time, these would be the last major matches to be played there.
