[EX Q]: Question: Did more than 50 million people die in the conflict that forced Clothier to cut his studies short? Passage:Clothier was born in 1919 in Liverpool to a devout Catholic family. He was educated at Stonyhurst College and won a senior history scholarship to read law at Lincoln College, Oxford. The outbreak of the Second World War cut short his studies and he refused to apply for a post in the Judge Advocate General's office in 1939. This led to a twenty-year-long rift with his father, a dentist who had seen dreadful jaw injuries during the First World War. Clothier joined the Royal Signals and served with the 51st (Highland) Division at the Second Battle of El Alamein, where he was responsible for laying communication lines and setting up radio equipment. He undertook deception duties in a radio truck and made transmissions from unmanned positions in English and Scottish accents to confuse the enemy. He discovered that the greatest danger came from enemy aircraft and from a lack of sleep, instanced by an occasion when he woke to discover that he was riding his motorcycle down an embankment into a minefield. Clothier acquired the nickname 'Spike' after a film character. He became a popular pianist in the officers' mess and acquired a love of flying when an American pilot offered a flight and landed on a road by a Sicilian village where they had an impromptu swim. In 1943 Clothier was transferred to Washington, D.C. where he served as a staff officer, sitting on committees dealing with technical developments and radio-frequency allocation. He continued his passion for flying by qualifying as a pilot. He also encountered the actress Mae West who was so impressed with Clothier that she said she would send her son to Oxford University to learn to speak like him. Clothier developed a lasting love of the United States during his time in Washington, D.C. When Clothier left the Army in 1946, he had reached the rank of Lieutenant-Colonel.

[EX Q]: Question: How old was Charles' maternal grandfather when his father was born? Passage:Merivale was the second son of John Herman Merivale (17701844) and Louisa Heath Drury, daughter of Joseph Drury, headmaster of Harrow. He was educated at Harrow School under George Butler from 1818 to 1824, where his chief schoolfriends were Charles Wordsworth and Richard Chenevix Trench. He took part in the Eton versus Harrow cricket match in 1824. In 1824 he was offered a post in the Indian civil service, and went for a short time to Haileybury College, where he did well in Oriental languages. Deciding against an Indian career, he went up to St John's College, Cambridge in 1826. Among other distinctions he came out as fourth classic in 1830, and in 1833 was elected fellow of St John's. He was a member of the Apostles' Club, his fellow-members including Tennyson, A.H.Hallam, Monckton Milnes, W.H.Thompson, Trench and James Spedding. Merivale was the main protagonist on the Cambridge side in instigating the Oxford and Cambridge Boat Race held at Henley on Thames in 1829. He rowed at number four in the Cambridge boat in the race which Oxford won.

[EX Q]: Question: What time of the year (month) does the race usually take place where Nomination beat Green Desert? Passage:Roaring Riva began his racing career by winning a maiden race over five furlongs at Windsor Racecourse and then followed up by taking a minor event over six furlongs at the same track. In early July he was sent to York Racecourse to contest the Black Duck Stakes and finished second, beaten half a length by Nomination, a colt who went on to beat Green Desert in the Richmond Stakes. The colt was then sent to Ireland and moved up in class for the Group 1 Phoenix Stakes over six furlongs on soft ground at Phoenix Park Racecourse. Ridden by Ray Cochrane he started the 4/1 second favourite behind the highly regarded, but previously unraced Tate Gallery, with the best-fancied of the other eleven runners being the unbeaten filly Sherkraine, Devil's Run and Mr John. Roaring Riva was among the leaders from the start, went to the front two furlongs out and held off the challenge of the filly So Directed to win by three quarters of a length. Laing recalled that it was "quite a day. We had private planes, champagne, the lot!"
