[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.

[A]: 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


[Q]: Question: Is there a difference in the age of the horses entered to compete in the Royal Lodge Stakes compared to the Sussex Stakes? Passage:Cecil's success in 2011 was partly due to his training of the Khalid Abdullah-owned Frankel. In the 2010 season Frankel won the Royal Lodge Stakes and Group One Dewhurst Stakes. The following year he continued unbeaten, winning the Greenham Stakes, the 2,000 Guineas, the St. James's Palace Stakes at Royal Ascot, the Sussex Stakes and the Queen Elizabeth II Stakes. His six length victory in the 2,000 Guineas was described as "one of the greatest displays on a British racecourse". After his win in the Sussex Stakes Cecil himself described Frankel as "the best horse I've ever seen". Timeform and the International Federation of Horseracing Authorities rated him the best horse in the world. In his four-year-old season Frankel won the Group One Lockinge Stakes at Newbury before an eleven length victory in the Queen Anne Stakes at Royal Ascot, described in one national newspaper as "possibly the best single performance by any horse, on any track, since three Arabian stallions were imported into Britain to found the thoroughbred breed in the early years of the 18th century". Timeform raised their rating to 147, making Frankel the highest rated horse in their history. He won a second Sussex Stakes, at odds of 1–20, and then stepped up in distance to win by seven lengths the Juddmonte International Stakes at York over 10 furlongs. In October 2012 Frankel won the Champion Stakes at Ascot to finish his career unbeaten. "He's the best I've ever had, the best I've ever seen", Cecil told the BBC after the race, "I'd be very surprised if there's ever been a better."

[A]: In the 2010 season Frankel won the Royal Lodge Stakes and Group One Dewhurst Stakes


[Q]: Question: In what year was the 25th Amendment passed? Passage:McKellar twice served as President pro tempore of the United States Senate, commencing in 1945, the first to hold the position under the system that has prevailed since of reserving it for the most senior member of the majority party. When Harry Truman became president in April 1945, upon FDR's death, the vice presidency became vacant (the mechanism for filling intra-term vacancies had not yet been created by the 25th Amendment), and so McKellar became the permanent presiding officer of the United States Senate. Also, as the President pro tempore of the Senate had, prior to 1886, been second in the presidential line of succession, behind only the vice president, Truman viewed McKellar as the logical wartime replacement for himself, and asked McKellar to attend all Cabinet meetings. In 1947 Truman successfully lobbied Congress to pass a new Presidential Succession Act restoring both the Speaker of the House and the President pro tempore of the Senate to the succession ahead of the Cabinet secretaries. By the time the law came into effect, McKellar was no longer in the position of President pro tempore, because Republicans held the majority in the 80th Congress. Truman vetoed the Taft-Hartley Act in 1947 to restrict labor unions, which McKellar voted in favor of. As such Truman selected Alben Barkley of Kentucky as his running mate in the 1948 presidential election. When Democrats regained control as a result of the 1948 elections, McKellar again became President pro tempore. He was therefore second in line for the presidency (behind the Speaker of the House) from January 3, 1949 until January 20, 1949, when Alben Barkley took office as Vice President of the United States.
