[EX Q]: Question: How many years did the war last that Eden's great-grandfather commanded the 2nd regiment of foot? Passage 1:One of the earliest incumbents, Sir Walter Mildmay, member for Peterborough from 1553 to 1554, subsequently became Chancellor of the Exchequer from 1559 to 1589. Later, in the nineteenth century, William Elliot, Whig member from 1802 until his death in 1819, was Chief Secretary to the Lord Lieutenant of Ireland between 1806 and 1807; the Hon. William Lamb (later the 2nd Viscount Melbourne), Whig member from 1816 to 1819, became Home Secretary in 1830 then Prime Minister from 1834 to 1841; and Sir James Scarlett (later the 1st Baron Abinger), Whig member from 1819 to 1830, was, from 1827, Attorney General for England and Wales.
 Passage 2:Eden's great-grandfather was William Iremonger, who commanded the 2nd Regiment of Foot during the Peninsular War and fought under Wellington (as he became) at Vimeiro. He was also descended from Governor Sir Robert Eden, 1st Baronet, of Maryland and, through the Calvert Family of Maryland, he was connected to the ancient Roman Catholic aristocracy of the Arundell and Howard families, some of whom were Roman Catholics like the Dukes of Norfolk and others Anglican such as the earls of Carlisle, Effingham and Suffolk. The Calverts had converted to the Established Church early in the 18th century to regain the proprietorship of Maryland. He was also descendant from the Schaffalitzky de Muckadell family of Denmark, and Bie family of Norway. Eden was once amused to learn that one of his ancestors had, like Churchill's ancestor the Duke of Marlborough, been the lover of Barbara Castlemaine.

[EX Q]: Question: How old was Burns when she played as Jessie Owens? Passage 1:Within weeks, many Americans could recite favorite lines from the record, including "the rubber schwan [swan] is mine", and "move ahead...with great vigah [vigor]", the latter lampooning the President's own words. The album poked fun at Kennedy's PT-109 history; the rocking chairs he used for his painful back; the Kennedy clan's well-known athleticism, football games and family togetherness; children in the White House; and Jackie Kennedy's soft-spoken nature and her redecoration of the White House; and many other bits of knowledge that the public was eager to consume. Kennedy himself was said to have given copies of the albums as Christmas gifts, and once greeted a Democratic National Committee group by saying, "Vaughn Meader was busy tonight, so I came myself." According to UPI reporter Merriman Smith, during a Cabinet meeting Kennedy played the entire record for everyone. At one press conference, Kennedy was asked if the album had produced "annoyment (sic) or enjoyment." He jokingly responded, "I listened to Mr. Meader's record and, frankly, I thought it sounded more like Teddy than it did me. So, now he's annoyed."
 Passage 2:From 1998 to 2001, Burns starred in Baywatch as the character Jessie Owens. In 2001, she appeared as Vicki Vale in one of several "Batman" commercials for OnStar, opposite Bruce Thomas's Batman. Burns hosted NBC's Dog Eat Dog from June 2002 to August 2003 and was nominated for a Teen Choice Award. Burns starred in North Shore, a prime-time soap opera that ran for 21 episodes in 2004 and 2005. In 2006, she starred in the WB series Pepper Dennis playing Kathy Dinkle. In 2009, Burns appeared in the first twelve episodes of the updated Melrose Place playing Vanessa, the most recent wife of Dr. Michael Mancini (Thomas Calabro) and mother of his older son's five-year-old son, Noah. Burns was given the chance to participate in the first season of the ABC celebrity diving reality competition Splash but turned it down because of an injury she had received when diving a few years before.
 Passage 3:Prior to the 2004–05 season, the Lakers traded Payton and Rick Fox to the Boston Celtics for center Chris Mihm, small forward Jumaine Jones and point guard Chucky Atkins. While Payton expressed displeasure with the trade, he ultimately did report to Boston and began the 2004–05 season as the Celtics' starting point guard. On February 24, 2005 Payton was traded to the Atlanta Hawks in a deal that brought former Celtic Antoine Walker back to Boston. The Hawks then waived Payton immediately following the trade, and he returned a week later to Boston as a free agent. Payton started all 77 games he played for Boston and averaged 11.3 points per game and 6.1 assists as the Celtics won the Atlantic Division before losing in the first round to the Indiana Pacers.

 Passage 2:Underwater hockey (UWH), also known as Octopush (mainly in the United Kingdom) is a globally played limited-contact sport in which two teams compete to manoeuvre a puck across the bottom of a swimming pool into the opposing team's goal by propelling it with a hockey stick (pusher). It originated in England on November 18 1954 when Alan Blake, a founder of the newly formed Southsea Sub-Aqua Club, invented the game he called Octopush as a means of keeping the club's members interested and active over the cold winter months when open-water diving lost its appeal. Underwater hockey is now played worldwide, with the Confédération Mondiale des Activités Subaquatiques, abbreviated CMAS, as the world governing body. The first Underwater Hockey World Championship was held in Canada in 1980 after a false start in 1979 brought about by international politics and apartheid.
 Passage 3:Baron Lyell, of Kinnordy in the County of Forfar, was a title in the Peerage of the United Kingdom. It was created in 1914 for the Scottish Liberal politician Sir Leonard Lyell, 1st Baronet. He had already been created a baronet, of Kinnordy in the County of Forfar, in 1894. As his son Charles, a Liberal Member of Parliament, died on 18 October 1918 of pneumonia while serving as Assistant Military Attaché to the USA, he was succeeded by his grandson, the second Baron. He was posthumously awarded the Victoria Cross for his actions in North Africa during the Second World War. He was succeeded in the titles by his son, the third Baron, in 1943. He was one of the ninety-two elected hereditary peers that remain in the House of Lords after the passing of the House of Lords Act 1999, and sat on the Conservative benches. The titles became extinct on his death in 2017.
