[EX Q]: Question: How old was the military engineer who scouted around Leith during the siege? Passage 1:After completing his secondary education at Highgate School, he attended King's College, Cambridge, earning his PhD in theoretical (high-energy) particle physics in 1971. After brief post-doc positions at SLAC and Caltech, he went to CERN and has held an indefinite contract there since 1978. He was awarded the Maxwell Medal and the Paul Dirac Prize by the Institute of Physics in 1982 and 2005 respectively, and is an Elected Fellow of the Royal Society of London since 1985 and of the Institute of Physics since 1991. He was awarded an Honorary Doctorate from the University of Southampton, and twice won the First Award in the Gravity Research Foundation essay competition (in 1999 and 2005). He is also Honorary Doctor at Uppsala University.
Passage 2:The English King Henry VIII, angered by the Scots reneging on the initial agreement, made war on Scotland in 15441549, a period which the writer Sir Walter Scott later christened the "Rough Wooing". In May 1544 an English army landed at Granton and captured Leith to land heavy artillery for an assault on Edinburgh Castle, but withdrew after burning the town and the Palace of Holyrood over three days. Three years later, following another English invasion and victory at Pinkie Cleugh in 1547, the English attempted to establish a "pale" within Scotland. Leith was of prime strategic importance because of its vital role as Edinburgh's port, handling its foreign trade and essential supplies. The English arrived in Leith on 11 September 1547 and camped on Leith Links. The military engineer Richard Lee scouted around the town on 12 September looking to see if it could be made defensible. On 14 September the English began digging a trench on the south-east side of Leith near the Firth of Forth. William Patten wrote that the work was done as much for exercise as for defence, since the army only stayed for five days.
Passage 3:Pieter van Laer (1599 c. 1642) was a Dutch Golden Age painter of genre scenes, active for over a decade in Rome, where his nickname was Il Bamboccio. Artists working in his style, who often painted just such scenes of everyday life as Pliny lists, became known as the Bamboccianti, painters in Bamboccio's manner. Peiraikos is often mentioned in the controversies over the Bamboccianti, for example by Salvator Rosa in his Satires, and later by the Dutch biographer of artists, Samuel Dirksz van Hoogstraten in his Inleyding tot de Hooge Schoole der Schilderkonst (Introduction to the Academy of Painting), Rotterdam 1678. As genre painting became an important element of Dutch Golden Age painting, Peiraikos was used to provide classical precedent for such work, in the relatively few discussions of the appropriateness of such art by Karel van Mander in his Schilder-boeck (1604) and Arnold Houbraken in his The Great Theatre of Dutch Painters (17181719). Having originally been often rather cheap, by the late 17th century the best Dutch genre scenes became sought after by collectors across Europe at very high prices, a development following Pliny's account of Peiraikos that was bemoaned by Lessing in his Laocoon (1763), mentioning Dutch painting specifically.

Passage 2:In 2000, Schlesinger played in all 16 games for the fifth time in six NFL seasons and second year as the Lions' starting fullback. His 15 special teams tackles tied for fifth on squad as well. In 2001, the Lions named Marty Mornhinweg head coach and the team moved away from a power rushing attack to the west coast offense. The fullback, in addition to rushing and blocking responsibilities, can also be more involved in the passing game. Schlesinger finished the 2001 season with single-season career highs in rushing attempts (47), rushing yards (154), rushing touchdowns (three), receptions (60), and receiving yards (466). On the year Schlesinger rushed for 16 first downs, the only season of his career he accumulated a double-digit total in the category. For his efforts during the season, he was voted the Chuck Hughes Most Improved Player by teammates and was also voted onto Howie Long's Tough Guy team. He was also named to the 2001 All-Pro Team by Sports Illustrateds Paul Zimmerman and to the College and Pro Football Newsweekly 2001 All-Pro Second Team squad. In 2002, he finished the year with 139 rushing yards and two rushing touchdowns along with 35 receptions for 263 yards. He was an alternate in the 2002 Pro Bowl to starter Mike Alstott. He was also the Detroit Lions recipient of the 2002 Ed Block Courage Award.
Passage 3:DeGolyer opened a petroleum geology consultancy in 1914, moving to Montclair, New Jersey to work in New York City in 1916. In 1919, while working as a consultant to the British entrepreneur Lord Cowdray, DeGolyer negotiated the sale of the El Aguila company to Royal Dutch Shell. In the same year, DeGolyer organized the formation of the Rycade Oil Company as well as the Amerada Petroleum Corporation for Lord Cowdray, rising to become general manager, president, and chairman from 1929 to 1932 DeGolyer left the firm in 1932, but remained with Rycade, which was established to explore salt dome oil deposits through 1941. As a geophysical consultant with Rycade, DeGolyer made the first torsion balance survey in the United States at the Spindletop oilfield. An oilfield found by DeGolyer on behalf of Rycade at Nash, Texas was the first oilfield anywhere to be discovered using geophysics. From 1925 DeGolyer established the Geophysical Research Corporation as a subsidiary of Amerada to develop reflection seismology techniques originated by J. Clarence Karcher and Eugene McDermott, leaving in 1932 to move to Dallas, Texas. DeGolyer provided financial support for the 1930 establishment of GRC's successor, Geophysical Service Incorporated. GSI went on to spin off Texas Instruments. In 1936 with Lewis MacNaughton, DeGolyer established the petroleum exploration consulting firm DeGolyer and MacNaughton, and Core Laboratories, Incorporated the same year to provide drilling core and fluids analysis. DeGolyer was also associated with the Atlatl Royalty Company from 1932 to 1950 and the Felmont Corporation in 1934. In 1956 he established Isotopes, Incorporated to provide radioactive isotopes for oilfield and industrial purposes.

[EX Q]: Question: What country was Turnbull born in? Passage 1:Dinko Sakic (8 September 1921 20 July 2008) was a Croatian fascist leader and war criminal who commanded the Jasenovac concentration camp in the Independent State of Croatia (NDH) from April to November 1944, during World War II. Born in the village of Studenci, near the town of Imotski in what was then the Kingdom of Serbs, Croats and Slovenes, he became a member of the fascist Ustase at a young age. When the Axis powers occupied the Kingdom of Yugoslavia in April 1941, Sakic, aged 19, joined the administration in Jasenovac. He became the camp's assistant commander the following year, and married Nada Luburic, the half-sister of concentration camp commander Vjekoslav "Maks" Luburic, in 1943. This marriage, as well as his fanatic support for Ustase leader Ante Pavelic, led to Sakic's appointment as commander of Jasenovac in April 1944. He was charged in the deaths of an estimated 2,000 people who died during his six months of command at the concentration camp.
Passage 2:Mary was born the only child to David Turnbull (1900-1961), a native farm-owner in the Cheviot Hills, and Edna Mary Williamson (1901-1991), a schoolteacher from Laxey in the Isle of Man, on a farm not far from Wooler, Northumberland. In the 1920s Coventry grew to be the centre of UK motor industry, and her family moved to the thriving city when her father, who had been forced give up farming as a result of the Great Depression, found a job in motorcar engineering at the Rootes car factory. Throughout her childhood Mary led a happy but simple life despite having to live with different relatives during the Great Depression while her parents were both looking for work in Coventry, and being evacuated several times during World War II. She often described the experience of living through the Coventry Blitz and later, as a university student, the "doodlebugs" (V-1 flying bombs) in London.
Passage 3:Retford's officially designated BBC Local Radio station in terms of radio coverage is BBC Radio Sheffield.
