[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:Route 67 is mostly a two-lane surface road, with a divided four-lane section in Southbury. It begins in New Milford as a 0.5 mile concurrency with US 202 as the latter leaves a concurrency with US 7. After crossing the Housatonic River into the center of town, Route 67 breaks away to the southeast. In Bridgewater, it meets the northern end of Route 133. In Roxbury, it meets the southern end of Route 199 and the western end of Route 317. It then clips a corner of Woodbury before passing into New Haven County and the town of Southbury, where it passes the northern end of Route 172 before joining US 6 for a 4 lane divided 1.6 mile concurrency leading to a junction with I-84 at Exit 15. Here, US 6 joins I-84 West and Route 67 continues to the southeast becoming a 2-lane road once again. After intersecting Route 188, it enters Oxford, where it has a junction with the west end of Route 42. In Seymour, it passes the western end of Route 313 before crossing the Naugatuck River. On the east shore of the river, it meets the Route 8 expressway at Exits 21 & 22. It then passes the northern end of Route 115 before heading into Woodbridge, where Route 67 ends at Route 63.
Passage 3:Arsenal had finished the previous season as runners-up in the Premier League, overhauled by Manchester United in the final ten weeks of the season. The club did, however, retain the FA Cup, with a 10 win against Southampton. Such was Arsenal's effective start to the 200203 campaign, manager Arsene Wenger suggested his team could remain the whole season undefeated in all competitions:It's not impossible as A.C. Milan once did it but I can't see why it's so shocking to say it. Do you think Manchester United, Liverpool or Chelsea don't dream that as well? They're exactly the same. They just don't say it because they're scared to look ridiculous, but nobody is ridiculous in this job as we know anything can happen. The team lost to Everton a month after Wenger's proclamation; teenager Wayne Rooney scored the match winner, which ended a run of 30 league games without defeat. By February 2003, Arsenal moved five points clear of Manchester United at the top of the league table, but injuries to key players, not least captain Patrick Vieira, had destabilised the team. Draws in April, coupled with a defeat to Leeds United at home, mathematically ended Arsenal's chances of retaining the title. Wenger refuted opinions from the media that their season was a failure and said:

[EX Q]: Question: Which of the two characters that were additional features to Superman was introduced first? Passage 1:Fago was born in 1914 in Yonkers, New York, of parents who had immigrated from Naples, Italy. He had two sisters and a 10-year-older brother, Al Fago. At 14, Vincent Fago sold his first cartoon to the New York Sun, for $2. He attended DeWitt Clinton High School in the Bronx, graduating at age 20, he recalled in 2001, after encountering difficulties upon losing vision in one eye at age 16. By this time he had begun work as an animation tracer at Audio Productions in the old Edison studios in The Bronx, and advanced to become an in-betweener after the company moved to the Fox Movietone News Building. He then worked four years at the Jam Handy Studio in Detroit, Michigan, contributing, he said, to "films for Chevrolet, and stop-motion pictures, and Technicolor films for the Metropolitan Life Insurance Company. From there, he spent four years in Florida as an animator at Fleischer Brothers Studios, where he worked as an assistant animator on Betty Boop, Popeye and Supermantheatrical shorts and on the animated features Mr. Bug Goes to Town and Gulliver's Travels.
Passage 2:Gradually, the size of the issues was decreased as the publisher was reluctant to raise the cover price from the original 10 cents, so there were fewer stories. For a while, Congo Bill and Tommy Tomorrow were the two features in addition to Superman. Writer Robert Bernstein and artist Howard Sherman revamped the "Congo Bill" backup feature in issue #248 (January 1959) in a story wherein the character gained the ability to swap bodies with a gorilla and his strip was renamed Congorilla. The introduction of Supergirl by Otto Binder and Al Plastino occurred in issue #252 (May 1959). Following this debut appearance, Supergirl adopted the secret identity of an orphan "Linda Lee" and made Midvale Orphanage her base of operations. In Action Comics #261 (February 1960), her pet cat Streaky was introduced by Jerry Siegel and Jim Mooney. Supergirl joined the Legion of Super-Heroes in issue #276 and acted for three years as Superman's "secret weapon," until her existence was revealed in Action Comics #285 (January 1962). In the view of comics historian Les Daniels, artist Curt Swan became the definitive artist of Superman in the early 1960s with a "new look" to the character that replaced Wayne Boring's version. Bizarro World first appeared in the story "The World of Bizarros!" in issue #262 (April 1960). Writer Jim Shooter created the villain the Parasite in Action Comics #340 (Aug. 1966).
Passage 3:The islands of Africa can be subdivided into Indian Ocean Islands and Atlantic Ocean Islands. The largest number of islands of Africa are found in the Indian Ocean, with the sovereign island nations of Comoros, Seychelles, Mauritius and Madagascar located off the southeastern seaboard of Africa being the most notable. The French overseas territories of Mayotte and Reunion are also located nearby. The medium-sized islands of Zanzibar and Lamu of Tanzania and Kenya, respectively, are also located in the Indian Ocean, in addition to smaller islands off the coasts of other continental countries. In the Atlantic seaboard, the largest islands are Cape Verde off the coast of West Africa and Sao Tome and Principe off the southwestern seaboard. In the Atlantic Ocean, the island of Malabo and other smaller islands of Equatorial Guinea are also notable. The Canary Islands and other territories of Spain are present in the Mediterranean Sea in the north Atlantic Ocean, and the British possessions of Saint Helena, Ascension Island, and Tristan da Cunha are located off the southwestern seaboard of the continent.
