[EX Q]: Question: Which of Shapovalov's opponents at Gatineau and Drummondville was younger? Passage:In March in Gatineau, Shapovalov captured his fourth ITF Futures singles title after defeating Gleb Sakharov in straight sets. Two weeks later, he won his first ATP Challenger title with a victory over Ruben Bemelmans at the 75K in Drummondville, and was the youngest Canadian to win a Challenger until Félix Auger-Aliassime's victory at the Open Sopra Steria de Lyon later in the year. The next week, he was defeated by Mirza Bašić in the final of the ATP Challenger 50K in Guadalajara, stopping his winning streak at 17 matches. At the French Open in May, his first professional Grand Slam, he was defeated in the first round of qualifying by the first seed Marius Copil in three sets. In June, Shapovalov qualified for the ATP 500 at the Queen's Club Championships, his fourth ATP main draw but his first as a qualifier. In the first round, he defeated his second top 50 player, world No. 47 Kyle Edmund, before losing to world No. 14 Tomáš Berdych. At Wimbledon in July, Shapovalov was awarded a wild card for the main draw. He was defeated by Jerzy Janowicz in the opening round. At the end of the month, he won his second ATP Challenger title, defeating compatriot Peter Polansky in the final of the 75K in Gatineau.

[EX Q]: Question: How old was the military engineer who scouted around Leith during the siege? Passage:The English King Henry VIII, angered by the Scots reneging on the initial agreement, made war on Scotland in 1544–1549, 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.

[EX Q]: Question: How many years had David Hamilton been a professional when he designed The Nelson Monument on Glasgow Green? Passage:Nelson became – and remains – Britain's greatest naval war hero, and an inspiration to the Royal Navy, yet his unorthodox tactics were seldom emulated by later generations. The first monument to be erected in Britain to commemorate Nelson may be that raised on Glasgow Green in 1806, albeit possibly preceded by a monument at Taynuilt, near Oban in Scotland dated 1805, both also commemorating the many Scots crew and captains at the battle. The Nelson Monument on Glasgow Green was designed by David Hamilton and paid for by public subscription. Around the base are the names of his major victories: Aboukir (1798), Copenhagen (1801) and Trafalgar (1805). The Nelson Monument overlooking Portsmouth was built in 1807–08 with money subscribed by sailors and marines who served at Trafalgar. In 1808, Nelson's Pillar was erected by leading members of the Anglo-Irish aristocracy in Dublin to commemorate Nelson and his achievements (between 10% and 20% of the sailors at Trafalgar had been from Ireland), and remained until it was destroyed in a bombing by "Old IRA" members in 1966. Nelson's Monument in Edinburgh was built between 1807 and 1815 in the form of an upturned telescope, and in 1853 a time ball was added which still drops at noon GMT to give a time signal to ships in Leith and the Firth of Forth. In summer this coincides with the one o'clock gun being fired. The Britannia Monument in Great Yarmouth was raised by 1819. Nelson's Column, Montreal began public subscriptions soon after news of the victory at Trafalgar arrived; the column was completed in the autumn of 1809 and still stands in Place Jacques Cartier.
