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.

Q: Question: What city did Mathews work in for Wrestlemania XXVII? Passage:In late 2010, Mathews often worked as the color commentator on Raw due to Jerry Lawler's increased in-ring competition. On April 3, 2011, Mathews commentated the majority of WrestleMania XXVII, though he received a 'Stone Cold Stunner' from an angered Stone Cold Steve Austin, cutting his night short. The following night on Raw, Mathews found himself aligned with Jerry Lawler, and against Michael Cole. He then became the alternate spokesman for the Anonymous Raw General Manager, when Michael Cole was not commentating. He then using the new catchphrase "The Anonymous Raw General Manager says...", before reading each e-mail. On the April 25 episode of Raw, Mathews announced that the Jim Ross and Jerry Lawler vs. Michael Cole and Jack Swagger match at Extreme Rules will be a Country Whipping match, which Cole and Swagger won. At the following pay-per-view, Over the Limit, Mathews supported Lawler, Bret Hart and Eve Torres in having Michael Cole kiss Lawler's foot. The following night, again as the spokesman for the anonymous Raw General Manager, Mathews read the e-mail that denied The Miz's request for another title shot, seemingly done with John Cena. He left the Raw broadcasting table the following week, after Cole and Lawler reconciled, though he remained on the show as a backstage interviewer and backup commentator.

Q: Question: In which country is the city where the Treaty of Wehlau was signed located? Passage:The Duchy of Prussia was a duchy in the eastern part of Prussia from 1525–1701. In 1525 during the Protestant Reformation, the Grand Master of the Teutonic Knights, Albert of Hohenzollern, secularized the Prussian State of the Teutonic Order, becoming Albert, Duke in Prussia. His duchy, which had its capital in Königsberg (Kaliningrad), was established as a fief of the Crown of Poland, as had been Teutonic Prussia since the Second Peace of Thorn in October 1466. This treaty had ended the War of the Cities or Thirteen Years' War and provided for the Order's cession of its rights over the western half of its territories to the Polish crown, which became the province of Royal Prussia, while the remaining part of the Order's land became a fief of the Kingdom of Poland (1385–1569). In the 17th century King John II Casimir of Poland submitted Frederick William to regain Prussian suzerainty in return for supporting Poland against Sweden. On July 29, 1657, they signed the Treaty of Wehlau in Wehlau (Polish: Welawa; now Znamensk), whereby Frederick William renounced a previous Swedish-Prussian alliance and John Casimir recognised Frederick William's full sovereignty over the Duchy of Prussia. Full sovereignty was a necessary prerequisite for upgrading the Duchy to Kingdom of Prussia in 1701.
