Input: Consider Input: Question: In what country did Boreal make his first appearance outside Germany? Passage:On his first race of 2002, Boreal made his first appearance outside Germany when he contested the Dubai Sheema Classic at Nad Al Sheba Racecourse on 23 March. Ridden by Kieren Fallon, he stayed on strongly in the straight and finished third behind Nayef and the New Zealand gelding Hades with the other beaten horses including Marienbard and Tobougg. On 7 June, the colt was sent to England and attempted to become the first German-trained horse to win the Coronation Cup over one and a half miles at Epsom Racecourse. Racing on soft ground, he started 4/1 third favourite behind Kutub (Preis von Europa, Gran Premio del Jockey Club, Singapore Gold Cup), and Storming Home. The other three runners were Marienbard, Zindabad (Yorkshire Cup), and Pawn Broker (Arc Trial). Fallon positioned the German challenger just behind the leader Zindabad before taking the lead entering the straight and tracking across to the stands-side (outside) rail. Boreal went clear of his rivals in the last quarter mile and won by three and a half lengths from Storming Home with Zindabad six lengths back in third. After training the first German winner at Group One level in Britain since Star Appeal took the 1975 Eclipse Stakes, Schiergen said, "He travels smoothly on good ground but is more at home on soft. It's a special thrill to have a winner in Britain, and extra-special when it's a Group 1 at the home of the Derby."

Input: Consider Input: Question: Of the two provinces to the east of Montreal, which has the largest land area? Passage:As a British colony, and with immigration no longer limited to members of the Roman Catholic religion, the city began to grow from British immigration. American Revolutionists under General Richard Montgomery briefly captured the city during the 1775 invasion of Canada but left when it became obvious they could not hold Canada. Often having suffered loss of property and personal attacks during hostilities, thousands of English-speaking Loyalists migrated to Canada from the American colonies during and after the American Revolution. In 1782, John Molson estimated the population of the city at 6,000. The government provided most with land, settling them in what became Upper Canada (Ontario) to the west, as well as Nova Scotia and New Brunswick to the east. The first Protestant church in Montreal was St. Gabriel's, established by a Presbyterian missionary in 1792. With 19th-century immigration, more and more English-speaking merchants and residents continued to arrive in what had by then become known as Montreal. Soon the main language of commerce in the city was English. The golden era of fur trading began in the city with the advent of the locally owned North West Company, the main rival to the primarily British Hudson's Bay Company. The first machine shop in Montreal, owned by one George Platt, was in operation before 1809. The census of 1821 numbered 18,767 residents.

Input: Consider Input: Question: What areas were affected by the tornado outbreak in 2008? Passage:A deadly tornado outbreak struck portions of the Lower Mississippi River Valley and the Southeastern United States on February 21–22, 1971. The two-day outbreak produced at least 19 tornadoes, and probably several more, mostly brief events in rural areas; killed 123 people across three states; and "virtually leveled" entire communities in the state of Mississippi. Three violent, long-lived tornadoes—two of which may have been tornado families—in western Mississippi and northeastern Louisiana caused most of the deaths along of path. One of the tornadoes attained F5 intensity in Louisiana, the only such event on record in the state. The outbreak also generated strong tornadoes from Texas to Ohio and North Carolina. The entire outbreak is the second deadliest ever in February, behind only the Enigma tornado outbreak in 1884 and ahead of the 2008 Super Tuesday tornado outbreak. February 21 was the fourth-deadliest day for tornadoes in Mississippi on record. At one point, the National Weather Service WSR-57 radar in Jackson, Mississippi, reported four hook echoes, often indicative of tornado-producing supercells, simultaneously.
