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: 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.

Input: Consider Input: Question: Of the communities that Cromwell marched on after crossing the river Tweed, which has the largest population today? Passage:Meanwhile, the motto frappez fort, frappez vite (French, strike hard, strike fast) was carried out at once by the regular forces. On 19 July, Cromwell made the final arrangements at Berwick-on-Tweed. Major-General Thomas Harrison, a gallant soldier and an extreme English Independent, a Fifth Monarchist, was to command the regular and auxiliary forces left in England, and to secure the Commonwealth against Royalists and Presbyterians. Cromwell took with him Lieutenant-General Charles Fleetwood and Major-General John Lambert, and his forces numbered about 10,000 foot and 5,000 horse. His opponent David Leslie (his comrade of Marston Moor) had a much larger force, but its degree of training was inferior, it was more than tainted by the political dissensions of the people at large, and it was, in great part at any rate, raised by forced enlistment. On 22 July, Cromwell crossed the river Tweed. He marched on Edinburgh by the sea coast, through Dunbar, Haddington and Musselburgh, living almost entirely on supplies landed by the fleet which accompanied him, for the country itself was incapable of supporting even a small army, and on 29 July, he found Leslie's army drawn up and entrenched in a position extending from Leith to Edinburgh.
