Question: Who designed Hans Klemm's first light aircraft? Passage:Hans Klemm's first light aircraft was the Daimler L15 and the L20 had much in common with it. Both were cantilever monoplanes with twin open, tandem cockpits and engines of very low power. The L20's low wing distinguished it from its predecessor and had the advantage of providing a low centre of gravity and better view during the landing approach as well as better protection for occupants in case of crash landings. The low-set wing also allowed a shorter undercarriage on the L20, which was otherwise like that of the L15 with the wheels independently mounted on pairs of centrally hinged V-struts and with vertical shock absorbing legs to the wing underside. Wheels were sometimes replaced by floats. Intended from the start for serial production, the L20's structure was simplified, with a pentagonal cross-section fuselage lacking the L15's rounded upper and lower surfaces. The fuselage was wooden framed with canvas covering. The overall strength of the structure, which had a safety factor of 12, was emphasised.

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.

Question: Who was the most recent winner of the game that the Cyclones lost to the Wildcats? Passage:The 2011 Iowa State Cyclones football team represented Iowa State University in the 2011 NCAA Division I FBS football season. The Cyclones were led by third year head coach Paul Rhoads and play their home games at Jack Trice Stadium. They are a member of the Big 12 Conference. The conference play began with a loss at home to the Texas Longhorns, and ended with a loss at Manhattan, Kansas to the Kansas State Wildcats in the Farmageddon series, with a 3–6 record. The season will likely be remembered for the game against then #2 Oklahoma State Cowboys, who the Cyclones upset in a double-overtime thriller throwing the BCS into "utter chaos" as dubbed by sports media. The Iowa State squad was invited to the first Pinstripe Bowl game, which they were defeated by Rutgers, and the Cyclone's 2011 season came to a close with 6–7 overall record, 3–6 in Big 12 play, finished 8th place.
