Task: Question Generation
Input (English): In the early decades of the twentieth century when there was a growing nostalgia for its sense of order, the style was revived and adapted and in the United States came to be known as the Colonial Revival. In Canada the United Empire Loyalists embraced Georgian architecture as a sign of their fealty to Britain, and the Georgian style was dominant in the country for most of the first half of the 19th century. The Grange, for example, a manor built in Toronto, was built in 1817. In Montreal, English born architect John Ostell worked on a significant number of remarkable constructions in the Georgian style such as the Old Montreal Custom House and the Grand séminaire de Montréal.
Output (English): What English born architect designed the Old Montreal Custom House?
