Example input: Passage: The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War. The war was fought between the colonies of British America and New France, with both sides supported by military units from their parent countries of Great Britain and France, as well as Native American allies. At the start of the war, the French North American colonies had a population of roughly 60,000 European settlers, compared with 2 million in the British North American colonies. The outnumbered French particularly depended on the Indians. Long in conflict, the metropole nations declared war on each other in 1756, escalating the war from a regional affair into an intercontinental conflict.
Example output: When was the French and Indian War?
Example explanation: This question is based on the following sentence in the passage- The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War.

You can ask questions like this one about dates, years, other numerals, persons, locations, noun phrases, verb phrases, adjectives, clauses etc. which exist in the paragraph.
Q: The main façade, built from red brick and Portland stone, stretches 720 feet (220 m) along Cromwell Gardens and was designed by Aston Webb after winning a competition in 1891 to extend the museum. Construction took place between 1899 and 1909. Stylistically it is a strange hybrid, although much of the detail belongs to the Renaissance there are medieval influences at work. The main entrance consisting of a series of shallow arches supported by slender columns and niches with twin doors separated by pier is Romanesque in form but Classical in detail. Likewise the tower above the main entrance has an open work crown surmounted by a statue of fame, a feature of late Gothic architecture and a feature common in Scotland, but the detail is Classical. The main windows to the galleries are also mullioned and transomed, again a Gothic feature, the top row of windows are interspersed with statues of many of the British artists whose work is displayed in the museum.
A:
Who designed the main façade that stretches along Cromwell Gardens?
