Suppose The Great Fire of London was a major conflagration that swept through the central parts of London from Sunday, 2 September to Thursday, 6 September 1666. The fire gutted the medieval City of London inside the old Roman city wall. It threatened but did not reach the aristocratic district of Westminster, Charles II's Palace of Whitehall, and most of the suburban slums.
Can we infer that "The Great Fire of London was started intentionally by a group of arsonists."? Yes, no, or maybe?
