One example: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lô during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,

Now, solve this: Question: How many opera's had Michael Arne written by the year Dignum launched his public career? Passage:Linley launched him on his public career in spring 1784, at first in the Handel memorial concerts at Westminster Abbey and the Pantheon, and then at Theatre Royal, Drury Lane, where he first appeared as Young Meadows in Love in a Village: 'His figure was rather unfavourable for the part, but his voice was so clear and full-toned, and his manner of singing so judicious, that he was received with great applause.' His next role was Cymon in Michael Arne's opera. In a busy first year he was well-received, appearing in various roles, and made his place alongside many well-established performers. 'On the removal of the elder Bannister to the Royalty Theatre, Dignum succeeded to a caste of parts more suited to his person and his voice, which was a fine tenor. Amongst other characters those of Hawthorn' (Love in a Village) 'and Giles' (The Maid of the Mill) (libretti by Isaac Bickerstaffe, 1762 and 1765 respectively) 'particularly suited him: indeed he was thought superior in them to any actor that had appeared since the days of John Beard, their original representative.' Dignum was the original performer of Crop the miller, in Stephen Storace's No song, no supper, and of Abdalla in Storace's Dido, Queen of Carthage. He was also well known as Tom Tug in Dibdin's The Waterman, in which role there is an illustration of him in the Garrick Club.
