Teacher: Now, understand the problem? If you are still confused, see the following example:
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-Lo 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 instance: Passage: Sheridan had her early vocal training while at school at the Dominican Convent in Eccles Street, Dublin, with additional lessons from Vincent O'Brien. In 1908, she won a gold medal at the Feis Ceoil. From 1909 to 1911 she studied at the Royal Academy of Music in London, during which time she was introduced to the Italian inventor Guglielmo Marconi, who was instrumental in arranging further studies for her in opera in Rome. With Marconi's help she auditioned in 1916 for Alfredo Martino, a prominent singing teacher attached to the Teatro Costanzi, and she made her debut there in January 1918 in Puccini's La Boheme. In July 1919 she appeared at the Royal Opera House (Covent Garden) in the title role in Iris by Pietro Mascagni. Sheridan returned to Italy, where her career continued to grow, with performances at the Teatro Dal Verme in Milan and at the Teatro San Carlo in Naples, primarily in Puccini roles. In 1922 she first sang at La Scala, Milan, in La Wally by Catalani under the direction of Toscanini. For the next few years she would sing at La Scala with great success. Perhaps her greatest role was Madama Butterfly, which she sang extensively in Italy and at Covent Garden. When she played the part of Madama Butterfly, Puccini was said to be spellbound.
