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,

Problem: Question: Which main composer did Rouvas work with for the creation of Kati Apo Mena? Passage:For his previous album, Irthes, Rouvas collaborated almost exclusively with Dimitris Kontopoulos, who was also commissioned to write all three of Rouvas' candidate songs for his participation in the Eurovision Song Contest 2009, as well as the composer and producer of his album, with the exception of one track. Working namely with one main composer is something that Rouvas had not done since Kati Apo Mena (1998) and not completely exclusively since Tora Arhizoun Ta Dyskola (1996). For Parafora, Rouvas reverted to using several songwriters and producers. The majority of the songwriters and producers are new collaborators and recent hit makers relatively new to the music industry. Kontopoulos, who first collaborated with Rouvas for To Hrono Stamatao (2003), resumed his role as a composer, producer, arranger, programmer, and instrumentalist, with eight contributions to the album, including the singles "Spase To Hrono" and the title track. Others who have never previously collaborated with Rouvas include Playmen, Beetkraft, Antonis Skokos, Greek-German Leonidas "Freakchild" Chantzaras, who composed "Nekros Okeanos" and produced "Emena Thes", and Dimitris Fakos who wrote both its music and lyrics. Songwriters who exclusively contributed lyrics to the album include Natalia Germanou, who first collaborated with Rouvas on Min Andistekese (1992), Pigi Konstantinou and Giannis Rentoumis who first collaborated with the artist on Irthes, and new collaborators Sunny Baltzi, Vagia Kalantzi, and Nikos Kostidakis, who wrote "Parafora".
