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-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: Question: How many years after the creation of Connacht did Saint Patrick travel through? Passage:Elphin has historically been an important market town and the diocesan centre for the Diocese of Elphin. St Patrick is believed to have visited Elphin, consecrated its first church and ordained its first bishop, Asicus (subsequently the patron saint of Elphin). Information supporting the visitation of St Patrick is to be found in two important memorials of early Irish hagiography, the Vita Tripartita of St Patrick, and the "Patrician Documents" in the Book of Armagh. On his missionary tour through Connacht in 434 or 435, St Patrick came to the territory of Corcoghlan, present day Elphin. The chief of that territory, a noble Druid named Ono, gave land and afterwards his castle or fort to St Patrick to found a church and monastery. The place, which had hitherto been called Emlagh-Ono (a derivation of its owners name) received the designation of Ail Finn, which means "rock of the clear spring". It derives from a story of St Patrick raising a large stone from a well opened by him in the land of Ono and placed on its margin. A copious stream of crystal water flowed from the well and continues to flow through Elphin to this day. St Patrick built a church called Tempull Phadruig (Patrick's church) and established an Episcopal See in Elphin. St Asicus remained as bishop of Elphin. St Patrick also founded an episcopal monastery or college at Elphin, believed to be one of the first monasteries founded by him. In pre-Reformation times, Elphin was host to a large number of religious orders and was a religious centre of international significance. This is supported by the appearance of Elphin in a number of pan-European maps in the Middle Ages.

Solution:
On his missionary tour through Connacht in 434 or 435, St Patrick came to the territory of Corcoghlan, present day Elphin
