Example Input: Question: Which Major General served longer in the military, Wade Haislip or John Coulter? Passage:On 15 May 1942, five months after the United States entered World War II, the 85th Infantry Division was ordered into active military service at Camp Shelby, Mississippi, under the command of Major General Wade H. Haislip. Divisions in the U.S. Army at that time were "triangularized" with three combat regiments instead of the four regiment structure "square division" used during World War I. The 340th Infantry Regiment was redesignated as the 410th Quartermaster Battalion and left the division. Basic infantry training was begun in June 1942 at Camp Shelby, Mississippi. In April 1943, it participated in large-scale army training in the Louisiana Maneuvers near Leesville, Louisiana. In August, the division was moved to Camp Coxcomb, California for desert warfare training. In October, the division was transferred to Fort Dix, New Jersey, for final preparations before shipment overseas. Major General John B. Coulter was transferred as commander and retained this position throughout the war. The Assistant Division Commander (ADC) throughout the war was Brigadier General Lee S. Gerow.

Example Input: Question: What is the maximum depth of the water body where the Vistula river flows to its estuary? Passage:The Poles are the most numerous of the West Slavs and occupy what some believe to be the original homeland of the Slavic peoples. While other groups migrated, the Polanie remained in situ along the Vistula, from the river's sources to its estuary at the Baltic Sea. There is no other European nation centred to such an extent on one river. The establishment of a Polish state is often identified with the adoption of Christianity by Mieszko I in 966 CE (see Baptism of Poland), when the state covered territory similar to that of present-day Poland. In 1025 CE, Poland became a kingdom. In 1569, Poland cemented a long association with the Grand Duchy of Lithuania by signing the Union of Lublin, forming the Polish–Lithuanian Commonwealth. The Polish–Lithuanian Commonwealth was one of the largest and most populous countries in 16th- and 17th-century Europe.
