[EX Q]: Question: What state did the battle that Stanley lead an infantry division for the Army of the Mississippi take place? Passage:He fought at several battles in Missouri, including the Battle of Wilson's Creek, where he guarded the supply trains. President Abraham Lincoln appointed Stanley as brigadier general September 28, 1861, although the U.S. Senate did not confirm the appointment until March 7, 1862. Fighting in the Western Theater, he participated in the operations against New Madrid, Missouri and the Battle of Island Number Ten. He was involved in numerous major battles, including the Second Battle of Corinth, where he commanded a division of infantry of the Army of the Mississippi, and the Battle of Stones River, in which he led the cavalry of the Army of the Cumberland. On March 11, 1863, Stanley was appointed major general to rank from November 29, 1862. Stanley also led the Union cavalry in the Tullahoma Campaign. He fell ill late in 1863 and missed the Battle of Chickamauga. In 1864, he fought under William Tecumseh Sherman as a division commander in the IV Corps of the Army of the Cumberland during the Atlanta Campaign, and he was promoted to command of the corps when Maj. Gen. Oliver O. Howard was named commander of the Army of the Tennessee. After the capture of the city, instead of employing him marching to the sea, Sherman dispatched Stanley and his IV Corps to Tennessee to help protect the state from invasion by John Bell Hood's Army of Tennessee.

[EX Q]: Question: When was the place where the Cyclones play home games built? Passage:The 2011 Iowa State Cyclones football team represented Iowa State University in the 2011 NCAA Division I FBS football season. The Cyclones were led by third year head coach Paul Rhoads and play their home games at Jack Trice Stadium. They are a member of the Big 12 Conference. The conference play began with a loss at home to the Texas Longhorns, and ended with a loss at Manhattan, Kansas to the Kansas State Wildcats in the Farmageddon series, with a 36 record. The season will likely be remembered for the game against then #2 Oklahoma State Cowboys, who the Cyclones upset in a double-overtime thriller throwing the BCS into "utter chaos" as dubbed by sports media. The Iowa State squad was invited to the first Pinstripe Bowl game, which they were defeated by Rutgers, and the Cyclone's 2011 season came to a close with 67 overall record, 36 in Big 12 play, finished 8th place.

[EX Q]: Question: How old was Jock Nelson's father when his son was born? Passage:John Norman "Jock" Nelson (28 May 1908 20 June 1991) was an Australian politician. Born in Bundaberg, Queensland, he was the son of politician Harold Nelson. Jock Nelson was educated at state schools in Darwin before becoming a jackeroo and goldminer, and later a bore contractor at Alice Springs. After serving in the military from 1942 to 1945, he became a pastoralist. In 1949, he was elected to the Australian House of Representatives as the Labor member for Northern Territory, defeating the sitting independent, Adair Blain. At this time, the member for Northern Territory could only vote on matters relating to the Territory itself. In 1963, he was re-elected unopposed, the last occasion when a member was returned to the House of Representatives in this fashion. He retired in 1966, an occasion used by the Country Party to take the seat. Nelson returned to pastoralism and served as the first Mayor of Alice Springs (1971 - 1973) before he stepped down to become the Administrator of the Northern Territory (19731975) before his death in 1991.
