[EX Q]: Question: Which city had a greater population the year Gordon led his regiment to the Battle of Marks' Mills, Little Rock or Camden? Passage:In March and April 1864, Shelby's men harassed and skirmished with the Union Army force under the command of Major General Frederick Steele during his Camden Expedition, part of the Red River Campaign. Gordon led more than one charge against the Union forces during Steele's march from Little Rock to Camden, Arkansas. On April 25, 1864, Gordon led his regiment at the Battle of Marks' Mills where they captured two Union artillery pieces from the detachment of Union Lieutenant Colonel Francis M. Drake when Shelby's force attacked the Union left wing of the detachment which had been sent from Camden toward Pine Bluff, Arkansas to obtained supplies for Steele's force which was increasingly besieged by gathering Confederate forces at Camden. The Confederates outnumbered the Union force at Marks' Mills by more than 2 to 1 and overwhelmed it, taking about 1,300 prisoners and about 240 wagons. The overall commander of the Confederate cavalry force at Marks' Mills, Brigadier General James Fagan, led the Confederates, including Shelby's command, toward Pine Bluff in an effort to capture the Union supply depot. The Confederates did not make it to Pine Bluff due to flooding. They also did not return fast enough to cut off Steele's return march to Little Rock or to participate in the Battle of Jenkins' Ferry, the one big engagement during the retreat before the Union troops escaped across the swollen Saline River.

[EX Q]: Question: Which of the two writers of The American Band's greatest single was born first? Passage:The group was formed in Cicero, Illinois, United States, as Gary & The Knight Lites. The founding members included Gary Loizzo (vocals and guitar), Charles Colbert, Jr. (bass guitar and vocals), Al Ciner (guitar and vocals), and Jim Michalak (drums). Early releases included- "I'm Glad She's Mine," "I Don't Need Your Help," "Will You Go Steady," "Take Me Back," among others. The group's greatest success as "The American Breed" was the single, "Bend Me, Shape Me", which reached number five on the U.S. Billboard Hot 100 chart in 1968. The song, written by Scott English and Larry Weiss, had previously been recorded by an all-female band known as the Shape and had been a hit on the UK Singles Chart for the British group Amen Corner. It had also been recorded by The Outsiders after they had reached the top ten with "Time Won't Let Me" in 1966. Contributing to the success of the American Breed's version of "Bend Me, Shape Me" was the excellent arrangement of the song by the band's record producer, Bill Traut, who added horns among other changes. The group also appeared on the 16 December 1967 episode of the television show American Bandstand, along with Pink Floyd.
