Input: Question: Is the Broad or Saluda river longer? Passage:The city is located approximately northwest of the geographic center of South Carolina, and is the primary city of the Midlands region of the state. It lies at the confluence of the Saluda River and the Broad River, which merge at Columbia to form the Congaree River. Columbia is home to the University of South Carolina, the state's flagship university and the largest in the state, and is also the site of Fort Jackson, the largest United States Army installation for Basic Combat Training. Columbia is also located 20 miles west of the site of McEntire Joint National Guard Base, which is operated by the U.S. Air Force and is used as a training base for the 169th Fighter Wing of The South Carolina Air National Guard. Columbia is also the location of the South Carolina State House, which is the center of government for the state. In 1860, the city was the location of the South Carolina Secession Convention, which marked the departure of the first state from the Union in the events leading up to the Civil War.
