Input: Arena Football League
In 2014, the league announced the granting of a new franchise to former Mötley Crüe frontman Vince Neil, previously part-owner of the Jacksonville Sharks. That franchise, the Las Vegas Outlaws, were originally to play in Las Vegas at the MGM Grand Garden Arena in 2015, but instead played their home games at the Thomas & Mack Center, previous home to the Las Vegas Sting and Las Vegas Gladiators. After 20 years as a familiar name to the league, an AFL mainstay, the Iowa Barnstormers, departed the league to join the Indoor Football League. The San Antonio Talons folded on October 13, 2014, after the league (which owned the team) failed to find a new owner. On November 16, 2014, despite a successful season record-wise, the Pittsburgh Power became the second team to cease operations after the 2014 season. This resulted from poor attendance. It was later announced by the league that the Power would go dormant for 2015 and were looking for new ownership.

Along with the Las Vegas Gladiators, what prior AFL team played its home games at the Thomas & Mack Center?
Output: Las Vegas Sting

Input: United States dollar
The value of the U.S. dollar declined significantly during wartime, especially during the American Civil War, World War I, and World War II. The Federal Reserve, which was established in 1913, was designed to furnish an "elastic" currency subject to "substantial changes of quantity over short periods", which differed significantly from previous forms of high-powered money such as gold, national bank notes, and silver coins. Over the very long run, the prior gold standard kept prices stable—for instance, the price level and the value of the U.S. dollar in 1914 was not very different from the price level in the 1880s. The Federal Reserve initially succeeded in maintaining the value of the U.S. dollar and price stability, reversing the inflation caused by the First World War and stabilizing the value of the dollar during the 1920s, before presiding over a 30% deflation in U.S. prices in the 1930s.

What had previously kept prices stable?
Output: gold standard
