Example Input: Question: How many times did Kurt Angle win the NWA Heavyweight Championship? Passage:The Impact World Championship is a professional wrestling world championship owned by the promotion Impact Wrestling, formerly Total Nonstop Action Wrestling (TNA). From June 2002 to May 2007, TNA used the NWA World Heavyweight Championship as their primary championship due to an agreement with the National Wrestling Alliance (NWA). On May 13, 2007, the NWA abruptly ended the arrangement and retrieved control of the NWA World Heavyweight Championship. On the same night, TNA were set to host their annual Sacrifice pay-per-view event, in which the NWA World Heavyweight Championship was to be defended by then-champion Christian Cage against Kurt Angle and Sting in a three-way match. Angle won the match and on the following episode of TNA's television program Impact! on May 17, was declared the new TNA World Heavyweight Champion. He was stripped of the championship later in the program, with Management Director Jim Cornette citing a problematic finish to the title match. The ownership of the championship was decided on June 17, 2007 at TNA's Slammiversary event in a King of the Mountain match involving Angle and Cage along with A.J. Styles, Chris Harris and Samoa Joe, which Angle won.
