Input: Question: What martial arts does the man who Ken had a rivalry with after Jeff Jarrett participate in? Passage 1:U.S. Route 13 (US 13) is a U.S. highway running from Fayetteville, North Carolina north to Morrisville, Pennsylvania. In the U.S. state of Delaware, the route runs for . It traverses the entire length of the state from the Maryland state line in Delmar, Sussex County to the Pennsylvania state line in Claymont, New Castle County. US 13 connects many important cities and towns in Delaware, including Seaford, Dover, and Wilmington. The entire length of US 13 in Delaware is a multilane divided highway with the exceptions of the segment through Wilmington and parts of Philadelphia Pike in Claymont. Between the Maryland border and Dover, US 13 serves as one of the main north-south routes across the Delmarva Peninsula. From Dover north to the Wilmington area, the route is followed by the limited-access Delaware Route 1 (DE 1) toll road, which crosses the route several times and has multiple interchanges with it. US 13 bypasses downtown Wilmington to the east before it heads northeast of the city parallel to Interstate 495 (I-495) and the Delaware River to Claymont. US 13 is the longest numbered highway in the state of Delaware.
 Passage 2:After losing to Undertaker, Shamrock, Big Show, Mankind and Test formed The Union, a stable of wrestlers in opposition to the Corporate Ministry. The Union dissolved soon after defeating the Corporate Ministry at Over the Edge in May. Shamrock briefly feuded with Jeff Jarrett before beginning a rivalry with martial artist Steve Blackman that saw he and Blackman fight one another in a series of unorthodox matches. The feud ended at SummerSlam, where Shamrock defeated Blackman in a "Lion's Den weapons match". He went on to feud with the newly debuted Chris Jericho until departing the WWF in late 1999 in order to resume his mixed martial arts career. His departure was attributed on screen to an injury inflicted by Jericho's bodyguard, Mr. Hughes. Ken Shamrock has since appeared in the video games WWF SmackDown!,  (in Royal Rumble matches only), WWF No Mercy, WWE '13 and WWE 2K16.
 Passage 3:Constructed in 1930 for the 1932 Winter Olympics, the track was the first bobsleigh track located outside of Europe. In 1949, it hosted the FIBT World Championships, also the first outside of Europe. The original bobsleigh track was demolished in 1978 to pave the way for an artificial track for the 1980 Winter Olympics with a separate luge track being constructed for those same games. The luge track was the first luge track in North America when it was completed in 1979. In 1983, the luge track was the first venue to host the FIL World Luge Championships outside of Europe. Both tracks were demolished in the late 1990s and a combination track was constructed in early 2000 in time for the only Winter Goodwill Games. The track is a regular venue for World Cup competitions in bobsleigh, luge, and skeleton. In 2009, the track will become the first combination track to host the bobsleigh, luge, and skeleton world championships in a non-Winter Olympic year.
