[EX Q]: Question: How many years did the Sacrifice pay-per-view-event happen? 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.

[EX Q]: Question: In which country did the Essex v Northamptonshire match take place? Passage:The Essex v Northamptonshire match was played at Valentines Park, Ilford 17 to 20 May. Northamptonshire won the toss and decided to bat, scoring 215 all out with a top score of 49 by Vince Broderick while Essex's Test leg break and googly bowler Peter Smith took four for 65. By close of play on Saturday, Essex had replied to 170 for 4 with opener Chick Cray on 90 not out. He completed his century, exactly 100, on Monday morning and Essex went on to total 267 all out. Northamptonshire were 219 for 5 at the close on Monday evening with their veteran batsman John Timms on 90 not out. Timms was out for 112 on Tuesday morning and Peter Smith completed ten in the match by taking six for 84 in the Northamptonshire total of 291. Essex therefore needed 240 to win with ample time left on the final day. They had a good stand of 103 for the fourth wicket between Frank Vigar (60) and Len Clark (64) but spinners Broderick and Bertie Clarke kept picking up the wickets and Essex were still ten behind when the ninth went down. The last pair were captain Tom Pearce and wicketkeeper Tom Wade who managed to level the scores before Wade was bowled by Clarke to tie the match.

[EX Q]: Question: Does South Australia have a lot of wetlands? Passage:The Coongie Lakes is a freshwater wetland system located in the Far North region of South Australia. The lakes system is located approximately north of the Adelaide city centre. The wetlands includes lakes, channels, billabongs, shallow floodplains, deltas, and interdune swamps. It lies on the floodplain of Cooper Creek, an ephemeral river flowing through a desert landscape in the Lake Eyre Basin which rarely, after occasional large floods, empties into Lake Eyre. The wetland system has been recognised both as being of international importance by designation under the Ramsar Convention with a listing on 15 June 1987 and being nationally important within Australia with a listing in A Directory of Important Wetlands in Australia (DIWA). Its extent includes the regional town of Innamincka, the Malkumba-Coongie Lakes National Park, the Innamincka Regional Reserve, the Strzelecki Regional Reserve and the Coongie Lakes Important Bird Area.
