PROBLEM: Question: When was Kauffman Stadium built? Passage:At Kauffman Stadium, Dennis Leonard pitched a four-hit complete game to give the Royals a 2–1 series lead. After a one-out walk and single, Freddie Patek's RBI single off of Mike Torrez in the second put the Royas up 1–0. Next inning, Al Cowens's groundout with runners on second and third and no outs made it 2–0 Royals. The Yankees got on the board in the fifth when Graig Nettles singled with two outs and scored on Lou Pinella's double, but the Royals got that run back in the bottom of the inning when Hal McRae hit a leadoff double, moved to third on a groundout, and scored on Cowens's groundout. Next inning, Torrez allowed a leadoff walk and single, then got two outs before being relieved by Sparky Lyle, who allowed a two-run double to Amos Otis. Next inning, George Brett hit a leadoff single and scored on John Mayberry's RBI double.

PROBLEM: Question: How many teams were in the new Israeli second tier league when it was first created? Passage:Hapoel Nahariya spent 12 seasons in the second tier of Israeli football. They have reached the second tier for the first time in the 1953–54 season, where they placed fifth in the North division. In the following season, the club reached their best placing to date, after they finished third in Liga Alef North division. In the 1956–57 season they finished second bottom, and relegated to Liga Bet. The club returned to Liga Alef, after they finished third in the 1962–63 Liga Bet North A division, and relegated back to Liga Bet after another second bottom finish at the following season. Two seasons later, Hapoel won Liga Bet North A division, however, history repeated itself, and they were relegated in the following season (which was the "double season" of 1966–68), after yet another second bottom finish. In the 1969–70 season the club won Liga Bet North A division once again, and promoted to Liga Alef. This time, their return to Liga Alef was successful, as they finished the 1970–71 season in the fifth place in Liga Alef North, and remained in the second tier until 1976, when Liga Artzit was created and became the new second tier of Israeli football, whilst Liga Alef became the third tier. Hapoel played in Liga Alef until the 1981–82 season, when they finished bottom and relegated to Liga Bet. They did not return to the third tier of Israeli football ever since.
