Example Input: Question: Who was the champion of Liga Alef that year when Hapel Nahriya F.C. was relegated to the fourth tier and never been back since? 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.
