In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Example Input: Question: What is the location of the headquarters for the company that makes 3M tape? Passage:Surgical tape or medical tape is a type of pressure-sensitive adhesive tape used in medicine and first aid to hold a bandage or other dressing onto a wound. These tapes usually have a hypoallergenic adhesive which is designed to hold firmly onto skin, dressing materials, and underlying layers of tape, but to remove easily without damaging the skin. They allow air to reach the skin ("breathable"). Some breathable tapes such as Kinesiology Tape, and other elastic bandages with adhesive are made of cotton. Surgical tape is often white because it contains zinc oxide, which is added to help prevent infections. Tapes made of microporous material, such as 3M Micropore, are widely used.

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.
