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: Which of the two Chicago Bulls player who were teammates on Detroit Pistons and won back-to-back titles had a longer tenure with the Pistons? Passage:The 1995–96 NBA season was the Bulls' 30th season in the National Basketball Association. During the offseason, the Bulls acquired rebound-specialist Dennis Rodman from the San Antonio Spurs, and signed free agent Randy Brown. Midway through the season, the team signed John Salley, who was released by the expansion Toronto Raptors. Salley won championships with the Detroit Pistons along with Rodman in 1989 and 1990. The 1996 Bulls is regarded to be the greatest Jordan team of the 90s and undoubtably of all time. This saw the Bulls set the record for most wins in an NBA regular season in which they won the championship, finishing with 72 wins and 10 losses. The regular season record was broken by the 2015–16 Golden State Warriors, who finished 73–9. The Warriors(2015-2016) have a connection to the (1995-1996) Bulls team, as Steve Kerr, the current Golden State coach, was a reserve point guard with the Bulls.

Example Input: Question: What was the New York giants regular season record the year Wally Pipp hit .296, and the Yankees lost to them that same year in the World Series? Passage:In 1918, Pipp hit only two home runs, but batted .304. He missed playing time under the nation's "work or fight" rule during World War I; he worked as a naval aviation cadet at the Massachusetts Institute of Technology. He batted .275 with seven home runs in 1919, as Babe Ruth surpassed him as the best power hitter in the American League. The Yankees moved to strengthen their team after the 1919 season, adding Ruth and fellow outfielder Bob Meusel and third baseman Joe Dugan. Between 1920 and 1924, Pipp had a .301 average, with season averages of 29 doubles, 94 runs scored, and 97 runs batted in (RBI) per season. Led by their strong lineup and additions to the pitching staff, such as Waite Hoyt, the Yankees finished in second place in 1920. Pipp became the cleanup hitter, behind Ruth in the batting order. Pipp hit .296 in 1921, and the Yankees won the American League pennant. However, they lost the 1921 World Series to the crosstown rival New York Giants of the National League.
