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: In what year did the wrestler who's neck the Godwinns tried to break begin his career? Passage:In 1996, Canterbury was reunited with Knight, who had been renamed Phineas I. Godwinn. The duo were portrayed as being cousins (later brothers) and were collectively known as "The Godwinns". The two were faces and were managed by Hillbilly Jim. They began to feud with the Body Donnas with Phineas having a crush on Sunny and signed her as their manager. They would beat the Body Donnas for the WWF Tag Team Championships. Eventually Sunny turned on them costing them their titles. The Godwinns feuded with the now heel Smoking Gunns, in losing efforts. In 1997, the Godwinns began a heel turn dropping Hillbilly Jim as a manager and picking up Uncle Cletus. The Godwinns quickly won the tag titles a second time from The Headbangers and began a heated feud with the Legion of Doom, which saw the team attempt to break Road Warrior Hawk's neck. They eventually dropped the titles to LOD in a match on WWF Monday Night Raw that had LOD's career on the line. Soon after that match they attacked and fired Cletus.

Example Input: Question: How many more games did the Cardinals win as compared with the Reds? Passage:Holding off fierce competition from the Cincinnati Reds and Pittsburgh Pirates, the Cardinals clinched the division crown as each team won at least 90 games. The Cardinals finished the season with an NL-best 97–65 won–loss record. They opened the playoffs by defeating the Pirates in five games in the NL Division Series (NLDS). Advancing to their third straight National League Championship Series, they defeated the Los Angeles Dodgers in six games for their 19th NL pennant. Rookie Michael Wacha, who had nearly no-hit the Washington Nationals late in September, continued his dominance throughout the postseason as he allowed no runs against the Dodgers in 13 IP, earning the NLCS MVP. It was the second straight NLCS appearance to which manager Mike Matheny guided the Cardinals, who became the first manager to appear in an LCS in his first two seasons. Rookie closer Trevor Rosenthal extended a 20-inning postseason scoreless streak that started in the 2012 NLDS. The Cardinals met the Boston Red Sox in the World Series, only to lose the series in six games.
