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: When was the city where David was born established? Passage:Born into a poor family in Linlithgowshire in Scotland, Bartholomew joined the Merchant Navy at a young age and became a highly experienced sailor, travelling to the Baltic Sea and the West Indies, working on hired merchant ships during campaigns against French islands there at the outbreak of the French Revolutionary Wars. He later served on Greenland whalers, but in 1795 was seized by a press gang at Wapping and forcibly recruited into the Royal Navy. Due a superior education (although where he obtained this education is unknown), Bartholomew was rapidly promoted to midshipman, serving in numerous theatres and becoming a favourite of Admiral Sir Home Riggs Popham. Bartholomew was present at the surrender of the Dutch fleet in 1799, on HMS Romney in the East Indies and in 1802 was in charge of the ship's chronometers during a voyage to the Red Sea. The Peace of Amiens in the same year saw a reduction in the Navy and Bartholomew was placed in reserve.

Example Input: Question: How old was the Cardinals right fielder when he retired? Passage:The new season brought a Cardinals team that was much changed from the one that went 100-62 in 2005 but fell to the Houston Astros in the NLCS. Starting pitcher Matt Morris, second baseman Mark Grudzielanek, left fielder Reggie Sanders, and relief pitcher Julian Tavarez left the team via free agency. Relief pitcher Ray King was traded to Colorado. Right fielder Larry Walker retired. Brought in to replace the departed Cardinals were right fielder Juan Encarnacion, starting pitcher Sidney Ponson, relief pitchers Braden Looper and Ricardo Rincon, all via free agency, and second baseman Aaron Miles, acquired in the Ray King trade. Left field was left unsettled in the offseason and would remain so all year, with no player getting more than one-third of the playing time at that position.
Links: a. Julian Tavarez b. Larry Walker c. Reggie Sanders d. Larry Walker
Example Output: b

Example Input: Question: How many games did Higginbotham play for the team he ended his career with? Passage:He joined fellow Championship side Stoke City for a 225,000 fee in August 2006. He was made captain when Michael Duberry left in January 2007 and Stoke went on to narrowly miss out on a play-off place. With Stoke not being promoted Higginbotham again decided to hand in a transfer request to help force through a move to Sunderland. He spent one season at the Stadium of Light before returning to Stoke in 2008. He became a vital member of Tony Pulis' squad as Stoke established themselves in the Premier League. He scored the winning goal in the FA Cup quarter-final against West Ham United but missed out on both the semi-final and the final due to a knee injury. After his recovery he struggled to force his way back into the side and spent time out on loan to Nottingham Forest and Ipswich Town before joining Sheffield United on a free transfer in January 2013. After eight months at Bramall Lane, he left to join Conference Premier side Chester before ending his career with a short spell at Altrincham.
