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.

[EX Q]: 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 Julián Tavárez 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 Encarnación, starting pitcher Sidney Ponson, relief pitchers Braden Looper and Ricardo Rincón, 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.

[EX Q]: Question: How old was Sophie Okonedo the year that she appeared as Liz 10, in the episodes "The Beast Below" and "The Pandorica Opens"? Passage:Although Scream of the Shalka continues the narrative of the original 1963–89 programme and the 1996 television film, the show's 2005 revival ignored its events. The series was scripted by veteran Doctor Who writer Paul Cornell, with Richard E. Grant providing the voice for the Ninth Doctor. This performance followed years of rumours that Grant would play the Doctor in a film or new series, and indeed he had appeared as the "Conceited Doctor" in the Comic Relief special Doctor Who and the Curse of Fatal Death in 1999. Grant subsequently went on to appear in the revived television series of Doctor Who as a guest villain in 2012's "The Snowmen" and 2013's "The Bells of Saint John" and "The Name of the Doctor". The Doctor's companion for this adventure, Alison Cheney, was voiced by Sophie Okonedo who a year later would be nominated for an Academy Award for her performance in Hotel Rwanda. She also appeared in the 2010 series of Doctor Who, as Liz 10, in the episodes "The Beast Below" and "The Pandorica Opens". Derek Jacobi reprised his role as the Master in 2007's "Utopia". David Tennant appeared in a cameo role as the Caretaker, later being cast as the Tenth Doctor in 2005.

[EX Q]: Question: Did the close friend who inspired Kracaw to pursue psychology as her major enrolled in UC Berkeley the same year as she did? Passage:Kracaw graduated from high school in 1915. In the same year, her family left Colorado and moved to Orland, California, since the lower elevation there was expected to benefit her father's health. However, her father suffered setbacks in his business, and facing both blindness and tuberculosis, he committed suicide in 1917. Kracaw enrolled at the University of California, Berkeley, in 1915. She considered majoring in economics and English literature before deciding on psychology. She made a number of lifelong friends during her undergraduate years, including Jean Macfarlane, whose interest in psychology drove Kracaw to select that discipline for her major. She graduated cum laude in 1921, and began graduate study at UC Berkeley. Her Master's thesis studied ten families in San Francisco that had been clients of a juvenile court. She volunteered as a probation officer, and was required to meet and report on the families she was studying. She would later write that she struggled to be objective in writing about these families. Kracaw received her Master's degree in clinical psychology in 1920.
