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: How many teams are in the leagues which compete for the cup annually? Passage:In 2002, the International Ice Hockey Federation (IIHF) announced that it would acknowledge the site of Victoria Rink with "a commemorative plaque or other historical site marker to remind the passers-by of the existence of the Victoria Skating Rink, the birthplace of organized hockey." The commemoration has been marked in two ways. On May 22, 2008, a commemorative plaque was dedicated at the nearby Centre Bell, along with a plaque honouring James Creighton. Further, the IIHF created the Victoria Cup, a trophy named for the arena, for which—along with 1 million Swiss francs—one National Hockey League team and the champion of the European Champions Hockey League play-off annually. The first Cup match was held in Berne, Switzerland on October 1, 2008 between the New York Rangers and the Metallurg Magnitogorsk. The next, and last, edition of the Victoria Cup was held in Zurich on September 29, 2009, between the ZSC Lions and the Chicago Blackhawks.

He is a member of the New Democratic Party. Donnelly was first elected as a member of parliament in a by-election on November 9, 2009, in the New Westminster—Coquitlam electoral district.

Example Input: Question: When did Escobar start playing for the Royals? Passage:The Royals drew first blood in a back-and-forth opener that featured high offensive output from both teams. After hitting just three home runs in the regular season, Alcides Escobar hit a one-out homer to left to give the Royals a 1–0 lead. Later in the inning, with the bases loaded, Alex Gordon hit a broken bat, looping fly ball that dropped just fair inside the right-field line to plate all three runners. Suddenly, it was 4–0 Kansas City. Baltimore got a run back in the bottom of the inning on Adam Jones' RBI-single, but it could have been more had it not been for a great diving catch by Gordon in the left-center field gap, robbing Steven Pearce of a hit. In the bottom of the fifth, after the Royals added a run in the top of the frame, the Orioles finally got to James Shields. Nelson Cruz added to his postseason legacy with an RBI-double and Ryan Flaherty delivered a two-run single to make it a one-run game, 5–4. In the sixth, after a walk to Jonathan Schoop and a flare single to right by Nick Markakis, Alejandro De Aza hit a high chopper past the pitcher's mound that shortstop Escobar had no play on; Schoop scored to tie the game. Jones hit what appeared to be a double play ball, but Mike Moustaskas' relay throw short-hopped first baseman Eric Hosmer and the inning continued to bring up Cruz. He could not deliver the big hit this time as he rolled into an inning-ending double play.
