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: Has the the team against which Duda hit three home runs on July 29 ever played in a World Series? Passage:On July 29, during a 7–3 loss to the San Diego Padres, Duda became the eleventh Mets player to hit three home runs in a single game, and only the second Met to do so at home after Kirk Nieuwenhuis had accomplished the feat less than a month before. Duda set a Mets franchise record on August 1 when eight of his consecutive hits came in the form of home runs; he and teammate Noah Syndergaard were named National League Co-Players of the Week for the week ending on August 2. On September 26, Duda hit his first career grand slam in the Mets' 10–2 victory over the Cincinnati Reds. That victory clinched the NL East division title for the New York Mets. On the final day of the season, Duda was hit by a pitch from the Washington Nationals' Tanner Roark, giving him 14 total HBP on the season and breaking the Mets single season record, previously shared by John Olerud and Ron Hunt. For the season, he had the highest fly ball percentage (50.6%), and the lowest ground ball percentage (27.4%), of all major league hitters.

Example Input: Question: How large was the GDP of Belfast the year Connolly station services were extended to that city? Passage:The station opened on 29 November 1844 by the Dublin and Drogheda Railway Company as Dublin Station, but was renamed Amiens Street Station ten years later after the street on which it is located. Originally the station served only a single mainline to Drogheda, and in 1853 through services to Belfast commenced. In 1891, the City of Dublin Junction Railway connected the station with Westland Row Station (now Pearse Station) on the city's South side. The City of Dublin Junction had a separate station known as Amiens Street Junction consisting of the present platforms 5, 6, and 7 (currently used by DART, Commuter and Rosslare services) with a separate street entrance. After the amalgamation of the GNR (I) at the end of the 1950s, this station became part of Amiens Street and the separate entrance fell into disuse. The City of Dublin Junction Railway allowed services to run from Amiens Street through to Westland Row to Rosslare and the South East. Services to Sligo were transferred to Westland Row (Pearse Station) running non-stop through the station in 1937, with the closure of Broadstone Station by CIÉ (see also MGWR). Services to Galway and Mayo also terminated at Westland Row, operating through Connolly Station after 1937, running via Mullingar and Athlone. This was discontinued in the 1970s in favour of running services from Heuston Station. Sunday trains to Cork, Limerick and Waterford during the 1960s operated from Connolly platforms 5, 6 and 7 through the Phoenix Park Tunnel, so as to avoid the cost of opening Heuston for the limited Sunday traffic demand at that time.
