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.

Input: Consider Input: Question: How many years after the Beach Boys released "Don't Worry Baby" did Roger Christian pass away? Passage:During a vocal tracking session in which Manson was singing over music already written for "Push It", the band felt that one of the lines in "Push It" would benefit from having a vocal chorus answering the words back to her. Inspired by Manson's spontaneous ad-lib of the phrase "don't worry baby" over the music, guitarist Steve Marker sampled the Beach Boys song "Don't Worry Baby" and used it as a backing vocal. The sample didn't work with what the band had already recorded so Manson re-sang the lines to fit the key and tempo of the song. Aware of the potential for incurring copyright legalities, the band debated whether or not to keep the line. Garbage and Brian Wilson coincidentally shared the same publishing company (Irving Music), and figuring that they had nothing to lose, contacted him through their company representative, sent him a copy of "Push It", and asked him for permission to use the interpolation. Wilson gave his blessing, and reportedly kept the tape. Both Wilson and Roger Christian, the deceased co-writer of "Don't Worry Baby", received a writing credit. A simpler interpolation credit was given to Herbie Azor, as the band's lawyers felt that there was a possible similarity of the line "Push it!" to his own "Push It", which had been a hit single for New York hip hop trio Salt-N-Pepa.

Input: Consider Input: Question: Which aircraft had a longer operational lifespan in the Royal Canadian Air Force between the McDonnell CF-101 Voodoo and the Avro CF-100 Canuck? Passage:The McDonnell CF-101 Voodoo was an all-weather interceptor aircraft operated by the Royal Canadian Air Force and the Canadian Forces between 1961 and 1984. They were manufactured by the McDonnell Aircraft Corporation of St. Louis, Missouri for the United States Air Force (as F-101s), and later sold to Canada. CF-101s replaced the obsolete Avro CF-100 Canuck in the RCAF's all-weather fighter squadrons. The Voodoo's primary armament was nuclear AIR-2A Genie unguided air-to-air rockets, and there was significant political controversy in Canada about their adoption. Although they never fired a weapon in wartime, the CF-101 served as Canada's primary means of air defence from Quick Reaction Alert facilities at Canadian airbases. The CF-101s were retired in the 1980s and replaced with McDonnell Douglas CF-18 Hornet fighters. Many examples are preserved in museums and parks in Canada and the United States.

Input: Consider Input: Question: Was Michael and Ralf Schumacher related? Passage:Specific attractions include the world's only complete collection of Vanwall cars, a near-complete collection of McLaren Formula One cars from the team's inception to the early 2000s, and extensive collections of Williams and BRM cars (including examples of both notorious BRM V16-powered machines as well as the H16-powered BRM P83). The collection also has examples of four different four-wheel drive Formula One cars, including an unraced Cosworth car. Another star exhibit is the Lotus 18 with which Stirling Moss won the 1961 Monaco Grand Prix, along with Jim Clark's World Championship-winning Lotus 25. Noticeable, however, is the distinct lack of Ferrari vehicles, 3 in all, but fine examples nonetheless. First being a Ferrari 312 driven by Chris Amon, second a 312B and thirdly, a Ferrari F2000 (The particular chassis driven to victory in the 2000 Canadian Grand Prix, one of nine victories for Michael Schumacher in his maiden championship winning series with Ferrari), conversely, the establishment houses the Jordan 191 in which he made his formula 1 debut in 1991. The 1998 Jordan 198, the most successful in Jordan's history, (the chassis being the one Damon Hill drove to victory in a 1-2 with team mate Ralf Schumacher at the 1998 Belgian Grand Prix at Spa Francorchamps) also figures. Another interesting exhibit is an Auto Union, built from pre-war plans following the factory's destruction by Allied bombing during World War II. Wheatcroft has also supplemented the racing car collection with some additional notable cars, including a replica of the personal Bugatti Royale of Ettore Bugatti.
