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: Where was the person born who directed Aeon Flux? Passage:The screenplay was written by Phil Hay and Matt Manfredi, and directed by Karyn Kusama. It was based on the animated TV series by Peter Chung, who had a minor role in this film version of his work. In the early stages of production, actress Michelle Rodriguez was considered for the part of Æon. She had previously worked with Kusama in Girlfight. Kusama had originally suggested filming in Brasília, the capital of Brazil, because the 20th-century modern architecture of that city fit with her vision of Bregna. The producers rejected the idea because Brasília lacked the infrastructure and technical expertise to support a major film production. After several cities were scouted, Berlin and Potsdam in Germany were chosen for filming. Berlin had several locations that fit into the organic yet structured world of Æon Flux. The crew gained permission to film in several locations that had never allowed such access before, including the Treptow Crematorium, the Adlershof Trudelturm and Windkanal wind tunnel facility, and the Haus der Kulturen der Welt ("House of the World's Cultures"). Additional locations included the Bauhaus Archive and a dissection theatre built in 1790 to train veterinarians, part of the Berlin animal shelter. It was used as the Handler space. Filming was temporarily suspended for a month during September 2004 while Theron recovered from a neck injury she sustained during stunt-work on the tenth day of shooting. She was hospitalized in Berlin for five days and required about six weeks of physiotherapy to recover.

Example Input: Question: How old is the producer of Viewtiful Joe? Passage:Viewtiful Joe is a 2.5D side-scrolling action-platformer, released on June 26, 2003. The title character is a parody of tokusatsu superheroes and is trying to save his girlfriend, who has been trapped in "Movieland" by a group of supervillains known as Jadow. To complete his quest, Joe must use his Viewtiful Effects Powers, which are based on camera tricks and special effects used in films. These include "Slow", which simulates bullet time; "Mach Speed", allowing Joe to attack all enemies with his afterimages; and "Zoom In", which triggers a camera close-up and unlocks special attacks. Internally, Capcom treated the game as a "staff-focused project" with the goal of increasing the skills of director Hideki Kamiya. The game achieved a Metacritic score of 93 and won GameCube Game of the Year awards from numerous publications including IGN, GMR, and USA Today. The game sold out its initial shipment of 100,000 to achieve a lifetime total of 275,000 units. Producer Atsushi Inaba considered the game a success, achieving his goals of training staff, keeping a small budget, and selling well. However, these numbers were lower than Capcom expected, prompting the publisher to port Viewtiful Joe to PlayStation 2 in 2004, with expanded features. This version sold 46,000 copies with a slightly lower Metacritic score of 90 owing to the lack of progressive scan and frame rate slowdown generated by the porting process.

Example Input: Question: Which of Vidal's first two plays was considered more successful? Passage:After publishing the plays Weekend (1968) and An Evening With Richard Nixon (1972) and the novel Two Sisters: A Novel in the Form of a Memoir (1970), Vidal concentrated upon the essay and developed two types of fiction. The first type is about American history, novels specifically about the nature of national politics. About those historical novels, the critic Harold Bloom said that "Vidal's imagination of American politics ... is so powerful as to compel awe". The historical novels formed the seven-book series, Narratives of Empire: (i) Burr (1973), (ii) 1876 (1976), (iii) Lincoln (1984), (iv) Empire (1987), (v) Hollywood (1990), (vi) Washington, D.C. (1967) and (vii) The Golden Age (2000). Besides U.S. history, Vidal also explored and analyzed the history of the ancient world, specifically the Axial Age (800–200 B.C.), with the novel Creation (1981). The novel was published without four chapters that were part of the manuscript he submitted to the publisher; years later, Vidal restored the chapters to the text and re-published the novel Creation in 2002.
