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 old was Anuradha Paudwal when she discovered Nikhil and Vinay and introduced them to Gulshan Kumar? Passage:Nikhil and Vinay are both trained in classical music. Singer Anuradha Paudwal discovered the duo and recommended them to Gulshan Kumar, owner of T-Series music company, and director Chandra Barot, who signed them for the 1991 romantic film Pyar Bhara Dil. The song "Banke Kitab Teri" from the film became popular. The duo then went on to compose music for over 20 films. Their initial successes included Bewafa Sanam (1995), a film which was breakthrough for playback singer Sonu Nigam, English Babu Desi Mem (1996), Uff Yeh Mohabbat (1997) and Papa The Great (2000). The duo composed music for two of Sonu Nigam's successful music albums, Jaan (1999) and Yaad (2001). They went on to score music for Anubhav Sinha's box office success Tum Bin which included hit songs such as "Koi Fariyaad", "Chhoti Choti Raatein" and "Tumhare Siva". Some of their other successful ventures include Hum Tumhare Hain Sanam, Aapko Pehle Bhi Kahin Dekha Hai, Muskaan and Kuch Dil Ne Kaha. The duo have also been accused of plagiarism by Pakistani singer Faisal Latif.

Input: Consider Input: Question: When was the man whose name is used as the unit of radio wave frequency born? Passage:A modulated radio wave, carrying an information signal, occupies a range of frequencies. See diagram. The information (modulation) in a radio signal is usually concentrated in narrow frequency bands called sidebands (SB) just above and below the carrier frequency. The width in hertz of the frequency range that the radio signal occupies, the highest frequency minus the lowest frequency, is called its bandwidth (BW). A given amount of bandwidth can carry the same amount of information (data rate in bits per second) regardless of where in the radio frequency spectrum it is located, so bandwidth is a measure of information-carrying capacity. The bandwidth required by a radio transmission depends on the data rate of the information (modulation signal) being sent, and the spectral efficiency of the modulation method used; how much data it can transmit in each kilohertz of bandwidth. Different types of information signals carried by radio have different data rates. For example, a television (video) signal has a greater data rate than an audio signal.

Input: Consider Input: Question: Is the actor who played Dodd from Massachusetts? Passage:An ensemble of 20 actors make up the bulk of the series' cast. Hawley found ensembles enticing because they presented "a lot of really good moving pieces". At Paleyfest 2015, the Fargo creator commented: "It's sort of like a horse race in a way, especially when you know that everyone is on this collision course. It's like, 'Who's going to make it?' And you can put people together in unexpected pairings." Offerman played Karl Weathers, an alcoholic and the only lawyer in Luverne, and Cristin Milioti was assigned the part of Betsy Solverson, Lou's terminally ill wife. Hawley felt that Milioti was the right choice because her personality was similar to her character's. Garrett portrays Joe Bulo, and Bokeem Woodbine appears as Mike Milligan, a role he was offered two days after auditioning. For the role of Hanzee Dent, Hawley hired Zahn McClarnon two weeks after his audition. Six others play members of the Gerhardts: Kieran Culkin as Rye, Rachel Keller as Simone, Michael Hogan as Otto, Allan Dobrescu as Charlie, Angus Sampson as Bear, and Jeffrey Donovan as Dodd. When asked about his decision to cast Donovan, Hawley told the actor, "I don't know. You just come off with a sense of power. I think Dodd comes off with a sense of power, and I thought that you have the chops to find the humor in it." Donovan gained 30 pounds in preparation for his role. Other major supporting roles in Fargo second season include: Bruce Campbell as Ronald Reagan, Keir O'Donnell as Ben Schmidt, and Elizabeth Marvel as Constance Heck.
