TASK DEFINITION: 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.
PROBLEM: 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.
 Links: a. Data signaling rate b. Carrier wave c. Hertz d. Audio signal

PROBLEM: Question: How many different directors did Prada work with in 1976 and 1977? Passage:When Jaya Prada was a teenager, she performed a dance at her school's annual function. A film director in the audience offered her a three-minute dance number in the Telugu film Bhoomi Kosam. She was hesitant, but her family encouraged her to accept it. She was paid only 10 rupees for her work in the film, but the rushes of those three minutes of film were shown to the major figures of the Telugu film industry. Major filmmakers offered her starring roles in quality films, and she accepted them. She became a huge star in 1976 with major hit films. Director K. Balachander's black-and-white film Anthuleni Katha (1976) showcased her dramatic skills; K. Viswanath's color film Siri Siri Muvva (1976) showed her playing a mute girl with excellent dancing skills; and her title role as Sita in the big-budget mythological film Seetha Kalyanam confirmed her versatility. In 1977, she starred in Adavi Ramudu, which broke box office records and which permanently cemented her star status. The song "Aaresukoboyi Paresukunnanu" performed by Prada and co-star N.T. Rama Rao became a mass hit. Important filmmakers were casting her and repeating her in their films. Filmmaker Vijay introduced her to Kannada cinema in his 1977 super-hit movie Sanadi Appanna alongside Kannada matinee idol Raj Kumar. The movie is also known to be the only movie to feature shehnai rendition by Ustad Bismillah Khan. Jaya Prada repeated her successful pairing with Rajkumar in films such as Huliya Halina Mevu (1979), Kaviratna Kalidasa (1983) and Shabdavedhi (2000). In 1979, K. Balachander repeated her in the Tamil film Ninaithale Inikkum opposite Kamal Haasan and Rajinikanth in which she played a terminally-ill patient. She continued to act in more films in Telugu opposite actors such NTR, ANR, Krishna, Krishnam Raju and Sobhan Babu throughout the 70s and 80s. K. Viswanath remade Siri Siri Muvva (1976) in Hindi as Sargam, introducing Jayaprada to Bollywood in 1979. The film was successful and she became a star there as well. She earned her first Filmfare nomination as Best Actress but couldn't capitalize on her success since she couldn't speak Hindi.

PROBLEM: Question: What years did Cyrus the Great rule the Achaemenid Empire? Passage:Iran is home to one of the world's oldest continuous major civilizations, with historical and urban settlements dating back to 7000 BC. The south-western and western part of the Iranian Plateau participated in the traditional Ancient Near East with Elam, from the Early Bronze Age, and later with various other peoples, such as the Kassites, Mannaeans, and Gutians. Georg Wilhelm Friedrich Hegel calls the Persians the "first Historical People". The Medes unified Iran as a nation and empire in 625 BC. The Achaemenid Empire (550–330 BC), founded by Cyrus the Great, was the first true global superpower state and it ruled from the Balkans to North Africa and also Central Asia, spanning three continents, from their seat of power in Persis (Persepolis). It was the largest empire yet seen and the first world empire. The Achaemenid Empire was the only civilization in all of history to connect over 40% of the global population, accounting for approximately 49.4 million of the world's 112.4 million people in around 480 BC. They were succeeded by the Seleucid, Parthian, and Sasanian Empires, who successively governed Iran for almost 1,000 years and made Iran once again as a leading power in the world. Persia's arch-rival was the Roman Empire and its successor, the Byzantine Empire.
