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.

Question: 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.

Question: Question: Who starred in Houston's first film? Passage:Houston took acting classes and received her first role in the 1975 made-for-television film Death Scream. In that same year Sheffield Lab released "I've Got the Music in Me" a Direct to disc recording by Thelma Houston and Pressure Cooker that went on to become a benchmark vinyl recording for audiophiles. The following year she recorded songs for the soundtrack of the film The Bingo Long Traveling All-Stars & Motor Kings starring Billy Dee Williams and James Earl Jones. In 1975 Houston appeared on the Golden Globe Award broadcast performing the nominated song "On & On" and also was featured in a tribute to Berry Gordy on that year's American Music Award broadcast singing "You've Made Me So Very Happy". That year Houston's version of "Do You Know Where You're Going To" was being set for single release when it was pulled and the song given to Diana Ross to serve as the theme song for the movie Mahogany. In 1976 Houston sang backing vocals for Motown labelmate Jermaine Jackson on his album My Name Is Jermaine.

Question: Question: What is the current age of the U.S. Army soldier who were held captive by the Taliban for five years? Passage:Serial is an investigative journalism podcast hosted by Sarah Koenig, narrating a nonfiction story over multiple episodes. The series was co-created and is co-produced by Koenig and Julie Snyder and developed by This American Life. Season one investigated the 1999 murder of Hae Min Lee (Hangul: 이해민), an 18-year-old student at Woodlawn High School in Baltimore. Season two focused on Sergeant Bowe Bergdahl, an American Army soldier who was held for five years by the Taliban, and then charged with desertion. Season three, which debuted in September 2018, explores cases within the Justice Center Complex in the Cleveland area. Serial ranked number one on iTunes even before its debut and remained there for several weeks. Serial won a Peabody Award in April 2015 for its innovative telling of a long-form nonfiction story. As of September 2018, episodes of seasons one and two have been downloaded over 340 million times, establishing an ongoing podcast world record.
