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: 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.

Example Input: Question: What is the current population of the town where Highway 28 has a junction with US Highway 71? Passage:The highway begins at Highway 28 in western Scott County within the Ouachita Mountains. Highway 28 runs southeast to Waldron, where it has a junction with US Highway 71 (US 71) on the city's west side. After this intersection, Highway 80 continues due east as a section line road and major east–west route in the city. An intersection with US Highway 71 Business (US 71B) just south of downtown Waldron gives access to the primary commercial areas of Waldron. Continuing east, the highway serves as the western terminus for Highway 248 just south of the Poteau River near the eastern city limits of Waldron. Just east of this junction, Highway 80 passes the Poteau Work Center owned and operated by the United States Forest Service. East of Waldron, Highway 80 enters the Ouachita National Forest, a dense pine and cypress forest. The route winds through the forest, serving as the eastern terminus of Highway 250 before entering Yell County.
