[Q]: Passage: In the original city plan, the interstate buses should also stop at the Central Station. Because of the growth of Brasília (and corresponding growth in the bus fleet), today the interstate buses leave from the older interstate station (called Rodoferroviária), located at the western end of the Eixo Monumental. The Central Bus Station also contains a main metro station. A new bus station was opened in July 2010. It is on Saída Sul (South Exit) near Parkshopping Mall and with its metro station, and it's also an inter-state bus station, used only to leave the Federal District. Question: Where is the older interstate bus station?
[A]: the western end of the Eixo Monumental


[Q]: Passage: The band had a number of bass players during this period who did not fit with the band's chemistry. It was not until February 1971 that they settled on John Deacon and began to rehearse for their first album. They recorded four of their own songs, "Liar", "Keep Yourself Alive", "The Night Comes Down" and "Jesus", for a demo tape; no record companies were interested. It was also around this time Freddie changed his surname to "Mercury", inspired by the line "Mother Mercury, look what they've done to me" in the song "My Fairy King". On 2 July 1971, Queen played their first show in the classic line-up of Mercury, May, Taylor and Deacon at a Surrey college outside London. Question: In what year did John Deacon join Queen?
[A]:
1971
