[Q]: Passage: Zappa expressed opinions on censorship when he appeared on CNN's Crossfire TV series and debated issues with Washington Times commentator John Lofton in 1986. On September 19, 1985, Zappa testified before the United States Senate Commerce, Technology, and Transportation committee, attacking the Parents Music Resource Center or PMRC, a music organization co-founded by Tipper Gore, wife of then-senator Al Gore. The PMRC consisted of many wives of politicians, including the wives of five members of the committee, and was founded to address the issue of song lyrics with sexual or satanic content. During Zappa's testimony, he stated that there was a clear conflict of interest between the PMRC due to the relations of its founders to the politicians who were then trying to pass what he referred to as the "Blank Tape Tax." Kandy Stroud, a spokeswoman for the PMRC, announced that Senator Gore (who co-founded the committee) was a co-sponsor of that legislation. Zappa suggested that record labels were trying to get the bill passed quickly through committees, one of which was chaired by Senator Strom Thurmond, who was also affiliated with the PMRC. Zappa further pointed out that this committee was being used as a distraction from that bill being passed, which would lead only to the benefit of a select few in the music industry.Zappa saw their activities as on a path towards censorship, and called their proposal for voluntary labelling of records with explicit content "extortion" of the music industry.In his prepared statement, he said:
The PMRC proposal is an ill-conceived piece of nonsense which fails to deliver any real benefits to children, infringes the civil liberties of people who are not children, and promises to keep the courts busy for years dealing with the interpretational and enforcemental problems inherent in the proposal's design. It is my understanding that, in law, First Amendment issues are decided with a preference for the least restrictive alternative. In this context, the PMRC's demands are the equivalent of treating dandruff by decapitation. ... The establishment of a rating system, voluntary or otherwise, opens the door to an endless parade of moral quality control programs based on things certain Christians do not like. What if the next bunch of Washington wives demands a large yellow "J" on all material written or performed by Jews, in order to save helpless children from exposure to concealed Zionist doctrine?Zappa set excerpts from the PMRC hearings to Synclavier music in his composition "Porn Wars" on the 1985 album Frank Zappa Meets the Mothers of Prevention, and the full recording was released in 2010 as Congress Shall Make No Law... Zappa is heard interacting with Senators Fritz Hollings, Slade Gorton and Al Gore. 
Question: What is the first name of the person who saw the PMRC's activities as on a path towards censorship, and called their proposal for voluntary labelling of records with explicit content "extortion" of the music industry?
[A]: Frank.


[Q]: Passage: The Mozart family grand tour was a journey through western Europe, undertaken by Leopold Mozart, his wife Anna Maria, and their musically gifted children Maria Anna (Nannerl) and Wolfgang Amadeus from 1763 to 1766. At the start of the tour the children were aged eleven and seven respectively. Their extraordinary skills had been demonstrated during a visit to Vienna in 1762, when they had played before the Empress Maria Theresa at the Imperial Court. Sensing the social and pecuniary opportunities that might accrue from a prolonged trip embracing the capitals and main cultural centres of Europe, Leopold obtained an extended leave of absence from his post as deputy Kapellmeister to the Prince-Archbishopric of Salzburg. Throughout the subsequent tour, the children's Wunderkind status was confirmed as their precocious performances consistently amazed and gratified their audiences.
The first stage of the tour's itinerary took the family, via Munich and Frankfurt, to Brussels and then on to Paris where they stayed for five months. They then departed for London, where during a stay of more than a year Wolfgang made the acquaintance of some of the leading musicians of the day, heard much music, and composed his first symphonies. The family then moved on to the Netherlands, where the schedule of performances was interrupted by the illnesses of both children, although Wolfgang continued to compose prolifically. The homeward phase incorporated a second stop in Paris and a trip through Switzerland, before the family's return to Salzburg in November 1766.
The material rewards of the tour, though reportedly substantial, did not transform the family's lifestyle, and Leopold continued in the Prince-Archbishop's service. However, the journey enabled the children to experience to the full the cosmopolitan musical world, and gave them an outstanding education. In Wolfgang's case this would continue through further journeys in the following six years, prior to his appointment by the Prince-Archbishop as a court musician. 
Question: What location did the touring musician family return to at the end of the tour?
[A]: Salzburg.


[Q]: Passage: Richie Donovan works as a professional thief for Groznyi, a wealthy businessman, to pay off his debt for being smuggled into the U.S. as a child. He pulls off an initially successful diamond heist, but it is botched when he is involved in two separate car accidents. He is given one last chance to pay off his debt by going to Russia to steal a priceless antique cross, locked in a safe in a Moscow penthouse apartment. Richie and his Russian accomplices, brothers Peter and Yuri, recover the cross; but their elevator becomes stuck on the uncompleted 13th floor. Believing the police have stopped the elevator, the thieves take their fellow passengers hostage to negotiate an escape. They agree to send one hostage down; but, when the elevator doors open on the ground floor, the hostage has mysteriously been beheaded. 
The remaining hostages quickly divide into two groups: a Christian group consisting of Sonya, Helena and Katerina, who are later joined by Yuri, and another group consisting of nerdy Dmitry, beautiful Anna, and incompetent security guard Boris.
In the confusion, the Christian group seizes firearms and takes control, shooting Peter. Katerina is sent to stand guard over Richie and the remainder of the hostages, while Sonya takes Yuri to a chamber where he is to sacrificed by a wild man in armor named Alex. Yuri escapes, but he is impaled by one of Alex's traps, complete with disco music and lighting. In his rage, Alex kills Katerina, allowing Richie and the hostages to escape. They discover Alex's lair, where he has been watching everyone using security cameras. A photo reveals that Alex is the twin brother of Sonya, and they both believe themselves to be descendants of Ivan the Terrible. The group splits when Richie and Anna decide to chase after Alex, while Boris and Dmitry prefer to rig the room with various traps they have constructed and wait for Alex to come to them. 
Question: Who are the people who think the authorities are responsible for the elevator stopping, leading them to take hostages?
[A]:
Richie.
