Question: Passage: Half of Minneapolis–Saint Paul residents work in the city where they live. Most residents drive cars, but 60% of the 160,000 people working downtown commute by means other than a single person per auto. The Metropolitan Council's Metro Transit, which operates the light rail system and most of the city's buses, provides free travel vouchers through the Guaranteed Ride Home program to allay fears that commuters might otherwise be occasionally stranded if, for example, they work late hours.On January 1, 2011, the city's limit of 343 taxis was lifted.Minneapolis currently has two light rail lines and one commuter rail line. The METRO Blue Line LRT (formerly the Hiawatha Line) serves 34,000 riders daily and connects the Minneapolis–Saint Paul International Airport and Mall of America in Bloomington to downtown. Most of the line runs at surface level, although parts of the line run on elevated tracks (including the Franklin Avenue and Lake Street/Midtown stations) and approximately 2 miles (3.2 km) of the line runs underground, including the Lindbergh terminal subway station at the airport. 
Question: What is the former name of the line that has a terminal subway station at the airport?

Answer: Hiawatha Line.


Question: Passage: In 1986, Gilmour began recruiting musicians for what would become Pink Floyd's first album without Waters, A Momentary Lapse of Reason. There were legal obstacles to Wright's re-admittance to the band, but after a meeting in Hampstead, Pink Floyd invited Wright to participate in the coming sessions. Gilmour later stated that Wright's presence "would make us stronger legally and musically", and Pink Floyd employed him as a musician with weekly earnings of $11,000. Recording sessions began on Gilmour's houseboat, the Astoria, moored along the River Thames. Gilmour worked with several songwriters, including Eric Stewart and Roger McGough, eventually choosing Anthony Moore to write the album's lyrics. Gilmour would later admit that the project was difficult without Waters' creative direction. Mason, concerned that he was too out-of-practice to perform on the album, made use of session musicians to complete many of the drum parts. He instead busied himself with the album's sound effects.A Momentary Lapse of Reason was released in September 1987. Storm Thorgerson, whose creative input was absent from The Wall and The Final Cut, designed the album cover. To drive home that Waters had left the band, they included a group photograph on the inside cover, the first since Meddle. The album went straight to number three in the UK and the US. Waters commented: "I think it's facile, but a quite clever forgery ... The songs are poor in general ... [and] Gilmour's lyrics are third-rate." Although Gilmour initially viewed the album as a return to the band's top form, Wright disagreed, stating: "Roger's criticisms are fair. It's not a band album at all." Q Magazine described the album as essentially a Gilmour solo album.Waters attempted to subvert the Momentary Lapse of Reason tour by contacting promoters in the US and threatening to sue them if they used the Pink Floyd name. Gilmour and Mason funded the start-up costs with Mason using his Ferrari 250 GTO as collateral. Early rehearsals for the upcoming tour were chaotic, with Mason and Wright entirely out of practice. Realising he had taken on too much work, Gilmour asked Ezrin to assist them. As Pink Floyd toured North America, Waters' Radio K.A.O.S. tour was on occasion, close by, though in much smaller venues than those hosting his former band's performances. Waters issued a writ for copyright fees for the band's use of the flying pig. Pink Floyd responded by attaching a large set of male genitalia to its underside to distinguish it from Waters' design. The parties reached a legal agreement on 23 December; Mason and Gilmour retained the right to use the Pink Floyd name in perpetuity and Waters received exclusive rights to, among other things, The Wall. 
Question: What did the person who designed the flying pig get rights to in the 23 December legal agreement?

Answer: The Wall.


Question: Passage: It's Christmas Eve and Richie Rich, the world's richest kid, is all excited to spend the day with his friends. While racing wildly with his friends in the snow, Richie's butler, Herbert Cadbury, controls the cars using a remote and guides the children back to Richie's house. He then reminds him about his responsibilities that are due to be executed on Christmas Eve, and instructs him to change his clothes and get ready for tea. Before going to do so, he visits his home scientist, Professor Keanbean, who shows him his recent invention, a wishing machine which works only on Christmas Eve. The day being that, Richie wishes for a "big pie" from it, and is given a "pig sty" instead. Cadbury is disgusted seeing this, and sends him off to change his clothes. He meets his parents, Richard and Regina Rich, to ask what they would like to have for Christmas. While with them, he also tries out his father's new fishing rod invented by Keanbean, which hooks on to a tuna sandwich in the vicinity. He then goes on to change his clothes.
During tea, Richie meets his spoiled cousin, Reggie Van Dough, who wishes that he was as rich as Richie. Later, he dresses up like an elf with Cadbury as Santa Claus to distribute Christmas presents to the orphanage. While getting ready, Cadbury tells Richie about how he was a rock star in his youth days, in a band called Root Canal. When they take off in the sleigh with Richie driving it, Reggie takes control of it using the remote invented by Keanbean that Cadbury used earlier. He guides it through streets by shops, houses, and people, thus nearly destroying everything in the whole process. Richie and Cadbury end up in an accident in which the sleigh falls and literally explodes along with the presents, while Cadbury hurts his ankle badly. Richie runs off to fetch help, but once he enters the city, he sees that the situation has changed dramatically. Reggie is cooking up rumors about him, and all the people have turned against him. 
Question: What is the first name of the person that used to be a rock star?

Answer:
Herbert.
