[Q]: Passage: Audioslave's history dates back to October 18, 2000, when Rage Against the Machine's lead vocalist Zack de la Rocha announced he was leaving the band, citing a breakdown in its "decision-making process". Rage Against the Machine broke up as a result of de la Rocha's departure, but the remaining three members of the band—Tim Commerford, Tom Morello, and Brad Wilk—decided to stay together and announced plans to continue with a new vocalist. Several vocalists jammed with the three, including B-Real of Cypress Hill, but they did not want another rapper or anybody who sounded like de la Rocha. Contrary to popular belief, Layne Staley of Alice in Chains neither auditioned nor was asked to join the new project. Tom Morello denied this claim on his Twitter account in 2015. Music producer and friend Rick Rubin suggested that they play with Chris Cornell, the ex-frontman of Soundgarden. Rubin also persuaded the three of them to go into group therapy with performance coach Phil Towle after the breakup. Rubin was confident that with the right new voice, Rage Against the Machine had the potential to become a better band; he believed "it could turn into a Yardbirds-into-Led Zeppelin scenario." Commerford later credited Rubin for being the catalyst that brought Audioslave together. He called him "the angel at the crossroads" because "if it wasn't for him, I wouldn't be here today."The chemistry between Cornell and the other three was immediately apparent; as Morello described: "He stepped to the microphone and sang the song and I couldn't believe it. It didn't just sound good. It didn't sound great. It sounded transcendent. And...when there is an irreplaceable chemistry from the first moment, you can't deny it." The quartet wrote 21 songs during 19 days of rehearsal, and began working in the studio in late May 2001 with Rubin as producer, while sorting out the label and management issues. 
Question: What is the first name of the person Commerford credited with being the catalyst that brought Audioslave together?
[A]: Rick.


[Q]: Passage: Drake ended his studies at Cambridge nine months before graduation, and in autumn 1969 moved to London. His father remembered "writing him long letters, pointing out the disadvantages of going away from Cambridge ... a degree was a safety net, if you manage to get a degree, at least you have something to fall back on; his reply to that was that a safety net was the one thing he did not want." Drake spent his first few months in London drifting from place to place, occasionally staying at his sister's Kensington flat but usually sleeping on friends’ sofas and floors. Eventually, in an attempt to bring some stability and a telephone into Drake's life, Boyd organised and paid for a ground floor bedsit in Belsize Park, Camden.
On 5 August 1969, Drake recorded five songs for the BBC's John Peel show ("Cello Song", "Three Hours", "River Man", "Time of No Reply" and an early version of "Bryter Layter"), three of which were broadcast on the following night. A month later, on 24 September, he opened for Fairport Convention at the Royal Festival Hall in London, followed by appearances at folk clubs in Birmingham and Hull. Folk singer Michael Chapman said of the performances:The folkies did not take to him; [they] wanted songs with choruses. They completely missed the point. He didn't say a word the entire evening. It was actually quite painful to watch. I don't know what the audience expected, I mean, they must have known they weren't going to get sea-shanties and sing-alongs at a Nick Drake gig!
The experience reinforced Drake's decision to retreat from live appearances; the few concerts he did play around this time were usually brief, awkward, and poorly attended. Drake seemed reluctant to perform and rarely addressed his audience. As many of his songs were played in different tunings, he frequently paused to retune between numbers. 
Question: Where did the man who did not like to play in front of live audiences end his studies?
[A]: Cambridge.


[Q]: Passage: After John Dortmunder is released from his latest stint in prison, he is approached by his brother-in-law, Andy Kelp, about another job. Dr. Amusa seeks a valuable gem in the Brooklyn Museum that is of great significance to his people in his country in Africa, stolen during colonial times and then re-stolen by various African nations.
Dortmunder and Kelp are joined by driver Stan Murch and explosives expert Allan Greenberg, concocting an elaborate plan to steal the gem. Although the scheme (and each subsequent one) is carefully planned—and keeps increasing in cost—something always goes awry, and the quartet has to steal the diamond again and again.
First off, the diamond is swallowed by Greenberg when he alone gets caught by the museum guards during the initial heist. Dortmunder, Kelp, and Murch, at the urging of Greenberg's rotund father Abe, a lawyer, help Greenberg escape from state prison, but they then find he does not have the diamond. After Greenberg tells his partners he hid the rock in the police station (after bodily evacuating it), the quartet break into the precinct jail by helicopter, but the rock is not where Greenberg hid it. Greenberg discloses that his father Abe was the only other person who knew where it was.
It isn't until Murch, disguised as the grunting muscle man "Chicken," threatens Abe with being thrown down an elevator shaft, that Abe gives up the location of the diamond—his safe deposit box, and he also gives up the key to it.  However, Dortmunder cannot access the box because of bank vault security, and the gang leaves Abe in Dr. Amusa's office while they come up with a plan. 
Question: In who's office does the group leave the lawyer that stole the diamond?
[A]:
Dr. Amusa.
