[Q]: Passage: Sons of Soul bridged the gap between commercial and critical success for Tony! Toni! Toné!, helping them become one of the most popular acts in R&B at the time. Its success exemplified the genre's commercial resurgence during the early 1990s, when hip hop became the predominant African-American music genre in the mainstream. In 1994, Greg Kot of the Chicago Tribune attributed its resurgence to younger artists' blend of live instrumentation and hip hop production values, and cited Sons of Soul as "the most accomplished merger of hip-hop attitude with a '70s R&B aesthetic." The Atlanta Journal-Constitution hailed it as "a gentle reminder of those glory days" and felt that the group having both vocal and musical talents is most indicative of a return to early R&B's aesthetics. Furthermore, they garnered mainstream attention in a year of several high-profile controversies with R&B and hip hop artists such as Michael Jackson and Snoop Dogg. David W. Brown of The Harvard Crimson wrote that Tony! Toni! Toné! is "known primarily for the quality of its music, not its extracurricular reputation, unlike other groups such as Jodeci who rely on a playa-gangsta-mack image to sell-records."Along with acts such as Mint Condition and R. Kelly, Tony! Toni! Toné! played live instruments that complemented their hip hop sensibilities. Their concerts featured visual elements such as incense smoke and kaleidoscopic stage lighting, the group's eccentric wardrobe, and additional instrumentalists, including another guitarist, two drummers, two keyboardists, a violinist, a trumpeter, and a saxophonist. The Charlotte Observer remarked on the group in 1994: "[T]heir use of live instruments on record and onstage makes them an anomaly in the synthesized and sampled world of modern R&B." With the group's reliance on traditional soul and R&B values of songwriting and instrumentation, Sons of Soul was a precursor to the neo soul movement of the 1990s. Matt Weitz of The Dallas Morning News wrote in 1993 that the group had distinguished themselves from their New jack swing contemporaries with Sons of Soul and found them aesthetically akin to acts such as Prince and P.M. Dawn. Raphael Wiggins said of their success with the album:
"We've been very blessed to be able to be a group that writes our own songs and people have accepted us from both sides, hip hop and the R&B crowd or whatever you might want to say. I feel very fortunate to be able to do that here in 1993–94, because like you know, it was starting to be a dying thing that was happening. But I guess we were like the bridge between hip hop and soul and R&B, and being a little bit commercial also helped us. A lot of humor, a lot of nice slow songs and being able to play kind of brought us a foundation.". 
Question: What is the name of the group that Weitz said was aesthetically akin to acts such as Prince and P.M. Dawn?
[A]: Tony! Toni! Toné!.


[Q]: Passage: The second major American company to set up a manufacturing base in Trafford Park was the Ford Motor Company, in 1911. Initially Ford used its factory as an assembly plant for the Model T, although other vehicles were assembled there in later years, before moving to a new factory at Dagenham, Essex, in 1931. By 1915, 100 American companies had moved into the park, peaking at more than 200 by 1933. When the cotton industry began to decline in the early 20th century, Trafford Park and the Manchester Ship Canal helped Manchester – and to a lesser extent the rest of south Lancashire – to weather the economic depression from which the rest of Lancashire suffered. During the First World War the park was used for the manufacture of munitions, chemicals and other materiel. Most firms at Trafford Park succeeded in avoiding bankruptcy during the Great Depression, unlike the rest of Lancashire. Ford moved to Dagenham in 1931, but returned temporarily to Trafford Park during the Second World War.Metropolitan Vickers set up Manchester's and one of the UK's first radio stations at their factory in 1921. The station's first broadcast took place on 17 May 1922. In October that year the company was one of six who formed the British Broadcasting Company (BBC), which started broadcasting from the Metrovicks studio under the call sign 2ZY on 15 November 1922. Much of the station's content was musical, but news, plays, and children's programmes were also transmitted. Conditions in the small 30-by-16-foot (9.1 m × 4.9 m) studio were cramped, and the BBC moved the station to larger premises outside the park in 1923. 
Question: What was the place that peaked at more than 200 American companies by 1933?
[A]: Trafford Park.


[Q]: Passage: Olivier Eugène Prosper Charles Messiaen (French: [ɔlivje mɛsjɑ̃]; December 10, 1908 – April 27, 1992) was a French composer, organist, and ornithologist, one of the major composers of the 20th century. His music is rhythmically complex; harmonically and melodically he employs a system he called modes of limited transposition, which he abstracted from the systems of material generated by his early compositions and improvisations. He wrote music for chamber ensembles and orchestra, vocal music, as well as for solo organ and piano, and also experimented with the use of novel electronic instruments developed in Europe during his lifetime.
He travelled widely and wrote works inspired by diverse influences ranging from Japanese music, the landscape of Bryce Canyon in Utah and the life of St. Francis of Assisi. He said he perceived colours when he heard certain musical chords (a phenomenon known as synaesthesia in its literal manifestation); combinations of these colours, he said, were important in his compositional process. For a short period Messiaen experimented with the parametrisation associated with "total serialism", in which field he is often cited as an innovator. His style absorbed many global musical influences such as Indonesian gamelan (tuned percussion often features prominently in his orchestral works).
Messiaen entered the Paris Conservatoire at the age of 11 and was taught by Paul Dukas, Maurice Emmanuel, Charles-Marie Widor and Marcel Dupré, among others. He was appointed organist at the Église de la Sainte-Trinité, Paris, in 1931, a post held until his death. He taught at the Schola Cantorum de Paris during the 1930s. On the fall of France in 1940, Messiaen was made a prisoner of war, during which time he composed his Quatuor pour la fin du temps ("Quartet for the end of time") for the four available instruments—piano, violin, cello and clarinet. The piece was first performed by Messiaen and fellow prisoners for an audience of inmates and prison guards. He was appointed professor of harmony soon after his release in 1941, and professor of composition in 1966 at the Paris Conservatoire, positions he held until his retirement in 1978. His many distinguished pupils included  Iannis Xenakis, George Benjamin, Alexander Goehr, Pierre Boulez, Karlheinz Stockhausen, and Yvonne Loriod, who became his second wife.
He found birdsong fascinating, notating bird songs worldwide and incorporating birdsong transcriptions into his music. His innovative use of colour, his conception of the relationship between time and music, and his use of birdsong are among the features that make Messiaen's music distinctive. 
Question: In what year did the man who was born on December 10, 1908 retire from being a professor at the Paris Conservatoire?
[A]:
1978.
