In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

[Q]: Passage: As The Five's campaign against Rubinstein continued in the press, Tchaikovsky found himself almost as much a target as his former teacher. Cui reviewed the performance of Tchaikovsky's graduation cantata and lambasted the composer as "utterly feeble.... If he had any talent at all ... it would surely at some point in the piece have broken free of the chains imposed by the Conservatory." The review's effect on the sensitive composer was devastating. Eventually, an uneasy truce developed as Tchaikovsky became friendly with Balakirev and eventually with the other four composers of the group. A working relationship between Balakirev and Tchaikovsky resulted in Romeo and Juliet. The Five's approval of this work was further followed by their enthusiasm for Tchaikovsky's Second Symphony. Subtitled the Little Russian (Little Russia was the term at that time for what is now called the Ukraine) for its use of Ukrainian folk songs, the symphony in its initial version also used several compositional devices similar to those used by the Five in their work. Stasov suggested the subject of Shakespeare's The Tempest to Tchaikovsky, who wrote a tone poem based on this subject. After a lapse of several years, Balakirev reentered Tchaikovsky's creative life; the result was Tchaikovsky's Manfred Symphony, composed to a program after Lord Byron originally written by Stasov and supplied by Balakirev. Overall, however, Tchaikovsky continued down an independent creative path, traveling a middle course between those of his nationalistic peers and the traditionalists.
[A]: What was the name of the group that approved of the work of Romeo and Juliet?


[Q]: Passage: From the time of his earliest recordings in the 1960s, Bowie employed a wide variety of musical styles. His early compositions and performances were strongly influenced by rock and rollers like Little Richard and Elvis Presley, and also the wider world of show business. He particularly strove to emulate the British musical theatre singer-songwriter and actor Anthony Newley, whose vocal style he frequently adopted, and made prominent use of for his 1967 debut release, David Bowie (to the disgust of Newley himself, who destroyed the copy he received from Bowie's publisher). Bowie's music hall fascination continued to surface sporadically alongside such diverse styles as hard rock and heavy metal, soul, psychedelic folk, and pop.Musicologist James Perone observes Bowie's use of octave switches for different repetitions of the same melody, exemplified in his commercial breakthrough single, "Space Oddity", and later in the song "Heroes", to dramatic effect; Perone notes that "in the lowest part of his vocal register ... his voice has an almost crooner-like richness."Voice instructor Jo Thompson describes Bowie's vocal vibrato technique as "particularly deliberate and distinctive". Schinder and Schwartz call him "a vocalist of extraordinary technical ability, able to pitch his singing to particular effect." Here, too, as in his stagecraft and songwriting, the singer's role playing is evident: historiographer Michael Campbell says that Bowie's lyrics "arrest our ear, without question. But Bowie continually shifts from person to person as he delivers them ... His voice changes dramatically from section to section." In a 2014 analysis of 77 "top" artists' vocal ranges, Bowie was 8th, just behind Christina Aguilera and just ahead of Paul McCartney. In addition to the guitar, Bowie also played a variety of keyboards, including piano, Mellotron, Chamberlin, and synthesizers; harmonica; alto and baritone saxophones; stylophone; viola; cello; koto (in the Heroes track "Moss Garden"); thumb piano; drums (on the Heathen track "Cactus"), and various percussion instruments.
[A]: What is the first name of the person who employed a wide variety of musical styles from the time of his earliest recordings?


[Q]: Passage: This portion of the quiet rural area was called Black Oak Ridge and was the northernmost of five principal oak- and pine-covered ridges around the meandering Clinch River. It was a verdant, beautiful countryside with rolling hills covered with dogwood and full of partridge and deer. To the east were the Great Smoky Mountains, to the west the peaks of the Cumberland Mountains.
The site was located in Roane County and Anderson County, and lay roughly halfway between the two county seats of Kingston and Clinton. Its greatest drawback was that a major road, Tennessee State Route 61, ran through it. Stone & Webster considered the possibility of re-routing the road. The Ohio River Division (ORD) of the Corps of Engineers estimated that it would cost $4.25 million to purchase the entire 83,000-acre (34,000 ha) site.
Groves became the director of the Manhattan Project on 23 September, with the rank of brigadier general. That afternoon, he took a train to Knoxville, where he met with Marshall. After touring the site, Groves concluded that the site "was an even better choice than I had anticipated". He called Colonel John J. O'Brien of the Corps of Engineers' Real Estate Branch, and told him to proceed with acquiring the land. The site was initially known as the Kingston Demolition Range; it officially became the Clinton Engineer Works (CEW) in January 1943, and was given the codename Site X. After the township was established in mid-1943, the name Oak Ridge was chosen from employee suggestions. It met with the Manhattan District's approval because "its rural connotation held outside curiosity to a minimum". Oak Ridge then became the site's postal address, but the site itself was not officially renamed Oak Ridge until 1947.
[A]:
What were the names of the two mountain ranges that were on either side of Black Oak Ridge?
