Q: Passage: "Imagine" is a song co-written and performed by English musician John Lennon. The best-selling single of his solo career, its lyrics encourage the listener to imagine a world at peace without the barriers of borders or the divisions of religion and nationality and to consider the possibility that the whole of humanity would live unattached to material possessions. Shortly before his death, Lennon said that much of the song's "lyric and content" came from his wife Yoko Ono, and in 2017, she received a co-writing credit.Lennon and Ono co-produced the song and album of the same name with Phil Spector. Recording began at Lennon's home studio at Tittenhurst Park, England, in May 1971, with final overdubs taking place at the Record Plant, in New York City, during July. One month after the September release of the LP, Lennon released "Imagine" as a single in the United States; the song peaked at number three on the Billboard Hot 100 and the LP reached number one on the UK chart in November, later becoming the most commercially successful and critically acclaimed album of Lennon's solo career. Although not originally released as a single in the United Kingdom, it was released in 1975 to promote Shaved Fish, a compilation LP and it reached number six on the chart that year. The photograph on the cover was taken by May Pang in 1974. The song has since sold more than 1.6 million copies in the UK; it reached number one following Lennon's murder in December 1980. In 1985, the Central Park Conservancy memorialised a portion of the park in honour of Lennon, called Strawberry Fields, with a mosaic that reads "Imagine".BMI named "Imagine" one of the 100 most-performed songs of the 20th century. The song ranked number 30 on the Recording Industry Association of America's list of the 365 Songs of the Century bearing the most historical significance. It earned a Grammy Hall of Fame Award and an induction into the Rock and Roll Hall of Fame's 500 Songs that Shaped Rock and Roll. A UK survey conducted by the Guinness World Records British Hit Singles Book named it the second best single of all time, while Rolling Stone ranked it number three in their list of "The 500 Greatest Songs of All Time". Since 2005, event organisers have played it just before the New Year's Times Square Ball drops in New York City. Dozens of artists have performed or recorded versions of "Imagine", including Madonna, Stevie Wonder, Joan Baez, Lady Gaga, Elton John and Diana Ross. Emeli Sandé recorded a cover for the BBC to use during the end credits montage at the close of the 2012 Summer Olympics coverage in August 2012. "Imagine" subsequently re-entered the UK Top 40, reaching number 18. 
Question: What are the first names of the people who co-produced Imagine with Specter?

A: Yoko.

Q: Passage: Zappa's relationship with long-time manager Herb Cohen ended in 1976. Zappa sued Cohen for skimming more than he was allocated from DiscReet Records, as well as for signing acts of which Zappa did not approve. Cohen filed a lawsuit against Zappa in return, which froze the money Zappa and Cohen had gained from an out-of-court settlement with MGM over the rights of the early Mothers of Invention recordings. It also prevented Zappa having access to any of his previously recorded material during the trials. Zappa therefore took his personal master copies of the rock-oriented Zoot Allures (1976) directly to Warner Bros., thereby bypassing DiscReet.In the mid-1970s Zappa prepared material for Läther (pronounced "leather"), a four-LP project. Läther encapsulated all the aspects of Zappa's musical styles—rock tunes, orchestral works, complex instrumentals, and Zappa's own trademark distortion-drenched guitar solos. Wary of a quadruple-LP, Warner Bros. Records refused to release it. Zappa managed to get an agreement with Phonogram Inc., and test pressings were made targeted at a Halloween 1977 release, but Warner Bros. prevented the release by claiming rights over the material. Zappa responded by appearing on the Pasadena, California radio station KROQ, allowing them to broadcast Läther and encouraging listeners to make their own tape recordings. A lawsuit between Zappa and Warner Bros. followed, during which no Zappa material was released for more than a year. Eventually, Warner Bros. issued different versions of much of the Läther material in 1978 and 1979 as four individual albums (five full-length LPs) with limited promotion.Although Zappa eventually gained the rights to all his material created under the MGM and Warner Bros. contracts, the various lawsuits meant that for a period Zappa's only income came from touring, which he therefore did extensively in 1975–77 with relatively small, mainly rock-oriented, bands. Drummer Terry Bozzio became a regular band member, Napoleon Murphy Brock stayed on for a while, and original Mothers of Invention bassist Roy Estrada joined. Among other musicians were bassist Patrick O'Hearn, singer-guitarist Ray White and keyboardist/violinist Eddie Jobson. In December 1976, Zappa appeared as a featured musical guest on the NBC television show Saturday Night Live. Zappa's song "I'm the Slime" was performed with a voice-over by SNL booth announcer Don Pardo, who also introduced "Peaches En Regalia" on the same airing. In 1978, Zappa served both as host and musical act on the show, and as an actor in various sketches. The performances included an impromptu musical collaboration with cast member John Belushi during the instrumental piece "The Purple Lagoon". Belushi appeared as his Samurai Futaba character playing the tenor sax with Zappa conducting. 
Question: What is the first name of the person who prevented Zappa having access to any of his previously recorded material during the trials?

A: Herb.

Q: Passage: Forty-eight Non-Indian people visited Yosemite Valley in 1855, including San Francisco writer James Mason Hutchings and artist Thomas Ayres. Hutchings wrote an article about his experience that was published in the July 12, 1855, issue of the Mariposa Gazette and Ayres' sketch of Yosemite Falls was published in late 1855; four of his drawings were presented in the lead article of the July 1856 and initial issue of Hutchings' Illustrated California Magazine. The article and illustrations created tourist interest in Yosemite and eventually led to its protection.Ayres returned in 1856 and visited Tuolumne Meadows in the area's high country. His highly detailed angularly exaggerated artwork and his written accounts were distributed nationally and an art exhibition of his drawings was held in New York City.
Hutchings took photographer Charles Leander Weed to Yosemite Valley in 1859; Weed took the first photographs of the valley's features, which were presented to the public in a September exhibition held in San Francisco. Hutchings published four installments of "The Great Yo-semite Valley" from October 1859 to March 1860 in his magazine and re-published a collection of these articles in his Scenes of Wonder and Curiosity in California, which remained in print into the 1870s.
Carleton Watkins exhibited his 17 by 22 in (43 by 56 cm) Yosemite views at the 1867 Paris International Exposition.Photographer Ansel Adams made his first trip to Yosemite in 1916; his photographs of the valley made him famous in the 1920s and 1930s. Adams willed the originals of his Yosemite photos to the Yosemite Park Association, and visitors can still buy direct prints from his original negatives. The studio in which the prints are sold was established in 1902 by artist Harry Cassie Best.Milton and Houston Mann opened a toll road to Yosemite Valley in 1856, up the South Fork of the Merced River. They charged the then considerable sum of two dollars per person until the road was bought by Mariposa County, after which it became free.
In 1856, settler Galen Clark discovered the Mariposa Grove of giant sequoia at Wawona, an indigenous encampment in what is now the southwestern part of the park. Clark completed a bridge over the South Fork of the Merced River in 1857 at Wawona for traffic headed toward Yosemite Valley and provided a way station for travelers on the road the Mann brothers built to the valley.Simple lodgings, later called the Lower Hotel, were completed soon afterward; the Upper Hotel, later renamed Hutchings House and eventually known as Cedar Cottage, was opened in 1859. In 1876, the more substantial Wawona Hotel was built to serve tourists visiting the nearby grove of big trees and those on their way to Yosemite Valley. Aaron Harris opened the first campground business in Yosemite in 1876. 
Question: What are the first names of the two Mann brothers who built a road to Yosemite Valley on which Clark later provided a way station for travelers?

A:
Milton.
