In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Passage: Much of the court martial testimony was critical of Bligh's conduct—by the time of his return to England in August 1793, following his successful conveyance of breadfruit to the West Indies aboard Providence, professional and public opinion had turned against him. He was snubbed at the Admiralty when he went to present his report, and was left on half pay for 19 months before receiving his next appointment. In late 1794 the jurist Edward Christian, brother of Fletcher, published his Appendix to the court martial proceedings, which was said by the press to "palliate the behaviour of Christian and the Mutineers, and to criminate Captain Bligh". Bligh's position was further undermined when the loyalist gunner Peckover confirmed that much of what was alleged in the Appendix was true.Bligh commanded HMS Director at the Battle of Camperdown in October 1797 and HMS Glatton in the Battle of Copenhagen in April 1801. In 1805 while commanding HMS Warrior, he was court-martialled for using bad language to his officers, and reprimanded. In 1806, he was appointed Governor of New South Wales in Australia; after two years a group of army officers arrested and deposed him in the Rum Rebellion. After his return to England, Bligh was promoted to rear-admiral in 1811 and vice-admiral in 1814, but was not offered further naval appointments. He died, aged 63, in December 1817.Of the pardoned mutineers, Heywood and Morrison returned to naval duty. Heywood acquired the patronage of Hood and, by 1803 at the age of 31, had achieved the rank of captain. After a distinguished career, he died in 1831. Morrison became a master gunner, and was eventually lost in 1807 when HMS Blenheim foundered in the Indian Ocean. Muspratt is believed to have worked as a naval steward before his death, in or before 1798. The other principal participants in the court martial—Fryer, Peckover, Coleman, McIntosh and others—generally vanished from the public eye after the closing of the procedures. 
Question: What is the last name of the person who died at 63?
Bligh.

Passage: Many recreational activities are available along the chain. The Mono Basin National Scenic Area visitor center is located near Mono Lake just off U.S. Route 395. A bookstore, an information desk staffed by USDA Forest Service Rangers, and museum exhibits help to orient visitors. The Mono Lake Committee has a staffed office and visitor information center in Lee Vining on the corner of U.S. Route 395 and 3rd Street. Information on camping, hiking, guided and self-guided tours can all be obtained at either location.
U.S. 395 is a scenic route that roughly parallels the Mono–Inyo Craters volcanic chain. California State Route 120 provides access to the northern and eastern parts of the Mono Domes, including Panum Crater. Mammoth Scenic Loop (also called Dry Creek Road), provides access to the Inyo Crater lakes and some of the Inyo domes.The town of Mammoth Lakes, located near the southern end of the chain and Mammoth Mountain, is the largest populated area nearby. Mammoth Mountain Ski Area is located nearby and gondola rides can be taken year-round (weather permitting) to the mountain's summit. The summit of Mammoth Mountain provides panoramic views of the craters and domes of the Mono–Inyo volcanic chain, Mono Lake, the Sierra Nevada and Long Valley Caldera.
Mono Lake itself has its own set of activities, including walking tours among towers of tufa, boat tours of the lake, and birdwatching opportunities. The lake is too salty to support any fish, but fishing is possible in streams that feed Mono Lake. Additional activities include hiking around and on the craters and domes, and mountain biking outside of the Scenic Area boundaries. 
Question: Information on camping, hiking, guided and self-guided tours can all be obtained at which locations?
an information desk.

Passage: In the years following his recuperation from the heart attack, Bowie reduced his musical output, making only one-off appearances on stage and in the studio. He sang in a duet of his 1971 song "Changes" with Butterfly Boucher for the 2004 animated film Shrek 2.During a relatively quiet 2005, he recorded the vocals for the song "(She Can) Do That", co-written with Brian Transeau, for the film Stealth. He returned to the stage on 8 September 2005, appearing with Arcade Fire for the US nationally televised event Fashion Rocks, and performed with the Canadian band for the second time a week later during the CMJ Music Marathon. He contributed backing vocals on TV on the Radio's song "Province" for their album Return to Cookie Mountain, made a commercial with Snoop Dogg for XM Satellite Radio and joined with Lou Reed on Danish alt-rockers Kashmir's 2005 album No Balance Palace.Bowie was awarded the Grammy Lifetime Achievement Award on 8 February 2006. In April, he announced, "I'm taking a year off—no touring, no albums." He made a surprise guest appearance at David Gilmour's 29 May concert at the Royal Albert Hall in London. The event was recorded, and a selection of songs on which he had contributed joint vocals were subsequently released. He performed again in November, alongside Alicia Keys, at the Black Ball, a benefit event for Keep a Child Alive at the Hammerstein Ballroom in New York. The performance marked the last time Bowie performed his music on stage.Bowie was chosen to curate the 2007 High Line Festival, selecting musicians and artists for the Manhattan event, including electronic pop duo AIR, surrealist photographer Claude Cahun, and English comedian Ricky Gervais. Bowie performed on Scarlett Johansson's 2008 album of Tom Waits covers, Anywhere I Lay My Head. On the 40th anniversary of the July 1969 moon landing—and Bowie's accompanying commercial breakthrough with "Space Oddity"—EMI released the individual tracks from the original eight-track studio recording of the song, in a 2009 contest inviting members of the public to create a remix. A Reality Tour, a double album of live material from the 2003 concert tour, was released in January 2010.In late March 2011, Toy, Bowie's previously unreleased album from 2001, was leaked onto the internet, containing material used for Heathen and most of its single B-sides, as well as unheard new versions of his early back catalogue. 
Question: What are the names of the people who sang a duet of the song "Changes" for the 2004 film Shrek 2?

Bowie.
