Passage: Chrismansyah Rahadi ([xrismanah rahadi]; 16 September 1949 30 March 2007), born Christian Rahadi but better known by his stage name of Chrisye ([xri]), was an Indonesian progressive pop singer and songwriter. In his 40-year career he won many awards and accolades; in 2011 Rolling Stone Indonesia declared him the third-greatest Indonesian musician of all time.
Born in Jakarta of mixed Chinese-Indonesian descent, Chrisye became interested in music at an early age. At high school he played bass guitar in a band he formed with his brother, Joris. In the late 1960s he joined Sabda Nada (later Gipsy), a band led by his neighbours, the Nasutions. In 1973, after a short hiatus, he rejoined the band to play in New York for a year. He briefly returned to Indonesia and then went back to New York with another band, the Pro's. After once again returning to Indonesia, he collaborated with Gipsy and Guruh Sukarnoputra to record the 1976 indie album Guruh Gipsy.
Following the success of Guruh Gipsy, in 1977 Chrisye recorded two of his most critically acclaimed works: "Lilin-Lilin Kecil" by James F. Sundah, which eventually became his signature song, and the soundtrack album Badai Pasti Berlalu. Their success landed him a recording contract with Musica Studios, with whom he released his first solo album, Sabda Alam, in 1978. Over his almost 25-year career with Musica he recorded a further eighteen albums, and in 1980 acted in a film, Seindah Rembulan. Chrisye died in his Jakarta home on 30 March 2007 after a long battle with lung cancer.
Known for his stiff stage persona and smooth vocals, Chrisye was critically acclaimed in Indonesia. Five albums to which he contributed were included in Rolling Stone Indonesia's list of the 150 Best Indonesian Albums of All Time; another four of his songs (and a fifth to which he contributed) were classified as some of the best Indonesian songs of all time in a later issue of the same magazine. Several of his albums received certification of silver or gold. He received two lifetime achievement awards, one in 1993 from the BASF Awards and another posthumously in 2007 from Indonesian television station SCTV.
Question: What is the stage name of the person who joined Sabda Nada in the late 1960s?
Chrisye.

Passage: By the 18th century, the menagerie was open to the public; admission cost three half-pence or the supply of a cat or dog to be fed to the lions. By the end of the century, that had increased to 9 pence. A particularly famous inhabitant was Old Martin, a large grizzly bear given to George III by the Hudson's Bay Company in 1811. An 1800 inventory also listed a tiger, leopards, a hyena, a large baboon, various types of monkeys, wolves and "other animals". By 1822, however, the collection included only a grizzly bear, an elephant and some birds. Additional animals were then introduced. In 1828 there were over 280 representing at least 60 species as the new keeper Alfred Copps was actively acquiring animals.After the death of George IV in 1830, a decision was made to close down the Menagerie. In 1831, most of the stock was moved to the London Zoo which had opened in 1828. The last of the animals left in 1835, relocated to Regent's Park. This decision was made after an incident, although sources vary as to the specifics: either a lion was accused of biting a soldier, or a sailor, Ensign Seymour, had been bitten by a monkey. The Menagerie buildings were removed in 1852 but the Keeper of the Royal Menagerie was entitled to use the Lion Tower as a house for life. Consequently, even though the animals had long since left the building, the tower was not demolished until the death of Copps, the last keeper, in 1853.In 1999, physical evidence of lion cages was found, one being 2x3 metres (6.5x10 feet) in size, very small for a lion that can grow to be 2.5 meters (approximately 8 feet) long. In 2008, the skulls of two male Barbary lions (now extinct in the wild) from northwest Africa were found in the moat area of the Tower. Radiocarbon tests dated them from 12801385 and 14201480. During 2011 an exhibition was hosted at the Tower with fine wire sculptures by Kendra Haste.
Question: What was the last name of the last keeper who died in 1853?
Copps.

Passage: Will Rodman, a scientist at the San Francisco biotech company Gen-Sys, is testing the viral-based drug ALZ-112 on chimpanzees to find a cure for Alzheimer's disease. ALZ-112 is given to a chimp named Bright Eyes, greatly increasing her intelligence. But then, during Will's presentation for the drug, Bright Eyes is forced from her cage, goes on a rampage and is shot to death. Will's boss Steven Jacobs terminates the project and has the chimps slaughtered. However, Will's assistant Robert Franklin discovers that the reason for Bright Eyes' rampage was that she had recently given birth to an infant chimp. Will reluctantly agrees to take in the chimp, who is named Caesar. Will learns that Caesar has his mother's intelligence, through being exposed to ALZ-112 in her womb, and decides to raise him. Three years later, Will introduces Caesar to the redwood forest at Muir Woods National Monument. Meanwhile, Will treats his dementia-suffering father Charles with ALZ-112, which seems to restore his cognitive ability.
Question: What is the name of the infant chimp's mother?
Bright Eyes.
