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: Travis Bickle, a 26-year-old honorably discharged U.S. Marine, is a lonely, depressed young man living in isolation in New York City. He takes a job as a taxi driver to cope with his chronic insomnia, driving passengers every night around the city's boroughs. He also frequents the porn theaters on 42nd Street and keeps a diary in which he consciously attempts to include aphorisms, such as "You're only as healthy as you feel."
Travis becomes infatuated with Betsy, a campaign volunteer for Senator and presidential candidate Charles Palantine. After watching her interact with fellow worker Tom through her window, Travis enters to volunteer, as a pretext to talk to her, and takes her out for coffee. On a later date, he naively takes her to see a pornographic film, which offends her, and she goes home alone. His attempts at reconciliation by sending flowers are rebuffed, so he berates her at the campaign office, before being kicked out by Tom.
Travis is disgusted by the sleaze, dysfunction, and prostitution that he witnesses throughout the city. His worldview is furthered when an adolescent prostitute and runaway, Iris, enters his taxi, attempting to escape her pimp, Sport. Sport drags Iris from the taxi and throws Travis a crumpled $20 bill, which continually reminds Travis of her and the corruption that surrounds him. A similarly influential event occurs when an unhinged passenger gloats to Travis of his intentions to murder his wife and her lover. Travis confides in fellow taxi driver Wizard about his thoughts, which are beginning to turn violent; however, Wizard assures him that he will be fine, leaving Travis to his own destructive path.
Question: What is the last name of the person that is told he will be fine by Wizard?
Bickle.

Passage: Three years after the destruction of the Death Star, the Rebel Alliance, led by Princess Leia, has set up a new base on the ice planet of Hoth. The Imperial fleet, led by Darth Vader, continues to hunt for the new Rebel base by dispatching probe droids across the galaxy. Luke Skywalker is captured by a wampa while investigating one such probe, but manages to escape from the wampa's lair with his lightsaber. Before Luke succumbs to hypothermic sleep, the Force ghost of his late mentor, Obi-Wan Kenobi, instructs him to go to Dagobah to train under Jedi Master Yoda. Han Solo locates Luke and cuts open the tauntaun he rode there on to keep his friend warm; they wait there until being rescued by a search party the next morning.
Meanwhile, the probe alerts the Imperial fleet to the Rebels' location. The Empire launches a large-scale attack using AT-AT walkers to capture the base, which forces the Rebels to retreat. Han and Leia escape with C-3PO and Chewbacca on the Millennium Falcon, but the ship's hyperdrive malfunctions. They hide in an asteroid field, where Han and Leia grow closer amidst tension and briefly kiss. Vader summons bounty hunters to assist in finding the Falcon. Luke, meanwhile, escapes with R2-D2 in his X-wing fighter and crash-lands on the swamp planet of Dagobah. He meets a diminutive creature who reveals himself to be Yoda; after conferring with Obi-Wan's spirit, Yoda reluctantly accepts Luke as his student.
Question: Who is told to go train under Yoda?
Luke.
