Input: Consider Input: Question: How long had Juan Carlos Onganía been leading Argentina by the year La balsa was written? Passage:"La balsa" (; Spanish for "the raft") is the debut single by the Argentine band Los Gatos, released on July 3, 1967 on Vik, a subsidiary of RCA Victor. Formed in 1967 after the disbandment of Los Gatos Salvajes, Los Gatos were the house band of the bar La Cueva, which became a popular meeting place for rock enthusiasts and the birthplace of Argentine rock—known locally as rock nacional (Spanish for "national rock"). During the mid-to-late 1960s, Buenos Aires was experiencing a cultural blossoming characterized by innovations in modern art, literature and cinema, largely driven by a burgeoning youth subculture that adhered to the countercultural phenomenon of the decade. The underground had its center in La Cueva, Plaza Francia and the Torcuato di Tella Institute, and identified with British Invasion music and the sexual revolution. "La balsa" was written by Litto Nebbia—lead vocalist of the band—and Tanguito (credited as Ramsés) on May 2, 1967, in the men's toilet of La Perla de Once, another bar frequented by the group. At the time, Argentina was under a military dictatorship led by Juan Carlos Onganía, which regularly imprisoned and persecuted these young bohemians.

Input: Consider Input: Question: Who was the CEO of the company that Leaton got a paid internship with in 2006? Passage:He won significant critical attention in 2006 when he was awarded the grand prize of the 2006 Film Your Issue competition, judged by President Barack Obama, George Clooney and the Dalai Lama, among others. Leaton presented his winning film Orphans in Africa and gave acceptance speeches, covered by the press, at three awards ceremonies: at the United Nations Headquarters where he was introduced by the President of USA Today, then again in Hollywood where he was introduced by the Mayor of Los Angeles, and finally during Sundance in Park City with Kevin Bacon and Mandy Moore. Leaton also received the 2006 grand prize Walt Disney Pictures paid internship. His mentors included some of the top executives, and he began getting hands-on experience on various Disney films. Years later when Lindsey Brookbank of the Collegiate Times asked him what his favorite memory was from his grand-prize internship, he replied "Having dinner with Roy Disney on board the Queen Mary." According to Brookbank, this internship gave Leaton the connections and experience that would help him land jobs in Hollywood after finishing college. He returned to Film Your Issue as a member of the jury the following year, and has also judged other student film contests.

Input: Consider Input: Question: Where was Gyaltsen's father born? Passage:Ngawang Drakpa Gyaltsen was the son of Drowai Gonpo (1508–1548), a sub-ruler who resided in Gongri Karpo to the south-west of Lhasa. His grandfather was Ngawang Tashi Drakpa (1488–1564), the last effective king of the Phagmodrupa line. The main palace of the dynasty was Nêdong southeast of Lhasa. In 1554 Ngawang Drakpa Gyaltsen temporarily took over the throne of his old grandfather, when the latter was forced to step down for a while. However, new turmoil broke out in Central Tibet in 1555. A council was headed by the religious hierarchs of Drigung Kagyu and Shamarpa, and it was decided to put the old ex-king back on the throne. Ngawang Drakpa Gyaltsen had to return to Gongri Karpo. Some years later he rose against the 75-year-old ruler and tried to acquire the throne permanently. He was aided in his ambitions by the ruler of Ganden. He also kept good relations with Sonam Gyatso, later known as the Third Dalai Lama. A number of Buddhist dignitaries tried to intervene in the rebellion, to no avail. In the next year 1564, his grandfather died. New disturbances broke out between the Nêdong and Gongri Karpo branches of the dynasty. Sonam Gyatso was asked to mediate in the conflict. Eventually Ngawang Drakpa Gyaltsen became the new gongma or king in 1576. However, the executive authority of the Phagmodrupa was now almost depleted. Nevertheless, the Phagmodrupa still filled a role as a focal point around which politics in Ü (East Central Tibet) revolved and different groups balanced each other. Conditions in this part of Tibet tended to be relatively peaceful in the decades of the late sixteenth century, and relations between the main religious sects Karmapa and Gelugpa were amiable for the moment.
