Question: At what age did Litto Nebbia write La balsa? 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.

Question: During which centuries were the Kyoto Imperial Palace and the Sento Imperial Palace home to the Emperors of Japan? Passage:With its 2,000 religious places – 1,600 Buddhist temples and 400 Shinto shrines, as well as palaces, gardens and architecture intact – it is one of the best preserved cities in Japan. Among the most famous temples in Japan are Kiyomizu-dera, a magnificent wooden temple supported by pillars off the slope of a mountain; Kinkaku-ji, the Temple of the Golden Pavilion; Ginkaku-ji, the Temple of the Silver Pavilion; and Ryōan-ji, famous for its rock garden. The Heian Jingū is a Shinto shrine, built in 1895, celebrating the Imperial family and commemorating the first and last emperors to reside in Kyoto. Three special sites have connections to the imperial family: the Kyoto Gyoen area including the Kyoto Imperial Palace and Sentō Imperial Palace, homes of the Emperors of Japan for many centuries; Katsura Imperial Villa, one of the nation's finest architectural treasures; and Shugaku-in Imperial Villa, one of its best Japanese gardens. In addition, the temple of Sennyu-ji houses the tombs of the emperors from Shijō to Kōmei.

Question: How many miles does the Red Line travel from its start at the Lambert St. Louis International Airport to the point where it meets up with the Blue Line? Passage:The Red Line MetroLink alignment begins at Lambert St. Louis International Airport, making stops at the main and east terminal stations. It then proceeds through Kinloch before making a stop in North Hanley near Bel-Ridge. It makes 2 stops (UMSL North & South stations) at the University of Missouri St. Louis located in Normandy. After departing UMSL-North Station, the trains divert south onto the former Wabash/Norfolk & Western Railroad's Union Depot (U.D.) line that once brought passenger trains from Ferguson to Union Station. It further follows into 2 stops in Pagedale on St. Charles Rock Road and Wellston on Plymouth St., before crossing the St. Louis City/County boundary line at Skinker Boulevard; and making a stop at Delmar Boulevard, serving the popular Delmar Loop and located just below the original Wabash Railroad's Delmar Station building. The Red Line meets up with the Blue Line at the Forest Park-DeBaliviere station. From this station to the Fairview Heights station in Illinois, it creates the Shared Alignment track with the Blue Line. It terminates in Shiloh next to the Scott Air Force Base and close to the Mid-America Airport in Mascoutah.
