Input: Consider Input: Question: When was Ōe Tokihiro's father born? Passage:The first castle on this site dates to the middle of the Kamakura period. Ōe Tokihiro, the younger son of Ōe no Hiromoto, a senior retainer of the Kamakura shogunate was granted lands in Dewa Province, and in 1238 changed his name to Nagai Tokihiro. The Nagai continued to rule for about 150 years. The Nagai were supplanted in the Sengoku period by the Date clan, and the famed warlord Date Masamune was born at Yonezawa Castle. After Date Masamune defeated the Ashina clan in 1589, he moved his main castle to Kurokawa Castle in Aizu and put Date Munekiyo in charge of Yonezawa. However, Toyotomi Hideyoshi did not agree, and forced Masamune move back to Yonezawa. In 1591, Masamune relocated to Iwadeyama Castle by orders of Hideyoshi, surrendering Yonezawa Castle to Gamō Ujisato. When Ujisato’s son, Gamō Hideyuki was moved to Utsunomiya in 1597, the castle was turned over to Uesugi Kagekatsu, as part of their vast 1,200,000 koku holdings based in Aizu. The castellan at this time was Naoe Kanetsugu.

Input: Consider Input: Question: How long had Los Gatos been making music by the year La balsa was released? 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.
