question:
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:
Question: Who did Bruce Herschenohn run against in his primary? Passage:In 1992 four-term incumbent Democratic Senator Alan Cranston retired, creating an open seat contest. In what was billed as the "Year of the Woman", Boxer beat fellow Rep. Mel Levine and Lieutenant Governor Leo McCarthy in the Democratic primary, winning 44% of the vote. In the general election, Boxer defeated Republican Bruce Herschensohn, a conservative television political commentator from Los Angeles, by 4.9%. A last-minute revelation that Herschensohn had attended a strip club at least partially affected the outcome. In 1998, she won a second term, beating sitting California State Treasurer Matt Fong by 10.1% of the vote. After facing no primary opposition in the 2004 election, Boxer defeated GOP candidate Bill Jones, the former California Secretary of State, by 20%. In 2010, Boxer defeated GOP candidate Carly Fiorina, former chief executive officer of Hewlett-Packard, by 10%.

question:
Question: Who did the man who won this county in the 1924 election run against in that election? Passage:Along with adjacent Newton County, Searcy is unique among Arkansas counties in being traditionally Republican in political leanings even during the overwhelmingly Democratic "Solid South" era. This Republicanism resulted from their historical paucity of slaves, in turn created by infertile soils unsuitable for intensive cotton farming, and produced support for the Union during the Civil War. These were the only two counties in Arkansas to be won by Alf Landon in 1936, Wendell Willkie in 1940, Charles Evans Hughes in 1916, and even Calvin Coolidge in 1924. In Presidential elections post-1932, Harry S. Truman and Jimmy Carter are the only Democrats to carry the county. In the 1992 election George H. W. Bush won his second-highest margin in the state, and the Republican nominee has received over 60 percent in Presidential elections from 2000 to 2012 inclusive. In 2016, Searcy County voted over 79 percent for Donald Trump, while former Arkansas First Lady Hillary Clinton received just 16 percent.
