Input: Consider Input: 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.

Input: Consider Input: Question: Is the driver who passed the pole-sitter ten laps into the race older than the drive he passed? Passage:Ten laps into the race, Michael Waltrip passed pole-sitter Jeff Gordon for the lead. On Lap 19, the caution flag was thrown after a multi-car accident. Waltrip continued leading until Lap 55, in which Dale Earnhardt Incorporated teammate Dale Earnhardt, Jr. After Bobby Hamilton, Jr. had an accident on Lap 70, Earnhardt led the race into pit road, but was pushed out by Gordon and Brian Vickers, and fell to fifteenth, giving Mike Wallace the lead entering Lap 74. Shepherd pitted on the following lap, and Morgan Shepherd took the lead. However, Shepherd would later pit, as Gordon regained the lead. Waltrip then retook the lead from Gordon on Lap 86, though Gordon then took the lead again 13 laps later. Ten laps later, Gordon pitted, and Waltrip was given the lead. On the ensuing lap, Earnhardt took the lead, though he later pitted, and Jimmy Spencer gained the lead. On Lap 113, Spencer lost the lead to Gordon when he pitted, who led the pit stops on Lap 139. Dave Blaney stayed out, and took the lead, though Ryan Newman gained first-place when Blaney went to pit road. Newman pitted on Lap 143, giving Tony Stewart the lead. With ten laps left in the race, Hendrick Motorsports teammates Jeff Gordon and Jimmie Johnson followed in third and fourth, respectively, behind Tony Stewart and Dale Earnhardt, Jr. Johnson then pushed Gordon past Stewart and Earnhardt, and Gordon subsequently won, his fourth of the season and second consecutive. The victory by Gordon made him the first driver since Cale Yarborough to win the Pepsi 400 from the pole. A version of the race's waning moments was included in the prologue of the video game , which involved Johnson pushing Gordon past Earnhardt.

Input: Consider Input: Question: In what state did the Lakers achieve a series opening 115-109 victory? Passage:The Lakers opened the series with a 115–109 victory at the Boston Garden. In Game 2, the Lakers led 113–111 with 18 seconds left when Gerald Henderson stole a James Worthy pass to score a game tying layup and the Celtics eventually prevailed in overtime 124–121. In Game 3, the Lakers raced to an easy 137–104 victory as Magic Johnson dished out 21 assists. After the game, Larry Bird said his team played like "sissies" in an attempt to light a fire under his teammates. In Game 4, the Lakers had a five-point game lead with less than a minute to play, but made several execution errors as the Celtics tied the game and then came away with a 129–125 victory in overtime. The game was also marked by Celtic forward Kevin McHale's takedown of Laker forward Kurt Rambis on a breakaway layup which triggered the physical aspect of the rivalry. Kareem Abdul-Jabbar would go after Larry Bird later on in the third quarter, and 1981 Finals MVP Cedric Maxwell further antagonized the Lakers by following a missed James Worthy free throw by crossing the lane with his hands around his own neck, symbolizing that Worthy was "choking" under pressure. In Game 5, the Celtics took a 3–2 series lead as Larry Bird scored 34 points. The game was known as the "Heat Game", as it was played under 97 °F-heat, and without any air conditioning at the infamous Boston Garden. In Game 6, the Lakers evened the series with a 119–108 victory. In the game, the Lakers answered the Celtics rough tactics when Worthy shoved Cedric Maxwell into a basket support. After the game, a Laker fan threw a beer at Celtics guard M.L. Carr as he left the floor, causing him to label the series "all-out-war." In Game 7, the Celtics were led by Cedric Maxwell, who had 24 points, eight rebounds, and eight assists as they came away with a 111–102 victory. In the game the Lakers rallied from a 14-point deficit to three points down with one minute remaining, when Maxwell knocked the ball away from Magic Johnson. Dennis Johnson responded by sinking two free throws to seal the Celtics' victory. Larry Bird was named MVP of the series.
