Input: Consider Input: Question: How many President's children have lived in the White House? Passage:Within weeks, many Americans could recite favorite lines from the record, including "the rubber schwan [swan] is mine", and "move ahead...with great vigah [vigor]", the latter lampooning the President's own words. The album poked fun at Kennedy's PT-109 history; the rocking chairs he used for his painful back; the Kennedy clan's well-known athleticism, football games and family togetherness; children in the White House; and Jackie Kennedy's soft-spoken nature and her redecoration of the White House; and many other bits of knowledge that the public was eager to consume. Kennedy himself was said to have given copies of the albums as Christmas gifts, and once greeted a Democratic National Committee group by saying, "Vaughn Meader was busy tonight, so I came myself." According to UPI reporter Merriman Smith, during a Cabinet meeting Kennedy played the entire record for everyone. At one press conference, Kennedy was asked if the album had produced "annoyment (sic) or enjoyment." He jokingly responded, "I listened to Mr. Meader's record and, frankly, I thought it sounded more like Teddy than it did me. So, now he's annoyed."

Input: Consider Input: Question: Who was the second top scorer during the 1955-56 Serie A? Passage:Throughout his club career, Pivatelli most notably played for A.C. Milan (1961–63); he also played for Hellas Verona F.C. (1950–53), Bologna F.C. 1909 (1953–60), and S.S.C. Napoli (1960–61). After being dropped from the Inter Youth Side, Pivatelli was acquired by Verona in 1950, with whom he made his Serie B debut at the age of 17, scoring his first professional goal in his second appearance with the club, in a 4–1 victory over Vicenza. The following season, he was promoted to the starting line-up, and scored a total of 25 goals in 68 games for his team during the next three seasons, also helping the struggling club avoid relegation. After joining Bologna in 1953, he made his Serie A debut with the club on 13 September 1953, in a 2–1 home win over Atalanta. With the Emilian side, he was the Serie A top-scorer during the 1955–56 Serie A season, with 29 league goals in 30 appearances, and was the only Italian player to win the Capocannoniere title during the 1950s. In total, he scored 105 goals for Bologna during his seven seasons with the club. After playing with Napoli for the 1960–61 season, he joined Milan in 1961, and was part of the side that won the Serie A title in 1962, and the European Cup in 1963 under manager Nereo Rocco, after which he subsequently retired from playing professional football.

Input: Consider Input: Question: Where was the director of Triumph of the Will born? Passage:Triumph of the Will () is a 1935 Nazi propaganda film directed, produced, edited, and co-written by Leni Riefenstahl. It chronicles the 1934 Nazi Party Congress in Nuremberg, which was attended by more than 700,000 Nazi supporters. The film contains excerpts from speeches given by Nazi leaders at the Congress, including Adolf Hitler, Rudolf Hess and Julius Streicher, interspersed with footage of massed Sturmabteilung (SA) and Schutzstaffel (SS) troops and public reaction. Hitler commissioned the film and served as an unofficial executive producer; his name appears in the opening titles. The film's overriding theme is the return of Germany as a great power, with Hitler as the leader who will bring glory to the nation. Because the film was made after the 1934 Night of the Long Knives (on 30 June), many prominent Sturmabteilung (SA) members are absent—they were murdered in that Party purge, organised and orchestrated by Hitler to replace the SA with the Schutzstaffel (SS) as his main paramilitary force.
