Question: How old was Harrison when he won the Presidency? Passage:Beginning with the 2000 election, the status of the Missouri bellwether came into question. Between 1904 and 2004, Missouri was carried by the victor of each presidential election, with the exception of 1956. Though Bush won the presidency in the 2000 election through the Electoral College, he lost the national popular vote. The 2000 election was unique because this was the first time in over a century where the popular vote winner lost the general election. (In 1888, Missouri voted for Grover Cleveland, the incumbent Democrat, who lost to Republican candidate Benjamin Harrison). Thus, controversy exists as to whether or not Missouri accurately predicted victor in this election. In the subsequent election, Missouri voted for George W. Bush, who this time won both the popular vote and the Electoral College. Missouri has voted reliably Republican since 2000. The state voted for John McCain in 2008, and for Mitt Romney in 2012, both of whom lost the general election to Barack Obama. The controversy is further complicated by the 2016 presidential election, where Missouri voted for Donald Trump by a landslide, while Hillary Clinton won the popular vote by nearly three million votes, but like in 2000, Trump won the Electoral College and became 45th President of the United States. Like 2000, political scientists have differing opinions on whether or not Missouri accurately predicted the victor, and even if Missouri is still a bellwether state at all.

Question: What was the population of Spoleto the first year that Raffaello de Banfield was Director of the ("Festival of the two worlds")? Passage:Raffaello de Banfield attended the Swiss International "Lyceum Alpinum Zuoz", the "Dante Alighieri" Lyceum in Trieste, the University of Bologna and the Benedetto Marcello Conservatory in Venice led by Gian Francesco Malipiero. He studied composition from 1946 to 1949 at the National Conservatory (under the direction of Henri Busser) with Nadia Boulanger in Paris. In these years he met Herbert von Karajan with whom he had a lifelong friendship, and also with artists such as Pablo Picasso, Jean Cocteau and Francis Poulenc. In the United States he belonged to the intellectual circle surrounding the writer and composer Paul Bowles, through which he met Tennessee Williams and Leonard Bernstein. In 1949 through the painter Leonor Fini he was introduced to the choreographer and ballet dancer Roland Petit; out of this grew the ballet Le combat ("The Duel"), which had its first original production in London in 1949. This piece, based upon the Tancred and Clorinda episode in Torquato Tasso's poem Gerusalemme liberata, was performed 39 times at the Vienna State Opera in the choreography of Dimitrije Parlic between 1959 and 1973. Until 1958 he spent time between Paris and New York and maintained a friendship also with Maria Callas. After years abroad in Italy, France, England and the United States, where he lived for more than ten years, he was from 1972 to 1996 Director of the Giuseppe Verdi Theatre in Trieste and he comprehensively renovated and modernised the Opera House. From 1978 to 1986 he was Director of the "" ("Festival of the two worlds") in Spoleto, Italy.

Question: Who did Avalanch replace Roberto Garcia with? Passage:Self-titled debut album WarCry was released on April 17, 2002. Guitarists Pablo García and Fernando Mon appeared only as guest musicians on the debut album, but became full-time members on 2002 along with keyboardist Manuel Ramil and bassist Alvaro Jardón. Second album El Sello De Los Tiempos was released on December 1, 2002. At the end of 2003, Jardón left the band due to musical and personal issues. On January 1, 2004 was released the third album Alea Jacta Est striking all the music stores around Spain. On the first concert of the tour supporting the album, the band presented Roberto García, formerly of Avalanch, as Jardón's replacement. Their fourth studio album, ¿Dónde Está La Luz?, was released on February 1, 2005, considered by critics "their heaviest album to date". They embarked on a supporting tour throughout Spain. WarCry played a sold-concert in Madrid. That performance was released on February 27, 2006 as a live album, named Directo A La Luz and soon was certified gold. La Quinta Esencia was their fifth album, released on September 18, 2006 with a great acceptance by the fans and the press, taking them to the highest positions on the Spanish charts. Sixth album was set to be released on May/June, 2008, but after the lineup changes they pushed it back to September, 2008. Víctor García stated that "this album will express much duality in human beings — good and evil."
