Question: Question: What were the combined ages of Joseph Urban and Benjamin Wistar Morris the year that they were both hired to come up with blueprints for the house? Passage:The construction of Rockefeller Center occurred between 1932 and 1940 on land that John D. Rockefeller Jr. leased from Columbia University. The Rockefeller Center site was originally supposed to be occupied by a new opera house for the Metropolitan Opera. By 1928, Benjamin Wistar Morris and designer Joseph Urban were hired to come up with blueprints for the house. However, the new building was too expensive for the opera to fund by itself, and it needed an endowment, and the project ultimately gained the support of John D. Rockefeller Jr. The planned opera house was canceled in December 1929 due to various issues, with the new opera house eventually being built at Lincoln Center, opening in 1966.

Question: Question: Which countries comprised the alliance that conquered and occupied Greece? Passage:Aside from the Romaniotes, a distinct Jewish population that historically lived in communities throughout Greece and neighboring areas with large Greek populations, Greece had a large population of Sephardi Jews, and is a historical center of Sephardic life; the city of Salonica or Thessaloniki, in Greek Macedonia, was called the "Mother of Israel". Greek Jews played an important role in the early development of Christianity, and became a source of education and commerce for the Byzantine Empire and throughout the period of Ottoman Greece, until suffering devastation in the Holocaust after Greece was conquered and occupied by the Axis powers despite efforts by Greeks to protect them. In the aftermath of the Holocaust, a large percentage of the surviving community emigrated to Israel or the United States.

Question: Question: When was the song from which the chorus for Fire Water Burn was taken first released? Passage:To create the hip-hop and rock fusions on the album, Jimmy Pop utilized the standard hip hop technique of sampling. The chorus for "Fire Water Burn" is taken from "The Roof Is on Fire" by Rock Master Scott & the Dynamic Three and also features the lyrics 'I am white like Frank Black is / So if man is five and the devil is six then that must make me seven / This honkey's gone to heaven,' a direct reference to the post-1993 stage name of Black Francis who wrote the Pixies song "Monkey Gone to Heaven" to which the lyrics allude. "Why's Everybody Always Pickin' On Me?" is built around a re-recorded sample of "Spooky", by Mike Sharpe as performed by Classics IV and also features a small lift from the Bill Cosby track "Greasy Kid Stuff." Finally, the track "Your Only Friends Are Make Believe" features a chorus melody lifted from the Duran Duran song "Hungry Like the Wolf." "Lift Your Head Up High (And Blow Your Brains Out)" is built around a sample from "Get Up and Boogie" by the Silver Convention.
