Q: 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.

Q: Question: Was the town where Kopanski went to military college larger than the town where he was employed as a lecturer? Passage:In 1962, when only 14, he was fascinated by the success of the Arab national and anti-colonial forces that defeated the French colonial armies in the Algerian War, gaining independence for their country. When attending a military college in Kętrzyn (Ger. Rastenburg) in 1966-1969, he actively opposed the Polish communist regime during the 1968 Polish political crisis, and as a result was expelled from the Officer School, and became a political prisoner for the first time. He continued his studies at the University of Silesia in Katowice, and after graduation was employed there as a lecturer,adiunct and researcher. In 1980-81, when Poland was swept by a wave of anti-communist strikes, and around ten million joined the anti-communist Solidarity trade union, Kopański co-founded a branch of this broad grassroots social movement at the University of Silesia.
