Input: Consider Input: 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.

Input: Consider Input: Question: What is the modern day country of Focsani? Passage:Orleanu's family were originally Ottoman Greeks of Phanariote descent who entered the Wallachian boyar class. Wealthy people, they settled in Buzău County and then Focșani, where Orleanu was born, ultimately moving to Galați. He graduated from the private Institutele Academice in Iași in 1876. Orleanu then studied law at the University of Paris, obtaining a doctorate in 1881. His thesis, published the following year, deals with illegitimate children in Roman law, and is his chief written work. After returning home, he entered the magistracy, holding a series of posts: prosecutor at the Iași tribunal (1882), then in Bucharest, judge at the Putna County tribunal (1882), president of the Dorohoi tribunal (1883), followed by Râmnicu Sărat (1884), prosecutor at the Galați appeals court (1887-1889). He retired from the judicial system in 1889, entering politics and joining the National Liberal Party (PNL). First elected to the Assembly of Deputies in 1895, he was returned for a number of terms. A fervent supporter of industrialization, from November 1909 to December 1910, he served as Minister of Industry and Commerce under Ion I. C. Brătianu. He authored the 1909 law restricting the right of some 160,000 state employees to unionize and strike; this was called the Orleanu Law or, by its socialist adversaries, the "wicked law".

Input: Consider Input: Question: What rank did the person who Fontes served under as the head of the CJ5 staff hold?  Passage:Early in the Global War on Terror, Fontes served at US Central Command J5 overseeing issues of political-military cooperation in Afghanistan. In June 2004, she was moved to Combined Forces Command - Afghanistan headquarters in Kabul and served under David Barno as the head of the CJ5 staff for political-military coordination. Her staff was responsible for keeping General Barno "on message", overseeing the policies impacting military operations, and performing liaison work with both the Afghan Ministry of Defense and United Nations Assistance Mission in Afghanistan. At the end of her first year in Afghanistan and following Karl Eikenberry's assumption of command from Barno, Fontes volunteered to lead the Provincial Reconstruction Team (PRT) in Tarinkot. Daniel Green, the political adviser for the PRT, reported that though some Soldiers at the PRT had initial concerns due to her gender, those worries were shortly put to rest. She had been active in engaging with the Afghan people. Green said that Fontes, then a Lieutenant Colonel, pitched in a few hundred dollars of her own money to host a lunch on the PRT for local Afghan leaders. An article in Vanity Fair relates a story that she once refused to depart a meeting with Afghan elders in Chora District under threat of small arms fire, for fear of appearing weak in the face of the Taliban. Green asserts that in early 2006, she survived the first suicide vehicle-borne improvised explosive device attack in Urozgan Province due in part to the device's failure to detonate all of the mortar shells of which it was comprised. She departed Afghanistan in May 2006 to attend the US War College, graduating in 2007. She had been promoted that year to colonel. She was subsequently assigned as the chief of the American Security Assistance Office in Pakistan.
