Input: Question: What city is Harlan's alma mater located in? Passage 1:Giovanna married Tsar Boris III of Bulgaria in the Basilica of St Francis of Assisi, Assisi in October 1930, in a Roman Catholic ceremony, attended by Italian dictator Benito Mussolini. Bulgarians deemed her a good match, partly because her mother, Elena of Montenegro, was of Slavic ethnicity. At a second ceremony in Sofia, Giovanna (who herself was daughter of a Roman Catholic father and a formerly Orthodox mother) was married in an Eastern Orthodox Church ceremony, bringing her into conflict with the Roman Catholic Church. Giovanna adopted the Bulgarian version of her name, Ioanna. Giovanna knew the Pope's Apostolic Visitor to Bulgaria, Archbishop Angelo Roncalli, the future Pope John XXIII who was able to help her. She and Boris had two children: Marie Louise of Bulgaria, born in January 1933, and then the future Simeon II of Bulgaria in 1937.
Passage 2:Following the death of military dictator and de facto ruler of Nigeria, General Sani Abacha in 1998, his successor General Abdusalami Abubakar initiated the transition which heralded Nigeria's return to democratic rule in 1999. The ban on political activities was lifted, and political prisoners were released from detention facilities. The constitution was styled after the ill-fated Second Republic which saw the Westminster system of government jettisoned for an American Presidential system. Political parties were formed (People's Democratic Party (PDP), All Nigeria Peoples Party (ANPP), and Alliance for Democracy (AD)), and elections were set for April 1999. In the widely monitored 1999 election, former military ruler Olusegun Obasanjo was elected on the PDP platform. On 29 May 1999, Obasanjo was sworn in as President and Commander-in-Chief of the Federal Republic of Nigeria.
Passage 3:In 1982, at age 22, he became the TV and radio voice of the NBA's Kansas City Kings (now the Sacramento Kings). He then was a basketball announcer for his alma mater, the University of Kansas, for one year, then went on to call games for the NFL's Kansas City Chiefs from 198593 after several years hosting and producing surrounding pre-game and post-game programming (coincidentally, current Packers play-by-play voice Wayne Larrivee left the Chiefs position open when he began a thirteen-year run as the voice of the Chicago Bears). Harlan also split time with the University of Missouri (198689) calling football and basketball games, and worked as the play-by-play voice of the NBA's Minnesota Timberwolves for nine seasons (198998). On the network level, Harlan called NFL football for NBC in 1991, college football for ESPN in 199293, NFL for Fox from 199497, and joined Turner Sports in 1996 to cover NBA playoff games (he would begin calling games throughout the entire season in 1997, which he continues to do to this day). He began working for CBS in 1998.
