Question: Of the cities where the two hospitals where Ruhakana worked are located, what is the population of the largest? Passage 1:Thérésa became one of the leaders of Parisian social life. Her salon was famous and she was one of the originators of the Greek Revival Directoire style women's fashions of the French Directory period. She was a very colorful figure; one story is that she was said to bathe in the juice of strawberries for their healing properties. She once arrived at the Tuileries Palace, then the chief residence of Napoleon Bonaparte, supported by a black page, with eight sapphire rings and six toe rings, a gold bracelet on each ankle and nine bracelets on each arm. To top the look off Theresa had a head band covered in rubies. On another occasion she appeared at the Paris Opera wearing a white silk dress without sleeves and not wearing any underwear. Talleyrand commented: "Il n'est pas possible de s'exposer plus somptueusement!" ("One could not be more sumptuously unclothed!").
 Passage 2:Rugunda was born in Kabale District on 7 November 1947. As a young boy, he would often sit and read the newspapers to his father Surumani Rugunda, and it is these experiences at an early age that sparked his later interest in politics. Rugunda attended Kigezi High School and Busoga College Mwiri where he served as head prefect, before joining the Makerere University Medical School and later the University of Zambia where he studied medicine, graduating a Bachelor of Medicine and Bachelor of Surgery. He later studied at the University of California, Berkeley and obtained a Master of Science in public health. Before joining Ugandan politics, Rugunda worked as medical officer in Zambia, as a physician at the District of Columbia General Hospital in Washington, D. C., and at Kenyatta National Hospital in Nairobi, Kenya.
 Passage 3:In 1963-1964 Walker was a resident artist at the Oldenburgisches Staatstheater. He then became a resident artist at the Cologne Opera from 1964-1966. Other contracts soon followed with such companies as the Cincinnati Opera, the Houston Grand Opera, the Lyric Opera of Kansas City, the Miami Opera, and the New Orleans Opera among others. In 1971 he created the role of Jonathan Gilourin in the world premiere of Dominick Argento’s Colonel Jonathan the Saint at the Denver Lyric Opera. In 1974 he was handpicked by Sir Georg Solti to sing the role of the Evangelist in Bach's St Matthew Passion with the Chicago Symphony Orchestra (CSO). He returned twice more for performances with Solti and the CSO for performances of the Shepherd in Stravinsky's Oedipus Rex (1976) and Beethoven's Missa Solemnis (1977); the latter of which was recorded for London Records.
