Q: Question: Which of the two universities that Kaplan worked at between 1949 and 1957 was established first? Passage 1:Nathan Oram Kaplan (June 25, 1917 – April 15, 1986) was an American biochemist who studied enzymology and chemotherapy. After completing a B.A. in chemistry at UCLA in 1939, Kaplan studied carbohydrate metabolism in the liver under David M. Greenberg at the University of California, Berkeley medical school. He earned his Ph.D. in 1943. From 1942 to 1944, Kaplan participated in the Manhattan Project, and then spent a year as an instructor at Wayne State University. From 1945 to 1949, Kaplan worked with Fritz Lipmann at Massachusetts General Hospital to study coenzyme A. Kaplan went to the University of Illinois College of Medicine as an assistant professor in 1949, and from 1950 to 1957 he worked at the McCollum-Pratt Institute of Johns Hopkins University. In 1957, he was recruited to head a new graduate program in biochemistry at Brandeis University. In 1968, Kaplan moved to the University of California, San Diego, where he studied the role of lactate dehydrogenase in cancer. He also founded a colony of nude mice, a strain of laboratory mice useful in the study of cancer and other diseases. In 1981, Kaplan became a founding member of the World Cultural Council.
 Passage 2:Peter Dinklage is an American actor and producer. Dinklage studied acting at the Bennington College where he starred in a number of amateur stage productions. He made his film debut in the 1995 comedy-drama Living in Oblivion. After appearing in a series of supporting parts in much of the 1990s and early 2000s, he made his breakthrough by starring in the Tom McCarthy-directed comedy-drama The Station Agent (2003), which had him play a railroad-obsessed introvert who inherits an abandoned train depot. He was cast in the role by director Tom McCarthy who recalled fondly his appearance in McCarthy's play The Killing Act (1995). For his performance, he received a Screen Actors Guild Award nomination for Best Actor and an Independent Spirit Awards nomination for Best Male Lead. In the same year, Dinklage played the title role in the play Richard III at The Public Theater. He also played a children's book author in the comedy Elf. In 2006, he appeared in the Sidney Lumet-directed crime film Find Me Guilty. He followed with roles in the films Underdog (2007), the British film Death at a Funeral (2007), with its American remake of the same name (2010) and Trumpkin in the high fantasy film  (2008).
 Passage 3:While in New York, Fornia studied with Emil Fischer and Sofia Scalchi in New York City and then, under Fischer's advice, moved to Berlin in 1899 to study under Selma Nicklass-Kempner. Kempner, later the teacher of Frieda Hempel, trained her as a coloratura soprano. She made her professional début with the Hamburg State Opera in 1901 as Eudoxie in Halévy's La Juive. Over the next two years she sang mostly coloratura soprano roles in Germany and France, largely with the Hamburg State Opera who offered her a contract. Her other roles in Hamburg included Rosina in The Barber of Seville and the Queen of the Night in The Magic Flute. From the Fall of 1902 through the summer of 1903 she studied with Jean de Reszke in Paris. Reszke was convinced the Fornia was actually a mezzo-soprano and trained her voice accordingly. Under Reszke's recommendation to Henry Savage, Fornia returned to America in August 1903 to join the Savage English Grand Opera Company where she sang both mezzo-soprano and soprano roles until 1906. Her first performance with the company was as Siébel in Charles Gounod's Faust at the Brooklyn Academy of Music on 21 September 1903. Her other roles with Savage's company included Musetta in Giacomo Puccini's La bohème, Nedda in Pagliacci, Santuzza in Cavalleria rusticana, both Brünnhilde and Sieglinde in The Valkyrie, both Elisabeth and Venus in Wagner's Tannhäuser, and both Leonora and Azucena in Verdi's Il trovatore.
