Input: Question: How many people live in the city that Taube was born? Passage 1:Taube was born in New York City in 1939 to Count Arvid E. Taube and Alice N. Taube. After attending Kent School, he enrolled at Princeton University, from which he graduated in 1961 with a B.A. in sociology. He went on to receive a doctorate in sociology from American University in 1983. He began working at the National Institute of Mental Health in 1961 as a statistician, and continued to work there until 1987, eventually becoming director of their Division of Biometry and Applied Sciences. He also began a mental health economics program at the NIMH and started their "Mental Health, United States" series, a regularly published report cataloging mental health statistics in the United States. In 1980, he was awarded the Administrators Award for Meritorious Achievement from the Alcohol Drug Abuse and Mental Health Agency. In 1987, he became a professor in the Department of Mental Hygiene at the Johns Hopkins School of Hygiene and Public Health, where he continued to teach until his death. On September 28, 1989, he died of congestive heart failure at the Johns Hopkins Hospital in Baltimore, Maryland. In 1990, the American Public Health Association established the Carl Taube Award for Lifetime Contribution to the Field of Mental Health in honor of his work.
 Passage 2:Between 1989 and 2006, about 1.6 million Soviet Jews and their non-Jewish relatives and spouses, as defined by the Law of Return, emigrated from the former Soviet Union. About 979,000, or 61%, migrated to Israel. Another 325,000 migrated to the United States, and 219,000 migrated to Germany. According to the Israeli Central Bureau of Statistics, 26% of the immigrants who arrived in Israel were not considered Jewish by Orthodox interpretations of Jewish law (which only recognizes matrilineal descent), but were eligible for Israeli citizenship under the Law of Return due to patrilineal Jewish descent or marriage to a Jew. The majority of the immigrant wave were Ashkenazi Jews; however, a significant proportion were Mizrahi groups such as the Mountain Jews, Georgian Jews, and Bukharan Jews – with each ethnic group bringing its own distinctive culture to Israel. The group successfully integrated economically into Israel: in 2012, the average salary of FSU (Former Soviet Union) immigrants was comparable to that of native-born Israeli Jews.
 Passage 3:In 1996, Electro-Motive Diesel entered full production on their , 16-cylinder H-engine, and all SD90MACs made from then on used that for its prime mover. Locomotives fitted with this engine are sometimes referred to as SD90MAC-H locomotives. Later versions of the SD90MAC-H feature a Phase II cab, with a new nose which offers higher visibility from the cab than the old nose. The SD90MAC-H did not prove popular with railroads and less than 70 were built, including Electro-Motive Diesel demonstrator units. Since the SD90MAC-H had such a large prime mover, it didn't offer the same operational flexibility as smaller units, limiting its possible customer base to only the largest railroads. Also, since the H-engine was a new design it hadn't reached the same level of reliability as EMD's previous engine. The low reliability on such a large engine was an especially bad combination since the loss of one engine in a train meant the loss of a larger percentage of pulling power than had a smaller engine failed. In the end the SD90MAC-H was only delivered to two railroads, the Union Pacific Railroad and the Canadian Pacific Railway. The Canadian Pacific locomotives were part of an earlier order for 710-engine equipped SD90MAC locomotives that was still in production when Electro-Motive Diesel switched over to the H-engine.
