Input: Question: Which of the non-Israeli countries that Soviet Jews migrated to has a larger population? Passage 1: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.
 Passage 2:In April 1941, Drummond joined the Women's Royal Naval Service (WRNS) and served as a writer (equivalent in rank to able seaman). She was commissioned as a third officer (equivalent to sub-lieutenant) in October, with seniority from 25 September. She was promoted to second officer (equivalent to lieutenant) in October 1942, with seniority from 29 August 1942, and in early 1944 joined the staff of Commander-in-Chief, Plymouth. She was "responsible for the administration and paperwork relating to the command's role in operation Neptune": as such, she was the first woman to learn about the Normandy landings. In April 1944, she was made an acting first officer (equivalent to lieutenant commander) with seniority from 5 April; this promotion was confirmed in August. After the Normandy landings, she was posted to India, where she worked as assistant secretary to its flag officer. Then, with promotion to superintendent (equivalent to captain), she joined the staff of Commander-in-Chief, East Indies Fleet.
 Passage 3: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.
