In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Q: Question: How long had the Canadian Pacific Railway been in operation for the year the Electro-Motive Diesel entered full production? 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:The Visalia, CA native was a multi-sport athlete at Mt. Whitney High School where he excelled in football and baseball. Michael's career statistics of 162 catches for 3,005 yards and 44 touchdowns still stand as one of the top performances in CIF history. Young was recruited by every major college football program in the Country, accepting recruiting visits to Notre Dame, USC, Nebraska, Oklahoma, Washington and UCLA. At UCLA, he played both football and baseball. Young helped the Bruins to two Pac-10 titles, two Rose Bowl (1983, 1984) victories and a Fiesta Bowl (1985) win. Michael was an Academic All-Pac 10 selection in 1984 and in the 1984 Rose Bowl game, Young had 5 receptions for a total of 127 yards, including a 52-yard touchdown pass from Rick Neuheisel. As a two-sport athlete, Young was drafted by the New York Mets in 1983 after hitting .311 his sophomore year. Following the 1985 Fiesta Bowl win, in which he was the leading receiver, he was drafted by the Los Angeles Rams. He earned a bachelor's degree in sociology from UCLA.
