Definition: Compose a new way to ask the same question. The new question must be asking the exact same thing as the original question does. Without any other information, you should be able to tell that the original question and the new question are the same. Preserve bracketed phrases in your new question. You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.

auxiliary information: The National Railroad Passenger Corporation, doing business as Amtrak, is a partially government-funded American passenger railroad service. It is operated and managed as a for-profit corporation, and provides medium- and long-distance intercity service in the contiguous United States. Amtrak was founded in 1971 through the government-sponsored consolidation of most of the preexisting passenger rail companies in the United States. Amtrak operates more than 300 trains each day on 21,300 miles of track with select segments having civil operating speeds of 150 mph and connecting more than 500 destinations in 46 states in addition to three Canadian provinces. In fiscal year 2014, Amtrak served 30.9 million passengers and had $2.189 billion in revenue while employing more than 20,000 people. Nearly two-thirds of passengers come from the ten largest metropolitan areas and 83% of passengers travel on routes of 400 miles or less. Its headquarters is at Union Station in Washington, D.C. The name "Amtrak" is a portmanteau of the words "America" and "trak", the latter itself a sensational spelling of "track".
