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.
Input: original question: Which airport is the hub for [Midway Airlines] ?
answer: chicago midway international airport
answer type: Airport.
auxiliary information: Midway Airlines was a United States airline founded on October 13, 1976, by investor Irving T. Tague. Although it received its operating certificate from the Civil Aeronautics Board prior to the passage of the Airline Deregulation Act in 1978, it is widely recognized as the first post-deregulation start-up. The airline commenced operations in 1979. The airline was intended to breathe new life into Chicago Midway International Airport, then called Chicago Midway Airport, which had lost most of its scheduled flights to O'Hare International Airport. Midway Airlines and the revitalized airport were advertised as a trouble-free alternative to O'Hare, and both of these spurred re-development and growth on Chicago's South Side. The airport was billed as a convenient ten- to fifteen-minute drive from downtown Chicago.
