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 fictional calendar system is preceded by [Before Battle of Yavin]?
answer: after battle of yavin
answer type: Fictional Calendar System.
auxiliary information: The Before Battle of Yavin time system (or BBY) is the calendar system used in later works of the Star Wars fictional universe for events occurring before The Battle of Yavin and the destruction of the first Death Star as seen in Star Wars Episode IV: A New Hope. The BBY system counts in reverse up to that event. (5 BBY occurs before 4 BYY chronologically)

[Before Battle of Yavin] precedes what fictional calendar system?
