In this task, you're given an ambiguous question (which can be answered in more than one way). Your task is to write a question that clarifies the given question in such a way that the generated question has one unique answer.

Let me give you an example: Lucifer how many episodes are in season 3?
The answer to this example can be: How many episodes of season 3 of Lucifer were there, including bonus episodes?
Here is why: The generated question clarifies the input question by asking about bonus episodes because if the question is about regular episodes only then the answer will be different than including the bonus episodes.
