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 Christian doctrine of the Trinity defines God as three consubstantial persons, expressions, or hypostases: the Father, the Son, and the Holy Spirit; "one God in three persons". The three persons are distinct, yet are one "substance, essence or nature". In this context, a "nature" is what one is, while a "person" is who one is. According to this central mystery of most Christian faiths, there is only one God in three persons: while distinct from one another in their relations of origin and in their relations with one another, they are stated to be one in all else, co-equal, co-eternal and consubstantial, and "each is God, whole and entire". Accordingly, the whole work of creation and grace is seen as a single operation common to all three divine persons, in which each shows forth what is proper to him in the Trinity, so that all things are "from the Father", "through the Son" and "in the Holy Spirit". Terms such as "monotheism" and "incarnation", are not found in the Bible, but they denote theological concepts concerning Christian faith that are believed to be contained in the Bible. Even the term "Bible" is not found in the Bible. "Trinity" is another such term.
