You will be given a definition of a task first, then some input of the task.
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.

original question: Which engine is [Straight-six engine]
answer: bmw 3.0l 6 cylinder 300 hp 300 ft-lbs turbo
answer type: Engine.
auxiliary information: The straight-six engine or inline-six engine is an internal combustion engine with the cylinders mounted in a straight line along the crankcase with all the pistons driving a common crankshaft. The bank of cylinders may be oriented at any angle, and where the bank is inclined to the vertical, the engine is sometimes called a slant-six. The straight-six layout is the simplest engine layout that possesses both primary and secondary mechanical engine balance, resulting in much less vibration than engines with fewer cylinders.
Output:
What is the engine that is a [Straight-six engine]?
