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.

[EX Q]: original question: What is the antiparticle of [Up antiquark]?
answer: up quark
answer type: Quark.
[EX A]: Which is the antiparticle of [Up antiquark]?

[EX Q]: original question: Which musical recording has the tracks of [Djoloff, Djoloff]?
answer: djoloff, djoloff
answer type: Musical Recording.
[EX A]: [Djoloff, Djoloff] is a track that is in what musical recording?

[EX Q]: original question: Which measurement system has the illuminance units of [Lux]?
answer: international system of units
answer type: Measurement System.
auxiliary information: The lux is the SI unit of illuminance and luminous emittance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. It is analogous to the radiometric unit watts per square metre, but with the power at each wavelength weighted according to the luminosity function, a standardized model of human visual brightness perception. In English, "lux" is used in both singular and plural.
[EX A]:
[Lux] is an illuminance unit of which measurement system?
