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: What is the unit of absorbed dose in [International System of Units]?
answer: gray
answer type: Unit of Absorbed Dose.
auxiliary information: The International System of Units is the modern form of the metric system and is the world's most widely used system of measurement, used in both commerce and science. It comprises a coherent system of units of measurement built on seven base units. It defines twenty-two named units, and includes many more unnamed coherent derived units. The system also establishes a set of twenty prefixes to the unit names and unit symbols that may be used when specifying multiples and fractions of the units. The system was published in 1960 as the result of an initiative that started in 1948. It is based on the metre-kilogram-second system of units rather than any variant of the centimetre‚Äìgram‚Äìsecond system. SI is intended to be an evolving system, so prefixes and units are created and unit definitions are modified through international agreement as the technology of measurement progresses and the precision of measurements improves. The 25th General Conference on Weights and Measures in 2014, for example, discussed a proposal to change the definition of the kilogram.
In the [International System of Units], what is the unit of absorbed dose?

original question: What is the orbit type of a satellite whose launch vehicle is [Ariane 5]?
answer: geostationary orbit
answer type: Satellite Orbit Type.
auxiliary information: Ariane 5 is a European heavy lift launch vehicle that is part of the Ariane rocket family, an expendable launch system used to deliver payloads into geostationary transfer orbit or low Earth orbit. Ariane 5 rockets are manufactured under the authority of the European Space Agency and the Centre National d'Etudes Spatiales. Airbus Defence and Space is the prime contractor for the vehicles, leading a consortium of sub-contractors. Ariane 5 is operated and marketed by Arianespace as part of the Ariane programme. Astrium builds the rockets in Europe and Arianespace launches them from the Guiana Space Centre in French Guiana. Ariane 5 succeeded Ariane 4, but was not derived from it directly. Ariane 5 has been refined since the first launch in successive versions, "G", "G+", "GS", "ECA", and most recently, "ES". ESA originally designed Ariane 5 to launch the Hermes spaceplane, and thus intended it to be human rated from the beginning. Two satellites can be mounted using a SYLDA carrier. Three main satellites are possible depending on size using SPELTRA. Up to eight secondary payloads, usually small experiment packages or minisatellites, can be carried with an ASAP platform.
Which is the orbit type of a satellite whose launch vehicle is [Ariane 5]?

original question: [Nigredo Hotel] belongs to which opera genre?
answer: chamber opera
answer type: Opera Genre.
auxiliary information: Nigredo Hotel is a chamber opera in one act composed by Nic Gotham to a libretto by Ann-Marie MacDonald. It premiered on 13 May 1992 at the Tarragon Theatre in Toronto in a production by Tapestry New Opera Works who had commissioned the opera. The production won two Dora Awards and the work was nominated for the Floyd S. Chalmers Canadian Play Award. Subtitled "an operatic thriller", it is set in Room 7 of a run-down hotel which takes its name from the Jungian concept of Nigredo or "dark night of the soul". The story involves an encounter between the beautiful but crazed woman who runs the hotel and a brain surgeon forced to take refuge there after crashing his car.
