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.

[Q]: original question: Which computer peripheral class has [The Spectrum Emulator]?
answer: kempston joystick interface, magnetic tape data storage
answer type: Computer Peripheral Class.
auxiliary information: Spectrum emulator written in x86 assembler. Emulates a multiface one, kempston joystick and tape drive (via ROM traps) to save data as files in emulator directory. Emulates many, but not all undocumented Z80 instructions but is not cycle accurate as it was originally developed on an original IBM AT (6Mhz 286)! When originally released it managed to run close to full Spectrum speed on a 40MHz 386 and source code is now available on Google Code.
[A]: [The Spectrum Emulator] is part of which peripheral class?


[Q]: original question: How many geographical feature are there in the subcategories of [Rock]?
answer: 68
answer type: Geographical feature category.
auxiliary information: In geology, rock is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example, the common rock granite is a combination of the quartz, feldspar and biotite minerals. The Earth's outer solid layer, the lithosphere, is made of rock. Rocks have been used by mankind throughout history. From the Stone Age, rocks have been used for tools. The minerals and metals found in rocks have been essential to human civilization. Three major groups of rocks are defined: igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, which is an essential component of geology.
[A]: What is the number of geographical features that belong to the subcategory of [Rock]?


[Q]: original question: What type of transmission does [Ford C4 transmission] use?
answer: automatic transmission
answer type: Transmission Classification.
auxiliary information: The Ford C4 is a three-speed, medium-duty automatic transmission introduced on 1964 model year vehicles and produced through 1981. The C4 was designed to be a lighter and more simple replacement for the original Ford-O-Matic two speed transmission being used in smaller, less powerful cars. Because of its cast iron construction, the Ford-O-Matic was very heavy. In designing the C4, Ford used an aluminum alloy, three-piece case. The aluminum case and the use of a more simple Simpson planetary gearset reduced the weight significantly. It was primarily used with Ford's inline six-cylinder engines and small V8 engines, usually up to 302 in¬≥. By comparison, the 351 Windsor and 351 Cleveland small and intermediate-block engines were backed by the medium-duty FMX or the heavy-duty C6 that debuted in 1966. Some C4s were built with a larger spread bell housing to use with 351M V8s, but these are rare. A few were also used with FE engines, mostly the 390. in full-size cars. The early model C4 used a .788-inch 24-spline input shaft, which was upgraded in 1970 to 26-spline and .839-inch. The upgrade also included a matching clutch hub of 26-spline.
